Detailed description of the invention
Below in conjunction with the accompanying drawings, the better embodiment of reciprocating power tool is described.
Refer to Fig. 1 and Fig. 2, disclose the reciprocating power tool 100 of an embodiment, including casing 110,
The gear-box 120 being arranged in casing 110, the reciprocating lever 130 being arranged in gear-box 120 and gear-box
120 matched case lids 140 and the motor 150 being arranged in casing 110.The company of being additionally provided with in gear-box 120
It is access to the drive mechanism 160 of compound lever 130 and motor 150.Motor 150 is by the driver in gear-box 120
Structure 160 drives reciprocating lever 130 the most reciprocating along it, and reciprocating lever 130 then can drive work head (not
Label) reciprocating.
Casing 110 includes main body 112 and the handle 114 being connected with main body 112.Gear-box 120 and motor 150
It is contained in main body 112.The setting of handle 114 makes reciprocating power tool 100 be easy to carry and operate,
Handle 114 can be used for driving motor 150 to work, it is possible to so that electric power connection line is from hands with internal battery
Draw to be connected with external power source at handle 114.
Refer to Fig. 2, in reciprocating lever 130 is arranged on gear-box 120 and axially reciprocating can be made.Gear-box
Being further fixed on fairlead 170 in 120, reciprocating lever 130 is axially slidably arranged in fairlead 170.As
This, motor 150 drives reciprocating lever 130 at fairlead 170 by the drive mechanism 160 in gear-box 120
Interior the most reciprocating along it.The both sides of reciprocating lever 130 are respectively fixed with the first locating part 182 and second
Locating part 184, is respectively intended to and the first locating slot 122 and the second location on gear-box 120 and case lid 140
Groove 142 is slidably matched.When reciprocating lever 130 is reciprocating, the first locating part 182 and second of both sides
Reciprocating lever 130 can be positioned by locating part 184 respectively from the both sides of reciprocating lever 130, prevents reciprocating lever
Rotating during 130 axially-movable, the stability of location is higher.First locating part 182 and the second locating part
184 stagger setting with fairlead 170 in the axial direction of reciprocating lever 130, can simplify the structure of fairlead 170,
Also its manufacturing cost is reduced.
In the present embodiment, the first locating part 182 and the second locating part 184 are integral type structure, and they are fixed
Position pin 180 highlights two ends of reciprocating lever 130.Refer to Fig. 2, alignment pin 180 is perpendicular to reciprocating lever
The axis X of 130, and run through reciprocating lever 130.Specifically, reciprocating lever 130 is provided with through hole (not shown),
Alignment pin 180 connects with through hole interference, and the two ends of alignment pin 180 protrude from the two of reciprocating lever 130 respectively
Side, to form the first locating part 182 and the second locating part 184 respectively.As in figure 2 it is shown, in gear-box 120
Wall is provided with the first locating slot 122 coordinated with the first locating part 182；It is provided with on case lid 140 and the second limit
The second locating slot 142 that position part 184 coordinates, wherein the first locating part 182 and the second locating part 184 are stretched respectively
Enter in the first locating slot 122 and the second locating slot 142 and can slide along the axial direction of reciprocating lever 130.
So, the both sides of reciprocating lever 130 are provided with locating part for preventing reciprocating lever 130 from rotating, reciprocating lever 130
During reciprocating motion, the stability of location is higher.It addition, it may be noted that alignment pin 180 can also be not orthogonal to
The axis X of reciprocating lever 130, as long as its two ends all highlight reciprocating lever 130, and can respectively with the first locating slot
122 and second locating slot 142 be slidably matched.
In the present embodiment, the first locating part 182 of reciprocating lever 130 both sides and the second locating part 184 are integrated
Formula structure.It is appreciated that being respectively formed locating part in the both sides of reciprocating lever 130 can also be by other means
Obtain.As can also be to be inserted into, with two alignment pins, the through hole being opened on reciprocating lever 130 respectively from both sides
In, now effect is identical with arranging an alignment pin running through reciprocating lever 130.Can also be, at reciprocating lever
The both sides of 130 the most one-body molded go out a projection.It is also possible that the first locating part 182 and the second locating part
In 184 one is alignment pin, and another is integrated projection on reciprocating lever 130.Additionally, when reciprocal
When first locating part 182 of bar 130 both sides and the second locating part 184 are not integral type structure, they
Position on reciprocating lever 130 is axial can be corresponding, it is also possible to staggers, as long as can be with the first locating slot 122
Reach with the second locating slot 142 and be slidably matched.
The first locating slot 122 at least two kinds of set-up modes on gear-box 120.A kind of mode is: gear
Being fixed with keeper 124 on case 120 inwall, aforementioned first locating slot 122 is opened on keeper 124.By
It is arranged on keeper 124 in the first locating slot 122, when the first locating slot 122 abrasion increases, permissible
The stability of location is recovered quickly and easily by changing keeper 124.Another way is: first is fixed
Position groove 122 is directly opened on gear-box 120 inwall, at this time it is also possible to be interpreted as the first locating slot 122
Be opened in one with the integrated keeper of gear-box 120 on.
Refer to Fig. 3 and Fig. 4, the one side of case lid 140 is provided with a pair gusset 144, aforementioned second locating slot
142 are formed between a pair gusset 144.A pair gusset 144 is the another side punching press from case lid 140 and rolls over
Bending becomes, and this kind mode technique is simple and cost is relatively low.Certainly, gusset 144 can also be that sheet material passes through weldering
The mode such as connect is fixed to be formed on the side of case lid 140.It may be noted that the second locating slot 142 can also is that
On the one side of case lid 140, depression is formed.Case lid 140 is by securing member 190(screw, bolt etc.) can
Releasably connect with gear-box 120, facilitate reciprocating lever 130 and the installation of locating part thereon and adjustment.The
Two locating slots 142 are arranged on case lid 140, directly utilize spacing second locating part 142 of case lid 140, past
The element of compound power tool 100 is few, easy to assembly.
To sum up, in above-mentioned reciprocating power tool 100, the both sides of reciprocating lever 130 are provided with locating part,
It is slidably matched to prevent reciprocating lever 130 from rotating with the first locating slot 122 and the second locating slot 142 respectively, fixed
The stability of position is higher.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed,
But therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that, for this area
Those of ordinary skill for, without departing from the inventive concept of the premise, it is also possible to make some deformation and
Improving, these broadly fall into protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be with appended
Claim is as the criterion.
