Abstract

The invention relates to a multi-functional socket wrench head which can be twisted in a direction tilted to the axis of the socket wrench head at a certain angle so as to twist a bolt or a nut. The technical scheme includes that a six-ridge ball passes through a neck portion and is fixed concentrically with a tower-shaped body, a concentric main sleeve opening is arranged at one end of the tower-shaped body and used for being sleeved on the bolt or the nut, the tower-shaped body comprises a sleeve body and a socket body which are fixed together concentrically, the sleeve body includes at least two layers of concentric hexagonal prisms, the socket body is formed by a layer of cylinder, an auxiliary sleeve hole in a hexagonal prism shape is penetrated through the wall of the tower-shaped body, perpendicular to the central line of the tower-shaped body and communicated with the main sleeve opening, and the six-ridge ball is provided with six arc-shaped lateral side and one upper end face. The socket wrench head is simple in structure, novel and unique, various in combining form, easy to operate and good in effect.

Description

Collet head
Technical field
The present invention relates to daily instrument, particularly tighten or unload a kind of multi-functional collet head of usefulness of loosening the screw a little.
Background technology
Box spanner is a common instrument in the life, also is the repair outfit that must be equipped with in the repairing trades, and box spanner is specially adapted to turn status very narrow and small or cave in the very bolt or the nut of depths; Because an equipment or the bolt or the nut that install differ in size, the present position is different with the space, need be with varying in size during work; A large amount of box spanners and collet head different in size; Use very inconveniently, owing to have problems on the present sleeve head structure, can not use bigger strength to turn bolt or nut under the situation of several collet heads having only; Can not under heeling condition, turn bolt or nut; The combining form of sleeve is simple, and inefficiency is so improvement is imperative.
Summary of the invention
To above-mentioned situation, in order to overcome the prior art defective, the invention provides a kind of multi-functional collet head, can effectively solve number of tools many, use inconvenient and ineffective problem.
The technical scheme that the present invention solves is, comprises six rib bulbs and turriform body, and six rib bulbs pass through neck and turriform body concentric is fixed together; Turriform body one end has the main running-on of concentric, and main running-on is used for overlapping connecting bolt or nut, and the turriform body comprises belled body and sleeve body; Belled body comprises two-layer at least coaxial positive hexagonal prism, and sleeve body is to be formed by one deck cylinder, and belled body and sleeve body concentric are fixed together; Secondary trepanning is arranged on the turriform body wall,, and communicate with main running-on perpendicular to turriform body center line; Secondary trepanning is positive hexagon hole, and six rib bulbs have six arcuate flanks and a upper surface.
The present invention is simple in structure, and is novel unique, combined and instant, and processing ease, effective.

The specific embodiment
Elaborate below in conjunction with the accompanying drawing specific embodiments of the invention.
Provide by Fig. 1-Fig. 4; The present invention includes six rib bulbs and turriform body, six rib bulbs (1) are fixed together through neck (2) and turriform body (3) concentric, and said turriform body has the main running-on (10) of concentric; Said six rib bulbs (1) have a upper surface (8) and six arcuate flanks; The cross section of said six rib bulbs (1) is a regular hexagon, and the external diameter of said neck (2) is less than said six rib bulb external diameters and this body diameter of turriform, and said main running-on (10) cross section is a regular hexagon.
Said turriform body (3) comprises belled body (7) and sleeve body (5), and belled body (7) has the structure of two-layer at least coaxial positive hexagonal prism, and sleeve body (5) is to be formed by one deck cylinder, and belled body (7) and sleeve body (5) concentric are fixed together.Have secondary trepanning (4) to run through on turriform body (3) wall, perpendicular to turriform body center line, and communicate with main running-on (10), secondary trepanning (4) is positive hexagon hole, and six rib bulbs (1) are made up of six arcuate flanks and a upper surface.
Main running-on (10) has by two-layer at least positive hexagonal prism concentric and combines formed stratiform space; Have the secondary trepanning (4) of positive hexagonal prism shape to connect on turriform body (3) wall, said secondary trepanning is perpendicular to turriform body axial line, and communicates with main running-on (10); The outer wall holding positioning ball (6) of at least one side of belled body (7), said positioning ball (6) roof pressure is in spring (9) outside, and spring (9) places in the wall of belled body (7).
When the present invention uses, can be used as extension bar or reducing extension bar and use; Also available supporting sleeve entangles six rib bulbs of the present invention, can on the direction that favours the certain angle in axle center of the present invention, twist the present invention, thereby reaches the purpose that turns bolt or nut; The present invention's use capable of being combined, (as shown in Figure 3) sleeve (11), sleeve (12), sleeve (13) are sleeved on together from big to small successively, can be used as the long handle sleeve and use; The belled body of the assembly that a plurality of sleeve combination are formed together inserts in the secondary trepanning of another sleeve; Form T type spanner (like Fig. 4); Three head of T type all can obtain the long arm of force and turn bolt, and six rib bulbs wherein can turn hexagon socket head cap screw favouring on the certain angle direction of hexagon socket head cap screw axial line; The present invention can with the supporting use of multiple instrument, like leatherhead open-end wrench, double offset ring spanner, box spanner, pneumatic impact spanner, also can be equipped with driver bit and use; The a whole set of jacket casing of the present invention is connected together, and under the effect of positioning ball, is difficult for loosening losing, and is convenient for carrying.
