Abstract
The invention discloses a fastening spanner, which comprises a positioning tool and pin bodies. The positioning tool is provided with a plurality of positioning holes. The pin bodies can be inserted into the positioning holes correspondingly. The side wall at the bottom end of each positioning hole is provided with a threaded through hole. Jack screws are arranged in the threaded through holes and pass through the threaded through holes so as to press the pin bodies on the inner walls of the positioning holes. In the invention, the positioning tool is provided with unthreaded holes and the cylindrical surfaces of the pin bodies are respectively locally provided with a plane. The pin bodies are in clearance fit with the unthreaded holes of the positioning tool and fixed on the positioning tool by the jack screws. If the pin bodies are fractured, the pin bodies can be taken out by rotating the jack screws so as to solve the problem that residual parts cannot be taken out after the pin bodies are fractured.
Description
Technical field:
The present invention relates to high-tension switch gear, the spanner that particularly a kind of isolating switch segment conductor that is used for gas-insulated metal-enclosed equipment is connected with contact.
Background technology:
In the prior art, the spanner that the isolating switch conductor is connected with contact, its structure is made up of orientation tool and shank, and orientation tool and shank adopt and are threaded.In use may there be the phenomenon of shank fracture in this spanner, and being positioned at the residual shank of wrench body can't take out, and causes fastening frock to scrap.In the process of fracture, conductor is damaged simultaneously.
Summary of the invention:
The invention provides a kind of easy to usely, the frock that operating efficiency is higher has solved the problem that the shank fracture causes the frock to scrap.
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, a kind of spanner is provided, comprise orientation tool and shank, several locating holes are arranged on the described orientation tool, the shank of can pegging graft in each locating hole; Described locating hole bottom sidewall is provided with tapped through hole, is provided with jackscrew in the tapped through hole; Described jackscrew passes screwed hole shank is pressed on the locating hole inwall.
Described locating hole inner wall smooth, the bottom sealing.
Described shank outer wall is provided with a plane, and this plan-position is corresponding with the tapped through hole position; Described jackscrew compresses this plane makes shank be pressed on the locating hole inwall.
Described several locating holes are 1-4 locating holes.
Described tapped through hole inwall is provided with internal thread, and the jackscrew outer wall is provided with external screw thread; Described jackscrew and tapped through hole are by being threaded.
The present invention adopts unthreaded hole at orientation tool, plane of shank face of cylinder localized design.The unthreaded hole of shank and orientation tool adopts matched in clearance, utilizes jackscrew that shank is fixed on orientation tool.If the shank fracture takes place, the rotation jackscrew can take out shank, thereby has solved the difficult problem that shank fracture back nubbin can't take out.
Description of drawings:
Fig. 1 is existing spanner structural representation;
Fig. 2 is a spanner structural representation of the present invention;
Fig. 3 is a spanner end view drawing of the present invention;
Fig. 4 is shank figure of the present invention.
Wherein: 1 is orientation tool; 2 is shank; 3 is locating hole; 4 is tapped through hole; 5 is jackscrew; 6 is the plane.
The specific embodiment:
Below in conjunction with accompanying drawing the present invention is done and to describe in further detail:
Referring to Fig. 2-4, a kind of spanner comprises orientation tool and shank, and several locating holes are arranged on the described orientation tool, the shank of can pegging graft in each locating hole; Described locating hole bottom sidewall is provided with tapped through hole, is provided with jackscrew in the tapped through hole; Described jackscrew passes screwed hole shank is pressed on the locating hole inwall.
Described locating hole inner wall smooth, the bottom sealing.
Described shank outer wall is provided with a plane, and this plan-position is corresponding with the tapped through hole position; Described jackscrew compresses this plane makes shank be pressed on the locating hole inwall.
Described several locating holes are 1-4 locating holes.
Described tapped through hole inwall is provided with internal thread, and the jackscrew outer wall is provided with external screw thread; Described jackscrew and tapped through hole are by being threaded.
At first to 4 unthreaded holes of orientation tool design, plane of shank face of cylinder localized design.Shank is put into the orientation tool unthreaded hole, from orientation tool side screwed hole jackscrew is installed, the turn jackscrew compresses the shank plane, makes the shank held stationary.If in use rupture, only need jackscrew is screwed out, fracture shank nubbin can be taken out, can use again behind the shank that more renews.At 4 unthreaded holes of orientation tool design, its objective is to occur wearing and tearing in two unthreaded hole uses, can use other 2 standby holes, can prolong spanner service time like this.
Above content is to further describing that the present invention did in conjunction with concrete preferred implementation; can not assert that the specific embodiment of the present invention only limits to this; for the general technical staff of the technical field of the invention; without departing from the inventive concept of the premise; can also make some simple deduction or replace, all should be considered as belonging to the present invention and determine scope of patent protection by claims of being submitted to.
