Description
Technical field：
The utility model is related to field of tool, specifically a kind of multipurpose wrench.
Background technology：
In the work of machinery field and in life, when outer-hexagonal bolts or soket head cap screw are because being used for multiple times, and make
Become fillet at screw head abrasion, common wrench can not use at this time, it may appear that slipping phenomenon can not back-out and screw head is broken
It can not all be screwed out using common wrench.
Utility model content：
The purpose of this utility model is exactly to solve existing issue, and providing a kind of can both back-out due to screw head is worn
The screw that can not be screwed out can also back-out the multipurpose wrench for the screw that can not be screwed out because screw head is broken.
The technology solution of the utility model is as follows：
A kind of multipurpose wrench, including jaw, jaw upper end medial surface form inverted V-shaped notch, and lower end is vertical
It is fixed with connecting rod, installation screw is formed inside the connecting rod, the installation screw runs through connecting rod and jaw lower end, institute
The top for stating installation screw is inserted with mobile bar, and lower part is bolted with lead screw, and the top surface of the mobile bar forms blade and thereon
Portion is bolted with withstanding tight block, and the top surface of the withstanding tight block forms V-notch.
Preferably, the angle of the V-notch is 120 °
Preferably, the lower end of the lead screw is fixed with round platform, the radial direction of the round platform forms through-hole, in the through-hole
It is inserted with handle.
Preferably, the jaw and the connecting rod can be integrally formed.
Preferably, the bottom surface of the withstanding tight block forms the screw hole being spirally connected with mobile bar.
The beneficial effects of the utility model are：By the withstanding tight block with V-notch that is spirally connected in mobile bar, coordinate leading screw
It screws in the screw head of outer-hexagonal bolts can be clamped and back-out, remove the withstanding tight block in mobile bar, cooperation leading screw screws in, and blade is made to contradict
The cylindrical wall or screw rod cylindrical wall of soket head cap screw screw head, you can back-out soket head cap screw or be broken the screw of screw head.

Specific implementation mode：
As shown in figures 1 to 6, multipurpose wrench, including jaw 1,1 upper end medial surface of the jaw form inverted V-shaped notch,
Its lower end is vertically fixed connecting rod 2, installation screw 3 is formed inside the connecting rod 2, the installation screw 3 is through connection
The top of 1 lower end of bar 2 and jaw, the installation screw 3 is inserted with mobile bar 4, and lower part is bolted with lead screw 5, the mobile bar 4
Top surface forms blade 6 and upper part is bolted with withstanding tight block 7, and the top surface of the withstanding tight block 7 forms V-notch.
Specifically, the angle of the V-notch is 120 °, this setting can make V-notch more preferably be bonded outer-hexagonal bolts
Screw head, increase clamping force.
Specifically, the lower end of the lead screw 5 is fixed with round platform 8, and the radial direction of the round platform 8 forms through-hole, the through-hole
In be inserted with handle 9, this setting facilitates leading screw to screw or screw out connecting rod 2.
Specifically, the jaw 1 and the connecting rod 2 can be integrally formed, this setting improves the whole strong of spanner
Degree.
Specifically, the bottom surface of the withstanding tight block 7 forms the screw hole being spirally connected with mobile bar 4, this setting is by withstanding tight block 7 and moves
Lever 4 makes detachable structure, not only saves cost, and accelerates to cope with the replacement speed of different screws.
By the withstanding tight block 7 with V-notch that is spirally connected in mobile bar 4, leading screw screws in connecting rod 2 and ejects mobile bar 4, until
The screw head of outer-hexagonal bolts is clamped in jaw 1 by withstanding tight block 7, and rotating spanner outer-hexagonal bolts are back-outed；It screws off in mobile bar 4
Withstanding tight block 7, leading screw screw in connecting rod 2 and eject mobile bar 4, and blade 6 is made to hold out against outside cylindrical wall or the screw rod of soket head cap screw screw head
Circle wall, the length direction of blade 6 must be consistent with the thickness direction of spanner during holding out against, and can just prevent spanner from skidding in this way, most
Rotating spanner back-outs soket head cap screw or is broken the screw of screw head afterwards.
The above is only the preferred embodiment of the present invention, and those of ordinary skill in the art are not making creativeness
The every other embodiment obtained under the premise of labour should all belong to the range of the utility model protection.
