Description

A kind of Multifunction self-locking spanner
Technical field
The present invention relates to a kind of aid, more particularly to a kind of Multifunction self-locking spanner.
Background technology
Traditional spanner can only twist hex nut, tetragonal nut, can not twist tubular articles and other shapes of nut.Work as spiral shell When mother is got rusty, because the active force of spanner is inadequate, often leading to nut can not be unscrewed, and have the possibility of slippage, can also damage Nut profile.And traditional spanner, after a nutting is completed, it is difficult to generally require a spanner and taken from nut to reset operation Go out, then return blocks nut again, repeats nutting action.Sought in addition, conventional spanner need to adjust worm gear repeatedly when twisting thing Look for and pull a mouthful extended distance, and in clamping repeatedly, pull mouth and also easily loosen, such operate brings very big difficulty to operation. And pipe wrench is mainly used in twisting tube, because pipe wrench is heavier, and pipe wrench is two-sided all with teeth, very big to the damage that is screwed thing, because The use range of this pipe wrench is restricted.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of Multifunction self-locking spanner, and the spanner can not only Quick fastening Gu hexagonal, tetragonal nut, additionally it is possible to lock tube, and can also be used as pliers.
To achieve the above object, the present invention provides following technical scheme:A kind of Multifunction self-locking spanner, including handle, The handle includes two first handles and second handle being rotatablely connected mutually, is respectively equipped with the top of first and second handle First and second clamping part, first retaining part in the top of second handle, the second retaining part in the top of first handle, First clamping part includes vertical fixed claw and the slider I being located on fixed claw, the side side of the fixed claw inwardly Elliptoid chute I is vertically provided with face, the top and bottom of slider I are equipped with the prevention slided in chute I Block, slider I are slidably connected with fixed claw by stoping block, and the side of the fixed claw is provided with through hole at bottom, in through hole Installation one prevents the distance between bolt, the bottom of the through hole and fixed claw from being more than or equal to the prevention positioned at slider I bottom The length of block, the clamping face of the slider I include top half and the latter half, and its top half is provided with sawtooth diagonally downward I, the latter half is plane, and slider I section is in pentagon, and flex point is provided between its top half and the latter half, and flex point is outside Protrusion;Second clamping part includes movable claw and the horizontal chute II being located at the top of first handle, and movable claw passes through fixation The sliding block II and chute II for being located at movable claw bottom are slidably connected, and the top of the clamping face of movable claw is provided with perpendicular to activity claw clip The sawtooth II in face is held, the latter half of slider I clamping face is parallel with the clamping face of movable claw, and the bottom of the sliding block II is provided with snail Bar, and the bottom of chute II is provided with the worm screw groove for accommodating worm screw, the top of first handle is in the position at the bottom of chute II Provided with the through hole through both sides at the top of first handle, and the bottom of the centre of through hole and chute II connects, and turns in through hole One worm gear of dynamic connection, worm and wheel coordinate.
Preferably, the section of chute II is square, and the top of chute II is provided with the length being connected as a single entity with the inwall of chute II Strip bulge, the sliding block II coordinate with chute II, and its section is convex.
Preferably, first and second handle in the edge of a knife that is respectively arranged below with of rotating joint, work in coordination by two edges of a knife.
Preferably, the edge of through hole is equipped with chamfering.
Using above-mentioned technical proposal, when clamp nut or tube, due to the clamping face of the slider I of the first clamping part Top half is provided with sawtooth I diagonally downward, thus when clamping, prevents bolt from coordinating with stoping block, and slider I is limited The movable claw of position, sawtooth and the second clamping part coordinates, locked to nut or tube, the phenomenon skidded is avoided, when the present invention exists Carry out return when, it is only necessary to opposite direction rotation the present invention, so as to ensure the present invention can quickly, easily to nut or pipe Shape thing is fastened.And the present invention is due to provided with first and second handle, and two handles rotate mutually link, and slider I only has The first half sets up sawtooth I separately, and the latter half is plane, thus the present invention is also used as shfting wrench use, is pulled when as the survivor of a murder attempt Hand is clamped in use, can be put in object between the latter half of slider I clamping face and movable claw, avoids pressing from both sides bad object, And overcome a shortcomings that thing one is used.
