Abstract

The utility model provides a movable ratchet wrench, which aims to overcome the defects that the conventional ratchet wrench is complicated in structure and relatively high in production cost. The movable ratchet wrench comprises a handle, a worm, and a wrench opening consisting of a fixed jaw and a movable jaw, wherein the movable jaw slides along an included angle edge of the two jaws; the movable ratchet wrench further comprises a wedge and a return spring; a convex post is arranged on the lower surface of the wedge; a through hole is formed in the convex post; a groove which corresponds to the convex post in size and is used for the convex post to slide therein is formed in the movable jaw along a clamping inclined plane; a big head of the wedge faces to the wrench opening, is embedded into the groove and is connected with the movable jaw in a sliding way; the return spring is installed inside the through hole of the convex post; one end of the return spring is fixedly connected with the movable jaw; and the other end of the return spring is fixedly connected with the wedge. The movable ratchet wrench is simple in structure, can screw hexagonal nuts, and is applicable to an environment using the ratchet wrench.

Description

A kind of adjustable ratchet wrench
Technical field
The utility model relates to a kind of machine tool, relates in particular to a kind of adjustable ratchet wrench.
Background technology
Ratchet spanner is little because of its work pivot angle, easy to use, efficient is high and be widely used, can be used for rotating the bolt or the nut that place narrow or inaccessible position, one direction is fast with bolt or nut screwing clamping, in electronic product assembling and maintenance work, it all is one of indispensable instrument in the enroute repair kit of the engineering goods such as automobile, lathe.Though the ratchet spanner kind is many in the market, all be to twist cheese head screw, can not twist hex nut, and these ratchet wrench structures are complicated, production cost is higher.
The utility model content
The utility model has overcome the shortcoming that ratchet wrench structure of the prior art is complicated, production cost is higher, can not twist hex nut, and a kind of adjustable ratchet wrench is provided.
The utility model realizes that the technical scheme that goal of the invention adopts is: a kind of adjustable ratchet wrench, comprise handle, worm screw and pull mouth by what fixed jaw and movable jaw formed, movable jaw slides along the two jaw arms of angle, also comprise voussoir and back-moving spring, described voussoir lower surface is provided with projection, projection is provided with through hole, movable jaw is provided with corresponding with the projection size in order to the groove of projection in interior slip along seizing the inclined-plane on both sides by the arms, the voussoir major part is slidingly connected with movable jaw in pulling mouthful direction embedding groove, back-moving spring is installed in the through hole of projection, and back-moving spring one end is fixedly connected with movable jaw, the other end is fixedly connected with voussoir.
The beneficial effects of the utility model are: when turning clockwise hex nut, be installed in reaction force that voussoir on the movable jaw is subject to hex nut upwards, slide to the right, pulling mouth reduces gradually, closely clamp with hex nut, this moment, hex nut screwed, and counterclockwise gently lifted spanner, and voussoir skids off initial position downwards, left along the chute of movable jaw, pull a mouthful distance and become large, and can be threaded to the other plane of hex nut.So repeatedly, can realize the function of ratchet spanner, one direction is tightened hex nut fast continuously.Spanner structure of the present utility model is simple, and production cost is low, can twist hex nut.
The utility model will be further described below in conjunction with accompanying drawing and the specific embodiment.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is partial sectional view of the present utility model.
Fig. 4 is the partial enlarged drawing of Fig. 3.
In the accompanying drawing, 1 is that movable jaw, 1-1 are that pin, 1-2 are that groove, 2 is that voussoir, 2-1 are that projection, 2-2 are that through hole, 2-3 are that fixed jaw, 4 is that worm screw, 5 is that handle, 6 is back-moving spring for block, 3.
The specific embodiment
Shown in accompanying drawing 1,2,3,4, a kind of adjustable ratchet wrench of present embodiment, a kind of adjustable ratchet wrench comprises handle 5, worm screw 4 and pulls mouth by what fixed jaw 3 and movable jaw 1 formed, movable jaw 1 slides along the two jaw arms of angle, also comprises voussoir 2 and back-moving spring 6.Voussoir 2 lower surfaces are provided with projection 2-1, and the projection 2-1 of present embodiment is cylindrical projection, and projection 2-1 is provided with through hole 2-2, and through hole 2-2 is positioned at the centre of projection 2-1.For making things convenient for the clamping of 2 pairs of tubular articles of voussoir, be provided with the flank of tooth in the little head part of voussoir 2 upper surfaces, the flank of tooth and upper surface form angle.Movable jaw 1 is provided with correspondingly with projection 2-1 size in order to the groove 1-2 of projection 2-1 in interior slip along seizing the inclined-plane on both sides by the arms, and the groove 1-2 of present embodiment is cylinder shape groove.Voussoir 2 major parts are slidingly connected with movable jaw 1 in pulling mouthful direction embedding groove 1-2, and in whole sliding process, the upper surface of voussoir 2 is vertical with the two jaw arms of angle.Back-moving spring 6 is installed in the through hole 2-2 of projection 2-1, and back-moving spring 6 one ends are fixedly connected with movable jaw 1, the other end is fixedly connected with voussoir 2.In the present embodiment, the groove 1-2 root of movable jaw 1 namely is provided with the pin 1-1 that runs through movable jaw 1 both sides near two jaw arm of angle positions, and back-moving spring 6 one ends are fixedly connected with pin 1-1.The through hole 2-2 of projection 2-1 is provided with block 2-3 pulling mouthful end, and block 2-3 is fixed in the through hole 2-2, and back-moving spring 6 other ends and the 2-3 that blocks a shot are fixedly connected with.
During actual the use, adjust the position of movable jaw 1 by worm screw 4, make the voussoir 2 that is installed on the movable jaw 1 and wait that twisting the hex nut outer surface contacts, the handle 5 that turns clockwise drives the hex nut rotation and tightens, voussoir 2 is subject to hex nut reaction force to the right along the groove 1-2 of movable jaw 1 upwards, slide to the right, pull mouth and reduce gradually, closely clamp with hex nut.After hex nut turns over certain angle, counterclockwise gently lift spanner, the reaction force that hex nut produces left voussoir 2, voussoir 2 skids off initial position downwards, left along the groove 1-2 of movable jaw 1, pull a mouthful distance and become large, be threaded to the other plane of hex nut, back-moving spring 6 will skid off the voussoir 2 of pulling mouth and reset.The hex nut that again turns clockwise, voussoir 2 is stressed upwards, slide to the right, closely clamps with hex nut, so repeatedly, can realize the function of ratchet spanner, and one direction is tightened hex nut fast continuously.
