Abstract

The utility model belongs to a two-way fast spanner. The utility model is characterized in that a spanner handle is matched with a square hole at the tail end of a worm rod, and the worm rod is movably fixed in a shell by at least two supporting tables, and rotary teeth the worm screw is engaged with a middle gear, and clearances are matched in long holes on the upper and the lower surfaces. The rear part of the middle gear is provided with a spring which is fixed in the shell, and the front side of the middle gear is meshed with a sleeve barrel gear, and clearances are matched on the upper and the lower surfaces of the shell; the inside of the sleeve barrel gear is a square hole and is matched with a sleeve pipe. The two-way fast spanner has multiple functions, and the spanner handle can axially rotate along a screw. The utility model is suitable for assembling and disassembling screws which is difficult to assembled and disassembled due to environmental limit. The utility model has the advantages of convenient operation, time saving and labor saving, has the function of one-way fast spanner without a spanner handle, and is suitable for being used in a repair trade.

Description

Two-way speeder wrench

This utility model relates to spanner, is the two-way speeder wrench that a kind of repairing trades is used.

At present, at the widely used spanner of repairing trades double offset ring spanner, shfting wrench and unidirectional speeder wrench are arranged, these spanners have individual common fault, all be to rotate and to work at screw or the same direction of rotation of nut, to affected by environment, when spanner can only enter to rotate, need earlier other parts to be pulled down, could use spanner then, not only bother but also lose time and manpower.

The purpose of this utility model provides a kind of two-way quick wrench that had not only kept unidirectional quick wrench characteristic but also can change the spanner direction of motion, can only rotate and to work at screw or the same direction of rotation of nut to solve existing spanner, to affected by environment, when spanner can only enter to rotate, need earlier other parts to be pulled down then and could be used, not only bother but also lose time and the manpower problem.

The purpose of this utility model is achieved in that this wrench is made up of handle and sleeve pipe.Handle matches with the interior square hole that worm screw is not held, worm screw is fixed in the housing by at least two platform activities, its front portion is revolved and is engaged with idler gear on the tooth, the idler gear matched in clearance is in the slotted hole of housing top and bottom, and its rear portion is provided with spring, and spring is fixed in the housing, the front side sleeve gear that has been meshed, the sleeve gear matched in clearance is square hole in the sleeve gear on the housing top and bottom, it matches with sleeve pipe.

Operation instruction: at first choose sleeve pipe and be inserted in the sleeve gear square hole, casing pipe sleeve is on screw or nut, come the back rotation body that encrusts, can realize the function of unidirectional quick wrench loading and unloading screw, body can not come back rotation if the surrounding environment restriction encrusts, and handle can be inserted worm screw and not hold in the square hole, the rotation handle, worm screw can drive sleeve gear by idler gear and rotate, and sleeve gear drives sleeve pipe and rotates, and can realize the screw loading and unloading.

This utility model compared with prior art has the following advantages: 1) handle can be along screw shaft to rotation, and is suitable especially to the loading and unloading that are difficult to load and unload screw because of ambient influnence, reduced trouble, saved time and manpower; 2 idler gear matched in clearance are at housing up and down in the slotted hole, and the rear portion is provided with spring, can realize the function of unidirectional speeder wrench; 3) the sleeve gear endoporus matches with sleeve pipe, can realize a wrench multifunctional, is suitable for the loading and unloading of all size model screw.

Be described further below in conjunction with accompanying drawing:
