Description
Technical field
The utility model relates to machine tool, specifically a kind ofly exempts to withdraw from speeder wrench.
Background technology
The spanner that fastening and pine is unloaded (hereinafter to be referred as " workpiece ") usefulness such as screw, nut, pipe is widely used a kind of in the instrument.Existing monkey wrench, fork spanner, double offset ring spanner, box spanner need transposition repeatedly in the process of degree of tightness workpiece, be about to spanner and extract out, its bayonet socket alignment pieces are inserted after the anglec of rotation again, waste time and energy so repeatedly.When workpiece was in the position that is difficult for watching, the spanner bayonet socket just was difficult to alignment pieces more.Though ratchet spanner, pipe spanner need not contraposition repeatedly when the degree of tightness workpiece, the workpiece periphery must have bigger space to use with the top.
Summary of the invention
The purpose of this utility model provide a kind of can directly be stuck on the workpiece in use pull back and forth, time saving and energy saving, rapidly and efficiently exempt to withdraw from speeder wrench.
The technical solution of the utility model is: exempt to withdraw from speeder wrench and comprise handle and driving end, it is characterized in that driving end is made of the active card of band dop, the fixedly card and the triangle locking tongue of band dop, active card is crossed straight pin with fixing cartoon and is connected, fixing card connects by straight pin with handle, the locking tongue places between active card, fixing card and the handle head, and three faces (A, B, C) of locking tongue contact with three faces on the handle head with active card, fixing card respectively.
Feature of the present utility model also is in active card and handle edge one spring leaf to be housed.
Each member of spanner of the present utility model can be by self axle center and workpiece axle center back and forth and the composite rotating motion, guarantees effective transferring power between each member and the self-locking and the locking that produce power.Need not leave when making it to operate working substance the axle center and can suitable repeatedly, counterclockwise motion, different above-mentioned conventional spanner by stuck and repeatedly contraposition come complete operation, and possess the function of use and the characteristic of existing similar tools.Spanner of the present utility model is in use saved time than existing spanner, and efficient can be enhanced about more than once.Particularly be difficult for seeing the convenient, fast and safety of Cha Shiyou sense in work high above the ground and workpiece.
