Abstract

The invention provides a wrench such as an assemble used for a nut and a bolt. The wrench is provided with a cylindrical cover which has a cap. A rotary lead hole of the cap is inserted with an earliest input axes arranging a mobile gear rotatablely. One end of the input axle is provided with an operating handle. The earliest input axle and the mobile gear respectively form an extrusive first and a second edge parts which respectively form a jog combined concavely and convexly. An elastic device is arranged between the cap and the first edge part and the outside of the earliest input axle and an earliest input axle stop control / removing device is also provided. The arrangement of the inclined angle of the concave and convex part, the compressed force of the elastic device and the earliest input axle stop control / removing device ensuring sensing the complete screw state of the fixed nut rapidly and providing the wrench with the best convenience through the empty rotary state of the mobile gear not through vision when installing the fixed nut.

Description

technical field [0001] The present invention relates to wrench. A device for attaching or removing a fixing nut to an object, for example, in order to fix a tire wheel of a vehicle on a wheel hub, the fixing nut is installed on or separated from a variety of fixing screw shafts protruding from the hub. It is a wrench that provides the best convenience by quickly sensing the fully tightened state of the set nut by moving the idling state of the gear instead of visually when installing the set nut. Background technique [0002] Tighten or loosen the setscrew. The device for tightening or loosening the fixing screw when the tire wheel of the vehicle is fixed to the wheel hub generally uses a wrench, which can quickly tighten or loosen the fixing nut even with the smallest force, and it may be convenient for women or the elderly to use. This product has been patented in the United States (License Notice: No. 6,742,417, hereinafter referred to as "Online Licensed Technology"). ...

Problems solved by technology

In addition, the torque spring (torque spring) elastically supported between the inner wall surface of the gripping tube and the rod (rod) of the prior art can remain stable until the target nut is fully tightened, but compression occurs

On the contrary, after the target screw is fully tightened, the moving shaft can no longer rotate, so in this state, the torsion spring will rotate the handle with a greater counter force, so that the torsion spring can be compressed to the maximum, resulting in the phenomenon that the inner wall of the tube is too close to the outside of the rod

[0005] As a result, when the worker tightened the target screw, he had to check the compression degree of the torque spring (torque spring) one by one from the open part at the end of the clamp tube while rotating the handle, so it was difficult to perform the task of tightening the target screw.

Fully tighten the moving shaft and it can no longer rotate, so in this state, the torque spring will rotate the handle with a greater reaction force, so that the torque spring can be compressed to the maximum, so the direction of the end of the clamping tube cannot be kept consistent, and it often happens downwards , making it difficult for the staff to confirm the job
