Description

Technical Field

[0001] The present invention belongs to the technical field of fasteners, and more specifically, relates to a multi-functional nut rod for a hand-held nut machine. Background Art

[0002] In the field of mechanical engineering, nuts are very common fasteners, which are often used in cooperation with bolts or screws; when in use, external force needs to be applied to tighten the nut to play a fastening role. In the prior art, a hook wrench is often used to perform the tightening operation. During the operation, the operator holds the hook wrench and tightens the nut manually. The manual operation has a large labor intensity and low operation efficiency. In addition, when tightening the nut manually, it is impossible to accurately control the tightening torque applied to the nut. The operator judges whether the nut is tightened by experience, and often there will be inaccurate pre-judgment, resulting in the nut not being tightened in place, or excessive force being applied, causing the threads to slip and damaging the nut. With the development of the mechanization and automation industries, a type of hand-held nut machine that can tighten nuts has emerged on the market. However, the nut rods of traditional hand-held nut machines are fixed to the motor handle by threads, which is not easy to replace in later use; in addition, when the hand-held nut machine tightens the nut, it is necessary to manually place the nut into the nut slot at the bottom of the nut rod, which is very inconvenient when a large number of nuts need to be tightened.

[0003] The utility model can play the role of facilitating the disassembly of the nut rod and sucking the nut. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the technical problems put forward in the above background art, and provide a multi-functional nut rod for a hand-held nut machine, achieving the effect of facilitating the disassembly of the nut rod and sucking the nut.
