It consists of two stepped radii cylinders with threads matching the dimensions of the slotted nut.

The inner thread of the clip (4) is a one-way stop thread.

The diameter of the spring steel anchor rod (2) backing plate is larger than the inner diameter of the spring steel anchor rod (2) and smaller than the inner hole diameter of the anchor sleeve (3).

The high manganese pulling rod (1) penetrates the spring steel anchor rod (2) through the threaded end, and the grooved end face of the pipe body of the spring steel anchor rod (2) and the backing plate of the high manganese pulling rod (1) are installed during installation Contact with the inner side, push in the combination of the anchor sleeve (3), the PU cushion (5) and the clip (4) until the inner side of the backing plate of the spring steel anchor rod (2) and the connected member (8) fit together, and the pipe body The slotted part is squeezed and contracted by the clip, install the slotted nut (6) on the high manganese drawing rod (1), and use a hammer tool to lock the high manganese drawing rod (1) in place.

The material of the high manganese drawing rod (1) is one of carbon steel, low carbon composite alloy, medium carbon composite alloy and composite steel bar.

Beneficial effects of the patent: the present invention has simple structure, strong reliability, reasonable setting, and good locking performance. At the same time, the PU buffer pad is mainly used to reduce the resonance damage of the locking device and reduce noise to a large extent.
