[0002] Fasteners are a general term for a class of mechanical parts used to firmly connect two or more parts (or components) into a whole. Fasteners are also called standard parts in the market.

[0003] At present, most of the fasteners on the market use threaded connections to fix two workpieces. By rotating the fastener, the threaded groove and the threaded ring are threadedly connected to prevent the fastener from separating from the workpiece. In the specific use process, due to the influence of external vibrations and other factors, it is easy for the fastener to become loose from the workpiece, reducing the connection degree between the workpieces. Moreover, the existing anti-loose fasteners are troublesome to disassemble and install, require a long time, and cannot quickly adjust the fastener. Summary of the Utility Model

A fixed ring is fixedly installed at the bottom of the movable block. One side of the movable block is inserted with an auxiliary clamping block. And an upper limit ring is screwed on the top of the nut body. A lower limit ring is screwed outside the fixed ring at the bottom of the nut body.

[0007] When the movable block and the fastener body are inserted, a complete and continuous thread pattern can be formed in the middle parts of the movable block and the fastener body.

[0008] In addition, preferably, at both ends of the side of the movable block close to the insertion surface, T-shaped clamping blocks are symmetrically arranged. And at the position of the T-shaped clamping blocks on the side of the fastener body close to the splicing surface, through grooves are opened.

[0009] In addition, preferably, on the side of the auxiliary clamping block close to the T-shaped clamping block, a plurality of first clamping protrusions are fixedly installed at equal distances.
