Fastener

Abstract

The invention discloses a fastener, which comprises a head part (1), a rod part (2), a guide rod (3), a sliding shaft (4) and a retaining block (5), wherein the rod part (2) is connected with the head part and comprises two extending parts (21) and a hollow part (22), each extending part is provided with a containing part (211), the guide rod protrudes into a through hole (11), extends into the hollow part, and can do axial movement through the operation by an operator, the two ends of the sliding shaft are contained in the containing parts and can move together with the guide rod, and the retaining block is rotationally arranged on the sliding shaft, and rotates from the first position to the second position under the action of gravity. In the first position, the retaining block can penetrate through a mounting hole together with the rod part. In the second position, the retaining block is locked on a to-be-connected part through the operation by the operator at the side of the head part. The fastener has the advantages that the to-be-connected part can be clamped at the two sides of the to-be-connected part, and the installation is only needed at one side of the to-be-connected part.

Description

technical field [0001] The present invention relates to mechanical parts, in particular, to a fastener. Background technique [0002] Fasteners are mechanical parts used to fasten two or more parts (or components) into a whole, usually including bolts, studs, screws, nuts, etc. Among them, the bolt connection formed by the mutual cooperation of bolts and nuts is widely used in various mechanical equipment as a reliable connection method. When bolting two parts to be connected, firstly, the bolt needs to be passed through the installation hole from one side of the part to be connected, so that the nut is against the part to be connected and the bolt is kept still, and then from the other side of the part to be connected One side tightens the nut onto the threaded rod. [0003] The above operations need to be carried out on both sides of the parts to be connected, and when the area of ​​the parts to be connected is large, one person cannot complete the above operations indep...
