Abstract

The invention discloses a fastener used for clamping an object. The fastener comprises a first clamping arm and a second clamping arm, wherein the first end of the first clamping arm is connected with the first end of the second clamping arm in a rotating mode, and a cavity used for containing the object when the object is clamped is formed between the first clamping arm and the second clamping arm. The first end of the first clamping arm is provided with at least one through hole communicated with the cavity. The first end of the second clamping arm is provided with at least one extending part, wherein the extending part penetrates through the through hole in the direction of facing the cavity and is wound around the edge of the through hole so as to form rotating connection, and the tail end of the extending part is located in the cavity and makes rubbing contact with the object when the fastener is used for clamping the object. The invention further discloses other embodiments and a manufacturing method of the fastener. In addition, the invention further discloses a self-locking device which can be used in the fastener for example.

Description

technical field [0001] The invention relates to the technical field of fastening devices, in particular to a fastener for clamping objects and a manufacturing method of the fastener. The fastener is, for example, a construction fastener used to build a scaffold. Background technique [0002] Fasteners, as a fastening device, are widely used in various fields for fastening, for example, they are used in the construction field to build scaffolding. In the prior art, the fastener generally includes a cover plate and a base (hereinafter collectively referred to as “clamp arms”), and a rotatable connection is formed between the cover plate and the base through a pin shaft. [0003] Existing fasteners generally include fasteners made by casting and fasteners formed by hot forging. [0004] In the cast fastener, the through hole on the cover plate for the pin shaft to pass through and the through hole on the base for the pin shaft to pass through are both formed by a perforation ...
