Description

Technical Field

[0001] The utility model relates to the field of self-locking devices, in particular to an automatic reciprocating telescopic self-locking mechanism. Background Art

[0002] In the field of mechanical design, it is often necessary to quickly position and lock one component to another, and the locking must be stable and reliable. Most self-locking mechanisms in current products rely on pins and sockets in the mechanism to achieve self-locking. The self-locking mechanism uses the elasticity of the spring, and the pin can be quickly and elastically inserted into the socket to complete the self-locking, expand into place, and reliably lock. However, this mechanism requires the operator to manually clamp the compression spring for assembly; the operator needs to adjust it back and forth, which is inefficient. Finally, during the assembly process, the operator may not compress the spring into place, and the spring may rebound, which may cause injury to the operator or damage to the product. This poses a certain safety hazard. Therefore, an automatic reciprocating self-locking mechanism is proposed. Utility Model Content
