Document Type and Number:
WIPO Patent Application WO/2021/004271
Kind Code:
A1
Abstract:
Disclosed is a locking structure of a telescopic rod member, the locking structure being used between an inner rod (1) and an outer rod (2) that are axially telescopic, wherein the outer rod (2) and the inner rod (1) are arranged in a mutually embedded manner. The locking structure comprises: a shaft sleeve (3) provided with a through hole (37), with the end portion of the side, connected to the inner rod (1), of the outer rod (2) being fixed in the through hole (37), the side wall of the shaft sleeve (3) being provided with a shaft hole (33) in communication with the through hole (37), and the shaft hole (33) facing the inner rod (1); and a spanner (4) rotationally connected to the shaft sleeve (3) at the shaft hole (33) and provided with a pressing block (43) accommodated in the shaft hole (33) and facing the inner rod (1). When the spanner (4) rotates in the circumferential direction along the shaft hole (33), the pressing block (43) presses on or is away from the inner rod (1); and the pressing block (43) presses on the inner rod (1), such that a state where the inner rod (1) and the outer rod (2) are telescopic can achieve locking, and the pressing block (43) is away from the inner rod (1), such that the state where the inner rod (1) and the outer rod (2) are telescopic can achieve unlocking. The structure is simple, and the application of force is balanced during locking and unlocking.
