CONNECTION STRUCTURE OF OPERATION ROD

Document Type and Number:

WIPO Patent Application WO/2019/017077

Kind Code:

A1

Abstract:

Provided is a connection structure of an operation rod in which objects to be connected, such as tip tools, can be easily attached and detached within a relatively short amount of time without causing a stuck state. A main body (2) is inserted in the distal side of a cylindrical operation rod (100). An engagement pair (9) is composed of: an engagement part (10) having a notch (10a) and provided on the distal side of the main body (2); and an engagement part (11) having an engagement pin (11a) and provided in a tip tool (101). On an inner diameter side of the main body (2), an inner slider (6) having a recessed groove (6a) formed along a circumferential direction is disposed so as to be capable of relative sliding. Also, on an outer diameter side of the main body (2), an outer slider (8) having a facing recessed portion (8a) capable of facing the recessed groove (6a) is disposed so as to be capable of relative sliding. In the main body (2), a through-hole (2a) is formed in the radial direction in the space between the inner and outer sliders (6, 8), and a lock member (4) is loosely inserted in the through-hole (2a). The lock member (4) is longer than the through-hole (2a), and at least one end on the inside or outside always protrudes from the main body (2).
