Abstract
Provided is a connection structure of an operation rod in which a connection object such as a tip tool can be easily attached to and detached from the operation rod in a relatively short time without causing a fixed state. The main body is inserted into the cylindrical operation rod on the tip side. An engagement pair is formed of an engagement part with a notch provided to the main body on a tip side and an engagement part with an engagement pin provided to a tip tool. An inner slider on which a recessed groove is formed in a circumferential direction is relatively slidably disposed to the main body on an inner diameter side. An outer slider is relatively slidably disposed to the main body on an outer diameter side, wherein an opposing recess which can oppose to the recessed grove is formed on the outer slider.
Claims6
A connection structure of an operation rod to connect the operation rod with a connection object by engaging an operation rod side engagement part of the operation rod with a connection object side engagement part of the connection object in a longitudinal direction of the operation rod, the connection structure of the operation rod comprising:
- a main body integrally formed with the operation rod side engagement part and extending in the longitudinal direction;
- a moving body of the operation rod, the moving body being movable in the longitudinal direction relative to the main body;
- and
- a floating piece loosely arranged in a through-hole provided in the main body to extend in a direction intersecting with the longitudinal direction,
- wherein the moving body includes a recessed part on a surface of the moving body facing the main body at a position where the through-hole is aligned when the moving body is in contact with the connection object side engagement part of the connection object in a state of engagement, in which a first end of the floating piece is fitted in the recessed part,
- wherein the moving body is provided in the main body and is urged toward a tip side end of the main body in a state that the moving body is not in contact with the connection object side engagement part.
