摘要
The present invention relates to a handle attachment device for a crank lifter, in which a crank arm (1) is formed in opposite directions at both ends of a main shaft (X) provided horizontally in a main body (B) of a crank lifter. The crank arm 1 is provided at its distal end with a shaft 6 rotatably mounted with a shaft bolt 7 together with a plurality of bearings b and a support ring 3 of the handle 2 is rotatably mounted A fixing flange 5 is integrally formed on the outer circumferential surface of one side of the joined cover ring 4 so that the fixing flange 5 is fitted to the fitting portion and is detachably attached The attachment strength of the handle is further increased by the engagement of the attachment flange and the attachment portion so that the durability is improved and the crank movement can be performed more safely without any trouble.
