Claims

[Scope of utility model registration request]

The handle body 4 at the other end of the drive shaft 1 to which the pinion gear 2 is fixed is provided with a concave portion 5 opening outward, and the inner peripheral surface of the concave portion 5 has an inner diameter. A plurality of locking protrusions 1B are provided in a radial manner, and grooves 20 are provided on the inner surface of the locking protrusions 1B. A space 19 is formed at a predetermined interval between the mating locking protrusions 18.
A star-shaped member 21 is rotatably pivoted to the other end, and a plurality of locking arms 22 protrude radially from the outer circumference of the star-shaped member 21. A small protrusion 23 is provided on the outer surface side, and when the star-shaped member 21 is placed inside the recess 5 of the handle body 4, the small protrusion 23 is attached to the locking protrusion 1.
Further, a resilient member 24 is interposed between the star-shaped member 21 and the handle body 4, so that the star-shaped member 21 and the drive shaft 1 are pushed outward. The engagement between the small protrusion 23 and the recessed part 20 is maintained by elastically biasing the small protrusion 23 in the opposite direction, and the star-shaped member 21 is manually rotated slightly to release the locking arm 22... . . . in the space section 19.
..., the star-shaped member 21 will protrude outward from the recessed part 5 due to the elastic urging force of the elastic member 24, and the drive shaft 1 will accordingly move outward. The J1 hoisting device is characterized in that it is configured so that the pinion gear 2 and the other gear 3 are disengaged from each other by sliding, and are placed in an idle rotation state.
