Claims (1)

[Scope of utility model registration request] A main body case 1 having a circular cavity 22; rotatably accommodated in the cavity 22 and having an axial hole 3;
a rotor 2 formed with a circular keyhole 3 having an L-shaped longitudinal section and a radial hole 3b; a main body case 1;
A stop plate 8 is fixed to the rotor rear end 6 protruding from the back side of the rotor; a key piece 51 is pivotally attached to the tip part by a transverse pivot 53, and the tip arc surface 54 of the key piece 51 is inserted into the key hole 3. When the key piece 51 comes into contact with the bottom surface 4, the key piece 51 rotates 90 degrees, and the vertical surface 5 formed on one side of the tip arc surface 54
5 is a cylindrical handle key 71 that engages with the inner surface 37 of the radial hole 3b;
5; a slider 65 that engages and disengages from a recess 58 provided in the handle key 71; the slider 65 is fitted into one half of the proximal end side of the handle key 71, is rotatable at a certain angle with respect to the handle key 71, and has a knob at the proximal end; Outer cylinder body 47 provided with 49
and; a spring 70 that urges the slider 65 to slide in the direction of the key piece 51 ; a spring 70 that is pivotally connected to the base end of the slider 65 by a transverse pivot 67 and protrudes from an axial elongated hole 72 of the handle key 71; A folding type insertion/extraction handle device comprising a locking plate 68 that is inserted into an axial groove 69 of an outer cylinder body 47 and engages and disengages from a circumferential notch 73 on the inner surface of the axial groove 69.
