When providing the pin hole 12 for pivotally attaching the
Fixing half hole 15 provided in fixing block 15
a and the movable half hole 16 provided in the movable block 16
By the forward movement of the moving block 16 which moves back and forth, the movable half hole 16a is fixed onto the fixed half hole 15a to complete the pin hole 12, and by the backward movement of the moving block 16, the pin hole 12 is completed. The movable half-hole 16a is separated from the fixed half-hole 15a, and openings B of both half-holes 15a, 16a are opened in any of the circumferential surfaces near the upper 7c, lower 7a, and front 7b of the boom end 7, and the same The basic work device is configured such that the hanging pin 17 can be moved and fixed from the opening B and inserted between the two half-holes 15a and 16a.
