Has bone 44 '.
- the receiving bone 44 ′ and the parent bone 40 ′ are converged almost parallel to the middle rod 10 while the receiving bone 44 ′ bends the parent bone 40 ′.
- the center rod 10 is a telescopic type that also has a nested split pipe force, and a tip 11 is attached to the tip (upper end) and a hand 12 is attached to the base end (lower end).
- a repellent 13 for releasably locking the lower opening black 22 is provided at an intermediate portion near the tip (upper end).
- the master bone 40 ' is formed in a three-fold type consisting of an original master bone (also called a long bone) 41, a middle master bone 42, and a leading parent bone 43. Connected to the skeleton 44 'is a lower ligature 45 (also called a tie bar). The lower joint 45, together with the original master bone 41 and the middle master bone 42, forms a link mechanism that bends and stretches the master bone 40 'in conjunction with the vertical movement of the lower mouth crotch 22.
- an original master bone also called a long bone
