[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a first annular groove 14 is provided on the front of the shell 1, and a turntable 15 is rotatably connected to the back of the inner cavity of the shell 1 through a bearing, and a handle 16 is bolted to the front of the turntable 15 through the first annular groove 14, and a first gear 17 is bolted to the back of the turntable 15. A second gear 18 is bolted to the front of the surface of the second rotating rod 5, and the surface of the first gear 17 is meshed with the surface of the second gear 18, so that the user can drive the turntable 15 in the inner cavity of the shell 1 to rotate through the handle 16. When the turntable 15 rotates, it will drive the first gear 17 to rotate, and the rotation of the first gear 17 will synchronously drive the second gear 18 to rotate, and then the second gear 18 drives the second rotating rod 5 to rotate.

[0026] like Figure 2 and Figure 3 As shown, a driven wheel 19 is bolted to the surface of the third rotating rod 9, a driving wheel 20 is bolted to the rear of the surface of the second rotating rod 5, and chains 21 are meshed on the surfaces of the driven wheel 19 and the driving wheel 20. When the second rotating rod 5 rotates, the driven wheel 19 is driven to rotate through the driving wheel 20 and the chain 21, and finally the third rotating rod 9 and the reciprocating screw 10 rotate synchronously.
