In operation of the device, the rotary motor 1 rotates the eccentric adjuster 16 about the central axis of the adjusting disk 20. Because the eccentric amount exists between the connecting hole 19 of the eccentric adjuster 16 and the rotating axis of the adjusting disk 20, the rotation of the rotating motor 1 becomes eccentric rotation of the connecting hole 19, the first joint bearing 13 connected with the connecting hole 19 drives the connecting rod 12 connected with the connecting hole to reciprocate up and down, the connecting end of the L-shaped amplifying rod 7 and the connecting rod 12 is also driven to reciprocate up and down, the other end of the L-shaped amplifying rod 7 also reciprocates around the bearing at the connecting position of the L-shaped amplifying rod 7 and the bearing fixing plate 8 because the L-shaped amplifying rod 7 is a rigid rod, and then the connecting end of the connecting rod 6 connected with the L-shaped amplifying rod 7 reciprocates under the traction of the L-shaped amplifying rod 7, and the connecting rod 6 drives the transition block 5 connected with the other end to reciprocate linearly along the linear guide rail 4 on the side surface of the fixing plate 3.
