[0031] The main unit 100 includes a base plate 101. Two sets of support frames 102 are provided on the upper surface of the base plate 101. The upper surfaces of the support frames 102 are each provided with a lifting groove 105. The upper surfaces of the two sets of lifting grooves 105 are each provided with a piston rod body 103. The upper surface of the base plate 101 is provided with a sliding groove 104. The surface of one set of support frames 102 is slidably connected to the inner wall surface of the two sets of sliding grooves 104. The lower surface of the other set of support frames 102 is fixedly connected to the base plate 101. The distance between the two sets of support frames 102 is adjusted according to the length of the piston rod body 103.
[0032] The clamping unit 200 includes two sets of lifting rods 201 that are slidably connected to the inner wall surface of the lifting groove 105. The lower ends of the two sets of lifting rods 201 are both provided with a reset assembly 208. One side surface of the two sets of lifting rods 201 is fixedly connected to a rack plate 202. The upper ends of the two sets of lifting rods 201 are both fixedly connected to a support seat 203, and the inner wall surface of the support seat 203 is rotatably connected to two sets of rollers 204.

[0038] During use, one group of support frames 102 is pushed to move inside the slide groove 104, and the rotating rod 213 rotatably connected to the support frame 102 rotates inside the slide groove 104, so that the distance between the two groups of support frames 102 can be adjusted according to the length of the piston rod body 103. Then the piston rod body 103 is placed on the surface of the roller 1 204, so that the roller 1 204 is pushed to the lifting rod 201 through the support seat 203 and slides downward inside the lifting groove 105. The rack plate 1 202 fixedly connected to the lifting rod 201 drives the meshing gear 1 207a to rotate, and the rotating shaft 207b fixedly connected to the gear 1 207a drives the gear 2 207c to rotate, thereby making the rack plate 2 207d and the gear meshing with the gear 2 207c engage. The strip plate three 207e drives the clamping seat 205 to slide on the surface of the support frame 102 through the connecting plate 206, so that the clamping seat 205 slides in the direction of the lifting rod 201 and clamps the piston rod body 103. It can not only clamp piston rod bodies 103 of different sizes, but also rotate the piston rod body 103 under the action of roller one 204 and roller two 212. When the piston rod body 103 is taken out, the lifting rod 201 can move upward and reset under the elastic force of the spring 208c, and the rack plate one 202 fixedly connected to the lifting rod 201 drives the gear one 207a to rotate in the opposite direction, thereby causing the clamping seat 205 to slide in the opposite direction and expand on the surface of the support frame 102, so as to facilitate the clamping of the next group of piston rod bodies 103.
