Connecting rods are installed on both sides of the outer surface of the sleeve ring one. One ends of the two connecting rods are fixedly connected to the sleeve ring two. Sleeve rods are installed on one side of the two sleeve rings two. The two sleeve rods are sleeved outside the side rods. Arc plates are installed at one ends of the two sleeve rods. Two soft wheels are rotatably installed inside the two arc plates.

[0006] As a preferred technical solution of the utility model, the two soft wheels are made of rubber material and have wear-resistant coatings on their surfaces. A cylindrical part main body is clamped between the two groups of soft wheels.

[0007] As a preferred technical solution of the utility model, turning handles are installed at one ends of the two threaded rods located on the left side of the fixed frames. Two fixed grooves are opened on one side of the two fixed frames.

[0008] As a preferred technical solution of the present utility model, two groups of fixing structures are installed on both sides of the outer surface of the main body frame, and the two groups of fixing structures include two rotating shafts and two baffle plates.

[0024] Please refer to Figure 3-4, the two soft wheels 312 are made of rubber and have wear-resistant coatings on their surfaces. A cylindrical part body 4 is clamped between the two groups of soft wheels 312. At one end of the two threaded rods 32 located on the left side of the fixed frame 31, a turning handle 33 is installed, and two fixing grooves are provided on one side of the two fixed frames 31.

[0025] Please refer to Figure 1 and Figure 4 , on both sides of the outer surface of the main body frame 1, two groups of fixing structures 6 are installed. The two groups of fixing structures 6 include two rotating shafts 61 and two baffle plates 62. The two rotating shafts 61 are fixed on one side of the main body frame 1, and the two baffle plates 62 are fixedly connected to the main body frame 1.
