A clamping mechanism 4 is provided on one side of the shell 1, and the clamping mechanism 4 includes a fixed plate 41, a No. 1 cylinder 42 is fixedly installed on one side of the fixed plate 41, a No. 1 rack 43 is fixedly installed on one end of the No. 1 cylinder 42, a gear 44 is meshed on the outer wall of the No. 1 rack 43, a No. 2 rack 45 is meshed on the outer wall of the gear 44, a fixed rod 46 is fixedly installed on one side of the No. 2 rack 45, a No. 2 cylinder 47 is fixedly installed on one end of the fixed rod 46, a No. 2 cylinder 47 is fixedly installed on one end of the No. 2 cylinder 47, a fixed seat 48 is fixedly installed on the inside of the fixed seat 48 49. A round table 410 is fixedly installed at one end of the No. 3 cylinder 49, and four groups of rubber blocks 411 are slidably connected to the inner wall of the fixed seat 48. One side of the four groups of rubber blocks 411 is fixedly installed with a No. 1 spring 412. One side of the fixed plate 41 is fixedly connected to the outer wall of the shell 1, one side of the No. 1 rack 43 is slidably connected to one side of the fixed plate 41, one side of the gear 44 is rotatably connected to one side of the fixed plate 41, one side of the No. 2 rack 45 is slidably connected to one side of the fixed plate 41, one side of the fixed rod 46 is arranged through the interior of the shell 1, the round table 410 is arranged inside the fixed seat 48, the four groups of No. 1 springs 412 are all fixedly connected to the inner wall of the fixed seat 48, and the outer wall of the round table 410 is in contact with the outer wall of the four groups of rubber blocks 411.

[0030] In this embodiment, when the reel 3 needs to be replaced, the scraper 65 moves to push the reel 3 out, and the reel 3 falls to the inner wall of the shell 1. The staff first starts the No. 1 cylinder 42, and then the No. 1 cylinder 42 drives the No. 1 rack 43 to move when it is extended and retracted. Further, the No. 1 rack 43 drives the gear 44 to rotate, and then the gear 44 drives the No. 2 rack 45 to move. Therefore, the No. 1 rack 43 and the No. 2 rack 45 both slide on one side of the fixed plate 41. Further, the No. 2 rack 45 drives the fixed rod 46 to move, and the fixed plate 41 is fixed.

Then the No. 3 cylinder 49 contracts, and the four groups of No. 1 springs 412 are extended, driving the four groups of rubber blocks 411 to move toward the center position, thereby realizing the replacement and installation of the reel 3. By setting the No. 2 cylinder 47 and cooperating with the four groups of rubber blocks 411 to clamp and place the reel 3, the reel 3 is prevented from being collided and squeezed during the process of moving from the special-shaped block 52 to the fixed roller 2.
