When the set heat shrink tube length is reached, the second stepping motor 60406 stops rotating, and the third cylinder 60404 extends to make the stop block 60403 press the heat shrink tube 60402. Then, the pneumatic scissors 60401 move to cut the heat shrink tube 60402. Finally, the second stepping motor 60406 drives the heat shrink tube 60402 clamped by the second clamping claw cylinder 60408 to move forward to complete the automatic sleeve on the right.
