[0018] See also Figure 1-3The specific implementation of the locking mechanism for installing the bobbin 12 includes a positioning cylinder 1, a locking cylinder 2 and a rotating support 3. The rotating support 3 is arranged on the periphery of the positioning cylinder 1, and the bobbin 12 is installed on the rotating support 3 to facilitate the rotation of the bobbin 12; a spring 4 is arranged inside the positioning cylinder 1, and the spring 4 abuts against the locking cylinder 2. The upper end of the locking cylinder 2 protrudes along the positioning cylinder 1, which is convenient for pressing and releasing the locking cylinder 2, and the locking cylinder 2 bounces along the positioning cylinder 1; an opening 14 is arranged on the upper end wall of the positioning cylinder 1, and a spring 4 is arranged inside the opening 14. A ball 6 is provided, and the ball 6 is pressed between the opening 14 and the locking cylinder 2. The rotating support 3 and the ball 6 are arranged in sequence from bottom to top along the upper end of the positioning cylinder 1. The locking cylinder 2 pops up, and the ball 6 can be pressed between the opening 14 and the locking cylinder 2 to complete the work of limiting the rotating support 3. Since the bobbin 12 is installed on the rotating support 3, the axial movement of the bobbin 12 is also limited. Therefore, when the bobbin 12 rotates, the ball 6 will not generate friction to the bobbin 12 or the rotating support 3, thereby improving the rotation smoothness of the bobbin 12.

[0019] The locking and disassembling working process of the embodiment of the utility model is as follows: since the bobbin 12 is installed on the rotating support 3, the locking cylinder 2 pops up, and the ball 6 is pressed between the opening 14 and the locking cylinder 2, completing the work of locking the rotating support 3; pressing the locking cylinder 2, the ball 6 leaks out, completing the work of disassembling the rotating support 3.

[0020] Specifically, the bottom surface of the positioning cylinder 1 is provided with a plurality of positioning holes 13, which are circumferentially distributed below the positioning cylinder 1. The positioning holes 13 facilitate fixing the positioning cylinder 1 on the ingot body 11, thereby improving installation stability.

[0021] In this embodiment, the upper and lower ends of the locking cylinder 2 are respectively a protruding rod body and a slider body 8. The upper end of the slider body 8 abuts against the inner wall of the slot, and the protruding rod body protrudes along the upper end of the positioning cylinder 1 to facilitate pressing the protruding rod body.

[0022] Specifically, the diameter of the protruding rod body is smaller than the diameter of the tube opening of the positioning tube 1 , so that the protruding rod body can smoothly pass through the tube opening of the positioning tube 1 .

[0023] Specifically, the protruding rod body includes a pressing block 5 and a supporting block 9. The supporting block 9 is arranged between the pressing block 5 and the slider body 8. The diameter of the pressing block 5 is smaller than the diameter of the supporting block 9. The ball 6 is pressed between the surface of the supporting block 9 and the opening 14. When the pressing block 5 is pressed, the ball 6 is easy to leak out.

[0024] Specifically, the support block 9 and the pressing block 5 are connected by a chamfer 10 , so that when the pressing block 5 is pressed, the ball 6 can slide down smoothly.

[0025] In this embodiment, two rotating support members 3 are provided, and the two rotating support members 3 are vertically distributed below the balls 6 in sequence to improve the smoothness of the rotation of the bobbin 12 on the positioning cylinder 1 .
