The fixing ring 10 and the adjacent side of the T-block 8 are fixedly connected with the same spring 11. By setting the spring 11, the spring 11 can squeeze the fixing ring 10, thereby driving the fixing column 9 to be stuck in the corresponding fixing groove 6, which is convenient for locking the position of the T-block 8 and ensuring the stable use of the device. The spring 11 is slidably connected to the outside of the fixing column 9.

[0026] A connecting block 12 is fixedly connected inside the second housing 2, and a partition 13 is fixedly connected to the top of the connecting block 12. By providing the partition 13, the partition 13 can block the coil winding, facilitating the stable winding of the coil;

[0027] A plurality of limiting grooves 14 are formed through the top of the partition 13. By providing the limiting grooves 14, the limiting grooves 14 cooperate with the limiting column 7 to avoid the limiting column 7 from being offset and stuck during movement, thereby ensuring the stable movement of the limiting column 7.

[0028] The limiting column 7 is slidably connected in the corresponding limiting groove 14, and a mounting groove 15 is provided in the connecting block 12. The second housing 2 is connected to the partition plate 13 through the mounting groove 15. The mounting groove 15 is square in shape. The bottom of the fixing column 9 is slidably connected in the corresponding fixing groove 6. The bottom of the T-block 8 is slidably connected in the T-slot 5. By providing the T-slot 5, the T-slot 5 can support the T-block 8 to avoid the displacement and falling during the movement, thereby ensuring the stable movement of the T-block 8.

[0029] Two baffles 16 are provided outside the corresponding limiting column 7 . The baffles 16 are circular in shape and abut against the top and bottom of the corresponding arc-shaped groove 4 , respectively.
