[0023] Specifically, the clamping assembly 10 includes a reset spring 101, a cavity 102, a movable cavity 103, an L-shaped rod 104, a clamping groove 107 and a clamping rod 108. The cavity 102 is provided on the side wall of the insertion rod 7, and the clamping rod 108 is inserted into the cavity 102. The reset spring 101 is connected between the cavity 102 and the clamping rod 108. One end of the clamping rod 108 is connected to the L-shaped rod 104. The movable cavity 103 is provided on the side wall of the cavity 102 and at a position corresponding to the L-shaped rod 104. The clamping groove 107 is provided inside the second convex strip 3 and at a position corresponding to the clamping rod 108.

[0024] By adopting the above technical solution, the L-shaped rod 104 is pressed into the movable cavity 103, and the L-shaped rod 104 moves to drive the clamping rod 108 to move and be collected into the cavity 102, and the clamping rod 108 moves to squeeze the reset spring 101, and then the insertion rod 7 is aligned with the position of the slot 8, and the two outer magnetic ring bodies 1 are moved toward the inner magnetic ring body 4. The movement of the outer magnetic ring body 1 drives the first convex strip 2 to move, and the movement of the first convex strip 2 drives the insertion rod 7 to move and be inserted into the slot 8. When the insertion rod 7 completely enters the slot 8, the L-shaped rod 104 is released, and the reset spring 101 loses the external force and returns to its original state, driving the clamping rod 108 to move and be inserted into the clamping groove 107. Under the action of the clamping rod 108 and the clamping groove 107, the insertion rod 7 and the second convex strip 3 can be clamped and fixed, and then the first convex strip 2 and the second convex strip 3 can be clamped and fixed, thereby ensuring the stability of the connection between the two outer magnetic ring bodies 1 and the inner magnetic ring body 4.

[0025] Specifically, a guide slider is connected to the side of the clamping rod 108 away from the L-shaped rod 104, and a guide slot is provided on the side wall of the cavity 102 at a position corresponding to the guide slider.

[0026] By adopting the above technical solution, the movement of the clamping rod 108 drives the guide slider to move inside the guide slot. Under the sliding cooperation of the guide slider and the guide slot, a guiding effect can be provided for the movement of the clamping rod 108, thereby improving the stability of the movement of the clamping rod 108.

[0027] Specifically, the clamping assembly 10 further includes a magnetic block 105 and a top plate 106. The top plate 106 is connected to the side wall of the second convex strip 3, and the magnetic block 105 is connected to the side where the L-shaped rod 104 and the top plate 106 are close to each other.

[0028] By adopting the above technical solution, the reset spring 101 can drive the clamping rod 108 to move during the reset process, and at the same time, it can drive the L-shaped rod 104 to move toward the top plate 106, so that the two magnetic blocks 105 on the top plate 106 and the L-shaped rod 104 are close to each other and adsorbed and fixed, ensuring the stability of the placement of the L-shaped rod 104, and then ensuring the clamping and fixing effect of the clamping rod 108.

[0029] When the present embodiment is used, the L-shaped rod 104 is pressed into the movable cavity 103, and the L-shaped rod 104 moves to drive the clamping rod 108 to move and be collected into the cavity 102, and the clamping rod 108 moves to squeeze the reset spring 101, and then the insertion rod 7 is aligned with the position of the slot 8, and the two outer magnetic ring bodies 1 are moved toward the inner magnetic ring body 4. The movement of the outer magnetic ring body 1 drives the first convex strip 2 to move, and the movement of the first convex strip 2 drives the insertion rod 7 to move and be inserted into the slot 8. When the insertion rod 7 completely enters the slot 8, the L-shaped rod 104 is released, and the reset spring 101 loses the external force. By restoring the original appearance, the clamping rod 108 is driven to move and plug into the clamping groove 107. At the same time, the L-shaped rod 104 can be driven to move toward the top plate 106, so that the two magnetic blocks 105 on the top plate 106 and the L-shaped rod 104 are close to each other and adsorbed and fixed, ensuring the stability of the placement of the L-shaped rod 104. Under the action of the clamping rod 108 and the clamping groove 107, the insertion rod 7 and the second convex strip 3 can be clamped and fixed, and then the first convex strip 2 and the second convex strip 3 can be clamped and fixed, ensuring the stability of the connection between the two outer magnetic ring bodies 1 and the inner magnetic ring body 4;

[0034] When the present embodiment is used, the first coil 5 and the second coil 6 are sleeved onto the side walls of the inner magnetic ring body 4 and the outer magnetic ring body 1. When the first coil 5, the second coil 6 or the operator's hand contacts the movable plate 93, the movable plate 93 moves due to the collision. The movement of the movable plate 93 drives the movable rod 94 to move into the movable groove 97 and the guide rod 92 to move into the guide hole 91. During the movement of the movable rod 94, the connecting spring 96 is squeezed to prevent the first coil 5, the second coil 6 or the operator's hand from directly contacting the first convex strip 2 or the second convex strip 3. At the same time, under the action of the rubber pad 95, the first coil 5, the second coil 6 or the operator's hand can be prevented from directly contacting the movable plate 93, thereby preventing the first coil 5 and the second coil 6 from being worn, and at the same time, preventing the operator's hand from being worn.

During the movement of the movable rod 94, the connecting spring 96 is squeezed to prevent the first coil 5, the second coil 6 or the operator's hand from directly contacting the first convex strip 2 or the second convex strip 3. At the same time, under the action of the rubber pad 95, the first coil 5, the second coil 6 or the operator's hand can be prevented from directly contacting the movable plate 93, thereby preventing the first coil 5 and the second coil 6 from being worn. At the same time, the wear of the operator's hand can be avoided, and then the L-shaped rod 104 is pressed into the movable cavity 103, and the L-shaped rod 104 moves to drive the clamping rod 108 to move and be collected. When the rod 7 is completely inserted into the slot 8, the L-shaped rod 104 is released, the reset spring 101 loses the external force and returns to its original state, driving the clamping rod 108 to move and plug into the clamping slot 1. 07, at the same time, the L-shaped rod 104 can be driven to move toward the top plate 106, so that the two magnetic blocks 105 on the top plate 106 and the L-shaped rod 104 are close to each other and adsorbed and fixed, ensuring the stability of the placement of the L-shaped rod 104. Under the action of the clamping rod 108 and the clamping groove 107, the insertion rod 7 and the second ridge 3 can be clamped and fixed, and then the first ridge 2 and the second ridge 3 can be clamped and fixed, ensuring the stability of the connection between the two outer magnetic ring bodies 1 and the inner magnetic ring body 4.
