[0027] Embodiment 1:

[0028] A mounting hole 4 is provided on one side of the insulator body 1, and an annular groove 6 is provided on the arc surface of the inner wall of the mounting hole 4. The annular groove 6 can limit the vertical movement of the insert 2 in the insulator body 1. A sliding groove 5 is provided on one side of the insulator body 1 to position the insert 2 in the mounting hole 4. A through hole 8 is provided on the other side of the insulator body 1.

[0029] A limit block 9 is fixed on the arc surface of the insert 2, and a limit rod 11 is inserted into the limit block 9. The limit rod 11 can limit the circular motion of the insert 2 in the insulator body 1, and a pull ring 3 is fixed to one end of the limit rod 11.

[0030] Embodiment 2:

[0031] On the basis of the first embodiment, in order to realize the fixed connection of the three-phase insert 2 in the insulator body 1, a receiving groove 7 is provided on the arc surface of the inner wall of the through hole 8 to accommodate the spring 13, a limiting hole 10 is provided on the lower surface of the limit block 9, a baffle 12 is fixed on the arc surface of the limit rod 11, and a spring 13 is sleeved on the arc surface of the limit rod 11. Due to the elasticity of the spring 13, the reset of the spring 13 will push the baffle 12 to move in the receiving groove 7, so that the limit rod 11 is clamped in the limiting hole 10 through the through hole 8;

[0032] There are multiple groups of sliding grooves 5, which are circumferentially distributed on one side of the insulator body 1. There are multiple groups of limit blocks 9, which are circumferentially distributed on the arc surface of the insert 2. The limit blocks 9 correspond to the sliding grooves 5. The limit blocks 9 are clamped in the sliding grooves 5. The two are movably connected, which plays a positioning role in the movement of the insert 2 in the mounting hole 4.

[0033] There are multiple groups of through holes 8, which are circumferentially distributed on one side of the insulator body 1. There are multiple groups of limit rods 11, which are circumferentially distributed on the surface of the pull ring 3. The limit rods 11 correspond to the through holes 8, and the limit rods 11 are clamped in the through holes 8, and the two are movably connected.

[0034] The size of the receiving groove 7 is the same as that of the baffle 12, the size of the through hole 8 is the same as that of the limiting rod 11, and the size of the baffle 12 is larger than that of the limiting rod 11, and the baffle 12 corresponds to the receiving groove 7, and the baffle 12 is clamped in the receiving groove 7, and the two are movably connected, so the baffle 12 will not be separated from the receiving groove 7, and the limiting rod 11 will not be separated from the through hole 8;

[0035] There are multiple groups of limit holes 10, which are distributed circumferentially on the surface of the limit block 9. There are multiple groups of limit rods 11, which are distributed circumferentially on the surface of the pull ring 3. The limit rods 11 correspond to the limit holes 10. The limit rods 11 are clamped in the limit holes 10, and the two are movably connected. The limit rods 11 can limit the circular movement of the insert 2 in the insulator body 1.

[0036] In actual use, the limit block 9 is matched with the sliding groove 5, and then the insert 2 is clamped in the installation hole 4. The rotating insert 2 rotates in the annular groove 6. When the limit hole 10 corresponds to the through hole 8, the rotation of the insert 2 is stopped. At this time, due to the elasticity of the spring 13, the reset of the spring 13 will push the baffle 12 to move in the receiving groove 7, so that the limit rod 11 is clamped in the limit hole 10 through the through hole 8. At the same time, the pull ring 3 fits the surface of the insulator body 1, the annular groove 6 can limit the vertical movement of the insert 2 in the insulator body 1, and the limit rod 11 can limit the circular movement of the insert 2 in the insulator body 1, thereby realizing the fixed connection of the insert 2 in the insulator body 1.
