A limiting mechanism 21 is installed on the top of the switch housing 4. An empty slot is provided on the top of the switch housing 4. A cover plate 22 is rotatably connected to the inner wall of the empty slot. The cover plate 22 can seal the limiting mechanism 21, the lifting block 19, the extension plate 14 and the slide slot 8.

[0028] The positioning mechanism 13 includes a positioning plate 131, an arc groove 132 and an arc plate 133. Both ends of the arc plate 133 are fixedly connected to the inner wall of the storage groove 11. The surface of the positioning plate 131 contacts the inner wall of the storage groove 11.

When the staff moves the fixed plate 172, the guide rod 171 can drive the movable plate 18 to move. During this process, the fixed plate 172 can release the fixation of the auxiliary groove 15. The lifting block 19 moves with the movable plate 18 to squeeze the extension plate 14, thereby driving the positioning plate 131 to rotate through the extension plate 14, thereby releasing the contact between the positioning plate 131 and the positioning groove 3, so that the staff can quickly remove the switch housing 4 from the switch storage box 1.

The surface of the limiting rod 213 contacts the inner wall of the limiting groove 20. The position of the lifting block 19 can be limited by the setting of the limiting mechanism 21, thereby improving the stability of the position of the lifting block 19.

[0031] Working principle: When the staff needs to remove the switch housing 4, they can first open the cover plate 22, and then the staff can rotate the U-shaped rod 212, and the limit rod 213 rotates accordingly and releases the fixation of the lifting block 19, and then the staff can move the lifting block 19, and at this time the guide rod 171 moves accordingly to drive the fixing plate 172 to move, and the contact between the fixing plate 172 and the inner wall of the auxiliary groove 15 is released, and the lifting block 19 presses the bottom of the extension plate 14, and the positioning plate 131 can rotate and release the contact with the positioning groove 3, and accordingly the staff can move the switch housing 4 horizontally, and the switch housing 4 can be removed from the outside of the switch storage box 1;

[0032] When installing the switch casing 4, the staff can put the switch casing 4 on the surface of the switch storage box 1 and push the switch casing 4. Thereafter, under the action of the elastic force of the tension spring, the positioning plate 131 and the positioning slot 3 can be used in conjunction to limit the position of the switch casing 4. At the same time, the card block 7 enters the interior of the card slot 6 to fix the position of the switch casing 4. Finally, the staff can rotate the U-shaped rod 212 to limit the position of the lifting block 19 through the limit rod 213. At the same time, the fixing plate 172 can fix the position of the extension plate 14, and the staff can rotate the cover plate 22 to cover and shield the limiting mechanism 21, the fixing mechanism 17 and the slide groove 8.
