A round rod 17 is rotatably connected to the inside of the adjusting plate 13 via a shaft. A gear 18 is installed at one end of the round rod 17. A connecting rod 19 is installed at the other end of the round rod 17. Both ends of the connecting rod 19 are rotatably connected to a support rod 20 via a shaft. A clamping plate 21 is rotatably connected to the rear of the support rod 20 via a shaft. A T-shaped slider 22 is installed at the rear of the clamping plate 21. A rubber pad 23 is installed on one side of the clamping plate 21. A fixing plate 24 is installed at the front of the adjusting plate 13.

[0025] Specifically, it facilitates the placement of relays on the placement platform 2, impact detection is performed by the impact plate 6, and the position of the relays is restricted by the clamping plate 21.

[0026] Please see Figures 1 to 3 The position of the placement platform 2 corresponds to the position of the impact plate 6, and the position of the clamping plate 21 is higher than the position of the placement platform 2.

[0027] Specifically, the rectangular slider 10 plays a positioning and guiding role inside the rectangular groove, guiding the threaded ring block 9 and improving the stability of the relay's movement in the lateral direction.
