[0026] Please refer to Figure 4 In order to stably fix the terminal box 1, the mounting mechanism 4 in the embodiment includes a fixed box 401 fixed on the left and right sides of the terminal box 1, a screw rod 402 rotatably connected between the inner top wall and the inner bottom wall of the fixed box 401 through a bearing, an activity plate 403 threadedly connected to the outer surface of the screw rod 402, limit insertion rods 404 fixed to the left and right ends of the lower surface of the activity plate 403, and through holes 405 formed in the left and right ends of the inner bottom wall of the fixed box 401. If the terminal box 1 is fixed in the ground, the screw rod 402 can be rotated, the rotation of the screw rod 402 causes the activity plate 403 threadedly connected to the surface of the screw rod 402 to move linearly under the action of the limiting block and the limiting groove, the movement of the activity plate 403 drives the two limit insertion rods 404 fixed to the lower surface of the activity plate 403 to move downward, so that the limit insertion rods 404 enter the ground through the through holes 405, which can ensure the stability of the fixation of the terminal box 1. The left and right ends of the lower surface of the terminal box 1 are fixed with two suction cups 406. If the terminal box 1 is fixed on the desktop, the terminal box 1 can be pressed downward, so that the four suction cups 406 on the lower surface of the terminal box 1 are adsorbed on the desktop, thereby completing the fixation of the terminal box 1.

[0033] (2) If the terminal box 1 is fixed in the ground, the screw rod 402 can be rotated, the rotation of the screw rod 402 makes the movable plate 403 threaded on the surface of the screw rod 402 move linearly under the action of the limiting block and the limiting groove, the movement of the movable plate 403 drives the two limiting inserting rods 404 fixed on the lower surface of the movable plate 403 to move downward, the limiting inserting rods 404 enter the ground through the through holes 405, the stability of the fixation of the terminal box 1 can be ensured, if the terminal box 1 is fixed on the desktop, the terminal box 1 can be pressed downward, the four suction cups 406 on the lower surface of the terminal box 1 are adsorbed on the desktop, and the fixation of the terminal box 1 is completed.
