The mounting bracket 12 is provided with first holes 121, the first holes 121 penetrate the mounting bracket 12 in the thickness direction of the mounting bracket 12, and the first holes 121 are provided in one-to-one correspondence with the leveling screws 131. The first hole 121 is a light hole.

The leveling screw 131 has a head 1311 and a nail portion 1312 connected to the head 1311, and an outer peripheral surface of the nail portion 1312 is provided with external threads. The pin 1312 is threaded through the first hole 121 and is connected to the second hole 111, wherein the pin 1312 is not connected to the first hole 121. Based on this, the leveling screw 131 can be moved axially relative to the second hole 111 (i.e., in the direction of the central axis of the second hole 111) by rotating the leveling screw 131 to engage with the threads of the second hole 111 via the pin portion 1312, so that the distance between the head 1311 of the leveling screw 131 and the leveling platform 11 can be changed. Based on this, under the cooperation of the stabilizing structure 132, the area of the mounting bracket 12 corresponding to the leveling screw 131 can move relative to the leveling platform 11 until the head 1311 of the leveling screw 131 is positioned and stopped at the orifice of the first hole 121 far away from the second hole 111, and during this period, the movement of the mounting bracket 12 can be smoother due to the fact that the first hole 121 of the mounting bracket 12 is in non-threaded connection with the nail portion 1312 of the leveling screw 131, and the resistance to the movement of the mounting bracket 12 is smaller. Therefore, the gap between the mounting bracket 12 and the leveling platform 11 at the position where the leveling screw 131 is arranged can be conveniently, quickly and accurately adjusted.

The elastic member 1321 has elastic performance, and the elastic member 1321 is elastically abutted between the leveling platform 11 and the mounting bracket 12.

By adopting the scheme, when the leveling assembly 13 rotates the leveling screw 131 to adjust the distance between the head 1311 of the leveling screw 131 and the leveling platform 11, the elastic piece 1321 elastically propped between the leveling platform 11 and the mounting bracket 12 can apply elastic force to the area of the mounting bracket 12 corresponding to the leveling screw 131, so that the area of the mounting bracket 12 corresponding to the leveling screw 131 can automatically and smoothly move relative to the leveling platform 11 along with the leveling screw 131 until the mounting bracket 12 is matched with the positioning stop of the head 1311 of the leveling screw 131, thereby conveniently, quickly and accurately adjusting the gap between the mounting bracket 12 and the leveling platform 11 at the position where the leveling screw 131 is arranged, and conveniently, quickly and accurately adjusting the postures of the mounting bracket 12 and the sensor 20 relative to the leveling platform 11 according to requirements.
