The sides of the two conical tooth blocks 11 are fixedly sleeved with a connecting rod 14, and one end of the connecting rod 14 away from the conical tooth block 11 is fixedly connected to the side of the photodetector body 1 through a plurality of connecting rods 17. The periphery of the connecting rod 14 is fixedly connected with a convex rod 18, and the connecting rod 17 can make the connecting rod 14 and the photodetector body 1 rotate synchronously.

[0024] Example 2: Please refer to Figure 1 - Figure 4, based on Example 1, the limiting support assembly includes a first limiting ring 7, a second limiting ring 15 is arranged on the periphery of the first limiting ring 7, the first limiting ring 7 and the second limiting ring 15 are respectively arranged on both sides of the periphery of the connecting support rod 14, and the gap between the first limiting ring 7 and the second limiting ring 15 is the same as the diameter of the connecting support rod 14, so that the connecting support rod 14 can move between the first limiting ring 7 and the second limiting ring 15, and the first limiting ring 7 and the second limiting ring 15 can guide the rotation of the connecting support rod 14;

[0025] See also Figure 2 The inner wall of the first limiting ring 7 is fixedly connected with a plurality of first support rods 8, and one end of the first support rod 8 away from the first limiting ring 7 is fixedly connected to the outer wall of the bottom end of the photodetector body 1, and the first support rod 8 can realize the synchronous movement of the first limiting ring 7, the connecting rod 14 and the photodetector body 1;

[0026] See also Figure 4 , a plurality of second support rods 16 are fixedly connected to the outer wall of the second limiting ring 15, one end of the second support rod 16 away from the second limiting ring 15 is fixedly connected to the inner wall of the outer protective cover 4, and a part of the second limiting ring 15 is fixedly connected to the inside of the outer protective cover 4, thereby fixing the position of the second limiting ring 15, and at the same time, the top of the second limiting ring 15 contacts the bottom of the protruding rod 18, thereby limiting the height of the connecting support rod 14;

[0028] The working principle of the utility model is as follows: when the device needs to be used, the device must first be installed in a suitable position and fixed. If the receiving angle of the photoelectric detector body 1 needs to be adjusted during the use of the device, the motor inside the motor box 3 must be driven first. The rotation of the output shaft of the motor can drive the first rotating rod 12 to rotate. The rotation of the first rotating rod 12 can drive the conical gear disk 10 to rotate. The rotation of the conical gear disk 10 can make the two conical tooth blocks 11 at the top thereof mesh along the tooth grooves. Since the two conical tooth blocks 11 are fixedly connected by a synchronization rod 13, the two conical tooth blocks 11 can be meshed and moved synchronously. During the movement, the diameter distance between the two conical tooth blocks 11 remains unchanged. The rotation of the two conical tooth blocks 11 can drive the connecting support rod 14 to rotate. Since the connecting support rod 14 is connected to the photoelectric detector The detector bodies 1 are fixedly connected by a plurality of connecting rods 17, so that the photoelectric detector body 1 can achieve an angle adjustment effect under the action of the two conical gear blocks 11. At the same time, since the outer periphery of the connecting support rod 14 is wrapped by the first limiting ring 7 and the second limiting ring 15, the connecting support rod 14 can rotate in the space between the first limiting ring 7 and the second limiting ring 15, and one of the connecting rods 17 is located at the top of the first limiting ring 7, so it can support the weight of the photoelectric detector body 1. At the same time, a part of the outer wall of the second limiting ring 15 is fixedly connected to the inner wall of the outer protective cover 4, so it can support the photoelectric detector body 1, so that the photoelectric detector body 1 can achieve angle adjustment under the action of support, avoid the photoelectric detector body 1 being blocked by foreign objects when rotating, and improve the rotation effect of the photoelectric detector body 1 when the angle is adjusted.
