The output end of the reduction box 8 is exposed above the box body 1, and the rotating rod 9 is fixed on the output end of the reduction box 8. The rotating rod 9 is driven to rotate by the motor 7, and the rotating rod 9 is provided with a vertically through-through A hole, a bending plate 10 is symmetrically provided at the lower end of the rotating rod 9, a nut 11 is movably connected between the bending plates 10, a screw 12 is threadedly connected in the nut 11, and an I-shaped cylinder 13 is provided at the upper end of the screw 12. The first hole passes through the rotating rod 9 from top to bottom, and the two bending plates 10 are symmetrically fixed at the lower end of the rotating rod 9. The nut 11 is surrounded between the bending rod and the rotating rod 9. The nut 11 can slide along the bending rod but cannot rotate. The screw 12 and the I-shaped cylinder 13 are fixed as a whole, and the screw 12 and the nut 11 are matched. The screw 12 is screwed downward into the nut 11, and the I-shaped cylinder 13 and the nut 11 are clamped on the rotating rod 9 to fix the position of the I-shaped cylinder 13.

The two thicker parts of the I-shaped cylinder 13 are located on the upper and lower sides of the reciprocating bar 17. A certain gap is left between the upper and lower thicker parts of the I-shaped cylinder 13 and the reciprocating bar 17 to provide a space for the screw 12 to rotate up and down. The circular motion of the I-shaped cylinder 13 will drive the reciprocating bar 17 to move back and forth left and right. The rack 18 is fixed at the left end of the reciprocating bar 17 and meshes with the gear 6. The gear 6 and the rotating shaft 3 are driven to rotate back and forth within a certain angle through the left and right reciprocating movement of the rack 18 to improve the monitoring range of the camera.

[0017] Specifically, wire holes connected up and down are provided on the rotating shaft 3, the rotating disk 4 and the box body 1, and a spring connection 19 is provided in the middle of the lower end of the camera body 5. The camera body 5 needs to be connected to the outside. Since the camera body 5 needs to rotate within a certain range, the connection is set at the bottom. The connection passes through the turntable 4, the rotating shaft 3 and the upper side wall of the box body 1. The reciprocating rotation of the camera body 5 can be neutralized by the spring connection 19, and then the connection of the camera body 5 and the motor 7 is combined into one and passes through the side wall of the box body 1 to connect to the outside.

[0020] Working principle: install or place the box body 1 to a suitable working position, and use the motor 7 to drive the rotating rod 9 on the output end of the reduction box 8 to rotate. The I-shaped cylinder 13 on the rotating rod 9 will rotate in a circle with the output end of the reduction box 8 as the axis. The rotation of the I-shaped cylinder 13 will drive the reciprocating bar 17 to move back and forth within a certain range. The rack 18 on the reciprocating bar 17 will drive the gear 6 to rotate back and forth within a certain range, thereby causing the rotating shaft 3, the turntable 4 and the camera body 5 to rotate back and forth to increase the monitoring range of the camera. The rotation amplitude range of the camera can be adjusted. Rotate the I-shaped cylinder 13 to loosen the screw 12, so that the I-shaped cylinder 13 and the nut 11 loosen the rotating rod 9, and then move the I-shaped cylinder 13 on the rotating rod 9 to adjust the rotation circle radius of the I-shaped cylinder 13, thereby adjusting the swing range of the camera.
