[0020] Please refer to Figures 1 to 5, one end of the pressing spring 8 is in pressing contact with the inner wall of the placement groove 5, and one end of the pressing spring 8 is in pressing contact with one end of the toothed plate 11. The monitoring camera 1 is slidably inserted into the base 4 through the insertion rod 2. The inclined end of the toothed plate 11 is clamped with the clamping groove 3 on the insertion rod 2. A section of the insertion rod 2 with the clamping groove 3 stays in the placement groove 5. Under the action of the pressing spring 8, the inclined end of the toothed plate 11 is clamped with the clamping groove 3 on the insertion rod 2, thereby positioning the insertion rod 2 and ensuring that the monitoring camera 1 is installed and fixed. A meshing groove 14 is formed on the lever 13, and the positioning block 16 is inserted into the meshing groove 14. After the connecting rod 15 is turned over, the positioning block 16 is clamped with the positioning groove 10 on the upper side of the gear 9. The lever 13 is sequentially passed through the bottom side wall of the base 4 and the positioning bolt 6, so that the end with the connecting rod 15 protrudes above the gear 9. Then the lever 13 is rotated, so that the connecting rod 15 at the upper end of the lever 13 unfolds under the action of centrifugal force. Then the lever 13 is pulled down, so that the side wall of the connecting rod 15 with the positioning block 16 contacts the upper side surface of the gear 9. Then the lever 13 is rotated so that the positioning block 16 on the connecting rod 15 is clamped with the positioning groove 10 on the upper side wall of the gear 9. After the positioning block 16 is clamped with the positioning groove 10, the lever 13 is rotated to drive the gear 9 to rotate. The gear 9 is in contact and meshes with the toothed plate 11. The toothed plate 11 is slidably inserted into the limiting rod 7 through the limiting groove 12. When the gear 9 rotates, it drives the toothed plate 11 to retract along with the limiting rod 7.

[0021] The monitoring device used in the weak current project in this utility model is composed of a monitoring camera 1 and a base 4. The base 4 is fixedly installed on the wall. An insertion rod 2 is installed at the bottom of the monitoring camera 1. A clamping groove 3 is formed on the periphery of the insertion rod 2, and the insertion rod 2 penetrates through the front end of the base 4 from top to bottom;

[0022] A placement groove 5 is formed in the base 4. A positioning bolt 6 is installed on the inner bottom side wall of the placement groove 5, and the middle part of the positioning bolt 6 is hollow. A gear 9 is rotationally clamped on the periphery of the positioning bolt 6. A limiting rod 7 is installed on the rear side wall of the placement groove 5. The limiting rod 7 is slidably sleeved with a toothed plate 11 with a limiting groove 12. A pressing spring 8 is also sleeved on the periphery of the limiting rod 7. One end of the pressing spring 8 is in pressing contact with one end of the toothed plate 11, and the other end is in pressing contact with the inner wall of the placement groove 5. After the toothed plate 11 is slidably sleeved with the limiting rod 7, the toothed plate 11 is in meshing contact with the gear 9. A positioning groove 10 is formed on the upper side of the gear 9. A lever 13 penetrates through the middle part of the positioning bolt 6. The upper end of the lever 13 is rotatably connected with a connecting rod 15. A positioning block 16 is installed on the inner side of the connecting rod 15 facing the lever 13. The positioning block 16 is inserted into the meshing groove 14 on the lever 13;

[0023] When installing the monitoring camera 1, insert the insertion rod 2 at the bottom of the monitoring camera 1 through the base 4, and the section of the insertion rod 2 with the card slot 3 stays in the placement groove 5. One end of the toothed plate 11 with an inclination angle is clamped with the card slot 3 on the insertion rod 2 under the action of the pressing spring 8, so as to position the insertion rod 2, ensuring that the monitoring camera 1 is installed and fixed. When it is necessary to disassemble the monitoring camera 1, a special lever 13 needs to be used. The upper end of the lever 13 is rotatably connected with a connecting rod 15, and a positioning block 16 is installed inside the connecting rod 15. Pass the lever 13 through the bottom side wall of the base 4 and the positioning bolt 6 in sequence, so that the end with the connecting rod 15 protrudes above the gear 9. Then rotate the lever 13, so that the connecting rod 15 at the upper end of the lever 13 unfolds under the action of centrifugal force. Then pull down the lever 13, so that the side wall of the connecting rod 15 with the positioning block 16 contacts the upper side of the gear 9. Then rotate the lever 13 so that the positioning block 16 on the connecting rod 15 is clamped with the positioning groove 10 on the upper side wall of the gear 9. When the positioning block 16 is clamped with the positioning groove 10, rotate the lever 13 to drive the gear 9 to rotate. The rotation of the gear 9 drives the toothed plate 11 to retract along with the limiting rod 7. When the toothed plate 11 disengages from the clamping with the card slot 3, the monitoring camera 1 with the insertion rod 2 can be pulled out, thus completing the disassembly of the monitoring camera 1. This structure is convenient for disassembly and assembly, and the setting of the lever 13 improves the safety of the monitoring camera 1 and reduces the possibility of the monitoring camera 1 being lost.
