The outer end of the limiting arm (26) is fixed with a positioning pin. The outer end of the positioning pin is fitted with a rotatably connected limiting slider (27). The limiting slider (27) is slidably engaged in the U-shaped channel steel (24).

6. The campus monitoring network control device according to claim 5, characterized in that: The upper and lower ends of the U-shaped vertical plate (1) are provided with a pair of first bolt holes, and an expansion bolt is inserted into each of the first bolt holes. The two ends of the U-shaped horizontal plate (2) and the positioning horizontal plate (21) are provided with second bolt holes, and a threaded locking bolt and a fixing nut are inserted into each pair of second bolt holes.

7. The control method for a campus monitoring network control device according to claim 6, characterized in that, Includes the following steps: Step 1: The monitoring camera (33) and the connecting seat (32) are designed as a single unit. The connecting seat (32) is placed in the center of the bottom surface of the fixed plate (31), and the inner end of the second L-shaped card plate (44) is pressed against the corresponding limiting slot. The second worm (36) is rotated, and the second worm (36) meshes and drives the second worm wheel (35), the linkage shaft, and the linkage gear (34) to rotate synchronously. Step 2: When the linkage gear (34) rotates, the linkage gear (34) meshes and drives the driven gear (37), driven shaft and eccentric pin to rotate. The eccentric pin and the elliptical ring (42) form a limiting effect, which in turn drives the elliptical ring (42) and the rectangular slide bar (41) to slide inward along the rectangular slide hole, causing the inner ends of the three first L-shaped plates (43) to abut against the corresponding limiting slots. Step 3: Simultaneously start a pair of micro motors (17). The motor shaft of the micro motor (17) drives the first worm (18) to rotate synchronously. The first worm (18) meshes with and drives the first worm wheel (15), the fixed shaft (12), and the fixed gear (13) to rotate. The fixed gear (13) meshes and rotates along the fixed rack (14). The reaction force drives the U-shaped slide plate (11) to slide vertically along the U-shaped vertical plate (1). Then, through the second L-shaped bracket (19), the U-shaped horizontal plate (2), the positioning horizontal plate (21), the fixed plate (31), and the monitoring camera (33) are raised and lowered for adjustment. Step 4: Start the servo motor (25) and control the motor shaft of the servo motor (25) to rotate slowly. The motor shaft of the servo motor (25) drives the limit swing arm (26) and the positioning pin to rotate synchronously. The positioning pin drives the limit slider (27) to slide up and down along the U-shaped channel steel (24), and synchronously drives the U-shaped channel steel (24) and the T-shaped slider (23) to slide left and right along a pair of positioning plates (22), thereby driving the positioning shaft and the notched gear (28) to slide left and right along the elliptical through hole. Step 5: When the notched gear (28) slides left and right, the meshing action of the notched gear (28) and the notched rack (29) first drives the notched gear (28) to rotate 90 degrees to the left and then slides along the notched rack (29) and abuts against the fixed pin (210) on the left. Then the notched gear (28) returns to its original position and drives the notched gear (28) to rotate 90 degrees to the right and then slides along the notched rack (29) and abuts against the fixed pin (210) on the right. The connecting plate (3), the fixed plate (31) and the monitoring camera (33) are moved back and forth in a circular motion to the left, down and right, and multi-directional monitoring is carried out through the monitoring camera (33).
