[0031] like Figure 7 As shown, the locking mechanism 24 includes a toggle block 2401, a fixed rod 2402, a linkage rod 2403, a transmission assembly 2404 and a latch 2405. The toggle block 2401 is rotatably mounted on the fixed plate 1. A torsion spring is installed on the toggle block 2401. The other end of the torsion spring is fixedly connected to the fixed plate 1. The upper and lower ends of the toggle block 2401 are fixedly mounted with the fixed rod 2402. The transmission assembly 2404 is fixedly mounted at the upper and lower positions of the fixed plate 1.

[0032] like Figure 8 As shown, the transmission assembly 2404 includes a sliding cylinder 2406, a first piston 2407 and a second piston 2408, the first piston 2407 and the second piston 2408 are respectively sealed and slidably installed in the sliding cylinder 2406, the sliding cylinder 2406 is fixedly connected to the fixed plate 1, one end of the latch 2405 is fixedly connected to the second piston 2408, the end of the second piston 2408 is fixedly connected to a connecting block 2409, a support rod 2410 is hinged on the side wall of the connecting block 2409, the end of the support rod 2410 is overlapped on the inner wall surface of the sliding cylinder 2406, a spring piece 2411 is fixedly installed on the side wall of the connecting block 2409, the other end of the spring piece 2411 is pressed against the support rod 2410, and the latch 2405 passes through the sliding cylinder 2406. A baffle ring 2413 is fixedly installed at the position of the cylinder 2406, and a spring 2412 is installed between the baffle ring 2413 and the end of the sliding cylinder 2406. A limiting flow hole 2414 is provided on the second piston 2408; an air hole 2415 is provided on the first piston 2407, and a rubber plate 2416 is fitted on the end of the second piston 2408 away from the second piston 2408, and the rubber plate 2416 fits on the air hole 2415. A piston rod 2417 is fixedly connected to the first piston 2407, and the piston rod 2417 is hinged to the linkage rod 2403. By setting the transmission assembly 2404 and adjusting the gear 6 and the toggle block 2401 to be in any state, it can be ensured that the pin 2405 is pulled out normally, thereby allowing the sliding support frame 5 to be reset normally.

[0033] like Figure 9 As shown, a sliding groove 12 is provided on the surface of the fixed plate 1, and a slider 13 is slidably connected in the sliding groove 12. One side of the slider 13 is fixedly connected to the sliding support frame 5, and one end of the tension spring 14 is fixedly connected to the other side of the slider 13, and the other end of the tension spring 14 is fixedly connected to the surface of the fixed plate 1.

[0034] Working process: When adjusting, the driving gear 10 is connected to the external motor. When multiple photovoltaic panels need to be adjusted synchronously at one time, the adjacent driving gears 10 are connected through the transmission shaft to achieve synchronous drive;

[0035] like Figure 5 As shown, when the driving gear 10 rotates counterclockwise, the first latch 82 and the second latch 92 are synchronously moved. Since the left side of the first latch 82 is blocked by the first limit block 83, and the second latch 92 is tilted due to no obstruction, the driving gear 10 drives the first latch 82 to move the upper pull plate 8 to the left; when the driving gear 10 rotates clockwise, similarly, the first latch 82 is tilted, and the second latch 92 is blocked by the second limit block 93, and the driving gear 10 drives the second latch 92 to move the lower pull plate 9 to the left;

[0036] like Figure 3 、 Figure 4 As shown, the upper pull plate 8 or the lower pull plate 9 pulls the sliding support frame 5 to move synchronously, so that the block 22 is disengaged from the slot 3, so that the adjusting gear 6 is engaged with the teeth 4, and the transmission gear 11 is engaged with the driving gear 10 to realize power transmission, and the transmission gear 11 plays a role in deceleration and increasing torque to adjust the position of the adjusting rod 2, and through the cooperation of the first hinge rod 16 and the second hinge rod 17, the adjusting plate 19 is pulled or pushed by the pull rod 18, and finally the angle of the mounting plate 21 is adjusted;

[0037] like Figure 6 As shown, when the upper pull plate 8 or the lower pull plate 9 moves, the corresponding sliding pin 25 is synchronously driven to move in the guide groove 23. When it moves to the position of the rising section 232, the sliding pin 25 is attracted to move upward under the action of the magnetic block 236, and synchronously drives the upper pull plate 8 or the lower pull plate 9 to rotate to both sides, thereby breaking away from the connection with the driving gear 10. Under the tension of the tension spring 14, the sliding pin 25 slides along the inclined surface of the rising section 232 to the connection with the descending reset section 233;

[0038] like Figure 7 As shown, once the driving gear 10 starts to rotate, its teeth will continuously push the toggle block 2401 to rotate upward or downward. Regardless of whether the toggle block 2401 rotates upward or downward, it will drive the fixed rods 2402 on the upper and lower sides to rotate, thereby utilizing the linkage rod 2403 to pull the piston rod 2417 and the first piston 2407, so that the pressure between the first piston 2407 and the second piston 2408 is reduced, the second piston 2408 moves downward, and synchronously drives the latch 2405 to move downward, so that its end is inserted into the slot 234, blocking the sliding pin 25 from resetting. When the second piston 2408 moves downward, the support rod 2410 will not be opened, and the second piston 2408 will not be opened. 2408 will not encounter any resistance; when the toggle block 2401 passes through a tooth of the driving gear 10 and enters its tooth groove, the toggle block 2401 resets, causing the first piston 2407 to reset. During the reset, the rubber plate 2416 opens under the push of the air flow, preventing excessive increase in air pressure. Under the action of the spring 2412, the second piston 2408 moves upward, and the support rod 2410 is pushed outward by the friction force, thereby increasing the friction force of the second piston 2408 moving upward and slowing its movement speed. As the driving gear 10 continues to rotate, the first piston 2407 continuously provides negative pressure, ensuring that the latch 2405 will not fall out of the slot 234;

[0039] When the driving gear 10 stops rotating, the first piston 2407 cannot provide negative pressure, and the second piston 2408 is reset under the action of the spring 2412. The latch 2405 disengages from the slot 234, and the sliding pin 25 loses its obstruction. Under the action of the tension spring 14, the sliding support frame 5 is driven to reset, so that the card block 22 is locked into the card slot 3, the adjustment gear 6 is separated from the teeth 4, and the driving gear 10 is separated from the transmission gear 11, completing the adjustment.

[0040] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the claims of this patent application.
