[0032] Please refer to Figure 4 , Figure 5, as an embodiment of the present utility model, the clamping mechanism 17 includes a "T"-shaped mounting bracket 1701, wherein the lower end of the "T"-shaped mounting bracket 1701 is fixedly connected to the cross bar 15; a second telescopic cylinder 1702 is provided on the upper side of the "T"-shaped mounting bracket 1701, and the front end of the cylinder body of the second telescopic cylinder 1702 is fixedly connected to the side of the "T"-shaped mounting bracket 1701; a second movable shaft 1703 is provided inside the "T"-shaped mounting bracket 1701, and one end of the second movable shaft 1703 is fixedly connected to the top end of the piston rod of the second telescopic cylinder 1702; the other end of the second movable shaft 1703 penetrates through the side of the "T"-shaped mounting bracket 1701 and is connected to a movable locking block 1704, and a first limit card slot 1705 is opened inside the movable locking block 1704.

[0033] In the above-mentioned solution, the "T"-shaped mounting bracket 1701 is the main support component of the clamping mechanism 17. The lower end of the "T"-shaped mounting bracket 1701 is fixedly connected to the cross bar 15, ensuring the stability of the clamping mechanism 17 during the transfer process; the second telescopic cylinder 1702 is arranged on the upper side of the "T"-shaped mounting bracket 1701, and the front end of its cylinder body is fixedly connected to the side of the "T"-shaped mounting bracket 1701, providing a power source for the clamping mechanism 17; the second movable shaft 1703 is located inside the "T"-shaped mounting bracket 1701, one end of the second movable shaft 1703 is fixedly connected to the top end of the piston rod of the second telescopic cylinder 1702, and the other end of the second movable shaft 1703 penetrates through the side of the "T"-shaped mounting bracket 1701 and is connected to a movable locking block 1704; the first limit card slot 1705 opened inside the movable locking block 1704 can ensure that the car door is firmly fixed on the transfer equipment during the clamping process, preventing the car door from moving or falling off during the transfer process, realizing the firm clamping and stable support of the car door, and ensuring the safety and stability of the car door during the transfer process.

[0034] Furthermore, when it is necessary to clamp the car door, the piston rod of the second telescopic cylinder 1702 extends, pushing the second movable shaft 1703 to move towards the car door; the movement of the second movable shaft 1703 drives the movement of the movable locking block 1704, so that the first limit card slot 1705 inside the movable locking block 1704 aligns with and clamps the edge or specific part of the car door; when it is necessary to release the car door, the piston rod of the second telescopic cylinder 1702 retracts, pulling the second movable shaft 1703 to move away from the car door. The movement of the second movable shaft 1703 drives the movement of the movable locking block 1704, and then the first limit card slot 1705 releases the edge or specific part of the car door, thereby realizing the release of the car door.

[0035] Please refer to Figure 5 , as an embodiment of the present utility model, a limit rod 18 is fixedly connected to the front end of the "T"-shaped mounting bracket 1701, and a suction cup 19 is installed at the top end of the limit rod 18, and the suction cup 19 is used for sucking the car door.

[0036] In the above-described solution, the limit rod 18 is a rod with a certain length, and one end of it is fixedly connected to the front end of the "T"-shaped mounting bracket 1701. This design ensures the stability and accuracy of the limit rod 18 when the clamping mechanism 17 is working; the suction cup 19 is installed at the top of the limit rod 18 and is usually a material or device with adsorption ability, such as a rubber suction cup, an electromagnetic suction cup, etc. The suction cup 19 is used to contact the surface of the car door and generate a suction force; when the car door is placed at an appropriate position on the transfer device, the operator will activate the clamping mechanism 17 to make the "T"-shaped mounting bracket 1701 and the second telescopic cylinder 1702 work together to push the movable locking block 1704 to move towards the car door; during this process, the suction cup 19 at the top of the limit rod 18 will also approach the surface of the car door accordingly. Once the suction cup 19 contacts the surface of the car door, the suction cup 19 will generate a suction force to firmly adsorb the car door on the suction cup 19. This suction effect helps to further fix the car door and prevent it from moving or falling off during the transfer process due to bumps or sudden braking and other situations.

[0037] Please refer to Figure 3 , as an embodiment of the present invention, a fixed locking block 20 is provided at one end of the cross bar 15 close to the movable rod 606. The fixed locking block 20 is arranged opposite to the movable locking block 1704, and a second limit card slot 21 is opened inside the fixed locking block 20.

[0038] In the above-described solution, the fixed locking block 20 is provided at one end of the cross bar 15 close to the movable rod 606. The fixed locking block 20 is arranged opposite to the movable locking block 1704. This layout ensures that the door can receive uniform fixing forces from both sides during the transfer process, enhancing stability. A second limit card slot 21 is formed inside the fixed locking block 20, and the second limit card slot 21 is used to engage with the edge or specific part of the door to fix the door. When the door is placed at the appropriate position on the transfer device, the operator activates the clamping mechanism 17. At this time, the piston rod of the second telescopic cylinder 1702 extends, pushing the second movable shaft 1703 and the movable locking block 1704 towards the door. At the same time, since the fixed locking block 20 is already in the preset position, the edge or specific part of the door will be pushed into the second limit card slot 21 of the fixed locking block 20 to achieve the preliminary fixing of the door. As the movable locking block 1704 continues to move, the first limit card slot 1705 inside it will also engage with the edge or specific part on the other side of the door to further fix the door. When it is necessary to unload the door from the transfer device, the operator first releases the clamping mechanism 17. At this time, the piston rod of the second telescopic cylinder 1702 retracts, pulling the second movable shaft 1703 and the movable locking block 1704 towards the direction away from the door. The first limit card slot 1705 of the movable locking block 1704 will release the edge or specific part of the door. At the same time, the operator can manually or with the aid of tools pull the door out of the second limit card slot 21 of the fixed locking block 20. In this way, the door is completely released and can be safely unloaded from the transfer device. The fixed locking block 20 and the movable locking block 1704 cooperate with each other. Through the engagement and release of the second limit card slot 21 and the first limit card slot 1705 with the edges or specific parts on both sides of the door, firm fixing and stable support of the door during the transfer process are achieved.
