These synchronization devices are common and mature in the field of electric control, and therefore will not be described in detail in specific embodiments.

[0031] Please see Figures 1 to 3 In this embodiment, the mounting plate 2 is provided with a driving component for moving the mounting block 3. The driving component includes two sliding blocks 8, which are fixedly connected to the top surfaces of the two mounting blocks 3 respectively. A sliding groove 6 is provided on one side of the mounting plate 2 near the mounting block 3. Both sliding blocks 8 extend into the interior of the sliding groove 6. A dual-axis motor 10 is fixedly installed inside the sliding groove 6.

A second motor 5 is fixedly installed on the opposite side of the two limiting plates 4. A clearance groove 15 is opened on the side of the two mounting blocks 3 near the limiting plates 4. A support plate 16 with one end penetrating through the clearance groove 15 and extending into the placement groove 9 is placed on the bottom surface of the two limiting plates 4. A second screw 14 with one end penetrating through the support plate 16 and extending into the mounting block 3 is fixedly connected to the output shaft of the two second motors 5.

[0037] Specifically, the second motor 5 is started, and the output shaft of the second motor 5 drives the second screw 14 to rotate. Through the threaded connection between the second screw 14 and the support plate 16 and the sliding connection between the support plate 16 and the relief groove 15, the second screw 14 drives the support plate 16 to move. The support plate 16 and the clamping plate 11 fit together to support the clamping plate 11 and improve the stability of the clamping plate 11.

[0038] It should be noted that this application can ensure that the output shafts of the two second motors 5 rotate simultaneously by employing a synchronization controller or other synchronization device, thereby achieving synchronous operation. These synchronization devices are common and mature in the field of electric control, and therefore will not be described in detail in specific embodiments.

[0039] The working principle of the above embodiments is as follows:
