A toggle gear 59 is rotatably connected in the inner wall of the installation cavity 58. The toggle gear 59 is used to control the top plate 513 to realize the separation of the two push plates 54. One end of the actuating gear 59 is engaged with a U-shaped trigger plate 510. A telescopic spring rod 511 is fixedly connected to the top of the trigger plate 510, and the top of the telescopic spring rod 511 is fixedly connected to the inner wall of the mounting cavity 58. The trigger plate 510 always maintains a downward resetting tendency through the telescopic spring rod 511.

The actuating tooth plate 512 is slidably connected to the inner wall of the mounting cavity 58, and a top plate 513 is fixedly connected to the top of the actuating tooth plate 512.

[0020] In this embodiment, as Figure 6 As shown, the top of the top plate 513 has a triangular structure, and the top plate 513 and the two push plates 54 are arranged vertically parallel to each other.

[0021] In this embodiment, as Figure 4 and Figure 7 As shown, the mounting component 52 includes an insertion rod 521 that is splinedly connected to the bottom end of the mounting plate 51. The bottom end of the insertion rod 521 is fixedly connected to the top end of the support plate 4. Several insertion interfaces 522 are arranged in a ring array on the outer wall of the insertion rod 521. The insertion interfaces 522 are used to restrict the sliding plate 525 and lock the mounting plate 51. A pressing plate 523 is slidably connected to the top of the mounting plate 51.

[0022] The computer software involved in the hardware carriers such as the welding machine body, laser welding head body, and drive motor in the technical solution is software technology known to those skilled in the art. It is merely applied to the aforementioned hardware carriers. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned hardware carriers, nor is it a key technical point of the utility model application.

[0023] Therefore, the "welding machine body", "laser welding head body", "drive motor" and other components involved in this application are physical functional modules that combine computer software programs or protocols in the prior art with the hardware carrier of this application. The computer software programs involved in these physical functional modules are all technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction relationship between the various physical functional modules, that is, the improvement of the overall structure of this application, in order to solve the corresponding technical problems to be solved by this application.

[0024] The laser welding machine operates as follows: First, manually align the mounting plate 51 with the insertion rod 521 and insert it. The edge of the insertion rod 521 contacts the edge of the slide plate 525. Squeeze the slide plate 525, and the slide plate 525 will retract into the mounting plate 51 until the mounting plate 51 is fully inserted. The slide plate 525 will move to the insertion interface 522. Move the lever 524 to quickly reset it through the torsion spring, and push the slide plate 525 into the insertion interface 522, thus completely locking the mounting plate 51 in the insertion rod 521. Simultaneously, the trigger plate 510 contacts the bearing plate 4, and the trigger plate 510 is squeezed upward, which in turn squeezes the telescopic spring rod 511 to retract. The trigger plate 510 drives the actuating gear 59 to rotate, and the rotation of the actuating gear 59 drives the actuating tooth plate 512 on the other side to move downward. The actuating tooth plate 512 drives the top plate 513 to move away from between the two push plates 54. At this time, since the top plate 57 is initially located between the two push plates 54, the operator manually puts in the workpiece and manually pushes the workpiece downward. The workpiece presses the top plate 57 into the movable cavity 56, and the two push plates 54 are no longer blocked. Through the closing movement of the spring telescopic rod 55, the two push plates 54 clamp the workpiece in the middle, completing the clamping operation of a single workpiece. The operator can follow the above steps to complete the installation of the remaining workpieces in sequence. Finally, when it is time to remove the workpiece, manually press the pressure plate 523. The pressure plate 523 pushes the top of the lever 524 downward. Through the lever principle, the bottom of the lever 524 moves the slide plate 525 out of the insertion interface 522. At this time, the installation plate 51 can be pulled out, and the operator can then manually remove the processed workpiece to complete the processing procedure.
