[0026] Please refer to Figure 1 In the embodiment, to realize avoidance, limiting mechanism is set in the rear of workbench 100.When workbench 100 needs to carry out plate material loading, workbench 100 moves towards the direction (rear) close to limiting mechanism;When plate material is completed cutting, workbench 100 needs to carry out plate material unloading, workbench 100 moves towards the direction (front) away from limiting mechanism. Please refer to Figure 2 And Figure 3When the workbench 100 moves towards the limiting mechanism (rear), the output end of the driving member 3 drives the follower seat 4 and the positioning member 5 arranged on the follower seat 4 to move downwards until the positioning member 5 is located in the positioning hook 1, and the positioning hook 1 and the positioning member 5 are matched to "hook" the workbench 100, thereby achieving accurate positioning of the workbench 100. When the limiting of the workbench 100 is to be released after the cutting is completed, the output end of the driving member 3 drives the follower seat 4 and the positioning member 5 arranged on the follower seat 4 to move upwards, so that the positioning hook 1 and the positioning member 5 gradually separate.

[0027] The above limiting mechanism can achieve positioning and releasing of the workbench 100 through the cooperation of the positioning hook 1 and the positioning member 5.

[0028] Please refer to Figure 2 In some embodiments, the opening of the positioning hook 1 faces upwards, and the spacing of the opening of the positioning hook 1 gradually increases from bottom to top. That is, in the present embodiment, the positioning member 5 is located above the positioning hook 1, and under the action of the driving member 3, the positioning member 5 gradually moves from top to bottom to the bottom of the positioning hook 1. Through the limitation of the spacing of the opening, a slope guide is provided for the movement of the positioning member 5, which facilitates smooth movement of the positioning member 5.

[0029] Please refer to Figure 2 In some embodiments, the positioning hook 1 includes a mounting portion 11 for fixedly connecting with the side wall of the workbench 100, a connecting portion 12 fixedly connected with the mounting portion 11, and an inclined plate 13 fixedly connected with the connecting portion 12, and the opening of the positioning hook 1 is formed by the connecting portion 12 and the inclined plate 13. In the present embodiment, the positioning hook 1 is composed of the mounting portion 11, the connecting portion 12 and the inclined plate 13, which are welded together, so that the positioning hook 1 is divided into three parts, and it is easy to form a special-shaped opening structure similar to "V" shape on the positioning hook 1.

[0030] Please refer to Figure 2 In some embodiments, the positioning member 5 is a first roller, the first roller can rotate relative to the follower seat 4, and the first roller is used for rolling contact with the inner wall of the inclined plate 13. When the workbench 100 gradually moves towards the direction of the limiting mechanism, the driving member 3 synchronously drives the follower seat 4 and the first roller to descend, and the first roller gradually contacts the inner wall of the inclined plate 13 and rolls downwards at the same time, and gradually rolls to the bottom of the positioning hook 1 under the guidance of the inclined surface of the inclined plate 13. Conversely, when the workbench 100 gradually moves away from the limiting mechanism, the first roller also contacts the inner wall of the inclined plate 13 and rolls upwards. The above arrangement can not only achieve follow-up limiting, but also reduce the friction force between the positioning member 5 and the inclined plate 13.
