[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] It should be noted that all directional indications such as up, down, left, right, front, back, etc. in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0025] In addition, the terms "first," "second," and so on, used in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] The present invention will now be further described with reference to the accompanying drawings.

[0028] Example

[0029] like Figure 1 As shown, the pneumatic connecting rod lifting mechanism has a self-locking function and a strong limiting ability. After being lifted into place, it will not reset itself unless there is manual external force intervention. Its working principle is as follows:

[0030] When the lifting cylinder 2 extends upward, it pushes the connecting rod 1 6 to move upward. When the connecting rod 1 6 moves upward, it drives the connecting rod 2 7 and the connecting rod 3 8 to move to both sides. The movement of the connecting rod 2 7 and the connecting rod 3 8 to both sides drives the platform 3 to move upward in a straight line. When the lifting cylinder 2 extends to the maximum stroke, the connecting rod 2 7 and the connecting rod 3 8 form a vertical line. When the connecting rod 2 7 and the connecting rod 3 8 form a vertical line, the platform 3 rises to the top (such as Figure 2 ), when the connecting rod 2 7 and the connecting rod 3 8 are in a vertical line, they have a self-locking function, that is, when an external force acts on the platform 3, the platform 3 will not sink, realizing the self-locking function.

[0031] like Figure 2 As shown, the auxiliary parts of this lifting mechanism include a guide rod 9 and a linear bearing 12, which play a guiding role when the platform 3 moves upward. The compression spring 10 plays a role in eliminating gaps.

[0032] This lifting mechanism is used on aluminum cutting machines, such as Figure 3 As shown, when the clamping mechanism clamps the workpiece for cutting, the clamping force acts on the platform 3 of the jacking mechanism through the workpiece, but the jacking mechanism has a self-locking function and the platform 3 will not sink.

[0033] The utility model and its embodiments are described in this disclosure. This description is not restrictive. The drawings show only one embodiment of the utility model, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this disclosure and, without departing from the purpose of the utility model, designs a structure and embodiment similar to the technical solution without inventiveness, they shall fall within the scope of protection of the utility model.
