The power module of the embodiment is an oil cylinder 2 fixed on a beam at the upper part of the frame 1. The oil cylinder 2 adopts a front-rear double-oil-cylinder layout and directly drives the longitudinal lifting action of the first upper pressing assembly 61 a.

The frame 1 is provided with a longitudinal guide structure 8, and the first upper pressing component 61a, the first lower supporting component 61b and the second upper pressing component 62a are all connected with the longitudinal guide structure. The guide structures of the embodiment are respectively provided with 2 guide structures on the left side and the right side of the frame and are symmetrically arranged.

The adjacent two of the first upper pressing component 61a, the first lower supporting component 61b and the second upper pressing component 62a are also connected by a unidirectional linkage pair 7. The one-way linkage pair of the embodiment is provided with 3 one pairs respectively at the left side and the right side of the frame and is symmetrically arranged.

As shown in fig. 2, the one-way link pair 7 includes a link 71 and a link pin 72. The number of the unidirectional linkage pairs 7 in the figure is 2, taking the upper part as an example: the upper end of the linkage piece 71 is a fixed end and is fixed with the side wall of the first upper pressing component 61a, the main body extends vertically downwards, and the middle lower part of the main body part is provided with a linkage pin matching hole 711 in a penetrating manner. Correspondingly, a linkage pin 72 is fixed on the side wall of the lower first lower support component 61b, and the main body of the linkage pin 72 extends along the horizontal direction and is inserted into the linkage pin matching hole 711 in a matching manner. The linkage pin matching hole 711 has a large upper end aperture and a small lower end aperture. Fig. 2 shows the first upper pressing assembly 61a and the first lower supporting assembly 61b in a separated state, in which the interlocking pin 72 is located at the lowermost end of the interlocking pin fitting hole 711. Another unidirectional linkage pair 7 is used between the lower first lower supporting component 61b and the second upper pressing component 62a, and the structure is similar to that of the upper one. The only difference is that: the linkage piece 71 on the first lower supporting component 61b is directly connected with the linkage pin 72 in an integrated manner, and the second upper pressing component 62a is only provided with the linkage pin 72 and is not provided with the linkage piece 71.
