Wherein, the press-fit structure comprises a fixed plate 310, a handle member 320, a movable rod 330 and a press-fit member 340, wherein the fixed plate 310 is provided with a fixed shaft 311, the handle member 320 is respectively and rotatably connected with the fixed shaft 311 and the movable rod 330, one end of the movable rod 330 is rotatably connected with the handle member 320, the other end of the movable rod 330 is rotatably connected with the press-fit member 340, and the press-fit member 340 is correspondingly arranged with the base 200.

The handle member 320 rotates around the fixed shaft 311 to drive the movable rod 330 to move, and the movable rod 330 drives the pressing member 340 to move, so that the pressing member 340 presses or releases the pressing of the adhesive member 400 on the base 200.

In this application embodiment, handle piece 320 can rotate around fixed axle 311, drives movable rod 330 and rotates, pressfitting piece 340 and movable rod 330 rotate and be connected for pressfitting piece 340 can not produce automatic bent axle motion under the condition of being straightened, thereby pressfitting piece 340 can stably carry out the pressfitting effect to bonding piece 400 on the base 200, makes bonding piece 400 have better bonding effect and reaches the structural requirement. And a certain interval can be provided between the pressing member 340 and the adhesive member 400, so that the next adhesive member 400 can be placed for pressure maintaining operation. The pressure maintaining jig has the advantages of simple structure, small volume, simplicity and convenience in operation and capability of improving the operation efficiency. The problems of large equipment volume and low operation efficiency are avoided, the operation speed and efficiency of the assembly line can be met, and a motor does not need to be operated, so that energy conservation and emission reduction are facilitated.

Thus, the support 100 can realize the connection and fixation of the pressing structure and the base 200, and meanwhile, the material consumption is reduced.

In this embodiment, for example, the fixing shaft 311 may extend away from the fixing plate 310 and form a preset included angle with the fixing plate 310, for example, 30 degrees, 45 degrees, etc., so that the handle member 320 rotates around the fixing shaft 311 to better drive the movable rod 330 and the pressing member 340 to rotate, thereby achieving a better pressing effect on the adhesive member 400.

For example, in the embodiment of the present application, as shown in fig. 1 and 2, the movable rod 330 may have a fold line structure or a linear structure, and the specific shape of the movable rod 330 may not be limited in the embodiment of the present application. In addition, the number of the movable rods 330 may be 2, or may be 1, or the like, and the specific number of the movable rods 330 may not be limited in the embodiment of the present application.

In this way, the rotational connection of the pressing member 340 to the movable rod 330 can be achieved by the pressing rod 341, while the pressing action on the adhesive member 400 is achieved by the pressing head 342. The specific shape and size of the pressure head 342 can be set according to the pressing requirement of the bonding member 400, so that the pressure head 342 and the bonding member 400 are aligned at the specific position to be bonded, and the pressing effect of the pressing member 340 on the bonding member 400 is improved.

In this embodiment, optionally, the pressure maintaining fixture further includes a connection plate 350 and a guide post 351; the connecting plate 350 is connected between the pressing rod 341 and the pressing head 342, the guide post 351 is penetrated through the connecting plate 350 and connected to the bracket 100, and the connecting plate 350 can slide relative to the guide post 351; and/or, the pressure maintaining jig further comprises a guide sleeve 352, the fixing plate 310 is provided with a connecting shaft 312, the connecting shaft 312 is connected to the guide sleeve 352, the guide sleeve 352 is sleeved on the pressing rod 341, and the pressing rod 341 can slide relative to the guide sleeve 352.

The connecting shaft 312 may extend away from the fixing plate 310 and may be disposed at a predetermined angle with respect to the fixing plate 310, for example, 30 degrees, 45 degrees, etc., so as to achieve a better fixing connection effect of the connecting shaft 312 to the guide sleeve 352.

In some alternative embodiments of the present application, the pressing head 342 is provided with a plurality of pressing ends 343, and the pressing ends 343 protrude toward the base 200 to press or release the bonding portion of the bonding member 400.

Thereby, the movement stroke of the pressing structure is adjusted, and the pressing force of the pressing structure to the adhesive 400 is controlled.

Specifically, when the limiting member 312 is connected to the higher limiting portion of the adjusting slot 360, the handle member 320 drives the movable rod 330 to rotate, so that the pressing member 340 has a longer stroke relative to the adhesive member 400 on the base 200, i.e. has a larger pressing force on the adhesive member 400. When the limiting member 312 is connected to the lower limiting portion of the adjusting slot 360, the handle member 320 drives the movable rod 330 to rotate, so that the pressing member 340 has a relatively short stroke with respect to the adhesive member 400 on the base 200, i.e. has a relatively small pressing force on the adhesive member 400. Thereby, the pressing force of the bonding member 400 is controlled by the pressing structure.
