The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0020] This specific embodiment describes in detail the adjustable pressure maintaining device described in this application, such as Figure 1-Figure 3As shown, the adjustable pressure-maintaining device includes: a pressing component and a linear moving mechanism, the pressing component includes a fixed plate 1, a connecting plate 2, a sliding seat 3, a first connecting seat 4, an optical axis 5, a compression spring 6, a second connecting seat 7 and a pressure head module, the fixed plate 1 is connected to the moving end of the linear moving mechanism, the back of the connecting plate 2 is connected to the front of the fixed plate 1, the sliding seat 3 is slidably connected to the front of the connecting plate 2 in the vertical direction, the limiting opening is opened on the front and back sides of the sliding seat 3, the front of the connecting plate 2 is protruded with a limiting protrusion 16, the limiting protrusion 16 can extend into the limiting opening, the inner wall height of the limiting opening is greater than the height of the limiting protrusion 16, the limiting protrusion 16 can abut against the top wall of the limiting opening, the counterweight 17 The number is at least one, the counterweight 17 can be detachably stacked on the top of the sliding seat 3, the top of the first connecting seat 4 is connected to the bottom of the sliding seat 3, the top of the optical axis 5 is fixed to the bottom of the first connecting seat 4, and a through hole is opened on the second connecting seat 7. The bottom end of the optical axis 5 can extend from the through hole and be slidably connected to the through hole. A limiting block is set at the bottom end of the optical axis 5, and the two ends of the compression spring 6 respectively abut against the bottom surface of the first connecting seat 4 and the top surface of the second connecting seat 7. The top of the pressure head module is connected to the bottom surface of the second connecting seat 7. The pressing assembly can rise or fall in the vertical direction under the drive of the linear moving mechanism. The bottom end of the pressure head module is the extrusion end, and the extrusion end of the pressure head module can extrude the workpiece. When the workpiece is in use, the workpiece is first placed under the pressure head module. When the extrusion end of the pressure head module does not contact the workpiece, the sliding seat 3 falls with gravity until the limiting protrusion 16 abuts against the top wall of the limiting opening. The limiting protrusion 16 limits the sliding seat 3 to continue to move downward, preventing the sliding seat 3 from separating from the connecting plate 2. When the pressing starts, the pressing assembly gradually descends under the drive of the linear moving mechanism, and the extrusion end of the pressure head module contacts the workpiece. Since an optical axis 5 and a compression spring 6 are provided between the first connecting seat 4 and the second connecting seat 7, the optical axis 5 plays a guiding role, and the compression spring 6 plays a buffering role to prevent the workpiece from being subjected to excessive impact. After the extrusion end of the pressure head module contacts the workpiece, the pressing assembly continues to descend until the compression spring 6 is fully compressed and the top of the limiting protrusion 16 separates from the top wall of the limiting opening.
