Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Example 1, please refer to Figures 1-4 A touchscreen defoaming device includes a vertical support plate 2 fixed to one side of a support base 1, and a side connector 3 snapped onto the other side of the support base 1. A rotary knob 5 is provided in the middle of the side connector 3. Both ends of the rotary knob 5 are fixedly connected to a first screw 6. A first sliding plate 7 is sleeved on each of the two sets of first screws 6. A first limiting rod 10 is fixedly connected to the upper side of the first sliding plate 7. Two sets of limiting sliding openings 9 are provided through the side connector 3. A limiting rod 8 is fixedly connected to the inner wall of the limiting sliding opening 9. A second screw 11 is movably passed through the bottom of the vertical support plate 2. A second sliding plate 12 is sleeved on the second screw 11. A second limiting rod 13 is fixedly connected to the upper side of the second sliding plate 12. A rotating plate 14 is fixedly connected to the end of the second screw 11. A latch 15 is provided through the rotating plate 14.

[0025] The side connector 3 has a slot 4 through the middle, and the rotary knob 5 is located inside the slot 4. The external threads of the two sets of first screws 6 are symmetrically arranged, and the first screws 6 are threadedly connected to the first slide plate 7.

[0026] In this embodiment, the first screw 6 is threadedly connected to the first slide plate 7 so that the two sets of first slide plates 7 can move relative to each other.

[0027] The first sliding plate 7 is movably connected to the limiting rod 8, and the first sliding plate 7 is located inside the limiting slide 9.

[0028] In this embodiment, the first sliding plate 7 and the limiting rod 8 are connected by a limiting sliding opening 9 so that the two sets of first limiting rods 10 can move relative to each other.

[0029] The support seat 1 has a limiting groove 17, the second slide plate 12 is located inside the limiting groove 17, and the second slide plate 12 is threadedly connected to the second screw 11. The second limiting rod 13 is set perpendicularly to the first limiting rod 10.

[0030] In this embodiment, the second screw 11 is threadedly connected to the second slide plate 12 so that the second limiting rod 13 can be moved.

[0031] Several sets of slots 16 are equally spaced on one side of the vertical support plate 2, and the bolts 15 pass through the rotating plate 14 and fit into the slots 16.

[0032] In this embodiment, the position of the rotating plate 14 is fixed by the cooperation of the bolt 15 and the slot 16.

[0033] Specifically, by rotating the knob 5 inside the slot 4, the two sets of first screws 6 are rotated together. Under the cooperation of the symmetrical external threads and the limiting rods 8, the two sets of first sliding plates 7 are moved relative to each other along the limiting slide 9, which in turn moves the two sets of first limiting rods 10 relative to each other until the two sets of first limiting rods 10 are in contact with the two sides of the touch screen. Then, the rotating plate 14 drives the second screw 11 to rotate, which drives the second limiting rod 13 to move through the threaded connection between the second screw 11 and the second sliding plate 12 and the limiting slide 17, until the other two sides of the touch screen are in contact with the second limiting rod 13 and the side connector 3, respectively. The latch 15 passes through the rotating plate 14 and engages with the latch 16. This can prevent the touch screen from shifting position during the screen debubbling process, significantly improve the stability of the touch screen debubbling process, and can position touch screens of different sizes, making it highly applicable.

[0034] Example 2, please refer to Figures 1-4 A touch screen defoaming device is provided, wherein a forward and reverse motor 18 is fixedly installed on the upper end of a vertical support plate 2, a vertical lead screw shaft 19 is fixedly connected to the output end of the forward and reverse motor 18, a lifting block 20 is sleeved on the vertical lead screw shaft 19, a rotating connecting plate 22 is hinged to the lifting block 20 through a connecting hinge 21, a connecting frame plate 23 is fixedly connected to the lower end of the rotating connecting plate 22, a pressure roller 24 is provided on the inner side of the connecting frame plate 23, a fixing plate 27 is fixedly connected to the upper side of the side connecting body 3, a fixing rod 28 is fixedly connected to the fixing plate 27, and a spring 29 is sleeved on the fixing rod 28.

[0040] In this embodiment, the spring 29 on the fixing rod 28 works in conjunction with the slot 26 to press the touch screen tightly against the pressure roller 24.

[0041] Specifically, by starting the forward and reverse motor 18 at the upper end of the vertical support plate 2 in the forward direction, the vertical lead screw shaft 19 is driven to rotate. This causes the lifting block 20 to move downward along the vertical sliding opening 30 through the threaded connection between the vertical lead screw shaft 19 and the lifting block 20. Then, through the connecting hinge 21, the fixed rod 28 and the slot 26 drive the rotating connecting plate 22 to tilt continuously. The spring 29 keeps the pressure roller 24 in the connecting frame plate 23 pressing the touch screen tightly. Then, the forward and reverse motor 18 is started in the reverse direction, causing the pressure roller 24 to move closer to the vertical support plate 2. At this time, the pressure roller 24 can press the touch screen again, realizing the repeated screen pressing and debubbling function of the touch screen, with a good debubbling effect.
