Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0022] Reference Figure 1-Figure 3 A rotatable mobile phone screen repair device includes a base 1 and a fixing plate 2. A plurality of fixing columns are arranged between the base 1 and the fixing plate 2. The base 1 is rotatably connected to a rotating seat. The fixing plate 2 can be moved to make the base 1 rotate on the rotating seat.

[0023] A fixing mechanism is provided on the fixing plate 2, and the fixing mechanism includes a nut seat 3, a push plate 4, a push rod 5, a clamping plate 6, a hollow rod 7, a suction cup 8, a circular plate 9, and a cylinder 10. Slide grooves are respectively provided at both ends of the fixing plate 2, the nut seat 3 is slidably connected in the slide groove, the push plate 4 is fixedly connected to the upper end of the nut seat 3, the push plate 4 is slidably connected to the upper surface of the fixing plate 2, and slide holes are respectively provided on both ends of the push plate 4, and a plurality of push rods 5 are slidably connected in the slide holes, and the clamping plate 6 is fixedly connected to the end of the push rod 5 away from the push plate 4. A clamping spring 16 is fixedly connected between the push plate 4 and the clamping plate 6. A clamping head is provided on the side wall of the clamping plate 6. The contact area between the clamping head and the middle frame of the mobile phone is small, so it will not hinder the hot air gun from blowing between the back cover and the middle frame. A through hole is opened on the side wall of the fixed plate 2. The hollow rod 7 is slidably connected in the through hole. The suction cup 8 is fixedly connected to one end of the hollow rod 7. The circular plate 9 is fixedly connected to the other end of the hollow rod 7. The cylinder 10 is slidably connected to the outer side wall of the circular plate 9. The side wall of the bottom of the circular plate 9 is opened with a through hole. The air port, the hollow rod 7 is sealed and slidably connected with the cylinder 10, the hollow rod 7 passes through the upper end surface of the cylinder 10, a desorption port is provided on the side wall of the cylinder 10, a sealing plate 15 is fixedly connected to the side wall of the circular plate 9, the sealing plate 15 is slidably connected with the side wall of the cylinder 10, a torsion spring 18 is fixedly connected between the inner side wall of the cylinder 10 and the hollow rod 7, when the circular plate 9 slides normally, the sealing plate 15 blocks the desorption port, and the air in the cylinder 10 enters the hollow rod 7 from the air outlet of the circular plate 9, and then slips out from the suction cup 8 When the disassembly is completed and the back cover needs to be removed, it is only necessary to rotate the back cover to drive the suction cup 8 and the hollow rod 7 to rotate, and drive the circular plate 9 and the sealing plate 15 to rotate. The sealing plate 15 will no longer seal the desorption port, and the outside air will enter the cylinder 10 from the desorption port. The air pressure in the cylinder 10 is restored and the suction cup 8 will no longer have an adsorption force on the back cover, so the back cover can be easily removed, and then the torsion spring 18 drives the hollow rod 7 and the sealing plate 15 to reset and reseal them. A reset spring 17 is fixedly connected between the cylinder 10 and the fixed plate 2.

[0024] The fixed structure also includes a fixed block 11, a screw rod 12, a gear 13, and a rack plate 14. The fixed block 11 is fixedly connected to both sides of the lower end surface of the fixed plate 2, and the two screw rods 12 are rotatably connected to the fixed block 11 respectively. The thread directions of the two screw rods 12 are opposite. The gear 13 is fixedly connected between the two screw rods 12, and the rack plate 14 is fixedly connected to the outer wall of the cylinder 10. The rack plate 14 is meshed with the gear 13. When the rack plate 14 moves downward, it drives the gear 13 to rotate, thereby the two screw rods 12 rotate, and the two nut seats 3 approach each other, and vice versa.

[0025] The lower end surface of the cylinder 10 is fixedly connected with a spring rod, the lower end surface of the spring rod is rotatably connected with a hook 19, the upper end surface of the base 1 is fixedly connected with a placement block 20, and the side wall of the placement block 20 is fixedly connected with a U-shaped ring 21 at equal intervals.

[0026] In the utility model, when in use, first put the back cover of the mobile phone downward on the suction cup 8, and under the action of the mobile phone's own weight, drive the suction cup 8 and the hollow rod 7 to move downward, drive the circular plate 9 to move downward, squeeze out the air in the cylinder 10, and the air in the cylinder 10 slips out from the gap between the suction cup 8 and the back cover of the mobile phone along the hollow rod 7. The cylinder 10 is under negative pressure, and the suction cup 8 tightly adsorbs the back cover. If you feel that the adsorption is not tight enough, you can also hold the cylinder 10 by hand and press the mobile phone down a distance, pull the hook 19 to drive the cylinder 10 to move downward, thereby driving the rack plate 14 to move downward, the rack plate 14 drives the gear 13 to rotate, thereby driving the screw rod 12 to rotate, driving the two nut seats 3 to move closer to each other, driving the two push plates 4 to move closer to each other, and driving the clamp on the clamping plate 6 to clamp the middle frame of the mobile phone. The contact surface between the clamping head and the middle frame is small, so it will not hinder the hot air gun from moving to Blow between the back cover and the middle frame, but the clamping force is weak at this time, the mobile phone will still move downward, as the cylinder 10 continues to move downward, the clamping spring 16 is continuously compressed, the clamping force is also greater, and the mobile phone will no longer move downward, and the hook 19 is hung on the nearest U-shaped ring 21. At this time, the spring rod is stretched, giving the cylinder 10 and the suction cup 8 a downward force, turning the base 1 and starting the hot air gun to blow towards the gap between the middle frame and the back cover. As the colloid is continuously blown, it softens, and the back cover is separated from the middle frame under the action of tension. The middle frame is clamped while the back cover is still adsorbed by the suction cup 8. After separation, no large displacement will occur, and no damage will be caused to the components inside the mobile phone. The operator does not need to manually contact the middle frame and the back cover. At the same time, the operator will not blow the hot air gun for too long due to inaccurate estimation, causing the paint on the back cover to melt, thereby destroying the aesthetics of the mobile phone.

[0027] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
