Detailed Implementation

[0023] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0024] Example: A rotatable fixing bracket for repairing mobile phone LCD screens, such as... Figures 1-3 As shown, the assembly includes a base plate 1, a first motor 2, a connecting plate 3, a rotating plate 4, a placement plate 5, a fixing plate 6, a connecting rod 7, a second motor 8, a gear 9, a guide block 10, a moving plate 11, a rack 12, and a clamping plate 121. The base plate 1 serves as the mounting carrier for the parts. A movable groove is formed on the upper side of the base plate 1. The first motor 2 is mounted on the upper side of the base plate 1 via bolts. The upper end of the output shaft of the first motor 2 is connected to the connecting plate 3. A rotating plate 4 is rotatably connected to the connecting plate 3. A placement plate 5 is rotatably connected to the rotating plate 4. A fixing plate 6 is welded to the rear side of the placement plate 5. A connecting rod 7 is connected to the fixing plate 6. The rear side of the placement plate 5 is symmetrically connected to the mounting plates via bolts. The first motor 2 is equipped with a second motor 8. The output shaft of the first motor 2 is connected to a gear 9. Guide blocks 10 are symmetrically welded on the upper and lower sides of the rear side of the placement plate 5. Moving plates 11 are slidably connected to the four guide blocks 10. Racks 12 are connected to the four moving plates 11. Two adjacent racks 12 are connected to clamping plates 121 facing away from each other. The four clamping plates 121 are located on the left and right sides of the placement plate 5 respectively. The second motor 8 is started to drive the moving plates 11, racks 12 and clamping plates 121 at the same level to move away from each other, so that the four clamping plates 121 unfold to place the mobile phone. The second motor 8 is controlled to rotate in the opposite direction to drive the clamping plates 121 to perform a reset action, and the clamping plates 121 clamp the two sides of the mobile phone.

[0025] like Figure 4As shown, it also includes an air pump 13, a delivery pipe 14, a mounting plate 15, and a suction cup 16. The air pump 13 is mounted on the base plate 1 and is located behind the first motor 2. The mounting plates 15 are symmetrically welded to the upper side of the base plate 1. The motor is located between the two mounting plates 15. The suction cup 16 is connected to the lower side of the two mounting plates 15. The delivery pipe 14 is symmetrically connected to the air pump 13. The other end of each of the two delivery pipes 14 passes through the adjacent mounting plates 15 and communicates with the suction cup 16.

[0026] like Figure 5 As shown, it also includes a drawer box 17, drawer compartments 18, elastic elements 20, and locking beads 21. The drawer box 17 is placed on the upper side of the base plate 1. The drawer box 17 is located in front of the first motor 2, and a slot is opened at the center of the lower side. The drawer compartments 18 are symmetrically slidably connected to the drawer box 17. The right side of each drawer compartment 18 is connected to a handle to facilitate opening the drawer compartment 18. The elastic element 20 is connected in the movable groove on the base plate 1. The top of the elastic element 20 is connected to the locking bead 21, which engages with the slot on the drawer box 17.

[0027] like Figure 6 As shown, it also includes a support frame 24 and a light 25. The support frame 24 is connected to the side of the placement plate 5, and the light 25 is installed on the support frame 24.

[0028] like Figure 5 As shown, it also includes an anti-slip mat 22, which is connected to the lower side of the base plate 1.

[0029] like Figure 1 As shown, it also includes a protective pad 23, with the protective pad 23 connected to one side of the two horizontally aligned clamps 121 facing each other.

[0030] like Figure 5 As shown, it also includes a magnet 19, and the lower side of the drawer compartment 18 is connected to the magnet 19.

[0031] When using this device, first, place the base plate 1 on the table, with the protective pad in contact with the table and the suction cup 16 in contact with the table. Press down on the suction cup 16 to expel some of the air between the suction cup 16 and the table. Start the air pump 13, which extracts the remaining air between the suction cup 16 and the table through the delivery pipe 14, fixing the suction cup 16 to the table. The suction cup 16 and the anti-slip pad 22 cooperate to fix the base plate 1. Start the second motor 8, whose output shaft rotates, driving the gear 9 to rotate. Through the meshing of the gear 9 and the rack 12, the moving plate 11 is moved, causing the four-clamp plate 121 to unfold. Place the mobile phone on the placement plate 5. The output shaft of the second motor 8 is controlled to rotate in reverse, driving the gear 9 to rotate in reverse. Through the meshing of the gear 9 and the rack 12, the moving plate 11 is driven to reset. The clamping plate 121 clamps the two sides of the mobile phone. The above operation can adjust the width of the clamping plate 121 for mobile phones of different sizes, so that subsequent repair work can be carried out stably. The protective pad 23 can protect the mobile phone and reduce the friction of the clamping plate 121 on the surface of the mobile phone. The drawer box 17 is placed on the table. The locking ball 21 moves downward under the pressure of the drawer box 17. The elastic element 20 deforms adaptively. The drawer box 17 is moved until the slot on the drawer box 17 is above the locking ball 21. The elastic element 20 returns to its original shape, and the locking ball 21... Under the elastic force of the elastic element 20, it resets and engages with the slot on the drawer box 17, thereby limiting the drawer box 17. The drawer compartment 18 moves forward and opens, allowing the tools inside the drawer compartment 18 to be removed and detached from the magnet 19. The tools are then used to repair the mobile phone. During the repair process, the first motor 2 is started. The output shaft of the first motor 2 rotates, driving the connecting plate 3, rotating plate 4, placement plate 5, fixing plate 6, connecting rod 7, second motor 8, gear 9, guide block 10, moving plate 11, rack 12, clamping plate 121, air pump 13, delivery pipe 14, mounting plate 15, suction cup 16, and anti-slip pad 22 to rotate. Once the mobile phone has rotated to a suitable angle, the motor is turned off. Rotate the rotating plate 4 to adjust the height of the corresponding components, turn on the light 25 to illuminate the mobile phone repair area. The above operations facilitate the repair of the mobile phone by the staff. After the repair work is completed, put the tools back into the drawer compartment 18 and attach them to the magnet 19 to limit their movement and prevent the tools from shifting in the drawer compartment 18. Move the drawer compartment 18 back to reset it, remove the drawer box 17 from the base plate 1, operate the motor as described above to open the four-clamp plate 121, remove the repaired mobile phone, turn off the motor, control the air pump 13 to run in reverse and inject air into the suction cup 16 through the delivery pipe 14, and remove the base plate 1 from the table.
