[0002] The mobile phone middle frame refers to the frame between the mobile phone screen and the mobile phone back cover for carrying various internal components, and is one of the important components in mobile phone production. In order to improve the aesthetics or durability of the mobile phone middle frame, methods such as embossing, spraying scales, mechanical buffing, and polishing are used to process the surface of the mobile phone middle frame. During the processing of the mobile phone middle frame, it is necessary to fix the mobile phone middle frame.

[0003] When the existing fixing device is in use, when fixing a relatively thin and light mobile phone middle frame, rigid fixing is generally adopted, which is easy to damage the mobile phone middle frame. When the mobile phone middle frame is processed, it will cause the mobile phone middle frame to vibrate, and it is easy to generate debris during the processing of the mobile phone middle frame, which is not easy to clean, and it is impossible to switch different perspectives to process the middle frame, resulting in inconvenient use and other problems.

A fan 18 is installed in the upper left corner of the front surface of the workbench 2. Two pipelines 19 are installed at the output end of the fan 18. The output ends of the pipelines 19 are installed with airbags 4.

[0026] In a specific embodiment of the present utility model, when the fan 18 works, the fan 18 transmits air flow to the airbag 4 through the pipeline 19, causing the airbag 4 to inflate and expand. The airbag 4 drives the flexible baffle 5 to flexibly fix the mobile phone middle frame, and the airbag 4 prevents the mobile phone middle frame from vibrating. When the handwheel 9 rotates, the handwheel 9 drives the threaded rod 7 to rotate. The threaded rod 7 drives the moving block 8 to move. The moving block 8 drives the adjusting rod 10 to adjust the angle, and thus the adjusting rod 10 can adjust different viewing angles of the workbench 2. The user can use it according to different angles.

[0027] Specifically, an air pump 11 is installed at the lower right corner of the front surface of the workbench 2. The output end of the air pump 11 is installed with a metal pipe 12, and the metal pipe 12 is fixedly installed with the base 13. A hose 16 is arranged on the top of the base 13, and the metal pipe 12, the base 13 and the hose 16 are communicated with each other.

[0028] In this embodiment: When the air pump 11 works, the air pump 11 conducts the air flow into the metal pipe 12, and the metal pipe 12 transmits the air flow to the hose 16 for spraying. The hose 16 can clean the debris generated during the processing of the mobile phone middle frame.

[0029] Specifically, the edge of the upper surface of the fixed base 1 is movably connected with the back surface of the workbench 2 through a hinge 14.

[0030] In this embodiment: Through the setting of the hinge 14, the workbench 2 can be adjusted in perspective.

[0031] Specifically, a limiting ring 17 is fixedly connected to the middle of the threaded rod 7.

[0032] In this embodiment: Through the setting of the limiting ring 17, when the moving block 8 contacts the limiting ring 17, the moving block 8 is limited during its movement on the threaded rod 7.

[0033] Specifically, the threaded rod 7 is provided with two sections of threads, and the spiral directions of the two sections of threads are opposite.

[0034] In this embodiment: Through the setting of the threaded rod 7, turning the handwheel 9 at the end of the threaded rod 7 can control the movement of the moving block 8.

[0035] Specifically, four anti-slip pads 15 are installed at the four corners of the lower surface of the fixed base 1.

[0036] In this embodiment: Through the setting of the anti-slip pads 15, the fixed base 1 is supported stably.

[0037] Specifically, two guide rods 20 are installed inside the clamping frame 3, and the guide rods 20 are slidably connected with the flexible baffle 5.

[0039] A fixing device for processing the surface of a mobile phone middle frame. The working principle and usage process of the present utility model are as follows:

[0040] When the fixing device is in use, usually the mobile phone middle frame is rigidly fixed, which is likely to damage the mobile phone middle frame; when the fan 18 works, the fan 18 transmits the air flow to the airbag 4 through the pipeline 19, so that the airbag 4 is inflated and expanded, and the airbag 4 drives the flexible baffle 5 to flexibly fix the mobile phone middle frame. After the flexible fixing, the fan 18 stops to avoid excessive extrusion of the mobile phone middle frame.

[0041] When processing the middle frame of the mobile phone, vibration will be caused to the middle frame of the mobile phone; through the setting of the airbag 4, the vibration of the middle frame of the mobile phone is prevented.

[0042] When the fixing device is in use, debris is easily generated during the processing of the middle frame of the mobile phone; when the air pump 11 works, the air pump 11 conducts the air flow into the metal tube 12, and then the metal tube 12 transmits the air flow to the hose 16 for spraying, and the hose 16 can clean the debris generated by the processing.

[0043] When the fixing device is in use, it may be necessary to switch different perspectives to process the middle frame; when the handwheel 9 rotates, the handwheel 9 drives the threaded rod 7 to rotate, the threaded rod 7 drives the moving block 8 to move, and the moving block 8 drives the adjusting rod 10 to adjust the angle, and then the adjusting rod 10 can adjust different perspectives of the workbench 2, which is convenient for use.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
