A fixing device 5 is arranged inside the workbench 2. A cavity 51 is opened inside the workbench 2. An adsorption groove 52 is opened at the top end inside the cavity 51. A threaded rod 53 penetrates and is rotatably connected inside the cavity 51. The outer wall of the threaded rod 53 penetrates and is threadedly connected with a piston plate 55. A moving groove 56 is opened on the inner wall of the placement groove 3. A first spring 57 is fixedly connected to the inner wall of the moving groove 56. One end of the first spring 57 far from the inner wall of the moving groove 56 is fixedly connected to a limiting plate 58.

[0024] Among them, one end of the limiting plate 58 far from the first spring 57 is an inclined surface, and one end of the limiting plate 58 close to the first spring 57 is fixedly connected to a pull rod 59.

[0025] By pulling the pull rod 59, pulling the pull rod 59 can drive the limiting plate 58 to move inside the moving groove 56 and compress the first spring 57 by the limiting plate 58.

[0026] Among them, the pull rod 59 penetrates and is slidably connected to the inner wall of the moving groove 56, and a ventilation port 54 is opened at one end of the cavity 51 away from the piston plate 55.

[0027] Through the ventilation port 54, during the movement of the piston plate 55, the air inside the cavity 51 can be discharged from the cavity 51, so that a negative pressure space is generated inside the cavity 51.

[0028] Among them, an adjusting device 6 is provided at the top of the jig base 1, and a fixing column 61 is fixedly connected to the top of the jig base 1.

[0029] Through the adjusting device 6, the adjusting device 6 can adjust the angle of the workbench 2, which is convenient for the staff to assemble the mobile phone.

[0030] Among them, a rotating shaft 62 is rotatably connected to the inner wall of the fixing column 61, and the top of the rotating shaft 62 is fixedly connected to the bottom end of the workbench 2.

[0031] Through the rotating shaft 62, the rotating shaft 62 rotates inside the fixing column 61, and then can drive the workbench 2 to rotate to adjust the angle of the mobile phone to be assembled.

[0032] Among them, a limiting groove 63 is opened at the top of the jig base 1, a connecting block 64 is fixedly connected to the bottom end of the workbench 2, and a second spring 65 is fixedly connected to the inner top end of the connecting block 64.

[0033] Through the second spring 65, the second spring 65 can support the limiting insertion rod 66, and the connecting block 64 can limit the movement track of the limiting insertion rod 66.

[0034] Among them, a limiting insertion rod 66 is fixedly connected to the bottom end of the second spring 65, and the cross-sectional dimension of the limiting insertion rod 66 is the same as that of the limiting groove 63.

[0035] Through the limiting insertion rod 66, when the limiting insertion rod 66 is inserted into the limiting groove 63, the workbench 2 can be limited.

[0036] The present utility model provides a fixed jig for mobile phone assembly, and the specific working principle is as follows:

[0037] The staff places the mobile phone to be assembled inside the placement slot 3. The mobile phone squeezes the inclined surface of the limit plate 58. The limit plate 58 moves into the movement slot 56 under the extrusion and squeezes the first spring 57. At this time, the limit plate 58 continues to move into the movement slot 56 until it is completely inside the movement slot 56. The mobile phone is completely placed inside the placement slot 3, and the bottom end is in contact with the outer wall of the placement slot 3. At this time, the first spring 57 is released from the external pressure, and the first spring 57 drives the limit plate 58 to reset through its own elastic force. The limit plate 58 limits the mobile phone. Rotate the threaded rod 53. The rotation of the threaded rod 53 drives the piston plate 55 to move. The piston plate 55 moves inside the cavity 51. The piston plate 55 discharges the air inside the cavity 51 through the air exchange port 54. At this time, a negative pressure state is formed between the cavity 51 and the adsorption slot 52, and the mobile phone is fixed inside the placement slot 3. At this time, the mobile phone is assembled. If the angle of the workbench 2 needs to be adjusted, move the limit insertion rod 66 upward. The limit insertion rod 66 moves inside the connection block 64 and squeezes the second spring 65. The second spring 65 is squeezed and drives the limit insertion rod 66 to contract inside the connection block 64. The limit insertion rod 66 disengages from the inside of the limit slot 63, and the workbench 2 is released from the limit. At this time, rotate the workbench 2. The rotation of the workbench 2 drives the rotating shaft 62 to rotate inside the fixed column 61. When it rotates to the appropriate angle, release the squeezing force on the limit insertion rod 66. At this time, the second spring 65 drives the limit insertion rod 66 to insert into the limit slot 63, and the limit on the workbench 2 is restored again.
