[0024] In order to adapt to mobile phone middle frames of different widths, a support plate 21 is provided on the fixing component 2 in this embodiment, two slide grooves 22 are opened on the support plate 21, two threaded platforms 23 are provided on the support plate 21, and two slide grooves 22 are slidably connected with two fixing units 3; this arrangement enables that when fixing mobile phone middle frames of different widths, a relative displacement effect can be generated on the support plate 21 by controlling the two fixing units 3, so that it can play a fixing effect on mobile phone middle frames of different widths.

[0025] In order to fix the mobile phone middle frame of different lengths, the fixing unit 3 in this embodiment is provided with a fixing block 31, and a mounting groove 32 is provided on the opposite side of the two fixing blocks 31. A bidirectional screw rod 33 is rotatably connected in the mounting groove 32, and both ends of the two bidirectional screw rods 33 are threadedly connected with a fixing clamping block 39, and one end of the bidirectional screw rod 33 passes through the fixing block 31 and is fixedly connected with an adjusting knob 34.

This enables it to effectively fix mobile phone middle frames of different lengths.

[0026] Embodiment 2:

[0027] See also Figure 1-4 In order to achieve the effect of adjusting the position of the fixing assembly 2 during use, the two ends of the mounting frame 1 in this embodiment are rotatably connected to the connecting rods 11, the two ends of the connecting rods 11 are fixedly connected to the transmission wheels 12, and the transmission belts 13 are tensioned between the two transmission wheels 12.

[0028] In actual use, the staff can drive the output shaft of the driving motor 15 to drive the driving wheel 16 to rotate. During the rotation of the driving wheel 16, the driving belt 17 can be driven to rotate the driven wheel 14, so that the driven wheel 14 can drive the connecting rod 11 and the transmission wheel 12 to rotate, so that the transmission wheel 12 can drive the transmission belt 13 to rotate. A plurality of positioning columns 18 are provided on the top of the transmission belt 13, and the positioning columns 18 are used to limit the fixed component 2. Thus, the effect of driving the fixed component 2 to move when the transmission belt 13 rotates is achieved, and the effect of facilitating multi-point processing of the mobile phone middle frame during the processing is achieved.

[0029] The working principle of the above embodiment is:

[0030] 1. In the process of processing the mobile phone middle frame, the staff can first place the mobile phone middle frame between the four fixed clamping blocks 39, and then control the rotating handle 38 to drive the threaded rod 37 to rotate, and the threaded rod 37 can produce a displacement effect during the rotation of the threaded rod 37, and the fixed block 31 can be displaced during the displacement of the threaded rod 37, so that the fixed clamping block 39 provided on the fixed block 31 can fit with the mobile phone middle frame, and can play a positioning effect on the mobile phone middle frame in the horizontal direction, and then the staff can control the adjusting knob 34 to drive the bidirectional screw rod 33 to rotate, and the two fixed clamping blocks 39 provided on the bidirectional screw rod 33 can be driven to produce an inward displacement effect during the rotation of the bidirectional screw rod 33, so that the mobile phone middle frame can be positioned longitudinally, and the fixing effect of the mobile phone middle frame is completed at this time.

[0031] 2. When the position of the fixed component 2 needs to be adjusted, the staff can drive the output shaft of the driving motor 15 to drive the driving wheel 16 to rotate. During the rotation of the driving wheel 16, the driving belt 17 can be driven to rotate the driven wheel 14, so that the driven wheel 14 can drive the connecting rod 11 and the transmission wheel 12 to rotate, so that the transmission wheel 12 can drive the transmission belt 13 to rotate. By setting a plurality of positioning columns 18 on the top of the transmission belt 13, the positioning columns 18 are used to limit the fixed component 2. Thereby, the effect of driving the fixed component 2 to be displaced when the transmission belt 13 rotates is achieved, and the effect of facilitating multi-point processing of the mobile phone middle frame during the processing is achieved. When the fixed component 2 needs to be adjusted up and down, the staff can control the pneumatic push rod 191 to drive the connecting platform 192 to produce the effect of up and down displacement, thereby driving the support plate 21 to produce up and down displacement.
