[0002] With the use of mobile phones, when the chip of the mobile phone fails and needs to be repaired, the mobile phone is often disassembled and the chip is taken out before the mobile phone chip can be repaired. In order to prevent the mobile phone circuit board chip from shifting during the repair process and affecting the repair work, a fixing tool is needed to fix the mobile phone circuit board chip. For example, patent number CN202122740348.2 is a fixing tool for circuit board chips when repairing mobile phones. The device has the following shortcomings:

[0003] The device controls the switch group to operate the second motor, which drives the diamond cam to rotate and changes the contact point between the diamond cam and the rectangular strip. At this time, the two rectangular strips lose the limit of the diamond cam and are affected by the tension spring to get close to each other, so that the four L-shaped clamps are closer to each other and the mobile phone circuit board chip is fixed and limited in both horizontal and vertical directions. As there are more and more mobile phone models nowadays, each mobile phone model is different, and the mobile phone circuit board chips are also different, such as square, L-shaped, rectangular, etc., and the device fixes the mobile phone circuit board from the four corners. Obviously, it cannot effectively fix the special-shaped mobile phone circuit board chips, and some mobile phone circuit board chips also have components on the back, so the fixing device needs to be adjusted in height.

[0040] Embodiment 2

[0041] Based on the embodiment one, the difference lies in that the clamped disc 44 on the upper part of the lifting rod 41 in the lifting mechanism 4 can be replaced with a clamp that is the same as the clamp 34, which is used to clamp some small chips, and when clamping small chips, only one clamp 34 needs to be pushed, and three fine-tuning knobs for adjusting the level of the device can be added to the lower part of the base 1, and a horizontal bubble is set on the upper surface of the turntable 2 to cooperate with the fine-tuning knob to adjust the level of the device.

[0042] Principle and process of this utility model:

[0043] Normally, the base 1 of the device is placed on a desktop, and then the staff determines whether the disc 44 needs to be raised by observing the chip on the mobile phone circuit board. If it needs to be raised, the push rod 42 only needs to be pushed forward. When the push rod 42 is pushed forward, the inclined rod 43 fixed on the surface of one side of the lifting rod 41 is lifted up, and the inclined rod 43 drives the lifting rod 41 to move upward and rise until it reaches the required height, and the limit block 45 on the upper part of the push rod 42 is against the limit groove on the lower part of the inclined rod 43 to achieve limit, so that the lifting rod 41 will not fall;

[0044] Then the staff can place the mobile phone circuit board chip on the upper part of the disc 44, and adjust the angle of the four cross bars 31 to clamp them in the clamping slot 7, and then turn the knob 36 on the side of the threaded rod 35 in the threaded groove 38 on the upper part of the cross bar 31 clockwise to make the threaded rod 35 rotate clockwise, driving the clamping plate 34 to move forward until the mobile phone circuit board chip is clamped.

[0045] During the maintenance process, if the staff needs to adjust the angle of the mobile phone circuit board chip, they only need to rotate the turntable 2 to adjust any angle. The turntable 2 meshes with the planetary gear 52 through the inner gear ring 53 fixed on the inner surface, and the planetary gear 52 meshes with the sun gear 51, thereby realizing 360° rotation. Then, the T-shaped ring groove 8 on the upper part of the base 1 and the T-shaped ring rod 9 on the lower part of the turntable 2 slide against each other and limit the position, so that the turntable 2 will not separate from the base 1 when rotating, and the U-shaped ring 65 shrinks inward and fits with the surface of the fixed rod 1 54 on the lower part of the sun gear 51 to realize the limit.

[0046] The U-shaped ring 65 rotates the knob 61 on one side of the threaded rod 62 clockwise, so that the threaded rod 62 rotates clockwise and the slider 64 moves backward. When the slider 64 moves backward, the fixed rod 68 fixed on its upper part will pull the first connecting rod 66 and the second connecting rod 67 to move backward together. Since the other ends of the first connecting rod 66 and the second connecting rod 67 are connected to the upper parts of the two sides of the U-shaped ring 65, a triangle is formed between the slider 64, the first connecting rod 66, and the second connecting rod 67. When one of the corners is pulled, the remaining two corners will shrink inward. Therefore, when the corner where the first connecting rod 66 and the second connecting rod 67 are connected to the slider 64 moves backward, the two sides of the U-shaped ring 65 can be shrunk inward, so that the inner wall of the U-shaped ring 65 fits with the outer surface of the fixed rod 1 54. Since the inner surface of the U-shaped ring 65 and the outer surface of the fixed rod 1 54 are both made of wear-resistant frosted material, properly tightening the U-shaped ring 65 can provide a certain resistance when the fixed rod 1 54 rotates.

[0047] When the maintenance is finished, the maintenance personnel rotates the knob 36 on one side of the threaded rod 35 counterclockwise, moves the clamping plate 34 backward to release the mobile phone circuit board chip, and then removes the mobile phone circuit board chip.
