[0008] Its working principle is as follows: clamping arm one and clamping arm two are arranged opposite to each other so that there is a sufficient gap between the two to clamp the buttons, and the power source is used to drive clamping arm one and clamping arm two to move toward or away from each other, and clamping arm one and clamping arm two can achieve translational movement toward or away from each other, and the translational movement stabilizes the movement, thereby increasing the accuracy of clamping arm one and clamping arm two in clamping buttons, and the two move away from each other to open clamping arm one and clamping arm two, and the two move toward each other to clamp clamping arm one and clamping arm two, which can better control clamping arm one and clamping arm two to clamp buttons smoothly, thereby improving the accuracy of the button clamping device.

[0009] In the above-mentioned clamping device, a pushing rod capable of driving the clamping arm 1 to move horizontally is provided between the clamping arm 1 and the power source, one end of the pushing rod is connected to the clamping arm 1, and a connecting arm assembly capable of driving the clamping arm 2 to move backward horizontally when the pushing rod moves forward is provided between the clamping arm 2 and the pressure plate.

The connecting arm assembly plays a transmission role, so that when the pushing rod drives the clamping arm 1 to move, the connecting arm assembly can drive the clamping arm 2 to move in the opposite direction of the movement of the clamping arm 1, thereby completing the separation or relative translation between the clamping arm 1 and the clamping arm 2. This transmission method is stable and improves the accuracy of the clip device in clamping buttons.

[0011] In the above-mentioned clamping device, the connecting arm assembly includes connecting arm one and connecting arm two, the inner end of connecting arm one and the inner end of connecting arm two are respectively connected to the pushing rod, and the clamping arm two has connecting end one and connecting end two distributed on both sides of the pushing rod, the outer end of connecting arm one is hinged to connecting end one, and the outer end of connecting arm two is hinged to connecting end two.

[0012] The inner end of connecting arm one and the inner end of connecting arm two are connected to the pushing rod, so that connecting arm one, connecting arm two and the pushing rod can move together. Connecting arm one is hinged to connecting end one on clamping arm two, and connecting arm two is hinged to connecting end two on clamping arm two, so that connecting arm one and connecting arm two can drive clamping arm two to move at the same time, thereby increasing the stability of the transmission of the structure and improving the accuracy of clamping buttons on the clip device.

[0016] The width of through slot one is greater than or equal to the width of positioning shaft one, so that positioning shaft one can move in through slot one without obstruction. The width of through slot two is greater than or equal to the width of positioning shaft two, so that positioning shaft two can move in through slot two without obstruction, which facilitates the movement of connecting arm one and connecting arm two, ensures that clamping arm two will not be obstructed during the movement, and increases the precision and accuracy of the movement of clamping arm two.

[0017] In the above-mentioned clamping device, both the connecting arm one and the connecting arm two have a step surface, the inner end of the connecting arm one and the inner end of the connecting arm two are overlapped on the pushing rod in the vertical direction, and the outer ends of the connecting arm one and the connecting arm two are symmetrically distributed on both sides of the pushing rod.

The translational movement stabilizes the movement and increases the accuracy of the clamping arm 1 and the clamping arm 2 in clamping buttons. The two translate away to open the clamping arm 1 and the clamping arm 2, and the two translate toward each other to clamp the clamping arm 1 and the clamping arm 2.
