It should be noted that in the description of the present invention, the terms of direction or positional relationship indicated by the terms "upper", "lower", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, which are merely for convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

As shown in fig. 1 to 4, the utility model relates to a take pneumatic clamping jaw of spring buffering, it includes drive base 1, a pair of digging arm 2, a pair of clamping jaw 4, and this drive base 1 has upper end and lower extreme, and drive base 1's upper end adaptation connects the power supply, realizes drive base 1 oscilaltion etc.. The pair of movable arms 2 are respectively arranged on the left side and the right side of the lower end of the driving base 1 and controlled by the driving base 1 to form the movement of left and right opening and closing tracks; in this embodiment, the upper end of the movable arm 2 is connected to the driving base 1 in a hinged manner, so that the opening and closing end of the movable arm 2 can be opened and closed relatively to the hinged position. The pair of clamping jaws 4 are respectively assembled at the opening and closing ends of the pair of movable arms 2, and the clamping jaws 4 have the vertical floating characteristic relative to the movable arms 2. The design can effectively optimize the assembly structure, is convenient to manufacture and has the buffering effect. When the corresponding holes of the pins of the plug-in unit and the PCB are not aligned due to certain factors, the plug-in unit is clamped by the clamping jaw 4 and continuously descends, the pins of the plug-in unit are contacted with the non-hole positions of the PCB, the force of the PCB, which acts on the clamping jaw in the opposite direction, enables the clamping jaw to float relative to the movable arm, and reduces the force borne by the pins of the plug-in unit, so that the plug-in unit and the PCB can be protected, the plug-in unit and the PCB are prevented from being damaged, and unnecessary waste.
