Two opposite sides of the pneumatic clamping finger are provided with two connecting rotating shafts 511 corresponding to the number of the first arc-shaped grooves 541 and the second arc-shaped grooves 542. It can be understood that the pneumatic clamping finger is connected with the first arc-shaped groove 541 and the second arc-shaped groove 542 in a sliding manner through the connecting rotating shaft 511, so that rolling friction is generated between the pneumatic clamping finger and the groove walls of the first arc-shaped groove 541 and the second arc-shaped groove 542 during the movement process of the pneumatic clamping finger, and the smoothness of the movement of the pneumatic clamping finger is improved. It should be noted that the pneumatic clamp fingers are not described in detail in the prior art.
