[0007] Further, two linear modules are fixedly installed on the upper surface of the support frame, the two linear modules are connected with one fixed seat, and each fixed seat is fixedly connected with the connecting rod close to it.

[0008] Through the above-mentioned scheme, the linear module drives the fixed seat to move along the axial direction, the sliding column slides in the sliding groove of the cam plate, the linear motion is converted into the rotary motion of the cam plate, and finally the synchronous angle adjustment of the two groups of clamping jaws is realized.

[0009] Further, a fixed plate is arranged on one side surface of the support frame, one group of guide rails is fixedly installed on the side of the fixed plate close to the support frame, and the support frame is slidably connected with the group of guide rails.

[0010] Through the above scheme, the up and down movement of the support frame can be limited, and the sliding cooperation of the guide rail and the support frame ensures the linearity of the lifting movement, so that the clamping jaw main body can clamp the battery cell, and the equipment operation stability is improved.

[0011] Further, one side of the fixed plate close to the support frame is provided with a power seat, and an electric push rod is arranged in the power seat.
