At this time, the upper side of the clamping column component 2 is coplanar with the upper side of the workbench 1, and then the workpiece is placed on the workbench 1 and / or the clamping column component 2. At this time, the first motor 7 is controlled to drive the bidirectional lead screw 701 to rotate, and the bidirectional lead screw 701 rotates to drive the slider 801 to slide along the slide groove 103, so that the two clamps 8 are close to each other to clamp the workpiece. When it is necessary to clamp a columnar workpiece, the clamp 8 is first controlled to reset, and then the driving component is controlled to drive the clamping column component 2 to rise out of the storage groove 101, so that the clamping column component 2 can be used to clamp the columnar workpiece.

[0028] One side of the clamping plate 8 of the present embodiment is provided with a rubber pad 802, and two rubber pads 802 are located between the two clamping plates 8.

The groove 401 passes through the top plate 4 in the horizontal direction. When in use, the driving component works to push the bottom plate 3 to rise. When the first clamping groove 301 rises above the workbench 1, the first electric push rod 5 is controlled to extend and push the top plate 4 to move upward, and then the columnar workpiece to be clamped is inserted into the second clamping groove 401. At this time, the first electric push rod 5 is controlled to contract and drive the top plate 4 to move downward, and cooperate with the top plate 4 and the first clamping groove 301 to clamp the columnar workpiece. The bottom plate 3, the top plate 4 and the first electric push rod 5 cooperate to facilitate the clamping and fixing of the columnar workpiece.
