A plurality of pads 10 are installed on one side of the sheet metal workpiece 8, and the bottom end of the connecting plate 9 passes through the bottom end of the sheet metal workpiece 8 and extends to the bottom of the sheet metal workpiece 8. A bidirectional threaded rod 3 is installed on one side of the base 1 through a bearing, and one end of the bidirectional threaded rod 3 passes through the other side of the bidirectional threaded rod 3 and is connected to a rotating handle 12. Two threaded blocks 2 are sleeved on the outer side of the bidirectional threaded rod 3, and the top of the threaded block 2 is connected to a connecting block 15 by welding, and the top of the connecting block 15 passes through the top of the base 1 and is connected to the bottom end of the connecting plate 9.

[0020] The shape of the connecting plate 9 is L-shaped, and the two connecting plates 9 are symmetrical about the vertical center axis of the bidirectional threaded rod 3;

[0021] The punch 6 and the cushion block 10 are located at the same height, and one end of the cushion block 10 is provided with a groove having the same diameter as the outer side of the punch 6, and the punch 6 and the cushion block 10 are located in the same vertical plane;

[0022] The shape of the thread block 2 is square, and the bottom end of the thread block 2 is in contact with the bottom end of the inner part of the base 1;

[0023] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, during the use of the device, the sheet metal workpiece 8 can be placed on the top of the base 1, and the connecting plate 9 can be inserted into the inside of the sheet metal workpiece 8. Then, by utilizing the existence of the rotating handle 12, the bidirectional threaded rod 3 can be rotated under the action of manually rotating the rotating handle 12. Through the rotation of the bidirectional threaded rod 3 and the restriction of the inner wall of the base 1, the two threaded blocks 2 can be horizontally moved in opposite directions on the outside of the bidirectional threaded rod 3, so that the connecting plate 9 can be driven to move horizontally through the connecting block 15, so that the distance between the two connecting plates 9 can be flexibly adjusted, so that the connecting plate 9 can be moved from the inside of the sheet metal workpiece 8 through the connecting plate 9.
