[0031] Specifically, the first adjusting member 201 includes a moving plate 201a and a rotating wheel 201b. The moving plate 201a is fixed to the top of the stamping plate 101, and the rotating wheel 201b is rotatably connected to the inner wall of the moving plate 201a through a bearing.

[0032] The setting of the movable plate 201a can drive the stamping plate 101 to move, so that the workpiece can be stamped. When in use, a movable rod will be inserted into the rotating wheel 201b, and the movable rod will be movably connected with the movable plate 201a. The movement of the movable rod can drive the movable plate 201a to move so as to stamp the workpiece. The movable rod will be threadedly connected with the rotating wheel 201b, and the rotation of the rotating wheel 201b can drive the movable rod in the rotating wheel 201b to move. The stamping height of the stamping plate 101 can be adjusted by the movement of the movable rod, so as to stamp workpieces of different heights.

[0033] Specifically, the first adjusting member 201 further includes a rotating rod 201c and a supporting sleeve 201d, the rotating rod 201c is located at one side of the rotating wheel 201b, the supporting sleeve 201d is sleeved on the outside of the rotating rod 201c, and the supporting sleeve 201d and the rotating rod 201c are movably connected.

[0034] Teeth are provided on one side of the rotating wheel 201b, and a thread is provided on the rotating rod 201c. The rotating rod 201c is equivalent to a worm, and the rotating wheel 201b is equivalent to a worm wheel. Through the worm gear transmission, when the rotating rod 201c rotates, the rotating wheel 201b can be driven to rotate. By rotating the rotating wheel 201b, the moving rod in the moving plate 201a can be moved. By moving the moving rod, the height of the stamping plate 101 can be adjusted. The support sleeve 201d is fixed to one side of the moving plate 201a. The rotating rod 201c can be supported by the setting of the support sleeve 201d to prevent the rotating rod 201c from deviating.

[0035] Specifically, the driving member 202 includes a sprocket 202a and a chain 202b. The sprocket 202a is fixed to one end of the rotating rod 201c, and the chain 202b is sleeved on the outside of the sprocket 202a.

[0036] There are two sprockets 202a, which are respectively fixed to one end of the two rotating rods 201c. The rotation of the sprocket 202a can drive the two rotating rods 201c to rotate simultaneously, and the setting of the chain 202b can drive the two sprockets 202a to rotate simultaneously.

[0037] Specifically, the driving member 202 further includes a motor 202c and a fixing plate 202d. The motor 202c is located at the bottom of the chain 202b, and the fixing plate 202d is sleeved on the outside of the motor 202c.

[0038] The rotation of the motor 202c can drive the chain 202b to rotate. By setting the motor 202c between the two sprockets 202a, the force points of the chain 202b transmission can be more uniform, so that the force applied to the stamping plate 101 when adjusting the height can be more uniform. The fixed plate 202d is fixed to the inner wall of the support frame 102. The setting of the fixed plate 202d can support the motor 202c to prevent the motor 202c from offset.

[0043] During use, when it is necessary to stamp workpieces of different heights, the height of the stamping plate 101 needs to be adjusted. By starting the motor 202c, the rotation of the motor 202c can drive the chain 202b to rotate. By arranging the motor 202c between the two sprockets 202a, the force points of the chain 202b transmission are more uniform, so that the force applied to the stamping plate 101 when adjusting the height can be more uniform. The rotation of the chain 202b can simultaneously drive the two sprockets 202a to rotate. The rotation of the sprocket 202a can drive the two rotating rods 201c to rotate at the same time. When the rotating rod 201c rotates, the rotating wheel 201b can be driven to rotate. The rotating rod in the movable plate 201a can be moved by the rotation of the rotating wheel 201b. The movement of the movable rod drives the movable plate 201a to move. The movement of the movable plate 201a drives the stamping plate 101 to move. The height of the stamping plate 101 is adjusted to allow stamping of workpieces of different heights.

[0044] When the tightness of the chain 202b needs to be adjusted, the user presses the pressure plate 203c, and the pressure plate 203c moves, driving the movable plate 203b to move. The movement of the movable plate 203b can drive the adjustment block 203a to move. The movement of the movable plate 203b drives the adjustment block 203a to move. The movement of the adjustment block 203a drives the chain 202b to move, thereby adjusting the tightness of the chain 202b. After the tightness of the chain 202b is adjusted, the movable plate 203b is fixed to one side of the fixed plate 202d by bolts, thereby preventing the movable plate 203b from moving on its own.
