The control unit 23 has a shaft assembly 231 that penetrates through the center of the fixed seat 211 through an arc-shaped sliding groove 2211, two gaskets 232 sleeved on the shaft assembly 231, a guide pin 233 inserted on the shaft assembly 231, And a cam handle 234 sleeved at the end of the shaft assembly 231, the cam handle 234 is provided with a helical groove 2341 along the outer periphery for the guide pin 233 to be inserted along, when the user turns the cam handle 234 counterclockwise , the cam handle 234 presses against the clamping plate 212 through the gasket 232, so that the clamping plate 212 and the fixing seat 211 can be clamped together to fix the supporting plate 221. When the user turns the cam handle 234 clockwise, the cam handle 234 unclamps the clamping plate 212 and the supporting plate 221 at once, so that the supporting plate 221 can move up and down along the fixed seat 211.

Although the above pallet device 20 also has the function of disassembling and assembling the pallet 221, there are still problems in use. The cam handle 234 uses the spiral groove 2341 to push the guide pin 233 to drive the shaft assembly 231 to move, so as to control the tightness of the clamping plate 212. Although this spiral groove 2341 structure has the effect of forcing and compressing the clamping plate 212, the cam handle 234 may be shaken loose under the vibration of the long-term cutting operation, and the clamping plate 212 has no way to support the supporting plate 221. It is completely locked, so it still cannot completely solve the problem of poor fixing effect.
