[0023] When the device is needed, the worker first places the workpiece on the workbench 2, and then starts the cylinder 3 through the controller 16. The telescopic rod of the cylinder 3 extends downward, pushing the lower pressure rod 4 to move downward, and the hinged rods 6 on both sides are squeezed to slide the clamp 601 toward the workpiece and clamp the workpiece. When the lower pressure rod 4 moves downward, the reamer 5 also moves downward, and the spindle head 501 contacts the workpiece and performs reaming. After the reaming of the workpiece is completed, the telescopic rod of the cylinder 3 is retracted to make the lower pressure rod 4 and the reamer 5 move upward, and the lower pressure rod 4 pulls the hinged rods 6 on both sides to drive the clamp 601 to slide in the opposite direction of the workpiece, and the workpiece can be taken out by detaching from the workpiece. If the next workpiece needs to be reamed, the above operation can be repeated.

[0024] like Figure 1-Figure 4 As shown, the reinforcement assembly includes a sleeve 7, a clamping block 8 and a spring 9. A plurality of the sleeves 7 are installed in a linear array on one side surface of the two clamps 601 close to the reamer 5 by means of screws. The inside of the sleeve 7 is slidably connected to the clamping block 8, and the spring 9 is connected between the plurality of the sleeves 7 and the corresponding clamping blocks 8.

[0025] When an irregular workpiece needs to be clamped, when the clamping plate 601 slides toward the direction of the irregular workpiece, the clamping block 8 comes close to the irregular workpiece surface, and the internal spring 9 is compressed to make the clamping block 8 clamp the irregular workpiece. When the clamping plate 601 slides in the opposite direction of the workpiece, the clamping block 8 is reset and detached from the workpiece by the spring 9.

[0026] like Figure 1 , Figure 2 and 5 As shown, it also includes a chip suction hood 10, a handle 11, a telescopic tube 12, a collection box 13, a sealing cover 1301, a filter 14 and a fan 15.
