[0025] When in use, the sliding sleeve 3 is sleeved on the outside of the column 2, so that the double-rod cross frame 4 and the milling cutter 9 can move up and down, the slider 5 is sleeved on the outside of the double-rod cross frame 4, so that the milling cutter 9 can move, and the drive motor 7 is used to drive the milling cutter 9 to rotate. When the electric heating wire 803 is working, it heats the milling cutter 9 connected to the rectangular groove 802 through magnesium oxide powder 804.

[0026] For example, Figure 3 As shown, the present invention further includes a power storage box 101 embedded inside the base 1 , and a current output end of the power storage box 101 is electrically connected to the current input end of the drive motor 7 and the electric heating wire 803 through a power line.

[0027] When in use, the power storage box 101 supplies power to the driving motor 7 and the electric heating wire 803, so that the device does not need to be connected to an external power supply.

[0028] For example, Figure 3 As shown, the present invention also includes a reserved groove 102 at one end of the base 1, screws 103 are connected to the top two ends of the base 1 through threaded grooves, and a rubber block 104 is glued to the bottom end of the screw 103 located inside the reserved groove 102.

[0037] The operator turns on the drive motor 7 and drives the milling cutter 9 to rotate at high speed through the docking sleeve 8. The operator holds the first handle 12 with one hand and moves the double-rod cross frame 4 and the high-speed rotating milling cutter 9 downward through the sliding sleeve 3 to drill the inner panel of the back door. The operator holds the second handle 13 with the other hand and moves the high-speed rotating milling cutter 9 through the sliding block 5 to groove the inner panel of the back door.

[0038] When grooving the tailgate inner panel made of plastic material, first power is supplied to the electric heating wire 803, and the electric heating wire 803 is heated after being energized. The magnesium oxide powder 804 transfers the heat generated by the electric heating wire 803 to the stainless steel sleeve 801, and heats the milling cutter 9 connected to the stainless steel sleeve 801 through the rectangular groove 802. When the heated milling cutter 9 is used to groove the tailgate inner panel made of plastic material, burrs are less likely to be generated.
