[0029] When in use, the screw rod 12 is driven to rotate by rotating the knob 11, and the slider 13 is driven to move up and down. Round rods 14 are fixedly installed on both sides of the slider 13. The round rods 14 and the round rods 1401 are fixedly connected by levers 16.

At the same time, the adjustment process is smoother when the knob 11 is used for adjustment.

[0030] The locking mechanism includes a rotating rod 19, a motor 20, a clamping plate 21, a clamping claw 22, a slider three 23, a gear one 24 and a scroll plate 25. The rotating rod 19 is rotatably mounted on the center of one side of the slider two 18, and the rotating rod 19 penetrates the slider two 18 and extends inwardly. The motor 20 is fixedly connected to one side of the rotating rod 19, and the clamping plate 21 is fixedly mounted on the side of the rotating rod 19 away from the motor 20. Three groups of slide grooves two 201 are arranged on the top of the clamping plate 21, and the clamping claw 22 is slidably mounted inside the slide grooves two 201. Three groups of sliders three 23 are fixedly mounted on the bottom of the clamping claw 22. The scroll plate 25 is slidably mounted on the surface of the slider three 23.

Since the clamping jaws 22 are slidably installed in the top slide groove two 201 of the clamping plate 21, the travel trajectory of the clamping jaws 22 is limited. Since the clamping plate 21 is rotatably connected to the motor 20 through the rotating rod 19, the clamping plate 21 is driven to rotate as a whole. Using this fixing method, the fixation is more reliable, and the rotor shafts of different sizes can be fixed and rotated at the same time, so that the processing is more uniform and the application range is greatly increased.

[0032] Working principle: first, turn knob 11 to adjust slider 2 18 to the desired position, then turn knob 2 1101 to adjust clamping claw 22 to fix the rotor shaft to be processed, turn on the motor 20 to drive the clamping plate 21 to rotate, and then cooperate with the grinder 10 at the bottom of the electric telescopic rod 9 to process the rotor shaft. During the processing, turn on the fan 28 to form negative pressure inside the T-shaped pipe 4 and the funnel 3, and collect the metal chips and dust generated by the production into the collection box 6. The collection box 6 can be pulled out with the handle 5, which is convenient for the treatment of metal chips and dust generated by subsequent processing.
