The support table 11 in the support unit 10 is parallelly and slidably installed on the base. The loading and unloading platform 20 is parallel and fixedly installed on the support table. A positioning block 12 is slidably provided on the loading and unloading platform 20. The gear transmission unit 30 is located on the support table and on one side of the positioning block 12. The adjusting cross bar 13 is located above the loading and unloading platform, the clamping unit 40 is installed on the adjusting cross bar and the clamping unit is located directly above the gear transmission unit 30, the cutting unit 50 and the positioning block 12 are respectively located on both sides of the gear transmission unit, when the graphite square material is placed on the gear transmission unit 30, the clamping unit 40 presses the graphite square material from the top of the graphite square material, and the positioning block 12 presses the graphite square material from the side of the graphite square material, during the cutting process, the graphite square material rotates with the gear transmission unit 30, and the cutting unit 50 cuts the graphite square material from the other side of the graphite square material to cut it into round rods.

The rotating shaft of the rotating motor is connected to the driving gear, and the gear plate is meshed with the passive gear. Therefore, the rotating motor rotates to drive the driving gear to rotate, the driving gear drives the passive gear to rotate, the passive gear drives the gear plate to rotate, and the gear plate drives the graphite square material to rotate to complete the operation of cutting into round rods. This gear transmission unit is a conventional technology in this field and is not shown in detail in the figure.
