[0007] Preferably, a hexagonal clamping column is fixedly connected in the middle of the main rod.

[0008] Preferably, the two rotary file heads have the same main body structure.

[0009] Preferably, the two rotary file heads are of different models.

[0010] Preferably, the tops of the two rotary file heads are coated with anti-corrosion material.

[0011] Preferably, the hexagonal slot is matched with the hexagonal plug-in rod.

[0012] Preferably, the latch pin is matched with the latch pin slot.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] In the utility model, hexagonal slots are provided at both ends of the main rod, a hexagonal plug-in rod is provided at one end of the rotary file head, and a mounting cavity, a latch, a return spring and a latch groove are also provided, so that the two rotary file heads can be separated from the main rod, which is not only convenient for carrying but also can be replaced with different types of rotary file heads according to needs, thereby increasing the applicability of the device; one main rod can connect two rotary file heads, which greatly reduces the consumption of raw materials and reduces costs.
