In the figure: 1. Arch ring 2. Connector board 3. Screw hole 4. Connector 5. Retaining ring.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

As shown in the figure, a detachable screw heating ring includes an arch ring 1, a connector board 2, a screw hole 3, a connector plug 4 and a retaining ring 5, retaining rings 5 are installed on both sides of the arch ring 1, and the arch ring 1 is used for arranging wires, and the bottom of arch ring 1 is provided with a connector board 2, which is provided with a plurality of plugs 4 for connecting multiple heating wires, so that when the upper and lower arch rings 1 are closed, through Connector board 2 connects the wires up and down and heats the screw rod; both sides of connector board 2 have screw holes 3 for fixing when up and down are combined.

Both the arch ring 1 and the retaining ring 5 are semicircular.

The arch ring 1 is made of titanium alloy.

How to use this device: Fix the upper and lower arch rings 1 on the screw rod through the screw hole 3. When the heating ring is broken after a long time of use, you can directly remove the upper and lower arch rings 1 and replace them with new ones. The entire barrel and screw are disassembled to replace the heating ring, which is simple and convenient.
