[0024] Example 1, by Figure 1 The present invention relates to a composite heating film structure, including a heating film body 1, an electric wire 3 on the outer side of the heating film body 1, a plug 4 fixedly connected to one end of the electric wire 3, and a connecting mechanism 2 between the electric wire 3 and the heating film body 1, which connects the plug 4 to a power source, so that the heating film body 1 can perform heating through the electric wire 3.

[0025] Specifically, by Figure 2-4The connecting mechanism 2 includes a connecting end 201 fixed to the top of the heating film body 1. A vertical cylinder 203 is fixedly connected to the top of the connecting end 201. A fixed end 202 is fixedly connected to the end of the wire 3 away from the plug 4. The fixed end 202 is placed on top of the connecting end 201 and is located inside the vertical cylinder 203. Two guide posts 205 are symmetrically fixedly connected to the top of the connecting end 201. The vertical cylinder 203 is located between the two guide posts 205. An arc-shaped plate 204 is movably sleeved on the outer side of each of the two guide posts 205. The two arc-shaped plates 204 fit together and are located on the outer side of the vertical cylinder 203. A pressure block 2011 is fixedly connected to the inner side of 204. Both pressure blocks 2011 abut against the top of the fixed end 202. The vertical cylinder 203 is provided with a relief groove 207. The wire 3 passes through the relief groove 207.

A screw sleeve 208 is provided on the outer side of the vertical cylinder 203. The screw sleeve 208 is located on the top of the two arc plates 204. Multiple auxiliary handles 209 are evenly fixedly connected to the outer side of the screw sleeve 208. An external thread 206 is provided on the outer side of the vertical cylinder 203. The screw sleeve 208 is threaded onto the outer side of the vertical cylinder 203 through the external thread 206.

[0026] In use, first place the fixed end 202 inside the vertical cylinder 203, so that the fixed end 202 is inside the connecting end 201, and the clearance groove 207 avoids the wire 3. Then, the two arc-shaped plates 204 are fitted together on the outside of the vertical cylinder 203, while the two pressure blocks 2011 pass through the two sliding grooves 2010 and are positioned above the fixed end 202. Then, the two arc-shaped plates 204 are moved downwards and fitted onto the outside of the two guide posts 205, until the two pressure blocks 2011 are both abutting the top of the fixed end 202. Finally, the screw sleeve 208 is fitted onto...

When the rotating screw sleeve 208 is disengaged from the outside of the vertical cylinder 203, move the two arc plates 204 upward and disengage them from the two guide posts 205 respectively. Then move the two pressure blocks 2011 out of the vertical cylinder 203, and the fixed end 202 can be removed from the vertical cylinder 203 to complete the disassembly of the wire 3. Finally, the disassembly and assembly of the wire 3 are realized.
