[0002] An electric heater is a device that uses electricity as energy. It can convert electrical energy into thermal energy for heating air, water or other media. Electric heaters are widely used in homes, offices, industrial sites, etc. to provide warmth and heating functions.

[0003] At present, in some specific heating conditions, it is necessary to frequently and quickly move, disassemble, and replace electric heaters to complete the heating of different heat-receiving bodies or perform online maintenance on electric heaters; the equipment position is uncertain, and it is necessary to frequently and quickly lift and replace the position. However, the mainstream electric heaters currently used in such conditions mostly use threaded fasteners for limiting and anti-collision fixation. This structure is time-consuming and labor-intensive to disassemble and assemble, which seriously delays production efficiency. For this reason, we propose a limiting and anti-collision structure for electric heaters. Utility Model Content
