[0002] Fuse brackets are an important accessory in power systems. Their main function is to install and support fuses, protecting the power system from damage caused by faults. When there is an overload or short circuit, the fuse will automatically disconnect the circuit, protecting the system from damage caused by excessive current.

[0003] Existing fuses are generally fixed to fuse brackets by end seats and screws at both ends. When a fuse is damaged and needs to be removed and replaced, tools are first needed to disconnect the wires on the end seats at both ends of the fuse, and then the screws on the end seats at both ends of the fuse are removed to remove the fuse for replacement. Then, the new fuse is fixed and installed again by screws in the same way. The removal and replacement of fuses is relatively troublesome and inconvenient, and the screws are easy to fall off and be lost during the tightening process, resulting in poor performance.
