Description

Fuse convenient to overhaul Technical Field The utility model relates to the technical field of fuses, in particular to a fuse convenient to overhaul. Background The fuse is an electric appliance which uses a metal conductor as a melt to be connected in series in a circuit, and fuses due to self-heating when overload or short-circuit current passes through the melt, so that the circuit is disconnected, the fuse has a simple structure, is convenient to use, and is widely used as a protection device in a power system, various electrical equipment and household appliances. When current fuse is dismantling, because its fixed knot constructs comparatively firm, singly lean on the staff hardly to dismantle, often need additionally with the help of a extracting tool, with the fuse holder back through this instrument, just can the level be pulled and dismantle the fuse, and when dismantling or installing the fuse at every turn, all need this kind of instrument, it is not enough convenient, consequently, in order to make the installation or dismantle of fuse more convenient, provide a fuse convenient to overhaul. Disclosure of utility model The utility model aims to solve the problems that the traditional fuse can be operated only by external tools when being installed or disassembled, and is tedious in the past and is not discerned, and provides the fuse which is convenient to overhaul. The utility model provides a fuse convenient to overhaul, which comprises a ceramic fuse body, a metal top plate and a fixed block, wherein the front surface of the ceramic fuse body is horizontally provided with a movable notch, the inside of the movable notch is horizontally distributed with a metal handle and a magnetic stripe, both ends of the metal handle are rotationally connected to the upper side and the lower side of the inner wall of the movable notch, and the metal handle is used for a user to pull the ceramic fuse body in a handheld manner to mount or dismount the ceramic fuse body; The magnetic stripe is horizontally fixed in the middle of the inner wall of the movable notch and is used for adsorbing and fixing the metal handle. As still further scheme of the utility model, the fixing block is vertically fixed on the top of the metal top plate and is used for fixing the ceramic fuse body; The metal top plate is vertically arranged at the top of the ceramic fuse body, the number of the metal top plate and the number of the fixing blocks are two and symmetrically distributed at the upper end and the lower end of the ceramic fuse body, and the rotating shaft structures at the two ends of the metal handle penetrate through and are distributed in the ceramic fuse body and the metal top plate, so that the stability of the metal handle structure is maintained.
