The drop type fuse protector comprises a body and a fusion tube, wherein the fusion tube comprises a tube body, a fuse wire, an upper base, a lower base, an upper moving contact and a lower moving contact, and also comprises a fuse wire tensioning device and a ball head, wherein the fuse wire tensioning device comprises a locking spring plate and a reset spring; a wire clamping groove is formed in one end of the locking spring plate, one end of the locking spring plate is folded, and the other end of the locking spring plate can clamp a limiting angle on the lower base; an operation ring is further arranged on the upper base; and a buckle is arranged at the end, connected with the fuse wire tensioning device, of the fuse wire. The drop type fuse protector is further provided with a reflector. The invention also relates to an operation tool, wherein the operation tool comprises a curved groove matched with the ball head. The curved groove is matched with the ball head, and the reflector is added, so that the drop type fuse protector can be convenient to install; and the fuse wire tensioning device can guarantee the safety of the fuse wire, so that the reliability of power supply is guaranteed.

The invention belongs to the technical field of composite materials, and in particular relates to a high-hardness composite material. From top to bottom, the composite material sequentially includes a first polycarbonate layer, a polymethyl methacrylate layer and a second polycarbonate layer. The upper surface of the polycarbonate layer is printed with a nano-transparent film; its preparation method is: in the first step, in a multi-slit coating device, melted polycarbonate, melted polymethyl methacrylate and melted Polycarbonate is injected into the cooling roller from three adjacent slits at the same time, so that the three molten layers are solidified and formed at one time to obtain the main material; in the second step, the nano transparent film is printed on one of the main material by the roller On the surface. Compared with the existing technology, phenol has the following advantages through the ingenious compounding of PMMA and PC and the use of ingenious production technology: light, high transparency, high light transmittance, high hardness, high transmittance, and suitable haze , Suitable softness, no bending, no cracking.
