This application provides a composite current collector and its preparation method, a negative electrode, and a secondary battery. The composite current collector includes a substrate layer, a transition layer disposed on at least one side of the substrate layer, and a conductive layer disposed on the transition layer. The substrate layer is made of one or more of copper-nickel alloy, copper-tin alloy, and iron-nickel alloy. The elements contained in the transition layer are not entirely the same as those contained in the substrate layer. An elemental gradient diffusion region exists at the interface between the substrate layer and the transition layer. Within this region, the elements contained in the substrate layer and the transition layer diffuse into each other, and their concentrations are distributed in a gradient along the thickness direction. The composite current collector provided by this application has improved interfacial bonding.

This utility model discloses an electric heating tube capable of rapid heating, comprising a mounting plate, a fixing plate below the mounting plate, and an electric heating tube body mounted on the lower end of the fixing plate. The electric heating tube body contains two heat-conducting inner liners and two spiral heating wires, the lower ends of which are fixed together by bent heating wires. The outer wall of the electric heating tube body has multiple outer cylinders, each with an inner cylinder fixedly connected to its inner wall. Each inner cylinder has a heat sink fixedly connected to its outer wall. An mounting block is fixedly connected to the upper end of the fixing plate. The device incorporates a guide rod, a sliding plate, and a spring, among other structures. The electric heating tube is installed and fixed by engaging the limiting block into a limiting groove. This method allows for convenient and simple assembly and disassembly of the electric heating tube without the need for external tools.

This utility model discloses an arc-shaped bevel worm gear reducer device with a clutch function, including a housing, an input shaft, and an output shaft. An arc-shaped bevel worm gear is mounted on the input shaft, and a conical worm wheel is slidably connected to the outer wall of the output shaft, with the arc-shaped bevel worm gear and the conical worm wheel engaging with each other.
