[0019] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the specific protection scope claimed by the present utility model.

[0020] Such as Figures 1-4As shown in the figure, a high-strength metal fitting includes a gear body 1. A heat dissipation annular groove 2 is formed on one side of the gear body 1. A plurality of teeth are arranged on the outer wall of the gear body 1 along the circumferential direction. A first heat dissipation plate 4 is fixedly penetrated through one side of the teeth. One side of the first heat dissipation plate 4 extends into the heat dissipation annular groove 2. A detachable protective sleeve 6 is arranged on the outer wall of the gear body 1, which can effectively protect the gear teeth and does not affect the meshing between gears. The protective sleeve 6 is installed by sleeving on the teeth and fixed to the side of the gear through bolts, avoiding the wear of the teeth and improving the strength of the gear. When the protective sleeve 6 is damaged, the protective sleeve 6 can be replaced, and there is no need to replace the whole gear, which can also effectively reduce the cost. The protective sleeve 6 cooperates with the gear body 1 and the teeth and can completely cover the gear body 1. A plurality of fan blades 10 are fixed on the inner wall of the heat dissipation annular groove 2. A plurality of first heat dissipation holes 7 communicating with the heat dissipation annular groove 2 are formed on one side of the gear body 1. A plurality of second heat dissipation holes 8 communicating with the heat dissipation annular groove 2 are formed on the side wall of the protective sleeve 6. The structure is simple. The arranged protective sleeve 6 effectively improves the strength of the gear body 1 and the teeth and plays a role in protecting the teeth. At the same time, the tooth sleeve can be quickly disassembled from the gear body 1, which is convenient for people to maintain it. The arranged first heat dissipation plate 4, the first heat dissipation plate 4 and the second heat dissipation plate 5 are prior arts and can be found on Baidu. The heat dissipation plates are usually located at the bottom and top of the main board of a laptop computer and are made of metal materials such as aluminum or copper. These materials have good thermal conductivity. The larger the area of the heat dissipation plate, the higher its conduction efficiency and the more effectively it can dissipate heat. It can dissipate heat from the teeth and the protective sleeve 6. The arranged fan blades 10 can rotate the fan blades 10 when the gear body 1 rotates, allowing external gas to enter the heat dissipation annular groove 2, taking away the heat of the first heat dissipation plate 4 and then discharging it. It is relatively perfect and improves the service life of the gear body 1. Reinforcing ribs 3 are arranged inside the heat dissipation annular groove 2, improving the strength of the gear body 1. It is relatively practical. Second heat dissipation plates 5 connected to the first heat dissipation plate 4 are penetrated through both sides of the teeth. One side of the first heat dissipation plate 4 and the second heat dissipation plate 5 is in contact with the inner side of the protective sleeve 6, improving the cooling effect on the protective sleeve 6. The protective sleeve 6 is fixed to the gear body 1 through bolts, facilitating the installation, fixation and disassembly of the protective sleeve 6. The protective sleeve 6 is made of high-alloy steel material, improving the strength of the protective sleeve 6;

[0021] As Figures 1-3 shown, a connection hole 9 is formed on one side of the gear body 1, facilitating the connection with an external pin shaft.

[0022] The working principle of the present utility model is as follows: When in use, the protective sleeve 6 is put on the gear body 1 and then fixed by bolts, which can effectively increase the strength of the gear body 1; the first heat dissipation plate 4 and the second heat dissipation plate 5 provided can cool the gear body 1 and the protective sleeve 6. When the gear rotates, it can drive the fan blade 10 to rotate. The fan blade 10 can inhale the external air into the heat dissipation annular groove 2 and then discharge it, thereby cooling the first heat dissipation plate 4, improving the heat dissipation effect of the gear body 1, and also increasing the service life of the gear body 1.

[0023] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model are implemented according to the conventional means in the art without special explanation and limitation.
