[0003] In the prior art, for a hand-held resistance welding torch used for cold welding repair, in order to be convenient for holding, the gun body is relatively small and is not water-cooled. During the working process, due to continuous resistance welding heat generation, the gun body becomes hot after being used for a period of time, resulting in the inability to hold it by hand, affecting normal use and reducing the use efficiency. Content of the Utility Model

Through the cold water pipe groove arranged on the outer wall of the shell, when the repair welding torch is used for a long time, it can be cooled by the cold water in the cold water pipe groove, and the cold water fills the water-cooling sleeve, so that the temperature reduction of the rotating shaft is more sufficient, thereby improving the service life of the components. At the same time, through the wrapping of the water-cooling sleeve, water leakage can also be avoided, resulting in the conduction of the rotating shaft.

[0007] Preferably, a rotating connection head and a plug connection head for transmission are arranged between the motor and the rotating shaft. The rotating connection head is fixedly connected to the output end of the motor, and the plug connection head is drivingly connected to one end of the rotating shaft.

[0008] Through the above technical solution, through the connection of the rotating connection head and the plug connection head, the motor can transmit the torque force to the rotating shaft, thereby driving the rotating shaft to rotate.

[0009] Preferably, an inner sleeve for wrapping the rotating shaft is fixedly connected inside the water-cooling sleeve, and a bearing is arranged between the rotating shaft and the inner sleeve.

[0010] Through the above technical solution, the protection of the inner sleeve can make the rotating shaft more stable during operation, and the bearing can reduce the friction force of the rotating shaft during rotation.

[0011] Preferably, a snap ring is provided between the outer wall of the bearing and the rotating shaft, and a spring is provided at the bottom of the rotating shaft.

[0012] Through the above technical solution, the snap ring can play a role in fixing the rotating shaft, and through the setting of the spring, the vibration force of the rotating shaft during operation can be reduced.

[0013] Preferably, one end of the rotating shaft away from the motor is fixedly connected with a welding head, and the outer wall of the welding head is fixedly connected with a welding core.

[0014] Through the above technical solution, the welding core can be installed through the welding head, thereby achieving the effect of facilitating welding.

[0016] 1. By opening a cold water pipe groove on the outer wall of the housing, when the repair welding torch is used for a long time, it can be cooled by the cold water in the cold water pipe groove, and the cold water fills the water cooling sleeve, so that the cooling of the rotating shaft is more sufficient, thereby improving the service life of the components. At the same time, through the wrapping of the water cooling sleeve, it can also prevent water leakage and cause the rotating shaft to conduct electricity.

[0017] 2. Through the connection of the rotating joint box and the plug connector, the motor can transmit the torque force to the rotating shaft, thereby driving the rotating shaft to rotate.
