[0029] The effect achieved by the entire embodiment 1 is that, first, two circulation pumps 210 are fixedly connected to the outer wall of the central joint body 208, and the two circulation pumps 210 are connected to the interior of the circulation cavity 209. When one of the circulation pumps 210 transports the water after cooling to the interior of one of the circulation cavities 209, the cooling water can be kept circulating inside the welding mechanism 1 and the water cooling mechanism 2, and transported out under the absorption of the other circulation pump 210, thereby ensuring that the cooling water forms a complete circulation inside the device.

[0030] Embodiment 2, as Figure 2-Figure 4 As shown, the welding mechanism 1 includes a welding head body 101, a circulation chamber 102 is opened inside the welding head body 101, two movable movable grooves 103 are opened on the outer wall of the welding head body 101, a clamping groove 104 is opened on one side of the inner wall of the two movable movable grooves 103, and a threaded groove 105 is opened on the bottom of the inner wall of the two clamping grooves 104.
