DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present application is described in detail below in conjunction with the accompanying drawings. The description in this section is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present application.

[0024] like Figure 1 The first embodiment of the present application is shown, which includes a welding gun body 100 and an electrically heated welding gun head 200 disposed on one side of the welding gun body 100, wherein a first cavity 110 is disposed in the welding gun body 100. In the present embodiment, the welding gun head 200 is made of a metal conductor material, and an electric heating wire is disposed therein. A wire connected to the electric heating wire is disposed in the welding gun body 100, and a power adapter connected to the wire is disposed at one end of the outer side of the welding gun body 100. The power adapter is connected to an external 220V AC power to heat the welding gun head 200. In the present embodiment, the heating temperature of the welding gun head 200 is 350°C. In other embodiments, the heating temperature of the welding gun head 200 may also be other temperatures that melt the welding wire.

[0025] The welding gun head 200 is provided with a first through hole groove 210 for installing a welding wire along the central axis direction, the first through hole groove 210 communicates the inside and outside of the welding gun head 200, and the first through hole groove 210 is connected to the first cavity 110. In this embodiment, the whole welding wire is broken and inserted into the first through hole groove 210. In a preferred embodiment, the aperture size of the first through hole groove 210 is larger than the diameter of the welding wire, so that the welding wire can be inserted into the first through hole groove 210.

[0026] When an external power source is turned on, the welding gun head 200 can be heated and the welding wire can be melted into liquid solder.

[0027] A movable propulsion mechanism 300 is disposed in the first cavity 110, and a pressing mechanism 400 is disposed on the outer side of the welding gun body 100 corresponding to a side of the propulsion mechanism 300. Pressing the pressing mechanism 400 pushes the propulsion mechanism 300 away from the end of the pressing mechanism 400 and extends into the first through hole groove 210, and pushes the liquid solder to flow out of the welding gun head 200.

[0028] In a preferred embodiment, a fixing column 500 perpendicular to the extending direction of the first cavity 110 is fixed in the first cavity 110 corresponding to the pressing mechanism 400, and the two ends of the fixing column 500 are respectively fixed to the top surface and the bottom surface of the first cavity 110. For example, if the welding gun body 100 is placed horizontally, the first cavity 110 is horizontally arranged, and the fixing column 500 is vertically arranged. That is, in this preferred embodiment, the fixing column 500 cuts off and blocks one end of the first cavity 110.

[0029] A second cavity is defined in the fixing column 500 , and a first opening is defined on one side of the fixing column 500 close to the pressing mechanism 400 . One end of the pressing mechanism 400 is inserted into the second cavity through the first opening.

[0030] The propulsion mechanism 300 includes a pair of transmission rods 310, a first limiting rod 320, a second limiting rod 330 and a plurality of scissor frames 340; in the preferred embodiment, one set of scissor frames 340 is included, and in other embodiments, the scissor frames 340 may include a plurality of sets, and when a plurality of sets of scissor frames 340 are included, each set of scissor frames 340 is connected in series. The two ends of a set of scissor frames 340 close to the fixed column 500 are rotatably connected to a pair of movable rods 350, and the two ends of a set of scissor frames 340 close to the welding gun head 200 are rotatably connected to the ends of a pair of transmission rods 310; in the preferred embodiment, since only one set of scissor frames 340 is included, one end of the scissor frames 340 is connected to a pair of movable rods 350 and the other end is connected to a pair of transmission rods 310. Preferably, in the preferred embodiment, one set of scissor frames 340 includes two connecting rods 341 whose middle parts are rotatably connected by an axle pin, and the two connecting rods 341 are connected in an X-shaped arrangement. The two connecting rods 341 rotate around the axle pin connected in the middle thereof. In the preferred embodiment, the fixing column 500 is provided with a through hole corresponding to the connecting rod 341 extending into the second cavity, so that the connecting rod 341 extends into the second cavity and is connected with the movable rod 350 .

[0031] A pair of movable rods 350 are relatively arranged in the fixed column 500 along a direction parallel to the extension direction of the fixed column 500. In the preferred embodiment, the pair of movable rods 350 are relatively vertically arranged in the fixed column 500. After reducing the spacing between the pair of movable rods 350, the spacing between the ends of the two connecting rods 341 on the same side of a set of scissor frames 340 connected thereto is reduced. Since the two connecting rods 341 are cross-connected in an X shape, the spacing between the two ends of the other side of the two connecting rods 341 is also reduced. Moreover, since the ends of the connecting rods 341 on one side connected to the movable rods 350 cannot move horizontally due to being connected in the third chamber, the ends of the two connecting rods 341 away from the movable rods 350 are horizontally moved to the left due to the reduced spacing, that is, the scissor frames 340 are horizontally moved to the left, that is, the scissor frames 340 are pushed to move to the side away from the movable rods 350.

[0032] A pair of movable rods 350 are arranged in the second cavity in a direction parallel to the extending direction of the fixed column 500. One of the movable rods 350 close to the pressing mechanism 400 is connected to the pressing mechanism 400. Reducing the distance between the pair of movable rods 350 pushes a group of scissor frames 340 to move to a side away from the movable rods 350. Preferably, the pair of movable rods 350 are set as a first movable rod 351 and a second movable rod 352. The first movable rod 351 is connected to the pressing mechanism 400, and the second movable rod 352 is placed on a surface in the second cavity away from the pressing mechanism 400. A spring 600 is connected between the pressing mechanism 400 and the second movable rod 352. One end of the spring 600 is connected to one end of the second movable rod 352 away from the pressing mechanism 400, and the other end is connected to the end of the pressing mechanism 400 close to the first movable rod 351. When the pressing mechanism 400 is pressed downward, the first movable rod 351 moves downward, the spring 600 contracts, and the second movable rod 352 moves upward, thereby reducing the distance between the pair of movable rods 350. When the pressing mechanism 400 is released, the spring 600 recovers, pulling the first movable rod 351 and the second movable rod 352 to move in opposite directions, thereby expanding the distance between the pair of movable rods 350. Preferably, the pressing mechanism 400 includes a button 410 and a pressing rod 420, wherein the button 410 is disposed outside the welding gun body 100, one end of the pressing rod 420 is fixed to the middle of the button 410, and the other end is connected to the end of the first movable rod 351 after passing through the first opening, and is also connected to the spring 600.

[0033] The second limiting rod 330 is movably arranged in the first cavity 110 along a direction parallel to the fixed column 500, that is, the second limiting rod 330 is arranged perpendicular to the direction of the first cavity 110. In this preferred embodiment, the first limiting rod 320 and the second limiting rod 330 are arranged perpendicular to each other to form a T-shape. In this preferred embodiment, the second limiting rod 330 is arranged perpendicular to the overall moving direction of the propulsion mechanism 300 to ensure that the sliding direction of the propulsion mechanism 300 is always on the central axis of the first cavity 110, thereby realizing the smooth movement of the propulsion mechanism 300 in the first cavity 110, that is, the second limiting rod 330 plays a role of horizontal limiting on the movement of the scissor frame 340.

[0034] The ends of the pair of transmission rods 310 away from the scissor frame 340 can be rotatably connected to the middle of the second limiting rod 330, the first limiting rod 320 is vertically fixed to the middle of the side of the second limiting rod 330 away from the transmission rod 310, and the end of the first limiting rod 320 away from the second limiting rod 330 can be movably extended into or extended from the first through hole slot 210. The transmission rod 310 and the first limiting rod 320 are both connected to the middle of the second limiting rod 330 to ensure that the movement of the pair of transmission rods 310 is based on the middle of the second limiting rod 330 as a support point and moves along the horizontal center line of the second limiting rod 330.

[0035] Preferably, in order to enable the second limiting rod 330 to move horizontally smoothly and steadily in the first cavity 110: a pair of first grooves are arranged inwardly on the relative inner walls corresponding to the two ends of the second limiting rod 330 in the first cavity 110, and the extension direction of the first grooves is parallel to the extension direction of the first limiting rod 320; a protrusion is arranged at the end of the second limiting rod 330 corresponding to the first groove, and the protrusion can be slidably engaged in the first groove.
