[0020] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0022] like Figure 1 and Figure 2 As shown, the electrode holder of this example includes an upper electrode holder 1 and a lower electrode holder 2, the cross section of the upper electrode holder 1 and the lower electrode holder 2 is an L-shaped structure, and the longitudinal section is a straight-line structure. The two are used together and are both integrally formed structures.

[0023] like Figure 3 and Figure 4 As shown, the upper electrode holder 1 and the lower electrode holder 2 are provided with an upper protrusion 5 and a lower protrusion 6 at the bottom and the top, respectively. The upper protrusion 5 and the lower protrusion 6 are both triangular structures. The upper protrusion 5 and the lower protrusion 6 are provided with insertion grooves 7 at the bottom and the top, respectively. The insertion grooves 7 between the two are staggered, so that the upper protrusion 5 can be inserted into the lower protrusion 6, so that the upper protrusion 5 and the lower protrusion 6 can be interlocked with each other to achieve an intersecting arrangement. The upper protrusion 5 and the lower protrusion 6 are provided with a rotation hole 8 that runs through the body. When in use, a rotation shaft 9 is inserted into the rotation hole 8, so that the upper electrode holder 1 and the lower electrode holder 2 can rotate around the rotation shaft 9.

[0024] Both ends of the upper electrode holder 1 and the lower electrode holder 2 are provided with electrode insertion holes and lifting blocks 10. The electrode insertion holes are used to insert electrodes. One side of the electrode insertion holes is also provided with locking holes 13. The locking holes 13 are connected to the electrode insertion holes, and a locking rod is inserted into the locking holes 13. The locking rod is used to fix the electrode. Due to the different degrees of insertion of the locking rod, electrodes of different sizes can be fixed. At the same time, an electromagnetic cylinder structure is provided on one of the lifting blocks 10. In other structures, a cylinder or manual pushing of a lifting block 10 can be used to move it away from or close to another lifting block 10. The telescopic rod of the electromagnetic cylinder structure is connected to the other lifting block 10. In this way, when the electromagnetic cylinder is in action, the upper electrode holder 1 or the lower electrode holder 2 can be pushed to rotate around the rotating axis 9, so that the two lifting blocks 10 are away from each other, so that the upper electrode 3 and the lower electrode 4 at the other end will approach each other, thereby realizing welding. Since the upper electrode holder 1 and the lower electrode holder 2 are both integral structures, under the action of the electromagnetic cylinder, the upper and lower electrodes 4 are approached to each other for welding, and the approaching process is more stable. The upper electrode holder 1 and the lower electrode holder 2 exert force on each other, giving greater pressure to the product to be welded.

[0025] A double cooling water channel is arranged in the lower electrode holder 2 and the upper electrode holder 1. A cooling water hole 11 is arranged at the end of the cooling water channel. The cooling water hole 11 is arranged on the surface of the lower electrode holder 2 and the upper electrode holder 1. It is a double cooling water channel and a double water circulation. During the welding process, high temperature is generated. With the water circulation, the electrode temperature can be cooled, the service life of the electrode is increased, and the welding quality is stabilized.

[0026] A plurality of fixing holes 12 are provided on the sides of the lower electrode holder 2 and the upper electrode holder 1. When in use, the upper electrode holder 1 or the lower electrode holder 2 is positioned according to the specific structure, and then the fixing holes 12 on the selected fixed electrode holder are inserted with screws to fix it on the platform, and then the electric cylinder structure is installed on the fixed electrode holder, and then the electrode is assembled and locked, and then the product is placed between the upper electrode 3 and the lower electrode 4, and the electric cylinder structure is started to bring the upper electrode 3 and the lower electrode 4 close to each other, and then the product is welded. During the process of approaching, due to the fixed structural relationship between the upper electrode holder 1 and the lower electrode holder 2, the electrode moves forward stably, and a larger pressure can be transmitted through the electric cylinder structure, making the welding more stable. At the same time, during use, cooling water is provided in the cooling water channel to prevent the electrode temperature from being too high.

[0027] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
