[0044] Example

[0045] This embodiment provides an electrode fixing device, such as Figure 1 As shown, including:

[0046] The fixing seat 31 includes a cylindrical body 312 and a front stopper 313. An accommodating portion 311 is provided between the cylindrical body 312 and the front stopper 313. A through slot 314 with a side opening is provided on the front stopper 313. The cylindrical body 312 is used to connect with the rotation driving device.

[0047] The electrode connector 91 is used to be installed at the end of the electrode, and includes an electrode connector body 911. The electrode connector body 911 is also provided with an electrode fixing groove 913 for the electrode 9 to extend into and fix the electrode 9; the electrode connector body 911 can be inserted into the accommodating portion 311 from the side and the front end of the electrode connector body 911 can be inserted into the through groove 314.

[0048] In the electrode fixing device of this embodiment, the fixing seat 31 is connected to the rotation driving device, and the electrode connector 91 is installed at the end of the electrode. The operator can use his hands to take the electrode connector 91, and insert the electrode connector body 911 of the electrode connector 91 into the accommodating portion 311 of the fixing seat 31 from the side. The front end of the electrode connector body 911 can be inserted into the through groove 314, so that the electrode connector 91 connects the electrode 9 to the rotation driving device. The rotation driving device can drive the fixing seat 31 and the electrode connector 91 to rotate together with the electrode 9. After use, the operator can also easily remove the electrode connector 91 from the fixing seat 31. The whole process is simple to operate and easy to use.

[0049] Furthermore, if Figure 2 and Figure 3 As shown, the through slot 314 has an arc-shaped groove in the middle of the top, and the electrode connector body 911 has an arc-shaped protrusion that matches the arc-shaped groove on the through slot 314. The arc-shaped groove can facilitate the fixing seat 31 to clamp the electrode connector 91.

[0050] Furthermore, the electrode connector body 911 also has a polygonal outer wall to cooperate with the receiving portion 311, such as Figure 3 The structure shown is a hexagonal structure, and the receiving portion 311 is also provided with steps matching the hexagonal structure.

[0051] Furthermore, there is a gap between the front end of the electrode connector body 911 and the inner wall of the front stopper 313. The gap allows the electrode connector 91 to move relative to the fixing seat 31 to a certain extent, which is convenient for operation. Figure 4 Marked as L1.

[0052] Furthermore, if Figure 5 As shown, the electrode fixing groove 913 is a semi-cylindrical groove with an opening facing downward, and a plurality of fixing protrusions 9131 are formed inside to clamp the electrode 9.

[0053] Furthermore, the rear end of the electrode connector body 911 has a through hole, the electrode fixing groove 913 is connected to the through hole at the rear end of the electrode connector body 911, and a movable block 912 is inserted into the through hole to fix the electrode 9. When the movable block 912 is pulled out, the guide steel wire at the tail of the electrode can be inserted into the through hole at the rear end of the electrode connector body 911. When the movable block 912 is inserted into the through hole of the electrode connector body 911 to complete the tight fit, the steel wire of the electrode can be fixed, and then the electrode is fixed.

[0054] Furthermore, if Figure 6 As shown, the movable block 912 includes: a cylindrical portion 9121 extending into the rear end through hole of the electrode connector body 911, a protrusion 9122 located on one side of the cylindrical portion, and a head 9123 located outside the through hole. Accordingly, the shape of the through hole is also consistent with the cylindrical portion 9121 and the protrusion 9122, which can prevent the movable block 912 from rotating.

[0055] like Figure 7 As shown, the end of the fixing seat 31 has a mounting hole to be connected to the rotating shaft of the rotation driving device 2. Finally, the rotation driving device 2 drives the electrode fixing device to rotate, thereby causing the electrode 9 to rotate.

[0056] Based on the above ideal embodiments of this application, the relevant staff can make various changes and modifications without departing from the technical concept of this application through the above description. The technical scope of this application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
