[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0019] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0020] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a multifunctional welding wire welding device of the utility model comprises a C-shaped shell 1 and a plurality of clamping blocks 3, wherein strip openings 9 are provided on both sides of the C-shaped shell 1, and notches 2 communicating with the outside are provided in the middle of the strip openings 9, and the clamping blocks 3 are arranged in the strip openings 9, and arc-shaped avoidance grooves 4 are provided at the clamping blocks 3 opposite to the notches 2, and a U-shaped shell 5 is provided on the outside of the C-shaped shell 1 for pushing the clamping blocks 3 inward.

[0022] In this embodiment, a fixing portion 10 is protruded on the bottom surface of the C-shaped shell 1, and a bearing is embedded on the bottom surface of the fixing portion 10. A screw hole is provided on the bottom surface of the U-shaped shell 5 opposite to the inner ring of the bearing, and a screw rod 11 is threadedly connected in the screw hole. The upper end of the screw rod 11 is installed in the inner ring of the bearing, and a hand wheel 6 is installed at the lower end.

[0023] In this embodiment, arc-shaped clamping surfaces 12 are provided on the opposite surfaces of the clamping block 3, and the clamping surfaces 12 extend to the interior of the C-shaped shell 1. A guide portion 13 is obliquely provided on the opposite surface of the clamping block 3, and the top surface of the U-shaped shell 5 is arranged to abut against the guide portion 13.

[0024] In this embodiment, the inner side of the U-shaped shell 5 is arranged in contact with the outer side of the C-shaped shell 1, so that the U-shaped plate can only move upward along the outer side of the C-shaped shell, avoiding the rotation of the U-shaped shell and increasing the stability of the U-shaped shell when moving.

[0025] In this embodiment, a plurality of support columns 7 are installed on the bottom surface of the C-shaped shell 1, and a base plate 8 is installed at the lower end of the support column 7. The device can be placed on any plane through the base plate, and fixing holes can also be provided on the base plate, and screws can pass through the fixing holes to fix the base plate at any position.

[0026] In this embodiment, the C-shaped shell 1, the U-shaped shell 5 and the clamping block 3 are all made of metal materials, which increases the firmness and service life.

[0027] In this embodiment, the length and thickness of the clamping block 3 match the length and height of the strip opening 9, so that the clamping block can only move along the strip opening, avoiding shaking and swinging and increasing stability.

[0028] When welding, the metal wire can be placed in the C-shaped shell, and the screw can be rotated by the hand wheel. The rotation of the screw drives the U-shaped shell, so that the U-shaped shell moves upward along the outer surface of the C-shaped shell. The upwardly moving U-shaped shell can squeeze the guide part, so that the clamping block moves inward along the strip-shaped opening, thereby clamping and fixing the metal wire. Since the C-shaped shell is provided with a notch, and the avoidance groove is provided on the clamping block, the joint of the metal wire has a larger welding gap, so that the welding liquid is prevented from contacting the clamping block during welding. After the metal wire is welded and fixed at one point, the hand wheel can be rotated in the opposite direction to move the U-shaped plate downward. After the inward thrust of the U-shaped plate is lost, the metal wire will lose the inward clamping force, so that the metal wire can rotate. The joint of the metal wire can be welded in a circle by rotating, thereby increasing the strength of the welding.

[0029] Among them, after the U-shaped shell moves downward, there is no obstruction on the outside of the clamping block, so that the clamping block can be directly taken out, which facilitates the replacement of the clamping block and enables the selection of clamping blocks with different clamping surfaces, so that metal wires of different diameters can be clamped and fixed, increasing adaptability.

[0030] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
