[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] See also Figure 1-Figure 9A copper-clad sheet welding tool comprises a welding tabletop 1 and four table legs 2 installed on the bottom surface of the welding tabletop 1, a plurality of adjustment boxes 4 are connected to both sides of the welding tabletop 1, the interiors of the plurality of adjustment boxes 4 are connected to adjustment components, the upper ends of the plurality of adjustment components are connected to connection boxes 3, the interiors of the plurality of connection boxes 3 are connected to limit components and a movable plate 7, and the limit components and the movable plate 7 in the same connection box 3 are abutted against each other, the ends of the plurality of movable plates 7 close to the welding tabletop 1 are connected to support columns 9, the sides of the plurality of support columns 9 away from the movable plate 7 are connected to lifting components, the lower ends of the plurality of lifting components are connected to support blocks 17, and the interiors of the plurality of support blocks 17 are connected to extrusion components.

[0030] like Figures 1 to 9 As shown, when the copper-clad sheet welding tool in the present invention is used, first the copper-clad sheet to be welded is brought to the upper surface of the welding table 1, and then the position, height, angle, etc. of several extrusion components are adjusted according to the shape of the copper-clad sheet. First, the adjustment component can be lifted upward, and as the adjustment component rises, the limit component, the connection box 3 and the movable plate 7 will rise together, and then the movable plate 7 is pulled and limited by the limit component. At this time, the height and length of the extrusion component relative to the welding table 1 have been adjusted, and then the inclination angle of the extrusion component relative to the welding table 1 is rotated by the lifting component. When the angle is adjusted, the copper-clad sheet can be extruded and supported by the extrusion component, which is convenient, fast and easy to operate.

[0031] As a preferred embodiment of the present invention, the adjustment assembly includes a clamping rod 6, an adjusting knob 5 and a plurality of fan-shaped blocks 21, the bottom surfaces of the plurality of fan-shaped blocks 21 are fixedly connected to one side of the adjusting knob 5, a trapezoidal hole 30 is penetrated through the inner wall of the adjusting box 4, one end of the plurality of fan-shaped blocks 21 away from the adjusting knob 5 penetrates the trapezoidal hole 30 and is threadedly connected to the inner wall of the trapezoidal hole 30, the upper end of the clamping rod 6 penetrates the adjusting knob 5, the trapezoidal hole 30 and the plurality of fan-shaped blocks 21 and is fixedly connected to the bottom surface of the connecting box 3.

[0032] More specifically, when it is necessary to raise the height of the extrusion assembly relative to the welding table 1, first rotate the adjusting knob 5. After the adjusting knob 5 is rotated, it will drive the fan-shaped block 21 connected above to be rotated out along the trapezoidal hole 30, thereby causing a certain amount of looseness. While loosening, push the clamping rod 6 upward. When it is pushed to a suitable height, rotate the adjusting knob 5 in the opposite direction again, screw the fan-shaped block 21 back into the trapezoidal hole 30, and then squeeze the clamping rod 6 in the middle through the clamping force of the fan-shaped block 21 and the trapezoidal hole 30, thereby completing the limit and preventing it from slipping.

[0033] As a preferred embodiment of the present invention, the limit assembly includes a limit head 26, a pull rod 27, a limit spring 28 and a pull plate 16. A connected spring groove 22 and a movable groove 23 are provided inside the connecting box 3. One end of the movable plate 7 away from the support column 9 passes through the movable groove 23 and is slidably connected to the inner wall of the movable groove 23. One end of the limit spring 28 is fixedly connected to the top surface of the spring groove 22, and the other end of the limit spring 28 is fixedly connected to the limit head 26. The lower end of the limit head 26 is abutted against the movable plate 7, and the upper surface of the limit head 26 is fixedly connected to the pull rod 27. The other end of the pull rod 27 passes through the limit spring 28 and the spring groove 22 and is fixedly connected to the pull plate 16. The bottom surface of the pull plate 16 is abutted against the upper surface of the outer wall of the connecting box 3.

[0034] To be more specific, when the clamp rod 6 rises, it will push the connecting box 3 connected to it upward. At this time, the movable plate 7 and the limit assembly inside the connecting box 3 move upward at the same time. When the extension length of the movable plate 7 needs to be adjusted, the pull plate 16 is first pulled out. When the pull plate 16 is pulled out, the pull rod 27 and the limit head 26 connected below will be pulled upward together. At the same time, the limit spring 28 is compressed, and a gap appears between the limit head 26 and the movable plate 7 after it moves upward, so that the limit on the movable plate 7 can be cancelled. At this time, the movable plate 7 can be slid according to demand. When the distance is appropriate, the pull plate 16 is opened, the limit spring 28 recovers its deformation and the limit head 26 is again offset against the movable plate 7, so that the limit can continue, which is more convenient and saves trouble.

[0035] As a preferred solution of the present invention, the lifting assembly includes a moving block 25, a screw rod 24, a rotating plate 11 and a screw 12. A movable groove 18 is opened on the side of the support column 9 away from the moving plate 7. The moving block 25 is located inside the movable groove 18 and is slidably connected to the movable groove 18. The side of the moving block 25 away from the movable groove 18 is fixedly connected to the screw rod 24. The other end of the screw rod 24 passes through the rotating plate 11 and is threadedly connected to the screw 12. The end of the rotating plate 11 away from the screw rod 24 is rotatably connected to the support block 17 through a rotating shaft.

[0036] More specifically, when the height and length have been adjusted, if the clamping angle of the extrusion assembly is still not suitable for the copper-clad sheet, the screw 12 can be rotated. After the screw 12 is rotated, it will be screwed outward along the thread of the screw rod 24 for a distance. The screw 12 after being screwed out cannot form a clamping force between the rotating plate 11 and the support column 9. At this time, the rotating plate 11 can be rotated to rotate the extrusion assembly to a suitable position and then stop. Then, the screw 12 can be rotated again. The screw 12 rotates along the screw rod 24 and squeezes the rotating plate 11 and the support column 9 again, thereby preventing the rotating plate 11 from rotating back by itself; and through the provided movable groove 18, the rotating plate 11 can be moved up and down after loosening the screw 12, which can meet the rotation support in more cases and is more convenient and quick; and it should be noted here that the support block 17 and the rotating plate 11 are connected by a damping shaft.

[0037] As a preferred embodiment of the present invention, the extrusion assembly includes a turning handle 13, a threaded rod 14 and a pressure plate 19. The threaded rod 14 passes through the support block 17 and is threadedly connected to the inner wall of the support block 17. The turning handle 13 and the pressure plate 19 are fixedly connected to the two ends of the threaded rod 14 respectively.

[0038] More specifically, after the angle of the pressure plate 19 has been adjusted by the turn plate 11, the handle 13 is turned. After the handle 13 is turned, the threaded rod 14 will rotate downward along the support block 17, so that the pressure plate 19 can be gradually pressed against the surface of the copper-clad sheet material that needs to be limited, and the copper-clad sheet material can be gradually squeezed to complete the limitation.

[0039] As a preferred solution of the present invention, a plurality of limiting holes 8 are formed through the upper surface of the movable plate 7 , and one end of the limiting head 26 away from the limiting spring 28 is slidably connected to the inner wall of the limiting hole 8 .

[0040] More specifically, by inserting the limit head 26 into the limit hole 8, the connection between the limit head 26 and the movable plate 7 can be made more stable; and it should be particularly noted here that the limit head 26 and the limit hole 8 have the same diameter, and the limit head 26 completely penetrates the limit hole 8, so that the two will not fall off by themselves without pulling the pull plate 16.

[0041] As a preferred solution of the present invention, a pull rope 29 is fixedly connected to a side of the pull plate 16 away from the connection box 3 .

[0042] More specifically, the pull rope 29 can be provided to make it easier to pull out the pull plate 16 .

[0043] As a preferred solution of the present invention, a stopper 15 is fixedly connected to one end of the movable plate 7 away from the supporting column 9 , and the height of the stopper 15 is greater than the height of the movable groove 23 .

[0044] More specifically, the stopper 15 can prevent the moving plate 7 from falling from the inside of the connection box 3 .

[0045] As a preferred solution of the present invention, slide grooves 31 are provided on both sides of the welding desktop 1, and a plurality of adjustment boxes 4 are fixedly connected with sliders 20 on one side close to the welding desktop 1, and a plurality of sliders 20 are slidably connected to the two slide grooves 31 respectively.

[0046] More specifically, by setting the slide groove 31 and the slider 20, firstly, the adjustment box 4 can be moved to change the position of the movable plate 7, the extrusion assembly, etc., to match the copper-clad board clamping in more situations, and secondly, it can also prevent the adjustment box 4 and the like from falling from the welding table 1.

[0047] As a preferred solution of the present invention, a plurality of insertion holes 10 are formed through one side of the support column 9 .

[0048] More specifically, by providing the insertion hole 10, when the copper-clad board is clamped, a support rod or other supporting object can be inserted into the insertion hole 10 for auxiliary support, so that the copper-clad board is more stable when clamped and is not easy to tilt.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
