[0035] See also Figure 1-3 A portable welding fixture comprises a base 1, the upper surface of the base 1 is slidably connected to a sliding seat 6, the upper surface of the sliding seat 6 is movably connected to a fixture plate 3 through a bearing, and the side surface of the fixture plate 3 is fixedly connected to an extrusion seat 5;

[0036] The rear surface of the base 1 is movably connected to a carrying box 7 through a bearing, the interior of the carrying box 7 is fixedly connected to a fixing seat 10, and the fixing seat 10 is concavely arranged, an air bag 32 is arranged on the inner wall of the fixing seat 10, a one-way tube 25 is arranged on the side surface of the air bag 32, a metal sheet 33 is arranged on the front surface of the air bag 32, a corner block 31 is fixedly connected to the front surface of the metal sheet 33, and a rubber strip 14 is arranged on the front surface of the corner block 31.

[0037] By utilizing the sliding of the sliding seat 6 and the base 1, the sliding seat 6 can be pushed to one side. When the sliding seat 6 moves, the clamp plate 3 can be driven to move. When the workpiece is welded, the workpiece can be placed between the clamp plates 3 for clamping and fixing. Since the side surface of the clamp plate 3 is provided with an extrusion seat 5, the clamp plate 3 can be well fitted with the workpiece, which is convenient for welding the workpiece. Therefore, the distance between the clamp seats can be adjusted. Since the connection between the sliding seat 6 and the clamp plate 3 is connected by a bearing, the clamp plate 3 can be moved with the upper surface of the sliding seat 6 as the center of the circle, and the clamp plate 3 can be placed parallel to the top of the base 1. By utilizing the movement of the carrying box 7 and the base 1, it can be moved with the rear surface of the base 1 as the center of the circle and matched with the base 1. When When the carrying box 7 is combined with the base 1, the clamp plate 3 can be embedded in the interior of the fixed seat 10, so that the front and rear surfaces of the clamp plate 3 are both in contact with the surface of the airbag 32 to squeeze the airbag 32. The heights of the squeezed surface and the non-extruded surface of the airbag 32 are different, so that the airbag 32 can drive the metal plate to move and fit with the surface of the clamp plate 3. When the clamp plate 3 squeezes the airbag 32, the clamp plate 3 can push the rubber strip 14 upward, and the connection between the rubber strip 14 and the corner block 31 can be bent and fit with the surface of the airbag 32, so that the rubber strip 14 can reduce the gap between the airbag 32 and the clamp plate 3, and the metal plate can fit with the upper surface of the clamp plate 3 to block it, so that the carrying box 7 can squeeze and fix the clamp plate 3, thereby facilitating the carrying and use of the clamp.

[0038] See also Figure 1-Figure 6The side surface of the sliding seat 6 is fixedly connected to the first support plate 11, the upper surface of the first support plate 11 is fixedly connected to the first mounting plate 21, the rear surface of the first mounting plate 21 is movably connected to the first shaft rod 20 through a bearing, the side surface of the first shaft rod 20 is sleeved with the telescopic rod 12, and the front surface of the telescopic rod 12 is threadedly connected with a bolt 19.

[0039] Since the first shaft 20 is connected to the bottom end of the telescopic rod 12, the bottom end of the telescopic rod 12 can move on the surface of the first support plate 11. Since the telescopic rod 12 is composed of a thick rod and a thin rod connected in a sleeve, the length of the telescopic rod 12 can be adjusted. When the length of the telescopic rod 12 is adjusted, the bolt 19 can be screwed to fix the telescopic rod 12 with the adjusted length, so that it can support the clamp plate 3. Since the top and bottom ends of the telescopic rod 12 are installed at an angle, the inclination angle of the clamp seat can be adjusted, which is convenient for folding, storing and carrying the clamp plate 3.

[0040] See also Figure 6 The end of the telescopic rod 12 away from the first shaft 20 is sleeved with the second shaft 18, and the two ends of the second shaft 18 are movably connected to the second mounting plate 17 through bearings. The upper surface of the second mounting plate 17 is fixedly connected to the second support plate 4, and the second support plate 4 is fixedly connected to the side surface of the clamp plate 3.

[0041] The top end of the telescopic rod 12 is connected to the side surface of the clamp plate 3 through the second shaft rod 18. Since the length of the second mounting plate 17 is shorter than the length of the first mounting plate 21, the telescopic rod 12 can be installed at an angle, and the top and bottom ends of the telescopic rod 12 are respectively movable by the first shaft rod 20 and the second shaft rod 18, so that when the clamp plate 3 is vertically unfolded for use, the telescopic rod 12 can conveniently support the clamp plate 3, thereby improving the stability of the clamp plate 3 when used vertically.

[0042] See also Figure 4-5 The front surface of the first support plate 11 is fixedly connected to the fixed plate 13, the upper surface of the fixed plate 13 is fixedly connected to the open plate 22, the inside of the open plate 22 is fixedly connected to the slide plate 27, the front surface of the slide plate 27 is slidably connected to the movable rod 28, the side surface of the movable rod 28 is sleeved with a movable sleeve 29, and the side surface of the movable sleeve 29 is fixedly connected to the pull rod 24.

[0043] Since the side surface of the open plate 22 is open, the bottom end of the pull rod 24 can extend into the interior of the open plate 22. The opening diameter of the movable sleeve 29 is larger than the movable rod 28. When the insertion rod 26 drives the pull rod 24 to move up and down, the pull rod 24 can drive the movable sleeve 29 to move in a semicircle on the surface of the movable rod 28, so that the movable sleeve 29 can be easily attracted to the magnetic block 30 to fix the insertion rod 26.

[0044] See also Figure 5A magnetic block 30 is disposed inside the fixed plate 13 , and the magnetic block 30 is attracted to the movable sleeve 29 .

[0045] When the movable rod 28 drives the movable sleeve 29 to slide on the surface of the slide plate 27, the movable sleeve 29 can move to the front of the magnetic block 30. Since the thickness of the lower surface of the movable sleeve 29 is greater than the upper surface of the movable sleeve 29, the pull rod 24 can be used to drive the movable sleeve 29 to rotate in a semicircle on the surface of the movable rod 28, so that the thicker surface of the movable sleeve 29 can fit with the magnetic block 30 for magnetic attraction to fix the movable sleeve 29, the pull rod 24 and the insertion rod 26, so that the fixture plate 3 is more convenient to fix, and at the same time, it can replace the bolts to fix the fixture plate 3, thereby improving the fixing effect of the fixture plate 3.

[0046] See also Figure 4 The inside of the fixed plate 13 is slidably connected with an insertion rod 26, and the insertion rod 26 is engaged with the upper surface of the base 1. Both sides of the insertion rod 26 are fixedly connected with connecting plates 23, and the rear surface of the connecting plate 23 is movably connected to the top of the pull rod 24 through a bearing.

[0047] When the distance between the clamp plates 3 is adjusted, the insertion rod 26 can be pushed downward to pass through the fixed plate 13 and engage into the interior of the base 1 to fix the sliding seat 6. When the insertion rod 26 moves, the insertion rod 26 can drive the pull rod 24 to move. Since the top end of the pull rod 24 is movably connected to the two sides of the insertion rod 26, when the insertion rod 26 moves, the top end of the pull rod 24 can move on both sides of the insertion rod 26 with the center of the connecting plate 23 as the point, so that the pull rod 24 can adjust the inclination angle of the pull rod 24 according to the moving height of the insertion rod 26.

[0048] See also Figure 1-2 A first fastening plate 2 is fixedly connected to the front surface of the base 1, a second fastening plate 8 is fixedly connected to the rear surface of the carrying box 7, a threaded rod 9 is threadedly connected to the inner thread of the second fastening plate 8, and the threaded rod 9 is threadedly connected to the first fastening plate 2.

[0049] When the carrying box 7 is combined with the base 1, the first fastening plate 2 and the second fastening plate 8 can be fitted together, and the threaded rod 9 is screwed so that it can penetrate the second fastening plate 8 and extend into the interior of the first fastening plate 2 to fix the first fastening plate 2, so that the carrying box 7 can easily store the clamp.

[0050] See also Figure 1 A ball 15 is movably connected to the front surface of the base 1 , and a handle 16 is fixedly connected to the front surface of the ball 15 .

[0051] Since the circular hole on the front surface of the base 1 has the same cross-section as the ball 15, the ball 15 can be fitted into and moved in the circular hole, and the handle 16 can be placed parallel to or vertically to fit the surface of the base 1 by utilizing the movement of the ball 15. When the carrying box 7 is combined and fixed with the base 1, the handle 16 can be used to carry the device by hand.

[0052] When in use, the top and bottom ends of the telescopic rod 12 are movable so that the clamp plate 3 can be clamped at an angle. When the clamp plate 3 is continuously vertical, the length of the telescopic rod 12 can be lengthened, and the bolt 19 can be screwed to fix the telescopic rod 12, so that the clamp plate 3 can be used vertically, and the clamp plate 3 is moved to one side so that the sliding seat 6 can drive the clamp plate 3 to move on the surface of the base 1, so that the distance between the clamp plates 3 can be adjusted. When the distance between the clamp plates 3 is adjusted, the insertion rod 26 can be pushed downward so that the pull rod 24 can drive the movable rod 28 and the movable sleeve 29 to move downward, and the insertion rod 26 can penetrate the fixed plate 13 and be embedded in the interior of the base 1 to fix the sliding seat 6. When the pull rod 24 is moving, the movable sleeve 29 can move on the surface of the movable rod 28, so that the movable sleeve 29 can be attracted to the magnetic block 30 to adjust the movable sleeve 29, the pull rod 24 and the insertion rod. The rod 26 is fixed, and the clamp plate 3 can clamp and fix the workpiece to be welded. When the clamp is used, the bolt 19 is turned in the opposite direction so that the clamp plate 3 can be placed parallel to the surface of the base 1, and the movable carrying box 7 can be combined with the base 1, and the clamp plate 3 can be embedded in the interior of the fixed seat 10, so that the front and rear surfaces of the clamp plate 3 are both in contact with the surface of the airbag 32 to squeeze the airbag 32, and the airbag 32 can drive the metal plate to move and fit the surface of the clamp plate 3, and the connection between the rubber strip 14 and the corner block 31 can be bent and fit the surface of the airbag 32, so that the rubber strip 14 can reduce the gap between the airbag 32 and the clamp plate 3, and the threaded rod 9 is turned so that it can pass through the second fastening plate 8 and extend into the interior of the first fastening plate 2 to fix the first fastening plate 2.
