One end of the limiting bolt 9 is fixedly installed in the middle of the inner side of the angle steel 5, and the other end of the limiting bolt 9 passes through the limiting groove 2 and is inserted into the angle ring 1. The limiting bolt 9 is fixed to the angle ring 1 by the limiting nut 10. The flat iron 6 is fixedly installed below the contact edge between the angle steel 5 and the angle ring 1. The two adjusting nuts 7 are fixedly installed on the flat iron 6. The clamping threaded rod 8 passes through the two adjusting nuts 7 and is connected to the adjusting nuts 7 by thread engagement.

[0028] In this embodiment, a fixing strip 11 is provided on the flat iron 6. The fixing strip 11 is located between the flat iron 6 and the adjusting nut 7 and is fixedly connected to the flat iron 6 on one side and to the adjusting nut 7 on the other side. The fixing strip 11 enhances the strength of the connection between the adjusting nut 7 and the flat iron 6.

[0032] In the implementation scheme of this embodiment, the manufacturing method of this utility model consists of the following steps;

[0033] 1. Fabrication of Angle Ring 1;

[0034] A DN80 steel pipe is used, and a section of a ring with the same diameter and height is cut. A groove with a circumference of 3 / 4 of the steel pipe is cut in the middle of the ring as a limiting groove 2. The groove is 1cm wide and the angle range of the groove is 0°-270°.

[0035] 2. Fabrication and installation of the fastening part 3;

[0036] An L40*40 angle steel 5 is welded onto the angle ring 1 to form a single unit. A 15cm long and 3cm wide flat iron 6 is welded below the contact edge between the angle steel 5 and the angle ring 1. A 1.5*1.5cm fixing strip 11 is welded to the upper part of the flat iron 6. Two φ10 adjusting nuts 7 are welded to both ends of the fixing strip 11, reinforcing the connection between the adjusting nuts 7 and the flat iron 6. An M8*10 threaded clamping rod 8 passes through the two adjusting nuts 7 and is threaded to them. A 5cm long DN10 round steel bar is welded vertically to the outer end of the threaded clamping rod 8 to serve as a handle 12 for clamping the threaded rod 8.

[0037] 3. Adjusting the fabrication and installation of fastening part 4;

[0038] An M8*10 limiting bolt 9 is welded to the middle of the L40*40 angle steel 5. The limiting bolt 9 passes through the limiting groove 2 on the angle ring 1 and is fixed by the limiting nut 10. This limiting bolt 9 allows the adjusting fastener 4 to move along the limiting groove 2, controlling the angle. A flat iron 6, 15cm long and 3cm wide, is welded below the edge of the angle steel 5. A 1.5*1.5 fixing strip 11 is welded to the upper part of the flat iron 6, and two φ10 adjusting nuts 7 are welded to both ends of the fixing strip 11. An M8*10 clamping threaded rod 8 passes through the two adjusting nuts 7 and is threaded to them. A 5cm long round steel DN10 is welded vertically to the outer end of the clamping threaded rod 8 to serve as a handle 12 for clamping the threaded rod 8. The handle 12 allows the user to more easily adjust the angle between the fixing fastener 3 and the adjusting fastener 4.

[0039] Furthermore, the operation mode of the device in this embodiment is as follows:

[0040] Using the angle ring 1 as a connection point, a fixed fastening part 3 and an adjusting fastening part 4 are respectively provided on both sides to clamp the component. The fixed fastening part 3 is welded to the angle ring 1, and the adjusting fastening part 4 is connected to the angle ring 1 by a limit bolt 9 to adjust the angle, forming the overall operating system of the tool.

[0041] During component welding, one component is placed between the angle iron 5 of the fixed fastener 3 and the clamping threaded rod 8, and the other is placed between the angle iron 5 of the adjusting fastener 4 and the clamping threaded rod 8. The clamping threaded rods 8 on both the fixed fastener 3 and the adjusting fastener 4 are rotated. The movement of the clamping threaded rods 8 on the adjusting nut 7 clamps the component onto the fixed fastener 3 and the adjusting fastener 4. The rubber pad 13 on the clamping threaded rod 8 prevents damage to the component during clamping. After the component is fixed, the limiting nut 10 is loosened, and the clamping threaded rod 8 in the adjusting fastener 4 is moved to move the limiting bolt 9 on the limiting groove 2, thereby adjusting the welding angle. After the angle is fixed, the limiting nut 10 is tightened. Welding is then performed after the two components are tightly and neatly joined.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
