[0024] The technical solution of this utility model will be further described below with reference to specific embodiments:

[0025] An adjustable gas cutting backing, such as Figure 1 and Figure 2 As shown, it includes a clamping part 1 for holding a gas cutting torch and a support rod for supporting the height of the clamping part; the clamping part 1 is a split clamping part, and the split clamping parts 1 are connected and engaged by bolts. The clamping part 1 is provided with a clamping groove for holding the gas cutting torch at the split engagement surface. Taking acetylene cutting as an example, the torch has an acetylene gun barrel 2 and an oxygen tube 3, and the clamping part is provided with clamping grooves for holding the acetylene gun barrel 2 and the oxygen tube 3 respectively.

[0026] A scale 4 is provided on both sides of the split clamping part 1. The scale 4 has scales distributed along an arc, that is, the scales on the scale can be distributed in a circle or in a partial arc. A connecting shaft 5 is provided at the center of the arc where the scale is located on the scale 4. The support rod is rotatably connected to the connecting shaft 5. The connecting shaft 5 is also provided with a locking nut 6 for locking the rotation angle of the support rod relative to the connecting shaft 5. The locking nut 6 is threadedly connected to the connecting shaft 5.

[0027] To provide support during cutting at different heights, the support rod includes a first support rod 7 and a second support rod 8. One end of the first support rod 7 is rotatably connected to the connecting shaft 5, and the other end of the first support rod 7 is provided with a mounting hole for installing and adjusting the second support rod 8. One end of the second support rod 8 is movably inserted into the mounting hole. The length of the support rod is adjusted by adjusting the depth of the second support rod 8 inserted into the mounting hole.

[0028] In one embodiment, the second support rod 8 and the first support rod 7 are connected by a threaded fit between their mounting holes, and the overall length of the support rod can be adjusted by rotating the second support rod 8 relative to the first support rod 7.

[0029] In another embodiment, the outer surface of the second support rod 8 is smooth, the inner surface of the mounting hole is smooth, and a bolt is provided on the outer side of the mounting hole to abut against the outer surface of the second support rod 8 to limit the length of the support rod.

[0030] When using the cutting torch, adjust the length of the support rod and the angle of the support rod relative to the connecting shaft, then move the torch to cut. During the movement, the lower end of the support rod, i.e., the bottom of the second support rod 8, rests against the horizontal bulkhead 13, thereby cutting the steel plate of the longitudinal bulkhead 12. (Refer to...) Figure 4 .

[0031] Preferably, to increase the stability of the support rod, such as Figure 3As shown, a support base 9 is also provided at the bottom of the support rod. The support base 9 has an upward-facing insertion hole corresponding to the support rod. The support rod can be detachably inserted into the insertion hole of the support base. Experienced construction workers can choose not to use the support base 9, while less experienced construction workers can choose to insert the support rod into the insertion hole of the support base during cutting to increase the stability during cutting and translation. The support base can be a flat structure such as a steel plate or a wooden board.

[0032] To facilitate movement, rollers can be installed at the bottom of the support base. The rollers can be rollers with axles or ball bearings.

[0033] Preferably, the support base 9 is also provided with a through hole that runs horizontally through the support base, and the through hole is perpendicular to the direction of the insertion hole; a length adjusting rod 10 is inserted into the through hole, and a backing plate 11 is provided at the end of the length adjusting rod 10; a locking bolt is provided on the side of the support base 9 corresponding to the through hole, and one end of the locking bolt is inserted into the through hole from the outside of the support base to abut against the outer wall of the length adjusting rod 10 to adjust the distance between the backing plate 11 and the support base 10. After the adjustment is completed, the position of the length adjusting rod is locked by the locking bolt.

[0034] Preferably, rollers can be provided on the side of the backing plate that is against the steel plate to be cut in order to facilitate the movement of the backing plate. The rollers can be rollers with axles or ball bearings.

[0035] When using, such as Figure 4 As shown, taking the cutting of the steel plate at the position of the longitudinal bulkhead 11 as an example, there is a horizontal bulkhead 13 at the root of the longitudinal bulkhead 12. The cutting line 14 is drawn on the steel plate of the longitudinal bulkhead 11. The angle and height of the cutting torch are adjusted. After the adjustment is completed, the lower end of the support rod is inserted into the insertion hole of the support base 9. The support base 9 is placed on the horizontal bulkhead 13. The length of the length adjustment rod is adjusted so that the backing plate 11 abuts against the steel plate of the longitudinal bulkhead 14, ensuring that the cutting end of the cutting torch faces and is close to the cutting line. After ignition, the cutting torch and backing plate are manually moved so that the cutting end of the cutting torch cuts along the cutting line 14.

[0036] It should be noted that when the cutting line is close to the root of the longitudinal bulkhead, the cutting end is relatively close to the abutment plate. In this case, the abutment plate should not be used, or the abutment plate should be offset from the cutting end of the cutting torch. Figure 5 As shown, a backing plate 11 is provided at the end of each of the two length adjustment rods 10, and the cutting end of the cutting torch is positioned between the two backing plates 11 to prevent the flame at the cutting end from burning the backing plate 11.

[0037] This embodiment is merely a further explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art can make non-inventive modifications to this embodiment as needed, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present invention.
