[0009] A vertically arranged mounting rod is provided on the top of the sliding block, and one end of the sleeve fixing rod is connected to the top of the mounting rod, so that the sleeve fixing rod is horizontally erected above the crank handle base and extends above the material to be cut.

[0010] A vertically arranged insertion rod is provided at the other end of the sleeve fixing rod, a socket cylinder is provided in the middle of the sleeve connecting rod, and the insertion rod is rotatably and liftably inserted into the socket cylinder and locked and fixed.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. Since the utility model is provided with a crank, a threaded rod, a sliding block and a gas cutting gun body, turning the crank by hand drives the threaded rod to rotate. By using the threaded transmission between the threaded rod and the sliding block, the gas cutting gun body and its cutting head can be moved to the cutting line of the material to be cut. At the same time, the threaded rod arranged parallel to the cutting line provides a movement guide for the cutting head, ensuring that the cutting head makes a stable linear movement along the cutting line, thereby ensuring the straightness of the cutting line and the flatness of the cutting surface, which is beneficial to improving the cutting efficiency and quality.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following further illustrates the utility model with reference to the drawings and specific embodiments.

[0023] Please refer to the attached Figure 1 and the attached Figure 2, A hand-cranked gas cutting tooling device, comprising a crank base 1, a crank handle 2, a threaded rod 3, a sliding block 4, an adjusting sleeve, and a gas cutting gun body 8; the crank base 1 is a trough structure with an open top, the threaded rod 3 is rotatably installed through the crank base 1, the axial direction of the threaded rod 3 is parallel to the cutting line of the material to be cut, and one end of the threaded rod 3 extends outside the crank base 1 and is coaxially fixed to one end of the crank handle 2; a threaded through hole matching the threaded rod 3 is formed in the sliding block 4, so that the sliding block 4 is threadedly sleeved on the threaded rod 3 and is slidably fitted in the crank base 1; one end of the adjusting sleeve is installed on the top of the sliding block 4, the other end of the adjusting sleeve extends to the side of the crank base 1, and the gas cutting gun body 8 is installed on the other end of the adjusting sleeve, so that the cutting head of the gas cutting gun body 8 is adjustably arranged above the material to be cut.

[0024] Preferably, the crank handle 2 can adopt a Z-shaped hand crank. One end of the crank handle 2 is fixedly connected to the threaded rod 3, and the other end of the crank handle 2 is for holding. By hand-cranking to control the rotation of the threaded rod 3, compared with the traditional hand-held gas cutting gun, the operation is more labor-saving and convenient.

[0025] Preferably, the width of the sliding block 4 is slightly smaller than the width of the trough of the crank base 1, so that the inner walls on both sides of the crank base 1 can limit the rotation of the sliding block 4, thereby converting the threaded rod 3 into a linear motion of the sliding block 4 along the axial direction of the threaded rod 3 by screw drive, and further realizing the synchronous linear motion of the sliding block 4 to drive the adjusting sleeve and the gas cutting gun body 8, so as to realize the position adjustment of the cutting head of the gas cutting gun body 8 and the moving cutting along the cutting line.

[0026] Please refer to the appendix Figure 1 , The adjusting sleeve includes a sleeve fixing rod 5, a sleeve connecting rod 6, and a gas cutting gun fixing rod 7; one end of the sleeve fixing rod 5 is connected to the sliding block 4, and the other end of the sleeve fixing rod 5 is connected to one end of the sleeve connecting rod 6; one end of the gas cutting gun fixing rod 7 is movably inserted into the sleeve connecting rod 6, and the gas cutting gun body 8 is locked to the other end of the gas cutting gun fixing rod 7.

[0027] The sleeve fixing rod 5 moves synchronously with the sliding block 4, and drives the sleeve connecting rod 6, the gas cutting gun fixing rod 7, and the gas cutting gun body 8 to move synchronously along the axial direction of the threaded rod 3. The gas cutting gun body 8 can be locked to the gas cutting gun fixing rod 7 by bolts.

[0028] Preferably, the length direction of the gas cutting gun fixing rod 7 is perpendicularly arranged to the length direction of the sleeve fixing rod 5, so that the gas cutting gun body 8 can have a two-dimensional adjustment function along the axial direction of the threaded rod 3 and perpendicular to the axial direction of the threaded rod 3, to meet the use requirements of the cutting head of the gas cutting gun body 8 at different cutting positions and the moving cutting requirements.

[0029] Preferably, the sleeve connecting rod 6 can be a cylindrical sleeve, and the gas cutting gun fixing rod 7 can be a cylindrical rod slightly smaller than the inner diameter of the cylindrical sleeve, so that the gas cutting gun fixing rod 7 can be inserted into the sleeve connecting rod 6 and move telescopically. After the movement is in place, the gas cutting gun fixing rod 7 can be locked and positioned by screwing in a bolt, which is used to adjust the position of the gas cutting gun body 8 in the direction perpendicular to the axial direction of the threaded rod 3.

[0030] Please refer to the appendix Figure 1 , the top of the sliding block 4 is provided with a vertically arranged mounting rod 9, and one end of the sleeve fixing rod 5 is connected to the top of the mounting rod 9, so that the sleeve fixing rod 5 is horizontally erected above the crank handle base 1 and extends above the material to be cut.

[0031] Preferably, the lower end of the mounting rod 9 and the sliding block 4 can be fixedly connected, or can be rotatably connected through a bearing seat. The upper end of the mounting rod 9 and the sleeve fixing rod 5 can be fixedly connected, or can be rotatably connected through a bearing seat. The height of the mounting rod 9 can be adaptively adjusted according to actual use requirements.

[0032] When the mounting rod 9 is fixedly connected, the sleeve fixing rod 5 can make a stable linear motion along the axial direction of the threaded rod 3; when the mounting rod 9 is rotatably connected, the sleeve fixing rod 5 can not only move along the axial direction of the threaded rod 3 but also has a horizontal rotation function, further expanding the position adjustment range of the cutting head of the gas cutting gun body 8, which is used to improve the accuracy of the cutting starting position.

[0033] Please refer to the appendix Figure 1 , the other end of the sleeve fixing rod 5 is provided with a vertically arranged insertion rod 10, and the middle part of the sleeve connecting rod 6 is provided with a socket cylinder 11. The insertion rod 10 can be rotatably and liftably inserted into the socket cylinder 11 and locked and fixed.

[0034] Preferably, the insertion rod 10 can be a cylindrical rod, and the socket cylinder 11 can be a cylindrical sleeve with an inner diameter slightly larger than the cylindrical rod, so that the insertion rod 10 can be inserted into the socket cylinder 11. The socket cylinder 11 can make an axial lifting movement relative to the insertion rod 10, or can rotate around its axis. After the lifting and rotation adjustments are in place, the insertion rod 10 can be locked and positioned by screwing in a bolt, so as to drive the sleeve connecting rod 6 to lift or rotate synchronously, and further adjust the position of the cutting head of the gas cutting gun body 8.

[0035] Please refer to the appendix Figure 1 and the appendix Figure 2 , both ends of the crank handle base 1 are respectively provided with fixed brackets 12. The fixed brackets 12 are in an L-shaped structure. The vertical section of the fixed bracket 12 is fixed on the end face of the crank handle base 1, and the threaded rod 3 is rotatably penetrated and installed on the vertical section of the fixed bracket 12 through a rotating bearing seat.

[0036] Preferably, through holes are reserved on the vertical section of the fixing bracket 12 for installing the rotating bearing seat, and the threaded rod 3 passes through the rotating bearing seat, facilitating the manual control of the rotation of the threaded rod 3 relative to the handle base 1 and the fixing bracket 12, which can improve the installation reliability and rotation stability of the threaded rod 3.

[0037] Please refer to Appendix Figure 1 and Appendix Figure 2 , the bottom surface of the horizontal section of the fixing bracket 12 is slightly lower than the bottom surface of the handle base 1, and the horizontal section of the fixing bracket 12 is fixed on the workbench surface (not shown in the figure).

[0038] The horizontal section of the fixing bracket 12 is in surface contact with the workbench surface, with a large contact area, making the use stability of the entire tooling high. The fixing bracket 12 can also be reinforced on the workbench surface by means of bolt connection, etc., further ensuring the use stability of the entire tooling.

[0039] Please refer to Appendix Figure 1 and Appendix Figure 2 , on both sides of the top of the handle base 1, a pair of sliding block pressing plates 13 are respectively installed, and a guiding and limiting groove 14 is formed between the pair of sliding block pressing plates 13, enabling the mounting rod 9 to slide through the guiding and limiting groove 14.

[0040] The pair of sliding block pressing plates 13 can abut against the top of the sliding block 4, preventing the sliding block 4 from slipping out of the handle base 1 upwards. At the same time, the mounting rod 9 is restricted from both sides, preventing the mounting rod 9 from tilting.

[0041] The length directions of the sliding block pressing plates 13 and the guiding and limiting groove 14 are both parallel to the axial direction of the threaded rod 3, ensuring that the moving directions of the mounting rod 9 and the sliding block 4 are along the axial direction of the threaded rod 3.

[0042] Please refer to Appendix Figure 1 and Appendix Figure 2 , the usage method of the present utility model is as follows:

[0043] Install the entire tooling on a fixed plane such as the workbench surface or the ground beside the gas cutting position through the horizontal section of the fixing bracket 12. The operator holds the other end of the handle 2 and rotates the handle 2, causing the handle 2 to drive the threaded rod 3 to rotate forward or backward.

[0044] When the threaded rod 3 rotates forward, the sliding block 4 is driven by the screw thread transmission to move along the axial direction of the threaded rod 3 away from the handle 2. Similarly, when the threaded rod 3 rotates backward, the sliding block 4 is driven by the screw thread transmission to move along the axial direction of the threaded rod 3 towards the handle 2, thereby driving the large gas cutting gun body 8 and its cutting head to move synchronously.

[0045] Adjust the position of the telescopic adjustable gas cutting torch fixing rod 7 in the sleeve connecting rod 6, so as to drive the large gas cutting torch body 8 and its cutting head to move synchronously. After moving in place, insert bolts to lock the gas cutting torch fixing rod 7 and the sleeve connecting rod 6.

[0046] When the socket cylinder 11 rotates and moves up and down relative to the plugging rod 10, it drives the large gas cutting torch body 8 and its cutting head to rotate and move up and down synchronously. After rotating and moving to the position, insert bolts to lock the socket cylinder 11 and the plugging rod 10.

[0047] Through the above adjustment method, the gas cutting torch body 8 and its cutting head can have a movement adjustment range in three-dimensional space, so that the cutting head can accurately align with the starting point of the cutting line on the cut material.

[0048] During cutting, since the axial direction of the threaded rod 3 is parallel to the cutting line, by rotating the crank 2, the cutting head of the gas cutting torch body 8 can be driven to make a stable linear motion along the cutting line, thus ensuring the straightness of the cutting line and the flatness of the cutting surface.

[0049] The above is only the preferred embodiment of the present invention, and is not used to limit the protection scope of the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
