[0027] Referring to Figures 2-4 , the end of the cable 22 close to the male plug 21 is fixedly provided with a conical ring 23, and one side of the cutting power mainframe 1 is provided with an anti-falling mechanism for preventing the cable 22 from falling off, the anti-falling mechanism comprises a connecting pipe 3 fixedly arranged on one side of the cutting power mainframe 1 for covering the male plug 21 and the female plug 2, and a blocking rod 31 slidingly arranged on the top of one end of the connecting pipe 3 for resisting the conical ring 23 entering the connecting pipe 3 to prevent reverse movement, the top of the connecting pipe 3 is provided with a tension spring 33 for pulling the blocking rod 31 to the inside of the connecting pipe 3, the conical ring 23 is matched with the inside of the connecting pipe 3, the conical ring 23 is located between the male plug 21 and the blocking rod 31, the connecting pipe 3 can cover the male plug 21 and the female plug 2 to protect the male plug 21 and the female plug 2 and limit the conical ring 23 matched with the inside, and the tension spring 33 can connect the blocking rod 31 and the connecting pipe 3.

[0028] Referring to Figures 2-4The bottom of the stop lever 31 is provided with an inclined surface for guiding the upward movement of the stop lever 31 when the tapered ring 23 is inserted into the connecting pipe 3. When the male plug 21, the cable 22 and the tapered ring 23 are inserted into the connecting pipe 3 for connecting the cable 22 with the cutting power supply main machine 1, the outer inclined surface of the tapered ring 23 will abut against the inclined surface at the bottom of the stop lever 31. With the continuous insertion of the cable 22, the tapered ring 23 will automatically push the stop lever 31 upward and away from the tapered ring 23 through the inclined surface, and then quickly move downward under the tension of the tension spring 33 and abut against the side of the tapered ring 23 away from the male plug 21, so as to stop and fix the tapered ring 23 in the connecting pipe 3. With the continuous insertion of the cable 22, the male plug 21 can be inserted into the female plug 2.

[0029] Referring to Figures 2-4 The top of the stop lever 31 is fixedly provided with a lifting plate 32 above the connecting pipe 3. The tension spring 33 is fixedly connected between the top of the connecting pipe 3 and the bottom of the lifting plate 32. The top of the connecting pipe 3 is fixedly provided with a limiting rod 4 which penetrates through the top and extends to the outside of the lifting plate 32. The lifting plate 32 can connect the stop lever 31, the tension spring 33 and other components. The limiting rod 4 can be a square rod which can limit the lifting plate 32 to move only up and down. The user can lift the lifting plate 32 upward to move the stop lever 31 upward, so that the tapered ring 23 and other components are released from the fixing. At this time, the male plug 21 and the cable 22 can be pulled out from the side of the cutting power supply main machine 1 to disassemble the cable 22.

[0030] Referring to Figures 2-4 The top of the connecting pipe 3 is fixedly provided with a fixed ring 36. A one-way air inlet valve 37 is fixedly installed in an air inlet hole formed in one side of the fixed ring 36. The top of the connecting pipe 3 is provided with a blowing mechanism for blowing and cleaning the female plug 2 after the stop lever 31 moves downward. The blowing mechanism comprises a bellows 34 fixedly arranged between the top of the fixed ring 36 and the bottom of the lifting plate 32, and an exhaust pipe 35 fixedly arranged between the female plug 2 and the top of the connecting pipe 3 and communicated with the bellows 34. The tension spring 33 is located between the inside of the bellows 34 and the fixed ring 36. The fixed ring 36 can connect the connecting pipe 3 and the bellows 34. The one-way air inlet valve 37 allows the external air to enter only into the inside of the fixed ring 36 and the bellows 34. The bellows 34 and the fixed ring 36 can cover the tension spring 33 to protect the tension spring 33.

[0031] After the male plug 21 and the cable 22 are pulled out from the side of the cutting power supply main machine 1, the lifted lifting plate 32 can be put down. At this time, the lifting plate 32 will quickly descend under the tension of the tension spring 33 to compress the bellows 34, so that the air in the bellows 34 and the fixed ring 36 enters the female plug 2 through the exhaust pipe 35 to blow away the dust and other foreign matters attached to the pins in the female plug 2 by air force, thereby blowing and cleaning the female plug 2.

[0032] With reference to Figures 1-2 The cutting power supply host 1 is fixedly installed with a plurality of casters 11 at the bottom corners, a plurality of heat dissipation holes are formed in the side wall of the cutting power supply host 1, and a winding wheel 12 for winding and unwinding the cable 22 is rotatably arranged at one side of the cutting power supply host 1. A handle 13 is fixedly arranged at the side edge of the winding wheel 12. The casters 11 can be used to push the cutting power supply host 1 to move, the heat dissipation holes can be used to ventilate and dissipate heat for the internal components of the cutting power supply host 1. After the winding wheel 12 is rotated by holding the handle 13, the cable 22 detached from one side of the cutting power supply host 1 can be wound on the winding wheel 12 to be arranged in order, thereby facilitating arrangement.

[0033] The implementation principle of the air plasma cutting power supply in the embodiment of the present application is as follows:

[0034] When the cable 22 and the cutting power supply host 1 need to be connected, the male plug 21, the cable 22 and the tapered ring 23 are inserted into the connecting pipe 3. The outer inclined surface of the tapered ring 23 abuts against the inclined surface at the bottom of the blocking rod 31. With the continuous insertion of the cable 22, the tapered ring 23 is guided by the inclined surface to automatically push the blocking rod 31 upward and away. Then, under the pulling force of the tension spring 33, the blocking rod 33 quickly moves downward and abuts against the side of the tapered ring 23 away from the male plug 21, thereby stopping and fixing the tapered ring 23 in the connecting pipe 3. In this way, when the cable 22 is accidentally kicked or tripped by the surrounding people, the cable 22 is not easy to fall off from the cutting power supply host 1, thereby ensuring the normal operation of the air plasma cutting power supply. With the continuous insertion of the cable 22, the male plug 21 can be inserted into the female plug 2, thereby quickly connecting the cable 22 and the cutting power supply host 1.

[0035] The user can lift the pull plate 32 upward to drive the blocking rod 31 to move upward, so that the tapered ring 23 and other components are disengaged from the fixing. At this time, the male plug 21 and the cable 22 can be pulled out from one side of the cutting power supply host 1, thereby detaching the cable 22.

[0036] After the male plug 21 and the cable 22 are pulled out from one side of the cutting power supply host 1, the lifted pull plate 32 can be lowered. At this time, under the pulling force of the tension spring 33, the pull plate 32 quickly descends to compress the bellows 34. The air in the bellows 34 and the inner part of the fixing ring 36 enters the female plug 2 through the exhaust pipe 35, thereby blowing away the dust and other foreign matters attached to the pins in the female plug 2 by air force, thereby cleaning the female plug 2 by blowing. After the winding wheel 12 is rotated by holding the handle 13, the cable 22 detached from one side of the cutting power supply host 1 can be wound on the winding wheel 12 to be arranged in order, thereby facilitating arrangement.

[0037] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
