When the arc welding equipment is not used, the protection shell 201 on the unfolded auxiliary mechanism 2 and the protective frame composed of the two auxiliary rectangular plates 204 and the main rectangular plate 203 in the fixed state can protect the arc welding equipment in the placement state.

[0043] The effect and working principle of the whole mechanism are as follows:

[0044] Preparation stage, first remove the entire auxiliary mechanism 2 (except two connecting plates 205) from the welding machine box 101, and then remove the two side plates of the welding machine box 101 (as shown in Figure 5 The space composed of the welding machine box 101 and the partition plate 116 (the first space, which has the display module 103) is connected according to the electrical connection safety criteria and the drawing requirements, and then the power supply line 121, the ground clamp 123 connected with the connecting line 122, and the welding handle 124 connected with the connecting line 122 inside the space are taken out (these taken-out components will be stored inside the first space when the entire arc welding equipment is not in use), and then the two side plates of the welding machine box 101 are installed back to the original position, and then the removed auxiliary mechanism 2 (except the two connecting plates 205) is installed back to the original position;

[0045] When the arc welding equipment is needed to be used, one of the hand knobs 214 is rotated first, and the rotating hand knob 214 drives the corresponding take-up reel 213 to rotate stably under the cooperation of the corresponding main rectangular plate 203 and the corresponding auxiliary rectangular plate 204. Then, the rotating take-up reel 213 winds the single-end rope 222 and one end of the three-end rope 221 under the cooperation of the corresponding first auxiliary groove 207, the corresponding second auxiliary groove 208 and the corresponding perforated plate 215. Then, the continuously wound single-end rope 222 drives the first clamping rod 209 to move, and the continuously wound three-end rope 221 also drives the two second clamping rods 210 to move. Then, the moving first clamping rod 209 and the two second clamping rods 210 stretch the corresponding springs 211 under the cooperation of the corresponding second auxiliary groove 208 and the corresponding first auxiliary groove 207. When the clamping end of the first clamping rod 209 and the clamping end of the two second clamping rods 210 are moved out of the rectangular hole 202 in the inner wall of the welding machine box 101, the rotation of the hand knob 214 is stopped. Then, the hand knob 214 is kept stationary, and the main rectangular plate 203 is rotated. Then, the rotating main rectangular plate 203 drives the auxiliary rectangular plate 204 and all the components thereon to rotate simultaneously. When the main rectangular plate 203 is rotated to the horizontal position, the main rectangular plate 203 is kept stationary, the hand knob 214 is reversed, and the single-end rope 222 and the three-end rope 221 are unwound. Then, under the cooperation of the rebound force of the stretched springs 211, the corresponding first auxiliary groove 207 and the corresponding second auxiliary groove 208, the first clamping rod 209 is reset to the original position. When the first clamping rod 209 is reset to the original position, the clamping end of the first clamping rod 209 is just inside the circular hole of the corresponding perforated block 206. Then, the force applied to the main rectangular plate 203 is released. Then, the two heavy blocks 219 are taken out from the corresponding two placement grooves 216 under the cooperation of the two rectangular grooves 220. Each moving heavy block 219 drives the corresponding folded cloth 218 to move. When the two folded cloths 218 are completely unfolded, the movement of the two heavy blocks 219 is stopped. Then, the above steps are repeated to rotate and fix the other main rectangular plate 203. The two folded cloths 218 are also completely unfolded. If the arc welding equipment is used outdoors, rain will not fall on the connection between the connecting line 122 and the interface 102 under the cooperation of the main rectangular plate 203, the auxiliary rectangular plate 204, the folded cloth 218, the rectangular strip 217 and the heavy block 219. When the arc welding equipment is not used, the protection shell 201 on the unfolded auxiliary mechanism 2 and the protective frame composed of the two auxiliary rectangular plates 204 and the main rectangular plate 203 in the fixed state can protect the arc welding equipment in the placement state.

[0046] When the arc welding stage is needed to arc weld the parts that make up the rotary cultivator brake box together, at this time the installation end of the power cord 121 is docked with the installation end of the socket 108, then the plug of the power cord 121 is docked with the power supply strip, then the on-off switch button 106 is pressed, after that the alternating current of the power supply strip will pass through the cooperation of the power cord 121, the socket 108 and the closed air switch 111 to the step-down transformer 115, then the alternating current entering the step-down transformer 115 will be reduced to the low-voltage alternating current required for arc welding, then the low-voltage alternating current output by the step-down transformer 115 will be transmitted to the rectifier 112, when the low-voltage alternating current is transmitted to the rectifier 112, at this time the rectifier 112 will convert the input low-voltage alternating current into direct current, then the direct current will be transmitted to the inverter board 118, then the inverter board 118 will process the direct current using the filter capacitor integrated on it, after that part of the processed direct current will be processed by the auxiliary module integrated on the inverter board 118 to match the voltage of the control board 113 to supply power to the control board 113, at this time the control board 113 that gets power will light up the display module 103, then use the adjustment knob 104 (current), the control board 113 and the display module 103 to cooperate to set the current, then the control board 113 processes the set current data signal and transmits the processed current data signal to the inverter board 118, when the inverter board 118 receives the current data signal, at this time the inverter board 118 will convert another part of the direct current into high-frequency alternating current, then the high-frequency alternating current will be reduced to the low-voltage alternating current required for welding by using the inverter high-frequency transformer integrated on the inverter board 118, then the low-voltage alternating current will be converted into direct current by using the rectifier module integrated on the inverter board 118, after that the twice-rectified direct current welding power will be transmitted to one of the interfaces 102 (corresponding to the welding handle 124), then through the connecting wire 122 connected to it, to the welding handle 124, then fix the ground clamp 123 on one of the parts that make up the rotary cultivator brake box, and finally clamp the special welding rod on the chuck at the front end of the welding handle 124, when everything is ready, at this time the welder holds the welding handle 124, while the other part is docked with the part held by the ground clamp 123, then touches the end of the welding rod to the connection between the two parts, then uses the high-temperature heat generated by the electric arc discharge to melt the welding rod and the welded parts, then uses the melted welding rod to fix the two parts together, then repeats the above steps until the rotary cultivator brake box is made, at the same time, the temperature sensor 114 will also monitor the temperature of the space inside the welding machine box 101 and the partition 116 (the second space, the space inside has the rectifier 112) in real time, and transmit the temperature data detected each time to the control board 113 in the form of an electrical signal, then the control board 113 compares the received temperature data with the temperature threshold set by the control board 113 (set in advance),When the temperature data received by the control board 113 is lower than the temperature threshold set by the control board 113, the control board 113 does not start the fan 109, and vice versa, that is, the fan 109 is used to quickly remove the temperature inside the second space.

[0047] Wherein, the welding machine box 101 is made of multiple plates assembled by screws, when the indicator light 105 is on, it means that the electric arc welding equipment is running normally, otherwise the air switch 111 is tripped and powered off or the electric arc welding equipment is malfunctioning, the rubber handle 3 can move the protective shell 201, and the protective shell 201 can move the welding machine box 101 by cooperating with the connecting plate 205 connected thereto.

[0048] Wherein, the interface 102, the display module 103, the adjusting knob 104, the indicator light 105, the switch button 106, the socket 108, the fan 109, the air switch 111, the rectifier 112, the control board 113, the temperature sensor 114, the step-down transformer 115, the inverter board 118, the power cord 121, the connecting wire 122, the ground clamp 123 and the welding handle 124 are all prior art, and their models can be selected according to actual conditions, and will not be explained here.
