Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 - Figure 4As shown, an inverter manual welding machine comprises a box body 1, a handle 2 is fixedly connected to the top of the box body 1, two groups of jacks 3 are opened at the bottom of one side of the box body 1, a connector 4 is inserted into the jack 3, a welding wire 5 is fixedly connected to one end of the connector 4, a fixing mechanism is arranged at the top of the jack 3, the fixing mechanism comprises a moving groove 6, the moving groove 6 is arranged at the top of the jack 3, the moving groove 6 is opened on one side of the box body 1, screws 7 are rotatably connected to the two ends of the moving groove 6, a rotating block 8 is arranged at the front and rear of one side of the box body 1, the output shaft of the rotating block 8 passes through the box body 1 and is fixedly connected to one end of the screw 7, moving blocks 9 are threadedly connected to the outer sides of the two ends of the screw 7, and the moving block 9 is fixedly connected to the fixed block 10;

[0022] During operation, when performing welding work, it is necessary to insert the connector 4 at one end of the welding wire 5 into the socket 3, and then rotate the rotating block 8 to drive the screw 7 to rotate, so that the two groups of moving blocks 9 drive the two groups of fixed blocks 10 to move toward each other, and when the two groups of fixed blocks 10 move toward each other and are close to the connector 4, the rotating block 8 is stopped. When the two groups of fixed blocks 10 move toward each other and are close to the connector 4, they are just sleeved on the outside of the connector 4, and the card block 13 on the inside of the fixed block 10 enters the card groove 12 on the outside of the connector 4. At this time, the connector 4 cannot be pulled out, thereby achieving the fixation of the connector 4.

[0023] Further, such as Figure 3 As shown, a stopper 11 is fixedly connected to the outer side of the middle of the screw rod 7, and the threads at both ends of the screw rod 7 are opposite;

[0024] During operation, the threads at both ends of the screw rod 7 are opposite to each other so that when the screw rod 7 rotates, the moving blocks 9 at both ends of the screw rod 7 move toward each other, so that the two sets of fixed blocks 10 can move toward each other and then be close to the connector 4.

[0025] Further, such as Figure 3 As shown, the cross-section of the fixing block 10 is semicircular, the size of the fixing block 10 is adapted to the size of the connector 4, a card slot 12 is provided on the outer side of the connector 4, and a card block 13 is fixedly connected to one side of the fixing block 10 close to the connector 4, and the size of the card block 13 is adapted to the card slot 12;

[0026] During operation, when the two sets of fixing blocks 10 move toward each other and are close to the connecting head 4, they are just sleeved on the outside of the connecting head 4, and the clamping block 13 on the inside of the fixing block 10 enters the clamping groove 12 on the outside of the connecting head 4. At this time, the connecting head 4 cannot be pulled out, and the connecting head 4 is fixed. In this way, the welding worker will not cause the connecting head 4 to fall off during welding work.

[0027] Furthermore, if Figure 3 As shown, the moving block 9 is inside the moving groove 6, and the size of the moving block 9 is adapted to the moving groove 6;

[0028] During operation, the rotation of the screw 7 will cause the moving block 9 to have the same tendency to rotate. Since the size of the moving block 9 is adapted to the moving groove 6, the tendency of the moving block 9 to rotate will be hindered by the moving groove 6. Also, due to the characteristics of the threaded connection between the moving block 9 and the screw 7, the moving block 9 can move on the screw 7 as the screw 7 rotates.

[0029] Further, such as Figure 4 As shown, the front of the box body 1 is provided with an assembly groove 14, and the four corners of the front of the assembly groove 14 are provided with positioning grooves 15. A storage box 16 is arranged inside the assembly groove 14, and a positioning block 17 is arranged inside the positioning groove 15. The positioning block 17 is fixedly connected with the storage box 16. A threaded hole 18 is arranged inside the positioning groove 15, and a round hole 19 is arranged at the front of the positioning block 17. A screw 20 is arranged inside the round hole 19, and the screw 20 passes through the round hole 19 and is threadedly connected with the threaded hole 18;

[0030] During work, in order to facilitate the storage of the welding wire 5, the welding wire 5 can be placed inside the storage box 16 for storage, so that the welding worker only needs to carry the box 1 to complete the welding work. When welding work is needed, the welding wire 5 needs to be taken out of the storage box 16. At this time, the screw 20 needs to be rotated, and the screw 20 needs to be removed from the inside of the threaded hole 18, and then taken out from the round hole 19 at the front of the positioning block 17. In this way, the four groups of screws 20 are removed in sequence to release the fixation of the storage box 16. After taking out the storage box 16, the welding wire 5 is taken out, and subsequent welding work can be carried out. When the welding work is completed, it is only necessary to put the welding wire 5 into the storage box 16, and push the storage box 16 into the assembly groove 14. At this time, the positioning block 17 enters the positioning groove 15, and the round hole 19 is aligned with the threaded hole 18. The screw 20 is passed through the round hole 19 and threadedly connected with the threaded hole 18 to complete the fixation of the storage box 16.

[0031] Further, such as Figure 1 As shown, a handle 21 is provided at the front of the storage box 16, and the handle 21 is fixedly connected to the storage box 16;

[0032] During operation, after the storage box 16 is released from the fixing position, the storage box 16 can be conveniently and easily pulled out of the box body 1 through the handle 21 , so as to take out or store the welding wire 5 .

[0033] Working principle: in order to store the welding wire 5 conveniently, the welding wire 5 can be placed inside the storage box 16 for storage, so that the welding worker only needs to carry the box 1 to complete the welding work. When welding work is needed, the welding wire 5 needs to be taken out from the storage box 16. At this time, the screw 20 needs to be rotated to remove the screw 20 from the inside of the threaded hole 18, and then taken out from the round hole 19 at the front of the positioning block 17. In this way, the four groups of screws 20 are removed in sequence to release the fixation of the storage box 16. After taking out the storage box 16, the welding wire 5 can be taken out, and subsequent welding work can be carried out. At this time, the connector 4 at one end of the welding wire 5 needs to be inserted into the jack 3, and then the rotating block 8 is rotated to drive the screw 7 to rotate, so that the two groups of moving blocks 9 drive the two groups of fixed blocks 10 to move toward each other. Move, when the two groups of fixing blocks 10 move to be close to the connecting head 4, the rotating block 8 stops rotating, and when the two groups of fixing blocks 10 move toward each other to be close to the connecting head 4, they are just sleeved on the outside of the connecting head 4, and the card block 13 on the inside of the fixing block 10 enters the card groove 12 on the outside of the connecting head 4. At this time, the connecting head 4 cannot be pulled out, and the fixing of the connecting head 4 is achieved. In this way, the welding worker will not make the connecting head 4 fall off during the welding work. After the welding work is completed, it is only necessary to put the welding wire 5 into the storage box 16, and push the storage box 16 into the assembly groove 14. At this time, the positioning block 17 enters the positioning groove 15, and the round hole 19 is aligned with the threaded hole 18, and the screw 20 is passed through the round hole 19 and threadedly connected with the threaded hole 18 to complete the fixing of the storage box 16.
