[0032] The specific arrangement and function of the limiting structure 6 and the adjusting structure 7 will be described in detail below.

[0033] like Figure 2 and Figure 3 As shown, the limiting structure 6 includes a fixing plate 601, which is fixedly connected to the surface of the universal wheel 5, and the surface of the fixing plate 601 slides through the limiting rod 602. The arc surface of the limiting rod 602 is covered with a spring 603, and the two ends of the spring 603 are respectively fixedly connected to the limiting rod 602 and the fixing plate 601. The surface of the universal wheel 5 is provided with two circular grooves 604, and the size of the limiting rod 602 is adapted to the size of the circular groove 604. One end of the limiting rod 602 is fixedly connected to a traction rope 605, and the end of the traction rope 605 away from the limiting rod 602 is fixedly connected to a ball 606. The movement of the ball 606 will drive the traction rope 605 to move, and the movement of the traction rope 605 will drive the limiting rod 602 to move.

The arc surface of the limit rod 602 is provided with a groove 607, and the side wall of the fixed plate 601 is slidably penetrated with a latch 608, the size of the latch 608 is adapted to the size of the circular groove 604, and the latch 608 is pressed to insert the latch 608 into the groove 607, and the latch 608 reaches the position of limiting the limit rod 602, so as to facilitate the function of rotating the universal wheel 5 at will, thereby improving the practicality of the universal wheel 5. The end of the limit rod 602 away from the traction rope 605 is fixedly connected with an arc block 609, and the surface of the universal wheel 5 is provided with a guide groove 610, which is connected to the circular groove 604, and the arc block 609 will slide along the inner wall of the guide groove 610, and the arc block 609 can reduce the friction between the limit rod 602 and the guide groove 610, so as to facilitate the adjustment of the angle of the universal wheel 5, and the guide groove 610 can limit the rotation direction of the limit rod 602.

[0034] like Figure 4 and Figure 5As shown, the adjustment structure 7 includes a rectangular box 71, which is fixedly connected to the surface of the body 1. The inner wall of the rectangular box 71 is rotatably connected with a threaded rod 72, one end of the threaded rod 72 penetrates the rectangular box 71, and the arc surface of the threaded rod 72 is threadedly connected with a driving block 73. The surface of the driving block 73 is fixedly connected with a rectangular plate 74, and the side of the rectangular plate 74 away from the driving block 73 is fixedly connected with a handle 75.

[0035] Working principle: when it is necessary to control the moving direction of the nitrogen generator, first pull the ball 606, the movement of the ball 606 will drive the traction rope 605 to move, the movement of the traction rope 605 will drive the limit rod 602 to move, the limit rod 602 will slide in the fixed plate 601 and gradually come out of the circular groove 604, the movement of the limit rod 602 will stretch the spring 603, at this time the spring 603 is in a stretched state, then turn the universal wheel 5, the rotation of the universal wheel 5 will drive the fixed plate 601 to rotate, the rotation of the fixed plate 601 will drive the limit rod 602 to rotate, when the limit rod 602 rotates to a suitable position, release the ball 606, the limit rod 602 will move towards the direction close to the guide groove 610 with the help of the contraction force of the spring 603, The movement of the limiting rod 602 will drive the arc block 609 to move until the arc block 609 is tightly fitted against the inner wall of the guide groove 610, and then the fixing plate 601 continues to rotate. At this time, the arc block 609 will slide along the inner wall of the guide groove 610. When the arc block 609 is rotated to a suitable position, the limiting rod 602 will slide into the circular groove 604 opened at the corresponding position with the help of the contraction force of the spring 603. When there is no need to limit the moving direction of the universal wheel 5, first pull the ball 606, and the movement of the traction rope 605 with the help of the ball 606 will drive the limiting rod 602 to move. When the limiting rod 602 moves to a suitable position, press the pin 608 to insert the pin 608 into the groove 607, and the pin 608 reaches the function of limiting the position of the limiting rod 602.

[0036] When the height of the handle 75 needs to be adjusted, first rotate the threaded rod 72. The threaded rod 72 will rotate inside the rectangular box 71. The threaded rod 72 will drive the drive block 73 to move with the help of the thread. The movement of the drive block 73 will drive the rectangular plate 74 to move. When the rectangular plate 74 moves, it will drive the two baffles 76 to slide along the surface of the rectangular box 71. The baffles 76 limit the movement path of the rectangular plate 74, thereby preventing the rectangular plate 74 from shaking when moving. The movement of the rectangular plate 74 will drive the handle 75 to move, and the movement of the handle 75 will drive the protective cover 77 to move.
