A magnetic rotating shaft 607 is provided at the upper end of the second connecting rod 606. The lower end appearance structure of the magnetic rotating shaft 607 is cylindrical, and the outer side surface of the magnetic rotating shaft 607 is in contact with the outer side surface of the third hole 608. The upper end width of the magnetic rotating shaft 607 is greater than the lower end width of the magnetic rotating shaft 607, so that the magnetic rotating shaft 607 will not drive the second telescopic rod 602 to move. A third hole 608 is provided inside the left side of the second telescopic rod 602, and the magnetic rotating shaft 607 is nested in the inner side of the third hole 608.

[0023] The limiting mechanism 7 includes a first support plate 701 fixedly connected to the upper surface of the base 1, a second groove 702 is arranged on the inner side of the first support plate 701, the inner upper surface of the second groove 702 is connected with a first hole 703, a second support plate 704 is slidably connected to the inner side of the middle of the second groove 702, a first limiting rod 705 is arranged on the inner side of the first hole 703, the second support plate 704 and the first limiting rod 705 are connected in a fixed manner, a third groove 706 is arranged on the rear side of the second groove 702, and the third A first slide plate 707 is provided on the inner side of the groove 706, and the connection mode of the first slide plate 707 and the first support plate 701 is a vertical sliding connection. A first limiting groove 708 is provided inside the lower end of the rotating motor 5, and a second limiting groove 709 is connected on the lower inner wall of the third groove 706, and a third limiting groove 710 is connected on the upper inner wall of the third groove 706. The cooperation mode of the second limiting groove 709 and the third limiting groove 710 is a clearance cooperation. The first holes 703 are equidistantly distributed on the inner side of the first support plate 701, and the ... The inner side of a hole 703 is fitted with the outer side of the first limiting rod 705, the first limiting groove 708 and the first limiting rod 705 are matched in a gap manner, and the upper end surface of the first limiting rod 705 is an inclined surface, and the middle end of the first limiting rod 705 is a rectangular parallelepiped, so that when the rotating motor 5 rotates, it will rotate on the inner side of the first limiting rod 705. A fourth groove 711 is provided on the inner side of the first slide plate 707, and a push plate 712 is provided on the inner side of the fourth groove 711. The lower end of the push plate 712 is fixedly connected to a spring 7 13. A fifth groove 714 is provided inside the push plate 712, and a second hole 716 is connected to the inner wall of the fourth groove 711. A second limiting rod 715 is provided on the inner side of the second hole 716. The second limiting rod 715 is connected to the push plate 712 in a sliding manner, and the left side surface of the second limiting rod 715 is an inclined surface, and the second limiting rod 715 and the third limiting groove 710 are matched in a clearance manner, so that when the push plate 712 moves downward, the second limiting rod 715 can be pushed to move inward.

[0024] When the chassis guard plate needs to be installed, the threaded rod is placed above the magnetic rotating shaft 607, and the air cylinder 2 is started to drive the air rod 3 to move upward, driving the chassis guard plate above the supporting plate 4 to move upward. At this time, the air rod 3 drives the second telescopic rod 602 and the first telescopic rod 601 to move upward, so that the first telescopic rod 601 pushes the upper end of the magnetic rotating shaft 607 to move upward, so that the magnetic rotating shaft 607 and the threaded rod move upward to the inside of the corresponding threaded hole on the vehicle body, and the rotating motor 5 is started to drive the first rotating shaft 603 and the second connecting rod 606 arranged on the inner side of the first connecting rod 604 to move upward, so that the magnetic rotating shaft 607 rotates. Because the magnetic rotating shaft 607 itself is magnetic, the threaded rod will move upward when it rotates inside the threaded hole, driving the magnetic rotating shaft 607 to move upward, so that the magnetic rotating shaft 607 can continuously provide rotational force to the threaded rod, so that the threaded rod continues to move upward, thereby realizing automatic installation of the chassis guard plate.

[0025] When it is necessary to adapt to chassis guard plates of different sizes, the push plate 712 is pushed downward. Since the connection method between the second limit rod 715 and the push plate 712 is a sliding connection, and the left side surface of the second limit rod 715 is an inclined surface, the second limit rod 715 moves inward, causing the second limit rod 715 to lose the limit on the first support plate 701, pushing the first slide plate 707 to move downward, driving the second support plate 704, so that the first limit rod 705 moves out of the first limit groove 708, and then the rotating motor 5 can be pushed to a different position. After the position movement is completed, the push plate 712 is pushed again to make the push plate 712 lose the limit again, and pull the push plate 712 to move upward. The second support plate 704 is driven to move upward, and the first limiting rod 705 is driven to return to the inner side of the first limiting groove 708 again, so as to limit the rotating motor 5 again. Because the upper end face of the first limiting rod 705 is an inclined face, the first limiting rod 705 can move along the oblique side of the first limiting rod 705 to the inner side of the first limiting groove 708 when contacting the edge of the first limiting groove 708, so as to facilitate limiting. Because the left and right directions and the front and back directions of the rotating motor 5 are all limited, the rotating motor 5 will not be displaced when it vibrates, thereby reducing the situation where the bolts are not removed smoothly. Because the rotating motor 5 is limited, it does not require much friction for limiting, so that the rotating motor 5 is also easier to move when it moves.
