[0035] Embodiment 2

[0036] Reference Figure 1 , Figure 4 and Figure 5A new auxiliary ladder, a fixing mechanism includes a connecting rod 17, a second sliding plate 18, a lifting handle 19, a spring 20 and a clamping rod 21, the inner sides of the two second connecting plates 5 located on the same side are rotatably connected to a connecting rod 17, the inner side of the connecting rod 17 is slidably connected to the second sliding plate 18, a lifting handle 19 is fixed to one side of the second sliding plate 18, the lifting handle 19 is slidably connected to the connecting rod 17, the outer side of the lifting handle 19 is sleeved with a spring 20, the spring 20 is located inside the connecting rod 17, and two clamping rods 21 are fixed to the other end of the second sliding plate 18, and the two clamping rods 21 are clamped with the two second connecting plates 5; the fixing mechanism can prevent the second connecting plate 5 from loosening or falling off, and avoid safety accidents such as ladder collapse caused by failure of the second connecting plate 5.

[0037] Guide grooves 16 are provided on the inner sides of the two first fixing plates 11, and the limiting plate 10 is slidably connected to the first fixing plates 11 through the guide grooves 16. The guide grooves 16 have a role of limiting and guiding the limiting plate 10. Two snap-in grooves 22 are provided on the inner side of one end of the second connecting plate 5. The size of the snap-in grooves 22 is the same as the outer size of the snap-in rod 21. The opening of the snap-in grooves 22 is conducive to the fixation of the two second connecting plates 5 by the fixing mechanism.

[0038] The top of the pedal 3 is provided with anti-skid patterns, which can increase the roughness of the surface of the pedal 3, thereby increasing the friction between the sole and the pedal 3, and can effectively prevent slipping and falling.

[0039] The use process of a new auxiliary ladder provided by the utility model is as follows: the auxiliary ladder is placed flat on the ground, and the two first connecting frames 2 are rotated. Since the second connecting plate 5 is rotatably connected to the first fixed rod 4 and the first fixed rod 4 is fixed to the first connecting frame 2, and the two second connecting plates 5 located at the same side end are rotatably connected to the corresponding connecting rod 17, the rotation of the two first connecting frames 2 drives the two second connecting plates 5 to rotate. When the two first connecting frames 2 are opened to the maximum angle, the two second connecting plates 5 located on the same side are located on the same horizontal line. At this time, the clamping grooves 22 opened on the two second connecting plates 5 located on the same side overlap. At this time, the connecting rod 17 is rotated. Since the second sliding plate 18 is slidably connected to the connecting rod 17, the rotation of the connecting rod 17 drives the second sliding plate 18 to rotate. When the two lifting handles 19 fixedly connected to the second sliding plate 18 overlap with the clamping grooves 22, the second sliding plate 18 moves under the action of the elastic force of the spring 20, and the movement of the second sliding plate 18 drives the clamping rod 21 to move, so that the two clamping rods 21 are plugged with the two second connecting plates 5 through the clamping grooves 22;

[0040] The fixing mechanism can prevent the second connecting plate 5 from loosening or falling off, thereby avoiding safety accidents such as ladder collapse caused by failure of the second connecting plate 5;

[0041] The knob 8 is turned. Since the knob 8 is fixed to the rotating threaded rod 7 and the rotating threaded rod 7 is rotatably connected to the two second connecting frames 6, the rotation of the knob 8 drives the rotating threaded rod 7 to rotate, so that the first sliding plate 9 threadedly connected to the rotating threaded rod 7 moves accordingly. Since the limiting plate 10 is fixed to the first sliding plate 9 and the limiting plate 10 is rotatably connected to the third connecting plate 12, the movement of the first sliding plate 9 drives the limiting plate 10 to move, so that the third connecting plate 12 rotatably connected to the limiting plate 10 also moves accordingly. In addition, the two third connecting plates 12 are both rotatably connected to the second fixed rod 13 and the second fixed rod 13 is fixed to the fourth connecting plate 14, so that the rotation of the third connecting plate 12 drives the fourth connecting plate 14 to rotate, so that the second fixed plate 15 fixed to the fourth connecting plate 14 also rotates accordingly. At this time, the auxiliary ladder is erected. At this time, the second fixed plate 15 is in contact with the ground, and the auxiliary ladder can be used normally.

[0042] The design of the stabilizing mechanism can prevent the ladder from sliding or tipping over easily under load, thereby greatly improving the stability of the ladder during work and providing a more stable working platform for decorators. Decorators do not need to worry too much about the safety risks caused by the shaking of the ladder, and can focus more on the decoration work at hand.

[0043] The preferred embodiments of the utility model disclosed above are only used to help explain the utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the utility model, so that technicians in the relevant technical field can well understand and use the utility model. The utility model is limited only by the claims and their full scope and equivalents.
