[0037] Example two
[0038] Please refer to Figures 7-9 The device can be applied to a construction site with stairs and assist in material carrying, in use, the telescopic rod 6 is pulled out, the material carrier 3 is stretched and opened to
[0039] Specifically, refer to Figure 1 、 Figure 3 , Figure 5 By setting up a pull rod 5, when the rack 3 is in working condition, the two ends of the pull rod 5 are connected to the sides of the rack 3 and the main frame 1, and the pull rod 5 provides tension to the rack 3, thereby improving the load-bearing capacity.

At the ends of the first rod 51 and the second rod 52 that are close to each other, one is provided with a hooking part 510, and the other is provided with a hooking post 520 that engages with the hooking part 510. The axis of the hooking post 520 is parallel to the axis of the first pin 40. For example, the first rod 51 is hinged to the shelf 3 via the second pin 511, and the second rod 52 is hinged to the main frame 1 via the third pin 521. The end of the first rod 51 has a bent portion that bends away from the shelf 3, and the hooking part 510 is located at the end of the bent portion. Specifically, the hooking part 510 is a hook located at the end of the bent portion.

Figure 1 work status and Figure 6 Switching between storage states.
[0041] Furthermore, as a preferred embodiment, to prevent the second rod 52 from rotating towards the combined wheel 2 and colliding with it, thus hindering the rotation of the combined wheel 2, a blocking member 11 is provided protruding from the side of the main frame 1 between the hinge point of the pull rod 5 and the second end. Specifically, the blocking member 11 is a column protruding from the side of the main frame 1, which can block the end of the second rod 52, preventing the second rod 52 from deflecting towards the combined wheel 2 from the side closer to the second end.
[0042] Furthermore, as a specific implementation method, in Figure 6 The storage configuration shown is for easy storage and to prevent the first rod 51 and the second rod 52 from swinging freely. (Refer to...) Figure 3 , Figure 9The side surface of the main frame body 1 and the side surface of the object rack 3 are provided with positioning assemblies 53, and the positioning assembly 53 on the main frame body 1 is arranged between the position where the pull rod 5 is hinged to the main frame body 1 and the first end. Through the positioning assembly 53, the first rod 51 is positioned when the first rod 51 swings to the position coinciding with the side surface of the object rack 3, and the second rod 52 is positioned when the second rod 52 swings to the position coinciding with the side surface of the main frame body 1, so that the random swinging of the first rod 51 and the second rod 52 can be prevented, and the storage is more convenient.

Specifically, under the elastic force of the compression spring 532, the ball 531 can be abutted on the through hole 533, the ball 531 can partially extend out of the through hole 533 and partially protrude from the end surface of the columnar piece 530, the radius of the through hole 533 is smaller than the radius of the ball 531, and the ball 531 cannot pass through the through hole 533. Through this arrangement, when the first rod 51 and the second rod 52 are stored to coincide with the side surface of the main frame body 1 and the object rack 3, the ball 531 can be squeezed inwardly and retracted, and then the compression spring 532 provides damping force to the surface of the first rod 51 and the second rod 52, so that the limiting purpose is achieved. The mounting groove is a cylindrical groove, and the columnar piece can be threadedly connected with the mounting groove.
