In the first state, the limiting device is not operated (not in contact with the rod 32 or the second support 232), and the rod 32 moves relative to the second bracket 2 under the drive of the first telescopic member 31; when the rod 32 moves relative to the second bracket 2 to the limit device contacts the rod 32 and the second bracket 2 respectively, the rod 32 is switched from the first state to the second state, in the second state, the rod 32 and the second bracket 2 are linked, and the first telescopic piece 31 drives the rod 32 to drive the second bracket 2 to rotate relative to the first bracket 1.

When the first telescopic member 31 performs shortening movement (shortening movement, the second bracket 2 is extended) and drives the outer end of the lever 32 (i.e., the end where the fourth shaft 64 is located) to move toward the side close to the first bracket 1 (i.e., rotate toward the rear side of the second bracket 2 about the fifth shaft 65), when the lever 32 moves to the first position, the first stopper 51 contacts the lever 32 and the second support 232, respectively, and when the lever 32 is switched from the first state to the second state, as shown in fig. 12, when the first telescopic member 31 continues to move (shortening movement), the lever 32 is interlocked with the second bracket 2, and the front end of the second bracket 2 moves toward the side close to the first bracket 1 about the first shaft 61 (leftward front end movement), so that the extension of the second bracket 2 is achieved. As shown in fig. 12, in the first position, the transmission angle at which the first telescopic member 31 drives the second bracket 2 to rotate is larger, and the transmission efficiency is higher (relative to the case where the lever 32 is not provided). As shown in fig. 11, in the folded state, the length direction of the second rack body 21 substantially coincides with the width direction of the first rack body 11, and the width direction of the second rack body 21 coincides with the vertical direction.

In an embodiment of the limiting device, the limiting device comprises a second limiting member (not shown in the figure), which is located at a side of the rod 32 away from the first bracket 1; the second limiting member is connected with the lever 32, or the second limiting member is connected with the second bracket 2. For example, the second stopper is connected to the first support 231 near one side in the fixing.
