When the movable support structure with the structure is used, when the goods on the transport vehicle need to be supported, the cantilever 40 can be switched to the extending position, so that the goods can be lapped on the cantilever 40. The cantilever arm 40 can be switched to the retracted position when there is no need to support the cargo on the trolley. Because the cantilever 40 is located in the accommodating space when the cantilever 40 is in the retracted position, the cantilever 40 is effectively prevented from extending out of the transfer vehicle and increasing the width of the transfer vehicle. Therefore, the movable support structure effectively solves the problem that the support structure of the transfer vehicle in the prior art is poor in service performance.

Alternatively, the arm 40 is perpendicular to the support frame 10 when the arm 40 is in the extended position, and the arm 40 is parallel to the support frame 10 when the arm 40 is in the retracted position. Through setting up like this, can guarantee that lapped goods is more stable.

By this arrangement, it can be ensured that the extending section 421 of the limiting plate 42 can abut against the extending section during actual use, so that the cantilever 40 can be maintained at the extended position or the retracted position.

Optionally, the clutch assembly 30 includes: the lapping frame 31 comprises a first section, a second section and a third section which are connected in sequence, the second section is arranged on one side of the support frame 10 far away from the first limiting component 20, the first section and the third section are respectively connected with the two support columns 11, the first section and the third section are even and vertical to the second section, and the first section and the third section both extend towards the first limiting component 20; the lap joint plate 32, the lap joint plate 32 respectively with first section, second section, third section perpendicular and constitute between four and enclose the chamber, the side surface that deviates from to enclose the chamber of lap joint plate 32 is as the faying surface, the first end or the second end and the faying surface cooperation of cantilever 40.
