In the implementation process, the rotating bracket 700 is formed by splicing an intermediate rod 701, a head piece 702 and a connecting piece 703 and is shaped like a bamboo joint rod. Wherein, a middle rod 701 is connected with the adjustable elastic component 800 in a rotating way, and two ends of the middle rod 701 are respectively connected with the first spherical plug 706 in a threaded way; the two end head pieces 702 are arranged on two sides, one end of each end head piece 702 is smoothly arranged, the other end of each end head piece 702 is provided with a first spherical groove 705, and one end of each connecting piece 703 can penetrate into the first spherical groove 705 to be connected with the connecting piece; after the connectors 703 are fixed in end-to-end relationship, one end of each connector is connected to the intermediate rod 701 and the other end of each connector is connected to the end piece 702. The connectors 703 may be arranged in the number of splices as desired for length.

The rotating bracket 700 not only can rotate around the adjustable elastic member 800, but also can be bent itself and can be fixed after being bent. Can be adjusted according to the requirements of stacked goods.

In some embodiments, a plurality of rotating brackets 700 may be installed on the loading frame 100, the rotating brackets 700 are parallel to the loading frame 100 when being stored and attached to the side of the loading frame 100, and when the rotating brackets 700 are used, they form a certain angle with the loading frame 100, so as to sufficiently fix the stacked goods.

In some embodiments, after the rotating bracket 700 is rotated by a certain angle, a pocket net can be installed on the rotating bracket 700, so that the pocket net is arranged in front, and the opening back is convenient to detach backwards.

It should be noted that, in the present application, the connecting member 703 is composed of a rotating portion 7031, a connecting pipe 7032, and the like, and the connecting pipe 7032 has two open ends, and the two connecting pipes 7032 are symmetrically connected to two sides of the rotating portion 7031 and are rotatably connected thereto.

A connecting tube 7032 is sealed at one end by a rotating portion 7031 and at the other end by a first sealing plug 7033, and a second ball-type plug 7034 is screwed to the first sealing plug 7033.

One end of the other connecting pipe 7032 is sealed by the rotating part 7031, the other end is provided with a second sealing plug 7044 close to the pipe orifice, the pipe orifice is provided with a second spherical groove 7035 fixedly connected with the second sealing plug 7044, and the second spherical groove 7035 can allow the first spherical plug 706 or the second spherical plug 7034 to penetrate for rotating fit, namely, the other connecting piece 703 or the middle rod 701 is butted with the connecting piece 703. A fixed seat 7036 is fixed on the outer ring of the second spherical groove 7035, a locking ring 7037 which sleeves the first spherical plug 706 or the second spherical plug 7034 is arranged on the side edge of the fixed seat 7036, a limiting rod 7038 fixed on the side edge of the locking ring 7037 penetrates through the fixed seat 7036 and the second sealing plug 7044 to enter the connecting pipe 7032, and the first spherical plug 706 or the second spherical plug 7034 can be fixed inside the second spherical groove 7035 by tightening the locking ring 7037 inside the connecting pipe 7032.

A threaded rod 7041 penetrates through the middle of the rotating part 7031, a clamping piece 7042 is installed at one end of the threaded rod 7041, a stopping piece 7043 is fixed at the other end of the threaded rod 7041, the rotating part 7031 can limit the rotation of the threaded rod 7041 by the clamping piece 7042 in the rotating process, and the threaded rod 7041 moves horizontally and reversely. The limit rod 7038 passes through the stop 7043 and is in sliding fit with the stop 7043, and a first elastic element 7039 mounted at the end of the limit rod 7038 is connected with the stop 7043.

In an initial state, under the action of the first elastic element 7039, the locking ring 7037 can enable the first spherical plug 706 or the second spherical plug 7034 to be located inside the second spherical groove 7035, and when an external force is applied to the first spherical plug 706 or the second spherical plug 7034, the first spherical plug 706 or the second spherical plug 7034 can rotate in any reverse direction, so that the rotating bracket 700 can be inclined.
