In a specific embodiment, the supporting device is in a supporting state (as shown in fig. 1), wherein an end of the first bracket 20 away from the second bracket 30 is fixed to the base 10 to prevent the first bracket 20 from being separated from the base 10, the second bracket 30 is connected to the first bracket 20 by a bolt, and the angle relationship between the two can be changed by adjusting the tightness of the bolt, preferably, the predetermined angle between the second bracket 30 and the first bracket 20 is 95-120 °. When the first bracket 20 and the second bracket 30 need to be accommodated, the tightness of the bolts is adjusted, the second bracket 30 is rotated, so that the second bracket 30 is accommodated in the first bracket 20 (as shown in fig. 2), and then the limiting member on the first bracket 20 is adjusted, so that the first bracket 20 is fixed to the base 10. The invention has simple structure and easy operation, can not only play a good supporting role but also can be well stored in a non-supporting state by adjusting the first bracket 20 and the second bracket 30 to be in a supporting state and a storing state, thereby minimizing the volume, occupying no external space resource, being convenient for storage, transportation and the like and further reducing the cost.

Optionally, the base 10 is a hollow frame, and one or more groups of channels 100 with horizontal components are arranged on an outer frame of the hollow frame; according to the actual situation of supporting the object, one side of the outer frame may be provided with a set of channels 100, or a plurality of sets of channels 100 may be provided on the side, or the channels 100 may be provided on multiple sides of the outer frame, the number of the channels on each side is adjustable, as shown in fig. 1, the channels 100 are provided on two sides of the outer frame in the figure, and the number of the channels on each side is two. One end of the first bracket 20 away from the second bracket 30 is provided with a fixed limiting member 200, and the fixed limiting member 200 protrudes out of the surface of the first bracket 20 to prevent the first bracket 20 from separating from the base 10.

In one embodiment, a fixed limiting member 200 is disposed at an end of the first bracket 20 away from the second bracket 30. The fixing stopper 200 may be a fastening screw protruding from the mounting surface of the first bracket 20, so that when the supporting device is in the supporting state, the fixing stopper 200 can prevent the first bracket 20 from completely passing through the channel 100 and being separated from the base 10. The channel 100 may be horizontally disposed or have a certain inclination, and in this embodiment, it is preferable that the channel 100 is horizontally disposed and extends from the inside of the base 10 to the outside of the base 10. By arranging the fixing limiting part 200, the first support 20 can be well prevented from being separated from the base 10, so that the overall supporting structure is more stable.

Further, the first bracket 20 is further provided with a movable limiting member 201, the movable limiting member 201 has a degree of freedom different from the sliding direction of the first bracket 20, when the adjustable movable limiting member 201 protrudes out of the first bracket, the movable limiting member 201 cooperates with the fixed limiting member 200 to fix the first bracket 20, and when the adjustable movable limiting member 201 does not protrude out of the first bracket 20, the first bracket 20 slides along the channel 100 under the action of an external force.

Similarly, the movable limiting member 201 may also be a fastening screw, except that the depth of the movable limiting member 201 on the first bracket 20 is adjustable. The distance from the movable limiting member 201 to the fixed limiting member 200 is substantially equal to the width of one side of the base 10, i.e. the length of the channel 100. When the supporting device is converted from the storage state to the supporting state, the initial state of the movable limiting member 201 is lower than or equal to the mounting surface, and when the supporting device is completely supported, that is, the fixed limiting member 200 abuts against the base 10, the movable limiting member 201 is adjusted to protrude from the mounting surface, and the first bracket 20 is limited by the fixed limiting member 200.

In this embodiment, by providing the movable limiting part 201, the first bracket 20 in the fully supporting state can be limited and fixed by matching the fixed limiting part 200, so that the overall structure is more stable and the supporting effect is better.

It can be understood that, since the second bracket 30 and the first bracket 20 are rotatably connected by the connecting shaft 202, although the purpose of supporting and accommodating the second bracket can be achieved, the support is unstable, and in order to prevent the relative movement of the two brackets during the support process, the limit fixation is performed by arranging the fastening screw 203; when the second bracket 30 needs to be stored, the fastening screw 203 is loosened along the arc-shaped groove 207. In this embodiment, by providing the fastening screw 203 and the arc-shaped groove 207, the overall stability of the supporting device is improved, and the stable proceeding of the supporting process is ensured.

Further, one end of the first bracket 20 connected to the second bracket 30 is provided with an abutting plate 204 extending in a direction different from the sliding direction of the first bracket 20, and the abutting plate 204 is fixedly connected with a second fastening screw 206 for connecting with the base 10.

Specifically, during the actual storage operation, only one set of racks is generally operated at the same time, i.e., after the second rack 30 in a certain set is received in the first rack 20, the first rack 20 is slid along the channel 100. In the embodiment, in order to prevent the first bracket 20 from being separated from the base 10 due to an excessively large sliding distance when being stored, the abutting plate 204 is provided for limiting, preferably, the abutting plate 204 is perpendicular to the side surface of the first bracket 20, and by providing the second fastening screw 206, the supporting device is more stable in overall structure after being stored, and is convenient to store and transport.

In an embodiment, referring to fig. 4, the third limiting member 101 is rotatably connected to the base 10 to limit or release the limit of the abutting plate 204.

Specifically, after the first bracket 20 is received in the base 10, the third limiting member 101 is adjusted to rotate the rotating piece to a proper position, so that the rotating piece abuts against the abutting plate 204, thereby preventing the first bracket 20 from exiting from the base 10 in the transportation process, ensuring a more firm receiving state and more convenient storage and transportation.

Further, one end of the first bracket 20 close to the second bracket 30 is provided with a holding part 205, and the holding part 205 is arranged, so that the supporting and accommodating processes of the first bracket are more convenient and labor-saving.

Optionally, the support bracket is disposed on one or more sides of the base 10.

Specifically, in the actual use process, an appropriate supporting scheme can be selected according to the characteristics of the supporting object, for example, when the center of gravity of the supporting object is deviated to a certain side, only one or more sets of the first support 20 and the second support 30 need to be arranged on the side, the supporting is completed by matching with the caster 40 and the foot rest 50, and the number of the first support 20 and the second support 30 is determined by the weight of the supporting object. When the mass distribution of the supporting object is uniform, the supporting object can be arranged on two sides, and the most stable supporting state is kept. When the supporting object is too heavy, the first and

second cradles

20 and 30 may be provided on four sides. In the embodiment, various combination schemes can be selected according to the supporting object, and the device is flexible to use, simple to operate, stable and reliable.
