When the plane rod 100 is opened, the two support rods 111 are driven to be in a collinear state, and finally, the two ends of the plane rod 100 are far away from each other, the two support rods 111 on the same side are kept in a collinear state, so that a support surface is formed, an object can be placed on the support surface, and the support legs 112 can support the object.

Referring to fig. 3, in the present embodiment, in order to improve the strength of the support, a reinforcing rod 120 is installed at the lower side of the plane rod 100, the middle portions of the two reinforcing rods 120 are hinged to each other, the hinge point of the two reinforcing rods 120 coincides with the plane rod 100 in the vertical projection, the plane rod 100 is hinged by a connecting member 121, the connecting member 121 includes a connecting sleeve 122 and a fixing screw 123 which are inserted into the plane rod 100, the fixing screw 123 is screwed into the connecting sleeve 122 and is embedded into the upper plane rod 100, and a protruding ring 124 which separates the plane rod 100 from the reinforcing rod 120 is further provided at the lower side of the connecting sleeve 122, and when the fixing screw 123 is screwed, the two plane rods 100 are limited by the upper ends of the fixing screw 123 and the protruding ring 124. The lower side of the convex ring 124 is also integrally provided with a connecting pipe 125 penetrating through the two reinforcing rods 120, and a connecting frame such as a telescopic rod can be further connected to the middle of the connecting pipe 125, so that the whole bracket can be applied to a tripod. Meanwhile, both ends of the reinforcing rod 120 are provided with upwarping portions 126 fixedly connected with the lower side of the plane rod 100, and the convex ring 124 and the upwarping portions 126 enable a gap to be formed between the plane rod 100 and the reinforcing rod 120, so that the reinforcing rod 120 has a reinforcing function.

Referring to fig. 2 and 3, the two ends of the supporting rod 111 have protrusions 113 that are symmetrical with respect to the geometric center of the supporting rod 111, the protrusions 113 are disposed to be inclined toward the side away from the ends of the supporting rod 111, and when the two supporting rods 111 are collinear, the protrusions 113 on the ends of the two supporting rods 111 that are close to each other are both away from the hinge point of the two plane rods 100. The raised parts 113 at the opposite ends of the two support rods 111 are provided with grooves and tongues which can be lapped together. When the bracket is opened, the protrusion 113 will abut against the grooved step, so that the two support bars 111 can be kept in a collinear state.

Referring to fig. 4, the bracket is in a state of being completely collapsed.

The implementation principle of the embodiment is as follows: when it is desired to open the bracket, the support rods 111 on both sides are far away from each other, and the two ends of the plane rod 100 are far away from each other, so that the support rods 111 are finally kept collinear, and the entire bracket is opened to form a support surface on which an object can be placed and supported by the support feet 112. The bracket can also be integrally mounted on the tripod.

Embodiment 2 is different from embodiment 1 in that, referring to fig. 5 and 6, the relative rotation directions of the two support rods 111 are reversed by the adjusting member 130. The adjusting member 130 includes an insertion block 131 and a limit tooth 132, the insertion block 131 is slidably connected to one of the protrusions 113 in a direction parallel to the rotation axis of the plane rod 100, and the limit tooth 132 is integrally disposed on the upper side of the other protrusion 113 in the circumferential direction. Meanwhile, an accommodating ring groove 133 for embedding the limiting convex tooth 132 is formed in the lower side of the protruding portion 113 provided with the insertion block 131, and the insertion block 131 slides and is embedded into the accommodating ring groove 133.

Referring to fig. 7 and 8, the supporting rod 111 is provided with an elastic member for driving the insertion block 131 to be inserted between the limiting convex teeth 132, in this embodiment, the elastic member is a spring 134, the insertion block 131 is provided with a round rod 135 penetrating through the protruding portion 113, the spring 134 is sleeved on the round rod 135, one end of the spring 134 is fixedly connected with the round rod 135, and the insertion block 131 is provided with an inclined surface abutting against the limiting convex teeth 132. When the two supporting rods 111 rotate relatively, that is, when the bracket is opened, the inclined plane will abut against the limiting convex teeth 132, and at this time, the circular rod 135 will be driven to slide in the protruding portion 113, and the spring 134 will deform continuously, so that the insertion block 131 is embedded between the two adjacent limiting convex teeth 132, and because the other side of the insertion block 131 is a plane, when the bracket has a closed state, the insertion block 131 will abut against the limiting convex teeth 132, so that the bracket can keep a half-opened state.

When the supporting rod 111 needs to be folded, the round rod 135 needs to be lifted up, and after the round rod is rotated by 180 degrees, the inserting block 131 is embedded again, and then the round rod can be reversely rotated. In order to facilitate rotation, a limiting block 136 embedded in the protruding portion 113 is further disposed at one end of the round rod 135, which is away from the insertion block 131, the cross section of the limiting block 136 is rectangular, one end of the spring 134, which is away from the insertion block 131, abuts against the limiting block 136, and a lifting block 137 is further integrally disposed on one side of the limiting block 136, which is away from the round rod 135.

Referring to fig. 9, in order to fit the bracket in the half-open state, the supporting leg 112 is rotatably connected to the supporting bar 111 through a rotating shaft in this embodiment, and in order to maintain the rotation angle, the rotation of the supporting leg 112 is in interference fit with the rotating shaft, so that the supporting leg 112 can maintain the rotation angle after rotating.

And in order to facilitate the opening of the bracket, the two support rods 111 are provided with a buckle slot 114 on the side close to the hinge of the plane rod 100. The user can open the planar pole 100 by placing a finger in the slot 114 and then after the support poles 111 are opened out of alignment, the protrusions 113 face outward, reducing the likelihood of the bracket collapsing and also reducing the likelihood of the hand being pinched when collapsing is desired.

The implementation principle of the embodiment is as follows: when some smaller objects need to be placed on the bracket, the supporting rods 111 are not moved to the collinear state after being opened, at this time, the insertion block 131 can keep the two supporting rods 111 not to rotate reversely, and the supporting feet 112 are rotated to keep the two supporting feet 112 parallel, at this time, the small objects can be placed on the bracket. When wanting to draw in, mention round bar 135 for stopper 136 breaks away from bellying 113, rotate 180 backs, make stopper 136 imbed again in the bellying 113, the inclined plane switching-over this moment can draw in the bracket in, and when drawing in the back, the plane one side of grafting piece 131 will be contradicted on spacing dogtooth 132, improves the firmness after drawing in.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
