[0005] Further, the movable platform has an upper triangular seat and a lower triangular seat, and both the upper triangular seat and the lower triangular seat are provided with recessed grooves, and an activity chamber is formed inside the movable platform through the two recessed grooves.

[0006] Further, a plurality of screw holes are arranged on the edge of the upper triangular seat, a plurality of studs are arranged on the edge of the lower triangular seat, the studs are inserted into the screw holes and are screwed and connected by screws to complete the connection between the upper triangular seat and the lower triangular seat.

[0007] Further, a rubber pad is arranged on the surface of the upper triangular seat, and the rubber pad fits on the surface of the upper triangular seat to hide the screws and make it look more beautiful.

[0008] The beneficial effects of the present utility model compared with the prior art are as follows: When the support foot assembly of the support body needs to be unfolded and used outward, the unfolding spring pushes the resilient block downward, and the resilient block presses down the top edges of the main support foot, the first auxiliary support foot, and the second auxiliary support foot, so that the bottoms of all of them maintain a tendency to expand outward. Thus, the support foot assembly can be quickly unfolded by the elastic force of the unfolding spring, with a simple structure and convenient operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] As Figures 1 to 5 described, a rapid unfolding structure of a support includes a support body 10, and the support body 10 includes a movable platform 20 and a support foot assembly 30. The top end of the support foot assembly 30 is arranged in the movable platform 20 and is movably hinged to the edge thereof. The support foot assembly 30 includes a main support foot 31, a first auxiliary support foot 32, and a second auxiliary support foot 33. The first auxiliary support foot 32 and the second auxiliary support foot 33 are respectively arranged on the left and right sides of the main support foot 31.

[0016] The movable platform 20 has an upper triangular seat 21 and a lower triangular seat 22. Both the upper triangular seat 21 and the lower triangular seat 22 are provided with recessed grooves. The movable platform 20 forms a movable chamber 201 through the two recessed grooves. A resilient block 51 and an unfolding spring 52 are arranged in the movable chamber 201. One end of the unfolding spring 52 abuts against the inner wall of the upper triangular seat 21, and the other end abuts against the upper surface of the resilient block 51. The edge of the lower surface of the resilient block 51 presses down the top edges of the main support foot 31, the first auxiliary support foot 32, and the second auxiliary support foot 33, so that the bottoms of all of them maintain a tendency to expand outward.

[0017] When the support foot assembly 30 of the support bracket main body 10 needs to be unfolded and used outward, the unfolding spring 52 pushes the spring return block 51 to move downward, and the spring return block 51 presses down the top edges of the main support foot 31, the first sub-support foot 32 and the second sub-support foot 33, so that the bottoms of them all maintain a tendency to expand outward, so that the support foot assembly 30 can be quickly unfolded by the elastic force of the unfolding spring 52.

[0018] A number of screw holes are provided at the edge of the upper triangular seat 21, and a number of studs are provided at the edge of the lower triangular seat 22. The studs are inserted into the screw holes and are screwed and connected by screws 23 to complete the connection between the upper triangular seat 21 and the lower triangular seat 22.

[0019] A rubber pad 12 is provided on the surface of the upper triangular seat 21. The rubber pad 12 fits on the surface of the upper triangular seat 21 to hide the screws 23 and make it look more beautiful.

[0020] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
