Description

TECHNICAL FIELD The present disclosure relates to the field of supporting equipment, in particular to a support leg stand with support legs capable of fully bouncing off. BACKGROUND The supporting device is often used to hold equipment such as projectors, mobile phones and cameras. Tripod is a common support structure. In order to realize convenient storage, the tripod is often designed as a structure that can be folded and unfolded. For example, a previous application with a patent number of CN201921123317.9 discloses a support stand; when not in use, support legs can be folded to a center column for easy carrying; when it needs to be used, pressing an elastic clamping mechanism can slightly unfold the support legs from a position where they fit with the center column. However, this kind of unfolding only changes the support legs into an unfoldable state, and the unfolding range is very limited. It is still necessary to manually rotate the support legs to fully unfold them. Therefore, it can be further optimized to solve the problem that the support legs need to be rotated manually for fully unfolding them. SUMMARY The main purpose of the present disclosure is to provide a support leg stand with support legs capable of fully bouncing off. Multiple support legs can be unlocked at the same time when being stimulated by an external force, and the multiple support legs are fully unfolded without manually rotating them, and the unfolding is faster and more convenient. In order to achieve the above-mentioned purpose, the present disclosure provides a support leg stand with support legs capable of fully bouncing off, comprising a center column, the center column being provided with a connecting seat;unfoldable/foldable support legs; one end of the support leg is rotatably connected with the connecting seat, and the other end thereof is a free end; when the free end of the support leg is close to the center column, the support leg is folded, and when the free end of the support leg is away from the center column, the support leg is unfolded;a locking assembly, wherein the locking assembly is adapted to fit with the free end of the support leg when the support leg is folded, so as to limit the movement of the support leg relative to the center column, and the locking assembly will release constraint after being triggered; andreinforcing ribs; wherein one end of the reinforcing rib is rotatably connected with the support leg, and the other end thereof is rotatably connected with the center column/locking assembly; in addition, a first elastic member is arranged between the reinforcing rib and the support leg; when a free end of the support leg is adapted to fit with the locking assembly, the first elastic member undergoes elastic deformation and generates a restoring force; when the locking assembly releases constraint, the free end of the support leg moves away from the center column under action of the restoring force of the first elastic member and the support legs fully unfold. In a specific solution, the reinforcing rib is provided with a first rotation axis, the first rotation axis is rotatably connected with the support leg; and the first elastic member is a torsion spring sleeved on the first rotation axis; and when the free end of the support leg is adapted to fit with the locking assembly, the torsion spring is twisted and generates a torsional force; when the locking assembly releases constraint, the torsion force provided by the torsion spring drives the free end of the support leg away from the center column and the support legs then fully unfold. In a specific solution, at least two first grooves are formed on the support leg, and both ends of the first rotation axis are respectively inserted into the first grooves to form a structure in which the first rotation axis rotates in the first groove. In a specific solution, the support leg is further provided with a stop block, the stop block is arranged at an opening of the first groove and configured to prevent the first rotation axis from sliding out of the first groove. In another easily conceivable alternative, a stop block is arranged on the support leg, at least two first grooves are formed on the stop block, and both ends of the first rotation axis are respectively inserted into the first grooves to form a structure in which the first rotation axis rotates in the first groove. In a specific solution, the torsion spring comprises a main body and a first and a second force arms extending from the main body, the main body is sleeved on the first rotation axis, the first force arm abuts against the support leg, and the second force arm abuts against the reinforcing rib. In a specific solution, a first through hole is formed on the support leg, the first force arm passes through or abuts against the first through hole, a second through hole is formed on the reinforcing rib, and the second force arm passes through or abuts against the second through hole.
