TECHNICAL FIELD The present disclosure relates to the technical field of auxiliary equipment for electronic terminals and other devices, and more specifically to a multi-legged stand. BACKGROUND With the proliferation of mobile imaging technologies such as short video recording, live streaming, and time-lapse photography, multi-legged stands like tripods and quadpods have become essential tools for achieving stable captures. Categorized by imaging equipment type, these stands include models tailored for mobile phones, cameras, and other devices. Contemporary multi-legged stands typically include a support rod assembly, at least three support leg assemblies, etc. Currently, the folding of the support leg assemblies on most stands relies predominantly on snap-fit mechanisms. This design forces users to operate with both hands: one hand must grip structural components like the support rod assembly, while the other manually unfolds each support leg assembly for splaying the support leg assemblies. Consequently, the deployment of the support leg assemblies proves notably inconvenient. The above content serves solely to facilitate understanding of the technical solution of the present disclosure and does not constitute acknowledgment of said content as prior art. SUMMARY OF THE DISCLOSURE The present disclosure provides a multi-legged stand, including: a support rod assembly, a sliding sleeve assembly, a connecting assembly, and at least three support leg assemblies; wherein the support rod assembly extends along a length direction, and the sliding sleeve assembly is slidably sleeved on a periphery of the support rod assembly along the length direction of the support rod assembly; the at least three support leg assemblies are rotatably connected to the sliding sleeve assembly, and the connecting assembly is rotatably connected to the at least three support leg assemblies and the support rod assembly; the connecting assembly is configured to splay or fold the at least three support leg assemblies in conjunction with the sliding sleeve assembly sliding relative to the support rod assembly; in a case where the at least three support leg assemblies are in a folded state relative to the support rod assembly, the at least three support leg assemblies are subjected to a folding force to keep folded relative to the support rod assembly;wherein the multi-legged stand further includes a preliminary opening assembly movably connected to the support rod assembly; the preliminary opening assembly is configured to, in response to being subjected to an external action, overcome the folding force and push open the at least three support leg assemblies, causing the at least three support leg assemblies to transition from the folded state to a preliminarily opened state relative to the support rod assembly.
