This utility model discloses a telescopic leg tube and support frame with a quick locking and unlocking function. The telescopic leg tube includes a linkage rod and several sequentially cascaded leg tube assemblies. The linkage rod passes through several leg tube assemblies. Each leg tube assembly includes an outer tube, an inner tube, a synchronizing sleeve, a connecting sleeve, and a locking component. The synchronizing sleeve can move axially in a first direction relative to the linkage rod when the linkage rod rotates in the forward direction, thereby driving the locking component through the inner tube to restrict the relative movement between the inner tube and the outer tube of the next-level leg tube assembly. Alternatively, the synchronizing sleeve can move axially in a second direction relative to the linkage rod when the linkage rod rotates in the reverse direction, thereby driving the locking component through the inner tube to release the restriction on the relative movement between the inner tube and the outer tube of the next-level leg tube assembly. Through the above structure, multiple sets of leg tube assemblies can be simultaneously locked and unlocked by the linkage rod, making the structure uniform, which not only improves the convenience of use but also reduces the structural complexity and production cost.
