[0025] In this embodiment, when folding is required, the handle 6 is held and pulled outward, and the handle 6 is pulled to pull the insertion rod 3 and compress the spring 1 4 until the end of the insertion rod 3 is withdrawn from the slots 5 on both sides of the base 1, and then the base 1 1 and the base 2 2 are folded and turned downward. When folding and turning, the two sides of the bottom end of the connection between the base 1 and the base 2 are guided by the hinge until the lower end surfaces of the base 1 1 and the base 2 2 are fitted together, which can reduce the storage space by half, making it more convenient to carry and not taking up too much space.

[0026] like Figure 2 and Figure 3As shown, a locking mechanism is provided in the middle part of the inner part of the base 1, and the locking mechanism includes a threaded sleeve 7, which is movably mounted on the inner side of the middle part of one end of the base 1 away from the base 2, and a knob 8 is fixedly mounted on the other end of the threaded sleeve 7. A threaded rod 9 is internally threadedly connected to one end of the threaded sleeve 7 away from the knob 8, and an inclined block 10 is fixedly mounted on one end of the threaded rod 9 away from the threaded sleeve 7. The locking mechanism also includes an inclined block 11, which is movably mounted on both sides of the base 1 close to the inclined block 10, and an inclined groove 12 is provided on one side of the insertion rod 3 close to the inclined block 11, and one end of the inclined block 11 away from the inclined block 10 matches the inclined groove 12, a spring 13 is provided on the inner wall of one side of the base 1 close to the inclined block 11, and a top block 14 movably connected to the spring 13 is provided on one side of the inclined block 11, and a sliding groove 15 is provided on both sides of the base 1 close to the threaded rod 9, and sliders 16 slidably connected to the sliding groove 15 are provided at both ends of the threaded rod 9 close to the inclined block 10.

[0027] In this embodiment, after the base 1 and the base 2 are assembled, the knob 8 is twisted, and the knob 8 drives the threaded sleeve 7 to rotate.
