The lifting platform 2 is slidably connected inside the column 1. The locking structure 6 is disposed on one side wall of the column 1. The locking structure 6 determines its position according to the required stopping height of the lifting platform 2, and can lock the lifting platform 2 at any position within the lower limit or stroke, facilitating movement and stable use. A portion of the locking structure 6 penetrates into the column 1, and the portion of the locking structure 6 penetrating into the column 1 can coincide with the movement trajectory of the lifting platform 2. The locking structure 6 includes a lock head 61, which includes a rotating part 611, a protruding ring 612, and a locking block 615. The rotating part 611 is rotatably connected to one side wall of the column 1 and is used to change the position of the lock head 61 by rotation. The posture enables the switching between unlocked and locked states. One end face of the convex ring 612 is connected to one end of the rotating part 611. The convex ring 612 is used to restrict the axial movement of the lock head 61. The locking block 615 is set on the other end face of the convex ring 612 and extends into the column 1. When the rotating part 611 is rotated, the locking block 615 can engage with the lifting platform 2. The lifting platform 2 stops completely under the action of internal force and the obstruction of the lock head 61. When the end face of the locking block 615 facing the axis of the lock head 61 is parallel to the movement trajectory of the lifting platform 2, the lifting platform 2 can move freely within its stroke range. When the end face of the locking block 615 facing the axis of the lock head 61 rotates to be perpendicular to the movement trajectory of the lifting platform 2, the locking block 615 can lock the lifting platform 2.

The knob cap 63 cooperates with the convex ring 612 to limit the forward and backward movement of the lock head 61. The diameter of the knob cap 63 is greater than that of the extension shaft 614, so that labor can be saved during rotation. An indicating mark is arranged on the outward end face of the knob cap 63. Through the indicating mark, the locking state can be determined. The fixing part 62 is used to improve the stability of the rotation of the lock head 61 and prolong the service life.
