Mounting structure of stroke control assembly of lifting stand column

The utility model discloses an installation structure of a lifting stand column stroke control assembly, which is characterized in that at least one long-strip-shaped guide rail is fixed on the outer circumference of a round supporting pipe, an upper limit stroke positioning block and a lower limit stroke positioning block are both installed on the long-strip-shaped guide rail, and a stroke control seat fixed on the inner wall of a lifting pipe is in sliding fit with the long-strip-shaped guide rail. A contact block of the upper limit stroke positioning block, a contact of a stroke switch of the stroke control seat and a contact block of the lower limit stroke positioning block are all on the same straight line; circumferential limiting structures are arranged on the long-strip-shaped guide rails and the bottom end plate; the two long-strip-shaped guide rails are symmetrically distributed on the outer circumference of the circular supporting pipe. The contact block of the upper limit stroke positioning block,
