When the construction platform 9 needs to be raised, the construction workers start the motor 4, and the motor 4 drives the stud 5 to rotate through the output shaft. The two slides 6 move in opposite directions in the slide groove 3, so that the support arm 8 on the slide 6 drives the construction platform 9 to rise by rotating, and the construction platform 9 drives the pillar 11 to rise inside the sleeve 10 when it rises, so that the workers can connect the sleeve 10 and the pillar 11 through the pin hole 12 and the pin 13 according to the height of the construction platform 9.
