Compared with a lead screw, the utility model provides a stroke adjustment mechanism, the cross sectional dimension of its winding 121 is less, and rolling structure 122 rotates the round, also can make position piece 130 remove bigger distance, consequently, the utility model provides a stroke adjustment mechanism saves time more during the adjustment stroke laborsaving, facilitates the use.
