Therefore, when the limiting ring 65 is located at different positions of the screw 50, the displacement stroke of the positioning piece 60 can be adjusted.

The above structure is the main configuration of the positioning mechanism of the present invention. Since the positioning mechanism is formed into the end sleeve of the roller blind, the present invention further includes the following components: a hollow cylinder 70 is sleeved on the outer circumference of the main body 30 to be rotatable relative to the main body. The outer end of the cylinder 70 is blocked by the shoulder 36 of the main body, and the inner end is blocked by the elastic clasp 37 of the main body so that the cylinder and the main body are not separated from each other.

A shaft member 80 is a hollow cylindrical body, and an outer peripheral surface thereof is provided with a rib 82 along a longitudinal direction thereof. The shaft member 80 is threaded through the main body 30, and the rod 40 is inserted through the sleeve 40. The sleeve rib 82 is engaged with the groove 34 of the main body 30, as shown in the sixth figure. Therefore, the shaft member 80 can only slide along the longitudinal direction of the main body 30. But can't turn. Further, in the present embodiment, the outer end 81 of the shaft member 80 is formed as a connecting hole 84, such as a perforated hole or a polygonal hole.
