Described draw runner surface evenly offers through hole, is provided with ball in the through hole.
The strip groove that described pearl groove is an opening, the sidewall of groove evenly offers through hole, is provided with ball in the through hole.
Described self-locking device comprises slide, slide block, spring, guide rod and the self-locking block that is fixed on interior flange of rail portion, and the slide dual-side offers chute respectively, and slide block constitutes by transverse slat with two slide bars, and slide bar is the one moulding with transverse slat, and slide bar one end is provided with baffle plate; Be provided with spring and guide rod in the chute, two slide bars of slide block embed respectively in two chutes, and spring one end contacts with the baffle plate of slide bar, and guide rod one end passes spring and baffle plate, and the other end is fixed on the slide by rivet; Slide central authorities offer guide groove, and guide groove one end is provided with and colludes groove, and the transverse slat central authorities of slide block are provided with stopper slot, fuse with slide block in the stopper slot of self-locking block one end embedding transverse slat, and the other end embeds in the guide groove of slide.
After adopting said structure, between outer rail and the middle rail, be rolling friction between middle rail and the interior rail, can reduce between each mechanism frictional force, in addition, in the inside groove of outer rail one end, be provided with self-locking device, interior rail one end can be locked in the self-locking device, and rail broke away from self-locking device in rail can make in enforcing, and is convenient and practical.
