The sliding strip wraps the inner part of the sliding rail extending out of the fixed rail, so that the sliding rail slides smoothly, and the arc salient points reduce friction among the sliding strip, the sliding rail and the fixed rail.

Furthermore, a ball hole is formed in the second sliding strip, a steel ball is arranged in the ball hole, the part of the steel ball protruding out of the second sliding strip forms the arc salient point, the upper part of the steel ball is abutted against the second horizontal part, and the lower part of the steel ball is abutted against the bottom wall of the fixed rail. The second sliding strip is used as a main stress part and is stressed through the steel balls, so that the friction force is reduced, the second sliding strip is not stressed, and the rolling friction between the sliding rail and the fixed rail is easier and more labor-saving.

Furthermore, the top surface of the first horizontal part is provided with a screw hole and a positioning bulge, after the positioning bulge is positioned with the drawer, the drawer is connected with the first horizontal part through a screw passing through the screw hole, and the drawer and the first horizontal part are easy to fix.

Furthermore, the left side of the fixed rail, which is close to the outer end of the fixed rail, is inwards concave to form a limiting bulge, the limiting bulge and the sliding rail move towards the outer end of the fixed rail, and the limiting bulge prevents the sliding rail from being separated from the outer end of the fixed rail.

The beneficial effects of the utility model are as follows.

(1) The sliding rail only comprises the fixed rail, the sliding rail and the sliding strip, the structure is simple, the number of installation parts is small, the assembly is easy, the production efficiency is high, and in addition, one part of the sliding rail is arranged in the fixed rail, so that the whole height of the sliding rail is reduced, and the size is reduced.

(2) Secondly, first stopper restriction slip rail breaks away from the stationary rail inner to restriction slip rail inward displacement, the position piece and the first stopper collision of plastics, the noise that produces is little, and second stopper and first stopper are not fragile, and the fluting has avoided second stopper and first stopper to stagger each other because of colliding the number of times, and spacing protect function is longe-lived, and the arch prevents that the slip rail from deviating from the stationary rail outer end.

(3) And the second sliding strip is taken as a main stress part and is stressed through a steel ball, the second sliding strip is not stressed, the friction force is reduced, and the rolling friction between the sliding rail and the fixed rail is easier and more labor-saving.

(4) In addition, after the positioning protrusion and the drawer are positioned, the drawer is connected with the first horizontal part through a screw penetrating through the screw hole, and the drawer and the first horizontal part are easy to fix.
