The shorter the distance is, as shown in the seventh figure. If the position of the rod 432a of the adjusting rod 432 is locked into the first positioning hole 412, the position of the head 432b of the adjusting rod 432 is farther away from the sliding seat 41, and the positioning block 42 is pushed away by the first elastic member 431. The longer the distance, as shown in the eighth picture. The two second elastic members 51 are stretched to a certain length to have an elastic force for pulling the slider 41 back. When the drawer is pushed inward to a certain distance, the inner slider 23 is pushed The block 231 hits the slope 421 of the positioning block 42 to gradually displace the positioning block 42 in the direction of the slider 41 and compress the first elastic member 431 (not shown). After the drawer is further moved to a depth in the interior of the cabinet, the push block 231 of the inner slide rail 23 enters the buckle groove 426 of the positioning block 42 so that the convex portion 424 of the positioning block 42 is separated from the card slot 322. The long hole 321 is in the middle. The drawer continues to move toward the cabinet. The positioning block 42 pushes against the protrusion 411 of the sliding seat 41, so that the positioning block 42 and the sliding seat 41 are along the track 32 of the base toward the base. The direction of the holder 31 is moved until the slider is displaced to a second position, as shown in the sixth figure. When the slider is in the second position, the drawer is completely moved into the cabinet and the two second elastic members 51 are compressed.

The gap between the drawers of different sizes and the cabinet is different, that is, installed in The inner slide rails of different sizes have different gaps from the slide rails installed outside the cabinet. The distance between the positioning block 42 and the first elastic member 431 can be determined by adjusting the depth of the rod 432a of the adjusting rod 432 to the first positioning hole 412. In use, the first elastic member 431 can automatically finely adjust the distance between the positioning block 42 and the sliding seat 41 to correspond to the inner and outer sliding rails of different gaps, so that the present invention is applicable to drawers and cabinets with different gaps. Between the bodies. First, as shown in the seventh figure, the drawer slide of the present invention is installed between the drawer with a small gap and the cabinet, and the first elastic member 431 pushes the positioning block 42 to a small extent to make the inner slide rail. The push block 231 of 23 is able to touch and push the positioning block 42 during the movement. Referring to FIG. 8 again, the drawer slide of the present invention is installed between the drawer with a large gap and the cabinet, and the first elastic member 431 pushes the positioning block 42 substantially to make the inner slide rail. The push block 231 of 23 is able to touch and push the positioning block 42 during the movement.

It is worth mentioning that the bevel 421 of the positioning block 42 is designed to contribute to the inner slider. The push block 231 of 23 smoothly shifts the positioning block 42 toward the slider 41 and compresses the first bullet The feature 431 achieves the effect of fine-tuning the distance between the slider 41 and the positioning block 42.

In addition, the outer diameter of the head 432b of the adjusting rod 432 is larger than the second positioning hole 423. Thereby, when the first elastic member 431 finely adjusts the distance between the sliding seat 41 and the positioning block 42, the positioning block 42 is The distance of the outward movement is limited by the head 432b of the adjustment lever 432, so that it is not pushed out by the first elastic member 431.

Moreover, the head 432b of the adjusting rod 432 forms the lateral groove 432b1, and the user can easily adjust the rod 432a of the adjusting rod 432 by rotating the head 432b of the adjusting rod 432 by using a tool such as a flat-blade screwdriver. The screw is disposed at a depth of the first positioning hole 412.
