Further, as shown in fig. 4, two upper and lower third threaded holes 1151 are formed on the opposite surfaces of the two stoppers 115, an adapted screw rod 1152 is mounted in the third threaded hole 1151, a limit plate 1153 is sleeved outside the screw rod 1152, the limit plate 1153 is in a circular ring shape, a symmetrical slide block 1154 is arranged on the inner ring of the limit plate 1153, a third slide groove 1155 adapted to the slide block 1154 is formed on the side wall of the screw rod 1152, a second spring 1156 is arranged between the limit plate 1153 and the stoppers 115, and the second spring 1156 is sleeved on the screw rod 1152; the face of the carrier plate 18 opposite the stop 115 is provided with a blind hole adapted to the threaded rod 1152, the diameter of which is greater than the threaded rod 1152.
Because a gap exists between the carrier plate 18 and the two stop blocks 115, the carrier plate 18 is necessarily contacted with the stop blocks 115 in the sliding rail movement process, the carrier plate 18 is usually of a resin structure, the carrier plate 18 is damaged due to the rigid collision between the carrier plate 18 and the metal stop blocks 115 for a long time, and noise is generated in the collision process; the stop block 115 is designed to add a buffer component, in the sliding process of the slide rail, a blind hole on the carrier plate 18 is matched with the screw rod 1152, when the blind hole is contacted, the head of the screw rod 1152 is inserted into the blind hole, the carrier plate 18 contacts and presses the limit plate 1153, the second spring 1156 plays a buffer role in the pressing process of the carrier plate 18, the rigid collision of the carrier plate 18 and the stop block 115 is avoided, the damage of the carrier plate 18 caused by the collision can be effectively prevented, and meanwhile, the collision noise of the carrier plate 18 and the stop block 115 can be reduced.
Further, as shown in fig. 2, the height of the stop block 115 is smaller than that of the inner clamping portion 111, so that the stop block 115 is prevented from being excessively clamped in the lower sliding rail, and the sliding rail cannot work normally.
Further, the length of the thread on the screw 1152 is the same as the depth of the threaded hole 151, so that the smoothness of the surface of the exposed part of the screw 1152 is ensured, and the sliding of the limiting plate 1153 is facilitated.
