[0035] The positioning component 30 comprises a limiting post 33 disposed on the positioning plate 31 and disposed opposite to a mounting hole 111, the limiting post 33 comprises a receiving groove 331 for accommodating the first fastener 40, the first fastener 40 is limited within the receiving groove 331 and cooperates with the mounting hole 111. When the positioning component 30 and the sliding member 10 are pre-positioned and assembled through the first positioning structure and the second positioning structure, the first fastener 40 should be accommodated in the receiving groove 331.

[0036] It should be noted that, after the first fastener 40 is pre-installed in the mounting hole 111, the sliding member 10 then cooperates with the positioning component 30, and the limiting post 33 of the positioning component 30 needs to be sleeved on the first fastener 40, so that the receiving groove 331 can limit the screw cap of the first fastener 40.

[0037] The limiting post 33 comprises a stepped portion 332 disposed at an end of the receiving groove 331 away from the mounting hole 111, the stepped portion 332 protrudes inward relative to an inner wall of the receiving groove 331, the stepped portion 332 has a stepped surface 333 facing the mounting hole, a distance from the stepped surface 333 to the mounting hole 111 is not greater than a length of the first fastener 40; the first fastener 40 has a pre-installation state, in the pre-installation state, the screw cap of the first fastener 40 is axially limited at the stepped surface 333, an end of the screw rod is limited at a positioning rib 113.

[0038] Continuing in combination with FIG. 11, when the positioning component 30 and the sliding member 10 are completely assembled, the first fastener 40 is pre-installed in the receiving groove 331 and the mounting hole 111, shaking may occur when the positioning component 30 and the sliding member 10 are further assembled with the second door 310, in order to prevent the first fastener 40 from being affected and generating displacement, the stepped surface 333 is disposed along an axial direction of the first fastener 40, thus, the screw cap of the first fastener 40 is limited by the stepped surface 333 along the axial direction, and the end of the screw rod of the first fastener 40 is also limited by the positioning rib 113 along the axial direction, the first fastener 40 as a whole cannot generate displacement along the axial direction. It should be noted that, the axial direction of the first fastener 40 is also a common axial direction of the screw cap and the screw rod.

[0039] An inner diameter of the receiving groove 331 gradually increases in a direction approaching the mounting hole 111, the first fastener 40 has the pre-installation state, in the pre-installation state, the screw cap of the first fastener 40 is limited in a radial direction thereof at an inner wall surface of the receiving groove 331 adjacent to the stepped surface 333.

If the inner diameter of the inner wall surface of the receiving groove 331 below the stepped surface 333 is too large, then in a case of shaking or vibration, the screw cap of the first fastener 40 may tilt radially. Therefore, setting the inner diameter of the receiving groove 331 adjacent to the stepped surface 333 to be less than or equal to an outer diameter of the screw cap of the first fastener 40 can hold the first fastener 40. Or, the inner diameter of the receiving groove 331 adjacent to the stepped surface 333 is slightly larger than the outer diameter of the screw cap of the first fastener 40 within 3mm, within this deviation range, a radial displacement of the first fastener 40 will not affect a normal installation of the first fastener 40.
