It should be noted that, the cylindrical hole section described in this embodiment is a cylindrical shape, i.e., a standard cylindrical section. Alternatively, the cylindrical hole section may be approximately cylindrical, since the moving track of the sliding door is not straight but has a very slight inclination angle as described above, so that the cylindrical hole section may be set to be approximately cylindrical, and the cylindrical section 12a may be a standard cylindrical section, in order to avoid possible slight interference of movement, and the radial dimension from left to right may slightly increase, having a very slight taper, for example, about 0.2 degrees, with the view angle of fig. 5.

In addition, as shown in fig. 5, the hole portion of the concave hole 21 facing the convex portion 1 is divided into a conical hole section, and the conical hole section is gradually reduced towards the cylindrical hole section, so that the guide pin 12 can be conveniently inserted into the concave hole 21 and enter the cylindrical hole section through the conical hole section.

Thus, even if the convex part 1 and the concave part 2 are displaced along the X direction, the Y-direction and Z-direction limit is still reliable because the cylindrical section 12a is inserted into the cylindrical hole section for a certain distance. In the background art, the conical pin 01 and the conical concave hole component 02 are matched in an inclined plane, and are slightly loosened along the X direction, so that the Y direction is rocked, and the door is not closed tightly, so that the scheme of the background art needs to be abutted by spring force along the X direction, and once the spring 03 fails, the limiting effect of the sliding door is difficult to guarantee.
