When the size of the sub-parts to be positioned and stored is changed and the relative position of the bearing bracket 230 on the bearing plane 110 needs to be adjusted, the pressing plate 332 is pressed downwards along the direction perpendicular to the bearing plane 110, so that the rotating wheel 330 connected with the pressing plate 332 rotates around the pin 320, the limiting teeth 331 protruding along the radial direction of the rotating wheel 330 are driven to leave the teeth on the rack 310, and the meshing between the limiting teeth 331 and the rack 310 is released. The entire carriage 230 and the first slider 220 are then pushed to slide on the first slide rail 210, so as to adjust the position of the carriage 230 according to the size of the sub-part. While the pressing plate 332 is pressed to release the engagement of the catching teeth 331 with the rack 310, the torsion spring 340 having one end connected to the rotation wheel 330 rotates along with the rotation wheel 330 to generate a rotational force. After the supporting frame 230 is adjusted in position, by releasing the pressing of the pressing plate 332, the rotating wheel 330 can rotate reversely to the initial position under the rotating force of the torsion spring 340, so that the limiting teeth 331 are engaged with the rack 310 again, and the first sliding block 220 and the supporting frame 230 are limited and fixed again. The positioning and supporting precision and stability of the sub-parts by the bearing bracket 230 after the position adjustment are ensured.

The staff can correspond according to the sub-part of not unidimensional and adjust two distances that bear between the support 230 among every group auto parts location strorage device, realize locating the storage to the sub-part of car of multiple different grade type to carry through the platform truck and transport, improve the whole production efficiency of the automobile production line at place.
