[0003] At present, the drawer of various office desks is all installed with the drawer guide rail that slides freely. In order to make the drawer close to the office desk after closing, it looks neat and beautiful. The method of the prior art is to use the self-closing angle type guide rail that is internationally used, a section of downward slightly inclined guide rail is arranged at the rear end of the fixed rail, the front roller of the sliding rail installed on the drawer is made to slide downward automatically under the action of gravity when walking to the inclined section, thereby ensuring that the drawer is completely closed. However, this self-closing angle type guide rail has the following disadvantages:

[0004] If the spring elastic force used is insufficient, it is easy to cause the drawer to be unable to close in place;

[0005] If the spring elastic force used is too large, when the overall weight of the cabinet is light, it is easy to cause the drawer to drive the overall cabinet to move when opening, while the drawer is still not completely opened;

[0006] When the drawer is slightly inclined outward, the drawer has the risk of sliding out and falling to the ground;

[0007] Since the drawer has no self-locking function, when moving the table, the drawer is easy to slide out under the action of gravity, causing inconvenience in moving.
