To this end, the present invention provides a lateral stopping mechanism 6 for a tray, please refer to fig. 2-4 together, which includes: a support 61 fixedly arranged, wherein the support 61 can be installed on the body part 1 by welding or the like, and is provided with a through hole 611; a stopper beam 62; the driving beam assembly 63 is in transmission connection with the stop beam 62; in the blocking state, the blocking beam 62 can extend through the hole 611 to form a lateral stop for the bracket 4, and in the unblocking state, the driving beam assembly 63 can drive the blocking beam 62 to retract to release the stop for the bracket 4.

With the structure, in the stopping state, the stopping beam 62 can extend out from the through hole 611 to form a transverse stopping for the support part 4, so that the accurate resetting of the support part 4 can be ensured; in the unlocked state, the driving beam assembly 63 can act on the stopper beam 62 to retract the stopper beam, so that the stopper of the holder 4 can be released without affecting the normal separation of the holder 4 and the main body 1.

Further, an elastic member 64 may be further included, and the elastic member 64 may act on the stopper beam 62, and the amount of deformation of the elastic member 64 may be increased during the stopper releasing process to gather the elastic force.

In the drawings, the strip guide hole 631a-1 may be formed at the connection end 6312, and the second hinge shaft 634 may be fixed to the second link beam 632, so that the second link beam 632 may be relatively small in size and compact in structure.

The first anti-loosening element 624 may be a lock nut, or may be an anti-loosening limiting element in the form of a slip, a stopper, or the like.

Further, a connecting plate 613 and a guard plate 614 may be further included, one end of the connecting plate 613 may be connected to the support 61, and the other end may be connected to the guard plate 614 for protecting the driving beam assembly 63, and the aforementioned first hinge shaft 633 may be mounted on the connecting plate 613, and a specific mounting manner may be welding, or may be mounted by means of a mounting plate 633a and a bolt, as long as reliable fixing of the first hinge shaft 633 can be ensured.

With this arrangement, the rotational movement of the connecting end portion 6312 can be converted into the linear movement of the stopper beam 62 by the engagement of the stopper beam 62 with the strip-shaped guide groove 631e, so that the stopper beam 62 is driven to perform the unlocking or the returning of the stopper.

In detail, the connecting end 6312 may be defined between the locker 631f and the retaining member 65, the pre-compression amount of the elastic member 64 may be adjusted by the installation position of the locker 631f on the stopper beam 62, and a spacer 631g may be further provided between the locker 631f and the connecting end 6312 to reduce the abrasion at the connection therebetween.

The "inner side" here means a side close to the main body 1, and with this design, the length of the roller 631d protruding from the inner side can be made short, and contact friction with the main body 1 when the driving end 6311 rotates can be avoided to a large extent.

In the above solutions, the restoring stopping of the stopping beam 62 mainly depends on the elastic member 64 directly acting with the stopping beam 62, and in fact, besides this solution, the driving beam assembly 63 can also drive the stopping beam 62 to restore the stopping state, that is, both the releasing stopping and the restoring stopping of the stopping beam 62 can be completed by the driving beam assembly 63, and this solution can be realized by providing the elastic member to the driving beam assembly 63.
