When the rotating member 27 and the rotating plate 32 are rotated and then moved downwards to be reset by the second lifting driving mechanism, as shown in fig. 12, the protrusion 25 is located right below the rotating member 27, and at this time, the lower side surface of the rotating member 27 does not exactly correspond to the left side surface of the protrusion 25, as shown in fig. 13, after the rotating member 27 continues to move downwards, one side surface of the rotating member 27 is finally contacted with the protrusion 25, and after the lower side surface of the rotating member 27 is contacted with the protrusion 25, a component force moving towards the right side is provided to the protrusion 25, and finally the frame 23 is moved towards the right side, and at this time, after the rotating member 27 moves upwards again, the protrusion rod 28 located at the upper side can also be contacted with the upper side wall body of the frame 23, and the above-mentioned rotating process for rotating the rotating member 27 and the rotating plate 32 can be repeated.

Furthermore, the slide rail 21 is fixedly connected with a limiting blocking piece 22 for limiting the slide sleeve 24, so that the slide sleeve 21 is limited to be separated from the slide rail 21, and the position limitation of the left and right movement of the frame body 23 is finally realized.

Specifically, the second lifting drive mechanism is including installing third motor 34 and third reduction gear 33 on the platform 20 that slides, the output of third motor 34 with the input fixed connection of third reduction gear 33, the output and the lead screw 30 fixed connection of third reduction gear 33, slide on the platform 20 fixedly connected with lead screw 30 parallel arrangement's guide bar 31, lead screw 30 with guide bar 31 all passes elevating platform 26 and lead screw 30 and elevating platform 26 threaded connection.

In the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
