In this embodiment, due to the above structure, when the bottom plate 2001 and the top plate 2003 are prevented, the pull rod 903 is pulled to the outside of the hollow pressing plate 7, the second slide 902 is driven to move in the first slide 901, the third slide 906 is driven to move in the second slide 905, the fourth slide 908 is simultaneously moved in the oblique moving groove 907 in a direction away from the limiting plate set 8, the first spring 904 is pressed to shorten the storage elastic potential energy, the bottom plate 2001 and the top plate 2003 are placed on the top of the hollow pressing plate 7, and after the adjacent surfaces of the same diagonal angle are respectively abutted with the limiting plate set 8, the pull rod 903 is released, the first spring 904 which is out of the restriction of external force releases the elastic potential energy to enable the second slide 902 to move in the first slide 901 towards the limiting plate set 8, meanwhile, through the cooperation of the balance groove 911 and the fifth slide 909, one slide 906 is driven to move in the direction of the limiting plate set 8 in the corresponding slide groove 901, and the other three slide 906 is abutted with one side wall 906 of the bottom plate 2001 and one side wall of the top plate 2003, and the other three slide 906 slides in the corresponding slide groove 911 under the cooperation of the balance groove 911, the fifth slide 909 and the second slide 906 are pressed close to the limit plate set 8, until the pair of slide 2001 and the adjacent side wall of the three slide 906 are respectively pressed against the other slide 2001 and the other side wall 906 is tightly pressed against the other side wall 906, and the side wall 906 is tightly pressed by the pair of the side of slide 906 and the side 906 through the pair of slide 2001, and the adjacent side of the pair of slide 906 and the side is tightly pressed against the side wall 906 and the side plate 906 through the pair of the side two slide and the side of slide 906 and the side of the slide 906.
Example 10:
in this embodiment, in addition to including the structural features of the foregoing embodiments, it is preferable that:
the first slider 802, the fixed edge 805 and/or the third slider 906 each comprise an upper portion 12 and a lower portion 13 and are each provided with a second spring 11.
In this embodiment, since the above-described structure is adopted, by dividing the first slider 802, the fixing edge 805, and/or the third slider 906 into the upper portion 12 and the lower portion 13 and elastically connecting them by the second spring 11, when the bottom plate 2001 and the top plate 2003 are thin, the first slider 802, the fixing edge 805, and/or the third slider 906 can be adaptively shortened to avoid being crushed when the upper platen 4 and the hollow lower platen 7 press the bottom plate 2001 and the top plate 2003.
It should be noted that, in this document, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element. Furthermore, it should be noted that the scope of the methods and apparatus in the embodiments of the present application is not limited to performing the functions in the order shown or discussed, but may also include performing the functions in a substantially simultaneous manner or in an opposite order depending on the functions involved, e.g., the described methods may be performed in an order different from that described, and various steps may be added, omitted, or combined. Additionally, features described with reference to certain examples may be combined in other examples.
The embodiments of the present application have been described above with reference to the accompanying drawings, but the present application is not limited to the above-described embodiments, which are merely illustrative and not restrictive, and many forms may be made by those having ordinary skill in the art without departing from the spirit of the present application and the scope of the claims, which are to be protected by the present application.
