This Embodiment 2 is only a preferred embodiment of Embodiment 1, and the implementation of Embodiment 2 will not affect the independent implementation of Embodiment 1. The second Embodiment 2 of the present invention will be further described below.

[0058] Please refer to Fig.15 and Fig.16 As shown, the fixing assembly also includes multiple groups of supporting feet 417, which are respectively fixedly connected to one side of the multiple groups of unfolding plates 406, and are made of wear-resistant rubber material, which can effectively enhance the stability of the device on uneven ground; at the same time, the inner walls of the multiple groups of accommodating grooves 407 are also correspondingly provided with storage grooves 416 for storing these unfolding plates 406, and the top of the storage grooves 416 and one side of the unfolding plates 406 are provided with fourth rotating seats 419, and the two groups of fourth rotating seats 419 are respectively installed with connecting members 420, and a third electric telescopic rod 421 is provided between the two groups of connecting members 420; not only can the unfolding plates 406 be flexibly folded, but also the inclination angle of the unfolding plates 406 can be controlled by telescopic adjustment of the third electric telescopic rod 421, thereby further enhancing the fitting effect and stability of the device in different surface environments, whether it is a flat desktop or a slightly uneven ground, the user can adjust the angle of the unfolding plate 406 to ensure that the device can fit firmly and play the best supporting effect.

[0059] Compared with the method of using the vacuum generator 410 and the suction cups 412 installed on the multiple groups of unfolding plates 406 for adsorption and fixation in the first embodiment, the second embodiment cancels the setting of the vacuum generator 410, and replaces the suction cups 412 of the multiple groups of unfolding plates 406 with support feet 417, and automatically folds or opens the multiple groups of unfolding plates 406 through the third electric telescopic rod 421 to fix the device; the main difference is that a simpler and more direct fixing method can be provided. In actual application scenarios, there is no need to rely on the operation process of the vacuum generator 410, and the stable placement of the device can be quickly achieved directly through the support feet 417, which can not only meet the fixing requirements in different terrains and use environments, for example, on a relatively rough ground or a material surface that is not suitable for adsorption and fixation, the support feet 417 can still provide reliable stability; and the expansion plate 406 can be quickly folded and opened by the extension of the third electric telescopic rod 421, thereby improving the operation convenience and use efficiency of the device; in teaching scenarios where the device position needs to be frequently moved and adjusted, this convenient folding and opening function can save more time.

[0060] Therefore, compared with the adsorption fixing method of setting a vacuum generator 410 and multiple groups of suction cups 412, fixing through multiple groups of support legs 417 can be more adaptable to diverse usage environments and reduce dependence on specific conditions; whether on a flat indoor floor or an uneven outdoor venue, the support legs 417 can play a stable fixing role, thereby providing more reliable and convenient equipment support for teaching activities, allowing teachers and students to focus more on the English teaching and learning process without having to worry about the problem of equipment fixing; the remaining conditions are consistent with Example 1, so this example will not be repeated.

[0061] The embodiments described above are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be included in the protection scope of the present invention.
