Of course, in other embodiments, the number of the vertical support bars 1323 and the horizontal support bars 1324 may be other values, for example, another vertical support bar 1323 may be disposed between the two vertical support bars 1323, which may further play a role in fixing and guiding the movement of the supporting plate 1311. In a simpler case, the number of the vertical support rods 1323 and the horizontal support rods 1324 may be one, and the supporting plate 1311 may be fixed and guided.

Further, during use, the fixing device 10 needs to be fixed, for example, when the mechanism to be fixed is a broadcasting device, the fixing device 10 needs to be fixed at a position such as a seat (referred to as an external fixing portion) inside an automobile. The present embodiment may be fixedly coupled to the external fixing part through the vertical support 1323 and the horizontal support 1324. Referring to fig. 5, at least one through hole 1320 for connecting with an external fixing portion is formed through the vertical support rod 1323, at least one through hole 1320 for connecting with an external fixing portion is also formed through the horizontal support rod 1324, and the vertical support rod 1323 and the horizontal support rod 1324 are fixed to the external fixing portion by a fixing rope passing through the through hole 1320. The shape of the through hole 1320 may be selected as needed, and is preferably circular, but may be square, for example. When the through hole 1320 has a circular shape, the diameter of the through hole 1320 may be set as required, for example, 4mm, so as to facilitate the fixing rope to pass through. In other embodiments, the external fixing portion may be fixedly connected only by the vertical support bar 1323 or the horizontal support bar 1324.

The number of the through holes 1320 may also be set according to the requirement, for example, the number of the through holes 1320 on the vertical support rod 1323 may be one, and at this time, the through holes 1320 may be opened in the middle of the vertical support rod 1323; the number of the through holes 1320 on the vertical support rod 1323 may be two, and at this time, the through holes 1320 may be opened at two ends of the vertical support rod 1323; the number of the through holes 1320 on the vertical support rod 1323 may be three, and at this time, one through hole 1320 may be opened in the middle of the vertical support rod 1323, and the other two through holes 1320 may be opened at both ends of the vertical support rod 1323. Similarly, the number of the through holes 1320 on the horizontal support rod 1324 may also be one, and the through holes 1320 may be opened in the middle of the horizontal support rod 1324; the number of the through holes 1320 on the horizontal support bar 1324 may be two, and the through holes 1320 may be opened at both ends of the horizontal support bar 1324. It should be understood that the number of the through holes 1320 on the vertical support 1323 and the horizontal support 1324 can also be other values, and is not limited to the above situation, and is not limited herein.
