The branch end 403 is cylindrical. During the above-mentioned movement process, the movement of the slider 503 of the guide frame 502 along the slide groove 4011 provides sufficient guidance for the support link 401.

[0043] Figure 10 This is a schematic diagram of the stowed state of the support frame assembly according to the second embodiment of the present invention; Figure 11 Schematic diagram of the supporting state of the support frame assembly according to the second embodiment of the present invention. Figure 10 and combined Figure 11 As shown, in this embodiment, the support frame assembly 400 also includes a storage state and a support state.

[0044] like Figure 10 The figure shows the storage state: when the sliding handle 501 slides upward, it can drive the support link 401 to move on the guide frame 502. When the sliding handle 501 moves to a certain distance, the protrusion at one end of the sliding handle 501 cooperates with the groove at one end of the extension tube assembly 200, so that the support frame assembly 400 is locked in the storage state. At this time, the support link 401 and the extension tube assembly 200 fit together.

[0045] like Figure 11 The figure shows the supporting state: when the sliding handle 501 slides downward, it can drive the supporting link 401 to move on the guide frame 502. When the sliding handle 501 moves to a certain distance, the protrusion at the other end of the sliding handle 501 cooperates with the groove at the other end of the extension tube assembly 200, so that the supporting link 401 is locked in the supporting state. At this time, the branch end 403 contacts the ground, thereby achieving the function of supporting the ground.

[0046] In summary, the present invention provides a handheld upright vacuum cleaner that allows users to store the vacuum cleaner upright anytime and anywhere without the help of other objects or disassembly of the vacuum cleaner. The structure is simple and compact, which greatly improves the convenience of use for users.
