[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] 1. The bottom end of the guiding ring of the present utility model penetrates through the fan positioning sleeve and is connected to the locking ring through a thread. The bottom end of the positioning bent rod penetrates through the guiding ring and the locking ring and is inserted into the inner side of the U-shaped positioning groove. Therefore, the stable connection of the fan positioning sleeve and the connecting seat can be realized by positioning and locking the positioning bent rod. By installing the first locking knob in different positioning holes, the insertion dimension between the support diagonal rod and the support foot rod can be adjusted, and thus the installation height of the tower fan can be adjusted to meet the control of the blowing height.

[0012] 2. The connecting seat and the three support diagonal rods of the present utility model are conveniently connected through the metal connecting piece and the pin. When the bottom end of the support diagonal rod is inserted into the inner side of the support foot rod, the first locking knob is installed in the positioning hole. The bottom end of the first locking knob penetrates through the support foot rod and is threadedly connected to the support diagonal rod. Therefore, it is convenient to fixedly connect the support diagonal rod and the support foot rod through the first locking knob. When the tower fan is placed, the three support diagonal rods and the support foot rods are unfolded relative to the connecting seat through the pin. Therefore, it is convenient to carry out counterweight through the counterweight block to stably support the tower fan. By disassembling the pin, it is convenient to separate the support diagonal rod from the connecting seat, and thus it is convenient to fold and store the whole, effectively reducing the packaging cost and the packaging volume.
