Referring to FIG. 2 and FIG. 3 at the same time, FIG. 2 is an exploded perspective view showing the dual-use mobile assistant of the present invention, and FIG. 3 shows an exploded side view of the dual-use mobile assistant of the present invention; 50 includes a front support frame 60 and two rear support frames 70.

The front support frame 60 has two side frames 61 and a connecting rod 62. The two side frames 61 include a front pole 611 and an upper cross bar 612 connected to the top of the front pole 611, respectively. The lower cross bar 614 of the shaft of the front vertical rod 611 is provided with an end joint member at the end, and the end joint member may be various joint parts. In this embodiment, the end joint member is preferably a connecting nut. 613, a screw hole 616 is provided at an end of the lower crossbar 614, and two ends of the connecting rod 62 are respectively connected to the two side frames 61.

The two rear support frames 70 each have a rear vertical pole 71 and a rear horizontal pole 72 connected to the top of the rear vertical pole 71. The rear vertical pole 71 is provided with a perforation and can be fixed by a bolt 617 to the lower horizontal pole. A screw hole 616 at the end of the 614, and an end joint member at the end of the rear crossbar 72 can be combined with an end joint member of the upper crossbar 612. Preferably, the end joint members of the rear crossbar 72 can be various joint parts In this embodiment, the end joint is preferably a connecting screw 73, and the connecting screw 73 can be screwed with the connecting nut 613.

Preferably, a pivot portion 615 can also be provided at the joint of the front pole 611 shaft and the lower cross bar 614, so that the lower cross bar can be folded corresponding to the front pole 611, so as to be disassembled and stored Can save more space.

Preferably, the rear crossbar 72 can be sleeved with a grip cover 721. The grip cover 721 can be made of an elastic material such as sponge or rubber, which can make the hand more comfortable and less slippery.

Preferably, the bottom ends of the two front uprights 611 are respectively connected to an adjustment rod 80, so that the height can be adjusted, and the distance between the upper crossbar 612 and the ground can be changed to apply different heights; similarly, the bottom ends of the two rear uprights 71 An adjustment rod 80 is also connected to adjust the height, and the distance of the rear crossbar 72 from the ground is changed to apply different heights. The adjustment rod 80 is usually provided with several adjustment holes 81, and the different adjustment holes 81 correspond to a tenon to adjust the length. This is a general practice and will not be described here.
