Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Refer to Fig. 1, a kind of embodiment that the utility model is provided：A kind of basketball stands of physical education, including longitudinal direction
One group of hollow shell 2 is fixed at support bar 1 and transverse support bar 14, the top of the vertical supporting bar 1, the hollow shell 2
Inside is provided with hollow-core construction 3, and one group of helical spring 10, one end of the helical spring 10 are placed in the inside of the hollow shell 2
One group of piston 4 is fixed, the other end of the helical spring 10 connects one group of touch panel 5, and the end face of the piston 4 is fixed one group and passed through
The piston rod 6 of the hollow shell 2 is worn, and is connected through a screw thread between the piston rod 6 and hollow shell 2, the piston rod 6
One end fix one group of swingle 7, one end of the touch panel 5 is provided with one group of body of rod 8 through the hollow shell 2, the bar
One group of friction plate 11 is fixed in one end of body 8, and one group of limiting plate 9 is fixed at the top of the hollow-core construction 2, the limiting plate 9 with
The opposed one side of the friction plate 11 fixes one group of portable plate 13 by rotary shaft 12, and the end of the rotary shaft 12 leads to
The inside that bearing is connected to the portable plate 13 is crossed, transverse support bar 14 described in a group is fixed in the side of the portable plate 13；Institute
