As shown in Figures 4 to 6, when operation, user is by turning knob 137, so that adjustment bar 125 moves up and down.Such as
Shown in Fig. 5, when adjustment bar 125 up moves, the position of blade 11 in a fluid is shallower, then its rotary resistance is lighter.Such as Fig. 6 institute
Show, when adjustment bar 125 moves down, the position of blade 11 in a fluid is deeper, then its rotary resistance is heavier.Whereby, it is possible to provide
Sports equipment 1 has different resistances.
Fig. 7 and Fig. 8 is partial perspective view, and Fig. 9 and Figure 10 are side view, shows movement according to a third embodiment of the present invention
Equipment 3, wherein to clearly show that certain features, Fig. 7 and Fig. 8 do not draw subelement.The present embodiment and first embodiment
It does not exist together and is only that adjustment device 13 ", remaining element are identical with the first embodiment, repeat no more.
As shown in Figure 7 and Figure 8, adjustment device 13 " have mandrel 141, operating parts 142, sleeve 143, two springs 144,
Fixinig plate 145, connector 146, support chip 147.Fixinig plate 145 is fixed between two side pipes 22.Mandrel 141 passes through sleeve
143, the upper end of mandrel 141 and fixinig plate 145 are fixed, and the lower end of mandrel 141 and upper support tube 23 are fixed.Operating parts 142 passes through
The opening (not shown) of sleeve 143.Support chip 147 and sleeve 143 are fixed, using the supporting point as force.In another embodiment
In, support chip 147 is omitted.In addition, two springs 144 are located inside sleeve 143, it is located at the two sides of operating parts 142 simultaneously
And it is passed through by mandrel 141.Wherein, each spring 144 has a first end and a second end, and wherein first end connection sleeve 143 is interior
Wall, second end attended operation part 142.
As shown in Fig. 7 to 10, in predetermined condition, that is, when user does not have pressing operation part 142, so that two springs
144 internal diameter is less than the outer diameter of mandrel 141；At this point, spring 144 is strutted by mandrel 141, locked using the reversed torsion of spring 144
Tight long axis 445 can not move so that sleeve 143 is locked in mandrel 141 along mandrel 141.When user is with support chip
147 be supporting point pressing operation part 142, so that the internal diameter of spring 144 becomes larger, the internal diameter of spring 144 is greater than the outer of mandrel 141
Diameter, mandrel 141 are no longer lockked by spring 144, and sleeve 143 can be moved up and down along long axis 44.Distinguish at the both ends of connector 146
Connection adjustment bar 125 and sleeve 143.Therefore when sleeve 143 moves up and down, adjustment bar 125 is also and then moved up and down.
As shown in figure 9, position of the blade 11 in fluid 15 is shallower, then its rotary resistance when adjustment bar 125 up moves
It is relatively light.As shown in Figure 10, when adjustment bar 125 move down, position of the blade 11 in fluid 15 is deeper, then its rotary resistance compared with
Weight.Whereby, it is possible to provide sports equipment 1 has different resistances.
According to embodiments of the present invention provided by sports equipment, user can easily, rapidly adjust operation resistance.
