Subscriber station leans against back support on bottom plate, and foot is placed on leg protector.User holds handle, passes through handle
Hand swings hollow circular-tube to the left, and hollow circular-tube drives ratchet to rotate counterclockwise by rotation axis, and then ratchet and pawl are protected
It holds contact but mismatches.Hollow circular-tube pulls cylinder sliding block to be moved to the left by the wirerope of right, and the first compressed spring is therewith
Compression, cylinder sliding block extend expansion bracket by first connecting rod, and expansion bracket drives the first limited block to move up, the first limit
Block drives leg protector to move up, and then the foot of user moves up.After the foot of user moves to proper height, user decontrols handle
Hand, ratchet and click-fit fix hollow circular-tube, and then leg protector stops movement, and user can carry out leg pressing exercise, such as
This can need to adjust leg pressing height according to user itself, prevent user's moment to be lifted excessively high by leg and pull leg, Neng Goushi
Different height crowds are answered, leg pressing effect can be strengthened.After the completion of leg pressing, user swings hollow circular-tube to the left again, while upwards
Pull rod is pressed, pull rod is swung up pawl left end by the wirerope of left, and the second compressed spring is compressed therewith, pawl right end
Then to lower swing, and then ratchet and pawl are detached from.User swings to the right hollow circular-tube again, and then the wirerope of right loosens,
Under the effect of first compressed spring, first connecting rod moves right resets, and then expansion bracket shortening, the first limited block pass through second connecting rod
Leg protector is driven to move down reset, user can put down foot, releasing lever, under the effect of the second compressed spring, pawl
Right end is swung up reset, and pawl again limits ratchet, and user decontrols handle, can leave from bottom plate.
Foot is placed on leg protector by user, and under the action of user's leg weight, leg protector left part is to lower swing, leg
Portion's protector drives square slider to move down by third connecting rod, and third compressed spring is compressed therewith, so enables to leg
The leg of protector flexible adaptation user makes user that leg pressing exercise more be carried out cosily, can protect user leg, make user more
It is stretched well.After user puts down foot, under the effect of third compressed spring, square slider is moved up, and leg protector is left
Portion is swung up reset.
When leg is lifted up, user holds special-shaped driving lever, and special-shaped driving lever is pressed downward, and special-shaped driving lever makes arcuate struts exist
Slide downward in third sliding slot, and then back support is swung to the right, torque spring stretches therewith, and such back support can
It supports user above the waist, prevents user from falling down during being lifted up leg because of body inclination.User leg lift to
After proper height, special-shaped driving lever is decontroled, under torque spring effect, back support swings reset to the left.
When back support is rocked to the right suitable position, user decontrols special-shaped driving lever, under torque spring effect, swings
Hook catches on rack gear, and so as to fix the position of back support, user can be kept bending over the movement of leg pressing, without
Special-shaped driving lever is persistently pushed down, it being capable of more easily leg pressing.After the completion of leg pressing, user moves to the right swing hook, common spring with
Stretching, swing hook and rack gear and be detached from, back support is swung to the left to be resetted, and user, which unclamps, swings hook, common spring
It resets.
Beneficial effect is: the present invention by user hollow circular-tube is swung to the left so that expansion bracket elongation, can according to
Family itself needs to adjust leg pressing height, and user's moment is prevented to be lifted excessively high by leg and pull leg, can adapt to different height people
Group, can strengthen leg pressing effect；By making leg protector left part to lower swing, enable to leg protector flexible adaptation user's
Leg makes user that leg pressing exercise more be carried out cosily, can protect user leg, stretch user preferably；Pass through
Back support can support user above the waist, prevent user from falling during being lifted up leg because of body inclination
?；It is used cooperatively the movement that family is maintained leg pressing of bending over rack gear by swinging hook, without persistently pushing down special-shaped driving lever,
It being capable of more easily leg pressing.
