Further, the foot slot 110 for accommodating foot is offered on pedestal 100, leg seat 200 is fixed on pedestal 100, the leg
Offer leg slot 210 for accommodating leg, and leg slot 210 and 110 connection of foot slot on seat 200, when work, patient only need to be by shank
It is placed in leg slot 210, foot is placed in foot slot 110, in this way, working as patient over the course for the treatment of, leg seat 200 can be protected small
Leg, pedestal 100 can protect foot, so that the safer use Multi-functional knee joint of people bends and stretches traction device；When patient exists
When treatment, active force need to be acted on leg seat 200, leg seat 200 is moved on the ground, and at this point, pedestal 100 with
Junction between leg seat 200 can rub with ground, bend and stretch traction device so as to cause the Multi-functional knee joint and grind
Damage, and in the present invention, at least two pulleys 120 are equipped with, and be fixedly arranged on pedestal 100 close to the outer of 200 one end of leg seat
Side, the setting of the pulley 120 not only avoid the junction of pedestal 100 and leg seat 200 there is a situation where wearing, and reduce
Coefficient of frictional resistance between the junction and ground of pedestal 100 and leg seat 200, reduces the loss of active force, so that this is more
The therapeutic effect that function knee joint bends and stretches traction device is more preferable；In the present invention, at least two traction items 220 are additionally provided with,
And it is movably arranged at the lateral surface of leg seat 200, and it is removably connected with mounting bar 230 between two neighboring traction item 220, when work,
People only need active force to act on mounting bar 230, and mounting bar 230 is enabled to be divided into two parts the active force and be transmitted to respectively
On two traction items 220, so that traction item 220 drives leg seat 200 along ground motion；It is slidingly connected on mounting bar 230
Have snap ring 240, when people by active force active force when on snap ring 240, snap ring 240 can be moved between two traction items 220
Stress point on, so that the active force to be divided into the active force of two parts of same sizes, each traction item 220 is born
Active force is identical, in this way, people just can be by bigger active force on snap ring 240, so that people are in use, this is multi-functional
When knee joint bends and stretches traction device, there is better therapeutic effect；Snap ring 240 is online to be connected with dynamometer 250, when work, people
Active force is acted on dynamometer 250, hereafter the active force will be transmitted on snap ring 240 by dynamometer 250, and be worked as
When active force is acted on dynamometer 250, dynamometer 250 will show the size of active force at this time, in this way, people just can root
The size of numerical value, the size of control action power, so that the Multi-functional knee joint bends and stretches traction device stress are shown according to dynamometer 250
Precisely, so that the therapeutic effect of people is more preferable.
Offered on each traction item 220 it is multiple for installing the mounting holes 221 of mounting bar 230, when installation, Ren Menxu
The mounting hole 221 for being suitble to oneself to treat first is selected, and it is right that the both ends of mounting bar 230 are inserted in two traction items 220 respectively
In the mounting hole 221 answered, hereafter, mounting bar 230 and traction item 220 are knotted, to increase or decrease traction item 220 and leg seat
The distance between 200 junction and mounting bar 230, the setting of the mounting hole 221, so that the Multi-functional knee joint bends and stretches traction
Device is more flexible, so that people be facilitated to operate.
On the junction and traction item 220 of traction item 220 and leg seat 200 close to leg seat 200 mounting hole 221 between away from
From the distance between the junction and pedestal 100 for being greater than traction item 220 and leg seat 200, the setting of the mechanism, so that traction item
220 one end far from leg seat 200 rotate to pedestal 100 far from foot slot 110 one side when, mounting bar 230 still can install
On mounting hole 221, so that the Multi-functional knee joint bends and stretches traction device suitable for different therapeutic schemes, so that people
Better therapeutic effect can be obtained.
Dynamometer 250 includes ontology 251, display 252 and hook 253, and 253 activities of hook are inserted in ontology 251,
Display 252 is electrically connected on ontology 251, when people act on active force on hook 253, so that hook 253 is to far from this
When 251 direction of body moves, ontology 251 will generate electric signal, and electric signal is passed to display 252, so that display 252
Numerical value is shown, in this way, people just can be according to the numerical value on display 252, the size of control action power, so that the multi-functional knee closes
Section bends and stretches that traction device stress is accurate, so that the therapeutic effect of people is more preferable.
Pedestal 100 and leg seat 200 are all made of the production of PE polypropylene high temperature sheet, and PE polypropylene high temperature sheet has just
Property good, good toughness, in this way, capableing of the use of the more secure and reliable Multi-functional knee joint as people bends and stretches traction device.
