Sliding block 313 at least provided with four, and is slideably positioned on support rod 312, and the side of sliding block 313 is provided with hand Fixed device 4.

In the present embodiment, oscillating rod 311 swings swinging of can driving the support rod 312 reciprocal, and ordinary circumstance is divided into Four sliding blocks 313 are set, when in use, are fixed to four fingers of patient by the place of close end by hand fixing device 4 On each sliding block 313, sliding block 313 is realized for patient hand and is held when following support rod 312 to swing back and forth In addition such as in situation biggish for spacing between finger the sliding block 313 more than four can be set, so in active actions A finger is placed every a sliding block 313 afterwards, it is also possible, it is selected according to corresponding concrete condition, it is very convenient.

Further, spring 314 is provided between two neighboring sliding block 313, spring 314 is for tensing two neighboring sliding block 313。

In the present embodiment, for some patients operated separately for being merely able to carry out between each finger, pass through mechanism In the case where may be implemented to hold Zhang Yundong, the opening between each finger can also be carried out, spring 314, Ke Yila is provided with Tight adjacent sliding block 313, it is possible to when patient open between each finger, play the role of exercise.

Further, minitype cylinder 315 is additionally provided between two neighboring sliding block 313, the cylinder body fixation of minitype cylinder 315 is set It sets on a sliding block 313 wherein, the telescopic rod of minitype cylinder 315 is contacted with adjacent sliding block 313.

In the present embodiment, it is additionally provided with minitype cylinder 315 between two neighboring sliding block 313, so for some hands Complete immotile patient not only may be implemented the exercise that hand is held, can also pass through cylinder when using the mechanism 315 flexible realizes separation between sliding block 313 and close, thus realize separation between each finger of patient hand with Close to movement, have the function that more comprehensively movable hand and function are more advantageous to patient to accelerate patient hand's blood circulation Rehabilitation is additionally provided with baffle close to the position of sliding block 313 in the side of limited block 2, can play and carry out one to patient's arm The effect of limit prevents hand and moves outward close to the part of arm when hand holds operation.

Further, hand activities device 3 includes

Fixed block 321 is arranged on bracket 1,

It around bar 322, swings and is arranged on fixed block 321, and be arranged in parallel with several, the side around bar 322 is respectively provided with There is hand fixing device 4, is looped around outside limited block 2 after the swing of bar 322.

In the present embodiment, four are equivalent to four fingers of a people around bar 322, and fixed block 321 is equivalent to palm, lead to It crosses and patient hand is fixed on around bar 322 close to the side of limited block 2, be then wrapped around bar 322 and carry out what similar hand was held Operation, thus to realize the movement for driving patient hand to grasp.

It further, include several connecting rods 3221 around bar 322, several connecting rods 3221 are successively hinged, positioned at edge One connecting rod 3221 and fixed block 321 are hinged, and the side on connecting rod 3221 far from limited block 2 is provided with drive rod 3222, Gu Determine to be provided with drive rod 3222 on block 321, is provided with the second minitype cylinder 3223 between two neighboring drive rod 3222, second The cylinder body and telescopic rod of minitype cylinder 3223 are hinged with two adjacent drive rods 3222 respectively.

In the present embodiment, by controlling the flexible of each second minitype cylinder 3223, realize and second minitype cylinder Angle change between 3223 two adjacent connecting rods 3221, so as to reach the function of holding of similar manpower, in fixation By the flexible of the second minitype cylinder 3223 between block 321 and the connecting rod 3221 adjacent with fixed block 321, connecting rod 3221 is realized With the angle change between fixed block 321, to realize the function that connecting rod 3221 is looped around outside limited block 2.

Further, hand fixing device 4 is any one in elastic band, mutually bonding and rope.

In the present embodiment, hand fixing device 4 can be elastic band, mutually bonding or rope, may be implemented for patient It is relatively common while the fixation of finger and cheap, meet the demand that mass production uses.

Further, fluted 316 are arranged on sliding block 313, minitype cylinder 315 and spring 314 are arranged in groove 316.

In the present embodiment, minitype cylinder 315 and spring 314 are arranged in groove 313, because of 315 cylinder body of minitype cylinder It is hidden in groove 313, spring 314 is also hidden in groove 313, so can infinitely lean between adjacent sliding block 313 Closely, separation and close function between patient's finger are realized to the full extent.

Further, motor is provided on bracket 1, the transmission shaft of motor is connect with oscillating rod 311.

In the present embodiment, motor is arranged on bracket 1, using motor, is also easier to control, oscillating rod easy to accomplish 311 swing.

The present invention also proposes a kind of wheelchair, comprising: claim 1-9 any one hand activities mechanism

In the present embodiment, the hand activities mechanism is set in the end of two placement arm positions of wheelchair, is realized for one Hand activities of a little not flexible patients of legs and feet when going out or using wheelchair, the time for taking full advantage of patient carry out hand Activity largely reduces the hand restorative time.

The above is merely preferred embodiments of the present invention, be not intended to limit the invention, it is all in spirit of the invention and Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
