One end of described link is fixedly connected with described arm band, the other end is provided with two supports being arranged in parallel
Plate, is provided with a driving gear and driven gear, described driving gear and described driven tooth between two described gripper shoes
Wheel intermeshing, described driving gear are arranged in the lower section of described driven gear, described driving gear and it is described from
The two ends of moving gear are rotated with two described gripper shoes and are connected, and described driving gear is fixed on the one of described connecting plate
End, described driven gear are fixed on one end of a restoring board；The other end of described restoring board is connected with one end of a spring
Connect, the other end of described spring is connected with described connecting plate.
As preferred embodiments of the present invention, a regulating bolt, described regulating bolt on described restoring board, are provided with
It is connected with one end of described spring.
The advantage of wrist joint fixing device of the present invention is：With spring, after palm off-target fixed position, can
It is subject to reaction force, the activity for alloing palm to be limited in certain limit both prevent wrist joint from occurring stiff impaired in time
Situation, wrist joint can be avoided again to come to harm in activity.

Specific embodiment
Below the preferred embodiments of the present invention are described in detail so that advantages and features of the invention can be easier to by
It will be appreciated by those skilled in the art that apparent clearly defining so as to make to protection scope of the present invention.
The advantage of wrist joint fixing device of the present invention is：With spring, after palm off-target fixed position, can
It is subject to reaction force, the activity for alloing palm to be limited in certain limit both prevent wrist joint from occurring stiff impaired in time
Situation, wrist joint can be avoided again to come to harm in activity.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of wrist joint fixing device, including the palm 1, one arm of a band band 2 and a connecting plate 3,
The wrist joint fixing device also includes a link 4；
One end of the connecting plate 3 and the palm 1 ball-joint of band；
One end of the link 4 and the arm are fixedly connected with 2, the other end is provided with two gripper shoes 41 being arranged in parallel,
A driving gear 42 and driven gear 43 are provided between two gripper shoes 41, the driving gear 42 is mutual with the driven gear 43
Engagement, the driving gear 42 is arranged in the lower section of the driven gear 43, the two ends of the driving gear 42 and the driven gear 43 with
Two gripper shoes 41 rotate connection, and the driving gear 42 is fixed on one end of the connecting plate 3, and the driven gear 43 is fixed on one
One end of restoring board 44；The other end of the restoring board 44 is connected with one end of a spring 45, the other end of the spring 45 with should
