The utility model discloses in the straight and bucking state of patient's wrist as shown in figure 1, A is the straight state of wrist in figure 1, and B is the bucking state.

It is desirable that the wrist of the patient be maintained in a flat condition as shown in fig. 2 during rehabilitation using the pneumatic glove system to avoid interference with the motion of the pneumatic glove in flexion.

A lace tightening device is provided in the prior art, such as "a lace adjusting device and assembly" disclosed in international patent application publication No. WO2019169732A1, which device "includes a driving member, a winding member, and an adjusting member; the driving piece, the winding piece and the adjusting piece are coaxially arranged; the driving piece and the winding piece are movably connected with the adjusting piece; the driving piece is used for driving the wire winding piece to rotate along the axial direction; the winding piece is provided with a winding post and an elastic sheet, and the winding post is provided with a fixing part for fixing the binding band; the adjusting piece is provided with an annular rack matched with the elastic sheet. When a user fixes the lace through the binding band, the lace adjusting device can avoid binding operation, and only one hand is needed to rotate the operation driving piece (the tightness adjustment can be completed, the operation is simple, the time is saved, and the use by a beginner or a user with inconvenient use of both hands is particularly convenient ". Besides, independent products and accessories of the lace adjusting device are sold as commodities on the market, such as a device with the trademark of 'Fitgo'.

In one embodiment according to the present invention, as shown in fig. 3, a pull-cord tightening device 2 is provided on the arm fixing ring 1. The traction rope tightening device 2 may have the same or similar structure as the "rope belt adjusting device" described in WO2019169732A1, or may be a "Fitgo" purchased directly on the market or other device capable of achieving similar functions, and the present invention is not intended to limit this. In a preferred embodiment, the pull cord take-up device 2 includes a take-up knob 21 and two pull cords 22. When the rope retracting knob 21 is pressed and rotated, the pulling rope 22 can be tightened and fixed; when the rope take-up knob 21 is pulled up, the pulling rope 22 is loosened and can be pulled out. In a preferred embodiment, the arm fixing ring 1 is a C-shaped ring.
