Preferably, in this embodiment, the cover plate 400 is made of a transparent material, and may specifically be glass, transparent plastic, etc., and the material can be selected according to actual requirements, which is not limited herein and is within the protection scope of the present invention.

Further, referring to fig. 5, the cover 400 has two opposite end surfaces, one end surface abuts against the supporting portion 200, and the other end surface is flush with a side of the visible area 110 away from the external device.

In this embodiment, the cover plate 400 can be adhered to the supporting portion 200 and the gripping portion 100 by an adhesive, and of course, other fixing methods can be adopted, such as fixing a fastener, which is within the protection scope of the present invention and is not described herein.

Preferably, in fig. 1 and 2, the mounting portion 300 has a limiting boss 310 extending toward the cover plate 400, and the cover plate 400 has a limiting hole corresponding to the limiting boss 310. Spacing boss 310 cooperatees with spacing hole to carry on spacingly to apron 400, avoid apron 400 to take place to rotate the relative portion of grasping 100, influence the result of use.

In actual production, this spacing boss 310 can be polygonal column structure, can restrict apron 400 relative the take place to rotate for grasping portion 100 can, all be within the scope of protection of the utility model. In some embodiments, a limiting block may be further disposed on a side wall of the visible region 110, and a groove matched with the limiting block is disposed at a position opposite to the cover plate 400, so as to limit the cover plate 400.

Specifically, referring to fig. 1 to 4, the plurality of mounting interfaces are a first mounting interface and a second mounting interface respectively disposed on a side of the mounting portion 300 facing the external device. The first mounting interface includes a threaded hole 320 and two limiting grooves 330. The two limiting grooves 330 are symmetrically disposed in the peripheral side region of the threaded hole 320. At this time, the screw hole 320 fixes the grasping portion 100 to the external device through a screw, and the limiting groove 330 is engaged with the engaging block of the external device to limit the external device. In contrast, the second mounting interface includes two fastening holes 340, and the two fastening holes 340 are symmetrically disposed in the peripheral side region of the threaded hole 320, and are used for docking the quick release member, so as to fix the grip portion 100 to the external device.

In the present embodiment, the mounting portion 300 has two mounting manners to fix the grip portion 100 to different external devices. One, screw hole 320 is fixed in external device through the screw with grasping portion 100, and spacing groove 330 cooperates with the block looks inlay card of locating external device to carry on spacingly to external device, avoid the patient when carrying out wrist joint rotation training and forearm internal-external rotation training, grabbing device drops from external device. Secondly, the fastening hole 340 is used for abutting against the quick-release member so as to fix the grip portion 100 to the external device, and the installation is convenient and quick. According to the embodiment, a proper installation mode can be flexibly selected according to actual conditions, the universality of the gripping device is improved, and the application range of the gripping device is expanded.

In actual production, also can change spacing groove 330 for the stopper, at this moment, can realize limiting displacement equally in external equipment setting and stopper looks inlay card complex block groove, can set up according to actual conditions is nimble, does not make the restriction here, all is in the utility model discloses an within the protection scope.

Specifically, referring to fig. 5, a tool withdrawal groove 350 is formed in one side of the threaded hole 320 facing the external device, so that an automatic machine is conveniently used for producing and processing the gripping device provided by the embodiment, which is beneficial to mass production and reduces cost.

Preferably, referring to fig. 4, the grasping slot 120 is arcuately configured in cross-section to fit the shape of a patient's finger. At this moment, grab groove 120 and can also play certain limiting displacement, prevent that the patient from in the training process, the finger breaks away from corresponding groove 120 of grabbing, influences the training effect. In addition, in the training process, if the hand of the patient accidentally breaks away from the gripping device, certain potential safety hazards such as wrist sprain and the like can be caused, and secondary damage can be easily caused to the hand of the patient.

Specifically, the limiting groove is of an arc-like shape structure with the radius of 10mm and the opening of 11.5mm, so that the limiting groove is matched with the finger contours of most patients, and the comfort level of the patients in use is improved.

Furthermore, grab groove 120 surface and be equipped with anti-skidding cushion, increase the static friction power between patient's finger and the groove 120 of grabbing, further avoid the patient to take place from the condition that gripping portion 100 drops at the in-process hand of training, when guaranteeing the training effect, improved the security of product.

Of course, in actual production, the same kind of effect can be achieved by disposing a plurality of protruding points or protruding strips on the surface of the grabbing groove 120, which is within the protection scope of the present invention and is not limited herein.

To further improve the comfort of the patient during use, in a preferred embodiment, the grip portion 100 is made of a foam material, and the support portion 200 and the mounting portion 300 are made of a metal material.
