Description

Finger expander

Technical field

This utility model relates to a kind of finger expander.

Background technology

White collar operationally, needs long-time use mouse and keyboard work, works after one day, point extremely tired out.Under naturalness, finger is case of bending, if when both hands do not work, finger can be made to keep straight configuration, then can alleviate the tired out of finger preferably.Chinese utility model patent ZL200720157313.3 discloses a kind of elastic finger extension pad, comprises elastic layer and fixing band is characterized in that: the palmation with the elastic pad that elastic plate manufactures being finger extension, and has equally distributed multiple through hole; The two sides of elastic pad is provided with rubber lining, and the palm physiological surface wherein after the lined surfaces of palmar one side and finger extension matches, and thumb fixing band is equipped with at thumb position, and main fixing band is equipped with in all the other four positions, finger, and metacarpus is equipped with palm fixing band.Although this extension pad can play the effect of stretching finger, but its area is comparatively large, palm completely cover by this extension pad, therefore can have a strong impact on the normal use of both hands, as taken cup, tickling, the simple activities of daily life such as wash up all cannot complete.

Utility model content

This utility model mainly solves the technical problem existing for prior art, thus provide one that finger can be kept to be extended configuration, alleviate the fatigue of finger, but finger, wrist still can normally bend, therefore the simple motion in daily life still can complete, the finger expander less on daily life impact.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:

A kind of finger expander, comprise one " C " shape link and a connecting rod, described finger expander also comprises a palmar hand and a finger limiting section, one end and described " C " shape link of described connecting rod are rotationally connected mutually, one end of described palmar hand and the other end of described connecting rod are rotationally connected, the front end of described palmar hand is provided with four connection straps, and the end of described connection strap is provided with a connecting hole; Described finger limiting section comprises a "T"-shaped frame, a spring and a gag lever post, and the lower end of described "T"-shaped frame is a stud, and the middle part of described gag lever post and the upper end of described "T"-shaped frame are rotationally connected; One end of described spring is connected with the right-hand member of described "T"-shaped frame, the other end is connected with one end of described gag lever post; The other end of described gag lever post is provided with a fingerstall; Described stud is threaded with described connecting hole.

The advantage of finger expander of the present utility model is: finger can be kept to be extended configuration, and alleviate the fatigue of finger, but finger, wrist still normally can bend, the simple motion therefore in daily life still can complete, less on daily life impact.

Accompanying drawing explanation

In order to be illustrated more clearly in this utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 1 is the perspective view of finger expander of the present utility model;

Fig. 2 is the perspective view of the palmar hand in Fig. 1;

Fig. 3 is the perspective view of the finger limiting section in Fig. 1;

Wherein:

1, " C " shape link;

2, connecting rod;

3, palmar hand; 31, connection strap; 32, connecting hole;

4, limiting section is pointed; 41, "T"-shaped frame; 411, stud; 42, spring; 43, gag lever post; 431, fingerstall.

Detailed description of the invention

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.

As shown in Figure 1, a kind of finger expander, comprises one " C " shape link 1, connecting rod 2, palmar hand 3 and a finger limiting section 4,

One end of this connecting rod 2 is rotationally connected mutually with this " C " shape link 1, should can be used for fixing in the wrist of people by " C " shape link 1;

One end of this palmar hand 3 and the other end of this connecting rod 2 are rotationally connected, and this architecture can make the palm of people can normally upwards or be bent downwardly;

The front end of this palmar hand 3 is provided with four connection straps 31, and the end of this connection strap 31 is provided with a connecting hole 32;

This finger limiting section 4 comprises "T"-shaped frame 41, spring 42 and a gag lever post 43, and the lower end of this "T"-shaped frame 41 is a stud 411, and the upper end of the middle part of this gag lever post 43 and this "T"-shaped frame 41 is rotationally connected; One end of this spring 42 is connected with the right-hand member of this "T"-shaped frame 41, the other end is connected with one end of this gag lever post 43; The other end of this gag lever post 43 is provided with a fingerstall 431; This stud 411 is threaded with this connecting hole 32.

When user needs to flex one's fingers, only need the pulling force that slightly firmly can overcome this spring 42, can normally flex one's fingers; When user does not exert oneself, this spring 42 can pull finger to straight configuration by this gag lever post 43, reaches the object stretching finger.

From above structure and advantage, this finger expander can keep finger to be straight configuration preferably, thus alleviate the fatigue of finger, but less on the impact that flexes one's fingers normally in daily life, user puts on this finger expander still can complete simple motion in daily life.

Below be only the mentality of designing of some embodiments of the present utility model, when system allows, this utility model can expand to external more functional module simultaneously, thus expands its function to greatest extent.

The above, be only detailed description of the invention of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
