Ergonomics nail clipper, including two handles, described handle is respectively handle one and handle two, and its feature exists In: the front end of handle one and handle two is symmetrically arranged with the head that section is in V-shaped, and the free end of head is cutting edge, cutting Tooth shape becomes the otch of shearing；

The wherein rear end of head, symmetrical setting axis hole on handle one and handle two, installs bearing pin, hand simultaneously in axis hole Socket is also set up on handle one, handle one and handle two are linked together after passing through socket by handle two by bearing pin, handle one He Handle two forms the structure of x type, and handle one and handle two can be rotated along bearing pin；

Also include spring leaf, one end of wherein spring leaf is fixed on the medial surface of any one handle rear end, spring leaf Other end contact is not having a handle medial surface of stationary spring, forms sliding end, during handle one motion relative with handle two, The sliding end of spring leaf slides along corresponding handle medial surface.I.e. one end of spring leaf is fixed on inside a handle Face, spring other end contact is in another handle medial surface.

Preferably, described otch is the arc groove of an indent, and arc groove is agreed with the shape of nail.Reduce otch to apply It is added in the pressure on nail, and otch section is smooth, neat.

Preferably, the rear end of handle is provided with lanyard mouth.

The utility model structure is simple, and force when trimming the nails is little, and nail section is smooth, neat.

Brief description

Fig. 1 is the utility model schematic diagram

Figure number illustrates: handle 1, handle 22, head 3, bearing pin 4, socket 5, spring leaf 6, lanyard mouth 7

Specific embodiment

Below in conjunction with the accompanying drawings the utility model is described in detail.

In figure, ergonomics nail clipper includes two handles, spring leafs, and described handle is respectively handle 1 and handle 22, handle 1 and handle 22 front end are symmetrically arranged with the head 3 that section is in substantially V-shaped, formed and hold between the head of handle Receive cavity, the free end of head 3 is cutting edge, and cutting edge forms the otch of shearing nail, when trimming the nails, unnecessary nail Can be contained in cavity, the nail shear offing is taken in cavity, the nail being trimmed to about during shearing getting off will not arbitrarily fly Splash.

The wherein rear end of next-door neighbour's head 3, symmetrical setting axis hole on handle 1 and handle 22, installs bearing pin in axis hole 4, socket 5 is also set up on handle 1 simultaneously, handle 1 and handle 22 are connected after passing through socket 5 by handle 22 by bearing pin 4 Together, handle 1 and handle 22 form the structure of x type, and handle 1 and handle 22 can be rotated along bearing pin 4, Form the principle of lever between bearing pin and handle, the setting of x type simultaneously makes two handles will not separate easily, depart from, only when When bearing pin departs from axis hole, two handles just can separate, and the setting of x type can help reduce the power pressing on handle, As long as easily pinching very much two handles when use so as to relative motion is it is possible to easily prune nail unnecessary Part, and the pressure that cephalic incision part presses on nail is also little, can feel very comfortable, without compromising on finger when pruning First, the section of nail is neat, smooth, attractive in appearance.For stable connection, after handle connects, locking mechanism is set at bearing pin two ends.

In the utility model, the length of socket 5 is slightly long, as long as the movement travel of socket without prejudice to handle two, when During two relative close motions of handle, socket leaves the space of handle two motion.

One end of spring leaf 6 is fixed on the medial surface of any one handle rear end, and one end of such as spring leaf 6 is fixed on hand The medial surface of handle 22 rear end, the other end of spring leaf 6 forms free skating moved end, handle with regard to contact in the medial surface of handle 1 One 1 motions relative with handle 22, such as, during mutually inside relatively close of two handles, handle extrudes eye reed 6, spring Moving freely of piece 6 holds the medial surface along handle 1 to slide, when between handle, inwardly close relative motion completes, release Pressure on spring leaf 6 helps the form before recovery between handle with the sliding end of spring leaf 6.

Described head free end, that is, cut out portion there is the arc groove of an indent, the free end of arc groove is formed cuts Cut sword, arc groove is agreed with the arc of nail.

The rear end of handle is provided with lanyard mouth 7, and lanyard mouth not only can access lanyard, and can mitigate entirety and repair first knife Weight, meanwhile, the rear end of handle carry out round and smooth excessively, during use to hold knob sense more preferable.

These are only the preferred embodiment of the utility model embodiment, do not implement in order to limit the utility model Example, within all spirit in the utility model embodiment and principle, any modification, equivalent substitution and improvement made etc., all should wrap It is contained in the protection domain of the utility model embodiment.
