This application claims the priority benefit of China Patent Application No. 201710555963.1, filed on Jul. 10, 2017, which is incorporated by reference in its entirety.

TECHNICAL FIELD

The present invention relates to a pair of pet nail clippers.

BACKGROUND

With the improvement of people's living standard, pets have entered millions of households. The daily trimming of pets' nails is for not only beauty but also health of pets. Untrimmed nails may cause a variety of health problems. For example, long nails may break, ache and bleed. In extreme cases, nails may curl and grow into the pets' paws. Nails of pets, such as dogs or cats, grow quickly and have to be trimmed once or twice a month.
However, trimming pets' nails also bring some hidden dangers. With the root of a pet's nails rich in blood capillaries, it is generally not easy to judge how long to cut while trimming the pet's nails, and often only until the pet issues a cry or bleeds is the pet found to have been hurt. Besides, since a pair of pet nail clippers is different from that for human's nails and tends to be larger in size and more complicated in structure, a user may not be able to see parts of a pet's nails to be trimmed while trimming the pet's nails due to the blade or other structural portions of the pair of pet nail clippers blocking the line of sight of the user, which makes the pet more vulnerable.

SUMMARY

A purpose of the present invention is to provide a pair of safe pet nail clippers with a higher safety factor, in which the caliber of the initial trimming hole can be adjusted and controlled within a certain range by an adjustment mechanism according to the size of a pet's nails, so as to prevent the pet from being hurt due to excessive trimming and thus be safer to use.
A technical solution of the present invention is as follows: A pair of safe pet nail clippers is provided, comprising a first member and a second member correspondingly disposed and pivotedly connected to each other, the first and second members respectively comprising a blade portion and a handle portion; with blades of the blade portions of the first and second members provided in a concave shape, when the handle portions of the first and second members are relatively opened to the maximum extent, an initial trimming hole is formed between the concave blades of the first and second members, with the first and second members provided therebetween with an adjustment mechanism for adjusting the relative opening of the handle portions of the first and second members and the caliber of the initial trimming hole.
Preferably, the first and second members are provided therebetween with a reset mechanism for keeping the concave blades of the first and second members in the position of the initial trimming hole.
A further technical solution of the present invention is as follows: The adjustment mechanism comprises a turntable, a first screw located on the left side of the turntable and driven to rotate by the turntable, a second screw located on the right side of the turntable and driven to rotate by the turntable, a first limit block screwed on the first screw, and a second limit block screwed on the second screw, wherein the handle portions of the first and second members are provided oppositely with a first mounting slot and a second mounting slot, into which the first and second screws are inserted, with the threads on the two screws arranged in the reverse direction; the first and second limit blocks are respectively located in the first and second mounting slots and can move laterally relative to them, with notches of the first and second mounting slots smaller than the first and second limit blocks; when the turntable is rotated, it simultaneously drives the first and second screws to rotate, and the first and second limit blocks are moved axially close to or away from each other so as to adjust the distance between the first and second limit blocks, thus adjusting the relative opening of the handle portions of the first and second members and the caliber of the initial trimming hole.
The reset mechanism comprises a first spring and a second spring, wherein the first spring is sleeved on the first screw, with one end thereof abutting on the handle portion of the first member and the other end thereof abutting on the left side of the turntable, and the second spring is sleeved on the second screw, with one end thereof abutting on the handle portion of the second member and the other end thereof abutting on the right side of the turntable. Wherein the first and second springs are preferably conical springs, the larger ends thereof abutting on the handle portion of the first or second member, the smaller ends thereof abutting on the left or right side of the turntable. The reset mechanism may also be a reset member disposed between the handle portions of the first and second members. Wherein the reset member may be a spring or an elastic sheet.
Another further technical solution of the present invention is as follows: The adjustment mechanism comprises an adjustment sheet, which is rotatably connected to the first member and provided with multi-level tooth grooves; the second member is provided with a convex tooth portion matched with the tooth grooves; through engagement of the convex tooth portion of the second member with the different tooth grooves of the adjustment sheet, the relative opening of the handle portions of the first and second members and the caliber of the initial trimming hole are adjusted.
