Patent Application
20180272515
The present invention relates to pliers, and more particularly to multifunctional pliers.
Currently, most multifunctional pliers on the market are disadvantageous due to limited size of the handle. So, they can be used to receive blades with smaller volume that cannot endure relatively large force, which means that these blades are suitable only for cutting paper and relatively soft objects. Therefore, there remains a need for a new and improved design for a multifunctional plier to overcome the problems stated above.
In one aspect, a multifunctional plier may include a first plier unit with a first handle portion, and a second plier unit with a second handle portion. The first plier unit and second plier unit are coupled with a hinge above the first and second handle portions.
In one embodiment, the first handle portion has a rivet at a rear end of the first handle portion to rivetedly connect a first blade and a second blade. When first handle portion is folded in a counterclockwise manner toward the first plier unit, a first receiving space can be seen from the second plier unit, and can be used to receive the first blade and second blade. The first blade and second blade can rotate around the rivet to be unfolded out from the receiving space. A third handle portion that drives the second blade to cut is hinged to the non-cutting end of the second blade. It is noted that the third handle portion can rotate toward the second blade to be folded at an opening of the receiving space.
The first handle portion has a restricting unit and a spring on the opposite side of the receiving space. In one embodiment, the restricting unit is in contact with a stopping edge of the first blade when the first blade 6 rotates to an angle of 180° against the first handle portion to prevent the first blade from further rotating. Without the restricting unit to block the rotation movement of the first blade, the rotating angle of the first blade cannot be limited, and a cutting action cannot be completed with the first blade and second blade.
The second blade has a pressing position of the spring, which can be pressed when second blade rotates to the first blade for cutting. Comparing with a conventional structure with an inner spring when two blades are hinged, this structure can simplify the assembly process of the two blades and reduce the thickness of the blades.
A plurality of small tools can be included within the first handle portion and second handle portion, riveted to a rear end of each first and second handle portions. In one embodiment, small tools riveted to the rear end of first handle portion may include a blade, a nail puller, a can opener, a rope cutter and a screwdriver. In another embodiment, small tools riveted to the rear end of second handle portion may include a saw blade, a file, and a glass knocker.
The detailed description set forth below is intended as a description of the presently exemplary device provided in accordance with aspects of the present invention and is not intended to represent the only forms in which the present invention may be prepared or utilized. It is to be understood, rather, that the same or equivalent functions and components may be accomplished by different embodiments that are also intended to be encompassed within the spirit and scope of the invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which this invention belongs. Although any methods, devices and materials similar or equivalent to those described can be used in the practice or testing of the invention, the exemplary methods, devices and materials are now described.
All publications mentioned are incorporated by reference for the purpose of describing and disclosing, for example, the designs and methodologies that are described in the publications that might be used in connection with the presently described invention. The publications listed or discussed above, below and throughout the text are provided solely for their disclosure prior to the filing date of the present application. Nothing herein is to be construed as an admission that the inventors are not entitled to antedate such disclosure by virtue of prior invention.
As used in the description herein and throughout the claims that follow, the meaning of “a”, “an”, and “the” includes reference to the plural unless the context clearly dictates otherwise. Also, as used in the description herein and throughout the claims that follow, the terms “comprise or comprising”, “include or including”, “have or having”, “contain or containing” and the like are to be understood to be open-ended, i.e., to mean including but not limited to.
