Cutting tool having detachable grips

Abstract

A cutting tool includes two metal handles each having a first end formed with a mounting portion and a second end formed with a blade portion, and two plastic grips each having an inside formed with a mounting hole mounted on the mounting portion of the respective metal handle. The mounting hole of each of the plastic grips has a first end formed with a first separation slot and a second end formed with a second separation slot. Thus, the plastic grips are detachable from the metal handles when the cutting tool is worn out, so that the plastic grips and the metal handles are separated from each other, thereby facilitating reuse of the plastic grips and the metal handles.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a cutting tool and, more particularly, to a cutting tool, such as a pair of scissors and the like.

2. Description of the Related Art

A conventional cutting tool, such as a pair of scissors and the like, comprises two metal handles pivotally connected with each other and each having a first end formed with a shank and a second end formed with a blade, and two plastic grips each fixed on the shank of a respective one of the metal handles. However, the plastic grips are fixed on the metal handles without detachment, so that the plastic grips cannot be separated from the metal handles when the cutting tool is worn out, thereby causing inconvenience in reuse of the plastic grips and the metal handles.

BRIEF SUMMARY OF THE INVENTION

In accordance with the present invention, there is provided a cutting tool, comprising two metal handles pivotally connected with each other and each having a first end formed with a mounting portion and a second end formed with a blade portion, and two plastic grips each mounted on a respective one of the metal handles and each having an inside formed with a mounting hole mounted on the mounting portion of the respective metal handle. The mounting hole of each of the plastic grips has a first end formed with a first separation slot and a second end formed with a second separation slot.

The primary objective of the present invention is to provide a cutting tool having detachable grips.

Another objective of the present invention is to provide a cutting tool, wherein the plastic grips are detachable from the metal handles when the cutting tool is worn out, so that the plastic grips and the metal handles are separated from each other, thereby facilitating reuse of the plastic grips and the metal handles.

A further objective of the present invention is to provide a cutting tool, wherein the user applies a bending force on the plastic grips relative to the metal handles to break the first separation slot and the second separation slot of each of the plastic grips, thereby separating the plastic grips from the metal handles.

A further objective of the present invention is to provide a cutting tool, wherein the bending force is applied on the first separation slot and the second separation slot of each of the plastic grips from the starting portion having the smallest thickness and weakest strength so that the first separation slot and the second separation slot of each of the plastic grips are broken easily and rapidly, thereby saving the manual work, and thereby facilitating the user separating the plastic grips from the metal handles.

Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially to FIGS. 1-3, a cutting tool in accordance with the preferred embodiment of the present invention comprises two metal handles 10 pivotally connected with each other and each having a first end formed with a mounting portion 11 and a second end formed with a blade portion 12, and two plastic grips 20 each mounted on a respective one of the metal handles 10 and each having an inside formed with a mounting hole 21 mounted on the mounting portion 11 of the respective metal handle 10.

The mounting hole 21 of each of the plastic grips 20 has a first end formed with a first separation slot 22 and a second end formed with a second separation slot 23. The first separation slot 22 and the second separation slot 23 are located at two opposite sides of the mounting hole 21 of each of the plastic grips 20. The first end of the mounting hole 21 of each of the plastic grips 20 has an open wall, and the second end of the mounting hole 21 of each of the plastic grips 20 has a closed wall.

The first separation slot 22 of each of the plastic grips 20 has an outer side having a starting portion 24 and an ending portion 25. The outer side of the first separation slot 22 of each of the plastic grips 20 has a thickness gradually increased from the starting portion 24 to the ending portion 25.

The second separation slot 23 of each of the plastic grips 20 has an outer side having a starting portion 26 and an ending portion 27. The outer side of the second separation slot 23 of each of the plastic grips 20 has a thickness gradually increased from the starting portion 26 to the ending portion 27.

As shown in FIG. 4, when a user wishes to separate the plastic grips 20 from the metal handles 10, the user applies a bending force on the plastic grips 20 relative to the metal handles 10. In such a manner, the mounting portion 11 of each of the metal handles 10 has a front end pushed toward the first separation slot 22 of the respective plastic grip 20 by the bending force and a rear end pushed toward the second separation slot 23 of the respective plastic grip 20 by the bending force so as to bend the first separation slot 22 and the second separation slot 23 of each of the plastic grips 20, thereby separating the plastic grips 20 from the metal handles 10. At this time, the bending force is applied on the first separation slot 22 and the second separation slot 23 of each of the plastic grips 20 from the starting portion 24 and 26 having the smallest thickness and weakest strength so that the first separation slot 22 and the second separation slot 23 of each of the plastic grips 20 are bent easily and rapidly, thereby saving the manual work, and thereby facilitating the user separating the plastic grips 20 from the metal handles 10.

As shown in FIG. 2, the cutting tool further comprises a protective cover 30 mounted on the blade portions 12 of the metal handles 10 to protect the blade portions 12 of the metal handles 10. In addition, the protective cover 30 is mounted on the blade portions 12 of the metal handles 10 to hold the metal handles 10 so that the user's hand can hold the protective cover 30 to apply the bending force on the plastic grips 20 so as to bend the plastic grips 20 by the metal handles 10, thereby separating the plastic grips 20 from the metal handles 10.

As shown in FIGS. 5 and 6, each of the plastic grips 20 has a surface that is cut to form the first separation slot 22 and the second separation slot 23.

Accordingly, the plastic grips 20 are detachable from the metal handles 10 when the cutting tool is worn out, so that the plastic grips 20 and the metal handles 10 are separated from each other, thereby facilitating reuse of the plastic grips 20 and the metal handles 10. In addition, the user applies a bending force on the plastic grips 20 relative to the metal handles 10 to break the first separation slot 22 and the second separation slot 23 of each of the plastic grips 20, thereby separating the plastic grips 20 from the metal handles 10. Further, the bending force is applied on the first separation slot 22 and the second separation slot 23 of each of the plastic grips 20 from the starting portion 24 and 26 having the smallest thickness and weakest strength so that the first separation slot 22 and the second separation slot 23 of each of the plastic grips 20 are broken easily and rapidly, thereby saving the manual work, and thereby facilitating the user separating the plastic grips 20 from the metal handles 10.

Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
