BEST MODE FOR CARRYING OUT THE INVENTION

For the convenience of the description, the central idea expressed by the present invention in the column of the above summary of the invention is expressed by the specific embodiments. The various items in the examples are set forth in proportions that are suitable for the description, and not in proportion to the actual elements.

Referring to Figures 1-7, the present invention provides a folding cutter 100 comprising:

a shank 10 having an accommodating space 11 therein, the accommodating space 11 having a lateral opening 12, and in the preferred embodiment of the present invention, the shank 10 is assembled from two mutually parallel plates 13. The accommodating space 11 is located between the two sheets 13 .

A dustproof sheet 20 is fixed between the two sheets 13 and located on the opposite side of the lateral opening 12 for shielding the accommodating space 11, and the side edge of the dustproof sheet 20 has an extended portion 21 In order to increase the frictional force when the user holds the handle 10, the end of the dustproof sheet 20 has a tool hole 22, so that the present invention can also be used as a driving tool, and in the embodiment of the present invention The tool hole 22 is hexagonal.

A shank 30 has a pivoting end 31 pivotally disposed at an end of the shank 10. Preferably, the pivoting end 31 is a gear structure that is pivotally mounted to the two slabs 13 by a gear post 32. Between the pivoting end 31 and each of the plates 13, there is a washer 33. In addition, the blade body 30 has a locking groove 34 and a hook groove 35 adjacent to the pivoting end 31, wherein the hook groove 35 Located between the retaining groove 34 and the pivoting end 31.

A control member 40 is pivotally disposed on the shank 10, and a portion of the opposite side of the lateral opening 12 is exposed to the shank 10 and is located between the dustproof member 20 and the pivoting end 31 of the blade body 30, as shown in FIG. As shown, the control member 40 is also a gear structure that is pivotally disposed between the two plates 13 by a gear post 41, and a washer 42 is also disposed between the control member 40 and each of the plates 13.

In addition, the control member 40 is engaged with the pivoting end 31 of the cutter body 30, thereby controlling the cutter body 30 to be the shaft center of the gear column 32, swinging between a folded position and a deployed position, wherein, when located at the folding position, The blade body 30 is received in the accommodating space 11 as shown in FIG. 6 , and when in the deployed position, the blade body 30 is separated from the accommodating space 11 from the lateral opening 12 and is at the same level as the shank 10 , as shown in FIG. 4 . At this time, the blade edge 36 of the blade body 30 is located on the same side as the lateral opening 12.

A fixing member 50 is pivotally disposed on the shank 10 and located on the opposite side of the lateral opening 12, and preferably, is located beside the control member 40 and the pivoting end 31, and the fixing member 50 is supported by a stop post The pivoting member 51 is pivotally disposed between the two plates 13. When the blade body 30 is in the deployed position, the fixing member 50 can be locked to the fixing groove 34 for limiting the fixed blade body 30 in the deployed position, as shown in FIG. At this time, the hook groove 35 of the cutter body 30 is hooked on the stop post 51, and when the cutter body 30 is in the folded position, the fixing member 50 can be locked to a tooth of the control member 40, so that the control member 40 cannot be Rotating, thereby limiting the fixed body 30 in the folded position, as shown in FIG.

The above is an overview of the structure and shape of the present invention, and the method of use of the present invention and the principle of efficacy that can be achieved are as follows:

The folding cutter 100 of the present invention is in a folded position as shown in FIGS. 6 and 7 in a normal state, which is convenient for the user to store, and when the user wants to use the folding cutter 100, it pulls the fixing member 50 away from the control member. 40, and after the control member 40 is toggled, the cutter body 30 can be swung into a deployed position, as shown in FIG. 1 and FIG. 4, and at this time, the user can be fastened to the cutter body 30 by the fixing member 50. The fixing groove 34 limits the fixing of the cutter body 30 to facilitate the user to use the folding cutter 100.

After the use is completed, the user pulls the fixing member 50 away from the cutter body 30, and toggles the control member 40 in the opposite direction. As shown in FIG. 5, the cutter body 30 can be returned to the folding position, and then borrowed. The fixing member 50 is fastened to the control member 40 to position the blade body 30 to prevent it from sliding out of the lateral opening 12 of the accommodating space 11.

The action of the above-mentioned pulling fixing member 50 and the toggle control member 40 can be completed by a single hand, as shown in FIG. 3, therefore, the folding cutter 100 of the present invention can facilitate the user to operate with one hand. It can control the knife body 30 to be in the folding position or the unfolding position by one hand, which is very convenient, and can be dealt with immediately in case of an emergency.

In addition, the present invention can limit the position of the cutter body 30 in the folded position or the unfolded position by the design of the fixing member 50, thereby improving the safety of the folding cutter 100 during use and preventing the user from being stabbed by the cutter body 30. And, more preferably, the position of the cutter body 30 can be fixed by the fixing member 50 being fastened to the control member 40. Therefore, the present invention can limit the angle of the fixed cutter body 30 relative to the shank 10 for use. The need for different angles increases the breadth of use of the folding tool 100.

The above embodiments are merely illustrative of the invention and are not intended to limit the scope of the invention. All modifications or changes made without departing from the spirit of the invention are within the scope of the invention.
