Advantage and the good effect that the utlity model has are:
By adopting the Ring knife that partly constitutes by straight knife body portion and finger ring shape, finger can be inserted finger ring shape part, cut off adhesive tape easily and flexibly, after finishing using, can be stuck in Ring knife on the adhesive tape or the straight knife body portion is inserted on the inside paper roll of adhesive tape, with getting, make things convenient for user's operation of packing with usefulness.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an axonometric drawing of the present utility model;
Fig. 3 is that the utility model is clamped on the structural representation on the adhesive tape.
Among the figure: 1, straight knife body portion; 2, finger ring shape part; 3, blade; 4, point of a knife; 5, adhesive tape.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1-3, a kind of Ring knife that is used to cut off adhesive tape, the finger ring shape part 2 that comprises the straight knife body portion 1 of cutting off adhesive tape and can insert finger, described straight knife body portion and finger ring shape part are by steel spring plate one roll-forming, end away from finger ring shape part on the straight knife body is provided with blade 3, and the end of described blade is provided with point of a knife 4.Concrete, described blade can be straight sword also can be the circular arc sword, considers from the angle that is easy to process, in the present embodiment, blade is straight sword, and the side of described blade and straight knife body is in a certain angle, this angle is advisable with 30 °~60 °, is preferably 45 ° in the present embodiment.The width of above-mentioned straight knife body portion and finger ring shape part is advisable with 2~3mm, and thickness is advisable with 0.5~0.8mm, is preferably respectively in the present embodiment: 2.5mm and 0.6mm; For the internal diameter size of finger ring shape part, consider the thickness difference that the user points, be advisable with 12~17mm, in the present embodiment, the internal diameter of finger ring shape part is preferably 14mm.Above-mentioned Ring knife will be clamped on the adhesive tape 5 or the straight knife body portion is inserted on the inside paper roll of adhesive tape under no situation, so the length of straight knife body portion will suit.At present, the width of film matter adhesive tape commonly used is 60mm, cuts off adhesive tape and prevents that point of a knife from stretching out two aspects of hurting sb.'s feelings from adhesive tape and considering that the length of described straight knife body portion is 30~55mm from satisfying the user.It is to compress and the medial surface of the upper end of finger ring shape part and inner paper roll compressed by the outermost layer with the lower surface of straight knife body portion and adhesive tape to realize that above-mentioned Ring knife is clamped on the adhesive tape.At present, the thickness of film matter adhesive tape commonly used is 10mm, consider from the angle of being convenient to the Ring knife chucking and take out, distance between the tangent plane of the lower surface of described straight knife body portion and finger ring part upper end is 4~6mm, when being clamped on Ring knife on the adhesive tape, strain partly takes place in the finger ring shape, can guarantee firm being clamped on the adhesive tape of Ring knife.
