Detailed Description

The utility model is further described below with reference to embodiments shown in the drawings in which:

example 1

As shown in fig. 1-9, an art designing knife comprises a shell 2 provided with a containing cavity 1 and a blade 3 capable of retracting into the containing cavity 1, wherein the shell 2 comprises a first shell 19 and a second shell 20, the containing cavity 1 is formed after the first shell 19 and the second shell 20 are spliced, and the first shell 19 and the second shell 20 are detachably connected. Four bolts 4 are fixedly arranged on the first shell 19, four jacks 5 corresponding to the bolts 4 one by one are arranged on the second shell 20, the bolts 4 are inserted into the corresponding jacks 5, and the bolts 4 are in interference fit with the corresponding jacks 5.

The accommodating cavity 1 is internally provided with a sliding frame 6, the sliding frame 6 is provided with a chute 7 which is inclined relative to the sliding direction of the sliding frame 6, and the angle between the length direction of the chute 7 and the sliding direction of the sliding frame 6 is 45 degrees. The blade 3 is mounted on the carriage 6 and the blade 3 and the carriage 6 are slidably arranged together in the receiving chamber 1.

The first shell 19 is provided with a mounting groove 8, the bottom of the mounting groove 8 is provided with a central hole 9 and an arc groove 10 surrounding the central hole 9, a knob 11 is arranged in the mounting groove 8, a rotating piece 12 rotatably arranged in the central hole 9 and a rotating pin 13 extending into the chute 7 are fixedly connected to the knob 11, and the rotating pin 13 penetrates through the arc groove 10 and extends into the chute 7. The outer side surface of the knob 11 is fixedly connected with a poking block 14. The knob 11 can be turned conveniently when the utility knife is used by the poking block 14. The rotary pin 13 can drive the sliding frame 6 to drive the blade 3 to slide along with the rotation of the knob 11, so that the blade 3 is retracted into the accommodating cavity 1 and extended out of the accommodating cavity 1. Two mutually parallel limiting strips 15 are fixedly arranged on the sliding frame 6, a positioning block 16 fixed on the sliding frame 6 is arranged between the two limiting strips 15, the blade 3 is positioned between the two limiting strips 15, the blade 3 is attached to the sliding frame 6, a positioning hole 17 is formed in the blade 3, and the positioning block 16 is embedded into the positioning hole 17; the blade 3 is attached to the first housing 19, and the carriage 6 is attached to the second housing 20.

The housing 2 is provided with a through hole 18 penetrating the housing 2. The art designing knife can be hung and placed by penetrating through components such as a hanging rope at the position of the through hole 18, or can be directly hung on a hook at the position of the through hole 18 for placing the art designing knife.

The application principle of the utility model is as follows:

when the blade 3 of the utility knife is positioned in the accommodating cavity 1 in the shell 2, the rotary pin 13 on the rotary knob 11 is positioned at the end part of the chute 7 close to the outer end of the blade 3, at the moment, the rotary knob 11 is rotated anticlockwise, the rotary pin 13 pushes the sliding frame 6 to slide towards the outer end of the accommodating cavity 1 along with the rotation of the rotary knob 11, the sliding frame 6 drives the blade 3 to move along the outer end of the accommodating cavity 1, when the rotary knob 11 rotates 180 degrees, the rotary pin 13 is positioned at the other end of the chute 7, at the moment, one end of the blade 3 extends out of the accommodating cavity 1, and at the moment, the blade 3 can be used. When the blade 3 is required to be retracted into the accommodating cavity 1, the knob 11 is reversely rotated. When the knob 11 is collided by external force, the knob 11 and the first housing 19 generally do not rotate relatively or rotate relatively by a small angle, when the rotation angle of the knob 11 is small, for example, smaller than 10 degrees, the sliding distance between the sliding frame 6 and the blade 3 pushed by the rotating pin 13 is extremely small, and a certain interval is generally reserved between the outer end of the blade 3 and the outer end of the accommodating cavity 1 when the blade 3 is accommodated in the accommodating cavity 1, so that the outer end of the blade 3 does not extend out of the accommodating cavity 1 when the sliding distance of the blade 3 is small, and the blade 3 is prevented from scratching a user. Even if the outer end of the blade 3 is not spaced from the outer end of the accommodating cavity 1 when the blade 3 is accommodated in the accommodating cavity 1, the length of the blade 3 extending out of the accommodating cavity 1 is shorter when the sliding distance of the blade 3 is smaller, and the scratch degree to a user can be reduced, so that the safety performance of the push-pull type art designing knife is better than that of the conventional push-pull type art designing knife.

In the utility model, the blade 3 is arranged on the sliding frame 6, the chute 7 is arranged on the sliding frame 6 to be matched with the rotary pin 13, instead of directly arranging the chute 7 on the blade 3, because the longer chute 7 can cause larger influence on the structural strength of the blade 3 and can reduce the structural strength of the blade 3, thereby generating other potential safety hazards, and the chute 7 is arranged on the sliding frame 6 and is provided with smaller positioning holes 17 on the blade 3, so that the influence on the structural strength of the blade 3 is smaller. By separating the first housing 19 and the second housing 20, the blade 3 can be replaced with a new one, and the operation is convenient.

It should be understood that in the claims, the specification of the present utility model, all "including … …" should be interpreted as open-ended meaning that it is equivalent to "at least … …", and not as closed-ended meaning that it should not be interpreted to "include … …" only.
