Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following specific examples.

As shown in fig. 1-5, a mouse-shaped cutter comprises a shell 1, a circular blade 2, a central shaft 12, a lifting button 3 and an elastic piece 4, a containing cavity 13 for containing the circular blade 2 is arranged inside the shell 1, a notch 14 for exposing the circular blade 2 is arranged outside the shell 1, the central shaft 12 is fixed in the cavity 13, the circular blade 2 comprises a mounting hole 21, the circular blade 2 is rotatably sleeved on the central shaft 12, a plurality of limiting grooves 22 are annularly arranged on the outer periphery of the mounting hole 21 on the upper surface of the circular blade 2, the upper surface of the shell 1 is provided with a yielding hole 11 corresponding to the central shaft 12, the lifting button 3 penetrates the yielding hole 11 to be in sliding fit with the central shaft 12, the lower surface of the lifting button 3 is provided with a limiting convex column 31 matched with the limiting groove 22, and two ends of the elastic piece 4 are respectively connected with the lifting button 3 and the central shaft 12.

When the cutting tool is used, the lifting button 3 is only required to be pressed down lightly, the limiting convex column 31 on the lower surface of the lifting button 3 is inserted into the limiting groove 22 on the circular blade 2, so that the circular blade 2 can be locked, the circular blade 2 can not rotate, and at the moment, some articles can be cut by the cutting tool. When the lifting button 3 is loosened, the limiting convex column 31 leaves the limiting groove 22, the locking of the circular blade 2 is released, and the circular blade 2 can rotate, so that a user can rotate the worn blade face to other angles to replace the unworn blade face. Have twelve spacing grooves 22 in this embodiment at least, sufficient spacing groove 22 can contract the angle of rotation at every turn of small circular blade 2, is convenient for adjust the change knife face, realizes the knife face of the whole circular blade 2 of make full use of. The hand can not directly contact with the blade in the whole operation process, and the blade is effectively prevented from being accidentally injured, so that potential safety hazards are eliminated.

Preferably, the inside holding tank 32 that is equipped with of lifting button 3, holding tank 32 and the upper end of center pin 12 just set up and the notch is down, and the inner groove wall of holding tank 32 is equipped with along the guide rail 321 that extends from top to bottom, center pin 12 upper end be equipped with stretch into holding tank 32 with guide rail 321 sliding fit's slider 121. When the lifting button 3 is pressed, the slider 121 slides up and down in the guide rail 321, the slider 121 and the guide rail 321 are matched to play a role in guiding, so that the lifting action of the lifting button 3 is more stable, and the slider 121 and the upper end of the guide rail 321 are clamped mutually, so that the lifting button 3 can be prevented from falling off from the central shaft 12.

In this embodiment, elastic component 4 is the spring, the spring is established holding tank 32 middle part and the spring extends along upper and lower direction, specifically can be the pressure spring, and under the spring natural state, lift button 3 is located the highest horizontal position, and spacing projection 31 stretches out spacing groove 22, and the spring is compressed the back, and lift button 3 is located lowest horizontal position, and spacing projection 31 stretches into spacing groove 22. Because the spring is simple in structure and convenient and fast to install, the production efficiency can be improved, and the production cost can be reduced.

Preferably, the plurality of limiting convex columns 31 correspond to the limiting grooves 22 one by one. Set up the spacing projection 31 of a plurality of and spacing groove 22 one-to-one, can be more favorable to locking circular blade 2 fast, prevent that spacing projection 31 from because exerting oneself too big and fracture, because on a plurality of spacing projections 31 can be with the stress decomposition to every spacing projection 31 that receives, the stress that single spacing projection 31 received will be very little like this, can prevent that spacing projection 31 from splitting.

Preferably, the housing 1 has a circular shape, and the central shaft 12 is disposed at a center of the housing 1. The central shaft 12 is arranged at the center of the housing 1, so that the circular blade 2 can rotate more smoothly without being blocked by the housing 1.

As shown in fig. 1, two ring bodies 6 are symmetrically connected to the outside of the housing 1, and the two ring bodies 6 are disposed opposite to the notch 14. The two ring bodies 6 can fix fingers, so that a user can use the ring more stably. In addition, when the cutter is not needed to be used, the two ring bodies 6 can be used as hanging rings to hang the cutter, and therefore the occupied space is avoided. The two ring bodies 6 are combined with the circular shell, so that the appearance of the whole cutter is similar to that of a mouse, the two ring bodies 6 are like two ears of the mouse, the lifting button 3 is like the nose of the mouse, and the gap 14 is like the mouth of the mouse, so that the appearance shape is enriched, and the cutter is convenient to carry.

In this embodiment, the protective cover 5 is matched with the notch 14. When the knife is not needed, the knife face can be covered by the protective cover 5, and the user is prevented from being accidentally injured by carelessness. The matching mode between the protective cover 5 and the casing 1 can refer to the matching mode between the pen cover and the pen casing.

The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications thereof by those skilled in the art should be considered as not departing from the scope of the present invention.
