Description

Cutter fixing seat, knife sharpening device and cutter set

Technical Field

The utility model relates to the technical field of knife sharpeners, in particular to a knife fixing seat, a knife sharpening device comprising the knife fixing seat and a knife set comprising the knife sharpening device.

Background

The cutter is one of the common cooking appliances in daily life and is used for processing food materials; the knife edge is used as the most critical part of the knife, and becomes blunt after a period of use, so that the cutting effect on food is affected, and therefore, the knife edge of the knife is usually ground by a knife sharpener after the knife is used for a period of time, so that the knife edge becomes sharp.

However, the conventional knife sharpener has the following disadvantages: when the knife edge of the knife is ground, the knife sharpener is usually placed on a table top, then a user holds the knife by hand and makes the knife edge of the knife aimed at the sharpening part of the knife sharpener in a certain angle range to push and pull back and forth, so that the sharpening part of the knife sharpener grinds the knife edge of the knife and the knife edge becomes sharp; in the process that the blade is grinded, as the cutter is held by a user, the angle between the blade and the sharpening part of the sharpener is easy to change at any time due to the fact that the cutter is pushed and pulled by the user, and in the process that the blade is grinded, the blade is easy to deform irregularly due to uneven stress and/or the change of the grinding angle of the blade at any time in the grinding process due to the fact that the hand of the user can shake back and forth, so that the sharpening effect is greatly reduced, and the sharpness of the blade after grinding is poor.

As shown in fig. 1, in order to solve the above-mentioned problems, a new knife sharpening device 9 is proposed in the market, and the knife sharpening device 9 includes a knife sharpener 91 and a knife holder 92.

When the knife sharpening device 9 grinds the blade of the knife 90, the knife fixing seat 92 is placed on the table, the knife 90 is abutted against the corresponding one of the side surfaces 921 according to the grinding requirement, the magnetic attraction piece 922 on the side surface 921 is used for adsorbing and fixing the knife 90, and then the knife sharpening piece 911 of the knife sharpener 91 is abutted against the blade of the knife 90, and the knife sharpener 91 is controlled to roll back and forth along the blade on the table, so that the knife sharpening piece 911 on the knife sharpener 91 grinds the blade of the knife 90 and sharpens the blade. However, the novel knife sharpening device 9 has the following defects:

the adjustable grinding angle of the cutter 90 (i.e. the inclination angle of the cutter in the grinding process) is limited, and a corresponding inclined side 921 needs to be machined on the cutter fixing seat 92 according to each different cutter grinding angle, so that the machining cost of the cutter fixing seat 92 is high, and the machining difficulty is high; in addition, on the premise that the cutter 90 can be reliably fixed in the process, when the cutter fixing seat 92 has more inclined side surfaces 921, the cutter fixing seat 92 has larger volume and is less easy to carry.

In addition, in the first direction, a third distance L3 is provided between the top side of the inclined side surface 511 and the adjustment bolt 541, and a fourth distance L4 is provided between the bottom side of the inclined side surface 511 and the adjustment bolt 541, the third distance L3 being smaller than the fourth distance L4.

When the edge of the tool 502 needs to be ground, the tool holder 5 is placed on the table surface so that the second anti-slip foot 521 of the second seat 52 contacts the table surface. Then, the inclination angle of the inclined side 511 of the first seat 51 is adjusted by the adjusting module 54, for example, the end cap 542 of the adjusting module 54 is abutted against the top of the second seat 52 by the adjusting bolt 541 of the adjusting module 54, and a non-zero angle a is formed between the first seat 51 and the second seat 52, so that the inclination angle of the inclined side 511 of the first seat 51 is a non-initial inclination angle (note: when the initial inclination angle of the inclined side 511 defaults to 0 ° for the angle a between the first seat 51 and the second seat 52, the inclination angle of the inclined side 511 is the inclination angle of the tool holder 5 when the tool holder is placed on the table).

Then, the blade body of the cutter 502 is attached to the rubber pad 55 so that the magnetic attraction member attracts and fixes the cutter 502 to the rubber pad 55, thereby maintaining the blade edge of the cutter 502 at the same inclination angle as the inclined side surface 511. Wherein the cutting edge of the cutter 502 is disposed at the lower side of the first housing 51.

Next, the sharpener 501 is placed on the table and the sharpening piece of the sharpener 501 is brought into contact with the edge of the knife 502.

Next, the sharpener 501 is reciprocated along the edge of the knife 502, so that the sharpening piece of the sharpener 501 grinds the edge of the knife 502, thereby sharpening the edge of the knife 502.

It can be seen that, through the design of the tool fixing seat 5 in this embodiment, the application range of the tool fixing seat 5 can be effectively enlarged, so that the tool fixing seat 5 can be applicable to both the tool 502 with a narrow blade and the tool 502 with a wide blade.
