Description

Technical Field

[0001] This utility model relates to an adjustable dual-purpose knife for peeling and cutting vegetables. Background Technology

[0002] Existing peelers have a fixed blade angle, which cannot be adjusted arbitrarily during peeling, making them inconvenient to use when peeling fruits or vegetables of different thicknesses. Therefore, some have designed peelers with adjustable blade angles suitable for cutting fruits or vegetables of varying thicknesses. For example, Chinese patent CN2091608 discloses an adjustable peeler. However, this type of adjustable peeler has a complex structure and limited functionality. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing a simple, adjustable dual-purpose knife that can both peel and cut vegetables.

[0004] The purpose of this utility model is achieved as follows: an adjustable dual-purpose knife for peeling and cutting vegetables includes a handle, a blade, a peeling blade, and an adjusting screw. The blade has a first and a second hinge point, and the peeling blade has a third and a fourth hinge point. The peeling blade is hinged to the first and second hinge points at the third and fourth hinge points respectively via two connecting rods of equal length, forming a parallelogram-shaped four-bar linkage. By changing the angle between the connecting rods and the blade, the gap between the peeling blade and the blade is changed, thus adjusting the peeling thickness. A nut corresponding to the adjusting screw is provided on the blade; by adjusting the screw, one of the connecting rods is locked to limit its swing, thus fixing the gap between the peeling blade and the blade for use.

[0005] In this invention, the first and second hinge points are provided with hinge holes on the lugs that bend from the back of the blade.

[0006] In this invention, the third and fourth hinge points are made of tubular pin holes rolled from the edge of a peeling blade.

[0007] In this invention, one of the two equal-length connecting rods is a U-shaped connecting rod, with the rod portion and the pin portion of the U-shaped connecting rod integrally bent and formed.

[0008] This utility model has the following positive effects: by utilizing a simple four-bar hinge structure with a parallelogram shape, it can be combined with the blade to achieve two functions in one.

[0009] The following embodiments, in conjunction with the accompanying drawings, further illustrate the present invention. Attached Figure Description

[0015] In the diagram, 1 is the handle; 2 is the blade; 3 is the peeler blade; 4 is the adjusting screw; 5 is the nut; 6 is the connecting rod; 7 is the hinge hole; 8 is the U-shaped connecting rod; and 9 is the pin. Detailed Implementation

[0016] Reference Figures 1 to 5 This embodiment is an adjustable peeling and cutting knife, including a handle 1, a blade 2, a peeling blade 3, and an adjusting screw 4. The blade has a first hinge point and a second hinge point, with hinge holes 7 formed on lugs bent from the back of the blade. The peeling blade has a third hinge point and a fourth hinge point, formed by tubular pin holes rolled from the edge of the peeling blade. The peeling blade has hinge holes at the third and fourth hinge points respectively. Two equal-length connecting rods are hinged to the first and second hinge points to form a parallelogram-shaped four-bar linkage. One of the two equal-length connecting rods is a U-shaped connecting rod 8, with the rod part and the pin part 9 integrally bent. By changing the angle between the connecting rod and the blade, the gap between the peeling blade and the blade is changed, thereby adjusting the peeling thickness. Nuts 5 corresponding to the adjusting screw are provided on the blade. By adjusting the screw, one of the connecting rods 6 is locked to limit the swing, thus fixing the gap between the peeling blade and the blade for use.

[0017] This utility model, with reference to Figure 2 During assembly, the two equal-length connecting rods, i.e., the two hinges, are generally first assembled onto the peeler blade. The nut corresponding to the adjusting screw is welded to the blade body. One end of the U-shaped connecting rod is inserted into the hinge hole of the first lug, and the other connecting rod is inserted between the second lug and the nut. It is connected to the nut with the adjusting screw. In the loose state, the gap between the peeler blade and the blade body is adjusted by changing the angle between the connecting rod and the blade body, so that the peeling thickness of the peeler blade is adjusted to the required condition. Then it is locked so that the connecting rod does not swing, and the peeler blade is in a stationary state for use.
