The technical problem to be solved by the utility model can be realized through the following technical solutions:

A knife, comprising a handle and a blade, characterized in that: the blade is divided into an upper blade and a lower blade, the connecting piece connects the upper blade and the lower blade, and the fixing and separation of the upper blade and the lower blade are regulated by a rotating pin and a screw rod .

The width of the upper blade is smaller than the width of the lower blade.

The thickness of the upper blade is smaller than that of the lower blade.

The connecting piece is located on both sides of the blade and is composed of a protrusion arranged on the upper blade and a groove arranged on the lower blade, the groove matches the protrusion, and the protrusion can slide in the groove.

The screw rod is welded on the end of the upper blade, and the rotating pin is sleeved on the periphery of the screw rod, and is threadedly connected with the screw rod.

The rotating pins have different lengths at both ends of the screw.

Due to the adoption of the above technical solution, the positive effect of the utility model is that the upper and lower blades are convenient to replace, and the use is safe and reliable, and has the advantages of convenient use, stability and reliability, and saving storage space.

Fig. 4 is A-A sectional view of the utility model embodiment 2.

Numbers among the figure: 1 is a handle of a knife, 2 is a blade, 21 is an upper blade, 22 is a lower blade, 3 is a connector, 31 is a protrusion, 32 is a groove, 4 is a rotating pin, and 5 is a screw rod.

Detailed ways

In order to make the technical means, creative features, goals and effects of the present utility model easy to understand, the utility model will be further elaborated below in conjunction with specific illustrations.

As shown in Fig. 1 and Fig. 2, a kind of cutting tool comprises knife handle 1 and blade 2, and described blade is divided into upper blade 21 and lower blade 22, and connecting member 3 connects upper blade 21 and lower blade 22, by rotating pin 4 and screw rod 5 regulate the fixing and separation of the upper blade 21 and the lower blade 22.

The width of the upper blade 21 is smaller than the width of the lower blade 22 . The thickness of the upper blade 21 is smaller than that of the lower blade 22 .

As shown in Figures 3 and 4, the connector 3 is located on both sides of the blade 2 and is composed of a protrusion 31 arranged on the upper blade 21 and a groove 32 arranged on the lower blade 22, the groove 32 and the protrusion 31 Matched, the protrusion 31 can slide in the groove 32 .

The screw rod 5 is welded on the end of the upper blade 21, and the rotating pin 4 is sleeved on the periphery of the screw rod 5, and is threadedly connected with the screw rod 5.

Example 1

As shown in Fig. 3, a kind of cutter comprises handle 1 and blade 2, and described blade is divided into upper blade 21 and lower blade 22, and upper blade 21 is fixed in handle 1, and the protrusion 31 of connector 3 is spherical , the groove 32 of the connector 3 is a spherical depression and matches with the protrusion 31. When the rotating pin 4 rotates around the screw rod 5 and the long end is downward, the upper blade 21 and the lower blade 22 are locked together. The utility model can be used as a kitchen knife , can cut food materials such as meat that are not easy to cut (see Figure 1). When the long end of turning pin 4 was upwards, the upper blade 21 was pulled, and the protrusion 31 of the upper blade 21 moved along the groove 32, and the lower blade 22 was separated from the upper blade 12, and only the upper blade 21 was connected with the handle 1, then it could be The fruit knife is used to cut ingredients such as fruits and vegetables (see Figure 2).

Example 2

As shown in Figure 4, a knife includes a handle 1 and a blade 2, the blade is divided into an upper blade 21 and a lower blade 22, the upper blade 21 is fixed in the handle 1, and the protrusion 31 of the connector 3 is an arrow Shape, the groove 32 of the connector 3 is a depression matching the protrusion 31, and the connection method of the connector 3 is stable and firm. When the rotating pin 4 rotates around the long end of the screw rod 5 downwards, the upper blade 21 and the lower blade 22 are locked together, and the fixing and separation of the utility model are the same as in the first embodiment.

Due to the adoption of the above technical solution, the positive effect of the utility model is that the upper and lower blades can be easily replaced, the integration of the knives is realized, the use is safe and reliable, and the utility model has the advantages of convenient use, stability and reliability, and saving storage space.

The above is one of the embodiments of the present utility model. For those skilled in the art, various changes can be made on the basis of the above-mentioned embodiments without creative labor, and the purpose of the present utility model can also be achieved. However, such changes should obviously be within the protection scope of the claims of the present utility model.
