[0031] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the scheme of the utility model will be further described below. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0032] In the description, it should be noted that the terms "first" and "second" are only used for descriptive purposes and should not be understood as indicating or implying relative importance. It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two elements. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0034] The specific embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0035] Reference Figure 1 The present embodiment provides a kitchen knife with a telescopic folding handle, comprising a blade body 1 and a handle 2.

[0036] A blade 12 is provided at the bottom of the blade body 1 .

[0037] Specifically, the blade 12 can be integrally forged on the blade body 1, or can be a steel-clamped blade structure, or can be detachably fixed to the blade body 1 via a connecting component.

[0038] Among them, refer to Figures 1 to 3 The handle 2 is connected to the rear side of the blade body 1, and the handle 2 includes a rotating handle 21 and a telescopic handle 22; one end of the rotating handle 21 is hinged on the blade body 1 and a first embedding groove adapted to the blade 12 is opened at the bottom, and the rotating handle 21 has a handle state unfolded on the rear side of the blade body 1 and a folded state where the first embedding groove is wrapped around the outer side of the blade 12. A first locking piece 23 is provided between the rotating handle 21 and the blade body 1 to achieve relative fixation of the two when the rotating handle 21 is in the handle state; the telescopic handle 22 is slidably sleeved A second embedding groove adapted to the blade 12 is provided on the bottom of the rotating knife handle 21. The telescopic knife handle 22 has at least a first gear and a second gear by sliding. When the telescopic knife handle 22 is in the first gear, it is used together with the rotating knife handle 21 in the knife handle state as a knife handle. When the telescopic knife handle 22 is in the second gear, it is used together with the rotating knife handle 21 in the folded state to wrap the knife blade 12. A second locking piece 24 is provided between the telescopic knife handle 22 and the rotating knife handle 21 to achieve relative fixation of the two when the telescopic knife handle 22 is in the two gears. When in use, the telescopic knife handle 22 is first adjusted to the second gear and fixed by the second locking piece 24, so that the total length of the first embedding groove and the second embedding groove after superposition matches the knife blade 12, and then the first locking piece 23 is loosened, and the knife handle 2 is rotated 180° as a whole, so that the first embedding groove and the second embedding groove are wrapped around the outside of the knife blade 12. The telescopic folding knife handle 2 adopted in the present embodiment can be adjusted to a folded state when the knife is not in use. On the one hand, it can avoid damage and accidental injury to the blade 12 caused by exposure of the blade 12, and on the other hand, it can shorten the overall length of the knife for easy storage.

[0039] It should be noted that when the rotating knife handle 21 is in the handle state, the rotating knife handle 21 and the blade body 1 can be kept relatively fixed by the pre-tightening force at the hinge of the rotating knife handle 21 and the blade body 1, so as to prevent the rotating knife handle 21 from falling off the blade body 1 when in the folded state. Of course, a locking structure such as a top screw can be used to further fix the rotating knife handle 21 and the blade body 1 in the folded state.

[0040] Specifically, the rotating blade handle 21 and the telescopic blade handle 22 are both inverted U-shaped frame structures, the telescopic blade handle 22 is slidably sleeved on the outer side of the rotating blade handle 21, the bottom opening of the rotating blade handle 21 forms a first embedding groove, and the bottom opening of the telescopic blade handle 22 forms a second embedding groove. Of course, the telescopic blade handle 22 can also be slidably sleeved on the inner side of the rotating blade handle 21, and the rotating blade handle 21 and the telescopic blade handle 22 can also adopt a plate-like structure and be connected by a slide rail.

[0041] More specifically, see Figure 4 A notch 211 is provided at the top of the rotating knife handle 21, and a slot 11 is provided at the top of the rear end of the blade body 1. The first locking member 23 includes a first lever 231 and a first elastic member 232. The fulcrum of the first lever 231 is connected in the rotating knife handle 21. A block 2311 is provided at the bottom of the front end of the first lever 231. The block 2311 cooperates with the slot 11 to achieve relative fixation of the rotating knife handle 21 and the blade body 1. The rear end of the first lever 231 is connected to the rotating knife handle 21 through the first elastic member 232. The first elastic member 232 is used to drive the rear end of the first lever 231 to move upward, and the rear end of the first lever 231 is exposed to the rotating knife handle 21 through the notch 211. When the rotating knife handle 21 is in the knife handle state, the first elastic member 232 drives the rear end of the first lever 231 to move upward, so that the front end of the first lever 231 moves downward, and then the block 2311 is tightly clamped into the clamping slot 11 to complete the matching; when in use, the rear end of the first lever 231 is pressed downward, so that the front end of the first lever 231 moves upward, so that the block 2311 is separated from the clamping slot 11, and then the rotating knife handle 21 is decoupled from the blade body 1, and the rotating knife handle 21 is in a state of being able to rotate freely. The first elastic member 232 can be a structure with elastic reset function such as a spring.

[0042] It should be noted that when the telescopic handle 22 is in the first gear, the notch 211 is covered by the telescopic handle 22, and the rear end of the first lever 231 is hidden in the telescopic handle 22, so the rotating handle 21 cannot be folded. In this way, the rotating handle 21 can always be kept in the handle state when the knife is in use, thereby ensuring safe use.

[0043] Details, see Figure 5 and Figure 6The rotary knife handle 21 is provided with two positioning holes 212 spaced apart in the front-to-back direction. The second locking member 24 includes a second lever 241 and a second elastic member 242. The fulcrum of the second lever 241 is connected to the outside of the telescopic knife handle 22. The front end of the second lever 241 is exposed to the telescopic knife handle 22. The rear end of the second lever 241 is provided with a positioning block 2411 penetrating the telescopic knife handle 22. The second elastic member 242 is connected between the second lever 241 and the telescopic knife handle 22 and is used to drive the positioning block 2411 to insert into the positioning hole 212. When the telescopic knife handle 22 is in the first gear or the second gear, the second elastic member 242 drives the positioning block 2411 to move inward to tightly fit into the positioning hole 212 to fix the telescopic knife handle 22 relative to the rotary knife handle 21. When in use, the front end of the second lever 241 is pressed inwardly to move the rear end of the second lever 241 outwardly, so that the positioning block 2411 is disengaged from the positioning hole 212 of the rotating handle 21, thereby achieving the decoupling of the rotating handle 21 and the telescopic handle 22, and the telescopic handle 22 is in a state of being able to freely retract. The second elastic member 242 can be a structure with an elastic reset function such as a spring.

[0044] Further, see Figures 6 to 9 A limiting structure 25 is also provided between the rotating tool handle 21 and the telescopic tool handle 22. The limiting structure 25 includes an elastic limiting pin 251. The elastic limiting pin 251 is installed on the rotating tool handle 21. The elastic limiting pin 251 has a limiting state protruding from the outside of the rotating tool handle 21 and an avoidance state retracted inside the rotating tool handle 21. In the free state, the elastic limiting pin 251 remains in the limiting state. The telescopic tool handle 22 is provided with a limiting hole adapted to the elastic limiting pin 251. The telescopic tool handle 22 can slide to align the elastic limiting pin 251 and insert it into the limiting hole to achieve overextension limiting. When the telescopic knife handle 22 is moved backward, the elastic limit pin 251 is inserted into the limit hole to play a limiting role, thereby preventing the telescopic knife handle 22 from being over-stretched, and further preventing the telescopic knife handle 22 from falling off the rotating knife handle 21 when being pulled; when the telescopic knife handle 22 needs to be removed for cleaning, the elastic limit pin 251 is pressed inward to switch the elastic limit pin 251 to the avoidance state, and the telescopic knife handle 22 is pulled backward while keeping the pressing posture unchanged to complete the removal of the telescopic knife handle 22; when the telescopic knife handle 22 is installed, the elastic limit pin 251 is first pressed so that the telescopic knife handle 22 can be sleeved on the rotating knife handle 21, and then the telescopic knife handle 22 is pushed forward. When the elastic limit pin 251 is inserted into the limit hole, the elastic limit pin 251 is pressed again to switch it to the avoidance state, and then the telescopic knife handle 22 is continued to be pushed forward until it moves into place.

[0045] Specifically, the limiting hole is a strip hole 221 arranged along the front-back direction, and a blocking piece 222 is convexly provided on the outer wall of the telescopic knife handle 22. The blocking piece 222 covers the rear part of the strip hole 221 and is used to guide the elastic limiting pin 251 to be gradually compressed inward. When installing the telescopic knife handle 22, after the elastic limiting pin 251 is inserted into the limiting hole, as the telescopic knife handle 22 continues to move forward, the blocking piece 222 will drive the elastic limiting pin 251 to be gradually compressed inward until it switches to the avoidance state, so that the switching of the elastic limiting pin 251 can be automatically completed, and the operation is more convenient. The blocking piece 222 can be designed as an inclined surface or a curved surface to guide the elastic limiting pin 251 to be gradually compressed inward.

[0046] More specifically, see Figure 6 The knife handle 2 also includes a protective plate 26, which is provided with two and respectively fixed on the outer sides of the two wings of the telescopic knife handle 22. The limiting structure 25 also includes an elastic pressing pin 252, which is provided on the protective plate 26 corresponding to the limiting hole and is provided at the front of the corresponding strip hole 221. The elastic pressing pin 252 is exposed on the protective plate 26, and the elastic pressing pin 252 is used to realize the switching of the elastic limiting pin 251 between the limiting state and the avoidance state by pressing. The protective plate 26 can improve the appearance quality of the knife and also improve the comfort of hand holding; the state switching of the elastic limiting pin 251 is controlled by the elastic pressing pin 252, and no external tools are needed, so the operation is more convenient.

[0047] It is easy to understand that, since the rotating blade handle 21 and the telescopic blade handle 22 are both inverted U-shaped frame structures, the rotating blade handle 21 and the telescopic blade handle 22 both have two wings and a belly.

[0048] Specifically, the protection plate 26 can be made of wood, plastic, silica gel or other common materials.

[0049] Further, see Figure 6 and Fig.10 The rear end of the telescopic knife handle 22 is provided with an end cover 27, and the front side of the end cover 27 is provided with a limiting support block 271 suitable for limiting the blade 12 when the knife handle 2 is folded. The end cover 27 can play a limiting role when the telescopic knife handle 22 is pushed forward, and can also improve the appearance quality of the knife; the limiting support block 271 can limit the blade 12 when the knife handle 2 is folded, so as to prevent the front end of the blade 12 from extending too deeply into the second embedding groove, causing damage to the internal structure of the knife handle 2.

[0050] The working principle of the telescopic folding handle kitchen knife of this embodiment is as follows:

[0051] When using the knife daily, adjust the rotating knife handle to the knife handle state, and adjust the telescopic knife handle to the first gear; when storing the knife, adjust the telescopic knife handle to the second gear, and then adjust the rotating knife handle to the folded state; when cleaning the knife, remove the telescopic knife handle from the rotating knife handle.

[0052] The above is only a specific implementation of the utility model, which enables those skilled in the art to understand or implement the utility model. Although detailed descriptions are given with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments, and they should all be covered by the protection scope of the claims.
