As shown in fig. 1 and 2, the utility model provides a novel fruit knife, which comprises a holding part 1, a push rod 2, a first cutting blade 3 and a second cutting blade 4. A first central hole 5 for accommodating the push rod 2 is axially arranged in the holding part 1, one end of the first central hole 5 is closed, and the other end is open. The end of the grip portion 1 adjacent the closed end of the central bore 5 is provided with a fruit blade 6, the fruit blade 6 being a conventional fruit knife which can be used to peel fruit such as apples, pears and the like. In order to prevent the sharp knife edge from exposing outside and injuring people or objects, a second central hole symmetrical to the first central hole 5 is further arranged on the holding part 1, and one end of the second central hole is closed and the other end of the second central hole is opened. A moving rod 13 is arranged in the second central hole, one end of the moving rod 13 is connected with the fruit blade 6, and the other end of the moving rod 13 is in contact connection with the closed end of the second central hole. In order to facilitate the hidden storage of the fruit blade 6, a groove for storing the fruit blade 6 is arranged on the cross section of the holding part 1 along the length direction of the holding part 1. The moving rod 13 is further provided with a second push handle 14, and the grip portion 1 is correspondingly provided with a second guide groove 15 communicating with the second center hole, and the second push handle 14 extends out of the second guide groove 15. When the fruit blade 6 is needed to be used for peeling, the second pushing handle 14 is pushed towards the direction close to the opening end of the second central hole, the second pushing handle 14 drives the moving rod 13 to move outwards, so that the fruit blade 6 at the end side of the moving rod 13 extends out of the groove and can be used for cutting fruit; when the fruit knife is not needed to be used, the second pushing handle 14 is pushed towards the direction close to the closed end of the second central hole, the second pushing handle 14 drives the moving rod 13 to move inwards, and then the fruit knife 6 is retracted into the groove, so that dangerous things can be prevented. Furthermore, in order to avoid slipping of the grip 1 when holding it in hand during use, the grip 1 is provided with a plurality of anti-slip protrusions on its surface. The other end of the holding part 1 (i.e. the opening end of the central hole) is provided with a fixed seat 7. One end of the push rod 2 extends into the first central hole 5 and is in contact connection with the closed end of the first central hole 5, and the other end of the push rod 2 extends out of the open end of the first central hole 5. A connecting rod 7 is vertically arranged on the push rod 2, and two ends of the connecting rod 7 are respectively provided with a pulley.

The first cutting insert 3 and the second cutting insert 4 are arranged facing away from each other and the end sides of the first cutting insert 3 and the second cutting insert 4 remote from the open end of the first central hole are each hinged on a holder 7. A first sliding groove is arranged on the edge of the first cutting blade 3 close to the second cutting blade 4, a second sliding groove is arranged on the edge of the second cutting blade 4 close to the first cutting blade 3, and pulleys at two ends of the connecting rod 8 are correspondingly connected in the first sliding groove and the second sliding groove in a sliding mode respectively. The push rod 2 is pushed to the direction far away from the closed end of the first central hole, the push rod 2 pushes the connecting rod 8 on the push rod to move in the direction far away from the opening end of the first central hole 5 in the sliding groove, and the first cutting blade 3 and the second cutting blade 4 are opened outwards under the action of the connecting rod 8, so that peels of shaddocks and the like are cut. In order to improve the cutting action, the first cutting insert 3 and the second cutting insert 4 are each provided with an oval shape. In addition, in order to facilitate pushing the push rod 2 when peeling, a first push handle 9 facilitating the push is provided on the push rod 2, a first guide groove 10 communicating with the first center hole 5 is provided on the grip portion 1 along the length direction thereof, and the first push handle 9 is protruded from the first guide groove 10 and moved in the first guide groove 10. Therefore, when the fruit is cut, the push rod 1 can be conveniently pushed only by pushing the first push handle 9, when the first push handle 9 is pushed, the first push handle 9 moves in the first guide groove 10, and the first guide groove 10 plays a guiding role in the first push handle, so that the push rod 2 can move more smoothly.

In another preferred embodiment, fig. 3, the first central hole 5 is further provided with an elastic reset device for resetting the push rod 2. The elastic reset device comprises a spring 11 and a baffle 12. One end of the spring 11 is fixedly connected with the baffle 12, and the other end of the spring 11 is connected with the inner wall of the holding part 1 close to the opening end of the first central hole 5. A through hole is arranged at the center of the baffle plate 12, and the push rod 1 is arranged in the through hole in a penetrating way and is fixedly connected with the baffle plate 12. When the push rod 2 is pushed towards the direction close to the opening end of the central hole 5, the baffle plate 12 fixedly connected with the push rod 2 also moves towards the direction close to the opening end of the first central hole 5, and then the spring 11 is compressed; after the cutting is finished, the push rod 2 is released, and the push rod 2 is returned to the initial position by the spring 11, and the first cutting blade 3 and the second cutting blade 4 are also returned to the initial position.

Use the utility model discloses a novel fruit knife when shelling orange or shaddock skin, to being close to second centre bore open end direction promotion second push handle 14, fruit blade 6 that links to each other with carriage release lever 13 stretches out from the recess, reuse fruit blade 6 cuts the end of orange or shaddock, then the one end that is provided with first cutting blade 3 and second cutting blade 4 on will gripping portion 1 inserts to the peel in, thereby promote push rod 2 and connecting rod 8 to being close to first centre bore open end direction again, thereby prop open first cutting blade 3 and second cutting blade 4, and then part peel and pulp, move forward gripping portion 1 again, repeated above-mentioned action, thereby make first cutting blade 3 and second cutting blade 4 cut whole fruit, separate pulp until the peel with whole fruit.

While the embodiments of the invention have been described above, it is not intended to be limited to the details shown, or described, but rather to cover all modifications, which would come within the scope of the appended claims, and all changes which come within the meaning and range of equivalency of the art are therefore intended to be embraced therein.
