[0020] The embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0021] Referring to Figures 1 to 3 As shown, a crab cactus grafting knife according to a preferred embodiment of the present application includes a handle 1. One end of the handle 1 along its length direction is connected with a first blade 2 and a second blade 3. The first blade 2 is in a straight shape. The second blade 3 includes a first blade body 31 and a second blade body 32. Both the first blade body 31 and the second blade body 32 are in a straight shape. One end of the second blade body 32 along its length direction is the first end and the other end is the second end. Among them, one end of the first blade body 31 along its length direction is connected with the handle 1, and the other end is connected with the first end of the second blade body 32. The first blade body 31 and the second blade body 32 are perpendicular to each other, and the second blade body 32 is arranged on the side of the first blade body 31 close to the first blade 2. One end of the first blade 2 along its length direction is connected with the handle 1, and the other end is connected with the second end of the second blade body 32. The first blade 2 intersects with the second blade body 32, and the end of the first blade 2 connected with the handle 1 is located on the side of the second end close to the first blade body 31.

[0022] Specifically, the ends of the first blade 2 and the second blade 3 far from the handle 1 enclose a wedge-shaped structure that is narrow at the top and wide at the bottom, similar to the shape of "凵". For such a crab cactus grafting knife with this structure, only a single operation is required to cut a wedge-shaped grafting opening on the scion, without multiple cutting operations, with high operation efficiency and short time consumption.

[0023] In practical applications, taking the scion as the stem of a pitaya as an example, the stem of the pitaya is in a long straight rod shape and extends upward. When using the crab cactus grafting knife of the present application to cut a grafting opening on the scion, the overall length direction of the crab cactus grafting knife intersects with the length direction of the stem of the pitaya, and the crab cactus grafting knife is arranged obliquely downward. When cutting, the crab cactus grafting knife moves horizontally to cut a grafting opening on the stem of the pitaya, with high operation efficiency and short time consumption.

[0024] Furthermore, the first blade 2 and the second blade body 32 intersect to form an included angle θ, where 85° ≤ θ < 90°. At this time, the length direction of the first blade 2 and the length direction of the first blade body 31 intersect. Thus, for the grafting opening formed on the scion, the two wall surfaces formed by the first blade 2 and the first blade body 31 also have a certain angle. At this time, when observing along the cutting direction, the grafting opening is wedge-shaped and has a suitable size. Inserting the scion into the grafting opening with such a structure is beneficial to the preliminary fixation of the scion.

[0025] In practical applications, when grafting Christmas cactus, its leaf-like stems are used as scions, which are relatively small in size. In addition, the Christmas cactus needs to be thinned during grafting to increase the contact area with the rootstock and promote callus formation. Therefore, in this embodiment, the length of the second blade 32 is 1-1.5mm. Within this range, the length of the second blade 32 can cut a grafting interface of a suitable size to facilitate the smooth progress of the grafting work.

[0026] Furthermore, the Christmas cactus grafting knife also includes a push plate 4, which is connected to one end of the first blade 31 along its width direction. The push plate 4 extends a predetermined distance toward the side where the first blade 2 is located. Specifically, the end of the first blade 31 with the push plate 4 is the rear end, and the opposite end is the front end. When the Christmas cactus grafting knife is used to cut the rootstock, the front end contacts the rootstock first. Based on this, after the cutting is completed, the push plate 4 can push the cut-off part of the rootstock directly out of the grafting interface, which is convenient to operate.

[0027] It should be noted that the depth direction is from the opening side of the grafting interface to the opposite bottom side. The bottom side is formed by the cutting of the second blade 32. Under normal circumstances, the depth of the grafting interface is 5-8mm. Therefore, the connection point between the first blade 31 and the second blade 32 is called the first connection point. Along the depth direction, the distance between the end of the push plate 4 away from the second blade 32 and the first connection point is less than 5mm, so as to ensure that the cut part of the rootstock can be pushed out smoothly.

[0028] In addition, since the depth of the grafting interface is 5-8mm, the lengths of the first blade 2 and the first blade body 31 are both greater than 8mm. The specific lengths are set according to the actual application, and this application does not impose any restrictions on them.

[0029] Furthermore, the push plate 4 extends 0.5-1mm toward the side where the first blade 2 is located. The push plate 4 meets this size range, and its structure is stable and reliable, enabling it to smoothly push the part of the rootstock that has been cut off from the grafting interface.

[0030] In this embodiment, the outer circumferential surface of the handle 1 is provided with a receiving groove 101. One end of the receiving groove 101 along the length direction of the handle 1 has an opening. The first blade 2 and the first blade body 31 are rotatably connected to the opening of the receiving groove 101. The receiving groove 101 is used to accommodate the first blade 2 and the second blade 3. Specifically, the receiving groove 101 has two openings, and the first blade 2 and the second blade 3 are rotatably connected to the two openings respectively. Based on the setting of the receiving groove 101, in practical applications, when the Christmas cactus grafting knife is idle, the first blade 2 and the second blade 3 can be rotated into the receiving groove 101, which is safe and the overall volume of the Christmas cactus grafting knife is reduced, making it easy to store.

[0031] For example, the first blade 2 and the first blade body 31 are rotatably connected to the handle 1 by a pin. This is prior art and will not be described in detail in this application.

[0032] Furthermore, such as Figure 3 As shown, the first blade 2 is connected to the second end of the second blade body 32. Thus, the Christmas cactus grafting knife can be used alone with the first blade 2 to perform some cutting work. It can be used as a conventional knife and has high adaptability.

[0033] In this embodiment, the first blade 2 and the second blade 3 are both made of stainless steel. Furthermore, the push plate 4 is also made of stainless steel. The first blade body 31, the second blade body 32 and the push plate 4 are integrally connected, with a simple structure and convenient processing. The first blade 2 and the second blade 3 made of this material have high strength and good cutting ability.

[0034] For example, the thickness of the first blade 2, the second blade 3 and the push plate 4 is 0.15-0.25 mm.

[0035] In this application, the outer peripheral surface of the handle 1 may also be provided with anti-slip texture or grooves adapted to the fingers to facilitate operation.

[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
