When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0032] In the description of the present utility model, it should be noted that the terms "center", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the utility model product is usually placed when in use, and are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third" and the like are only used to distinguish descriptions, and cannot be understood as indicating or implying relative importance. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined. The meaning of "several" is one or more, unless otherwise clearly and specifically defined.

[0033] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" 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; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the scope of the utility model. In addition, in the following description, the description of the known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0035] Example 1: See Figure 1 , Figure 2 , Figure 3 and Figure 4The cam 3 is provided with a plurality of protruding teeth 11 and a plurality of cam 32, wherein the cam 3 is provided with a plurality of protruding teeth 12 and a plurality of cam 33. The cam 3 is provided with a plurality of protruding teeth 11 and a plurality of cam 33. The cam 3 is provided with a plurality of protruding teeth 12 and a plurality of cam 33. The cam 3 is provided with a plurality of protruding teeth 12 and a plurality of cam 33.

[0036] Embodiment 2: It can be explained on the basis of embodiment 1, such as Figure 5 and Figure 6 As shown, the connection assembly 4 includes connection pieces 41 arranged on both sides of the welding base 1 and the transmission piece 2, and the two ends of each connection piece 41 are connected to the welding base 1 and the transmission piece 2 by rivets 42, respectively. This arrangement is reasonable and easy to implement. In order to improve the stability of the connection, sealing rings 43 are arranged on both ends of the rivet 42, wherein the sealing ring 43 is an O-ring made of fluororubber, which is easy to implement. It should be noted that reinforcing ribs 44 are arranged on the connection piece 41, which is not only conducive to convenient identification of the front and back sides and easy installation on both sides of the welding base 1 and the transmission piece 2, but also conducive to enhancing the bending strength of the connection piece 41.

[0037] Embodiment 3: It can be explained on the basis of embodiment 2, such as Figure 7 , Figure 8 and Fig. 9 As shown, the anti-collision member 5 includes an anti-collision portion 51 and a mounting portion 52 (and in this embodiment, the mounting portion 52 is horizontal) provided on the connecting piece 41. The mounting portions 52 adjacent to the connecting pieces 41 in the length direction form a groove for mounting the cutting knife 3. The grooves between the corresponding adjacent connecting pieces 41 form a mounting groove for mounting the cutting knife 3. Both ends of the mounting groove are the anti-collision portions 51. This is more conducive to meeting the requirements of fixing the cutting knife 3 after installation, avoiding all of them being concentrated on the welding base 1, reducing the occurrence of damage or damage caused by all of them being concentrated together, and making double support points to reduce the direct collision of the cutting object with the cutting knife 3 during the use of the chain. With the anti-collision portion 51 on the connecting piece 41, the cutting object will not get stuck in the chain and directly hit the cutting knife 3, which is more conducive to meeting the use requirements.

[0038] Embodiment 4: It can be described on the basis of Embodiment 1 or Embodiment 2, such as Fig.10 and Fig.11 As shown, the anti-collision member 5 includes an anti-collision tooth 53 arranged on the transmission plate 2, and the anti-collision tooth 53 is integrally formed with the transmission plate 2. Since the welding base 1 and the transmission plate 2 are alternately distributed, the anti-collision teeth 53 are distributed on both sides of the cutting knife 3. This not only prevents the cutting object from getting stuck in the chain and directly hitting the cutting knife 3, but also greatly improves the strength of the transmission plate 2.

[0039] Embodiment 5: It can be described on the basis of Embodiment 1 or Embodiment 2 or Embodiment 3 or Embodiment 4, that the cutting blade 3 is made of diamond, which has a higher hardness and is more conducive to cutting.

[0040] The standard parts used in this application document can all be purchased from the market, and the specific connection methods of each part adopt conventional means such as mature bolts and rivets in the prior art, which will not be described in detail here.

[0041] It should be noted that although the above embodiments have been described in this article, this does not limit the scope of patent protection of the utility model. Therefore, based on the innovative concept of the utility model, changes and modifications to the embodiments described in this article, or equivalent structural or equivalent process changes made using the contents of the utility model specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields are all included in the scope of protection of the utility model patent.
