The shape and size of the saw plate 3 are matched with the working requirements of the chain saw to ensure that the saw chain can stably run on the saw plate 3 and effectively perform cutting operations. The saw chain is an annular structure composed of a series of saw teeth and a chain. The saw teeth are made of a material with high hardness and can quickly cut materials such as wood. The saw chain is firmly and reliably mounted on the saw plate 3 to ensure that it does not loosen or fall off during operation.

[0041] The locking assembly 4 is connected to the second housing 2 through the first housing 1 and the saw plate 3. Its main function is to drive the first housing 1 and the second housing 2 to move closer to or farther away from the saw plate 3. The locking assembly 4 is usually composed of bolts, nuts and other components. The distance between the first housing 1 and the second housing 2 can be adjusted by rotating the bolts. When the tension of the saw chain needs to be adjusted, the first housing 1 and the second housing 2 can be moved relative to the saw plate 3 through the locking assembly 4, thereby changing the tension state of the saw plate 3 on the housing.

[0042] The adjustment assembly 5 is arranged between the first housing 1 and the second housing 2 and is used to drive the saw plate 3 to move along its length direction.

The limiting block 22 is arranged on the second protruding end 21 and matches the sliding hole 31 on the saw plate 3, and the limiting block 22 is arranged below the locking rod 41.

[0059] In this technical solution, the second protruding end 21 is arranged on the second shell 2, and the protruding end and the first protruding end 11 on the first shell 1 are located on both sides of the saw plate 3, thereby providing stable support and limiting for the saw plate 3 during the locking of the locking assembly 4.

[0060] The limiting block 22 is arranged on the second protruding end 21 and matches the sliding hole 31 on the saw plate 3. The limiting block 22 is usually made of high-strength metal or plastic material and has good wear resistance and stability. The limiting block 22 is arranged below the locking rod 41, and its main function is to limit the saw plate 3 during the adjustment of the saw plate 3, so that the saw plate 3 can move along its length direction, thereby adjusting the tension of the saw plate 3. At the same time, the stability of the chain saw during work is also improved, and unnecessary displacement of the saw plate 3 is avoided, so that the saw chain is not loose or too tight, thereby affecting the sawing effect and service life of the chain saw. The existence of the limiting block 22 can effectively limit the movement range of the saw plate 3, ensure that the saw chain always maintains a suitable tension state, and improve the working efficiency and stability of the chain saw.

[0061] The driving groove 23 is arranged on the second shell 2, and the driving groove 23 is used to install the chain wheel. The chain wheel is connected with the saw chain in meshing mode.

[0062] In this technical solution, the driving groove 23 is arranged on the second shell 2, and the driving groove 23 is used to install the chain wheel. After the chain wheel is installed in the driving groove 23, the chain wheel is connected with the saw chain in meshing mode. This meshing connection mode enables the chain wheel to drive the saw chain to rotate at high speed, thereby realizing the cutting of wood and other materials. By arranging the driving groove 23 on the second shell 2 to install the chain wheel, the structure of the chain saw is more compact and reasonable, and the installation and maintenance of the chain wheel are also facilitated. When the chain wheel needs to be replaced or repaired, the chain wheel can be taken out of the driving groove 23, which is simple and convenient. At the same time, the existence of the driving groove 23 also provides protection for other components of the chain saw, avoiding interference or collision between the chain wheel and other components during work.

[0063] The fixing assembly 6 further comprises:

[0068] In this technical solution, the driving hole formed on the first shell 1 provides a mounting position for the driving part 51. When the driving part 51 is mounted in the driving hole, its operating part will usually be exposed outside the first shell 1, so as to be operated by the operator. The operator can drive the driving rod 52 and the adjusting rod 53 to move by rotating the driving part 51, so as to realize the adjustment of the position of the saw plate 3, and further adjust the tension of the chain saw.

[0069] Further comprising a protective cover 7 arranged between the first shell 1 and the second shell 2.

[0070] In this technical solution, the arrangement of the protective cover 7 adds important safety protection and functionality to the use of the chain saw. The protective cover 7 is arranged between the first shell 1 and the second shell 2, and can effectively prevent the operator from being injured when the chain accidentally flies out or breaks during the operation of the chain saw. The chain has a lot of kinetic energy when it is running at high speed. Once an accident occurs, the protective cover 7 can act as a solid barrier to block the chain from splashing towards the operator. The protective cover 7 is usually made of high-strength, impact-resistant materials such as strong plastic or metal alloy, which can withstand a large impact force without breaking or deforming.

[0071] In terms of functionality, the protective cover 7 can reduce the possibility of dust, debris, and the like entering the chain saw. In the working environment of the chain saw, there are often wood chips, dust, and other impurities. If these impurities enter the chain saw, they may affect the normal operation of the chain saw, or even damage the internal parts. The presence of the protective cover 7 can block the entry of these impurities to some extent, keep the chain saw clean, and prolong the service life of the chain saw.

[0072] In addition, the design of the protective cover 7 also needs to consider the connection method with the first shell 1 and the second shell 2, and the convenience of installation and disassembly. The connection method needs to ensure that the protective cover 7 does not loosen or fall off during work, while also being easy to disassemble when maintenance or repair is needed. Buckle connection, bolt connection or other reliable connection methods can be used.
