[0025] Please refer to Figures 1-5 A chain saw end cover comprises a main body cover 1 and a center positioning block 2. An opening groove 11 is provided on the main body cover 1, and the center positioning block 2 is installed in the opening groove 11. The opening groove 11 runs through one side of the main body cover 1. Six clamps 12 are provided along the outer periphery of the opening groove 11 of the main body cover 1, and a clamping groove 13 is provided inside the clamping member 12. Six protrusions 21 are provided on the outer periphery of the center positioning block 2. The protrusions 21 are adapted to the clamping groove 13, and the protrusions 21 can be clamped into the clamping groove 13 to form a clamping fixation; a first stopper 14 is provided on the outer side of the clamping groove 13, and a second stopper 22 is provided at the bottom of the protrusion 21. The first stopper 14 is adapted to and conflicts with the second stopper 22 to prevent the protrusion 21 from falling out of the clamping groove 13, so that the main body cover 1 and the center positioning block 2 can be well clamped and fixed together.

[0026] In this embodiment, the main body cover 1 is made of pp plastic with 30% glass fiber. The design of the glass fiber reinforced PP main body cover 1 increases the hardness and wear resistance of the product. The central positioning block 2 is made of aluminum alloy. That is, the chain saw end cover of the present application is composed of a plastic main body cover 1 and a metal central positioning block 2, which reduces the production cost while ensuring the original strength.

[0027] On both sides of the opening groove 11 of the main body cover 1, there are pressing grooves 15. On both sides of the central positioning block 2, there are pressing clasps 23. The pressing clasps 23 are adapted to the pressing grooves 15 to play an auxiliary clamping role to prevent the central positioning from falling out of the opening groove 11.

[0028] On the inner side of the opening groove 11 of the main body cover 1, there is an alignment groove 16. The clamping parts 12 are arranged on both sides of the alignment groove 16. One end of the central positioning block 2 is provided with an alignment block 24. The convex blocks 21 are arranged on both sides of the alignment block 24. The alignment block 24 is adapted to the alignment groove 16.

[0029] The clamping parts 12 and the clamping grooves 13 are in the shape of isosceles trapezoids. The convex blocks 21 are also in the shape of isosceles trapezoids. The isosceles trapezoid design makes it more difficult for the convex blocks 21 and the clamping grooves 13 to separate.

[0030] The main body cover 1 is provided with a first through hole 17 at one of its corners. The first through hole 17 plays a role in positioning and installing the chain saw adjustment mechanism. The central positioning block 2 is provided with a second through hole 25 on one of its sides. The second through hole 25 plays a role in positioning and locking. That is, the chain saw end cover can be fixed to the outside of the chain saw through fasteners, thereby protecting the internal mechanical and electronic components and extending the service life of the chain saw.

[0031] On the outer peripheral side of the first through hole 17, there is a mark 18. The mark 18 reminds the user which side to rotate to adjust the tightness of the chain.

[0032] The present utility model is a chain saw end cover, and its working principle is described in conjunction with the accompanying drawings:

[0033] The main body cover 1 and the central positioning block 2 are made by different molds. Since the main body cover 1 is made of plastic, the opening slot 11 can be slightly opened to facilitate the installation of the central positioning block 2. Align the alignment block 24 of the central positioning block 2 with the alignment slot 16 of the main body cover 1, and install the central positioning block 2 into the opening slot 11. It is fixed in the main body cover 1 through the clamping fit between the convex block 21 and the clamping groove 13 and the clamping fit between the pressing buckle 23 and the pressing groove 15. Under the action of the first anti-withdrawal portion 14 and the second anti-withdrawal portion 22, the central positioning block 2 will not easily fall out of the main body cover 1. Then, fasteners are installed in the second through hole 25 to fix the chain saw end cover. The chain saw end cover can prevent external substances, such as dust, wood chips, water, etc., from entering the chain saw interior, thereby protecting the internal mechanical and electronic components and extending the service life of the chain saw; at the same time, it can also increase the overall aesthetics of the chain saw and reduce the noise generated during the operation of the chain saw through its design.

[0034] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
