A limiting mounting groove 902 is provided, and a baffle 11 is installed at one end of the limiting mounting groove 902. The guide plate 7 is provided with heat dissipation holes 701. There are six heat dissipation holes 701 arranged sequentially inside the guide plate 7. A chain 8 is installed around the outside of the guide plate 7. The protective plate 9 installed thereon can provide the electric chainsaw with a good protective effect and improve the safety of the electric chainsaw. It should be noted that, in order to save space and highlight the innovative elements of this patent, such as the specific working force of the electric chainsaw, it will not be described in detail in this patent.

[0030] See Figure 1 The rear handle 2 is integrated with the old chainsaw body 1. The rear handle 2 has a trigger 3 inside. The front handle 4 is glued to the old chainsaw body 1. One end of the outer wall of the front handle 4 has friction stripes 401. Several friction stripes 401 are arranged sequentially on one end of the outer wall of the front handle 4. The installation of the rear handle 2 and the front handle 4 makes it easy to pick up and use the chainsaw. The friction stripes 401 can increase the friction between the hand and the front handle 4, making it less likely for the hand to fall off the front handle 4, thus preventing potential dangers during the use of the chainsaw.

[0031] See Figure 1 , Figure 2 , Figure 3 and Figure 4One end of the protective plate 9 is provided with a connecting seat 901, which is an integral structure with the protective plate 9. The connecting seat 901 is rotatably connected to the rotating mounting seat 5. The upper end of the protective plate 9 is provided with a handle 10, which is an integral structure with the protective plate 9. The protective groove 903 is provided correspondingly to the chain 8. The baffle 11 is provided with a fixing screw hole 1102 inside. The lower end of the baffle 11 is provided with a limiting bracket 1101 corresponding to the limiting mounting groove 902. The limiting bracket 1101 is an integral structure with the baffle 11. The baffle 11 and the protective plate 9 are connected. The protective plate 9 is fixedly connected by the fixing screw 12 and rotated to the rotating mounting base 5 via the connecting seat 901, allowing the protective plate 9 to rotate. This rotation of the protective plate 9 prevents sawdust from flying towards the face and potentially harming the worker. The installed baffle 11 further enhances the protective effect. When the chainsaw is not in use, rotating the protective plate 9 allows the chain 8 to be positioned inside the protective groove 903, protecting the chain and preventing damage during storage.

[0032] Working principle: During use, the protective plate 9 is rotated relative to the rotating mounting base 5 by rotating the handle 10. When the appropriate angle is reached, the locking knob 6 is tightened to fix the protective plate 9 and the rotating mounting base 5. When the electric chainsaw is working, wood chips will fly. The installed protective plate 9 and baffle 11 can effectively protect the user from the flying wood chips. When the wood chips fly towards the face, they can be blocked by the protective plate 9 and baffle 11, thus protecting the worker. When the electric chainsaw is placed, the chain 8 is further protected by placing one end of the chain 8 inside the limiting mounting groove 902 set in the protective plate 9. The friction stripes 401 set on one end of the outer wall of the front handle 4 can improve the friction effect between the hand and the front handle 4, thus avoiding slippage and the risk of slippage.
