[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figure 1-Figure 4 A single-grip lithium-ion electric chain saw includes a protective cover 2, which is generally arranged on the outside of the chain saw and generally wraps the chain saw. When the saw chain is working, the cut wood chips generally do not splash onto the operator.

[0020] Specifically, the protective cover 2 includes a rod body 3, and the rod body 3 protrudes from the protective cover 2. Preferably, the position of the rod body 3 is the rotation point of the protective cover 2, so the rod body 3 is arranged at the end of the protective cover 2. A rotating part 4 is arranged on the rod body 3, and the rotating part 4 is the part connected to the main body 1. The rotating part 4 is a cylinder, which facilitates the coordinated connection of the rotating part 4.

[0021] The chain saw body 1 is provided with a connection hole 5, which is a protrusion structure, and the protrusion is provided on one side of the chain saw, so that the rotating part 4 can enter and rotate in the connection hole 5 of the chain saw body 1. At the same time, in order to better lock the rotating part 4 in the connection, a limit assembly is provided in the connection.

[0022] The limiting assembly includes a plurality of limiting plates 6, which are embedded in the slide grooves 7, that is, the limiting plates 6 can be slidably set in the slide grooves 7, and the limiting plates 6 interact with the rotating part 4 to achieve the adjustment and fixation of the position of the protective cover 2.

[0023] Furthermore, the limit plate 6 is connected to the slide groove 7 through a slider 13, wherein an electromagnet 8 is provided at the top of the slide groove 7, and the electromagnet 8 is electrically connected to the chain saw body 1. When the electric chain saw body 1 is started, the electromagnet 8 is energized and generates magnetic force to cause the slider 13 and the limit plate 6 to move along the slide groove 7. The moving direction of the limit plate 6 is to move away from the electromagnet 8. The slider 13 can be stuck in the slide groove 7 to achieve precise control of the position of the protective cover 2. On this basis, the slider 13 is connected to the slide groove 7 through the first spring 9, and when the electromagnet 8 is not energized, the limit plate 6 naturally stands in the slide groove 7.

[0024] It should also be noted that whether the electromagnet 8 is powered off or not, the height of the limit plate 6 in the slide groove 7 is different. In this regard, according to the above characteristics, two sets of inclined surfaces are arranged on the rotating part 4, wherein the first inclined surface 10 is arranged toward the inside of the connecting hole 5, and the second inclined surface 11 is arranged toward the outside of the connecting hole 5, wherein the cross-section of the first inclined surface 10 is larger, and regardless of when the electromagnet 8 is started or stopped, the first inclined surface 10 can contact the top angle of the limit plate 6, and the limit plate 6 can be pushed away to achieve a quick connection in the connecting hole 5. At the same time, the cross-section of the second inclined surface 11 is smaller than the first inclined surface 10. Only under the action of the first spring 9, the second inclined surface 11 contacts the top angle of the limit plate 6 and can withdraw from the connecting hole 5. When the electromagnet 8 is started, the second inclined surface 11 does not contact the top angle of the limit plate 6, and cannot withdraw, thereby ensuring safety.

[0025] The rotating part 4 is designed to be cylindrical, which not only improves the flexibility of rotation, but also is provided with a brush 12 at its end to effectively reduce the accumulation of sawdust during operation. When the rod body 3 withdraws from the connecting hole 5, impurities inside the connecting hole 5 can be cleaned to maintain cleanliness.

[0026] The protective cover 2 of the single-grip lithium-ion electric chain saw not only improves the convenience of connecting the protective cover 2 through the rotation design of the rod body 3 and the connecting hole 5, the control of the electromagnet 8 and the inclined setting of the rotating part 4, but also solves the instability of the quick connection during use and improves the safety of the quick connection.

[0027] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
