[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figure 1-Figure 5 The detachable lithium-electric grass trimmer includes a motor 2, a protective cover 1, a gripping rod 4 and a connecting portion 3. The protective cover 1 is designed to rotate around the outside of the motor 2, that is, the protective cover 1 is adjustable, and when matching different working angles, it can prevent the cut grass from splashing onto the operator.

[0021] A protruding connecting part 3 is provided on the motor 2, and a handle rod is provided on the connecting part 3. The handle rod can be rotatably connected to the connecting part 3. The rotation of the handle rod can be adapted to operators of different heights to perform operations. At the same time, a lithium battery pack 18 is provided at the end of the handle rod for powering the motor 2.

[0022] Furthermore, in order to facilitate the control of the position of the protective cover 1, a control rod 6 is slidably set through the connecting part 3, and a control plate 5 is configured on the protective cover 1. The control member is provided on both sides of the control rod 6, and the control plate 5 is connected to the outside of the protective cover 1. When the operator adjusts the control rod 6, that is, after the control rod 6 moves toward a control plate 5, the protective cover 1 follows the rotation to adapt to different mowing angles.

[0023] In order to facilitate the control of the control rod 6, a control block 7 is provided on the control rod 6, and the control block 7 has a first inclined surface 20 and a second inclined surface 21, and the first inclined surface 20 and the second inclined surface 21 are provided on both sides of the control block 7, and the directions of the first inclined surface 20 and the second inclined surface 21 are different. Furthermore, the two sides are respectively provided with a first inclined block 8 and a second inclined block 19, and the first inclined block 8 and the second inclined block 19 are respectively matched with the first inclined surface 20 and the second inclined surface 21, and at the same time ensure that when the first inclined block 8 moves downward, the control rod 6 rotates to one side with the cooperation of the first inclined surface 20, and conversely, when the second inclined block 19 moves upward, the control rod 6 rotates to the other side with the cooperation of the second inclined surface 21, thereby achieving the matching and regulating angle of the protective cover 1.

[0024] At the same time, the first inclined block 8 and the second inclined block 19 are connected by the moving block 9, and the moving block 9 slides in the holding rod. The movement of the moving block 9 will drive the control rod 6 to move synchronously. At the same time, a pressing block 10 is arranged in the middle of the holding rod, and the pressing block 10 is connected to the upper part of the holding rod 4 through the first spring 11. At the same time, the pressing block 10 is connected to the moving block 9, that is, the moving block 9 follows the pressing block 10 to match the movement.

[0025] The gripping rod 4 is designed with two handles, wherein the first handle 12 integrates a switch for controlling the start and stop of the motor 2, so that the operator can conveniently start or stop the motor 2 while holding the mower. The second handle 13 is movably connected to one side of the gripping rod 4, and includes a movable rod 14, which can slide in a movable groove 15, and the movable rod 14 is connected to the pressing block 10 in the gripping rod 4 through a thin rod 16.

[0026] When the operator is in use, by pulling or pushing the second handle 13, the movable rod 14 slides in the movable groove 15, thereby driving the thin rod 16 to move. That is, the thin rod 16 drives the pressing block 10 to move up or down, and overcomes the elastic force of the first spring 11 during the movement. After the position of the pressing block 10 changes, it eventually affects the moving block 9 and the control rod 6 through the linkage structure, thereby adjusting the angle of the protective cover 1.

[0027] Furthermore, limit members are provided on both sides of the movable rod 14, and the limit members cannot break through the movable groove 15. Therefore, there are certain limits in pulling and pushing the movable rod 14. At the same time, during the pushing activity during use, the lawn mower can be biased to the right of the operator. At this time, the control rod 6 also moves to the right, and the protective cover 1 can adapt and rotate in real time, and so does the reverse, so as to achieve better protection for the user.

[0028] 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.
