Content of the Utility Model

For example, the working mode of the motor can be switched among ECO, REG, and MAX, and it is also displayed in real time on the display screen. In this way, the motor can be switched from the original single working mode to multiple working modes, so as to adapt to different working conditions and meet the diverse usage requirements.

[0025] Please refer to Figures 1 to 3 , the chainsaw with a gear shifting structure in the figure mainly designs components such as a transparent cover 1, a display screen 2, a rotating part 3, a linkage gear 4, a fixing part 5, an electrical control component 6, and a fuselage 7. The core innovation of this case is to use the rotating part 3 to drive the linkage gear 4, and the linkage gear 4 further converts the electrical signal to the electrical control component 6, and the electrical control component 6 thus sends an instruction to the motor to work according to the set mode, so as to meet the usage requirements of different working conditions.

[0026] The transparent cover 1 in the figure is mainly used to observe the display content of the display screen 2 while fixing the rotating part 3. The overall shape of the transparent cover 1 is a round cap shape, which has a top cover 11. Below the top cover 11 are two arc-shaped and spaced buckles 12 and positioning plates 13 respectively. The above-mentioned buckle 12 cooperates with the convex 51 with the same arc-shaped structure on the fixing part 5 to achieve fixed buckling, that is, the convex 51 extends outwards to limit the pulling out of the transparent cover 1, and the positioning plate 13 is inserted and assembled with the arc-shaped positioning hole 52 on the fixing part 5, so as to provide positioning for the installation and fixation of the transparent cover 1.

[0027] The display screen 2 in the figure is an existing component, and three working modes, namely ECO, REG, and MAX, can be displayed on its screen. At the same time, the remaining power can also be displayed. The back of the display screen 2 is a corresponding data plug 21 structure. The display screen 2 is located inside the transparent cover 1 and fixed on the first step 53 of the fixing part 5.

[0028] The rotating part 3 in the figure mainly drives the linkage gear 4 to rotate. The column body of the rotating part 3 is a round cap-shaped structure with a hollow interior and openings at both ends. The rotating part 3 is designed with a second step 31 in the direction towards the transparent cover 1. The diameter of the second step 31 corresponds to the diameter of the top cover 11 of the transparent cover 1, so that the top cover 11 of the transparent cover 1 is matched at this position. At the edge position in the opposite direction, the rotating part 3 is designed with a ring groove 32 structure with a certain arc length, and the fixing part 5 is designed with a limiting convex 54 structure protruding outwards at the corresponding position, so that it is convenient for the limiting convex 54 to perform limiting movement in the ring groove 32 to realize the rotational buckling of the rotating part 3 and the fixing part 5, so as to limit the rotation angle of the rotating part 3 and avoid over-rotation. As shown in the figure, the above-mentioned limiting convex 54 and ring groove 32 are both used in two and are symmetrically arranged, so as to provide a good rotation effect. In order to facilitate the rotation of the rotating part 3, a ball seat 55 structure can be designed on one of the limiting convexes 54, and a ball is placed in the ball seat 55. The ball is closely attached to the inner wall of the rotating part 3, so as to achieve a good rolling effect and facilitate the rotation of the rotating part 3. The rotating part 3 is designed with teeth with a certain arc length on the inner wall, and the teeth form a rotational meshing with the linkage gear 4, that is, when the rotating part 3 rotates, the linkage gear 4 can be driven to rotate. The fixing part 5 in the figure is fixed on the fuselage 7 by screws.

[0029] The linkage tooth 4 has a design with a driving rod 41 in addition to the structure of a conventional tooth. In order to place the linkage tooth 4, the fixing member 5 is designed with a tooth groove 56 structure at the corresponding position. The interior of the tooth groove 56 is integrally penetrated, which facilitates the driving rod 41 to act with the electric hole member to fix the linkage tooth 4 on the fixing member 5 and cooperate with the electric control member 6. The above-mentioned electric control member 6 is electrically signal-matched with the circuit board of the chainsaw, so that the generated electric signal can be transmitted to the motor, enabling the motor to operate according to the set mode and be displayed on the display screen 2. The specific circuit arrangement of the electric control member 6 can refer to the prior art, as long as it can convert the rotation data of the linkage tooth 4 into an electric signal.
