Before the actuating member 112 is inserted into the recess 111, the grass cutting mechanism 12 is at the first position, when the actuating member 112 is inserted into the recess 111, referring to fig. 7, the actuating member 112 interferes with the first clamping portion 1426 and the second clamping portion 1436, the first clamping portion 1426 rotates in the g direction with the first pin 1423 as the fixed point, and the second segment 1422 rotates in the b direction with the first pin 1423 as the fixed point; the second retaining portion 1436 rotates in the h direction with the fourth pin 1433 as a fixed point, the fourth segment 1432 rotates in the c direction with the fourth pin 1433 as a fixed point, and the deformation of the telescopic mechanism 14 is the same as the deformation of the telescopic mechanism 14 when the protection mechanism 13 meets an obstacle at the position a, which is not described herein. The deformation of the telescopic mechanism 14 drives the grass cutting mechanism 12 to move in the direction a. After the actuator 112 is fully inserted into the recess 111, the grass cutting mechanism 12 is retracted into the body 11, as shown in the retracted state of the grass cutting mechanism 12 in fig. 3 and 5. When the grass cutting mechanism 12 does not work, the grass cutting mechanism 12 is retracted into the machine body 11, so that the safety performance is ensured. When the actuating member 112 is pulled out of the recess 111, referring to fig. 8, the first retaining portion 1426 rotates in the i direction with the first pin 1423 as a fixed point, and the second segment 1422 rotates in the d direction with the first pin 1423 as a fixed point; the second retaining portion 1436 rotates in the j direction with the fourth pin 1433 as a fixed point, the fourth segment 1432 rotates in the e direction with the fourth pin 1433 as a fixed point, and the deformation of the telescopic mechanism 14 is the same as the deformation of the telescopic mechanism 14 after the protection mechanism 13 passes over the obstacle, which is not described herein. The deformation of the telescopic mechanism 14 drives the grass mowing mechanism 12 to move towards the direction f. After the actuator 112 is completely pulled out of the groove 111, the grass cutting mechanism 12 moves in the f direction to protrude the body 11, as shown in the working state of the grass cutting mechanism 12 in fig. 4 and 6.
