The gear ring 13 is installed on the outside of the rotating shaft 4, and the gear ring 13 is located inside any rotating seat 3. The force-applying screw 14 is installed through the top center of the rotating seat 3. The bottom of the force-applying screw 14 is connected to the arc-shaped block 16, and the arc-shaped block 16 is located inside the rotating seat 3. The limiting slide rod 15 is symmetrically installed on the top of the arc-shaped block 16, and the limiting slide rod 15 passes through the top of the rotating seat 3. The locking tooth 17 is installed on the bottom of the arc-shaped block 16, and the locking tooth 17 matches the gear ring 13. The top of the force-applying screw 14 is equipped with a handle 18, and the outside of the handle 18 is provided with anti-slip texture 19. The rotating base 3 provides an installation position and space for the locking assembly; the rotating shaft 4 provides an installation position for the gear ring 13; the rotating base 3 provides an installation position for the force-applying screw 14 and a through hole for the limiting slide rod 15; the force-applying screw 14 provides an installation position for the arc-shaped block 16 and the handle 18; the handle 18 provides an installation position for the anti-slip texture 19, which increases the friction between the handle 18 and the hand, making it easier for the operator to apply force; the arc-shaped block 16 provides an installation position for the limiting slide rod 15 and the locking tooth 17; the limiting slide rod 15 restricts the movement trajectory of the arc-shaped block 16; the locking tooth 17 matches the gear of the gear ring 13, thus locking the gear ring 13 and fixing the rotating shaft 4; when it is necessary to adjust the obstruction of the protective baffle... When adjusting the angle, manually rotate the baffle body 7, causing the baffle body 7 to drive the connecting seat 5 and the rotating shaft 4 to rotate. The rotation of the rotating shaft 4 inside the rotating seat 3 drives the gear ring 13 to rotate together. After rotating the baffle body 7 to the required angle, rotate the handle 18 to drive the force screw 14 to rotate. The rotating force screw 14 causes the arc block 16 to move downward under the limiting guide action of the limiting slide rod 15 until the locking teeth 17 at the bottom of the arc block 16 engage with the gear of the gear ring 13, thereby fixing the rotating shaft 4 and preventing the protective baffle from rotating after the angle adjustment. By rotating the force screw 14, the arc block 16 is adjusted to make the locking teeth 17 engage or disengage with the gear ring 13, thereby switching between the fixed and rotatable states of the rotating shaft 4, which facilitates the adjustment of the protective baffle angle.

[0029] Working principle: Before using the mini-tiller baffle, check whether there are any problems that may affect its use. First, install the mini-tiller baffle onto the mini-tiller, aligning the mounting threaded hole 2 on the mounting bracket 1 with the mounting hole on the mini-tiller. Pass the screw through the mounting threaded hole 2 and the mounting hole on the mini-tiller in sequence, and then tighten the mounting bracket 1 and the mini-tiller by turning the nut. When it is necessary to adjust the blocking angle of the protective baffle, manually rotate the baffle body 7, which will drive the connecting seat 5 and the rotating shaft 4 to rotate. The rotation of the rotating shaft 4 inside the rotating seat 3 will drive the gear ring 13 to rotate together. After rotating the baffle body 7 to the required angle, turn the throttle 18 to drive the force-applying screw 14 to rotate. The rotating force-applying screw 14 will cause the arc block 16 to move downward under the limiting guide of the limiting slide rod 15 until the locking teeth 17 at the bottom of the arc block 16 lock the gear of the gear ring 13, thereby fixing the rotating shaft 4 and preventing the protective baffle from rotating after the angle is adjusted.

[0030] When the baffle body 7 needs to be replaced, rotate the locking nut 12 to separate it from the locking screw 11, and then rotate the locking screw 11 outward to remove it from the inside of the fixing strip 6. At this time, the T-shaped slide bar 9 on the top of the baffle body 7 can slide outward along the T-shaped slide groove 8 to separate the baffle body 7 from the fixing strip 6. During installation, align the T-shaped slide bar 9 on the top of the baffle body 7 with the T-shaped slide groove 8 and slide it inward until the T-shaped slide bar 9 slides to the innermost side of the T-shaped slide groove 8. Rotate the locking screw 11 to make it pass through the inner front wall of the T-shaped slide groove 8, the through hole 10 and the back of the fixing strip 6 in sequence. Then, the baffle body 7 is fixed by the cooperation of the locking nut 12 and the locking screw 11.
