[0027] Example:
[0028] As attached Figure 1 To Attachment Figure 5 As shown:
[0029] The utility model provides a weeder safety protection device, comprising a mounting base 1 and a weeder body 2, a first slide groove 3 is provided at the top of the mounting base 1, a pair of first sliding blocks 4 are slidably installed on both sides of the first slide groove 3, a pair of arc-shaped clamping plates 5 are symmetrically installed on the top of the pair of first sliding blocks 4, a connecting groove 6 is provided at the bottom end of the mounting base 1, a protective plate 7 is installed at the bottom end of the mounting base 1, a connecting block 8 is installed at the top of the protective plate 7, a limiting groove 9 is penetrated on one side of the connecting block 8, a second slide groove 10 is provided on one side of the mounting base 1, and the second slide groove 10 is communicated with the connecting groove 6, and a limiting block 11 is slidably installed in the second slide groove 10.
[0030] Among them, a pair of arc-shaped clamping plates 5 are installed with anti-skid pads 12 on opposite sides, and the sizes of the pair of arc-shaped clamping plates 5 match the sizes of the mounting rods of the lawnmower body 2. The anti-skid pads 12 can increase the friction between the pair of arc-shaped clamping plates 5 and the lawnmower body 2, thereby improving the stability of the arc-shaped clamping plates 5 installed on the lawnmower body 2.
[0031] The size of the connection groove 6 matches that of the connection block 8 , so that the connection block 8 can enter the connection groove 6 , thereby enabling the protection plate 7 to be quickly installed on the bottom end of the mounting seat 1 .
[0032] Among them, the size of the limit block 11 matches the size of the limit groove 9, so that the limit block 11 can enter the limit groove 9. When installing the protective plate 7, the staff first pulls the limit block 11 through the pull block 16 to make the limit block 11 slide in the second slide groove 10 and no longer block the connecting groove 6. Then, the connecting block 8 at the top of the protective plate 7 is inserted into the connecting groove 6 and the pull block 16 is released. Under the action of the rebound of the compression spring 13, the limit block 11 enters and passes through the limit groove 9, thereby fixing the protective plate 7 to the bottom end of the mounting seat 1.
[0033] Among them, compression springs 13 are installed on both sides of the limit block 11, and the other end of the compression spring 13 is connected to one side of the second slide groove 10. Through the rebound of the compression spring 13, the limit block 11 can enter the limit groove 9 to fix the protective plate 7.
[0034] Among them, a bidirectional screw 14 is rotatably installed in the first slide groove 3, and the bidirectional screw 14 passes through the front and rear sides of a pair of first sliders 4 and is threadedly connected with the pair of first sliders 4. Through the rotation of the bidirectional screw 14, under the limiting action of the first slide groove 3, the pair of first sliders 4 move toward or away from each other at the same time, so that the mounting seat 1 can be fixed on the lawnmower body 2 or the mounting seat 1 can be removed from the lawnmower body 2.
[0035] A knob 15 is installed on one side of the mounting base 1 , and the knob 15 is connected to the bidirectional screw 14 . By rotating the knob 15 , the bidirectional screw 14 is driven to rotate, thereby driving a pair of first sliders 4 to move toward or away from each other at the same time.
[0036] A pulling block 16 is installed on one side of the limiting block 11 to facilitate pulling the limiting block 11 .
[0037] The working principle of this embodiment is as follows: when using the lawn mower safety protection device, the staff first places the safety protection device just below the lawn mower body 2 so that the mounting rod of the lawn mower body 2 is located between the pair of arc-shaped clamping plates 5, and then rotates the knob 15, which drives the bidirectional screw 14 to rotate. Under the limiting action of the first slide groove 3, the pair of first sliders 4 move toward each other at the same time, thereby driving the pair of arc-shaped clamping plates 5 to move, so that the pair of arc-shaped clamping plates 5 can clamp the mounting rod of the lawn mower body 2 in the middle, and increase the friction between the pair of arc-shaped clamping plates 5 and the mounting rod of the lawn mower body 2 through the anti-skid pad 12, thereby improving the stability of the safety protection device when in use. During the weeding process, debris brought up by the rotating blade will adhere to or hit the protective plate 7, preventing the debris from directly adhering to or hitting the staff and causing harm to the staff. After the weeding work is completed, the staff can rotate the knob 15 in the opposite direction so that the pair of After the arc clamping plates 5 are moved back to back at the same time, the safety protection device can be removed, which is convenient for carrying the lawn mower body 2 and the safety protection device separately, reducing space occupancy and improving convenience. In addition, if a lot of dirt and other debris adhere to the protective plate 7, the staff can pull the pull block 16, and the pull block 16 drives the limit block 11 to move, so that the limit block 11 is disengaged from the limit groove 9 and no longer limits the protective plate 7. At this time, the protective plate 7 can be taken out and cleaned and maintained by pulling the protective plate 7 downward. After the cleaning and maintenance are completed, the staff aligns the connecting block 8 with the connecting groove 6, and drives the limit block 11 to move by pulling the pull block 16. At this time, the limit block 11 no longer blocks the connecting groove 6, and moves the protective plate 7 upward to make the connecting block 8 enter the connecting groove 6, and then the staff releases the pull block 16, and under the action of the compression spring 13 rebounds, the limit block 11 enters and passes through the limit groove 9 to fix the protective plate 7.
