[0033] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0034] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0035] like Figures 1 to 4 As shown, the protective component for a lawnmower provided in this embodiment of the present invention includes:

[0036] Handle 1;

[0037] Connecting rod 2: The right end face of connecting rod 2 is fixedly connected to the left end face of handle 1;

[0038] Cutting mechanism 3: Cutting mechanism 3 is fixedly connected to the left end face of connecting rod 2;

[0039] Protective mechanism 4: Protective mechanism 4 is located inside the cutting mechanism 3, and includes:

[0040] Fixed shell 410: The outer surface of the fixed shell 410 is fixedly connected to the outer surface of the cutting mechanism 3;

[0041] Protective shell 420: Two protective shells 420 are provided, and the outer surfaces of both protective shells 420 are slidably connected to the inner wall of the fixed shell 410;

[0042] Pulling component 430: The lower end face of the pulling component 430 is fixedly connected to the upper surface of the right protective shell 420;

[0043] Springback assembly 440: Springback assembly 440 is disposed inside the fixed housing 410.

[0044] refer to Figure 2 As shown, there are two spring-loaded components 440, and the two spring-loaded components 440 include:

[0045] Telescopic rod 441: One end of the telescopic rod 441 near the protective shell 420 is fixedly connected to the outer surface of the protective shell 420, and the telescopic rod 441 is arc-shaped;

[0046] Telescopic spring 442: The telescopic spring 442 is sleeved on the outer surface of the telescopic rod 441. One end of the telescopic spring 442 near the protective shell 420 is fixedly connected to the outer surface of the protective shell 420. The telescopic spring 442 is arc-shaped.

[0047] Using the above solution: by pulling the puller 430 in a circular trajectory, the two protective shells 420 slide along the inner wall of the fixed shell 410 until the protective shells 420 fit together. When the protective shells 420 move, the rebound component 440 can be pulled, which will cause the telescopic rod 441 to extend and the telescopic spring 442 to generate tension. When it is not necessary to protect the cutting mechanism 3, the telescopic spring 442 releases the tension and pulls the protective shells 420 back to the initial position.

[0048] refer to Figure 2 As shown, a support plate 5 is provided inside the fixed shell 410. The outer surface of the support plate 5 is fixedly connected to the inner wall of the fixed shell 410. The left and right sides of the support plate 5 are fixedly connected to one end of the telescopic rod 441 and the telescopic spring 442.

[0049] Using the above scheme: the support plate 5 mainly serves to support the rebound assembly 440.

[0050] refer to Figure 3 As shown, a locking assembly 6 is provided inside the protective housing 420. The locking assembly 6 includes:

[0051] Clamping groove 601: Clamping groove 601 is provided on the opposite side of the protective shell 420;

[0052] Clamping block 602: There are two clamping blocks 602. The outer surfaces of the two clamping blocks 602 are slidably connected to the inner wall of the clamping groove 601. The left end face of the clamping block 602 is in contact with the inner wall of the right protective shell 420.

[0053] Using the above scheme: when the two protective shells 420 move, the clamping block 602 will be squeezed by the right clamping groove 601, causing the clamping block 602 to move along the inner wall of the left clamping groove 601 to the opposite side until the distance between the clamping blocks 602 is less than the length of the clamping groove 601, so that the clamping block 602 can pass through the right clamping groove 601 and fit tightly against the inner wall of the right protective shell 420.

[0054] refer to Figure 4 As shown, a telescopic component 7 is provided on the opposite side of the clamping block 602. There are two telescopic components 7, each including:

[0055] Telescopic column 701: One end of the telescopic column 701 is fixedly connected to the opposite side of the clamping block 602, and the opposite end of the telescopic column 701 is fixedly connected to the inner wall of the left protective shell 420;

[0056] Pressure relief spring 702: Pressure relief spring 702 is sleeved on the outer surface of telescopic column 701. One end of pressure relief spring 702 is fixedly connected to the opposite side of clamping block 602, and the opposite end of pressure relief spring 702 is fixedly connected to the inner wall of left protective shell 420.

[0057] Using the above scheme: when the clamping block 602 moves to the opposite side, the clamping block 602 can pull the telescopic column 701 and the pressure relief spring 702, causing the telescopic column 701 to extend and the pressure relief spring 702 to generate tension. When the clamping block 602 enters the right clamping groove 601, the pressure relief spring 702 releases the tension, pulling the clamping block 602 back.

[0058] refer to Figure 4 As shown, the upper surface of the clamping block 602 is provided with a pressing element 8. There are two pressing elements 8, and the lower end faces of the two pressing elements 8 are fixedly connected to the upper surface of the clamping block 602.

[0059] Using the above solution: when it is not necessary to protect the cutting mechanism 3, simply press the pressing member 8 on the opposite side. The pressing member 8 can drive the clamping block 602 to move to the opposite side until the distance between the clamping blocks 602 is less than the length of the clamping groove 601, so that the clamping block 602 can be disengaged from the right clamping groove 601.

[0060] refer to Figure 3 As shown, a travel groove 9 is provided on the upper surface of the left protective shell 420, and the inner wall of the travel groove 9 is slidably connected to the outer surface of the pressing part 8.

[0061] Using the above scheme: the stroke groove 9 mainly serves to provide a moving path for the pressing part 8.

[0062] The working principle of this utility model:

[0063] When in use, when the cutting mechanism 3 is not in use, by pulling the pulling member 430 and the pressing member 8 in a circular trajectory, the two protective shells 420 slide along the inner wall of the fixed shell 410. At the same time, the clamping block 602 will be squeezed by the right clamping groove 601, causing the clamping block 602 to move to the opposite side along the inner wall of the left clamping groove 601 until the distance between the clamping blocks 602 is less than the length of the clamping groove 601. Then the clamping block 602 can pass through the right clamping groove 601 and fit tightly against the inner wall of the right protective shell 420. At this time, the protective shells 420 also fit together. When the protective shells 420 move, the rebound component 440 can be pulled, causing the telescopic rod 441 to extend and the telescopic spring 442 to generate tension. At this time, the cutting disc on the cutting mechanism 3 is protected.

[0064] When the cutting mechanism 3 is needed, simply press the pressing member 8 to the opposite side. The pressing member 8 can drive the clamping block 602 to move to the opposite side until the distance between the clamping blocks 602 is less than the length of the clamping groove 601. Then the telescopic spring 442 and the pressure relief spring 702 will release their tension, pulling the protective shell 420 and the clamping block 602 back to their initial positions, exposing the cutting disc for easy operation.

[0065] In summary, this protective component for lawnmowers, through its handle 1, connecting rod 2, cutting mechanism 3, protective mechanism 4, support plate 5, clamping component 6, telescopic component 7, pressing component 8, and stroke groove 9, solves the problem that if passersby do not notice a fallen lawnmower, their legs may be scratched due to friction from the exposed blades when passing by, greatly affecting their safety.
