The bottom end of the second hydraulic piston rod 502 is connected to the interior of the stable nail grasping mechanism 3 through an oil channel 504.
[0022] When the trigger assembly 2 is driven to move upward in a certain direction, the first hydraulic piston rod 402 is pushed, thereby pushing the hydraulic oil in the inner cavity of the first hydraulic cylinder 401 to be introduced into the interior of the second hydraulic cylinder 501 through the connecting pipe 403, so as to first push the stable nail grasping mechanism 3 in a certain direction to move downward as a whole and extend, and then the hydraulic oil in the inner cavity of the second hydraulic cylinder 501 will push the oil valve disc 503 to flip open, and finally the hydraulic oil is introduced into the bottom part of the stable nail grasping mechanism 3 through the oil channel 504, pushing the bottom of the stable nail grasping mechanism 3 to be pushed out.
[0023] like Figure 2 As shown, the trigger assembly 2 includes a movable column 201, a rotating ball 202 and a first spring 203; The movable column 201 is fixedly installed on one side of the bottom of the lawn mower body 1 , and the rotating ball 202 is movably sleeved on the bottom end of the movable column 201 . The top end of the rotating ball 202 is elastically connected to the bottom of the lawn mower body 1 through the first spring 203 .
[0024] The above solution is adopted: by providing a rotating ball 202, the design of the rotating ball 202 can keep the lawn mower body 1 moving smoothly as a whole, and when encountering moss, slopes or gravel, the rotating ball 202 and the movable column 201 will move upward smoothly, and compress the first spring 203, so that the top end of the first hydraulic piston rod 402 is pushed, and the first spring 203 can assist the movable column 201 and the rotating ball 202 to subsequently reset downward.
[0025] like Figure 3 、 Figure 4 、 Figure 6 and Figure 9 As shown, the stable nail grabbing mechanism 3 includes a movable frame 301, a movable plate 302 and a nail grabbing assembly 303; The movable frame 301 is movably mounted on both sides of the outer end of the surface of the lawn mower body 1, the movable plate 302 is arranged in the middle of the surface of the lawn mower body 1, and the nail grabbing assembly 303 is arranged at the bottom ends of the movable frame 301 and the movable plate 302; The nail grabbing assembly 303 includes a fixed block 3031, a hydraulic chamber 3032, a movable rod 3033 and a nail grabbing block 3034; The fixed block 3031 is arranged at the bottom of the movable frame 301 and the movable plate 302, the hydraulic chamber 3032 is opened at the bottom of the inner cavity of the fixed block 3031, the movable rod 3033 is movably installed inside the hydraulic chamber 3032, the nail grabbing block 3034 is arranged at the bottom of the movable rod 3033, and the top of the hydraulic chamber 3032 is connected to the oil channel 504.
[0026] Adopting the above scheme: when the hydraulic oil in the inner cavity of the second hydraulic cylinder 501 is squeezed to push the oil valve flap 503 to flip open, the hydraulic oil will be introduced into the top of the inner cavity of the hydraulic cavity 3032 through the oil channel 504, which can smoothly push the movable rod 3033 and the nail grabbing block 3034 to move downward as a whole.
[0027] like Figure 6 and Figure 9 As shown, the bottom end of the nail grabbing block 3034 is provided with a plurality of sharp cones, and the plurality of sharp cones are made of metal.
[0028] The above solution adopts the pointed cone design at the bottom of the grabbing block 3034 so that when the grabbing block 3034 is extended, the bottom of the grabbing block 3034 will be inserted into the ground, thereby preventing the lawn mower body 1 from rolling over and stabilizing the entire movement.
[0029] like Figure 8 As shown, the lawn mower body 1 is provided with a shock absorbing mechanism 6 located inside the movable frame 301 and the movable plate 302. The shock absorbing mechanism 6 includes a first limit block 601, a first shock absorbing assembly 602 and a second shock absorbing assembly 603. The first limit block 601 is fixedly mounted on the inner end of the movable frame 301 and is located on the inner wall of the lawn mower body 1. The first shock absorbing assembly 602 is disposed at the bottom of the first limit block 601. The second shock absorbing assembly 603 is fixedly mounted on the inner end of the movable plate 302 and is located inside the lawn mower body 1. The first shock absorbing assembly 602 includes a first limiting rod 6021, a moving block 6022, a second spring 6023 and a linkage arm 6024; The first limiting rod 6021 is fixedly installed inside the lawn mower body 1, and the first limiting rod 6021 is located below the movable frame 301. The moving block 6022 is movably installed on the surface of the first limiting rod 6021. The inner end of the moving block 6022 is elastically connected to the inner wall of the lawn mower body 1 through the second spring 6023. The linkage arm 6024 is hinged between the moving block 6022 and the inner end of the movable frame 301.
[0030] With the above solution, when the movable frame 301 moves downward as a whole, the linkage arm 6024 will be squeezed and deflected, thereby pushing the moving block 6022 to move toward each other, causing the second spring 6023 to be compressed, and the elastic force of the second spring 6023 will buffer and reduce shock for a series of activities.
[0031] like Figure 8 As shown, the second shock absorbing assembly 603 includes a second limiting rod 6031, a second limiting block 6032 and a third spring 6033; The second limiting rod 6031 is set in the middle of the surface of the lawn mower body 1, the second limiting block 6032 is slidably connected to the surface of the second limiting rod 6031, and the bottom end of the second limiting block 6032 is elastically connected to the inner wall of the lawn mower body 1 through the third spring 6033.
[0032] With the above solution, when the movable plate 302 and the second limit block 6032 are driven to move downward as a whole, the third spring 6033 will be compressed, and the elastic force of the third spring 6033 can buffer and reduce the overall movement of the movable plate 302 and the second limit block 6032.
[0033] like Figure 8 As shown, the inner wall of the third spring 6033 is slidably connected to the surface of the second limiting rod 6031.
[0034] With the above solution, when the second limiting block 6032 moves up and down as a whole, it moves vertically along the surface of the second limiting rod 6031 . At the same time, the second limiting rod 6031 can synchronously limit the third spring 6033 when it is expanding and contracting.
[0035] like Figure 10 As shown, the surface of the lawn mower body 1 is provided with a protection assembly 7 located outside the bottom end of the nail grabbing assembly 303. The protection assembly 7 includes a protection box 701, a support seat 702, a shielding plate 703 and a fourth spring 704; The protection box 701 is arranged on the surface of the lawn mower body 1, and the protection box 701 is located on the outside of the bottom end of the nail grabbing assembly 303, the support seat 702 is arranged in the middle of the outside of the bottom end of the protection box 701, and the baffle plate 703 is movably installed at the bottom of the protection box 701, and the outer end part of the baffle plate 703 is movably connected to the inner wall of the support seat 702, and the middle part of the inner end of the baffle plate 703 is elastically connected to the inner wall of the support seat 702 through the fourth spring 704.
[0036] The above solution is adopted: through the design of the protective box 701 and the shielding plate 703, the bottom end of the nail grabbing assembly 303 can be shielded and protected, and then when the nail grabbing assembly 303 moves downward as a whole, the shielding plate 703 will be squeezed and pushed open.
[0037] The working principle and use process of the present invention: First, by starting the lawn mower body 1 to move and mow the grass, when encountering a slope, moss and gravel in a certain direction, the rotating ball 202 and the movable column 201 on one side will be squeezed and pushed upward as a whole, and then the top of the first hydraulic piston rod 402 will be supported by the inner wall of the lawn mower body 1, so that the hydraulic oil at the bottom of the inner cavity of the first hydraulic cylinder 401 is pushed through the connecting pipe 403 and introduced into the inner cavity of the second hydraulic cylinder 501, which will first push the second hydraulic piston rod 502 and the fixed block 3031 downward as a whole, so that the fixed block 3031 in a certain direction pushes the baffle 703 downward to support the seat 702 at the axis center and flip open, so that the hydraulic cavity 3032 is smoothly extended.
[0038] Then, when the hydraulic chamber 3032 is moved and fixed, the hydraulic oil introduced into the second hydraulic cylinder 501 will push the oil valve flap 503 to flip open, and then be introduced into the top of the inner cavity of the hydraulic chamber 3032 through the oil channel 504, so as to push the movable rod 3033 and the grabbing block 3034 to move downward as a whole, so that the bottom end part of the grabbing block 3034 can be smoothly extended and inserted into the bottom surface, so that the lawn mower body 1 can be stabilized as a whole, thereby preventing the lawn mower body 1 from tilting and tipping over due to moss, gravel or slope.
[0039] At the same time, if the fixed block 3031 in the front-to-back direction moves downward as a whole, it will push the first limit block 601 to move downward as a whole, and the downward movement of the first limit block 601 will cause the second spring 6023 to be squeezed and deflected, so as to push the movable block 6022 to slide along the surface of the first limit rod 6021, thereby compressing the second spring 6023. If the fixed block 3031 in the left-to-right direction moves downward as a whole, the second limit block 6032 will slide downward along the surface of the second limit rod 6031 as a whole, thereby compressing the third spring 6033. Finally, the buffering of the second spring 6023 and the third spring 6033 can assist in buffering and shock-absorbing the overall up and down movement of the nail grabbing assembly 303.
