Embodiment two:
as shown in fig. 7, in comparative example one, another embodiment of the present invention is:
the surface of the sliding block 5 is sleeved with a corrugated pipe 35, and two ends of the corrugated pipe 35 are fixedly connected with the protecting shell 3 and the baffle 7 respectively; during operation, through installation bellows 35 for bellows 35 covers slider 5 and the part of spring 6 exposed outside, and when slider 5 and spring 6 are carrying out the slip shrink, bellows 35 plays the effect of protection slider 5 and spring 6, avoids dust etc. to fall into on slider 5 and the spring 6, thereby influences the shrink of spring 6.
Working principle: when the guardrail is touched to the protective case 3, the buffer cushion 8 and the baffle 7 can be impacted firstly, the baffle 7 carries the sliding block 5 and the spring 6 to slide in the storage groove 36, at the moment, the buffer cushion 8, the baffle 7 and the spring 6 provide buffering for the protective case 3, the protective case 3 is further protected, the protective case 3 is prevented from being damaged easily after being impacted for many times under the protection of no buffer device, and when the sliding block 5 slides in the storage groove 36, the sliding plate 9 and the protective plate 10 can be extruded, the anti-sliding plate 9 slides in the direction away from the protective case 3, the protective plate 10 shields the front of the blade 4, and then the blade 4 is protected when the buffer protection of the protective case 3 is realized. When the sliding block 5 presses the sliding plate 9, the first chamfer 12 on the sliding block 5 is in an inclined shape with the second chamfer 13 on the sliding plate 9, so that the sliding block 5 can better push the sliding plate 9 to move through the first chamfer 12, and the rolling ball 14 on the sliding plate 9 plays a guiding role on the sliding block 5. When the cushion pad 8 contacts the guardrail, the guide wheels 16 in the grooves 15 of the cushion pad 8 play a role in guiding and facilitating the rotation of the protective shell 3. After the blade 4 cuts green planting, the branches and leaves of green planting can be blocked between baffle 7 and protecting case 3 easily, promote slide bar 19 and rectangular plate 18 in the spout 17 this moment for rectangular plate 18 takes dead lever 20 and inserted bar 21 to remove, and dead lever 20 scrapes down the branches and leaves in the spout 17, and curved inserted bar 21 plays the effect between clean baffle 7 and the protecting case 3 simultaneously, and then reduces the existence branch and leaf between protecting case 3 and the baffle 7, thereby influences the normal slip of baffle 7, and baffle 7 when the slip shrink to protecting case 3 direction, can slide bar 19 to the rectangular plate 18 in, and then realize the removal of baffle 7. When the fixed rod 20 slides, the swing rod 23 and the impact ball 24 made of magnet materials are carried to slide together, when the impact ball 24 touches the first magnet 25, the fixed rod can be sprung out due to the principle of like poles repel, because the swing rod 23 is connected through a torsion spring, the swing rod 23 is reset after leaving the first magnet 25, at the moment, the impact ball 24 is close to the second magnet 26 and is used for the opposite attraction and separation of the impact ball 24 and the second magnet 26, so that the impact ball 24 and the second magnet 26 can attract each other to collide, vibration is generated, the inner wall of the chute 17 is assisted to be cleaned, and foreign matters adhered to the inner wall of the chute 17 are cleaned. When the sliding block 5 slides in the accommodating groove 36, the hollow elastic block 27 in the accommodating groove 36 is extruded, so that air in the elastic block 27 is blown out through the air duct 28, and then the rectangular plate 18 is blown, so that the rectangular plate 18 slides in the sliding groove 17 with the sliding rod 19, and further the rectangular plate 18 is not required to be manually pushed, the rectangular plate 18 can be slid, and the rectangular plate 18 can be cleaned. The pressing plate 29 and the baffle plate 30 are arc-shaped to better extrude the elastic block 27, when the elastic block 27 is extruded by the pressing plate 29 to generate deformation, the baffle plate 30 can compensate the gap between the elastic block 27 and the containing groove 36, so that the pressing plate 29 can better extrude the elastic block 27. When the air duct 28 sprays out air, the air duct 28 is affected by the inclined guide plate 31, so that the air is gathered between the air ducts 28, the pressure of the air is further enhanced, and meanwhile, the guide effect is formed, so that the air can conveniently push the rectangular plate 18. When gas passes through the guide plate 31, the connecting plate 32 is blown, so that the connecting plate 32 blows to the port of the gas guide pipe 28, and then the connecting plate 32 made of the magnet material and the rectangular plate 18 made of the magnet material repel each other, the rectangular plate 18 is assisted to slide, and as the two ends of the connecting plate 32 are made of rubber materials, deformation can be generated to slide, and gas can be blown out through the connecting plate 32.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the foregoing embodiments, and that the foregoing embodiments and description are merely illustrative of the principles of this invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, and these changes and modifications fall within the scope of the invention as hereinafter claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
