3) when a worker works vertically, the clamping block 5-1-2 is positioned in the clamping groove 5-2-3, and the sliding plate 5-2-4 is supported on the pedal 6);
4) when a worker squats down to work, the expansion plate 5-2 and the movable plate 5-3 are pushed to the middle position of the semicircular ring I3-1, and then squat down and sit on the rotating plate I5-3-2.
When the protective tool is used, the protective tool is convenient to wear, has more protective effects compared with the protective functions of the existing protective tools, and can better protect the safety of workers.
The working principle of the invention is as follows: when the safety vest is worn, the protection device III 3 and the protection device IV 4 are unfolded into a circular ring, then workers enter the protection device III 3 and the protection device IV 4 from the lower ends of the protection device III 3 and the protection device IV 4 and wear the safety vest 2-1, finally the screw rods 1-8 are rotated, the screw rods 1-8 move up and down in the threaded cylinders 1-9, the inner shell 1-4 is made to adapt to the height of a user, and the rotation of the screw rods 1-8 is stopped after the inner shell 1-4 covers the head of the user, so that the wearing is completed;
the protection device I1 is internally provided with a plurality of springs 1-14, when an external force impacts the outer shell 1-1 on the protection device I1, the outer shell 1-1 drives the sliding barrel 1-2 to move downwards, the sliding barrel 1-2 drives the circular plate I1-13 to move downwards, and the circular plate I1-13 compresses the springs 1-14, so that the springs 1-14 counteract a part of impact force, further the impact of the external force on the inner shell 1-4 is reduced, and the purpose of protecting the head of a worker is achieved; the inner shell 1-4 and the safety helmet are structurally different in that a plurality of through holes are formed in the top end of the inner shell 1-4, the motor 1-11 is started, the motor 1-11 drives the fan blades to rotate, air can be blown to the head of a worker through the through holes in the upper end of the inner shell 1-4, the worker can work more quickly in summer, and the probability of heatstroke of the worker is reduced; the height of the screw rods 1-8 needs to be adjusted when the protective device I1 moves vertically, the heads of workers are always protected by the inner shells 1-4 under the condition that the heights of the screw rods 1-8 are not adjusted, and the lower baffle plates are connected to the screw rods 1-8 through bearings, so that when the rectangular rods 1-10 drive the telescopic rods 1-5 to rotate, the telescopic rods 1-5 drive the inner shells 1-4 to rotate, and the probability that the inner shells 1-4 are separated from the heads of the workers when the workers turn heads is reduced;
the safety vest 2-1 is worn on a worker, so that the carrying performance of the safety vest can be ensured, the device is prevented from being separated from the worker in the working process of the worker, and the protection effect of the safety vest is weakened;
after the scaffold is worn, the semicircular ring I3-1 and the semicircular ring II 4-1 form a circular ring shape and reach the state shown in a figure 8, and after the scaffold is worn, when a worker is subjected to external force in the working process or leans forward or leans backward due to unstable gravity center of the worker, the semicircular ring I3-1 and the semicircular ring II 4-1 after being combined are larger than the distance between the two vertical rods 7 of the scaffold, so that the semicircular ring I3-1 and the semicircular ring II 4-1 can ensure that the worker cannot fall out of the scaffold from a gap between the two vertical rods 7, and the probability of falling injury of the worker is further reduced; meanwhile, the semicircular ring I3-1 and the semicircular ring II 4-1 occupy too large space after being combined, so that a worker is difficult to stagger the body position on the pedal 6, the semicircular ring I3-1 and the semicircular ring II 4-1 can slide along the connecting rod II 4-3 and the connecting rod I3-1 to achieve the state shown in the figure 6, when the semicircular ring I3-1 and the semicircular ring II 4-1 achieve the state shown in the figure 6, the occupied space is reduced, the worker can conveniently walk through the semicircular ring I3-1 and the semicircular ring II 4-1, and meanwhile, the maximum length between the semicircular ring I3-1 and the semicircular ring II 4-1 is increased relative to the diameters of the semicircular ring I3-1 and the semicircular ring II 4-1, so that the function of preventing the worker from falling out of the scaffold cannot be influenced;
the invention is also provided with a supporting device 5, a semicircular ring II 4-1 is positioned in front of a worker, a semicircular ring I3-1 is positioned behind the worker, the supporting device 5 is arranged at the lower end of the semicircular ring I3-1, when the worker works vertically, a clamping block 5-1-2 is matched with a clamping groove 5-2-3, so that the supporting device 5 achieves the state shown in figure 14, a universal wheel 5-2-5 is supported at the upper end of a pedal 6, the upper end of a sliding plate 5-2-4 is supported on the clamping block 5-1-2, the clamping block 5-1-2 drives a connecting plate 5-1-1 to support the semicircular ring I3-1, as the semicircular ring I3-1 is connected with a protective device IV 4, and the protective device II 2 and the protective device I1 are arranged at the upper end of the semicircular ring I3-1, therefore, the protection device I1, the protection device II 2, the protection device III 3 and the protection device IV 4 are supported by the supporting force of the supporting device 5, the gravity of the protection device I1, the protection device II 2, the protection device III 3 and the protection device IV 4 required by workers is reduced, and the fatigue of the workers is further reduced; when a worker squats to work, the expansion plates 5-2 and the movable plates 5-3 on the two sides are pushed until the two expansion plates 5-2 are adjacent, then the worker squats downwards, the fixed plate 5-2-1 is separated from the connecting plate 5-1-1, so the clamping block 5-1-2 is separated from the clamping groove 5-2-3, when the worker squats downwards, the sliding plate 5-2-4 moves towards the sliding groove 5-2-2, the rotating plate I5-3-2 and the rotating plate II 5-3-3 rotate around the hinge to the state shown in figure 15, at the moment, the lower ends of the universal wheel 5-2-5 and the rotating plate II 5-3 are supported on the ground, the length of the connecting plate 5-1-1 is equal to that of the fixed plate 5-2-1, workers can sit on the inclined plane of the rotating plate I5-3-2, and leg paralysis caused by long-time squat is avoided.
