The working principle is as follows:

when using, wear cap body 1 on user's head through cap area 2, when meeting building site high altitude weight thing, when the weight thing strikes to the cap body 1 on the time pass cap body 1 top wall face and fall to cap body 1 inside slow piece 4 on, make the whereabouts point direction of weight thing take place the skew through the inside slow groove 6 of slow piece 4, when the weight thing whereabouts point direction takes place the skew simultaneously, make the left and right sides both ends of slow piece 4 carry out the adaptation formula slope through the whereabouts inertia of weight thing and adjust, thereby change the whereabouts point direction and the puncture direction of weight thing, thereby avoid the direct puncture cap body 1 of weight thing to carry out the condition emergence of fatal puncture to the human head.

When the top of the falling object puncture cap body 1 falls to the inside intermediate position of the slow groove 6 on the slow piece 4, the impact end of the falling object can impact the corresponding position deviator 8 in the slow groove 6, when the falling object impacts the deviator 8, the impact end of the falling object can rotate through the dislocated deviator block 14 on the deviator 8 and the force application rethread deviator shaft 9 and deviator sleeve 10, thereby the impact end of the falling object is changed, thereby the direct puncture is avoided, so that the internal relevant mechanism of the cap body 1 can not be corrected in time, and the falling object is subjected to the fatal puncture condition on the human head.

When the thing that weighs down strikes dislocation diversion piece 14 on to deviator 8, the impact end of falling the thing can strike dislocation diversion piece 14 along the lateral wall of diversion cover 10, thereby make the impact end of falling the thing can strike the atress diversion board 17 that is close to diversion cover 10 lateral wall one end, thereby make the thing that weighs down strike and make corresponding position atress diversion board 17 produce deformation, mutually support through atress diversion board 17 and diversion cover 10 lateral wall, thereby impact the restriction to weighing down the thing, thereby greatly reduced weighs down the thing impact force.

When the thing that weighs down moves to both sides through last slow groove 6 of slow piece 4, when the thing that weighs down makes the one end of corresponding position slow piece 4 carry out the rotation that inclines, the auxiliary force piece 11 that corresponds the position can be oppressed to the corresponding position one end of slow piece 4, make auxiliary force piece 11 drive slow force area 13 closely laminate with the corresponding position lateral wall of slow piece 4, thereby make the thing that weighs down can correspond the supplementary piece 27 that hits that corresponds the position on slow force area 13 and carry out the slope and strike downwards, when the thing that weighs down strikes and lead to slow force area 13 to produce deformation, slow force area 13 can be dragged and assist power piece 11 to carry out the adaptation formula and rise and lift up, thereby make auxiliary force piece 11 pulling slow piece 4 to correspond position one end and carry out the lifting, thereby weigh down the impact direction of thing and carry out the lifting, thereby further the reduction takes place to the condition that the thing produces the injury to the user.

When the thing that weighs down strikes and to postpone on the piece 4 that the groove 6 is inside when producing the puncture to piece 4 that slows down, through hitting piece 25 and spiral connecting band 26 in the inboard interval on the piece 4 that slows down, when the thing that weighs down punctures to corresponding interval connection net 19 position, hit piece 25 through weighing down thing puncture end and well, make and weigh down thing puncture end and hit piece 25 and carry out synchronous operation, thereby make to hit on the piece 25 spiral connecting band 26 and can carry out the spiral parcel of annular with weighing down thing puncture end, thereby cushion the restriction to the lower power of weighing down of thing.

When the weight pierces through interval connecting network 19 and extends to the inside of delaying piece 4, because the weight is in the slope puncture basically, the weight puncture end of slope puncture can connect spring 20 with delaying the inside multiunit torsion of piece 4 and contact, connect the spiral structure of being difficult for the dislocation of spring 20 in the torsion, the puncture end of weight can buckle inside the clearance on torsion grafting spring 20, connect spring 20 to remove in driving the torsion through assaulting, connect spring 20 to go up spiral winding structure through the torsion and make the weight impact force reduce, simultaneously, make through torsion grafting spring 20's elasticity can drive the weight when the weight impact force exhausts and carry out the adaptation formula and resume, thereby greatly reduced the puncture force of weight.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
