The specific embodiment
Embodiment: shown in Fig. 1-3, the screw cap-falling-proof box spanner comprises connector 8 and socket head 1, and connector 8 is a cylindrical structural, is provided with the square opening 10 that is used to plug spanner handle in the connector 8 vertically.Socket head 1 lower end endoporus, 4 shapes and nut shape are suitable, are regular hexagon endoporus 4 in the present embodiment.The top of socket head 1 is provided with guide rod hole, is equipped with guide post 7 in the guide rod hole, and the guide post 7 of socket head 1 top is provided with the anticreep positioner, and in the present embodiment, the anticreep positioner is the flat shim 5 and caging bolt cap 6 that is arranged on the guide post 7.The lower end of guide post 7 is provided with magnetic chuck 2, is equipped with back-moving spring 3 on the guide post 7 between socket head 1 top and the magnetic chuck 2.Inlay on the socket head 1 end opening end face and be provided with annular magnet 9.Magnetic chuck 2 is the 8-12 millimeter to the distance between socket head 1 bottom, is 10 millimeters in the present embodiment.The square opening size of connector 8 is convenient to install caging bolt cap 6 greater than caging bolt cap 6 sizes.
In narrow place, when needing to use the screw cap-falling-proof box spanner to remove nut, pinch bar is installed on the connector 8; Socket head 1 is aimed at bolt firmly depress telescopic sucker 2, up to orthohexagonal endoporus 4 cover upper cap nut, the rotating spanner handle loosen nut then of socket head 1; At this moment annular magnet 9 adsorption gaskets; Nut fall back on shank of bolt at ordinary times, nut is by magnetic iron pan 2 absorption, nut and magnetic iron pan 2 rotate together and withdraw from shank of bolt; Nut can not come off by 2 absorption of magnetic iron pan, has played the screw cap-falling-proof effect.
When needing nut is installed, nut is contained on the socket head 1, magnetic iron pan 2 absorption nuts are installed then, and nut is tightened gradually, and shank of bolt compression magnetic iron pan 2 is thrown off with nut, and the decrement of magnetic iron pan 2 has guaranteed that socket head 1 can tightening nuts.
