The specific embodiment
Embodiment: as shown in Fig. 1-4,: Special spanner for preventing screw cap from falling, comprise wrenching bar 9, handlebar 10 and spanner pullover 1, handlebar 10 is cylindrical, wrenching bar 9 is tubular construction, wrenching bar 9 tops are provided with horizontal circular hole, be equipped with handlebar 10 in circular hole, the two ends of handlebar 10 are provided with disconnecting prevention structure, described disconnecting prevention structure comprises the counterbore that arranges on handlebar 10, be provided with successively from the bottom to top anticreep back-moving spring 12 and anticreep steel ball 11 in counterbore, counterbore setting suitable for reading is exposed at the top of anticreep steel ball 11.Pullover 1 lower end endoporus 8 shapes of spanner and nut shape are suitable, are orthohexagonal endoporus 8 in the present embodiment.The top of spanner pullover 1 is provided with guide rod hole, is equipped with guide post 6 in guide rod hole, and the guide post 6 of spanner pullover 1 top is provided with anti-dropping locating device, and described anti-dropping locating device is flat shim 4 and the caging bolt cap 5 that is arranged on guide post 6.The lower end of guide post 6 is provided with magnetic chuck 2, is equipped with back-moving spring 3 on the guide post 6 between pullover 1 top of spanner and magnetic chuck 2; The pullover 1 end opening end face of spanner is provided with annular magnet 7.Magnetic chuck 2 is the 8-12 millimeter to the distance between spanner pullover 1 bottom, 10 millimeters of the present embodiment metas.Wrenching bar 9 is tube-shaped structure, and the size of wrenching bar 9 endoporus is convenient to mounting limit nuts 5 greater than caging bolt cap 5 sizes.
In narrow place, when needing to use Special spanner for preventing screw cap from falling to remove nut, spanner pullover 1 is aimed at bolt firmly depress magnetic chuck 2, until the pullover 1 orthohexagonal endoporus 8 cover upper cap nuts in lower end of spanner, then turning handle bar 10 loosen nut, at this moment annular magnet 7 adsorption gaskets, nut fall back on shank of bolt at ordinary times, nut is adsorbed by magnetic chuck 2, nut and magnetic chuck 2 rotate together and withdraw from shank of bolt, nut can not come off by magnetic chuck 2 absorption, has played the screw cap-falling-proof effect.
When needing nut is installed, nut is contained on the pullover 1 orthohexagonal endoporus 8 in lower end of spanner magnetic chuck 2 absorption nuts, then install, nut is tightened gradually, and shank of bolt compression magnetic chuck 2 is thrown off with nut, the decrement of magnetic chuck 2 guaranteed pullover can tightening nuts.
