Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Fig. 1, Fig. 2, shown in Fig. 5 and Fig. 6, piston guide covering device, comprise piston guide cover 1, housing 2, chi spring 3, handle 4 and keeper 5, described piston guide cover 1 comprises fairlead body 11, described fairlead body 11 one end is stiff end 12 other end is free end 13, described housing 2 comprises enclosure body 21, opening 22 is provided with on the upside of described enclosure body 21, described enclosure body 21 is provided with locating hole 23, this locating hole 23 is positioned at enclosure body 21 both sides and corresponding setting, described enclosure body 21 side-wall outer side is also fixedly installed handle 24, described enclosure body 21 is made for light material, especially be plastics or aluminium alloy.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, fairlead body 11 is arranged on opening 22 region, and described stiff end 12 is fixed in enclosure body 21, and described free end 13 extends in enclosure body 21, keeper 5 comprises thread spindle 51 and nut 52, described thread spindle 51 is through being fixed in enclosure body 21 by nut 52 after the corresponding locating hole 23 arranged, the corresponding piston guide cover 1 of this keeper 5 is arranged, described chi spring 3 is combined by two chi springs arranged side by side and to form and one end to be fixedly connected with the other end extends to enclosure body 21 and be fixedly connected with handle 4 with keeper 5 outward by opening 22, described chi spring 3 is fixedly installed projection, the free end 13 of described chi spring 3 and fairlead body 11 is fixedly connected with at this projection place and free end 13 can be driven to move, described projection opposed free ends 13 is positioned at the side near handle 4.
