Further, described axle is multidiameter, and the second flange base is pressed on multidiameter.
Further, it is provided with sealing member between the shaft shoulder and second flange base of described axle.
Further, it is provided with sealing member between sidewall and second flange of described axle.
Further, described first flange base edge is inverted to form flange, and cushion block is arranged on this flange.
Further, described handle is arranged on axle top by bolt.
Further, offering the groove that can accommodate cushion block bottom described axle, cushion block embeds in this groove, is fixed with axle by cushion block by the pin inserted from axle sidewall.
Further, described earth plate is connected by two bolts and cushion block are fixing.
CVT of the present utility model presses grounding switch, axle is fixed in another flange by flange screw, handle and earth plate are separately fixed on axle, only need during maintenance to take off the securing member between two flanges, can take off the flange being enclosed within axle and the parts such as axle, handle are replaced, installation Renewal process is without uncapping, convenient and swift, without breakseal structure and simple to operation, it is simple to promote the use of.
Further, described axle is multidiameter, and the second flange base is pressed on multidiameter, it is simple to the installation between flange and axle and sealing.
Further, being provided with sealing member between the shaft shoulder and second flange base of described axle, be provided with sealing member between sidewall and second flange of axle, grounding switch is provided with multi-sealed, good seal performance, is difficult to oil leakage phenomenon occur.
Accompanying drawing explanation
Fig. 1 is the structural front view of prior art；
Fig. 2 is structural representation of the present utility model；
Wherein: 1 is the first flange；2 is the second flange；3 is axle；4 is handle；5 is cushion block；6 is earth plate.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail:
See Fig. 2, CVT of the present utility model presses grounding switch, mainly includes the first flange 1；Second flange 2；Axle 3；Handle 4；Cushion block 5；Earth plate 6, wherein the first flange 1 is welded on oil tank wall, is used for fixing the second flange 2 and other assembly；Second flange 2 is with cylindrical cavity, axle 3 is connected through the first flange 1 is fixing with the cushion block 5 being arranged on the first flange 1 bottom, second flange 2 is enclosed within axle 3 and embeds in the first flange 1 and fixed with the first flange 1 by axle 3, axle 3 can rotate relative to the second flange 2, handle 4 is arranged on axle 3, and earth plate 6 is positioned at fuel tank and fixing with cushion block 5 is connected；Swing handle 4, drives earth plate 6 to move by axle 3 and cushion block 5, it is achieved dividing and conjunction of grounding switch.
Earth plate is the moving contact of disconnecting link, and handle, axle and cushion block form drive mechanism, swing handle during operation, drives earth plate motion, it is achieved dividing and conjunction of grounding switch.
