It is fastenedly connected with shaft under the action of position cap and Fastener.
Further, the Fastener is clamp spring, and clamp spring is mounted on rocking arm clamping in limiting slot.
Further, the size of the limited cap is more than mounting hole, axial distance between limited cap and limiting slot with shake
The thickness of arm mounting hole is identical, limits it and moves up and down.
Further, the cross sectional shape of the cylinder be triangle, quadrangle, hexagon or octagon, preferably six
Side shape.
Further, the shaft is vertically arranged, and lower end is connected on the pedestal of travel switch ontology, and described shakes
Arm is vertical with shaft.
Further, the rocking arm is equipped with idler wheel, and the idler wheel is set to the opposite one end of mounting hole.
Further, the rocking arm is straight plate aluminum casting, and from mounting hole one end toward idler wheel one end, bar diameter gradually becomes
Carefully.
Compared with prior art, the upper end of the rocking arm mounting hole of the utility model and shaft is polygon, and passes through limit
Cap and Fastener fastening, cancel nut and bolt, increase the limit of polygon corner angle, avoid rocking arm from skidding, prevent rocking arm from falling off, limit
Rocking arm processed is freely rotated, and can guarantee that product is operating normally in case of shock, and the trip construction of switch is simple, manufacturing cost
It is low, conducive to promoting the use of.
