In the present embodiment, connecting lever ontology 110 connects the diameter of the width and installation sleeve 120 of one end of installation sleeve 120
Match so that connecting lever ontology 110 and the link position of 120 both sides of installation sleeve seamlessly transit.Along the length of connecting lever ontology 110
Direction is gradually reduced to one end far from installation sleeve 120, the width of connecting lever ontology 110, and connecting lever ontology 110 is far from installation sleeve
120 one end processing is circle, and staff is facilitated to operate.
Specifically, the one end of connecting lever ontology 110 far from installation sleeve 120 is provided with handle hole 111, the handle hole 111
With the round concentric of 110 end of connecting lever ontology.
The axis direction length of installation sleeve 120 is more than the thickness of connecting lever ontology 110, can increase and disconnecting switch main shaft
200 contact area provides more firm support for the rotation operation of connecting lever ontology 110.
Specifically, it further includes connector 130 that connecting lever 100 is driven in the present embodiment；Installation sleeve 120 has prolongs along its axial direction
Stretch the elongated slot 121 of perforation；Connector 130 is for connecting the barrel that installation sleeve 120 is located at 121 both sides of elongated slot, so that installation set
Cylinder 120 is held tightly on disconnecting switch main shaft 200.
Installation sleeve 120 has mounting hole, internal spline is provided in mounting hole, for coordinating disconnecting switch main shaft 200
External splines.Installation sleeve 120 is for holding tightly in disconnecting switch main shaft 200 in the present embodiment, realizes internal spline and external splines
Cooperation in order to facilitate the installation of and adjusts position of the installation sleeve 120 on disconnecting switch main shaft 200, is installed in the present embodiment
Elongated slot 121 is offered on sleeve 120, is held tightly for installation sleeve 120 and is provided adjusting surplus in disconnecting switch main shaft 200.
Specifically, connector 130 is connected to the barrel positioned at 121 both sides of elongated slot of installation sleeve 120, installation sleeve 120
The barrel positioned at 121 both sides of elongated slot it is radial radially adjacent to the barrel of so that installation sleeve 120 under the action of connector 130
It shrinks, is fastenedly connected in what is both on disconnecting switch main shaft 200, realized until installation sleeve 120 is held tightly.It is driven when needing to adjust
When the installation site of connecting lever 100, fastening of the connector 130 to installation sleeve 120 is released, installation sleeve 120 is adjusted and is keeping apart
Close the position on main shaft 200.
Further, the barrel positioned at the installation sleeve 120 of 121 side of elongated slot is provided with the first connecting hole, and the other side is set
There is the second connecting hole；First connecting hole is through-hole, and connector 130 is connect across the first connecting hole with the second connecting hole.
One end of connector 130 passes through the first connecting hole and the second connecting hole to coordinate, and passes through adjusting connector 130 and second
Connection relation between connecting hole, thus it is possible to vary the width of elongated slot 121, and then the inner diameter size of installation sleeve 120 is adjusted, reduce
The internal diameter of installation sleeve 120 enables installation sleeve 120 to hold tightly on disconnecting switch main shaft 200, realize driving connecting lever 100 with
Disconnecting switch main shaft 200 is fastenedly connected.
Preferably, connector 130 is bolt, and the external screw thread to match with bolt is provided in the second connecting hole.When installation,
Connector 130 is set into female one end and passes through the first connecting hole, by elongated slot 121, along the internal thread of the second connecting hole
The second connecting hole is screwed in, until installation sleeve 120 holds disconnecting switch main shaft 200 tightly.
Further, the quantity of connector 130 is two, and the axis direction along installation sleeve 120 is extended, Neng Goujin
One step improves the connective stability of driving connecting lever 100 and disconnecting switch main shaft 200.
In addition, present invention implementation also provides a kind of disconnecting switch, including Switch main body 300, it is arranged on the Switch main body 300
There is above-mentioned disconnecting switch driving structure, all advantageous effects of the disconnecting switch driving structure can be obtained, disclosure satisfy that more
Work requirements, the facility of bigger is provided for staff the operation of disconnecting switch.
Finally it should be noted that：The above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Present invention has been described in detail with reference to the aforementioned embodiments for pipe, it will be understood by those of ordinary skill in the art that：Its according to
So can with technical scheme described in the above embodiments is modified, either to which part or all technical features into
Row equivalent replacement；And these modifications or replacements, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
