Match somebody with somebody, be easy to the integrally connected of eccentric shaft and spacer, and further pass through the off-centre operation and cable anchor ear phase of eccentric rotation axis
Support, so as to ensure the fixed position of cable anchor ear.
The outer-hexagonal section of the eccentric shaft is provided with handle, i.e., the outer-hexagonal of U-shaped handle two ends respectively with both sides eccentric shaft
Section connection.Said structure is easy to by handle eccentric rotation axis, and then drives the rotation of spacer, realizes the work(of above-mentioned eccentric shaft
Energy and technical purpose, i.e. handle use the structure of integral type.
The handle is special-shaped handle of the two ends provided with die nut mouthful, the hexagonal mouthful of handle and the outer-hexagonal section of eccentric shaft
Engagement.So that handle is used as spanner, regulation simultaneously for both sides eccentric shaft when in use.
The waist-shaped hole both sides plate body of the supporting plate is in isosceles triangle respectively, and the triangle plate body of inner side is higher than outside
Triangle plate body, eccentric shaft is located at the end corner side of triangle plate body.Said structure is easy to reduce the space hold of supporting plate, and
It is easy to checking for state in supporting plate.
Waist-shaped hole is provided with the supporting plate and the mode connects for screw of bottom plate, said structure is easy to the regulation of supporting plate.
Reasonable in design of the present invention, assembling, using, it is easy to adjust, space hold is small；Its electricity mainly as switch cubicle
Cable anchor ear safety device is used, and the structure of like product is improved.
