Have gusset on described connecting base, described gusset is positioned at the outside of described connecting base, and corresponding with the position of described cone-shaped plug, and the pillar of described cone-shaped plug links to each other with described gusset through the seat board of described connecting base.

At the center line of described gusset center line and described connecting base, its projection angle of cut in vertical state.

Be connected part at described pillar with described seat board, on the seat board of described pillar two sides, have the aperture.

In the joint of described cone-shaped plug and described pillar, on the outer surface of described cone-shaped plug, have the plane, on the internal surface of described cone-shaped plug two sides, have cavity.

Described connection set is equipped with the guide plate of making of metal by plastic production in the seat board inboard of described connecting base.

The utility model adopts the connecting base in U-shaped cross section to be clamped on the crane span structure unit, utilize the angle of connecting base, two adjacent straight crane span structure unit can be connected with rising or decline angle, on connecting base, has cone-shaped plug, connecting base is clamped in two adjacent ends, crane span structure unit, cone-shaped plug is extend into corresponding in mounting hole on the sidewall of each crane span structure unit, knock with mallet then, the cone-shaped plug tensioner is held in this mounting hole, can be with two adjacent crane span structure unit to rise or the connection of decline angle form, connection set can be used plastic production, and its weight is greatly alleviated, its connection saves time and saves trouble, and need not screw bolt and nut.

In sum, it is fixing that the utility model adopts Placement to be that cone-shaped plug knocks, and makes cable testing bridge can improve speed when mounted, reduces operation fatigue, adopts this connection set of plastic production, makes it in light weight, makes overall cost reduce reliable in quality.The utility model is suitable for using when cable testing bridge rises or descends.
