Three stress points of upper plate, are changed into two stress of lower plate both sides by the mounting hole for hingedly installing suspension clamp of side
Point, it is simple in structure, centre-height is reduced, in-site installation is convenient for.The suspension clamp installed in lower plate can automatically adjust left and right
The stress balance of both sides, facilitates conducting wire, additionally it is possible to automatically adjust tower position height difference and conducting wire carry out it is equal after ice caused by imbalance,
Ensure serial type steadily safety.
Further, upper plate and lower plate use veneer and double plate structure respectively so that and it is hinged more stable reliable, do not have to weldering
Binding structure, interchangeability is good, easy for installation.
Description of the drawings
Fig. 1 is that the structure of installation suspension clamp in connection gold utensil in of the invention three specific embodiments for becoming two connection gold utensils is shown
It is intended to；
Fig. 2 is the left view of Fig. 1.
Specific implementation mode
Embodiments of the present invention are described further below in conjunction with the accompanying drawings.
The three of the present invention become the specific embodiment of two connection gold utensils, and as shown in Figure 1 to Figure 2, three two connection gold utensils of change include
Upper plate 1 and lower plate 2 setting up and down, the lower part of upper plate 1 is hinged by the first bolt 3 with the top of lower plate 2, and upper plate 1 is veneer
Structure, lower plate 2 are double plate structure, and lower plate 2 includes time interval two scoreboards disposed in parallel, and hinged place upper plate 1 is located at two points
