Claims

[Scope of Claim for Utility Model Registration] A case-shaped branch line standard determination device that houses a spiral tape measure and is equipped with a bubble-type angle meter for measuring the branch line attachment angle to judge various standards in the branch line process, Inside the main body, there is a tape measure chamber partitioned by a substantially U-shaped dividing frame connected to one side plate, and a stopper is fixed to the tip stored in the tape measure chamber and pulled out from a horizontal hole provided in the case main body. and a bubble-type angle that is fitted into a groove recessed in the side or top surface of the case body and displays the branch line attachment angle when the bottom of the case body is brought into contact with the telephone pole branch line. a branch line type determining section recessed in the bottom surface of the case body toward both sides and comprising a plurality of grooves corresponding to the diameter widths of the various branch lines; and a surface of the tape measure that determines the attachment angle of the various branch lines. a buried rod depth determination section that displays a scale, and displays a specified exposed length of the buried rod at the lower end of the branch line with the unit scale of the tape measure corresponding to the installation angle scale; A curved pole angle in which the curved pole angle scale of the railway line is displayed, and the mutual interval length between positions of a certain length of electric lines on both sides of the utility pole is displayed on the unit scale of the tape measure corresponding to the curved pole angle scale. A determination unit, characterized in that it determines various standards corresponding to branch line attachment angles of various utility pole branch lines,
Various standard judgment devices for utility pole branch lines.
