Furthermore, a laser emitter is arranged on the circle center rotating rod, and an emitting end of the laser emitter faces one side of the fan-shaped area.
Furthermore, the laser emitter, the circle center rotating rod, the horizontal swing rod and the degree pointer are located on the same plane.
Further, the elbow clamp splice bottom is equipped with the sliding block, and in the linear slide fretwork hole of sliding block embedding, be equipped with the clamp splice gim peg on the sliding block.
Further, the included angle degree of the sector area is 45 degrees or 90 degrees.
During the use, place corresponding elbow according to elbow position scale, remove the elbow clamp splice, the elbow is all cliied on both sides, and the clamp splice gim peg is fixed, only the elbow both sides can normally be cliied, just can guarantee the position accuracy. And starting the laser emitter, rotating the circle center rotating rod and rotating the degree indicator to the angle position needing to be cut. The light emitted by the laser emitter is emitted onto the elbow, any angle found is marked by the marking pen according to the light, and then the elbow with any angle is cut according to the mark.
Compared with the prior art, the utility model the advantage be: the utility model discloses the cutting position of measurement arbitrary angle elbow that can be accurate has solved the problem that master relies on experience rule to cut arbitrary angle elbow precision. Simple structure easily operates: different arbitrary-angle scribers for the elbows of 90 degrees and 45 degrees are respectively made; the measurement angle is accurate: the laser ray has high precision and strong usability.
