The utility model provides a solve the shortcoming that exists among the prior art, provide a seal head division board laying-out measuring tool, including first bracing piece, second bracing piece, slip fixed block A, slip fixed block B, first telescopic link, second telescopic link, elastic connection area and laser range finder, the rectangle structure has been connected through first telescopic link and second telescopic link respectively to first bracing piece and the parallel both ends of second bracing piece, sliding connection has slip fixed block A and slip fixed block B on the first bracing piece, slip fixed block A is connected through elastic connection area with the below of slip fixed block B, be equipped with laser range finder on the second bracing piece.

To the further description of the present invention, the laser range finder is fixed to the side wall of the second support rod through the suction cup.

To the description of the present invention, the maximum stretching length of the elastic connection band is greater than the length of the first supporting rod.

To the further description of the present invention, the sliding fixing block a is the same as the sliding fixing block B.

To the utility model discloses a further description, first telescopic link is the telescopic link with the second telescopic link is the same.

It is right to the further description of the utility model, the length of first bracing piece and second bracing piece is greater than the diameter that needs the measuring head.

Right the utility model discloses a further description, laser range finder is built-in angle sensor's laser range finder.

For further description of the present invention, the second support rod is engraved with scale lines on its surface.

By adopting the technical scheme, the method has the following beneficial effects:

the utility model discloses simple structure, convenient to use, through upwards with the head opening, the outside edge that first bracing piece passed the centre of a circle of head is fixed in the head through slip fixed block A and slip fixed block B, because slip fixed block A is connected by elastic connection area with slip fixed block B, slip fixed block A and the difficult slip of slip fixed block B, according to the offset distance of the flexible first telescopic link simultaneously of width requirement and second telescopic link control laser range finder and first bracing piece to record laser distance, type the data of laser range finder into numerical control cutting machine and cut, the utility model discloses can measure the camber of the various heads of diameter variation in size, it is nimble convenient, easy operation has reduced workman's intensity of labour, has shortened the preparation time of interior division board.
