1. A tape structure comprising:
a first body, a first laser body, and a second laser body;
wherein:
the first body has an end provided with a stop portion;
a measured object rests on the stop portion;
the stop portion is provided with a first surface facing the first body;
the first surface is provided on an end face of the stop portion;
the stop portion is provided with a second surface opposite to the first surface;
the first surface is provided with multiple grooves;
the first body is made of resilient material;
the stop portion is made of hard material;
the stop portion is a single element;
the stop portion is assembled to the first body;
the first laser body is provided on the first surface and includes multiple laser lines distributed on the first surface;
the first surface distributed with the first laser body forms a first friction face;
the first friction face increases a friction force between the first surface and the measured object when the first surface touches the measured object, to prevent the stop portion from slipping from the measured object;
the second laser body is provided on the second surface and includes multiple laser lines distributed on the second surface;
the second surface distributed with the second laser body forms a second friction face;
the second friction face increases a friction force between the first surface and the measured object when the first surface touches the measured object, to prevent the stop portion from slipping from the measured object;
the first laser body on the first surface and the second laser body on the second surface are identical or different;
the first laser body and the second laser body are made identical or different by features of a laser process;
the stop portion is provided with the first laser body and the second laser body and formed with the first friction face and the second friction face;
the first laser body and the second laser body are formed by the laser process;
the first laser body and the second laser body are provided on the stop portion;
the first laser body and the second laser body are formed on a whole surface or a partial surface of the stop portion by a working machine during a laser process;
the whole surface or partial surface of the stop portion is provided with the first friction face and the second friction face which are formed by the laser process, including peeling, coloring, concentration, or carbonization;
each of the first friction face and the second friction face is a rough surface with particles;
the first friction face and the second friction face increase a contact friction force between the stop portion and the workpiece to prevent the workpiece from slipping from the stop portion;
the first laser body and the second laser body are provided on the stop portion and formed with the first friction face and the second friction face;
the first friction face covers at least one third of the first surface;
the second friction face covers at least one third of the second surface;
when the first friction face is provided on the first surface, the first laser body includes multiple first friction faces, and the first friction faces are distributed on the first surface;
when the second friction face is provided on the second surface, the second laser body includes multiple second friction faces, and the second friction faces are distributed on the second surface;
when the first friction face is provided on the first surface, the first laser body includes multiple first friction faces, and the first friction faces are arranged obliquely relative to the stop portion;
an angle of ten degrees to seventy degrees is defined between each of the first friction faces and a side of the stop portion;
the angle has an optimum value of forty-five degrees;
when the second friction face is provided on the second surface the second laser body includes multiple second friction faces, and the second friction faces are arranged obliquely relative to the stop portion;
an angle of ten degrees to seventy degrees is defined between each of the second friction faces and a side of the stop portion;
the angle has an optimum value of forty-five degrees;
the first friction faces are arranged linearly relative to the stop portion;
the first friction faces and the stop portion are parallel with each other; and
the first friction faces are arranged transversely relative to the stop portion.
