Embodiment Construction
[0013] A cylinder 2 is made of hard transparent materials, such as transparent glass, transparent hard plastic, etc., which can withstand pressure and have relatively small (negligible) deformation caused by pressure; one end of the cylinder 2 passes through The threads and sealing gaskets are connected with the sealing cap 1, and the realization of the sealing connection between the threads and the sealing gaskets is a prior art, which will not be repeated here; the other end of the cylinder 2 is covered with a grid cap 8, which is formed by a grid The flat plate is composed of a rubber cylinder. The grid plate has a central hole and an edge round hole. The two holes are connected by a long strip of solid parts. The edge round hole is connected to the rubber cylinder. The rubber cylinder is made of rubber. The elasticity of muscle is enclosed within the other end of cylinder 2. The outer surface of cylinder 2 has a millimeter scale along the length direction.
