The specific working process of the invention is as follows:
in operation, the optical fiber 23 of the present invention is detachably connected to the host housing 2 through the flange 26, and the optical fiber ferrule 28 is directly connected to the host housing 2, and by mounting the optical fiber 23 and the optical fiber ferrule 28 separately from each other, the size of the optical fiber ferrule 28 is not limited by the size of the optical fiber 23 and the flange 26, because if the optical fiber ferrule 28 is directly connected to the flange 26 and the size of the optical fiber ferrule 28 is larger, the bending diameter of the optical fiber ferrule 28 is larger, that is, the optical fiber ferrule 28 is not easily bent, and a large stress is generated during bending, so that the connection between the optical fiber 23, the optical fiber ferrule 28 and the flange 26 is broken or loosened, while the present invention only connects the optical fiber 23 with a smaller diameter to the flange 26, so that when the optical fiber 23 and the optical fiber ferrule 28 are bent, the bending of the optical fiber 23 is not limited by the bending stress of the optical fiber ferrule 28, the optical fiber 23 can slide relatively in the optical fiber sleeve 28, so that the optical fiber 23 cannot cause large bending stress to the flange 26 when being bent, and the flange 26 is prevented from being damaged;
meanwhile, because the bedside cabinet in front of the hospital bed is small in size, if the spectrometer body 1 and the optical fiber sleeve 28 are placed on the bedside cabinet and are easy to fall off, the optical fiber detector can store messy optical fibers 23 and the optical fiber sleeve 28, so that the optical fibers 23 and the optical fiber sleeve 28 are prevented from being stacked on the desktop at will and easily falling off, and the appearance is not influenced; in actual operation, the optical fiber 23 and the optical fiber sleeve 28 extending from the threading slot 22 are located at a position close to the bottom edge of the spool 29 and located between the two sets of mounting plates 24, the wire arranging rod 10 is located in the clockwise direction of the optical fiber 23 and the optical fiber sleeve 28, at this time, the hollow cylindrical tube 6 can be rotated clockwise towards the limiting disk 4 by the rotating handle 5 at the edge of the hollow cylindrical tube 6, the horizontal round rod 16 can drive the L-shaped connecting rod 3 and the wire arranging rod 10 to move clockwise towards the limiting disk 4, the wire arranging rod 10 can stir the optical fiber sleeve 28 and the optical fiber 23 and enable the optical fiber 23 to be embedded between the two sets of limiting disks 4 in the rotating process, the length of the optical fiber 23 and the optical fiber sleeve 28 in the invention is slightly larger than the perimeter size of the spool 29, when the wire arranging rod 10 is completely accommodated at the edge of the spool 29, the hollow cylindrical tube 6 can be pressed at this time, so that the clamping column 7 at the inner side end of the hollow cylindrical tube 6 is embedded in the clamping groove 8 at the outer wall of the limiting disk 4, therefore, the positions of the L-shaped connecting rod 3 and the wire arranging rod 10 are fixed, and when the clamping column 7 and the clamping groove 8 are in a splicing state, the spring compression tube 14 positioned inside the hollow cylindrical tube 6 is extruded by the rectangular push plate 15, and then air inside the spring compression tube 14 enters the top of the cylindrical groove 9 through the airflow channel 13, so as to push the piston plate 18 and the vertical movable rod 19 to move downwards, so that the wire arranging rod 10 is pressed on the surface of the optical fiber sleeve 28, the optical fiber 23 and the optical fiber sleeve 28 are prevented from being wound on the surface edge of the winding disc 29, when the optical fiber 23 and the optical fiber sleeve 28 need to be unwound, the hollow cylindrical tube 6 is pulled outwards at the moment, the clamping column 7 at the end part of the hollow cylindrical tube is separated from the inside of the clamping groove 8, at the moment, the hollow cylindrical tube 6 moves towards the direction far away from the horizontal round rod 16, and the spring compression tube 14 fixedly connected with the rectangular push plate 15 stretches, the spring compression tube 14 will draw air from the top of the cylindrical groove 9, and the piston plate 18 will move upward under the action of the spring fixedly connected with the spring, and at this time, the wire arranging rod 10 is lifted upward and will not press the optical fiber 23 and the optical fiber sleeve 28, so that the optical fiber 23 and the optical fiber sleeve 28 can be unwound by rotating the wire arranging rod 10.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
