The fiber holding clip 40 may be attached to the work table 10 by glue, and specifically, the installation method of the fiber holding clip may include the steps of: detachably connecting a connecting and positioning mechanism of a positioning tool to the side part of a workbench 10 in the grating measurement system; gluing the adhesive surface of the optical fiber fixing clamp 40 to form a glue-coated surface, placing the glued optical fiber fixing clamp 40 in a guide positioning mechanism 51 of a positioning base 50, wherein the glue-coated surface of the optical fiber fixing clamp 40 faces to the workbench 10; pushing the optical fiber fixing clamp 40 towards the workbench 10 along the guiding and positioning mechanism 51 until the glue coating surface of the optical fiber fixing clamp 40 is in contact bonding with the side part of the workbench 10; after the glue on the glue spreading surface is cured, the connection between the connecting and positioning mechanism and the workbench 10 is removed, and the positioning tool is taken down outwards along the guiding direction of the guiding and positioning mechanism 51.

Specifically, in this embodiment, as shown in fig. 5, when the guiding and positioning mechanism 51 is a guiding hole, the hole wall of the guiding hole may be provided with an inward-concave glue overflow groove 52, the extending direction of the glue overflow groove 52 is the same as the extending direction of the guiding hole, and two ends of the glue overflow groove 52 are arranged in a penetrating manner. The optical fiber fixing clamp 40 can be connected to the side part of the workbench 10 or the workbench 10 in an adhesive manner, when the adhesive face of the optical fiber fixing clamp 40 is dispensed with too much adhesive, the optical fiber fixing clamp 40 is inserted into the guide hole and adhered to the side part of the workbench 10 or the workbench 10, the excessive glue on the glue coating face of the optical fiber fixing clamp 40 is extruded to flow out along the glue overflow groove 52, thereby ensuring the adhesive adhesion degree of the optical fiber fixing clamp 40 and the side part of the workbench 10 or the workbench 10, reducing the extrusion of the excessive glue into the gap between the optical fiber fixing clamp 40 and the guide hole, and leading to the condition that the two can not take down the positioning base 50 due to mutual adhesion. After the optical fiber fixing clamp 40 is adhered to the side part of the workbench 10, a certain curing time is needed, and in the glue curing process, the positioning tool is kept installed on the side part of the workbench 10, so that the optical fiber fixing clamp 40 is limited and protected, and the phenomenon that the optical fiber fixing clamp 40 inclines under the action of self gravity or external force and even falls off in the glue curing process is reduced; and after the glue is solidified, the positioning tool is detached.
