The metal layer is pressed through the adjusting rod 53, and the elastic layer (waterproof sealing material) forms good sealing and isolating operation on the cable part, the optical cable part and the joint part, so that the elastic layer forms very tight attaching effect with the cable part and the optical cable part, and good sealing and isolating operation of moisture is generated. Furthermore, adjustment rods are provided at a plurality of positions, and the left gasket part 41 of the first gasket assembly 31 and the left gasket part of the second gasket assembly 31 are respectively pressed together by the corresponding adjustment rods 61, so that the closed pressing and bonding at the end is formed, and the closing and isolating operation for the cable part 11 is further improved. The right gasket part 45 of the first gasket assembly 31 and the right gasket part of the second gasket assembly 32 generate a pressing operation of involution under the action of the corresponding adjusting rod 65, so that a closed pressing fit at the end is formed, and the closed isolation operation of the optical cable part 12 is further improved. In addition, the joint gasket part 43 of the first gasket assembly 31 and the joint gasket part 43 of the second gasket assembly 32 respectively realize the involution extrusion operation on the joint part 12 through the adjusting rod 63, so that more stable closing and isolating operation is performed, a very good fixing effect is formed on the cable part, the optical cable part and the joint part, good closing operation is performed on moisture isolation of the cable part, the optical cable part and the joint part, and the service life is prolonged.

Thus, a shim assembly having only one arcuate portion is provided, and the shim assembly 70 is added to the retaining groove with excess clearance until the adjustment bar is tightened after application. It is clear that such a shim pack 70 can be used in a plurality of superimposed numbers, either in the first or in the second holding groove.
As shown in fig. 9, another lateral adjustment lever 76 is provided at a middle position of the fastening member 23, and the lateral adjustment lever 76 performs a pressing sealing operation in a lateral direction with respect to the fitting intersection formed by the left gasket portions of the first and second gasket assemblies at the lateral position, thereby increasing such fixing and sealing fitting operations. In a specific using method, the left gasket part 41 of the first gasket assembly 31 is pressed through the first adjusting rod 61, and the left gasket part of the second gasket assembly 32 is pressed through the second adjusting rod at the same time, so that the two left gasket parts form a joint pressing cross to form a sealing end, and at the moment, the sealing end forms a further pressing sealing operation on the cable part in the transverse direction through the action of the transverse adjusting rod 76, and the tightness and the sealing performance are further improved. Obviously, a lateral adjustment lever may also be provided on one side of the cable section.
Although the present invention has been described with reference to the preferred embodiments, it should be understood that the scope of the present invention is not limited thereto, and those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit and scope of the present invention.
