the two adjacent arc-shaped pads (6) are positioned on the right side of the connecting rod (51), the opposite surfaces of the two adjacent arc-shaped pads are respectively and vertically provided with a through groove (7), and the opening at the top end of each through groove (7) is larger than the opening at the bottom end of each through groove (7); when the arc-shaped pad (6) clamps the optical fiber, the arc-shaped pad (6) is provided with the through groove (7) with a large upper part and a small lower part on the surface of the arc-shaped pad (6), so that the optical fiber can be clamped into the arc-shaped pad (6) from the upper end of the through groove (7) conveniently, the lower end of the through groove (7) is small, the optical fiber can be clamped by the arc-shaped pad (6) when being arranged at the lower end of the through groove (7), and finally the arc-shaped pad (6) at the through groove (7) clamps the optical fiber, so that the clamping effect on the optical fiber is further improved, and the stability between;
a sliding groove (8) is formed in the transverse plate (41) on the right side of the clamping groove (42), the end part of the connecting rod (51) at the forefront can rotate in the sliding groove (8), and a clamping plate (43) on the right side of the sliding groove (8) is extruded; after the transverse plate (41) on the right side of the clamping groove (42) is provided with the sliding groove (8), the end part of the connecting rod (51) can rotate into the sliding groove (8) when rotating, so that the transverse plate (41) at the sliding groove (8) has a supporting force for the connecting rod (51), and the connecting rod (51) has a supporting force for the clamping plate (43), thereby preventing the joint between the clamping plate (43) and the transverse plate (41) from bearing larger force when more optical fibers are clamped in the clamping plate (43), causing the deformation of the hinged part of the clamping plate (43) and influencing subsequent use;
the right side of the free end of the clamping plate (43) is fixedly connected with a fixing rod (9), the end part of the fixing rod (9) is fixedly connected with an elastic ball (10), the clamping plate (43) close to the right end of the clamping groove (42) is provided with a fixing hole (11), and the elastic ball (10) can be inserted into the fixing hole (11) along with the rotation of the clamping plate (43) and is used for fixing the clamping plate (43); exert external force with cardboard (43) and make cardboard (43) rotate draw-in groove (42) in, promote cardboard (43) with strength, make in elastic ball (10) fills in fixed orifices (11), make the fixed effect of cardboard (43) better, prevent when adjusting the optic fibre line of top, cardboard (43) of below are not hard up.
