When the two adjusting devices 10 are located at the releasing position, the distance between the two adjusting devices 10 is larger, which can facilitate the installation or the removal of the flat lens 20. When the two adjusting devices 10 are located at the fixed positions, the distance between the two adjusting devices 10 is small, for example, the fixed positions may be the positions where the adjusting devices 10 are located when the flat lens 20 contacts the inner side wall of the accommodating chamber 11, and the flat lens 20 may be fixedly clamped by the two adjusting devices 10 in the first direction a, so that the reliability of fixing the flat lens 20 may be improved.

Therefore, the two adjusting devices 10 can move between the releasing position and the fixing position, and the openings 111 of the accommodating cavities 11 are opposite to each other, so that the flat lenses 20 are conveniently installed inside the accommodating cavities 11, the flat lenses 20 are conveniently clamped, the cutting efficiency of the flat lenses 20 is improved, the relative displacement between the upper and lower adjacent flat lenses 20 is avoided, and the cutting precision is improved. Meanwhile, the accommodating cavities 11 of the two adjusting devices 10 arranged in this way can accommodate and mount the flat lenses 20 with different sizes, and the application range of the fixing mechanism 100 can be widened.

The first sidewall 112 may be directly connected to the second sidewall 113, or indirectly connected. For example, the first side wall 112 and the second side wall 113 are directly connected at an end facing away from the opening 111 in the accommodating chamber 11, the included angle between the first side wall 112 and the second side wall 113 is 90 °, and the first side wall 112 and the second side wall 113 can position the flat lens 20 installed inside the accommodating chamber 11 with reference to the plane of the first side wall 112 and the second side wall 113.

Therefore, the first side wall 112 and the second side wall 113 of the accommodating cavity 11 are perpendicular to each other and connected to each other, and the limit of the accommodating cavity 11 on the flat lens 20 installed inside the accommodating cavity 11 can be increased, so that a plurality of flat lenses 20 can be stacked in a direction perpendicular to the flat lens 20, and the edge of the stacked flat lens 20 can be flush with the accommodating cavity 11, so that the flat lens 20 can maintain good cutting precision in the cutting process.

As shown in fig. 1, each adjusting device 10 includes: a bottom plate 12 and an adjusting piece 13, wherein the adjusting piece 13 is movably arranged on the bottom plate 12, and the accommodating cavity 11 is formed on the adjusting piece 13.

Specifically, the left-right direction of the adjusting device 10 is a first direction a, the direction of the adjusting device 10 perpendicular to the bottom plate 12 is a second direction B, which is also the up-down direction of the adjusting piece 13, the bottom plate 12 is located below the adjusting piece 13, the adjusting piece 13 can be fixed on the bottom plate 12 through a bolt, and the bottom plate 12 is provided with a through hole for the bolt to pass through. The adjusting members 13 can move in the first direction a relative to the base plate 12, the two adjusting members 13 approach each other in the first direction a, so that the flat lens 20 can be clamped, and the two adjusting members 13 move away from each other in the first direction a, so that the flat lens 20 can be disassembled.

One end of the first adjustment lever 15 abuts against the adjustment member 13 so that the first adjustment lever 15 can push the adjustment member 13 to move from the release position in the first direction a to the fixing position. The first elastic restoring member a is gradually compressed in the process of moving the adjusting member 13 from the releasing position to the fixing position, and the amount of compression is always within a range capable of restoring the elastic deformation.

Thus, by providing the fixing plate 14, the first guide bar 16 and the first adjustment bar 15 penetrating the fixing plate 14, when adjusting the first adjustment bar 15, the first adjustment bar 15 can abut against one end of the adjustment piece 13 away from the opening 111, so that the adjustment piece 13 is moved from the release position to the fixing position, thereby clamping the flat lens 20 inside the accommodating chamber 11.

Further, the first adjusting lever 15 is screw-coupled to the fixing plate 14, and rotating the first adjusting lever 15 pushes the corresponding adjusting member 13 from the releasing position to the fixing position. That is, the first adjusting lever 15, which is fixedly connected to the adjusting part 13, can move two adjusting parts 13, which are far away from each other, relatively closer to each other.

Therefore, the first adjusting rod 15 is in threaded connection with the fixing plate 14, the connection mode is simple, and the high displacement precision is achieved, so that the adjusting piece 13 can be accurately moved from the releasing position to the fixing position.

Specifically, a mounting member 131 is provided at a side of the adjusting member 13 adjacent to the fixing plate 14, and the first guide bar 16 is fixed to the adjusting member 13 by the mounting member 131, and the mounting member 131 has a hardness greater than that of the adjusting member 13.

As shown in fig. 2, the adjusting member 13 is provided with a mounting groove at a side close to the fixing plate 14, the mounting member 131 is positioned in the mounting groove and fixed to the mounting groove, and the mounting member 131 may be provided with a plurality of through holes for the first guide bar 16 to pass through and fix. When the adjusting members 13 are moved from the releasing position to the fixing position, one end of the first adjusting lever 15 is provided with a first adjusting handle 151, and the other end is stopped against the mounting member 131, and by adjusting the first adjusting handle 151, the first adjusting lever 15 is stopped against the mounting member 131 to make the two adjusting members 13 approach each other, or one of the adjusting members 13 moves toward the other adjusting member 13, so as to fix the plate lens 20 mounted in the accommodating chamber 11.

For example, the first guide bar 16 may be rotationally engaged with the fixed plate 14. At this time, the end of the first guide bar 16 may be fixed to the mounting member 131, and the first guide bar 16 pushes the mounting member 131 to bring the two adjusting members 13 close to each other to clamp the plate lens 20, and moves the two adjusting members 13 away from each other by the first elastic restoring member a to move the adjusting members 13 back and forth between the release position and the fixing position.

Alternatively, the first guiding rod 16 may be rotatably connected to the mounting member 131, that is, after the end of the first guiding rod 16 close to the mounting member 131 is fitted to the mounting member 131, the first guiding rod 16 may rotate around the axial direction of the first guiding rod 16, and the mounting member 131 may limit the displacement of the first guiding rod 16 along the axial direction.

Meanwhile, the softness of the accommodating cavity 11 can be improved, the extrusion force of the flat lens 20 is reduced, and the flat lens 20 is prevented from being damaged.

For example, the adjusting member 13 is a nylon member, and the mounting member 131 is a metal member. Therefore, the adjusting member 13 is made of nylon, has good wear resistance, toughness and lighter weight, reduces hard extrusion to the flat lens 20 when contacting with the flat lens 20, and avoids damage to the edge of the flat lens 20, and the mounting member 131 is made of metal, so that the connecting strength of the first guide rod 16, the first adjusting rod 15 and the adjusting member 13 can be increased.

Further, as shown in fig. 1, there are two first guide bars 16, and the two first guide bars 16 are respectively located at two sides of the first adjustment bar 15 and are symmetrically distributed about the second direction B.
