The bottom end of the drawer 8 is slidably connected to the inner side of the box body 1. A plurality of chambers 10 are provided inside the front side of the box body 1 to provide additional accommodating space. The inner sliding connection of the chamber 10 is connected to a limit plate 11 to provide a limit. The front side of the limit plate 11 is fixedly connected to a push block 12, and the bottom end of the limit plate 11 is fixedly connected to a push block 12. The limiting rod 13 is used to limit the limiting rod 13. The outer sleeve of the limiting rod 13 is provided with a strong spring 14 to provide necessary elastic force.

[0027] Working principle: When lubricating, the operator first uses a suitable tool to tighten the bolt 4, which will cause the fixing plate 3 to loosen, thereby opening the entrance of the track groove 5. Subsequently, the operator will apply lubricating oil to the track groove 5 to ensure that the pulley 6 and the T-shaped slider 7 are properly lubricated, so that when the drawer 8 is pulled, the T-shaped slider 7 can move smoothly along the track groove 5 with the help of the pulley 6, avoiding damage caused by jamming and friction. Then, when pulling the drawer 8, first press the push block 12 to move the push block 12 inside the push hole 18, and then drive the limit plate 11 to move inside the chamber 10. The movement of the limit plate 11 will cause the limit rod 13 to slide inside the limit hole 17, so that the strong spring 14 is stressed, and the movement of the limit plate 11 will also cause the engagement The connecting rod 15 drives the baffle 16 to move, and then pulls the drawer 8 to drive the blocking hole 9 to move, so that the baffle 16 blocks it, and the strong spring 14 will also generate a rebound force due to the force. This force will be used to help the subsequent drawer 8 to be locked in a fixed position. During the installation of the wires, when the wires are clamped on the adjacent sides of multiple arc-shaped clamping blocks 25, these arc-shaped clamping blocks 25 will be subjected to pressure, and this pressure will be transmitted to the sliding rod 21, thereby causing the limit plate 22 to move in the circular hole 23, and at the same time causing the strong spring 24 to be compressed. The rebound force of the strong spring 24 will provide a continuous clamping force to ensure that the wires are firmly fixed in place.
