[0015] The beneficial effects of this invention are:

[0016] 1. In this invention, by setting a limit component, the electric push rod is opened, and the output shaft of the electric push rod pushes the push plate to move. The push plate drives the base plate to move, and the base plate moves via the mounting plate. The mounting plate drives the first transmission column to move, and the first transmission column drives the first threaded rod to move. The first threaded rod drives the gear to move, and the gear rotates via a toothed rack. The gear drives the first threaded rod to rotate, and simultaneously, the first threaded rod drives the first transmission column to rotate. The first bevel gear on the first transmission column meshes with the second bevel gear on the power rod, causing it to drive the power rod to rotate. The power rod, through the second bevel gear at its other end and the first bevel gear on the second transmission column, drives the second transmission column to rotate. The second transmission column drives the second threaded rod to rotate. The outer walls of the first and second threaded rods are connected to the connecting ring. The device is connected by threads. The connecting ring drives the connecting rod to move, and the connecting rod drives the first connecting block to move on the top surface of the first fixed plate. At the same time, the connecting rod moves on the inner wall of the first stroke groove set on the top surface of the first fixed plate. The first connecting block drives the first clamping plate to move. Simultaneously, the first connecting block drives the second connecting block to move on the top surface of the second fixed plate through the connecting long plate. The connecting long plate moves on the inner wall of the second stroke groove set on the top surface of the second fixed plate. The movement of the second connecting block drives the movement of the second clamping plate, thus clamping the packaged electric porcelain insulator. This design effectively fixes the electric porcelain insulator inside the device, thereby preventing the electric porcelain insulator from shaking inside the storage and transportation device during transportation and preventing damage caused by collisions between the electric porcelain insulators. It has a good performance.

[0017] 2. In this invention, by providing a pushing component, the output shaft of the electric push rod drives the base plate to move through the pushing plate. At the same time, the third slider on the base plate moves on the inner wall of the third slide groove. Simultaneously, the base plate drives the first and second transmission columns to move through the mounting plate. The movement of the first and second transmission columns simultaneously drives the movement of the first and second threaded rods. The movement of the first and second threaded rods simultaneously drives the overall limiting component to move, pushing it to the outside of the outer shell. Through this design, the internal mechanism of the device is effectively displayed, allowing the staff sufficient space to place the power insulators, thereby greatly reducing the error rate during operation and achieving good results.

[0018] 3. In this invention, by providing a shock-absorbing component, when the storage and transportation device is subjected to external impact force, the shock-absorbing plate in the shock-absorbing component moves inward into the outer shell, and the limiting plate on the shock-absorbing plate moves within the inner shell. At the same time, the shock-absorbing plate compresses the first shock-absorbing spring, and the first shock-absorbing telescopic rod retracts. During this process, the external impact force is buffered, thereby reducing the external impact force. The second shock-absorbing telescopic rod works on the same principle as the second shock-absorbing spring, buffering the impact force received by the back of the outer shell. Through this design, shock absorption of the internal components of the storage and transportation device is effectively achieved, which can effectively prevent the storage and transportation device from being damaged by external impact force, resulting in good performance.
