[0002] With the continuous development of industry, more and more companies use special handling mechanisms to transport materials to different workstations during the production process to meet the needs of various processing procedures. Among them, some materials need to be stored and transported through jigs. However, during the use of jigs, debris will inevitably remain on the jigs, and the remaining debris needs to be removed when it is used again.

[0003] For some jigs including a base plate and a cover plate, the jig in an open state is usually turned over first, and the front and back sides of the base plate and the cover plate of the jig are blown with the help of a blowing device to remove residual debris on the jig; during the jig turning process, the jig needs to be fixed to prevent it from falling during the turning process. Most existing fixing methods separately set up two sets of fixing components to fix the cover plate and the base plate of the jig respectively, which has the disadvantages of complex structure and high cost.
