Problems solved by technology

However, the locking device usually bears a large pressure during the working process. During the long-term opening and closing process, the opening and closing locking device is prone to friction and wear, which reduces the locking pressure and loses the pressure balance.
At the same time, during the opening and closing process, the friction will generate high surface temperature, which will easily cause surface friction cracking of the opening and closing locker, reduce the use efficiency, and shorten the service life (Quan Bing, reliability analysis of packer locking device based on finite element method, Neijiang Science and Technology, Issue 3, 2018)
