Further, limiting blocks are respectively fixed on one side, far away from the end part of the precast beam, of the steel plate and on two sides of the locking through hole. The arrangement of the limiting block can ensure that the range of the included angle between the two ends of the steel cable and the precast beam is certain, and the excessive or the too small included angle can not ensure that the steel cable has enough vertical upward supporting force on the steel support, so that the aim of the device can not be achieved.
