turn through the different driving force of the two groups of handles 4, then when the present application needs to collect the prefabricated part 43, first, the relative distance between the shaft bushing 19 and the driving block 20 can be adjusted by rotating the first crank 22, the first crank 22 drives the screw rod 21 to rotate through the shaft bushing 19, the screw rod 21 drives the driving block 20 to move along the screw rod 21 through the threaded connection with the driving block 20, so as to adjust the relative distance between the shaft bushing 19 and the driving block 20,

friction surface of the tooth back of the ratchet wheel 31 and the pawl 37 is in contact with each other, at this time, the ratchet wheel 31 drives the pawl 37 to press down, and the first spring 36 is compressed, when the ratchet wheel 31 rotates over a group of ratchet teeth, the pawl 37 is automatically lifted under the drive of the first spring 36, so as to be inserted into the tooth groove, and then the ratchet wheel 31 is one-way limited, the ratchet wheel 31 limits the driving shaft 26, so that the winding drum 27 can only wind the steel cable 28 but cannot release it, the steel cable 28 pulls up the prefabricated part 43, and in the process of rising, the prefabricated part 43 drives the right angle rotating frame 9 to rotate, so as to rotate and store the right angle rotating frame 9 into the mounting groove 6, and in the process, the right angle rotating frame 9 compresses the tab spring 10, then when the prefabricated part 43 passes the right angle rotating frame 9, the right angle rotating frame 9 loses the limit, at this time, the right angle rotating frame 9 rotates and pops out from the mounting groove 6 under the push of the tab spring 10, then the pull ring 42 can be pulled, the pull ring 42 drives the telescopic rod 39 to stretch and retract, the telescopic rod 39 drives the sliding block 33 to slide in the sliding groove 32, at the same time, the telescopic rod 39 compresses the second spring 41 through the stop block 40, at the same time, the sliding block 33 drives the lifting plate 35 to slide through the fixed rod 34, the lifting plate 35 drives the pawl 37 to separate from the ratchet wheel 31,Thus, the one-way limit of the driving shaft 26 is removed, and the second handle 30 is shaken in reverse direction, so as to release the steel cable 28, and then the prefabricated part 43 is lowered, and the prefabricated part 43 falls into the right-angle rotating frame 9, so as to be lifted by the right-angle rotating frame 9, in the process, the bottom of the right-angle rotating frame 9 is first limited by the cooperation of the bracket 8 and the right-angle rotating frame 9, so that the bottom of the right-angle rotating frame 9 remains horizontal, thereby lifting the prefabricated part 43, and due to the downward pressure of the prefabricated part 43, the right-angle rotating frame 9 is overturned downward, thereby driving the other side of the right-angle rotating frame 9 to fold towards the prefabricated part 43, and then through the cooperation of the two groups of right-angle rotating frames 9, the prefabricated part 43 is lifted and clamped on both sides at the same time, so as to prevent the prefabricated part 43 from shaking and falling during movement, and then when the prefabricated part 43 needs to be released, the prefabricated part 43 also needs to be pulled and fixed by the steel cable 28 and the safety hook 29, and the prefabricated part 43 is lifted, in the process, the prefabricated part 43 loses the lifting and clamping of the right-angle rotating frame 9, and then the pull handle 48 is pulled to rotate the fixed shaft 7, the fixed shaft 7 drives the right-angle rotating frame 9 to rotate and be stored in the mounting groove 6, then the pull ring 42 is pulled out to drive the ratchet 37 to disengage the ratchet 31, and then the second handle 30 is shaken in reverse direction to control the release of the steel cable 28, so as to drive the prefabricated part 43 to fall and be released, so as to realize the transfer and storage of the prefabricated part 43.
