A pressure plate 11 is fixedly installed above the column 12, and a first cylinder 9 corresponding to the second cylinder 10 is fixedly installed at the lower right side of the pressure plate 11; a screw head groove 15 is opened inside the first cylinder 9; the first cylinder 9 is movably connected to the base plate 1 through the first connecting bearing 3, and the first cylinder 9 is rotated inside the base plate 1 through the first connecting bearing 3, and a spring 13 is installed on the outside of the limiting connecting column 12; the limiting connecting column 12 is a hexagonal column structure, and the shape and size of the limiting movable hole 16 are consistent with the shape and size of the limiting connecting column 12, and the limiting connecting column 12 is moved inside the limiting movable hole 16, and the pressure plate 11 is elastically connected to the base plate 1 through the spring 13; the worm 2 and the worm wheel 8 are rotated to drive the second cylinder 10 to rotate, and then the nut is driven to rotate through the nut groove 5, and then the nut is driven to rotate continuously, and at the same time, the screw head of the bolt is fixed to the column through the screw head groove 15 inside the first cylinder 9 to prevent the bolt from rotating. The two cooperate with each other to quickly complete the assembly of the nut and bolt, thereby improving the assembly efficiency of the nut and bolt.

[0024] Working principle: When using the nut and bolt assembly tool, first pull the pressure plate 11 upward, then release the pressure plate 11, and pull the pressure plate 11 downward under the elastic force of the spring 13. The first cylinder 9 and the second cylinder 10 clamp the bolt and the nut. The bolt head of the bolt is inside the screw head groove 15, and the nut is inside the nut groove 5. The screw part of the bolt is inserted into the inside of the through hole 4, wherein the shape and size of the bolt head are consistent with the shape and size of the inside of the screw head groove 15, and the shape and size of the nut are consistent with the shape and size of the inside of the nut groove 5. The diameter of the through hole 4 is slightly larger than the diameter of the screw part of the bolt, and then the handle 14 is turned to drive the operating worm. 2 rotates, and the worm gear 8 drives the second cylinder 10 to rotate, and then drives the nut to rotate. Secondly, the first cylinder 9 and the screw head groove 15 limit the rotation of the bolt, and the two cooperate with each other to assemble the nut and bolt together. Then, the spring 13 uses its own elastic force to apply a pulling force to the base plate 1 and the pressure plate 11 respectively. As the nut moves on the bolt, the limiting connecting column 12 moves inside the limiting movable hole 16, and adjusts the distance between the base plate 1 and the pressure plate 11 so that the screw head is always inside the screw head groove 15 and the nut is always inside the nut groove 5. Then, after the assembly is completed, pull the pressure plate 11 upward to remove the tool. This is the working principle of the nut and bolt assembly tool.
