The screw and nut disassembly and assembly tool of Yueluo also includes a rotating rod, a sleeve and a fixed rod fixedly connected to the sleeve rod at one end, and the other end of the fixed rod is connected with one end of the rotating rod to make the rotation The rod can be rotated around the connection point, and the sleeve for accommodating nuts or screws is fixedly connected with the other end of the rotating rod; rotating the rotating rod makes the sleeve head and the opening of the sleeve opposite , by keeping the nut or screw in the sleeve fixed while the corresponding screw or nut in the sleeve head rotates, so as to achieve simultaneous force and disassembly of the screw and the nut.
Alloy Steel Nuts Hexagon Nuts (GB6170/DIN934, GB6175), Flange Nuts (GB6177/DIN6923) Round Nuts (GB812), Small Round Nuts (GB810), American Square Nuts, American Hex Nuts (ANSI/ASME B18.2.2) , Heavy-duty nuts (metric, US). Size: 5/16-4.
When using, after installing the nut and the bolt in place, insert the locking strip from the groove of the bolt, and make the V-shaped locking teeth of the locking strip snap into one of the V-shaped tooth grooves, and push the locking strip into the groove as a whole. The V-shaped locking teeth are stuck in the nut, and the locking strip body is stuck in the groove of the bolt, thereby restricting the relative rotation of the nut and the bolt, and there are threads between the nut and the bolt to restrict their relative sliding, so it can prevent the nut from loosening, even from The bolt falls off; when the nut needs to be disassembled, it is only necessary to pull out the locking strip from the groove, and the nut can be disassembled normally.
The connecting fasteners of the existing panel furniture are generally composed of pins, screws and nuts. When connecting two furniture boards, a nut must be placed in the hole first, then the screw is tightened, and then the pin is connected, which is not very convenient to assemble. Wood screws are generally used for fixing the existing concealed hinges, and the positioning is inaccurate, the installation is laborious and time-consuming, the labor intensity is high, and the work efficiency is low.
