Detailed Description
As shown in figures 1 to 7, a manual fastening nut adopts a brand-new structural design, is mainly installed and matched in a handheld fastening mode when in use, is assembled and connected in an upper end and a lower end through two fastening modes respectively, is higher in overall efficiency during installation, is more convenient to operate, can meet the assembly requirement of a quick connection combination, is easier to disassemble and assemble during later maintenance, and is higher in use flexibility. It includes that the center pin is cylindrical main part fastening spliced pole 1 of upper and lower direction, be equipped with handheld fastening on the outer face of cylinder of main part fastening spliced pole 1 and stabilize antiskid groove 2, the upper end central point of main part fastening spliced pole 1 puts and is equipped with cylindrical first main part installation fastening hole 3, and it can be in the same place with the upper end structure locking-up. And an assembling and connecting thread groove is formed in the inner cylindrical surface of the first main body mounting and fastening hole 3, and can be in threaded fit connection. The lower end center position of the first main body mounting and fastening hole 3 is provided with a cylindrical center matching through hole 4 penetrating through the lower end face of the part, so that the upper structure and the lower structure are in a communicated state, and the mounting requirements of various connecting structures can be met when the connecting structure is used. The center of the lower end of the main body fastening connecting column 1 is provided with a cylindrical second main body mounting fastening hole 5 which can be connected with the lower end structure in a quick matching manner. The inner cylindrical surface of the second body mounting and fastening hole 5 is provided with circular arc-shaped second fastening anti-loose clamping columns 6 which are uniformly distributed on the circumference close to the lower end, and clamping and fastening are carried out through the circular arc-shaped second fastening anti-loose clamping columns when assembling is carried out. The lower end edge position of the second fastening anti-loose clamping column 6 is provided with an installation matching guide arc 7, so that the installation smoothness during matching is better, the lower end structure is firstly upwards inserted into the second main body installation fastening hole 5 from the position during assembling, and then the clamping anti-loose assembly is realized through rotation.
Preferably, the handheld fastening stable anti-skid groove 2 is composed of diamond structures which are uniformly and alternately distributed, so that the anti-skid effect is better when the handheld fastening stable anti-skid groove is used, and the handheld comfort is better when the handheld fastening stable anti-skid groove is fastened.
