[0020] like Figure 1-4As shown, the utility model proposes a hardware fastening device for hardware processing, including a fixed base 1 and a splint 3, a pair of driving arms 2 are slidably connected to the upper end of the fixed base 1, and a driving component for driving the driving arm 2 to move is arranged in the fixed base 1, a mounting block 21 is fixed to the side close to the upper end of the driving arm 2, a mounting plate 31 is fixed to the back plate of the splint 3, the size of the mounting plate 31 is adapted to the size of the mounting block 21, and a disassembly and assembly component 4 is arranged at the connection between the two, a limiting rod 14 is fixed to the upper end of the fixed base 1, the limiting rod 14 passes through the driving arm 2 and is slidably connected to the driving arm 2, and an anti-slip protection pad is fixed to the side close to the splint 3.

[0021] The driving assembly includes a driving groove 11 and a rocker 15. The driving groove 11 is opened in the fixed base 1. A pair of threaded sleeves 12 are slidably connected in the driving groove 11. The bottom of the driving arm 2 is fixed to the upper end of the threaded sleeve 12. The rocker 15 is rotatably connected to the outer wall of the fixed base 1 and is aligned with the driving groove 11. A bidirectional screw 13 is rotatably connected in the driving groove 11. The bidirectional screw 13 passes through the threaded sleeve 12 and is threadedly connected to the threaded sleeve 12. The end of the bidirectional screw 13 is fixed on the rocker 15.

[0022] The disassembly and assembly component 4 includes a rotating plate 41 and a circular groove 42. The rotating plate 41 is fixed at the center position of the back side of the mounting plate 31 by a connecting rod. The circular groove 42 is opened in the mounting block 21. An elliptical opening 43 is opened at the center position of the outer side of the circular groove 42. A positioning hole 44 is opened at one corner of the mounting plate 31. A positioning block 45 is installed on the mounting block 21 at a position corresponding to the positioning hole 44. A telescopic groove 46 is opened on the mounting block 21 at a position corresponding to the positioning block 45. A telescopic spring 47 is fixed between the positioning block 45 and the inner side wall of the telescopic groove 46.
