[0023] See also Figure 4In this embodiment, the rotating assembly 2 includes an outer disk 201, an inner disk 202, a first positioning hole 203, a second positioning hole 204 and a positioning plug 205; the inner side of the outer disk 201 is slidably connected to the inner disk 202; a limiting mechanism is set between the outer disk 201 and the inner disk 202; when the vise body 3 rotates, it drives the inner disk 202 to rotate inside the outer disk 201. After the workpiece angle to be adjusted is reached, the positioning plug 205 is sequentially inserted into the first positioning hole 203 and the second positioning hole 204 for positioning. The outer side of the outer disk 201 is provided with a first positioning hole 203 distributed in an annular manner at equal distances; the outer side of the inner disk 202 is provided with a second positioning hole 204 distributed in an annular manner at equal distances; the first positioning hole 203 and the second positioning hole 204 have the same number of circular holes and the same aperture; the first positioning hole 203 and the second positioning hole 204 have the same number of circular holes and the same aperture; A positioning rod 205 is inserted between the positioning hole 203 and the second positioning hole 204; this design allows the bench vise and the clamped workpiece to rotate 360 degrees, so that the workpiece can be rotated and positioned in any direction, improving the flexibility and convenience of workpiece operation. The mounting assembly 5 includes a mounting hole 501, a clamping frame 502, a positioning threaded sleeve 503, a fixing bolt 504, an adjustment structure 505 and abutment plate 506; a positioning threaded sleeve 503 is engaged and connected to the inner side of the mounting hole 501; the mounting hole 501 and the positioning threaded sleeve 503 are installed and connected by a fixing bolt 504; the mounting assembly 5 can be added according to the use environment of the bench vise. During assembly, the positioning threaded sleeve 503 of the clamping frame 502 is inserted from the lower end into the mounting hole 501 opened in the base 1.
