[0031] The second connecting portion 22 is provided with a second inclined surface 221, and the second inclined surface 221 is arranged parallel to the first inclined surface 121. When the fixing member 10 is connected to the pressing member 20, the first inclined surface 121 is in contact with the second inclined surface 221.

[0032] A matching portion 222 is disposed on the second inclined surface 221 , and the matching portion 222 matches the sliding portion 122 .

[0033] In this embodiment, the fixing member 10 and the clamping member 20 are connected by the first bolt 40. When the fixing member 10 and the clamping member 20 are connected by the first bolt 40, the first bolt 40 can drive the matching portion 222 to slide along the sliding portion 122, so that the supporting portion 21 presses against the workpiece 60.

[0034] Specifically, a first threaded hole 123 is provided on the sliding portion 122, and a first through hole 223 is provided on the second connecting portion 22. When the clamping member 20 is connected to the fixing member 10 via the first bolt 40, the first bolt 40 passes through the first through hole 223 and is threadedly connected to the first threaded hole 123, which facilitates assembly and disassembly.

[0035] In this embodiment, the sliding portion 122 is a protrusion, and the matching portion 222 is a groove. The protrusion is accommodated in the groove, and there is a clearance fit between the protrusion and the groove, and the protrusion and the groove are slidably connected.
