In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "connected," and the like are to be construed broadly, and for example, "connected" may be either fixedly connected or detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1 to 4, the present invention provides an embodiment: the utility model provides a anchor clamps that aspherical mirror polishing was used, includes base 1, first ring 4, vacuum chuck 6 and second ring 8, and base 1 is fixed on the workstation, and the base 1 upper surface outside is annular array and is fixed with four pillars 2, and the top of four pillars 2 is fixed with the lower surface of first ring 4 respectively, and first ring 4 is located the top of base 1. The bottom of the inner side of the first circular ring 4 is fixedly connected with the outer side of the second circular ring 8, and the lower surface of the first circular ring 4 is aligned with the lower surface of the second circular ring 8. Four bolts 3 are installed on the first circular ring 4 in an annular array manner, four screw holes 9 matched with the bolts 3 are formed in the first circular ring 4 in an annular array manner, the bolts 3 penetrate through the screw holes 9, and a silica gel head 10 is fixed at one end, extending into the first circular ring 4, of each of the four bolts 3. The aspherical mirror is placed in the first ring 4, the second ring 8 supports the aspherical mirror, the four bolts 3 are respectively rotated, the silica gel heads 10 are abutted against the side face of the aspherical mirror, and the aspherical mirror is abutted and clamped through the four silica gel heads 10.
