[0034] like Figure 1 The ophthalmic lens assembly support of one embodiment of the present invention is shown, which comprises a grip portion 1 and a lens assembly ring 2 rotatably connected to the grip portion 1. The lens assembly ring 2 is provided with a receiving cavity 23, and the receiving cavity 23 is as follows Figure 6 The hollow structure shown; the accommodating cavity 23 is used to place the goniometer lens 3; wherein the goniometer lens 3 can also be other ophthalmic lens sets, such as triangular lens sets.

[0035] like Figure 2 As shown, in this embodiment, the holding portion 1 includes a main body and clamping ends 12 arranged on both sides of the main body, and the main body is provided with a receiving clamping ring 111; wherein the holding portion 1 is a rigid structure. An annular groove 21 is provided on the circumferential outer side of the lens assembly ring 2, and the lens assembly ring 2 is rotatably engaged with the receiving clamping ring 111 through the annular groove 21, that is, the receiving clamping ring 111 can be engaged with the annular groove 21, and the receiving clamping ring 111 can rotate along the track defined by the annular groove 21. At least one side of the annular groove 21 is provided with a circumferentially distributed dial ring 22, which can be moved by a finger to drive the lens assembly ring 2 to rotate relative to the receiving clamping ring 111. Obviously, the dial ring 22 can also be driven by other conventional forms. The annular groove in this embodiment is as shown in FIG. Figure 7 As shown, both upper and lower sides of the annular groove 21 are provided with circumferentially distributed shifting rings 22, or only the upper side or only the lower side has the shifting ring 22, and the shifting ring 22 is evenly distributed with protrusions to increase the friction when shifting.

[0036] like Figure 3 As shown, in this embodiment, the clamping end 12 is connected by a connecting handle 13 and a receiving clamp ring 111, and the clamping end 12 has an arc-shaped end face, which is a minor arc shape. The advantage is that when two fingers clamp the clamping end 12 on both sides of the main body, the two fingers can be in a major arc shape, thereby being able to clamp the clamping end 12 on both sides of the main body more stably.

[0037] The clamping end 12 is symmetrically arranged on the left and right sides of the main body, and the arc-shaped end surfaces are symmetrically distributed up and down at the end of the connecting handle 13, which has the advantage of conveniently switching the clamping of the clamping end 12 by the left and right hands.
