Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Refer in Fig. 1-4, the utility model embodiment, a kind of PIN is driven spacing lens construction, including fixed cylinder 1
With revolving drum 2, the revolving drum 2 is enclosed in fixed cylinder 1, and the bottom of revolving drum 2 is provided with the work of three uniform annular array distributions
Screw 5 is installed in screw provided with three annular array distributions in dynamic groove, fixed cylinder 1, the screw, PIN4 is fixed on by screw 5
The periphery of fixed cylinder 1, the PIN4 is placed in the start groove of revolving drum 2, and screw 5 is fixed on by the nut 3 of the inner side of fixed cylinder 1
On safety barrel 1.
Above-mentioned, screw passes through PIN4 and screw.
It is above-mentioned, set three PIN4, three PIN4 to be generally aligned in the same plane in three screws
