[0013] As Figures 1 to 6 shown, the special marine lens alignment device of the present utility model includes a vehicle body 1, and a support body 9 is provided above the vehicle body 1.
[0014] One end of the vehicle body 1 is vertically and fixedly connected with a fixed sleeve 4, a first lead screw 6 is inserted into the fixed sleeve 4, there is a gap between the first lead screw 6 and the inner hole of the fixed sleeve 4, and a first nut 5 with a first handle 17 that mates with the first lead screw 6 is located on the upper end surface of the fixed sleeve 4. One end of the support body 9 is fixedly provided with a first connecting ear 8 below, and the upper end of the first lead screw 6 is rotationally connected with the first connecting ear 8 through a first pin shaft 7, and the axis of the first pin shaft 7 is perpendicular to the longitudinal direction of the vehicle body 1.
[0015] At the other end of the vehicle body 1, there is a support slide plate 18. There is an oblong hole 21 on the support slide plate 18. The swing sleeve 15 is inserted into the oblong hole 21, and support screws 19 are threadedly connected to both sides of the support slide plate 18. The inner end heads of the support screws 19 are inserted into the holes on the swing sleeve 15, ensuring that the swing sleeve 15 can swing relative to the support slide plate 18 within the oblong hole 21 with the support screws 19 as the axis. The second lead screw 12 is inserted into the swing sleeve 15, and there is a gap between the second lead screw 12 and the inner hole of the swing sleeve 15. The second nut 13 that mates with the second lead screw 12 and is provided with a second handle 14 is located on the upper end face of the swing sleeve 15. At the lower part of the other end of the support body 9, a second connecting ear 10 is fixed. The upper end of the second lead screw 12 is rotatably connected to the second connecting ear 10 through a second pin shaft 11, and the axis line of the second pin shaft 11 is perpendicular to the longitudinal direction of the vehicle body 1.
[0016] The support slide plate 18 is threadedly connected to the lead screw 20. The lead screw 20 is perpendicular to the longitudinal direction of the vehicle body 1. Both ends of the lead screw 20 are supported on both sides of the vehicle body 1 through bearings and axially limited. A handwheel 3 is installed at the end of the lead screw 20.
[0017] The upper surface of the support body 9 is in a groove shape and support members 16 are distributed on both sides. The support members 16 can be selected as heavy-duty universal nylon balls.
