The third stop 24 is respectively positioned opposite to the two hydraulic buffers 13. The hydraulic buffers 13 are used to contact the third stop 24 to achieve buffering before the limiting member 14 is pressed against the rotating plate 31.
[0039] Continue to refer to Figures 2-3 The first upright plate 42 is vertically connected to the top of the base plate 41, and the base plate 41 is placed flat on the rotating plate 31 and locked thereto. A set of first mounting grooves 411 are formed along the left and / or right sides of the base plate 41 in the front-back direction. A set of first locking holes are formed in the rotating plate 31. Locking screws pass through the first mounting grooves 411 and connect to the first locking holes. The position of the base plate 41 in the front-back direction, i.e., the front-back position, can be adjusted by adjusting the position of the locking screws in the first mounting grooves 411.
[0040] The camera is mounted on the support frame 51, which includes a horizontal plate, a second vertical plate, and a third vertical plate. The second vertical plate extends vertically downward from the right side of the horizontal plate, and the third vertical plate extends vertically upward from the left side of the horizontal plate.

A vertical groove is formed on the first vertical plate 42, extending through to the top of the first vertical plate 42. The second vertical plate is back-to-back with the first vertical plate 42. A second protrusion 52 is connected to the side of the second vertical plate facing the first vertical plate 42, and a first protrusion 43 is connected to the side of the first vertical plate 42 away from the second vertical plate near the blind end of the groove. The second protrusion slides into the groove from the top opening of the groove and is located directly above the first protrusion. The first protrusion 52 has a second mounting groove that runs vertically through it, and the second protrusion 52 has a second locking hole that runs vertically through it. The locking bolt 53 is locked with the second locking hole and also passes through the second mounting groove with a gap. The nut 54 of the locking bolt 53 rests on the first protrusion 43. The height of the second protrusion 52 relative to the first protrusion 43 is adjusted by adjusting the position of the nut on the locking bolt 53.
