The bracket 17 set, the bottom side of the wall of bracket 17 are rotatably connected to wheel 18, and when pushing pedestal 1, wheel 18 can drive bottom
Seat 1 is mobile, eliminates the trouble of manual handling, saves physical strength, when wheel 18 encounters the road surface jolted and vertical tremor, bullet
The elastic force of spring 16 can slacken the vibration of wheel 18, guarantee that pedestal 1 more stably moves, protect part inside projector 4 not by
The damage of vibration；
The upper surface of pedestal 1 is equipped with the first column 2 vertically, and the first column 2 is equipped with the second sliding chamber close to the side wall of bull stick 8
21, and slide bar 22 is slidably connected in the second sliding chamber 21, the bottom side of the wall of slide bar 22 is equipped with positioning pin 23 vertically, and bull stick 8
Side wall, which is offered, to be freely fallen on bull stick 8 with the matched location hole 24 of positioning pin 23, positioning pin 23 by the effect of self gravity
Location hole 24 in, such bull stick 8 just no longer rotates, and realizes the fixation to bull stick 8；
First column 2 is hollow structure, is equipped with the second column 3 in the first column 2 vertically, and the second column 3 runs through first
The upper end side wall of column 2 is arranged, and the second column 3 is equipped with projector 4 far from one end of the first column 2, in the two sides of the first column 2
Wall is equipped with the first sliding chamber 5, and the two sides side wall of the second column 3 passes through the first slide bar 6 and is slidably connected with the first sliding chamber 5, by
It is slidably connected in the second column 3 by the first slide bar 6 and the first sliding chamber 5, therefore the axial rotation of the second column 3 is limited, again
Because nut 13 is fixedly connected by connecting rod 14 with the inner wall of the second column 3, the axial rotation of nut 13 is also limited；
The side inner wall of first column 2 is rotatably connected to the bull stick 8 being laterally arranged by the first rotating member 7, is located at first
8 one end of bull stick in 2 outside of column is equipped with handle 25, and handle 25 can facilitate rotation bull stick 8, and sponge protection is enclosed on handle 25
Set, sponge protective case can protect hand not to be scratched, and bull stick 8 runs through the side of the first column 2 far from one end of the first rotating member 7
Wall setting, the sidewall sheath of bull stick 8 are equipped with the first helical gear 9, and the lower end inner wall of the first column 2 is connected by the rotation of the second rotating member 10
It is connected to the threaded rod 11 being vertically arranged, the upper end of threaded rod 11 is equipped with block 26, and the diameter of block 26 is greater than the straight of nut 13
Diameter, block 26 can prevent nut 13 from removing threaded rod 11, and the sidewall sheath of threaded rod 11 is equipped with matched with the first helical gear 9
Second helical gear 12, the second helical gear 12 can be meshed with the first helical gear 9, and the second column 3 is hollow structure, threaded rod 11
