[0053] An adjustment method for the active adjustment component of a projector is specifically as follows:

[0054] When installing the projector body 1 outdoors, find a suitable tree trunk or vertical rod. In the technical solution of the present invention, the tree trunk can be selected locally in the wild, the vertical rod can be a portable accessory, or a building, and can also be an element inserted into the ground at will.

[0055] The first semi-ring mounting bracket 2 is fixed to the periphery of the tree trunk or vertical rod by inserting the fixed ground rod 21 into the ground. Then, the insertion connecting block 38 is inserted into the insertion connecting cavity 25 to realize the connection between the first semi-ring mounting bracket 2 and the second semi-ring mounting bracket 3. At this time, the alignment lock holes 39 are aligned with the locking through holes 26, and at the same time, the protruding connecting block 52 is also inserted into the matching insertion cavity 81. Then, the projector body 1 is inserted into the installation sleeve 35, and the fixing connection holes 11 are aligned with the matching lock holes 36. At this time, the threaded driving column 6 can be rotated to move downward under the action of the thread. It will drive the driving ring plate 8 to move downward. Under the action of the driving ring plate 8, the movable ring plate 5 will be driven to move downward. In this way, under the action of the first connecting hinge rod 57, the threaded sleeve 4 on the first semi-ring mounting bracket 2 will be pulled towards the tree trunk or vertical rod. At the same time, as the installation ring sleeve 7 moves downward, under the action of the second connecting hinge rod 77, the threaded sleeve 4 on the second semi-ring mounting bracket 3 will be pushed towards the tree trunk or vertical rod.

[0056] The cooperating arc plate 45 is moved towards the tree trunk or the vertical rod, so that the cooperating arc plates 45 in multiple directions can be attached to the tree trunk or the vertical rod. When a certain cooperating arc plate 45 cannot be attached to the tree trunk or the vertical rod, the threaded adjusting rod 43 can be rotated at this time. Under the action of the thread, the movement of the threaded adjusting rod 43 is realized, and then the cooperating arc plate 45 is driven to move for fine adjustment to achieve attachment to the tree trunk or the vertical rod. In addition, as the driving ring plate 8 moves downward, the plugging lock rod 84 will also be sequentially plugged into the locking through hole 26 and the alignment lock hole 39 to realize the fixed connection between the first half-ring mounting bracket 2 and the second half-ring mounting bracket 3. In this way, with the support of multiple cooperating arc plates 45 and relying on the tree trunk or the vertical rod, the firm installation of the first half-ring mounting bracket 2 and the second half-ring mounting bracket 3 can be fully ensured, and the phenomenon of tipping will not occur. In addition, during the downward movement of the mounting ring sleeve 7, under the action of the inclined parallel double plates 73, the movable lock frame 74 will be driven to move towards the mounting bearing sleeve 35, so that the movable lock post 76 is plugged into the fixed connection hole 11 to realize the fixation of the projector body 1. That is, the fixation of the projector body 1 can be realized while installing the first half-ring mounting bracket 2 and the second half-ring mounting bracket 3. The operation is simple, convenient and fast, which can ensure the firm installation of the projector body 1, and thus ensure the safe use of the projector body 1. During disassembly, only the threaded driving column 6 needs to be rotated in the reverse direction.
