The top of the support seat 509 is fixedly connected to a conical seat 511, and the conical seat 511 is adapted to some softer road surfaces, such as some dirt roads. The bottom end of the support seat 509 is fixedly connected to a universal wheel 510, and the universal wheel 510 can facilitate the overall movement. The bottom end of the support column 1 is fixedly connected to a circular plate 507, and the circular plate 507 plays a supporting role. The top of the circular plate 507 is rotatably connected to a connecting rod 506, and the connecting rod 506 can rotate. The inner wall of the bottom plate 2 is provided with an adjustment mechanism 6, and the adjustment mechanism 6 can adapt to shooting machines of different sizes.

[0034] Reference Figure 2The inner wall of the movable ring 502 is threadedly connected with a bolt 503, and a screw hole 508 is provided on the outer wall of the support column 1. The outer wall of the bolt 503 is threadedly connected to the inner wall of the screw hole 508, and the bolt 503 plays a limiting role, and there are three groups of screw holes 508, and the three groups of screw holes 508 correspond to the support seat 509, the universal wheel 510 and the conical seat 511.

The shape of the clamping block 505 is C-shaped, and the inner side wall length of the clamping block 505 is greater than the support seat 509, the inner side wall of the clamping block 505 is greater than the support seat 509, the universal wheel 510 and the conical seat 511, and is greater than the setting to avoid touching the clamping block 505 during rotation.

[0035] Reference Figure 3-Figure 5 The adjusting mechanism 6 includes a movable seat 601, the bottom end of the movable seat 601 is slidably connected to the inner wall of the bottom plate 2, and the adjustment purpose is achieved by sliding. The inner side wall of the movable seat 601 is rotatably connected with a rotating column 602, and the inner wall of the rotating column 602 is rotatably connected with a clamping seat 603. Through the movement of the movable seat 601, the rotating column 602 is driven to move, so that the clamping seat 603 moves toward the middle. The inner wall of the movable seat 601 is elastically connected with a latch 604 through a connecting spring 605. The latch 604 penetrates and is slidably connected to the inner wall of the movable seat 601. The penetrating setting is convenient for relevant personnel to move and operate. The bottom end of the clamping seat 603 is slidably connected to the inner wall of the bottom plate 2. The sliding movable seat 601 of the two can drive the clamping seat 603 to move.

[0036] Reference Figure 4-Figure 5 One end of the connecting spring 605 is fixedly connected to the outer wall of the pin 604, and the other end of the connecting spring 605 is fixedly connected to the inner wall of the movable seat 601. The outer wall of the pin 604 is slidably connected to the inner wall of the movable seat 601.

The outer wall of the movable seat 601 is fixedly connected with a handle 606, and the setting of the handle 606 facilitates the control of the movement of the movable seat 601.

[0037] Working principle: When the shooting location of the relevant personnel is changed, the support column 1 can be moved, and then the universal wheel 510 at the bottom will move, so as to facilitate movement. When it moves to the specified position, the bolt 503 can be rotated first to release the limit of the bolt 503 on the screw hole 508, and then the support column 1 is lifted up, and then the movable ring 502 is moved downward. At this time, the three groups of connecting rods 506 will rotate, thereby making the length of the telescopic rod 504 longer. When the length of the telescopic rod 504 is longer, the clamping block 505 will also move accordingly, thereby changing the angle of the universal wheel 510, so that the ground of the support seat 509 faces downward, thereby adapting to some cement or tile roads, making shooting more stable. At this time, the bolt 503 corresponds to the middle screw hole 508. When the movable ring 502 continues to be moved downward, the bolt 503 corresponds to the bottom screw hole 508, so that the conical seat 511 faces downward, thereby adapting to relatively soft dirt roads, and the operation is simple and convenient.

[0038] When the camera on the top plate 4 needs to be replaced, the movable seat 601 is directly moved through the handle 606. When the movable seat 601 moves, it will drive the two groups of rotating columns 602 to move, and then the two groups of clamping seats 603 will also move toward the middle, so as to clamp and fix the camera. The operation is simple and convenient. When the movable seat 601 moves, it will drive the latch 604 to move, and then the latch 604 will also move upward due to being squeezed. When the two groups of clamping seats 603 clamp the camera, the elasticity of the connecting spring 605 resets the latch 604 to complete the fixing operation. The movement of the movable seat 601 can adapt to machines of different sizes. The operation is simple and convenient.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
