[0035] Reference Figure 1-Figure 4 The support assembly includes: a slide rail 501 and a sliding cylinder 505. The slide rail 501 is fixedly connected to the upper left end of the electric lifting rod 2. A moving rod 502 is slidably connected below the slide rail 501. The moving rod 502 can slide left and right under the limit of the slide rail 501. The bottom end of the moving rod 502 is fixedly connected to a limiting block 503. When the limiting block 503 moves, it can drive the moving rod 502 to move synchronously. The limiting block 503 is arranged in a rectangular block structure. A screw hole 504 is opened on the bottom surface of the limiting block 503. The sliding cylinder 505 is arranged below the moving rod 502. The limiting block 503 is sleeved inside the sliding cylinder 505. The left end of the rod 502 passes through the sliding cylinder 505, and the limit block 503 can limit the moving rod 502, so that the bottom end of the moving rod 502 cannot escape from the interior of the sliding cylinder 505, and at the same time, the moving rod 502 can only move linearly relative to the sliding cylinder 505 but cannot rotate. The inner bottom surface of the sliding cylinder 505 is rotatably connected with a screw 506, and the screw hole 504 passes through the moving rod 502. The screw 506 is threadedly connected to the inner surface of the screw hole 504. When the screw 506 rotates, it can drive the moving rod 502 to move synchronously, so that the moving rod 502 moves linearly relative to the sliding cylinder 505 when the screw 506 rotates.

[0036] The outer side of the screw rod 506 is fixedly connected with a driven sprocket 507. When the driven sprocket 507 rotates, the screw rod 506 can be driven to move synchronously. A through groove 508 is provided on the bottom surface of the sliding cylinder 505. A driving assembly is arranged at the bottom end of the sliding cylinder 505. The driving assembly includes a fixed plate 701. The fixed plate 701 is fixedly connected to the bottom surface of the sliding cylinder 505. The left surface of the fixed plate 701 is rotatably connected with a driving sprocket 702. The left end of the driving sprocket 702 is fixedly connected with a crank 703. The driving sprocket 702 is driven by a chain 704. It is connected to the driven sprocket 507 by transmission. When the staff rotates the crank 703, the driving sprocket 702 can be driven to rotate. At this time, the rotation of the driving sprocket 702 can drive the driven sprocket 507 to rotate through the chain 704. At this time, the synchronous rotation of the screw 506 can drive the moving rod 502 to move. A supporting groove 509 is provided on the left side surface of the electric lifting rod 2. The right end of the sliding cylinder 505 is slidably connected to the inside of the supporting groove 509. The sliding cylinder 505 can perform a linear motion in the up and down directions inside the supporting groove 509.

[0037] The movable rod 502 and the sliding cylinder 505 are arranged to form a stable triangular support structure at the bottom end of the camera 4, so that the camera 4 can remain stable during long-term use, and avoid shaking of the camera 4 during use due to the longer extension of the telescopic arm 3. When the electric lifting rod 2 is started to move the camera 4 upward, the support assembly will move synchronously with the camera 4, and a right-angled triangle structure is formed at the bottom ends of the camera 4 and the telescopic arm 3 to support the camera 4. When the telescopic arm 3 is shortened or extended to drive the camera 4 to move horizontally, the staff can rotate the crank 703 to drive the movable rod 502 to extend or shorten relative to the sliding cylinder 505, so that the support assembly can still maintain a stable supporting effect at the bottom end of the camera 4, so that the camera 4 remains stable during use, and avoids shaking or downward deviation caused by gravity.

[0038] Reference Figure 1-Figure 5, both front and rear ends of the sliding cylinder 505 are provided with limiting rods 601, the bottom ends of the limiting rod 601 and the supporting inclined plate 603 are fixedly connected to the upper surface of the movable base 1, the outer wall of the limiting rod 601 fits with the outer wall of the sliding cylinder 505, and the movement of the sliding cylinder 505 can be guided and limited to avoid the sliding cylinder 505 from being offset in the front and rear directions and being unable to be adjusted, and a limiting groove 602 is provided on the side surface of the limiting rod 601 close to the sliding cylinder 505, and a supporting inclined plate 603 is fixedly connected to the side surface of the limiting rod 601 away from the sliding cylinder 505, and the sliding cylinder can be guided and limited by the cooperation of the supporting inclined plate 603 and the limiting rod 601 The outer side of 505 is protected to reduce the displacement of the sliding cylinder 505 due to impact. The two limit rods 601 at the front and rear ends of the sliding cylinder 505 are fixedly connected by a connecting rod 604. The connecting rod 604 makes the two limit rods 601 form a whole, further improving the stability. The front and rear surfaces of the sliding cylinder 505 are fixedly connected with sliders 605. The sliding cylinder 505 is connected to the internal sliding of the limiting slide groove 602 through the slider 605. Through the cooperation of the set slider 605 and the limiting slide groove 602, the movement of the sliding cylinder 505 can be further guided and limited to avoid the displacement of the sliding cylinder 505 in the up and down directions.

[0039] Working principle: the movable rod 502 and the sliding cylinder 505 can form a right-angled triangle stable support structure at the bottom of the camera 4 and the telescopic arm 3. When the electric lifting rod 2 is started to drive the camera 4 to move in a straight line in the up and down directions, the support assembly follows the movement to keep the support for the camera 4 stable. When the telescopic arm 3 drives the camera 4 to move in the left and right directions, the staff can rotate the crank 703 to drive the movable rod 502 to extend or shorten relative to the sliding cylinder 505, so that the support assembly can still maintain a stable support effect at the bottom of the camera 4. The limit rod 601, slider 605 and limit slot 602 can guide and limit the movement of the sliding cylinder 505, so that the sliding cylinder 505 remains stable during movement to avoid deviation.
