[0007] According to the above technical solution, the limit rod slides through the left and right walls of the receiving shaft, and the end of the limit block close to the toggle plate is set as a bevel surface 1, which facilitates the resetting of the H-shaped support rod.

[0008] According to the above technical solution, a No. 1 spring is arranged between the toggle plate and the receiving shaft. Under the action of the No. 1 spring, the toggle plate will drive the limit rod to contact the slot and fix the H-shaped support rod. A No. 2 spring is arranged between the H-shaped support rod and the U-shaped rod. The No. 2 spring can maintain the stability of the drone during the lifting process.

[0009] According to the above technical scheme, the stabilizing device also includes an H-shaped plate, a receiving rod and a roller. When the H-shaped support rod is impacted, the H-shaped support rod moves toward the direction close to the U-shaped rod to squeeze the No. 2 spring to contract. The H-shaped plate is rotatably installed on the end of the connecting rod away from the receiving block. The receiving rod is fixedly penetrated through the inner and outer walls of the H-shaped plate. The roller is rotatably installed on the circumferential surface of the receiving rod. A sliding groove is provided on the surface of the U-shaped rod. A limiting groove is provided on the surface of the U-shaped rod. The receiving rod is arranged inside the limiting groove. The roller moves and rotates under the action of the inner wall of the sliding groove. The rotation of the roller converts sliding friction into rolling friction, which effectively reduces friction and makes the lifting and lowering of the drone smoother.

[0010] According to the above technical solution, a protrusion is fixedly installed at the bottom of the inner wall of the limit groove, and the top of the protrusion is set as an arc surface. After the receiving rod contacts the protrusion, it continues to move and repeatedly squeezes it, thereby limiting the extension speed of the H-shaped support rod under its action.

[0011] The movable plate is slidably mounted on the upper surface of the movable plate, and the movable plate is slidably mounted on the lower surface of the movable plate, and the movable plate is slidably mounted on the lower surface of the movable plate, and the movable plate is slidably mounted on the lower surface of the movable plate, and the movable plate is slidably mounted on the lower surface of the movable plate, and the movable plate is slidably mounted on the lower surface of the movable plate.

[0012] According to the above technical solution, the movable rod slides through the fixed block, the side of the block away from the L-shaped rod is set to bevel surface two, the movable plate moves through bevel surface two to extrude the block block, the end of the L-shaped rod close to the baffle is set to bevel surface three, the baffle moves through bevel surface three to extrude the L-shaped rod, the side of the movable plate close to the sliding plate is set to bevel surface four, the sliding plate moves through bevel surface four to extrude the movable plate.

[0013] According to the above technical solution, a No. 3 spring is arranged between the receiving plate and the inner wall of the storage slot. Under the action of the receiving plate and the No. 3 spring, the baffle moves in the direction away from the L-shaped rod to close the storage slot. A telescopic elastic rod is arranged between the L-shaped rod and the inner wall of the fixed slot. The telescopic elastic rod can drive the L-shaped rod to reset. A No. 4 spring is arranged between the fixed block and the sliding plate. The No. 4 spring can maintain the stability of the sliding plate to prevent it from shaking.

[0014] The present invention provides a drone with a visual detection function, which has the following beneficial effects: (1) The UAV with visual inspection function moves the toggle plate away from the housing so that the limit rod is separated from the storage groove on the surface of the fixed plate. The movement of the toggle plate drives the triangular block to move away from the contact with the limit block and release the limit. At the same time, the toggle plate is rotated to make the H-shaped support rod extend to support the housing, thereby realizing the rapid storage of the H-shaped support rod, so that the UAV can be folded or retracted when it is not in use. The rotation of the toggle plate allows the limit rod to enter the interior of the slot under the action of the No. 1 spring, and the H-shaped support rod is fixed, thereby preventing the H-shaped support rod from affecting the lifting of the UAV due to lack of support, thereby maintaining the stability of the UAV during the lifting process.

[0015] (2) For the drone with visual inspection function, when the H-shaped support rod is impacted, the H-shaped support rod moves toward the direction close to the U-shaped rod, and drives the H-shaped plate and the receiving rod to move through the receiving block and the connecting rod, so that the roller rotates inside the slide groove. The rotation of the roller converts the sliding friction into rolling friction, which effectively reduces the friction force and makes the drone lifting and lowering process smoother. At the same time, when the H-shaped support rod is reset under the action of the second spring, the receiving rod contacts the protrusion and repeatedly squeezes it, thereby limiting the extension speed of the H-shaped support rod under its action, which can effectively reduce the impact force caused by the H-shaped support rod during the extension process and extend the service life of the equipment.

[0016] (3) For the UAV with visual inspection function, when the impact force on the H-shaped support rod is too large, the H-shaped plate moves to contact and squeeze the sliding plate to move. The movement of the sliding plate drives the L-shaped rod downward under the action of the moving rod and the block. The downward movement of the L-shaped rod releases the limit on the baffle, so that the baffle pops out under the action of the No. 3 spring, drives the visual inspection mechanism to rotate and blocks the storage slot, thereby protecting the visual inspection mechanism and preventing the visual inspection mechanism from colliding with foreign objects due to excessive impact force, thereby preventing the visual inspection mechanism from being damaged. At the same time, during normal use, the L-shaped rod is reset under the action of the telescopic spring rod to fix the baffle, thereby preventing the baffle from shaking during normal use of the UAV, thereby affecting the work of the visual inspection mechanism.
