[0030] Furthermore, a cavity 202a is provided inside the end of the first telescopic rod 202 close to the camera 101, and the cavity 202a is divided into a locking section 202a-1 and a limiting section 202a-2.

The end of the rotating column 204c is fixedly connected to the limiting component 301, bearing the weight of the camera 101.

[0031] Example 2

[0032] Reference Figures 1 to 4, this embodiment is different from the first embodiment in that: the adjusting component 203 includes an adjusting rope 203a, a transmission belt 203b and a transmission rod 203c, the adjusting rope 203a is generally "U"-shaped, the adjusting rope 203a passes through the handle 201 and is connected to the end of the transmission belt 203b, the transmission belt 203b is generally in an inverted "U" shape, a first tooth block is arranged on the inner side of the transmission belt 203b, a second tooth block is arranged on the end of the transmission rod 203c in contact with the transmission belt 203b, a first bevel gear 203c-1 is arranged on the end of the transmission rod 203c away from the transmission belt 203b, the first tooth block is meshed with the second tooth block, it is worth noting that a first baffle plate 203d is fixedly connected to the adjusting rope 203a, the first baffle plate 203d is made of rubber, and the reason for using rubber material is that it can produce deformation and has a high friction coefficient.

[0033] Specifically, the rotating component 204 includes a first rotating rod 204a, a second rotating rod 204b and a rotating column 204c. The end of the first rotating rod 204a is fixedly connected to the second bevel gear 204a-1, the outer wall of the second rotating rod 204b is provided with a transmission gear block 204b-1, and the outer wall of the rotating column 204c is provided with a thread; the first bevel gear 203c-1 is meshed with the second bevel gear 204a-1, and the second bevel gear 204a-1 is meshed with the transmission gear block 204b-1.

[0034] Furthermore, the limiting component 301 includes a limiting rod 301a and a limiting plate 301b. The limiting rod 301a is hollow inside and is fixedly connected to the end of the rotating column 204c. The limiting rod 301a is made of deformable metal material, and the limiting plate 301b is fixedly connected to the end of the limiting rod 301a.

[0035] The rest of the structure is the same as that of Example 1.

[0036] Example 3

[0037] Reference Figures 1 to 5 , this embodiment is different from the above embodiments in that: the ejection component 302 includes a rubber telescopic rod 302a, a tension spring 302b and a reset rope 302c, the end of the rubber telescopic rod 302a is connected to the connecting seat 102, one end of the rubber telescopic rod 302a is fixedly connected to the bottom end of the inner wall of the telescopic limiting column, the two ends of the tension spring 302b are fixedly connected to the two ends inside the rubber telescopic rod 302a, one end of the reset rope 302c is fixedly connected to the end of the rubber telescopic rod 302a, and the other end of the reset rope 302c passes through the hand-held mechanism 200 and is fixedly connected to the first limiting ball 302d.

[0038] Specifically, the lifting component 303 includes a linkage component 303a, a resistance component 303b and a locking component 303c. The linkage component 303a rotates synchronously with the camera 101, and the resistance component 303b is used to control the locking state of the locking component 303c.

[0039] The linkage assembly 303a includes a rotating ring 303a-1, a connecting block 303a-2 and a pulling rope 303a-3. The rotating ring 303a-1 is connected to the end of the first telescopic rod 202, the connecting block 303a-2 is fixedly connected to the rotating ring 303a-1, one end of the pulling rope 303a-3 is connected to the camera 101, and the other end of the pulling rope 303a-3 passes through the conflict assembly 303b, the connecting block 303a-2 and the handle 2 01 is fixedly connected with the second limiting ball 303a-5; an interference groove 303a-4 is opened in the middle of the rotating ring 303a-1, and a strip plate is fixedly connected to the end of the interference groove 303a-4 away from the camera 101. It is worth noting that the end opening of the interference groove 303a-4 away from the strip plate is smaller than the opening connecting the bottom groove and the strip plate, and the function of the strip plate is to prevent the interference component 303b from passing through the bottom end of the interference groove 303a-4.

[0040] Furthermore, the resistance component 303b includes a resistance block 303b-1, a friction strip 303b-2 and a return spring 303b-3. A slope is arranged on one side of the resistance block 303b-1, the friction strip 303b-2 is arranged on both sides of the resistance block 303b-1, and the return spring 303b-3 is arranged at the bottom of the resistance block 303b-1. It is worth noting that when the friction strip 303b-2 just enters the resistance groove 303a-4, its side wall fits with the end opening of the resistance groove 303a-4, so that the user pulls the tension rope 303a-3 downward through the tension rope 303a-3. When the tension rope 303a-3 drives the friction strip 303b-2 on the resistance block 303b-1 to enter the resistance groove 303a-4, the user will feel a sense of pause. This is to remind the user that if the user continues to pull downward, the viewing angle of the camera 101 will be pulled upward.

[0041] Furthermore, the locking assembly 303c includes a resistance rod 303c-1 and a locking groove 303c-2, the resistance rod 303c-1 passes through the connecting block 303a-2 and the rotating ring 303a-1, one end of the resistance rod 303c-1 located at the connecting block 303a-2 is set as an arc surface, the other end of the resistance rod 303c-1 is set in a strip shape, the locking groove 303c-2 is set on the outer wall of the first telescopic rod 202 close to the camera 101, the resistance rod 303c-1 is adapted to the locking groove 303c-2, and a tension spring is set between the resistance rod 303c-1 and the connecting block 303a-2. It is worth noting that when the resistance rod 303c-1 is squeezed by the resistance block 303b-1, it is pushed to When the telescopic rod moves in the direction of the telescopic rod, the end of the resistance rod 303c-1 is inserted into the locking groove 303c-2, so that the relative position of the rotating ring 303a-1 and the telescopic rod is fixed. At this time, the viewing angle of the camera 101 is pulled upward, and the camera 101 will not move around due to the pulling force, resulting in an uncontrollable angle. When there is no external force pulling the resistance block 303b-1, the resistance block 303b-1 moves upward under the action of the reset spring 303b-3 and returns to its initial state. At this time, the resistance rod 303c-1 also moves toward the connecting block 303a-2 under the action of the tension spring. At this time, the resistance rod 303c-1 is no longer in contact with the locking groove 303c-2, that is, the resistance rod 303c-1 simultaneously returns to its initial state.

[0042] The rest of the structure is the same as that of Example 2.

[0043] Operation process: When the staff needs to inspect equipment, cables, instruments and other equipment, they first need to hold the handle 201, then pull open the first telescopic rod 202, and then lift the first telescopic rod 202 to inspect the equipment through the camera 101. A connection system can be set up inside the camera 101 to remotely transmit the content captured by the camera 101 to the display screen, and the staff can perform screenshot editing and other tasks through the display screen.

[0044] When encountering corners, holes, confined spaces, etc. during inspection, first, the adjustment rope 203a under the handle 201 can be pulled. When the adjustment rope 203a moves up and down, the transmission belt 203b can be driven to move up and down at the same time. When the transmission belt 203b moves up and down, the first tooth block is engaged with the second tooth block on the transmission rod 203c to drive the transmission rod 203c to rotate at the same time. When the transmission rod 203c rotates, the second rotating rod 204b is driven to rotate at the same time through the first rotating rod 204a. When the second rotating rod 204b rotates, the limit rod 301a and the rubber telescopic rod 302a drive the connecting seat 102 and the camera 101 to rotate at the same time, so as to achieve the purpose of adjusting the horizontal angle of the camera 101.

[0045] It should be noted that a first baffle 203d is fixedly connected to one end of the adjustment rope 203a close to the handle 201, and an adjustment through hole adapted to the adjustment rope 203a is opened on the handle 201. The opening of the adjustment through hole close to the first baffle 203d has the same diameter as the first baffle 203d, and the diameter of the other end of the adjustment through hole is larger than the diameter of the first baffle 203d. The purpose of such a setting is that when the adjustment rope 203a is pulled to drive the first baffle 203d to move downward to the end opening of the adjustment through hole, the distance is exactly the distance for rotating the camera 101 horizontally 360°. When the first baffle 203d moves to the end opening of the adjustment through hole, the first baffle 203d The friction with the inner wall of the adjustment through hole produces a sense of pause, thereby reminding the user that the camera 101 has rotated 360 degrees. Continuing to pull the adjustment rope 203a downward will drive the limit column to move downward along the inner wall of the first telescopic rod 202. When the limit column moves downward along the inner wall of the first telescopic rod 202, the end of the limit column will be deformed along the inner wall of the first telescopic rod 202, causing the diameter of the end of the limit column to increase. When the diameter of the limit column increases, the rubber telescopic rod 302a is no longer limited. At this time, the rubber telescopic rod 302a extends upward from the first telescopic rod 202 under the elastic force of the tension spring 302b. At this time, the camera 101 moves upward simultaneously with the rubber telescopic rod 302a.

[0046] It should be noted that the rubber telescopic rod 302a is made of rubber material, and its interior is hollow to place the tension spring 302b. The reason for using rubber material is that rubber has a certain hardness to support the weight of the camera 101, and at the same time, rubber can produce deformation, which is convenient for inserting into holes or corners, thereby solving the problem of inconvenient inspection of equipment located in holes and corners.

[0047] When the rubber telescopic rod 302a extends out of the first telescopic rod 202, when it is difficult to find the right angle for inspection when facing some equipment in high places, the tension rope 303a-3 can be pulled downward. When the tension rope 303a-3 moves downward, it drives the resistance block 303b-1 to move downward. When the resistance block 303b-1 enters the resistance groove 303a-4, the resistance rod 303c-1 is squeezed by the resistance block 303b-1. When it moves toward the telescopic rod, the end of the resistance rod 303c-1 is inserted into the locking groove 303c-2, so that the relative position of the rotating ring 303a-1 and the telescopic rod is fixed. At this time, the viewing angle of the camera 101 can be pulled upward to solve this problem.

[0048] When the inspection work is completed, the reset rope 302c is pulled to pull the rubber telescopic rod 302a back into the first telescopic rod 202, and then the adjustment rope 203a is pulled to rotate the transmission rod 203c in the opposite direction, so that the transmission rod 203c drives the limit column to move upward through the first rotating rod 204a and the second rotating rod 204b. When the first baffle 203d extends from the end of the adjustment slot 201a, it indicates that the limit column returns to the initial position. At this time, the limit column limits the rubber telescopic rod 302a, and limits the rubber telescopic rod 302a to the end of the first telescopic rod 202. At this time, the device returns to its initial state.
