Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Refer to Figure 1 - Figure 3, A device for detecting the extreme position of the frame of an object to be photographed, including a base 1. The bottom of the base 1 is rotatably connected with a moving wheel 3. By arranging a handle and a moving wheel 3 on the outer wall of the base 1, it is convenient for the staff to push the whole device to move, facilitating the movement of the device to a designated position for shooting during the shooting process. The inner surface of the base 1 is provided with an anti-photographed object mechanism. The anti-photographed object mechanism includes a first pulley 11. The outer surface of the first pulley 11 is rotatably connected to the top end of the inner surface of the base 1, enabling the first pulley 11 to rotate on the top end of the inner surface of the base 1. The top end of the outer surface of the base 1 is fixedly connected with a support rod 2, providing a fixed support effect for the support rod 2 by the top end of the outer surface of the base 1. The inner wall of the base 1 is slidably connected with a traction rope 17, enabling the traction rope 17 to move horizontally along the inner surface of the base 1. The outer surface of the traction rope 17 is fixedly connected with the outer surface of the first pulley 11, enabling the first pulley 11 to wind and lengthen the traction rope 17 when rotating. The outer surface of the traction rope 17 is slidably connected with the left outer surface of the support rod 2, enabling the traction rope 17 to move vertically along the left side of the support rod 2. The top end of the traction rope 17 is in contact connection with a second pulley 10, enabling the downward movement to be converted into an upward movement under the drive of the second pulley 10 for the traction rope 17. The outer surface of the second pulley 10 is rotatably connected to the top end of the inner surface of the support rod 2, enabling the second pulley 10 to rotate on the top end of the inner surface of the support rod 2. One end of the traction rope 17 is fixedly connected with a slider 4, enabling the slider 4 to move upward when one end of the traction rope 17 is pulled. The front end of the outer surface of the base 1 is fixedly connected with a motor 20, providing a fixed support effect for the motor 20 by the front end of the outer surface of the base 1. The output end of the motor 20 is fixedly connected with the outer surface of the first pulley 11, enabling the motor 20 to drive the first pulley 11 to rotate. A sensor is connected to the motor 20. During the process of magnifying the picture, the sensor drives the motor 20 to operate. The sensor is a prior art and will not be described in detail here.

[0034] Refer to Figure 1 , Figure 4 - Figure 5The outer surface of the slider 4 is slidably connected to the inner surface of the support rod 2, so that the slider 4 can move vertically along the inner wall of the support rod 2. The right side of the outer surface of the slider 4 is fixedly connected to the connecting rod 5, so that when the slider 4 moves vertically, it can drive the connecting rod 5 to move together. The right side of the inner surface of the connecting rod 5 is plugged with a microphone 7, so that the top of the microphone 7 can move vertically along the right side of the inner surface of the connecting rod 5. The inner wall of the microphone 7 is elastically connected to an inclined block 16 through a spring B19, so that the inclined block 16 can always keep the effect of moving outward without being affected by external forces. The outer wall of the inclined block 16 is slidably connected to the inner wall of the microphone 7, so that the inclined block 16 can move laterally along the inner wall of the microphone 7. The outer wall of the inclined block 16 is clamped with the inner wall of the connecting rod 5, so that the microphone 7 can be fixed to the inner wall of the connecting rod 5 due to the clamping of the inclined block 16 and the connecting rod 5. The top of the connecting rod 5 is elastically connected to a toggle ring 13 through a spring A14, so that the toggle ring 13 can always keep the effect of moving upward without being affected by external forces.

[0035] Reference Figure 5 - Figure 6 The bottom end of the toggle ring 13 is fixedly connected with an inclined column 15, so that when the toggle ring 13 moves vertically, it can drive the inclined column 15 to move together. The outer wall of the inclined column 15 is slidably connected to the inner wall of the connecting rod 5, so that the inclined column 15 can move vertically along the inner wall of the connecting rod 5. The bottom end of the inclined column 15 is in contact with the top of the inclined block 16, so that when the inclined column 15 moves downward, it can squeeze the inclined surface of the inclined block 16, so that the inclined block 16 moves outward, thereby releasing the effect of fixing the microphone 7. The bottom end of the connecting rod 5 is fixedly connected with a sleeve rod 9, through the connecting rod 5 The bottom end provides a fixed support effect for the sleeve rod 9. The inner wall of the sleeve rod 9 is elastically connected to the rod body 12 through a spring C18, so that the rod body 12 can always keep moving downward without being affected by external forces. The bottom end of the rod body 12 is fixedly connected to a protective ring 8, so that when the protective ring 8 moves vertically, it can drive the rod body 12 to move vertically. The protective ring 8 is made of rubber, so that when the protective ring 8 contacts an object, it can cause a deformation effect. The left side of the base 1 is fixedly connected to a handle, which can save more effort when moving the base 1.

[0036] Reference Figure 4 - Figure 6One end of the spring B19 is fixedly connected to the inner wall of the microphone 7, and the other end of the spring B19 is fixedly connected to the outer wall of the inclined block 16, so that when the inclined block 16 stops being squeezed, the inclined block 16 can move outward due to the elastic force of the spring B19 and snap into contact with the inner wall of the connecting rod 5. One end of the spring A14 is fixedly connected to the top of the connecting rod 5, and the other end of the spring A14 is fixedly connected to the bottom end of the toggle ring 13, so that when the toggle ring 13 stops being pressed, the toggle ring 13 can drive the inclined column 15 to move upward due to the elastic force of the spring A14. One end of the spring C18 is fixedly connected to the inner wall of the sleeve rod 9, and the other end of the spring C18 is fixedly connected to the top of the rod body 12, so that when the protective ring 8 stops being squeezed and drives the rod body 12 to move vertically, the rod body 12 can be reset due to the elastic force of the spring C18.

[0037] Working principle: When using the device, when the base 1 is moved to the left, the sensor starts the motor 20 to drive the first pulley 11 to rotate and reel in the traction rope 17. Then the slider 4 is driven by the traction rope 17 to drive the connecting rod 5 and the microphone 7 to move upward. When the camera is moved away, the microphone 7 can be prevented from being illuminated by the camera.

[0038] When replacing the microphone 7, first press the toggle ring 13 to drive the inclined column 15 to move downward, so that the bottom end of the inclined column 15 squeezes the inclined surface of the inclined block 16, so that the inclined block 16 moves inward, and at the same time releases the fixation of the microphone 7, and then pulls out the microphone 7, and then plugs the new microphone 7 into the inner wall of the connecting rod 5, and then the inclined surface of the inclined block 16 will be squeezed by the inner wall of the connecting rod 5, so that the microphone 7 will not be blocked when it is plugged in, and then when the microphone 7 moves to the specified position, the inclined block 16 will move outward due to the elastic force of the spring B19, and engage with the inner wall of the connecting rod 5, so that the microphone 7 is fixed to the inner wall of the connecting rod 5.

[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.
