[0023] Please refer to Figures 2-6 The utility model provides a lens barrel structure of lens, and telescope accessory 4 includes external thread 41, threaded sleeve 42, telescope barrel 43, connecting sleeve 44, bolt 45, inner cavity 46, rebounder 47, connecting seat 48 and jack 49, the top edge of lens body 1 is provided with external thread 41, threaded sleeve 42 is sleeved on the top surface of lens body 1, and is screwed with lens body 1 through external thread 41, the top of threaded sleeve 42 is equipped with telescope barrel 43, and threaded sleeve 42 is hinged with telescope barrel 43 through the side part, the lower end side of telescope barrel 43 is installed with connecting sleeve 44, bolt 45 is slidably installed in the inner side of connecting sleeve 44, and bolt 45 is longitudinally penetrated in the upper and lower two parts of connecting sleeve 44, the inner cavity 46 is provided in the middle part of bolt 45, and the rebounder 47 is screw mounted in the middle part of the inner side of connecting sleeve 44, the rebounder 47 is located in the inner cavity 46, and the top telescopic end of rebounder 47 is connected with the top surface of inner cavity 46, so that bolt 45 is connected with rebounder 47, the side part of threaded sleeve 42 is integrally provided with connecting seat 48, and jack 49 is provided in the upper and lower two parts of connecting seat 48, and bolt 45 can be inserted with the inner side of jack 49.

[0024] Further, the number of rotation joints of threaded sleeve 42 and external thread 41 is not less than 3, which ensures the connection stability of telescope barrel 43 and lens body 1.

[0025] Further, the outer diameter size of telescope barrel 43 and lens body 1 is matched, so that telescope barrel 43 and lens body 1 have the same holding feeling, which will not cause awkward operation and improve the use experience.

[0026] Further illustrate, the rotatable angle between the telescope barrel 43 and the threaded sleeve 42 is not less than 180 degrees, allowing the telescope barrel 43 to be turned and opened from the top of the threaded sleeve 42, so as to be out of the field of view of the optical element 3. The user can adjust the position of the telescope barrel 43 according to the use requirement, without frequent disassembly and assembly operations.

[0027] Further illustrate, the telescope barrel 43 is hinged with the threaded sleeve 42 by a damping hinge, so that the telescope barrel 43 and the threaded sleeve 42 have a large rotational torque, providing a self-locking effect for the telescope barrel 43.

[0028] Further illustrate, when the plug 45 and the socket 49 are in the plug-in state, the telescope barrel 43 coincides with the axial line of the lens main body 1, so as to accurately lock the telescope barrel 43 in the position directly opposite to the lens main body 1.

[0029] The working principle is as follows:

[0030] First, first, the lens main body 1 is connected and installed with the camera, and when performing the shooting operation, the focusing ring 2 is turned to control the movement of the optical element 3 in the lens main body 1, so as to realize the focusing operation.

[0031] Second, by providing the telescope accessory 4 at the top end of the lens main body 1, when the lens main body 1 needs to be equipped with the telescope barrel 43, the threaded sleeve 42 is screwed to the top end surface of the lens main body 1 through the external thread 41, so as to complete the assembly operation. When the telescope barrel 43 is needed to be used, the telescope barrel 43 is turned until it is connected with the threaded sleeve 42, and then the plug 45 is pressed downward to trigger the rebounder 47 to retract, so that the bottom end of the plug 45 is inserted into the inside of the socket 49, the connecting sleeve 44 and the connecting seat 48 are clamped together, so as to lock the telescope barrel 43 at the current angle. At this time, the telescope barrel 43 is directly opposite to the lens main body 1, and the lens main body 1 can perform the long-distance shooting through the magnifying effect of the telescope barrel 43, so as to improve the shooting effect.

[0032] Third, when the telescope barrel 43 is not used temporarily, the plug 45 is pressed downward to trigger the rebounder 47 to pop up, so that the bottom end of the plug 45 is separated from the inside of the socket 49, so as to release the angle locking of the telescope barrel 43. Then, the telescope barrel 43 can be turned and opened from the top of the threaded sleeve 42, so as to be out of the field of view of the optical element 3. The user can adjust the position of the telescope barrel 43 according to the use requirement, without frequent disassembly and assembly operations.
