Further, the projected maximum outer diameter of the selfie stick body 30 is less than a 23mm circle to ensure that the outer diameter of the selfie stick body 30 is small enough to achieve a "stealth" effect.

Further, the connecting mechanism 300 has a substantially cylindrical or polygonal column shape, so that the dimension thereof in the length direction is uniform, and also has an external shape closer to the shape of the selfie stick body 30. And first mounting structure 360 sets up in cylindric or the top surface of many prisms coupling mechanism 300, second mounting structure 370 sets up in cylindric or the bottom surface of many prisms coupling mechanism 300, coupling mechanism 300's bottom can be dismantled with from rapping bar body 30 like this, coupling mechanism 300's top can be dismantled with shooting equipment and be connected, thereby make from rapping bar body 30, coupling mechanism 300 and shooting equipment can dismantle in proper order and connect, when user's hand is held from rapping bar body 30, shooting equipment is located the position of keeping away from the hand, thereby conveniently take a photo certainly, and in shooting process, because coupling mechanism 300 and from rapping bar body 30 are tiny enough, therefore have "stealth" effect.

The main shaft body 310 is used for detaching the coupling mechanism 300 from the fixing mechanism 40 by releasing the coupling of the shaft housing 320 to the fixing mechanism 40 by rotating the main shaft body 310 relative to the shaft housing 320. When a user needs to take a picture and take the selfie stick body 30 from the fixing mechanism 40, the user can rotate the selfie stick body 30 to rotate the main shaft body 310 relative to the shaft housing 320 to release the connection between the shaft housing 320 and the fixing mechanism 40, so that the user can take the connecting mechanism 300 from the fixing mechanism 40.

Further, as shown in fig. 2, 3 and 5, a bearing 330 is provided between the main shaft body 310 and the shaft housing 320 so that the main shaft body 310 can smoothly rotate with respect to the shaft housing 320. The axle housing 320 is a sleeve having a longitudinal cross-section that is generally inverted U-shaped. A bearing 330 is located in the interior cavity of the axle housing 320 and adjacent the lower end opening 327. The main shaft body 310 has a blocking portion 313 at one end thereof, the blocking portion 313 having a shape corresponding to the shape of the lower end opening 327, the blocking portion 313 being used to close the lower end opening 327 of the shaft housing 320, so as to isolate the space inside the shaft housing 320 from the outside at the end opening of the shaft housing 320, thereby preventing the bearing 330 from being directly exposed to the outside space of the shaft housing 320. For example, the lower end opening 327 of the shaft housing 320 is circular, the barrier 313 is circular, and the size of the barrier 313 is adapted to the size of the opening of the bearing 330.

The locating portion 321 is a locating hole formed in the axle housing 320, the axle housing 320 is further provided with an accommodating groove 322, the accommodating groove 322 and the locating hole are arranged at intervals up and down, the accommodating groove 322 and the first limit post 2232 are correspondingly arranged, the locating hole and the second limit post 2233 are correspondingly arranged, when the connecting mechanism 300 is in fit and butt joint with the inner wall of the connecting groove 211, the first limit post 2232 extends into the accommodating groove 322 through the mounting groove 212, and meanwhile, the second limit post 2233 extends into the locating hole through the mounting groove 212, so that the connecting mechanism 300 is fixed in the connecting groove 211, and connection between the connecting mechanism 300 and the mounting structure is completed.

Further, as shown in fig. 2, 5 and 6, the main shaft body 310 is connected with an ejector 315, and the ejector 315 is slidably disposed in the accommodating groove 322. By rotating the main shaft body 310 relative to the shaft housing 320, the ejector 315 can slide in the accommodating groove 322, and the ejector 315 can push the first limiting post 2232 out of the accommodating groove 322 and simultaneously drive the second limiting post 2233 to be separated from the positioning hole when sliding in the accommodating groove 322. For example, the first stopper rod 2232 and the second stopper rod 2233 are fixedly connected, and when the ejector 315 slides to eject the first stopper rod 2232 from the receiving groove 322, the second stopper rod 2233 also moves along with the first stopper rod 2232 to disengage from the positioning hole, so as to separate the connecting mechanism 300 from the mounting mechanism 200, and only a user needs to hold the selfie stick body 30 to remove the connecting mechanism 300 from the connecting groove 211. In this way, the user can hold the selfie stick body 30 with one hand, so that the connecting mechanism 300 can be placed into the connecting slot 211 and clamped with the mounting mechanism 200, or can rotate the selfie stick body 30 with one hand to drive the main shaft body 310 to rotate synchronously, so that the ejector 315 slides in the accommodating slot 322 to eject the first spacing post 2232 out of the accommodating slot 322, and meanwhile, the second spacing post 2233 is separated from the positioning hole, thereby completing the separation of the connecting mechanism 300 and the mounting mechanism 200. That is, the user can complete the installation and the removal of the connection mechanism 300 and the installation mechanism 200 with one hand, and the operation is very convenient.

Optionally, as shown in fig. 5, the elastic positioning assembly 220 further includes a fixing plate 221 and an elastic member 222, where the fixing plate 221 is disposed at an opening of the mounting slot 212 away from the connecting slot 211; one end of the elastic member 222 is connected with the fixing plate 221, the other end is connected with the limiting member 223, and the elastic member 222 is used for keeping the limiting member 223 in a mechanically coupled state with the positioning portion 321; the opening of the mounting groove 212 far away from the fixing plate 221 is provided with a limiting plate 213, the limiting plate 213 is provided with two through holes arranged at intervals, and the first limiting post 2232 and the second limiting post 2233 respectively correspondingly penetrate through the two through holes. The limiting member 223 further includes a connecting block 2231, the first limiting post 2232 and the second limiting post 2233 are connected to the same side of the connecting block 2231, and a side of the connecting block 2231 facing away from the first limiting post 2232/the second limiting post 2233 is connected to the elastic member 222. When the limiting member 223 is not subjected to external force, the elastic member 222 is in a compressed state, the side of the connecting block 2231 facing away from the elastic member 222 is abutted against the limiting plate 213, and the first limiting post 2232 and the second limiting post 2233 are respectively inserted into the corresponding through holes.

Alternatively, as shown in fig. 2, the ejector 315 has an arcuate surface 3151, the arcuate surface 3151 being disposed opposite to a surface of the main shaft body 310, the arcuate surface 3151 extending from a notch of the receiving groove 322 toward a bottom of the receiving groove 322. The main shaft body 310 has an initial position relative to the shaft housing 320, when the main shaft body 310 is positioned at the initial position relative to the shaft housing 320, one end of the ejector 315 abuts against an inner wall of one end of the accommodating groove 322, and one side of the arc surface 3151, which is close to the notch, is flush with an outer wall of the shaft housing 320. During placement of the coupling mechanism 300 in the coupling slot 211, the end of the first stopper rod 2232 facing the axle housing 320 slides from the surface of the axle housing 320 onto the arcuate surface 3151, or the end of the first stopper rod 2232 facing the axle housing 320 slides from the surface of the axle housing 320 directly into the receiving slot 322, with the first stopper rod 2232 at least partially protruding into the receiving slot 322 and the second stopper rod 2233 also at least partially protruding into the locating hole when the axle housing 320 is in mating abutment with the inner wall of the coupling slot 211. When the main shaft body 310 is rotated to the end of the arc surface 3151 flush with the outer wall of the shaft housing 320 to abut against the first stopper rod 2232, the stopper 223 is disengaged from the receiving groove 322 and the positioning hole.

In one embodiment, as shown in fig. 5, there are two elastic positioning assemblies 220, and the two elastic positioning assemblies 220 are oppositely disposed on the mounting bracket main body 210 and are respectively located at two sides of the connecting slot 211. Accordingly, both sides of the shaft housing 320 are provided with positioning holes and receiving grooves 322 corresponding to the respective elastic positioning members 220. The number of the ejection members 315 is two, the two ejection members 315 are respectively connected to two sides of the spindle body 310, and each ejection member 315 is partially located in the corresponding receiving groove 322. The two ejection members 315 are symmetrically arranged with respect to the center of the main shaft body 310, and the two ejection members 315 are in one-to-one correspondence with the two elastic positioning assemblies 220.

It can be appreciated that when the connection mechanism 300 is abutted against the inner wall of the connection slot 211, the two limiting members 223 on the mounting bracket main body 210 are respectively located at two sides of the connection mechanism 300, and the two limiting members 223 are respectively clamped with the connection mechanism 300 from two sides, so that the connection stability of the connection mechanism 300 and the mounting mechanism 200 is increased. When the connection mechanism 300 and the installation mechanism 200 need to be unlocked, the spindle body 310 is rotated to drive the ejector 315 to slide in the accommodating groove 322, so that the corresponding first limiting post 2232 is ejected out of the accommodating groove 322. Specifically, when the spindle body 310 is located at the initial position with respect to the spindle case 320, one side of each ejection member 315 abuts against an inner wall of one end of the corresponding receiving groove 322. The main shaft body 310 has an unlocking position with respect to the shaft housing 320, and the stopper 223 is simultaneously disengaged from the receiving groove 322 and the positioning hole when the main shaft body 310 is rotated from the initial position to the unlocking position with respect to the shaft housing 320.

In one embodiment, as shown in fig. 7, a limiting portion 323 is provided on the inner wall of the axle housing 320. As shown in fig. 2 and 3, the spindle body 310 is provided with a travel limit groove 316 adapted to the limit portion 323. When the connecting mechanism 300 is unlocked from the mounting mechanism 200 by rotating the main shaft body 310, the ejector 315 ejects the first stopper rod 2232 out of the accommodating groove 322 when the stopper 323 rotates to abut against the inner wall of one end of the stroke-limiting groove 316. That is, the cooperation of the travel limit groove 316 and the limit portion 323 is used to limit the rotation angle of the spindle body 310 relative to the spindle housing 320, so as to avoid unlocking failure caused by the fact that the ejector 315 no longer acts on the first limit post 2232 after the spindle body 310 rotates from the initial position to the unlocking position, and the first limit post 2232 is re-inserted into the accommodating groove 322.

In one embodiment, as shown in fig. 2 and 6, a first magnetic member 324 is disposed on an outer wall of the shaft housing 320, and a second magnetic member 317 is disposed on an outer wall of the main shaft body 310, and a magnetic attraction is provided between the second magnetic member 317 and the first magnetic member 324. Under the condition that the main shaft body 310 is not subjected to external force, under the action of the magnetic attraction force between the first magnetic piece 324 and the second magnetic piece 317, the main shaft body 310 is in a reset state relative to the shaft housing 320, and after the connecting mechanism 300 is removed from the mounting mechanism 200 by a user, the main shaft body 310 and the shaft housing 320 can be automatically reset. In the reset state, the ejector 315 is located at one side of the receiving groove 322 without interfering with the first stopper rod 2232 protruding into the receiving groove 322.

Further, as shown in fig. 2 and 5, a torsion spring 350 is provided between the shaft housing 320 and the main shaft body 310, and the torsion spring 350 is spirally wound around the outer periphery of the main shaft body 310. One end of the torsion spring 350 is fixed to the shaft housing 320, and the other end is fixed to the main shaft body 310. Specifically, the torsion spring 350 has a first fixed end and a second fixed end. As shown in fig. 7, the inner wall of the axle housing 320 has a first securing notch 326. As shown in fig. 3, the mandrel sleeve 312 has a second fixing notch 3121, and the first fixing end is fixed in the first fixing notch 326, and the second fixing end is fixed in the second fixing notch 3121. When the spindle body 310 is in the reset state, the torsion spring 350 is in a stretched state to apply a pre-tightening force between the spindle body 310 and the spindle case 320. In the reset state, when the main shaft body 310 needs to be rotated from the initial position to the unlocking position relative to the shaft housing 320, the elastic force exerted by the torsion spring 350 is gradually increased during the continuous rotation, and the magnetic attraction between the first magnetic member 324 and the second magnetic member 317 is continuously reduced, so that the magnetic attraction between the first magnetic member 324 and the second magnetic member 317 and the elastic force exerted by the torsion spring 350 are overlapped to form complementation, and the external force exerted by the user during the rotation of the main shaft body 310 is substantially uniform, thereby improving the experience of the user during the rotation of the selfie stick body 30 and making the rotation smoother.

Optionally, a magnetic member mounting groove is provided on the inner wall of the connecting groove 211, and a third magnetic member 214 capable of magnetically attracting with the second magnetic member 317 is provided in the magnetic member mounting groove. For example, when two elastic positioning members 220 are provided, the third magnetic member 214 is disposed between the two elastic positioning members 220. By providing the third magnetic member 214, the second magnetic member 317 on the shaft housing 320 and the third magnetic member 214 can be attracted to each other, so that the connection mechanism 300 can be guided when the connection assembly is placed in the connection groove 211, and an error in the direction in which the connection assembly is placed in the connection groove 211 can be avoided.

Further, as shown in fig. 4, the coupling groove 211 has a fitting groove 215 on an inner wall thereof, and the fitting groove 215 communicates with the magnetic member mounting groove. As shown in fig. 2, a magnetic member fixing frame 325 adapted to the fitting groove 215 is provided on the outer wall of the shaft housing 320, and the second magnetic member 317 is fixed in the magnetic member fixing frame 325. When the connection mechanism 300 is placed in the connection groove 211 and the outer wall of the shaft housing 320 abuts against the inner wall of the connection groove 211 under the guidance of the third magnetic member 214, the magnetic member fixing frame 325 is embedded in the matching groove 215, so that the shaft housing 320 does not rotate relative to the mounting bracket main body 210 when the main shaft body 310 is rotated to unlock the connection mechanism 300 from the mounting bracket main body 200, and the failure of unlocking caused by reinsertion of the first limiting post 2232 into the receiving groove 322 due to rotation of the shaft housing 320 relative to the mounting bracket main body 210 after the second limiting post 2233 is separated from the positioning hole is avoided.

Alternatively, as shown in fig. 2 and 5, a nut 318 is attached to the spindle screw 311, and by rotating the nut 318 to any position, the angle of the image pickup apparatus attached to the spindle screw 311 can be adjusted.
