For example, the first stopper rod 2232 and the second stopper rod 2233 are fixedly connected, and when the ejector 311 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 and is separated from the positioning hole, so that the connection mechanism 300 and the mounting mechanism 200 are separated, and a user only needs to hold the selfie stick body 30 to remove the connector from the connecting groove 211.

Optionally, as shown in fig. 6 and 8, 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 groove 212 remote from the connecting groove 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 214 arranged at intervals, and the first limiting post 2232 and the second limiting post 2233 respectively penetrate through the two through holes 214 correspondingly.

In one embodiment, as shown in fig. 3, 4, 6 and 7, the connection mechanism 300 includes a main shaft body 310 and a shaft housing 320, where the shaft housing 320 is sleeved on the periphery of the main shaft body 310 and is rotationally connected with the main shaft body 310; one end of the main shaft body 310 is connected to one end of the selfie stick body 30. The receiving groove 322 and the positioning hole are both provided on the side wall of the shaft housing 320; the ejector 311 is connected to the main shaft body 310 and is partially located in the receiving groove 322. By rotating the main shaft body 310 relative to the shaft housing 320, the ejector 311 slides in the accommodating groove 322 to eject the first stopper rod 2232 out of the accommodating groove 322, and the second stopper rod 2233 is also disengaged from the positioning hole. 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 311 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.

Alternatively, as shown in fig. 4, the ejector member 311 has an arc surface 3111, the arc surface 3111 is disposed opposite to the side of the main shaft body 310, and the arc surface 3111 extends from the notch of the accommodation groove 322 toward the bottom of the accommodation groove 322. The main shaft body 310 has an initial position relative to the shaft housing 320, when the main shaft body 310 is located at the initial position relative to the shaft housing 320, one end of the ejector 311 abuts against an inner wall of one end of the accommodating groove 322, and one side of the arc surface 3111, 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 3111 or the end of the first stopper rod 2232 facing the axle housing 320 slides directly from the surface of the axle housing 320 into the receiving slot 322, with the first stopper rod 2232 at least partially extending into the receiving slot 322 and the second stopper rod 2233 also at least partially extending 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 3111 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. 2, 6 and 7, the number of the elastic positioning assemblies 220 is two, and the two elastic positioning assemblies 220 are oppositely and vertically 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 pieces 311 is also two, the two ejection pieces 311 are respectively connected to two sides of the main shaft body 310, and each ejection piece 311 is partially located in the corresponding containing groove 322. The two ejection pieces 311 are symmetrically arranged about the center of the main shaft body 310, and the two ejection pieces 311 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 connecting mechanism 300 and the mounting mechanism 200 need to be unlocked, the spindle body 310 is rotated to drive the ejector 311 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 relative to the spindle case 320, one side of each ejection member 311 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.

Further, if the main shaft body 310 is at the initial position and the elastic positioning component 220 is engaged with the shaft housing 320, the first limiting post 2232 is located at the counterclockwise direction of the ejector 311, and when the main shaft body 310 needs to be rotated to the unlocking position, the main shaft body 310 needs to be rotated counterclockwise to eject the limiting piece 223 out of the shaft housing 320; if the main shaft body 310 is at the initial position and the elastic positioning component 220 is engaged with the shaft housing 320, the first limiting post 2232 is located at the clockwise direction of the ejector 311, and the main shaft body 310 needs to be rotated clockwise to eject the limiting member 223 out of the shaft housing 320 when the main shaft body 310 is to be rotated to the unlocking position.

In one embodiment, as shown in fig. 5, a limiting portion 323 is provided on the inner wall of the axle housing 320. As shown in fig. 4, the spindle body 310 is provided with a travel limit groove 312 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 311 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 312. That is, the cooperation of the travel limit groove 312 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 that the ejector 311 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. 4 and 7, a first magnetic member 324 is disposed on an outer wall of the shaft housing 320, and a second magnetic member 313 is disposed on an outer wall of the main shaft body 310, and a magnetic attraction is provided between the second magnetic member 313 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 313, 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 311 is positioned at one side of the receiving groove 322 without interfering with the first stopper rod 2232 protruding into the receiving groove 322.

Optionally, two first magnetic pieces 324 are provided, and the two first magnetic pieces 324 are respectively located at two sides of the main shaft body 310; the two second magnetic pieces 313 are also two, the two second magnetic pieces 313 are respectively positioned at two sides of the axle housing 320, and the two second magnetic pieces 313 are in one-to-one correspondence with the two first magnetic pieces 324. By providing the two first magnetic members 324 and the two second magnetic members 313, the reaction speed of the main shaft body 310 with respect to the shaft housing 320 can be increased when the main shaft body 310 is returned to the reset state, and the stability of the main shaft body 310 with respect to the shaft housing 320 can be increased when the main shaft body is in the reset state.

Optionally, a magnetic member mounting groove is provided on an inner wall of the connection groove 211, and a third magnetic member 215 capable of magnetically attracting the second magnetic member 313 is provided in the magnetic member mounting groove. For example, when two elastic positioning members 220 are provided, the third magnetic member 215 is disposed between the two elastic positioning members 220.
