The elastic force of the bayonet lock spring 94 is designed to move the bayonet lock limiting seat 93 in a direction close to the third bevel gear 83 so that the limiting projection 931 and the convex portion 831a or the concave portion 831b of the third bevel gear 83 abut against each other.

[0037] When the operating element 6 is operated, the operating element 6 drives the transmission rod assembly 84 so that the transmission rod assembly rotates, and the transmission rod assembly 84 drives the first bevel gear 81 to rotate about its own axis, the second bevel gear 82 rotates together with the first bevel gear 81, and the third bevel gear 83 rotates together with the second bevel gear 82.When the third bevel gear 83 rotates for the first time, the transmission projection 833 disposed on the third bevel gear 83 rotates from the first side wall of one driven projection 711 to the second side wall of the other driven projection 711 (or rotates from the second side wall of one driven projection 711 to the first side wall of the other driven projection 711), and then the transmission projection 833 abuts against the driven projection 711, and at the same time, the contact point of the bayonet lock assembly 9 and the third bevel gear 83 moves from the convex portion 831a to the concave portion 831b. At this time, the bayonet lock assembly 9 detaches from the mounting platform 7, and the mounting platform 7 fixed to the platform connection column 71 can rotate together with the third bevel gear 83.When the third bevel gear 83 rotates a certain angle, the bayonet lock assembly 9 returns to the convex portion 831a, the bayonet lock assembly 9 accurately engages the positioning hole 7a provided on the mounting platform 7, and one end of the bayonet lock assembly 9 again projects into the positioning hole 7a to secure the mounting platform 7, so that the mounting platform 7 is fixed at the set rotation angle. By operating the operating element 6 in the reverse direction, the mounting platform 7 can return to the original angle in the same way. The rotation angle is set by design and is 180 degrees in the present embodiment.

[0038] The operation of this selfie stick is as follows: The operator installs the recording device on the mounting platform 7, extends the outer tube unit 2 to the desired length, and then rotates the angle rotation element 4 to adjust the recording device to the desired shooting angle. By holding the outer tube 1, the control element 6 can control the mounting platform 7 and rotate it along its own mounting axis and the angle rotation element 4. When recording video from scene to scene, no subsequent video editing is required.

[0039] In summary, the selfie stick of the present invention offers the following advantages: Since the third bevel gear, which is transmission-connected to the mounting platform, can always remain engaged with the second bevel gear during the rotation of the angle rotating member and the mounting platform, the transmission force of the operating member can always be transmitted to the mounting platform through the three bevel gears, and the operating member can control the mounting platform to rotate around its own axis regardless of the rotation angle of the angle rotating member, thereby expanding the functions of the selfie stick. When shooting video from scene to selfie, the shooting angle of the mounting platform and the shooting equipment on it can be quickly adjusted, and the recorded video does not require editing, which reduces the requirements for the videographer's professional skills.In addition, the control unit can control the mounting platform when the selfie stick is extended and retracted to any length, allowing it to rotate on its own axis.
