The central second bevel gear is fixed axially but rotatably mounted on the outer periphery of the rotary element. The third bevel gear, which is transmission-connected to the mounting platform, remains meshed with the second bevel gear when rotating together with the rotary element and the mounting platform. Therefore, the operating force of the operating element can be constantly transmitted to the mounting platform via the three bevel gears. Regardless of the angle of the rotary element, the operating element can control the mounting platform to rotate around its own axis, enhancing the functionality of the selfie stick. When shooting video from one scene to another, the shooting angle of the mounting platform and the filming equipment mounted thereon can be quickly adjusted, and the captured video does not require editing, reducing the need for professional skills on the part of the photographer. 2. The selfie stick provided by this invention has an operating member connected to the outer tube, and a transmission rod assembly coaxially arranged inside the outer tube. When the outer tube is relatively thin and can be held with one hand to take a photo, the operating member on the outer tube can be operated with a finger, and the operating member can move the mounting platform and the photographic device thereon via the transmission rod assembly to rotate. When the outer tube is relatively thick and needs to be held with both hands to take a photo, the mounting platform and the photographic device thereon can be rotated by holding the outer tube with one hand and operating the operating member with the other hand. The overall structure is compact and easy to operate. 3. In the selfie stick provided by the present invention, the outer tube assembly is a telescopic tube assembly, the transmission rod assembly is a telescopic rod assembly, and the telescopic rod assembly can extend and retract synchronously with the telescopic tube assembly, which is the basis for realizing the telescopic adjustment of the selfie stick.

[0026] Furthermore, the technical features of different embodiments of the present invention described below can be combined with each other as long as they do not contradict each other.

[0027] The selfie stick shown in FIGS. 1 and 2 includes a support mechanism, a connecting base 3, an angle rotation member 4, an angle rotation shaft 5, a mounting platform 7, and a transmission mechanism. In some embodiments, the support mechanism includes an outer tube 1 and an outer tube assembly 2 coaxially mounted inside the outer tube 1, with one end of the outer tube assembly 2 connected to the outer tube 1, the connecting base 3 fixedly connected to the other end of the outer tube assembly 2, and an operating member 6 connected to one end of the outer tube 1. The angle rotation member 4 is rotatably connected to the connecting base 3 around the axis of the angle rotation shaft 5, the axial direction of which is perpendicular to the axial direction of the support mechanism. The mounting platform 7 is connected to one side of the angle rotation member 4 opposite the connecting base 3, and is rotatable together with the angle rotation member 4 around the axis of the angle rotation shaft 5. The mounting platform 7 is used to mount photographic equipment. The transmission mechanism is power-transmittingly connected between the operating member 6 and the mounting platform 7. In an alternative embodiment, the outer tube assembly 2 can be omitted, and the support mechanism can include only a single, longitudinally extending outer tube 1, in which case the connecting seat 3 is directly fixed to one axial end of the outer tube 1. With this type of selfie stick, when the outer tube 1 is relatively thin and can be held with one hand to take a photo, the operating member 6 on the outer tube 1 can be operated with a finger, and the operating member 6 moves the mounting platform 7 and the photographic equipment thereon to rotate via a transmission mechanism; when the outer tube 1 is relatively thin and needs to be held with both hands to take a photo, the outer tube 1 can be held with one hand and the operating member 6 can be operated with the other hand to rotate the mounting platform 7 and the photographic equipment thereon, resulting in a compact overall structure and easy operation.

[0028] In some embodiments, the transmission mechanism includes a first bevel gear 81, a second bevel gear 82, and a third bevel gear 83 that are sequentially meshed and transmission-connected, and a transmission rod assembly 84 that is coaxially arranged inside the outer tube assembly 2. One end of the transmission rod assembly 84 is transmission-connected to the operating member 6, and the other end of the transmission rod assembly 84 is fixedly connected to the first bevel gear 81, and the transmission rod assembly 84 is arranged coaxially with the first bevel gear 81, so that when the operating member 6 is operated, the first bevel gear 81 can be moved to rotate about its own axis relative to the connecting seat 3 via the transmission rod assembly 84. The second bevel gear 82 is fixed in the axial direction and fitted around the outer periphery of the angular rotation shaft 5 so as to be rotatable in the circumferential direction, and the axial direction of the second bevel gear 82 is perpendicular to the axial direction of the first bevel gear 81. The third bevel gear 83 is connected to the mounting platform 7 so as to be fixed in the axial direction and rotatable in the circumferential direction, and when the operating member 6 is operated, the mounting platform 7 can be moved to rotate about its own axis by sequential transmission action between the transmission rod assembly 84, the first bevel gear 81, the second bevel gear 82, and the third bevel gear 83. In some alternative embodiments, the transmission rod assembly 84 inside the outer tube assembly 2 can be omitted, and the operating member 6 can directly move the first bevel gear 81 to rotate about its own axis, or can indirectly move the first bevel gear 81 to rotate about its own axis via another transmission member located outside the outer tube 1.

[0029] In this selfie stick, when the angle rotation member 4 is rotated to a desired angle, the transmission mechanism between the operating member 6 and the mounting platform 7 includes three bevel gears that mesh sequentially. The first bevel gear 81 rotates around its own axis when the operating member 6 is operated. The central second bevel gear 82 is fixed axially but rotatably mounted on the outer periphery of the angle rotation shaft 5. The third bevel gear 83, which is transmission-connected to the mounting platform 7, is always engaged with the second bevel gear 82 when rotating together with the angle rotation member 4 and the entire mounting platform 7. This allows the transmission force of the operating member 6 to be constantly transmitted to the mounting platform 7 via the three bevel gears. Regardless of the angle to which the angle rotation member 4 is rotated, the operating member 6 can control the mounting platform 7 to rotate around its own axis, enhancing the functionality of the selfie stick. When shooting video from one scene to another, the shooting angle of the mounting platform 7 and the filming equipment mounted thereon can be quickly adjusted, and the captured video does not require editing, reducing the need for specialized skills on the part of the photographer.

[0030] 1 and 2 , in some embodiments, the outer tube assembly 2 is a telescopic tube assembly, and a telescopic end of the telescopic tube assembly is fixedly connected to the connecting seat 3. The telescopic tube assembly includes multiple stages of telescopic tubes fitted sequentially from the outside to the inside, and the multiple stages of telescopic tubes are fixed in the circumferential direction and slidable in the axial direction, with one end of the telescopic tube located in the outermost stage fixedly connected to the outer tube 1 and the telescopic end of the telescopic tube located in the innermost stage fixedly connected to the connecting seat 3. The transmission rod assembly 84 is a telescopic rod assembly, and the telescopic rod assembly can extend and retract in sync with the telescopic tube assembly, and the telescopic end of the telescopic rod assembly is fixedly connected to the first bevel gear 81. The telescopic rod assembly includes multiple stages of transmission rods fitted sequentially from the inside to the outside, and the multiple stages of transmission rods are fixed in the circumferential direction and slidable in the axial direction, with one end of the transmission rod of the innermost stage being power-transmittingly connected to the operating member 6 and the telescopic end of the transmission rod of the outermost stage being fixedly connected to the first bevel gear 81. In this selfie stick, the telescopic rod assembly can extend and retract in sync with the telescopic tube assembly, so that when the selfie stick is at any length, the operating member 6 can control the mounting platform 7 to rotate around its own axis, thereby enhancing the functionality of the selfie stick.

[0031] As shown in FIGS. 2 and 3 , in some embodiments, the operating member 6 is a knob connected to one end of the outer tube 1. A ring gear is provided on the inner wall of the knob. A central gear 85 is fixedly connected to one end of a transmission rod assembly 84. The transmission mechanism further includes three planetary gears 86, the gears of which are meshed between the ring gear and the central gear 85 for transmission connection. An end cap 11 is fixedly connected to one axial end of the outer tube 1 and is provided to cover the three planetary gears 86 and the central gear 85. By rotating the operating member 6, the operating member 6 rotates the transmission rod assembly 84 of the central gear 85 located at the center via the planetary gear structure. This transmission method has high transmission stability. In alternative embodiments, the operating member 6 may be provided at any position outside the outer tube 1. The operating member 6 may be operated in any manner, such as a dial button for left-right toggle operation, a dial button for up-down toggle operation, or a key for pressing. The operating member 6 may be operated in any manner.

[0032] 2 and 4 , in some embodiments, the connecting base 3 is generally U-shaped and includes a bottom plate 31 and a pair of opposite ear plates 32 connected to both ends of the bottom plate 31. The bottom plate 31 is fixedly connected to the outer tube assembly 2. An opening is formed in the bottom plate 31, and one end of the transmission rod assembly 84 passes through the opening in the bottom plate 31. A first bevel gear 81 is fixed to the end of the transmission rod assembly 84 that passes through the bottom plate 31, and the first bevel gear 81 is located between the pair of ear plates 32. The angular rotation shaft 5 is fixedly connected between the pair of ear plates 32, and the angular rotation member 4 is rotatably connected to the angular rotation shaft 5 with a damping force. The manner in which the angular rotation member 4 is rotatably connected to the angular rotation shaft 5 with a damping force facilitates arbitrary adjustment of the angle of the angular rotation member 4 and the mounting platform 7 thereon, and facilitates adjustment of the pitch angle of the imaging device on the mounting platform 7.

[0033] 2, 4, and 5, in some embodiments, the mounting platform 7 is located at one end of the angular rotation member 4 away from the connecting seat 3, and a positioning hole 7a is provided on one side of the mounting platform 7 facing the angular rotation member 4. A platform connecting pillar 71 is fixedly connected to one end of the mounting platform 7 facing the third bevel gear 83, and a connecting shaft assembly 72 is connected between the central hole of the third bevel gear 83 and the central hole of the platform connecting pillar 71, and the connecting shaft assembly 72 is used to secure the third bevel gear 83 and the platform connecting pillar 71 in the axial direction. The angular rotation member 4 includes a top plate that is flush with the mounting platform 7, and the top plate is provided with a central through-hole that passes through both ends and a mounting through-hole 4a, with the mounting through-hole 4a offset from the center of the top plate. The locking pin assembly 9 in the mounting through-hole 4a extends in the same direction as the connection between the angular rotation member 4 and the mounting platform 7. One end of the locking pin assembly 9 can protrude from the top surface 4b of the tabletop, and the other end can protrude from the inner surface of the tabletop. The locking pin assembly 9 can be inserted into the positioning hole 7a by the biasing force of the third bevel gear 83, restricting the mounting platform 7 from rotating around its own axis, in a locked state, or protruded out of the positioning hole 7a, allowing the mounting platform 7 to rotate around its own axis, in an unlocked state. When the third bevel gear 83 rotates around its own axis, the locking pin assembly 9 can be inserted into the positioning hole 7a under the action of the third bevel gear 83, restricting the rotation of the mounting platform 7 and fixing it at a set angular position. When the locking pin assembly 9 protrudes out of the positioning hole 7a, the third bevel gear 83 can move the mounting platform 7 to rotate, allowing the mounting platform 7 to adjust its shooting direction.

[0034] 2, 4 and 6, in some embodiments, the third bevel gear 83 includes a gear plate body 831, a bevel tooth portion 832, and a transmission portion having an integral structure, the bevel tooth portion 832 and the transmission portion being located on opposite sides of the gear plate body 831, the bevel tooth portion 832 of the third bevel gear 83 meshing with the third bevel gear 83, and the transmission portion engaging with the platform connecting post 71. One side of the gear plate body 831 facing the mounting platform 7 includes a protrusion 831a and a recess 831b located on the same circumference of the gear plate body 831, and the distance between the recess 831b and the mounting platform 7 is greater than the distance between the protrusion 831a and the mounting platform 7. When the protrusion 831a of the gear plate body 831 is located at one end of the stop pin assembly 9, the protrusion 831a presses one end of the stop pin assembly 9 to insert the other end of the stop pin assembly 9 into the positioning hole 7a. When the recess 831b of the third bevel gear 83 is located at one end of the stop pin assembly 9, one end of the stop pin assembly 9 is inserted into the recess 831b, and the other end of the stop pin assembly 9 is retracted outside the positioning hole 7a. An inclined transition portion 831c is provided at the position where the protrusion 831a and the recess 831b meet.

[0035] 4, 6, and 7, in some embodiments, a pair of transmission bumps 833 are integrally formed on the outer periphery of the transmission part, and a pair of driven bumps 711 are provided on one side of the platform connecting post 71 facing the transmission part, spaced apart and located on the same circumference, where the pair of driven bumps 711 and the transmission bumps 833 are located on the same circumference. When the transmission bumps 833 rotate to a position where they abut against the driven bumps 711, the transmission bumps 833 cause the driven bumps 711 to rotate synchronously, so that the platform connecting post 71 and the mounting platform 7 rotate about their own axes; when the transmission bumps 833 rotate between the pair of driven bumps 711, the driven bumps 711 do not rotate synchronously with the transmission bumps 833. As will be understood, the number and positions of the transmission bumps 833 and the driven bumps 711 can be adaptively selected according to the required rotation angle. When the positions of the stop pin assembly 9 and the recessed portion 831b of the third bevel gear 83 correspond to each other, the third bevel gear 83 can move the driven bump 711 to rotate synchronously via the transmission bump 833 when it rotates, and when the positions of the stop pin assembly 9 and the protruding portion 831a of the third bevel gear 83 correspond to each other, the third bevel gear 83 does not move the driven bump 711 to rotate synchronously when it rotates.

[0036] 2, 6 and 8, a stopper pin release spring 10 is provided in the mounting through-hole 4a. The stopper pin assembly 9 includes a stopper pin fixing seat 91 provided in the mounting through-hole 4a and a stopper pin 92 connected to the stopper pin fixing seat 91, one end of the stopper pin 92 can be inserted into the positioning hole 7a, and the stopper pin release spring 10 is elastically provided between the stopper pin fixing seat 91 and the angular rotation member 4. The elastic force of the stopper pin release spring 10 is suitable for driving the stopper pin fixing seat 91 to move in a direction away from the mounting platform 7, thereby causing the stopper pin 92 to protrude out of the positioning hole 7a. The locking pin assembly 9 further includes a locking pin stopper seat 93 and a locking pin spring 94. The locking pin stopper seat 93 is movably fitted onto the outer periphery of the locking pin fixing seat 91 along the axial direction of the locking pin assembly 9. A hemispherical stopper protrusion 931 is provided on one end of the locking pin stopper seat 93 facing away from the locking pin 92, and the locking pin spring 94 is elastically provided between the locking pin stopper seat 93 and the locking pin 92. The elastic force of the locking pin spring 94 is suitable for driving the locking pin stopper seat 93 to move in a direction approaching the third bevel gear 83, whereby the stopper protrusion 931 comes into contact with the protrusion 831a or recess 831b of the third bevel gear 83.

[0037] When the operating member 6 is operated, the operating member 6 moves the transmission rod assembly 84 to rotate, and via the transmission rod assembly 84, the first bevel gear 81 moves to rotate around its own axis, the second bevel gear 82 rotates following the first bevel gear 81, and the third bevel gear 83 rotates following the second bevel gear 82. When the third bevel gear 83 initially rotates, the transmission bump 833 disposed on the third bevel gear 83 rotates from the first side wall 711a of one driven bump 711 to the second side wall 711b of the other driven bump 711 (or from the second side wall 711b of one driven bump 711 to the first side wall 711a of the other driven bump 711), and then the transmission bump 833 abuts against the driven bump 711. At the same time, the contact position between the stop pin assembly 9 and the third bevel gear 83 moves from the convex portion 831a to the concave portion 831b. At this time, the stop pin assembly 9 moves from the mounting platform 7 to the concave portion 831b. After being released and fixed to the platform connecting post 71, the mounting platform 7 can rotate following the third bevel gear 83. When the third bevel gear 83 rotates to a certain angle, the stop pin assembly 9 moves to the protrusion 831a again, and the stop pin assembly 9 hits the positioning hole 7a located on the mounting platform 7. One end of the stop pin assembly 9 is inserted into the positioning hole 7a again to fix the mounting platform 7 at the set rotation angle. By operating the operating member 6 in the reverse direction, the platform of the mounting platform 7 can return to its original angle along the same path. The rotation angle is set during design, which in this embodiment is 180 degrees.

[0038] The specific operation of such a selfie stick is as follows: the operator mounts the photographic device on the mounting platform 7, extends the outer tube assembly 2 to an appropriate length, rotates the angle rotation member 4, rotates the photographic device to the required shooting angle, holds the outer tube 1 with his hand, and operates the operating member 6 to control the mounting platform 7 to rotate along the mounting axis of itself and the angle rotation member 4, so that the video can be shot from scene to selfie without the need for post-editing.

[0039] As described above, the selfie stick provided by the embodiment of the present invention has the following advantages: The third bevel gear, which is transmission-connected to the mounting platform, can always remain engaged with the second bevel gear when rotating together with the angle rotation member and the entire mounting platform. Therefore, the transmission force of the operating member can always be transmitted to the mounting platform via the three bevel gears. Regardless of the angle of rotation of the angle rotation member, the operating member can control the mounting platform to rotate around its own axis, thereby enhancing the functionality of the selfie stick. When shooting video from one scene to another, the shooting angle of the mounting platform and the camera mounted thereon can be quickly adjusted, and the captured video does not require editing, reducing the need for professional skills on the part of the photographer. Furthermore, when the selfie stick is extended or retracted to any desired length, both operating members can control the mounting platform to rotate around its own axis.
