The second supporting portion 322 is provided with a protruding portion 3220. The operating portion 321 and the second abutting portion 322 are located at two sides of the blocking portion 320. Referring to fig. 3, when the toggle member 32 is assembled to the second housing 20, the toggle member 32 is partially received in the second concave groove 2011 of the second housing 20, and the operation portion 321 passes through the through hole 2030 of the second housing 20 and is exposed from the through hole 2030, so as to facilitate the operation of the operation portion 321. The blocking portion 320 of the toggle member 32 abuts against the sidewall 203 of the second housing 20 to prevent the toggle member 32 from separating from the second housing 20.

Referring to fig. 12, the bearing 22 is located in a space defined by the rotor shaft 204 of the second housing 20 and fixed to the rotor shaft 204, the rotor 111 is sleeved on the periphery of the rotor shaft 204 and fixed to the rotor shaft 204, the rotor 111 is located in the accommodating space 104 of the first housing 10, and the bearing 22 is sleeved on the positioning column 103 of the first housing 10, so that the rotor 111 can drive the rotor shaft 204 to rotate when rotating, and further drive the clamping mechanism 2 to rotate. The fixing member 12 is fixed to the top end of the positioning column 103 and located above the base 201 of the second housing 20, so as to limit the first housing 10 to the second housing 20.

Referring to fig. 13 to 14, the locking member 31 is configured to cooperate with the position-limiting portion 1022, and the toggle member 32 is operable to drive the locking member 31 to move, so that the locking member 31 is in a state of cooperating with the position-limiting portion 1022 or a state of being separated from the position-limiting portion 1022. When the locking mechanism 3 is matched with the limiting part 1022, the clamping mechanism 2 can be locked to prevent the free rotation of the clamping mechanism 2; when the locking mechanism 3 is separated from the limiting part 1022, the clamping mechanism 2 can be unlocked, and the clamping mechanism 2 can rotate freely. In other embodiments, the position-limiting part 1022 may also be disposed on the clamping mechanism 2, and correspondingly, the locking mechanism 3 is disposed on the rotating shaft mechanism 1.

The locking member 31 is partially received in the first concave groove 2010 of the second housing 20, and the press-contact portion 310 of the locking member 31 abuts against the second housing 20 to prevent the locking member 31 from being separated from the second housing 20. The pair of guide posts 2012 of the second housing 20 are respectively fitted into the pair of through holes 3105 of the locking member 31 to guide the up and down movement of the locking member 31. The locking portion 311 of the locking member 31 protrudes from the through hole 2013 of the second housing 20. One end of the elastic element 23 abuts against the cover plate 24, and the other end abuts against the locking element 31. The elastic member 23 is partially received in the receiving groove 3104 of the locking member 31 to ensure that the elastic member 23 does not come off the locking member 31. The locking portion 311 of the locking member 31 cooperates with the position-restricting portion 1022 of the first housing 10 to stop the rotation of the clamping mechanism 2, so as to restrict the clamping mechanism 2 in the locked state. The position limiting part 1022 includes a groove, the locking part 311 moves downward into the groove to lock the clamping mechanism 2, and the locking part 311 moves upward out of the groove to unlock the clamping mechanism 2. After the second abutting portion 322 is separated from the first abutting portion 3101, if the locking portion 311 is located between two adjacent grooves, the rotation of the clamping mechanism 2 can drive the locking portion 311 to move to the upper side of the groove and fall into the groove.

Referring to fig. 15 and 16, when unlocking, the operating portion 321 of the toggle member 32 is pushed, and the second abutting portion 322 of the toggle member 32 moves along the inclined portion 3102 of the locking member 31 to a position below the first abutting portion 3101 of the locking member 31 to support the first abutting portion 3101, so that the locking portion 311 is in the first position disengaged from the position-limiting portion 1022; in the process, the locking member 31 moves upward to disengage from the position-limiting portion 1022 and compress the elastic member 23, and the clamping mechanism 2 can rotate freely. When the clamping mechanism 2 is in the unlocked state, the protruding portion 3220 of the toggle member 32 is accommodated in the first recess 31010 of the first abutting portion 3101, so that the toggle member 32 is prevented from moving when being subjected to an external force, and the clamping mechanism 2 is prevented from being switched to the locked state.

When the clamping mechanism 2 needs to be in the locked state, the operating portion 321 of the toggle member 32 is pushed, the protruding portion 3220 of the toggle member 32 moves out of the first recess 31010 of the first abutting portion 3101, the second abutting portion 322 of the toggle member 32 moves along the inclined portion 3102 of the locking member 32, the second abutting portion 322 is disengaged from the first abutting portion 3101 of the locking member 32, and the locking member 32 moves downward under the action of gravity and the abutting force of the elastic member 23, so that the locking portion 311 moves from the first position to the second position matched with the limiting portion 1022, and the clamping mechanism 2 is prevented from rotating. When the clamping mechanism 2 is in the locked state, the protrusion 3230 of the toggle member 32 is accommodated in the second recess 3103 of the locking member 32, so that the toggle member 32 is prevented from moving when being subjected to an unexpected external force, and the clamping mechanism 2 is prevented from being converted to the unlocked state.

The protrusion 3220 may also be disposed on the locking member 31, and accordingly, the first and

second recesses

31010 and 3103 are disposed on the toggle member 32. In the process of rotating the clamping mechanism 2, the second abutting portion 205 of the second housing 20 moves along the track groove 1020 of the first housing 10, when the second abutting portion 205 abuts against the first abutting portion 1021 of the first housing 10, the clamping mechanism 2 stops rotating continuously, and the clamping mechanism 2 can rotate continuously in the opposite direction, so as to prevent the clamping mechanism 2 from rotating excessively.

According to the handheld tripod head, the clamping mechanism 2 can be switched between the locking state and the unlocking state through the locking mechanism 3, and the clamping mechanism 2 cannot rotate in the locking state, so that the assembly of the fixing piece 8 or the shooting device is facilitated, and the convenience in installation is improved; because the clamping mechanism 2 can not rotate, when the fixing piece 8 or the shooting device is assembled, the rotating shaft mechanism 1 can be held, compared with the method of only holding the clamping mechanism 2, the area for holding is increased, the clamping is convenient, and the convenience for assembling is increased; meanwhile, the holder shaft arm 105 can be held, and the holder shaft arm 105 is longer, so that the holder is more convenient to hold, and the convenience in installation is further improved.

The foregoing detailed description of the apparatus provided in the embodiments of the present invention has been presented for the purpose of illustrating the principles and implementations of the present invention by way of specific examples and is provided for the purpose of facilitating understanding of the principles and concepts of the present invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present invention.
