Since the plurality of first teeth 143 are equally spaced around the entire circumference of the tooth surface 142, each second tooth 223 can be received in the first tooth slot 144 at any position of the circumference, so that the handle assembly 20 can rotate in a range of 0 ° to 360 ° with respect to the side plate assembly 10 and can be held on the side plate assembly 10. When the plurality of first teeth 143 are equally spaced around the entire circumference of the tooth surface 142, even if there is only one second tooth 223 on the handle assembly 20, the handle assembly 20 can rotate in the range of 0 ° to 360 ° with respect to the side plate assembly 10 and can be held on the side plate assembly 10, and at this time, the first tooth groove 144 is the engaging portion 101 and the second tooth 223 is the engaging portion 201.

Since the plurality of second teeth 223 are equally spaced around the entire circumference of the engaging surface 222, each first tooth 143 can be received in the second tooth groove 224 at any position on the circumference, so that the handle assembly 20 can rotate in a range of 0 ° to 360 ° with respect to the side plate assembly 10 and can be held at different positions on the side plate assembly 10. When the plurality of second teeth 223 are equally spaced around the entire circumference of the engaging surface 222, even if there is only one first tooth 143 on the side plate assembly 10, the handle assembly 20 can rotate in the range of 0 ° to 360 ° with respect to the side plate assembly 10 and can be held at different positions on the side plate assembly 10, in which case, the first tooth 143 is the engaging position 101 and the second tooth groove 224 is the engaging portion 201.

Referring to fig. 4 and 9, the locking member 30 can be used to separate the first connecting member 14 and the second connecting member 22 so that the handle assembly 20 can be rotated relative to the side plate assembly 10. The retaining member 30 can also be used to lock the first connector 14 and the second connector 22 so that the handle assembly 20 can be held in different positions on the side plate assembly 10.

Specifically, the locker 30 includes a connecting rod 31 and a rotating part 32. The rotation portion 32 is disposed at one end of the connection rod 31, and a user can rotate the rotation portion 32 to rotate the connection rod 31. The connecting rod 31 is movably inserted through the handle locking hole 213, the second locking hole 225, the first locking hole 145, and the side plate locking hole 112 in this order to mount the handle assembly 20 to the side plate assembly 10. The rotating portion 32 is accommodated in the first accommodating groove 2112 and located on a side of the connecting portion 212 away from the second end face 2122, and specifically, the rotating portion 32 may be partially accommodated in the first accommodating groove 2112 or completely accommodated in the first accommodating groove 2112. When the locking member 30 locks the first connecting member 14 and the second connecting member 22, the first tooth 143 engages with the second tooth 223 to fix the first connecting member 14 relative to the second connecting member 22, and the rotating portion 32 abuts against the first end face 2121. When the locker 30 separates the first link 14 and the second link 22, the first tooth 143 is separated from the second tooth 223, and at this time, the second link 22 (the handle assembly 20) can be rotated with respect to the first link 14 (the side plate assembly 10).

In the present embodiment, the surface of the tie rod 31 is formed with a male screw, the inner wall of the first locking hole 145 is formed with a female screw, and when the tie rod 31 is inserted into the first locking hole 145, the male screw of the tie rod 31 is screwed with the female screw of the first locking hole 145.

When it is desired to rotate the handle assembly 20 from one position of the side plate assembly 10 to another, the user can rotate (e.g., rotate counterclockwise) the rotating portion 32 to move the rotating portion 32 away from the first connector 14 (i.e., unscrew the retaining member 30). When the rotation portion 32 moves by a distance greater than the tooth height of the first teeth 143 and keeps the connection rod 31 screwed into the first locking hole 145, the connection rod 31 does not slip out of the first locking hole 145, and the user can slide the second link 22 (the handle assembly 20) in the extending direction of the connection rod 31 and separate the second teeth 223 from the first teeth 143. When the second tooth 223 is disengaged from the first tooth 143, the user may rotate the handle assembly 20 to rotate the second link 22 relative to the first link 14. When the handle assembly 20 is rotated to the proper position, the user can slide the second connecting member 22 (the handle assembly 20) along the extending direction of the connecting rod 31 and engage the second teeth 223 with the first teeth 143, and at this time, the user can rotate (e.g., rotate clockwise) the rotating portion 32 to move the rotating portion 32 toward the first connecting member 14 (i.e., tighten the locking member 30) to fix the second connecting member 22 to the first connecting member 14, so that the handle assembly 20 can be maintained at the proper position on the side plate assembly 10.

When the included angle α between the handle assembly 20 and the side plate assembly 10 is 0 °, the handle assembly 20 and the side plate assembly 10 are overlapped, the handle assembly 20 is in a storage and use state, and at this time, the space occupied by the connecting device 100 is small, so that the connecting device 100 is convenient to store and carry.

In the connecting device 100 of the present application, the side plate assembly 10 is detachably mounted on the pan/tilt head 200, so that when a user does not need to use the pan/tilt head 200, the user can detach the connecting device 100 from the pan/tilt head 200, and at this time, the connecting device 100 and the pan/tilt head 200 are more convenient to store and carry; the side plate assembly 10 can rotate relative to the holder 200 and can be maintained at different positions of the holder 200, so that the connecting device 100 and the holder 200 can form a plurality of using modes and/or using postures, and diversification of application scenes is facilitated.
