Preferably, the threaded interface 131 may be configured as an 1/4 threaded hole, and the motion camera interface 133 is configured to include a quick release 1/4 threaded hole.

Alternatively, as shown in fig. 1(a) to 2(g), the expansion seat 11 is provided with a first connecting portion 112, one end of the expansion piece 12 provided with the sliding block 121 is provided with a second connecting portion 123, and the second connecting portion 123 is configured such that when the second sliding portion 122 moves to a predetermined position relative to the first sliding portion 111, the second connecting portion 123 is coaxially aligned with the first connecting portion 112 to form a communication opening. The expansion device 1 further comprises a locking mechanism 14 connected to the communication opening, the locking mechanism 14 being configured to comprise a locking member 141 which places the expansion piece 12 in position relative to the expansion seat 11 in a form-fitting manner in a locked position and which makes the expansion piece 12 movable relative to the expansion seat 11 in an unlocked position, so as to enable switching between the locked state and the unlocked state of the expansion piece 12 and the expansion seat 11.

Exemplarily, as shown in fig. 1(a) and 1(b), the first connection portion 112 is configured as a connection groove at the bottom side of the extended seat 11, and the second connection portion 123 is configured as a connection hole extending perpendicular to the virtual mirror plane at the first end of the extended piece 12. The coupling hole is configured such that when the second slider 122 advances to a predetermined position along the first slider 111, the coupling hole is substantially coaxially aligned with the coupling groove to form a coupling opening such that the head portion of the locking member 141 is held in the coupling opening after passing through and being screwed to the coupling hole. The predetermined position is preferably the end that the second runner 122 can reach to slide on the first runner 111 to improve the ease with which the attachment hole is positioned in coaxial alignment with the attachment recess. Preferably, the locking member 141 may be configured as a thumb screw including a thumb portion 1411, a stopper portion 1412, a receiving portion 1413 and a threaded portion 1414, the connecting hole is further configured as a quick-release threaded hole threadedly fitted with the threaded portion 1414, the connecting groove is configured as a circular groove, and the communicating opening is configured as a circular opening, when the thumb screw passes through the quick-release threaded hole, the knob thumb screw passes the threaded portion 1414 through the threaded quick-release threaded hole and the head portion thereof enters the circular groove until reaching a locking position to limit the movement of the expansion member 12 relative to the expansion seat 11 in the direction of the first sliding portion 111, thereby achieving the locking between the expansion member 12 and the expansion seat 11. The reverse knob hand screws may then effect unlocking between the expansion piece 12 and the expansion seat 11.

More specifically, the threaded portion 1414 of the thumb screw can extend slightly beyond the quick release threaded bore of the extension 12 and can also pass completely through the quick release threaded bore of the extension 12 when the thumb screw is threaded by the knob through the quick release threaded bore until it abuts the extension 11 to the locked position. The threaded portion 1414 of the hand screw is partially or completely retained in the circular groove, the accommodating portion 1413 is accommodated in the quick-release threaded hole, and the size of the limiting portion 1412 is larger than that of the quick-release threaded hole to play a limiting role. Wherein, the hand screw can be 1/4 hand screw, and the screw hole can be quick detach 1/4 screw hole.

Illustratively, as shown in fig. 2(a) to 2(c), the first connecting portion 112 is configured to expand a connecting hole on a sidewall of the seat 11, and the second connecting portion 123 is configured to be a connecting groove on a sidewall of the expanding member 12 that is in contact with the sidewall where the connecting hole is located when the second runner 122 is slidably fitted with the first runner 111. When the second slider 122 is moved to a predetermined position with respect to the first slider 111, the coupling hole is coaxially aligned with the coupling groove to form a coupling opening, and the locking member 141 extends into the coupling groove through the coupling hole. Wherein, in fig. 2(a) and 2(b), the connection hole is provided at the bottom side of the expansion seat 11, a screw thread may be provided at the inner side of the connection hole and/or the connection groove, and the locking member 141 is configured as a thumb screw to cooperate with each other to achieve locking and unlocking between the expansion seat 11 and the expansion member 12. However, as shown in fig. 2(c) in which the coupling hole is provided at the left side of the expanding seat 11, a screw thread may be provided on the coupling groove to cooperate with the locking piece 141 configured as a thumb screw.

Optionally, the locking mechanism 14 further includes a retainer 142 configured to retain the locking member 141 in the locked position by wedging or biasing.

Illustratively, as shown in fig. 2(d) and 2(e), the holder 142 is configured to include a first operating handle 1421 slidably disposed on the expanding seat 11 and provided with a wedge block 1422 at one end, and the locking member 141 is configured to be slidably disposed on the first operating handle 1421 and received in an abutment block of the communication opening. The abutment block is configured to be clamped between the second connection 123 and the wedge block 1422 when the first operating handle 1421 is moved to a predetermined position relative to the extension 11 and the abutment block, so as to lock the extension 11 with the extension 12. The contact surface of the abutting block and the first operating handle 1421 is fitted to the wedge surface of the wedge block 1422, and the first operating handle 1421 moves along the extending direction of the first sliding portion 111, so that the abutting block is not allowed to move radially relative to the communication opening, but can move axially relative to the communication opening along with the position of the abutting block 1422 until the abutting second connecting portion 123 reaches the locking position, and the expansion member 12 and the expansion seat 11 are locked.

Preferably, the first operating handle 1421 is connected to the expanding seat 11 through a first elastic member 1423, such as a spring, before the expanding member 12 is inserted into the expanding seat 11, the first operating handle 1421 is pushed into the expanding seat 11 to compress the spring, so that the abutting block moves downward to smoothly move the second sliding portion 122 to a predetermined position to form a communication opening with the first sliding portion 111. The first operating handle 1421 is then released to return to its initial position, and the outward spring force provided by the spring force ensures that the abutment block does not move down to loosen the extension 12 and the expansion seat 11. When the expanding seat 11 and the expanding member 12 need to be unlocked, the first operating handle 1421 is pushed into the expanding seat 11 again. The locking condition of this preferred design is more stable than if the locking condition were ensured solely by the friction between the wedge block 1422 and the abutment block.

Exemplarily, as shown in fig. 2(f) and 2(g), the first connection part 112 is configured as a connection groove, and the second connection part 123 is configured as a connection hole. The holder 142 is configured to include a second operating handle 1424 slidably disposed on the expansion member 12, and the locking member 141 is configured as a top bead located in the connecting hole, the top bead being configured to be caught between the second operating handle 1424 and the first connecting portion 112 in a section of the communication opening adjacent to the first connecting portion 112 when the second operating handle 1424 is moved to a predetermined position with respect to the expansion member 12, so that the expansion seat 11 is locked with the expansion member 12. Wherein, the end of the second connecting portion 123 is formed with a closed arc surface to prevent the top bead inside from falling. In addition, the end side of the second operating handle 1424 adjacent to the tip bead is provided with a slope to save labor when the second operating handle 1424 is operated to change the expanding seat 11 and the expanding member 12 from the locked state to the unlocked state.

Preferably, the second operating handle 1424 is connected to the expanding member 12 through a second elastic member 1425 such as a spring, and before the expanding member 12 is inserted into the expanding seat 11, the second operating handle 1424 is operated to compress the spring, so that the top ball is loosened to smoothly move the second sliding part 122 to the predetermined position to form a communication opening with the first sliding part 111. The second operating handle 1424 is then released to return to its original position, and the spring force provides a spring force to ensure that the top bead is clamped between the second operating handle 1424 and the first connector 112. When it is necessary to unlock the expanding seat 11 and the expanding member 12, the second operating handle 1424 is operated to compress the spring again. The locked state of this preferred design is more stable than if the locked state were ensured only by the friction between the second operating handle 1424 and the top bead.

Alternatively, as shown in fig. 3, the stabilizer 2 is used to mount a photographing device 3 such as a camera to adjust the posture of the photographing device 3. Herein, a side adjacent to the camera 3 is referred to as a near side, and a side distant from the camera 3 is referred to as a far side.
