[0046] Optionally, the reset member 120 is provided according to actual needs. In this embodiment, the reset member 120 is a spring and two reset members 120 are provided. The inner wall of the installation cavity 103 is formed with a mounting groove 104 for mounting the reset member 120. One end of the reset member 120 abuts against the mounting groove 104, and the other end of the reset member 120 abuts against the end surface of the insertion portion 111 on the control member 110 extending toward the installation cavity 103.

[0047] Optionally, the two reset members 120 are respectively sleeved with the guide posts 132 between the two wedging blocks 130, so that they are located between the two wedging blocks 130, so that the two ends of the reset member 120 are respectively abutted against the guide posts 132 of one wedging block 130, and the reset and expansion of the reset member 120 can drive the two wedging blocks 130 to expand, so that the exposed parts of the wedging blocks 130 are in contact with the self-locking inclined surface 202 and the clamping inclined surface 102 to wedge and tighten, so as to produce a locked state for the structural member 200, and conversely, the two wedging blocks 130 can be driven by the compression of the reset member 120.

[0048] In some embodiments, a pressure plate 105 is connected to the fitting groove 101 of the connecting seat 100, and an avoidance groove 106 for matching the wedge block 130 is opened on the pressure plate 105. The pressure plate 105 is installed on the bottom of the fitting groove 101 by screws, and guide slopes are formed on opposite sides of the pressure plate 105. When the pressure plate 105 is installed on the fitting groove 101, a self-locking channel is formed between the guide slope and the clamping slope 102, and the wedge block 130 is located between the clamping slope 102 and the guide slope of the fitting groove 101.

[0049] In some embodiments, the structural member 200 can slide relative to the fitting groove 101 of the connecting seat 100 through the sliding portion 201. When the control member 110 is in a locked state, the fitting portion weds and presses the structural member 200 through the wedging block 130. When the control member 110 is in an unlocked state, the fitting portion releases the structural member 200 through the wedging block 130.

[0051] In this embodiment, the sliding structure is composed of an insertion groove 112 recessed on the insertion part 111, and a latch 131 is provided on the wedge block 130. The insertion groove 112 of the insertion part 111 is inserted with the latch 131 on the wedge block 130. The insertion part 111 extends into the installation cavity 103, which can drive the latch 131 on the wedge block 130 to slide along the insertion groove 112 of the insertion part 111. The sliding direction of the latch 131 is set at an angle to the sliding direction of the insertion part 111 in the control member 110. Due to the pairing of the insertion groove 112 formed on the insertion part 111 and the latch 131, when the control member 110 is pressed or released, the insertion groove 112 can drive the wedge block 130 to unlock or lock the self-locking inclined surface 202 of the structural member 200.

[0052] When the control member 110 is pressed by an external force, the insertion portion 111 of the control member 110 slides along the installation cavity 103, and the position of the insertion slot 112 changes accordingly, so that the pin 131 inserted in the insertion slot 112 is pushed by the side wall of the insertion slot 112 and slides along the path of the insertion slot 112, thereby driving the wedge block 130 to move.

[0053] In some embodiments, the insertion portion 111 and the control member 110 are integrally formed, and a relative insertion groove 112 is set on the insertion portion 111 of the control member 110. The pins 131 on the wedge block 130 are set corresponding to the insertion grooves 112 on the insertion portion 111, and each pin 131 is correspondingly plugged into an insertion groove 112, which is set according to actual conditions, wherein the number of groups of insertion grooves 112 and pins 131 can be set to one group or more groups according to actual conditions.

[0054] In this embodiment, the connection seat 100 forms a wedge-tight fit with the two self-locking inclined surfaces 202 on the structural member 200 through the two wedge-tightening blocks 130, which can improve the connection stability and operability between the two, thereby further improving the connection tightness between the two components of the photographic equipment. In addition, as other embodiments, optionally, in the case where a structure is provided at the slot end of the connection seat 100 close to the sleeve slot 101 to prevent the structural member 200 from sliding out, only one wedge-tightening block 130 can be provided at the corresponding other end to wedge between the clamping inclined surface 102 of the connection seat 100 and the self-locking inclined surface 202 of the sliding portion 201 to form self-locking.

[0055] Specific use in this embodiment: The combined use of the control member 110, the reset member 120 and the wedge block 130 allows the connection state of the connection seat 100 and the structural member 200 to be flexibly switched. In the unlocked state, by squeezing or pressing the end of the control member 110 exposed on the outer side of the connection seat, the two wedge blocks 130 are clamped and slid loose from the clamping inclined surface 102 of the connection seat 100 and the self-locking inclined surface 202 of the sliding part 201. The reset member 120 is compressed under squeezing, so that the structural member 200 can be easily removed from the connection seat. 100, and in the locked state, release the control member 110, so that the reset member 120 is reset and expanded to form an extrusion effect, so that the two wedge blocks 130 are tightly wedged between the clamping slope 102 of the connecting seat 100 and the self-locking slope 202 of the sliding part 201, ensuring the firmness and stability of the connection, and not easily loosened or falling off due to external force, thereby improving the durability and reliability of the component, improving the efficiency and user experience of the connection of the photographic device, and can be adapted to other equipment and scenes that require quick connection and disassembly.
