[0042] In a specific embodiment, a control member 8 is further included, which is connected to the locking pin 6 and is used to control the locking pin 6 to reciprocate along the second direction b, so as to switch the locking pin 6 and the locking socket 7 between a locked state and an unlocked state.

[0043] In this embodiment, through the control member 8, the user can easily switch the locking state and unlocking state of the locking pin 6 and the locking hole 7, so as to conveniently connect or disconnect the sub-button 1 and the mother buckle 2. The function of the control member 8 is to release the locking pin 6 when necessary, so that the pin can move freely in the second direction b, so as to strengthen the snap connection between the sub-button 1 and the mother buckle 2. This design not only improves the operability of the dovetail buckle, ensures the safety and stability of the dovetail buckle during use, but also enhances its flexibility and convenience in use.

[0044] In a specific embodiment, the connecting member 5 includes a first connecting member 51 and a second connecting member 52 , wherein the first connecting member 51 is located on the sub-buckle 1 , and the second connecting member 52 is located on the female buckle 2 .

[0045] In this embodiment, the first connecting member 51 is tightly embedded in the sub-button 1, and the second connecting member 52 is tightly embedded in the female buckle 2, and the sub-button 1 and the female buckle 2 can be connected to the external device through the first connecting member 51 and the second connecting member 52 respectively. This design ensures the firmness and stability of the connecting member 5, so that the dovetail buckle can be firmly connected to the external device. Through the cooperation of the first connecting member 51 and the second connecting member 52, the dovetail buckle can maintain a stable connection state during use, and also provides convenient disassembly and installation operations, enhancing its convenience and flexibility in use.

[0046] In a specific embodiment, a first hollow portion 9 is also provided on one side of the sub-button 1 on which the first connecting member 51 is provided, and a second hollow portion 10 is also provided on one side of the female button 2 on which the second connecting member 52 is provided.

[0047] In this embodiment, the design of the first hollow portion 9 and the second hollow portion 10 not only helps to reduce the weight of the sub-button 1 and the mother buckle 2, but also can improve the overall lightness and ease of use of the dovetail buckle without affecting the structural stability. By providing the hollow portions on the sub-button 1 and the mother buckle 2, the amount of material used can be effectively reduced, while also reducing the load on the connector and extending the service life of the dovetail buckle. This design not only takes into account the functional requirements of the dovetail buckle, but also focuses on its comfort and convenience in practical applications.

[0048] In a specific embodiment, the connecting member 5 is a threaded structural member, and the sub-buckle 1 and the female buckle 2 are respectively provided with openings 11 matching the threaded structural member, and the sub-buckle 1 and the female buckle 2 are respectively connected to the head and the rod of the threaded structural member through the openings 11.

[0049] In this embodiment, the connector 5 is designed with a threaded structure, and the sub-button 1 and the mother buckle 2 are respectively provided with openings 11 that match the threaded structure. These openings 11 are precisely designed to accommodate the head and the rod of the threaded structure, so as to achieve a firm connection between the sub-button 1 and the mother buckle 2 and the connector 5 passing through them. The threaded structure (here is a screw) allows it to pass through the corresponding fastener by screwing into the part with the internal thread in the opening 11, so that the middle part with a smaller diameter in the threaded structure is accommodated in the through hole of the opening 11, ensuring that the connector will not be separated from the fastener and is safely and stably connected to the external device. The design of this threaded structure is not only simple and effective, but also easy to install and disassemble, allowing users to quickly and conveniently adjust or replace the connector to adapt to different usage needs and scenarios.

[0050] In a specific embodiment, the sub-buckle 1 and the female buckle 2 are provided with a dovetail slot 3 and a dovetail plug 4, and one side thereof is respectively provided with an inner recess 12 matching the head of the threaded structural member.

[0051] In this embodiment, the sub-buckle 1 and the mother buckle 2 are respectively provided with a dovetail slot 3 and a dovetail plug 4, and a concave portion 12 that matches the head of the threaded structure is further added. Such a sophisticated design not only makes the connection between the two fasteners more secure, but also provides greater convenience during the installation process. The addition of the concave portion 12 allows the head of the threaded structure to be accurately embedded therein, while maintaining the stability and safety of the connection without affecting the snap connection between the dovetail slot 3 and the dovetail plug 4. This ingenious design not only takes into account the functional requirements of the connection, but also pays attention to the beauty and practicality of the overall structure, providing a more complete solution for the application of dovetail buckles.

[0052] In a specific embodiment, both the sub-clasp 1 and the female buckle 2 are provided with a protective portion 13 for protecting an external device.

[0053] In this embodiment, further, as shown in the attached Figure 4 and attached Figure 5 As shown, both the sub-button 1 and the mother buckle 2 are provided with a protective portion 13 for protecting the external device. These protective portions 13 are intended to provide additional protection for the external device to prevent it from being damaged or interfered with by external factors. The protective portion 13 can be partially or completely arranged around the end edge of the external device where the sub-button 1 or mother buckle 2 is installed, and can also serve to further stabilize the connection between the sub-button 1 or mother buckle 2 and the external device. By providing such a protective portion on the sub-button 1 and the mother buckle 2, not only the overall safety of the connector is enhanced, but also the service life of the external device is extended, and its stability and reliability are improved. This design not only takes into account the functional requirements of the connector itself, but also pays attention to the protection of the external device, thereby providing users with a more comprehensive and reliable solution.

[0054] In a specific embodiment, the dovetail slot 3 is a V-shaped dovetail slot 3 structure, and the dovetail plug 4 is a double-headed V-shaped dovetail plug 4 structure.

[0055] In this embodiment, the double-ended V-shaped dovetail plug 4 is a plug that narrows from a large V-shaped opening toward opposite ends, and does not require a strict V-shape. It only needs to gradually shrink inward along the sliding connection direction to form a wedge shape. Thus, an external device equipped with the double-ended V-shaped dovetail plug 4 can be slidably connected to an external device equipped with a corresponding dovetail slot 3 from the positive direction of the first direction a through the V-shaped dovetail plug 4 at one end, and can also be slidably connected to a matching socket from the reverse direction of the first direction a through the V-shaped dovetail plug 4 at the other end.

[0056] When one end of the double-headed V-shaped dovetail plug 4 on the sub-buckle 1 is used to connect with the dovetail slot 3 of the female buckle 2, and the locking pin 6 provided on the female buckle 2 is locked in cooperation with the locking socket 7 provided on the sub-buckle 1, the other end of the double-headed V-shaped dovetail plug 4 can be used to connect to the V-shaped dovetail socket on other external devices that are compatible with it, and the locking pin 6 provided on the sub-buckle 1 is used to lock in cooperation with the locking socket 7 provided on the dovetail socket.

[0057] Therefore, when the sub-buckle 1 and the mother buckle 2 are set in different external devices, a stable connection between the two devices can be formed. When set on the two ends of the same external device, the external device can be connected to other devices with matching dovetail plugs 4 and dovetail slots 3 on both sides through the dovetail buckles at both ends. The sliding directions are the same and there will be no interference.

[0058] That is, when multiple sub-buckles 1 with dovetail buckles installed at both ends are connected to external devices of the mother buckle 2, the buckling surfaces of the sub-buckles 1 and the mother buckle 2 of different external devices face each other, and the sub-buckle 1 can be smoothly slid into the dovetail slot 3 of the mother buckle 2 through one end of the double-headed V-shaped dovetail plug 4; and the sub-buckle 1 and the mother buckle 2 with their buckling surfaces arranged opposite to each other, because the sliding connection direction of the other end of the double-headed V-shaped dovetail plug 4 of the sub-buckle 1 is the same as the sliding connection direction of the mother buckle 2, they can be synchronously slid into the corresponding dovetail buckles of other devices without interference with the sliding direction, etc.

[0059] Such a design not only increases the connection stability of the dovetail buckle, but also improves its endurance and adaptability. The dovetail slot 3 of the V-shaped structure can better cooperate with the double-headed V-shaped dovetail plug 4 to ensure the firmness and reliability of the connector. This structure not only provides a larger connection area, but also can effectively reduce friction and wear during connection, extending the service life of the fastener. The design of the double-headed V-shaped dovetail plug 4 makes the connection process simpler and faster, and also increases the safety and stability of the connection.

[0060] In a specific embodiment, the first direction a and the second direction b form an angle on the plane where the dovetail slot 3 and the dovetail plug 4 are located, and the angle ranges from 60° to 120°.

[0061] In a specific embodiment, on the plane where the dovetail slot 3 and the dovetail plug 4 are located, the first direction a and the second direction b form an angle, the range of which is limited to between 60° and 120°. Preferably, the angle between the first direction a and the second direction b is 90°. Such a design ensures the correct pairing of the slot and the plug, while also improving the stability and reliability of the connection. The setting of the angle enables the slot and the plug to better cooperate when connected, avoiding incorrect insertion and connection failure. In addition, the range of the angle allows a certain error to a certain extent, making the connection more flexible and easy to operate without affecting the firmness and stability of the connection. This design not only takes into account the functional requirements of the connector, but also takes into account the convenience of use and the practicality of operation, providing users with a more complete connection experience.

[0064] As attached Figure 4As shown, through the dovetail buckle mentioned in Example 1, direct connection between multiple lamps can be achieved. During use, a lamp equipped with a double-headed V-shaped dovetail plug 4 can be slidably connected with a lamp equipped with a corresponding dovetail slot 3 through the V-shaped dovetail plug 4 at one end from the positive direction of the first direction a, and can also be slidably connected with the matching dovetail slot 3 through the V-shaped dovetail plug 4 at the other end from the reverse direction of the first direction a. In this way, the connection of multiple identical lamps can be achieved in turn, which not only achieves a stable connection but also facilitates the disassembly of the lamps, thereby improving convenience and practicality.

[0065] As attached Figure 5 As shown, through the dovetail buckle mentioned in Example 1, the connection between the lamp and other accessories such as lamp stands can be achieved. During use, the lamp equipped with a double-headed V-shaped dovetail plug 4 can be slidably connected with the lamp stand or other accessories equipped with the corresponding dovetail slot 3 through the V-shaped dovetail plug 4 at one end from the positive direction of the first direction a, and can also be slidably connected with the matching dovetail slot 3 through the V-shaped dovetail plug 4 at the other end from the reverse direction of the first direction a. In this way, the connection between multiple lamps and other accessories such as lamp stands can be achieved, which not only achieves a stable connection but also facilitates disassembly, thereby improving convenience and practicality.

[0066] The utility model realizes a snap connection in a first direction by arranging mutually matching dovetail slots and dovetail plugs on the buckle, and realizes a locking connection in a second direction perpendicular to the first direction by arranging mutually matching locking pins and locking holes.
