Multiple locking components are provided and symmetrically distributed on the same side of the base plate. A driving component is installed between the symmetrically disposed locking components. The middle part of the driving component is fixedly connected to the lever and rotates under the drive of the lever. The two ends of the driving component abut against the symmetrically disposed locking components. The two ends of the spring are respectively connected to the symmetrically disposed locking components. Under the drive of the spring and the driving component, the symmetrically disposed locking components reciprocate.

[0009] Preferably, the lever includes a recessed portion and a contact portion.

[0028] To more clearly illustrate this application, the following description, in conjunction with the accompanying drawings, is provided. Of course, the scope of protection of this application is not limited to this description. Simple substitutions that can be made by a person skilled in the art without creative effort are all within the scope of protection of this application.

[0029] Please refer to Figures 1 to 9; this application provides a quick-assembly and disassembly structure, including a mounting plate 7, a connector 8, and a snap-fit ​​unit. The mounting plate 7 has a threaded hole 71 in the center, and snap-fit ​​interfaces 72 on both sides of the threaded hole for the locking member 4 inside the snap-fit ​​unit to extend out. The connector 8 is located at the lower part of the mounting plate 7, and has a mounting hole in the center that matches the snap-fit ​​unit. The mounting plate 7 has protruding limiting blocks 74, symmetrically arranged on both sides of the mounting plate 7. The connector 8 has grooves 84 that match the limiting blocks 74. The quick assembly and disassembly of the device are achieved through the cooperation of the snap-fit ​​unit, the limiting blocks 74, and the grooves 84. In this embodiment, the device is effectively snapped in place by the locking member of the snap-fit ​​unit, and quick installation and disassembly are achieved through the cooperation of the limiting blocks and the grooves, meeting usage requirements.

[0030] The mounting plate 7 has a snap-fit ​​area adapted to the device on the side away from the snap-fit ​​unit. Multiple snap-fit ​​pieces 73 are provided along the edge of the snap-fit ​​area, and multiple reinforcing ribs are provided within the snap-fit ​​area. In this embodiment, the mounting plate is first fixed to the device. The snap-fit ​​pieces ensure effective contact with the device, while the reinforcing ribs effectively increase the strength of the mounting plate, preventing damage during use.

[0031] The connector includes a horizontally positioned connecting ring 81 and load-bearing plates at both ends of the connecting ring. Each load-bearing plate has a load block 82, and the center of each load block 82 has a groove 83 that matches a limiting block. The edge of the groove 83 has a bevel. In this embodiment, the connecting ring ensures a stable connection between the connector and the lever-type quick-release structure. The groove on the load block enables "quick installation," meaning that when the mounting plate moves along the extension angle of the load block, the limiting block quickly and stably engages in the groove, achieving a limiting effect. Combined with the lever-type quick-release structure, this allows for rapid installation of the equipment.

[0032] The locking unit includes a lever 1, a base plate 2, a spring 3, and a locking element 4. The lever 1 and the locking element 4 are respectively located on both sides of the base plate 2. There are multiple locking elements 4, symmetrically distributed on the same side of the base plate 2. A driving element 5 is installed between the symmetrically arranged locking elements 4. The middle part of the driving element 5 is fixedly connected to the lever 1 and rotates under the drive of the lever 1. The two ends of the driving element 5 abut against the symmetrically arranged locking elements 4 respectively. The two ends of the spring 3 are respectively connected to the symmetrically arranged locking elements 4. Under the drive of the spring 4 and the driving element 5, the symmetrically arranged locking elements 4 reciprocate. In this embodiment, the rotation of the lever drives the drive component to rotate. When the drive component rotates, it causes the two symmetrically arranged locking components to move away from each other. When the device to be clamped is placed, the two symmetrically arranged locking components move closer to each other under the action of the spring, thereby locking and fixing the device. In actual application, a fixing plate adapted to the locking component is provided. The fixing plate and the base plate cooperate with each other to form a cavity for installing the locking component and the spring, thereby ensuring that the locking component can only move in the horizontal direction. In order to ensure that the locking component will not shift during the movement, a movement groove adapted to the locking component can be provided on the side of the base plate facing the locking component, making the movement of the locking component smoother.

[0033] To achieve the above solution, the lever 1 includes a recessed portion 12 and a contact portion 11. The contact portion 11 is located on both sides of the recessed portion 12 and is fixedly connected to the recessed portion 12 as an integral structure. The recessed portion 12 has a "U"-shaped structure, which is adapted to the base plate 2. The middle part of the recessed portion 12 is fixedly connected to the driving component 5 by screws. In this embodiment, the lever adopts a special structural design to ensure that the overall structure is more compact; and the base plate is provided inside the recessed portion, thereby protecting the base plate.

[0034] The locking component 4 includes a fixed base and a latch. The latch is located at the upper end of the fixed base and is fixedly connected to the fixed base as an integral structure. The lower part of the fixed base has a drive groove 41 adapted to the drive component. The drive groove 41 has an arc-shaped structure, and the upper end of the drive groove 41 has a fixing pin adapted to the spring. The actuating component 5 has an elliptical structure, and the long half-axis region of the actuating component 5 extends into the drive groove 41 of the locking component 4. In this embodiment, an arc-shaped drive groove is provided at the lower end of the locking member, and the actuating member has an elliptical structure. When in the clamping state, the edge of the actuating member fits against the drive groove, which further reduces the distance between the symmetrically arranged locking members. When it is necessary to release the clamping state, the actuating member rotates along the drive groove. When the long half-axis region of the actuating member is perpendicular to the locking member, the clamping distance between the locking members is at its maximum. When the external force disappears, the actuating member rotates in the opposite direction under the action of the spring, so that the locking member clamps the device. In actual use, a limiting member can be provided inside the drive groove to adjust the opening distance.

[0035] In actual use, a protective housing 6 is also provided. The protective housing 6 is located on one side of the lever 1 and is fixedly connected to the base plate 2. A through hole 62 is provided on the side for the lever 1 to extend out. A limiting baffle 61 flush with the through hole is provided inside the protective housing 6. In this embodiment, a protective housing is provided to protect the entire structure, and the presence of the limiting baffle can effectively prevent the lever from moving too erratically.
