[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] Please see Figure 1-4 As shown, this embodiment is a micro switch, including:

[0032] The protective component includes a main shell 1 and a secondary shell 11, with the secondary shell 11 overlapping the right side of the main shell 1.

[0033] The mounting components include a first groove 9, a slider 6, a slide bar 7, a moving block 5, an insert rod 4, a mounting block 2, a mounting slot, a drive plate 3, an elastic sheet 8, a limiting slot 10, and a third groove 19.

[0034] The upper end face of the main shell 1 is fixedly provided with a first groove 9, a slider 6 is slidably sleeved in the first groove 9, and slider rods 7 are fixedly connected to both the front and rear sides of the slider 6. A moving block 5 is fixedly connected to the lower end face of the slider 6, and an insert rod 4 is fixedly connected to the right side face of the moving block 5. An installation block 2 is sleeved on the surface of the insert rod 4. An installation groove is provided in the installation block 2. A drive plate 3 is fixedly installed on the upper end face of the installation block 2. An elastic sheet 8 is sleeved in the first groove 9.

[0035] The first groove 9 allows the slider 6 to slide within the limited space of the main shell 1, and together with it, drives the insertion rod 4 to move, so that the insertion rod 4 can smoothly enter into the moving block 5 and disengage from the moving block 5, thus completing the installation and disassembly of the drive plate 3.

[0036] One side of the elastic sheet 8 is fixedly connected to the main shell 1, and the side of the elastic sheet 8 facing away from the main shell 1 is fixedly connected to the surface of the slider 6.

[0037] The elastic sheet 8 can compress the slider 6 when it moves to the left, and when the elastic sheet 8 is not under force, the elastic sheet 8 can control the slider 6 to return to its original position.

[0038] A limiting groove 10 is provided on the upper end face of the main shell 1, and the surface of the slide rod 7 is slidably sleeved in the limiting groove 10;

[0039] By using the limiting groove 10, when the slide rod 7 slides along the inner wall of the limiting groove 10, the movement of the slider 6 is ensured to be stable and smooth.

[0040] The main shell 1 has a third groove 19 inside, the surface of the movable block 5 is fitted into the third groove 19, the first groove 9 and the third groove 19 are connected, and the first groove 9 is connected to the limiting groove 10.

[0041] Working principle: When the drive board 3 needs to be installed, the mounting block 2 is pushed downward between the main shell 1 and the sub-shell 11. The pushing force can push the insertion rod 4 to the left and drive the moving block 5. When the mounting groove in the mounting block 2 is in a relative position with the insertion rod 4, the elastic plate 8 uses its own elasticity to control the sliding rod 7 and the sliding plate to slide to the right. The moving block 5 drives the insertion rod 4 to push into the mounting block 2, completing the installation of the drive board 3. This process only requires pushing the mounting block 2 downward between the main shell 1 and the sub-shell 11. When the drive board 3 needs to be disassembled or replaced, push the slider 6 to move towards the elastic plate 8 and squeeze it to make the insertion rod 4 separate from the mounting block 2. The operation process is convenient and smooth. The position restriction allows the mounting block 2 to quickly find the position with high accuracy.

[0042] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment 1, and the mounting components also include a fixing frame 14, a partition 15, a spring 16, a limiting block 17, a limiting frame 12, a through hole 13, and a push plate 18;

[0043] A fixed frame 14 is fixedly connected inside the main shell 1. A partition 15 is fixedly connected inside the fixed frame 14. Springs 16 are fixedly installed on both the upper and lower sides of the partition 15. Limiting blocks 17 are fixedly connected to one end of each of the two springs 16 facing away from each other. The surface of the limiting block 17 is slidably fitted with the limiting frame 12.

[0044] The partition 15 enables the installation of two springs 16, which in turn drive the movement of the limiting block 17, allowing the limiting block 17 to smoothly enter the limiting frame 12.

[0045] A through hole 13 is provided inside the limiting frame 12, and one side of the limiting frame 12 slides into the main shell 1;

[0046] By setting through hole 13, the limiting block 17 can smoothly enter the limiting frame 12 through through hole 13;

[0047] Push plates 18 are fixedly installed on the front of the two limiting blocks 17, and the surface of the push plates 18 is slidably sleeved in the fixed frame 14.

[0048] Working principle: When the main shell 1 and the secondary shell 11 need to be installed, the operator moves the secondary shell 11 through the direction of the main shell 1, so that the limiting frame 12 moves to the left along the inclined surface of the limiting block 17. During this process, the limiting block 17 is subjected to force and moves towards the center of the fixed frame 14, compressing the spring 16. When the through hole 13 and the limiting block 17 are in relative positions, the spring 16 begins to use its own elasticity to control the two limiting frames 12 to move outward at the same time until they are inserted into the limiting frame 12, completing the connection between the main shell 1 and the secondary shell 11. The process is simple, convenient and quick.

[0049] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
