The design of the placement sleeve 4 is to facilitate the placement of other structures inside it.

[0034] As Figure 1 and Figure 3 shown, the positioning component includes a rotating column 11 and an extrusion block 13. The design of the rotating column 11 is to drive the extrusion block 13 when rotating. The outer side of the rotating column 11 is rotatably connected inside the sliding groove 10. The outer side of the extrusion block 13 is slidably connected inside the sliding groove 10. The design of the extrusion block 13 is to extrude the mounting plate 2 under the drive of the rotating column 11 to complete positioning. The rear end of the rotating column 11 is fixedly connected with a rotating piece 12. The design of the rotating piece 12 is to facilitate the connection between the rotating column 11 and the extrusion block 13.

The design of the rotating knob 15 is to rotate it, thereby rotating the rotating column 11.

[0036] Working principle: When the opener 1 needs to be installed on the mounting plate 2, first place the opener 1 on the mounting plate 2. When placing the mounting plate 2, first rotate the rear plate 16 so that the rear plate 16 will not be blocked by the mounting plate 2, and let the placement sleeve 4 face the opening at one end of the through slot 3. The through slot 3 is an internally provided slot in the opener 1 to facilitate the sliding of the placement sleeve 4. When the placement sleeve 4 needs to pass through the mounting plate 2, press the pressing column 5 by hand so that the clamping ball 9 can be aligned with the groove on the pressing column 5. Thus, when the placement sleeve 4 passes through the through slot 3, the clamping ball 9 can be pressed into the interior of the placement sleeve 4. When the opener 1 is tightly fitted with the mounting plate 2, release the hand pressing the pressing column 5, and the pushing spring 7 will push the pushing piece 6, thereby driving the pressing column 5 to squeeze the two clamping balls 9 apart, making the clamping balls 9 protrude from the placement sleeve 4 again to fix the opener 1 and the mounting plate 2. At this time, rotate the rear plate 16 again to make the rear plate 16 return to its original shape and fit against the rear of the mounting plate 2. By squeezing the clamping balls 9 apart with the pressing column 5 to make a part of the clamping balls 9 protrude from the placement sleeve 4, the opener 1 and the mounting plate 2 are fixed, which can avoid using tools to install the distribution switch, making the installation process simple, shortening the time of the installation process, and improving the installation efficiency. When the position of the opener 1 on the mounting plate 2 needs to be adjusted, rotate the rotating knob 15 by hand, thereby rotating the rotating column 11. The rotating column 11 will drive the extrusion block 13 to move inside the sliding slot 10 and move away from the mounting plate 2. At this time, the position of the mounting plate 2 can be moved. After determining the position of the opener 1, rotate the rotating knob 15 by hand again, thereby rotating the rotating column 11, so that when the rotating column 11 rotates, it drives the extrusion block 13 to squeeze the mounting plate 2, thereby fixing the position of the opener 1. By driving the rotating column 11 to drive the extrusion block 13 to squeeze and separate from the mounting plate 2, the position of the opener 1 can be moved, enabling the opener 1 to be adjusted according to requirements in the position on the mounting plate 2, improving the flexibility and applicability of use.
