[0023] There are two fixed ear seats 3 and two spiral grooves 2. A threaded groove is provided on the inner side of the spiral groove 2. Bolts are spirally attached to the inner side of the spiral groove 2 and the fixed ear seat 3. A threaded hole is provided on the inner side of the fixed ear seat 3. The inner side of the upper end of the sensor body 1 is attached to the outer side of the electric plug 4 through a sealing ring, which is convenient for fixing the electric plug 4 and the sensor body 1. The limiting rectangular slider 6 is in the shape of a rectangular body, the first rectangular slide groove 7 and the second rectangular limiting groove 9 are in the shape of a rectangular body, and the direction turning groove 8 is in the shape of a cylinder. The first rectangular slide groove 7, the direction turning groove 8, the fixed groove 10 and the second rectangular limiting groove 9 are connected. The second rectangular limiting groove 9 is staggered with the first rectangular slide groove 7, which is convenient for the limiting rectangular slider 6 to slide inside the first rectangular slide groove 7 and the second rectangular limiting groove 9, which has the effect of limiting the electric plug 4. The rectangular body of the fixing groove 10 is opened , the sealing block 12 slides inside the first rectangular slide groove 7 and the fixed groove 10. The number of the first rectangular slide groove 7 and the fixed groove 10 are both two. The outer side of the sealing block 12 fits with the inner side of the upper end of the first rectangular slide groove 7. The number of the spring telescopic rods 11 is two, which plays a role in sealing between the electric plug 4 and the sensor body 1 to prevent impurities from entering the interior of the sensor body 1 and causing damage to the device. The electrical connection groove 20, the triggering electric sheet 15 and the flexible wire 16 are electrically connected. The outer side of the flexible wire 16 slides inside the wire collection column groove 18. The shape of the lower fixed wire column 13 is a hollow cylinder.

[0024] Working process: when the device is in use and needs to be installed, the electric plug 4 fixedly connected to the lower end of the lead body 5 is slid into the sealed installation hole 19 opened on the inner side of the sensor body 1, and at the same time, the limiting rectangular slider 6 fixedly connected to the outer side of the lower end of the electric plug 4 is aligned with the first rectangular slide groove 7 opened on the inner side of the upper end of the sensor body 1, and the electric plug 4 is pressed downward, and the limiting rectangular slider 6 pushes the sealing block 12 to move downward, and the upper end of the spring telescopic rod 11 fixedly connected to the lower end of the sealing block 12 slides inside the lower end of the spring telescopic rod 11. When the electric plug 4 cannot be pressed downward, the limiting rectangular slider 6 is in the direction of rotation opened on the inner side of the sensor body 1. On the inner side of the groove 8, the electric plug-in tube 4 is rotated, and the electric plug-in tube 4 drives the limiting rectangular slider 6 to rotate. When the limiting rectangular slider 6 is away from the sealing block 12, the spring telescopic rod 11 elastically stretches, and the spring telescopic rod 11 pushes the sealing block 12 to move upward. At this time, the outer side of the sealing block 12 is in contact with the inner side of the first rectangular slide groove 7, and at the same time, it is in contact with the outer side of the electric plug-in tube 4. Based on the above principle, the outer side of the electric plug-in tube 4 is in contact with the inner side of the upper end of the sealing mounting hole 19 through the sealing ring, which plays a role in sealing the electric plug-in tube 4 and the sensor body 1, preventing impurities from entering the sensor body 1 and damaging the device. When the limiting rectangular slider 6 rotates to the inner side of the sensor body 1 After the second rectangular limit groove 9 is opened, the outer side of the limit rectangular slider 6 slides inside the second rectangular limit groove 9, and the electric plug 4 continues to be pressed downward. When the electric connection groove 20 opened on the inner side of the lower end of the electric plug 4 slides to the outside of the hollow flashlight 14, the trigger electric sheet 15 fixedly connected to the upper end of the hollow flashlight 14 fits with the upper end of the electric connection groove 20. When the downward pressure is continued, the trigger electric sheet 15 and the hollow flashlight 14 slide on the outside of the lower fixed wire column 13. At the same time, the spring 17 fixedly connected to the inner side of the upper end of the hollow flashlight 14 and the upper end of the lower fixed wire column 13 is squeezed and deformed. Under the elastic thrust of the spring 17, the trigger electric sheet 15 is kept in contact with the electric connection. The effect of the electrical connection of the groove 20 is that even under external impact, the trigger electric sheet 15 can be electrically connected to the lead body 5. When the hollow flashlight 14 moves, the outer side of the lower end of the soft wire 16 fixedly connected to the lower end of the trigger electric sheet 15 slides inside the wire-receiving column groove 18 opened on the inner side of the lower fixed wire column 13. The wire-receiving column groove 18 is connected to the chip, and the wire-receiving column groove 18 belongs to the soft wire. At this time, the chip, the wire-receiving column groove 18, the soft wire 16, the trigger electric sheet 15, the inside of the electric plug-in tube 4 and the electric plug-in tube 4 are electrically connected.
