[0024] like Figure 1 and Figure 2As shown, the adjustment assembly includes two card seats 13, two card seats 2 14, a connecting rod 15, a limit block 16 and a card block 17. The adjacent ends of the two card seats 13 are fixedly connected to the left and right ends of the sensor head 2 respectively. The card seat 13 is designed to cooperate with the card seat 2 14 to adjust the angle of the sensor head 2. The distant ends of the two card seats 2 14 are fixedly connected to the left and right ends of the inside of the clamp 1 respectively. The outer side of the connecting rod 15 is slidably connected to the inside of the sensor head 2. The connecting rod 15 is designed to cooperate with the limit block 16 and the card block 17 to apply pressure to the left and right ends of the clamp 1.

The limit block 16 is designed to limit the connecting rod 15.

[0025] like Figure 1-3 As shown, the reset assembly includes a reset spring 9, which is sleeved on the outer side of the card column 7. The reset spring 9 is designed to push the reset ring 8, and the card column 7 is reset by the reset ring 8. The reset spring 9 is arranged inside the sliding groove 6, and the top of the reset spring 9 contacts the bottom end of the reset ring 8.

The reset ring 8 is designed to facilitate the reset spring 9 to reset the card column 7 through it, and the fixed sleeve 5 is designed to cooperate with the fixing groove 12 through the card ball 11, so as to facilitate the fixing of the fixing plate 4 and the bottom plate 3 together. The far ends of the two card balls 11 are respectively in contact with the left and right ends of the inside of the fixing groove 12, and the close ends of the two card balls 11 are in contact with the left and right ends of the card column 7. The card ball 11 is designed to be tightly engaged in the inside of the fixing groove 12 under the push of the card column 7, so as to tightly fix the bottom plate 3 and the fixing plate 4 together.

[0026] Working principle: the photoelectric sensor is installed at the required place through the fixing plate 4. When the photoelectric sensor needs to be disassembled quickly, by pressing the card column 7, the card column 7 is squeezed through the reset ring 8 to squeeze the reset spring 9, and the groove set in the card column 7 is parallel to the card ball 11, so that the card ball 11 is no longer tightly engaged in the inside of the card ball 11. At this time, the fixing sleeve 5 can be taken out from the inside of the bottom plate 3 and the fixing plate 4. At this time, the photoelectric sensor can be maintained and replaced. After maintenance and replacement, by pressing the card column 7, the groove of the card column 7 is parallel to the card ball 11, so that the fixing sleeve 5 can be reinserted into the inside of the bottom plate 3 and the fixing plate 4. After releasing your hand, the reset ring 8 will reset the card column 7 under the push of the reset spring 9, and the card column 7 will also push the card ball 11, so that the card ball 11 is tightly engaged in the inside of the fixing groove 12. The photoelectric sensor can be disassembled quickly and easily, making maintenance work easier, reducing the complexity of maintenance and improving the efficiency of maintenance work. When the lifting angle of the clamp seat 1 needs to be adjusted, the block 17 is broken up by hand so that the block 17 no longer squeezes the clamp seat 1 through the connecting rod 15 and the limit block 16, and the engagement of the clamp seat 2 14 and the clamp seat 1 13 is also loosened at this time. At this time, the lifting angle of the clamp seat 1 can be adjusted. After the angle is adjusted, align the clamp seat 2 14 with the clamp seat 1 13, and break the block 17 down again by hand. The block 17 will cooperate with the connecting rod 15 and the limit block 16 to squeeze the clamp seat 1, so that the clamp seat 2 14 is tightly engaged with the clamp seat 1 13, thereby fixing the lifting angle of the clamp seat 1, and by adjusting the lifting angle of the clamp seat 1, it is more suitable for the use scenario, thereby improving the flexibility and applicability of use.
