[0027] Furthermore, the connecting bracket 7 includes a second U-shaped plate 71, and the front and rear sides of the second U-shaped plate 71 are fixedly connected to the second cylinder 72, the inner wall of the first strip hole 6 and the inner wall of the fixed bracket 9 are in contact with the surface of the second cylinder 72, the second cylinder 72 can rotate or slide in the first strip hole 6, and the inner wall of the second U-shaped plate 71 is fixedly connected to the surface of the sensor body 8.
[0028] Furthermore, the fixing bracket 9 includes a bolt 91, the left side of the bolt 91 contacts the right side of the strip plate 5, the surface of the bolt 91 is threadedly connected with a threaded barrel 92, the surface of the threaded barrel 92 is fixedly connected with a connecting plate 93, the left side of the connecting plate 93 is fixedly connected with a third U-shaped plate 94, the inner wall of the third U-shaped plate 94 contacts the surface of the strip plate 5, the front and rear sides of the third U-shaped plate 94 are provided with second strip holes 95, the left side of the inner wall of the second strip hole 95 is bonded with an arc-shaped rubber strip 96, the surface of the first cylinder 3 and the surface of the second cylinder 72 are both in contact with the inner wall of the arc-shaped rubber strip 96, when the bolt 91 rotates, through the cooperation of the bolt 91 and the threaded barrel 92, the arc-shaped rubber strip 96 is pressed against the first cylinder 3 The pressure of the column 3 or the second cylinder 72 changes. When the arc rubber strip 96 is in close contact with the first cylinder 3, the strip plate 5 cannot rotate due to the cooperation of the arc rubber strip 96 and the first cylinder 3. When the arc rubber strip 96 is separated from the first cylinder 3, the strip plate 5 can rotate on the first cylinder 3. When the arc rubber strip 96 is in contact with the second cylinder 72, the friction between the arc rubber strip 96 and the second cylinder 72 prevents the second cylinder 72 from rotating, and the friction between the bolt 91 and the strip plate 5 prevents the second cylinder 72 from sliding in the first strip hole 6. When the arc rubber strip 96 is separated from the second cylinder 72, the second cylinder 72 can slide or rotate in the first strip hole 6.
[0029] Furthermore, a limiting ring 10 is fixedly connected to the surface of the bolt 91 , and the limiting ring 10 prevents the bolt 91 and the threaded tube 92 from being separated.

A magnetic block 13 is fixedly connected to the right side of the limiting block 11. The bottom of the magnetic block 13 contacts the upper surface of the connecting plate 93. When the limiting block 11 is inserted into the third U-shaped plate 94, the magnetic block 13 attracts the third U-shaped plate 94. The limit block 11 can be fixed in the third U-shaped plate 94 by the force, and the bolt 91 on the fixed bracket 9 can be locked by the cooperation of the limit ring 10, the limit block 11, the groove 12 and the magnetic block 13, so that the bolt 91 is not easy to rotate after the laser ranging sensor is vibrated, and the fixed bracket 9 and the first cylinder 3 or the second cylinder 72 are not easy to loosen, so that the stability of the sensor body 8 is improved. At the same time, the limit block 11 can be directly pulled out from the third U-shaped plate 94.
[0031] Furthermore, the suction force of the magnetic block 13 on the connecting plate 93 is greater than the sum of the gravity of the limiting block 11 and the magnetic block 13 .
[0032] The utility model is a laser distance measuring sensor based on RS485. The use principle is as follows: firstly, the mounting plate 1 is mounted on the mounting frame, then, by rotating the bolt 91 at the first cylinder 3, the pressure of the arc-shaped rubber strip 96 at the first cylinder 3 on the first cylinder 3 is reduced, and the strip plate 5 can rotate around the first cylinder 3, then, by rotating the bolt 91 at the second cylinder 72, the pressure of the arc-shaped rubber strip 96 at the second cylinder 72 on the first cylinder 3 is reduced, and the second cylinder 72 can rotate or slide in the first strip hole 6, then, by moving or rotating the sensor body 8 and the strip plate 5, the sensor body 8 and the mounting plate 1 are connected. The angle or distance between the two cylinders changes. When the sensor body 8 is adjusted to a suitable position, the pressure of the arc-shaped rubber strip 96 on the first cylinder 3 is increased by rotating the bolt 91 at the first cylinder 3, and the strip plate 5 cannot rotate due to the friction between the arc-shaped rubber strip 96 and the first cylinder 3. Then, the pressure of the arc-shaped rubber strip 96 on the second cylinder 72 is increased by rotating the bolt 91 at the second cylinder 72, and the friction between the arc-shaped rubber strip 96 and the second cylinder 72 prevents the second cylinder 72 from rotating. At the same time, the friction between the bolt 91 and the strip plate 5 prevents the second cylinder 72 from sliding in the first strip hole 6.
[0033] In addition: It should be noted that the above specific implementation is only an optimization scheme of this patent. Any changes or improvements made by technicians in this field based on the above concept are within the scope of protection of this patent.
