The sensor holder assembly of claim 3, wherein two of said rocker arms are positioned between two of said pedestals; the base comprises a protection plate arranged on the main support, one side of the second connecting portion faces the rocker arm, the other side of the second connecting portion faces the plate face of the protection plate, and the projection of the protection plate on the second connecting portion covers the plate face.

6. The sensor bracket assembly of any one of claims 1-5, further comprising two securing sleeve units, wherein the two securing sleeve units are correspondingly connected with the two rocker arms one by one, and the two securing sleeve units are used for being correspondingly sleeved and connected with two ends of the sensor one by one;

the fixed sleeve unit is of a round table structure, an inner cavity is formed in the fixed sleeve unit, a port for inserting the sensor into the inner cavity is formed at the end, with the smaller diameter, of the fixed sleeve unit, and the wall, forming the inner cavity, of the fixed sleeve unit is used for being attached to the sensor; and/or, the sensor bracket component also comprises a damping ring, the damping ring is used for being sleeved at the end part of the sensor, and the fixed sleeve unit is sleeved on the damping ring.

7. The sensor carriage assembly of claim 6, wherein the harness unit includes a first engagement plate and a second engagement plate, the first engagement plate including a first semicircular sleeve and the second engagement plate including a second semicircular sleeve, the first semicircular sleeve being removably coupled to the second semicircular sleeve to form the internal cavity between the first semicircular sleeve and the second semicircular sleeve.

8. The sensor-bracket assembly of claim 7, wherein the first plate further comprises a first plate portion attached to an inner side of the first semicircular sleeve, the first plate portion being located at a larger diameter end of the truncated cone shaped structure, the first plate portion being adapted to attach to the rocker arm.

9. The sensor-bracket assembly of claim 8, wherein the second plate further comprises a second plate portion connected to an inner side of the second semicircular sleeve, the second plate portion being in overlapping connection with the first plate portion in an axial direction of the truncated cone-shaped structure.

10. The sensor bracket assembly of claim 9, wherein the second plate portion is located on a side of the first plate portion facing the smaller diameter end of the truncated cone shaped structure, a receiving groove is formed between the second plate portion and the second semicircular sleeve, and the first end of the first plate portion is inserted into the receiving groove to position the first and second engagement plates relative to each other.
