[0053] To facilitate fixing the cable 3, a second extending portion 7 can be disposed on the side surface of the first fixing portion 4, and the extending direction of the second extending portion 7 can be along the length direction of the first fixing portion 4, or along the direction perpendicular to the first fixing portion 4, or other directions that meet the requirements.

[0054] It should be noted that in order to avoid excessive bending of the cable 3 during the fixing process and make the bending angle of the cable 3 within the preset angle range, the distance and angle between the first fixing portion 4 and the second fixing portion 5 can be appropriately adjusted, which is specifically determined according to the actual situation.

[0055] In this specific embodiment, by disposing the second fixing portion 5 on the second extending portion 7, and the second extending portion 7 and the first fixing portion 4 being an integral structure, during actual use, the integral structure of the first fixing portion 4 and the second fixing portion 5 can effectively improve the structural strength. Additionally, by disposing the first fixing portion 4 on the top surface of the cover body 1, it can meet the requirement of installing the sensor 2 on the top surface of the cover body 1.

[0056] Based on the above embodiment, the second extending portion 7 can have a second bend along the axial direction of the cover body 1, and the second fixing portion 5 is disposed at the end of the second bend.

[0057] It should be noted that when there are multiple first fixing portions 4 disposed on the top surface of the same cover body 1, the multiple first fixing portions 4 can be evenly distributed along the circumferential direction of the top surface, and a plurality of second extending portions 7 can be evenly disposed along the axial direction on the outer peripheral edge of the first fixing portion 4. Of course, it can also be other setting methods that meet the requirements, which are specifically determined according to the actual situation and will not be elaborated here.

[0058] In this specific embodiment, by extending the second extending portion 7 along the axial direction of the cover body 1, the distance between the first fixing portion 4 and the second fixing portion 5 can be adjusted. As Figure 3 shown, by disposing the second fixing portion 5 at the end of the second extending portion 7, the height position of the second fixing portion 5 can be higher than the height position of the first fixing portion 4 where the sensor 2 is installed, so as to avoid bending of the cable 3.

[0059] In addition, as Figure 3 shown, by extending the second extending portion 7 along the axial direction of the cover body 1 and away from the cover body 1, it can avoid interference between the cable 3 and the components on the outer periphery of the cover body 1 during installation.

[0060] In a specific embodiment, the first fixing portion 4 can be provided with a first mounting surface 8 for installing the sensor 2, the second fixing portion 5 can be provided with a second mounting surface 9 for fixing the cable 3, and the first mounting surface 8 is parallel to the second mounting surface 9.

[0063] The specific installation method of the lifting and adjusting part on the fixed base mentioned in this specific embodiment can also be other setting forms that meet the requirements, which are specifically determined according to the actual situation and will not be elaborated here.

[0064] It should be noted that during the actual installation of the sensor 2, due to the differences in the model, size, etc. of the sensor 2, the distance between the surface of the sensor 2 in contact with the first mounting surface 8 and the central axis of the cable 3 is different. The central axis of the cable 3 mentioned here refers to the position of the central axis of the end of the cable 3 connected to the sensor 2; when the distance between the surface of the sensor 2 in contact with the first mounting surface 8 and the central axis of the cable 3 changes, the bending angle of the cable 3 will change; in order to adapt to a variety of different sensors 2 and at the same time meet the strict bending angle requirements when the cable 3 is fixed, the relative height of the first mounting surface 8 and the second mounting surface 9 can be set as an adjustable structure. Specifically, the relative height of the first mounting surface 8 and the second mounting surface 9 can be adjusted by adjusting the lifting height of the lifting and adjusting part.

[0065] In this specific embodiment, by setting the lifting and adjusting part with adjustable height, the relative height of the first mounting surface 8 and the second mounting surface 9 can be adjusted, which is beneficial to meeting the strict bending angle requirements when the cable 3 is fixed. At the same time, it can be applied to the installation of a variety of different sensors 2.
