The mounting assembly 2 includes a support sleeve 25, and the support sleeve 25 is installed at the bottom of the detection seat 1. The mounting assembly 2 also includes a waterproof sleeve 21 and a positioning sleeve 23. The extension end of the cable hose 14 is connected to the waterproof sleeve 21, and the support sleeve 25 is movably matched with the waterproof sleeve 21. An adjusting rod 26 is installed on the support sleeve 25, and the adjusting rod 26 is used to drive the support sleeve 25 to move along the arc-shaped outer wall of the waterproof sleeve 21. The waterproof sleeve 21 is used to wrap around the cable through-hole of the installation tube. When the waterproof sleeve 21 is installed, the cable is inserted into the installation tube from the through-hole of the installation tube to avoid the cable being exposed to the outside and the through-hole of the installation tube being exposed to the outside, thereby protecting the cable and the installation port. The positioning sleeve 23 and the waterproof sleeve 21 are detachable and installed, and a silicone sleeve is arranged between the inner walls of the waterproof sleeve 21 and the positioning sleeve 23 and the outer wall of the installation tube.
