[0054] In use, the installation cylinder 61 is arranged on the shell of the underwater robot, and then the nut 62 is threadedly connected on the installation cylinder 61 inside the shell of the underwater robot. The shell of the underwater robot is clamped by the nut 62 and the shell 1, so as to fix and install the shell 1 on the underwater robot. The line of the line board and the wave band switch 2 passes through the threading hole 12 and the installation cylinder 61 and is arranged inside the shell of the underwater robot. The notch groove 621 is arranged on the nut 62, so that the nut 62 can be directly sleeved on the line, without the need of sleeving the nut 62 at the end of the line, thereby facilitating the threadedly connecting of the nut 62 on the installation cylinder 61.

[0059] Under the action of the limiting block 21 and the limiting groove 14, the wave band switch 2 can only slide along the length direction of the limiting groove 14 in the placing groove 11, and cannot rotate. When the operator rotates the amplification knob 3, the knob on the wave band switch 2 is driven to rotate, so that the amplification knob 3 can control the working state of the wave band switch 2. At the same time, the amplification knob 3 drives the spring ball head plunger 4 to rotate, so that the ball head end of the spring ball head plunger 4 slides into or out of the clamping groove 13, thereby producing a jerk feeling. On the one hand, the large amplification knob 3 is used to replace the knob on the wave band switch 2, so that the operator can more accurately control the underwater robot to work. On the other hand, the spring ball head plunger 4 and the clamping groove 13 produce a jerk feeling, which prompts the operator, so that the operator can perceive the rotation state of the amplification knob 3, thereby enabling the operator to more accurately control the underwater robot.

[0060] The above are the preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
