[0042] The working principle of a signal generating device provided by the utility model is as follows:

[0043] When in use, the user first rotates the locking screw 13 to move one end of the locking screw 13 out from the inner side of the positioning hole 32, and then the user rotates the signal generator body 3 to rotate the signal generator body 3 out from the inner side of the shell 1, and the signal generator body 3 and the shell 1 are in a vertical state, and then the user pushes the signal generator body 3 to move the signal generator body 3 toward one end of the control panel 2, and moves the connecting rod 35 to the end of the limiting groove 11 close to the control panel 2, so as to limit the signal generator body 3, and then the user rotates the support plate 34 to rotate the support plate 34 out from the inner side of the rotating groove 33, and the bottom of the support plate 34 is supported on the inner side of the adjusting groove 4.
