In order to facilitate the turning of the knob blocking piece 5 to be clamped on the knob, a limiting groove 211 is formed in the outer wall of the knob 2, the knob blocking piece 5 is turned and made to overcome the elastic movement of the torsion spring 6, and one end of the knob blocking piece 5 is clamped in the limiting groove 211 and limits the movement of the knob 2.
The knob 2 has three symmetrical triangular limiting grooves 211 for locking any one of the positions of Remote (REM), STOP and Local (LOC).
The knob blocking piece 5 is provided with a clamping edge 51, a limiting edge 52 and a lock hole 53, the limiting edge 52 in the knob blocking piece 5 is abutted against the outer wall of the electric cover 1 under the elastic action of the torsion spring 6, the knob blocking piece 5 is pulled to enable the clamping edge 51 of the knob blocking piece 5 to be clamped in the limiting groove 211, the lock hole 53 is exposed out of the outer wall of the electric cover 1, and the padlock 7 is locked in the lock hole 53.
The knob separation blade 5 is a special-shaped piece, a bending piece (namely a limit edge 52) exposed outside the electric cover 1 is convenient to pull out by a starter, a small hole is arranged at one end of the knob separation blade and connected with the torsion spring 6, and when the padlock 7 is not used, the knob separation blade 5 is rebounded and hidden under the panel 3. The other end is designed with a large hole of the padlock 7 (i.e. the keyhole 53).
In order to install the knob 2 conveniently, a knob hole 111 is formed in the electric cover 1, the knob 2 is rotatably connected into the knob hole 111 through a bearing, three limiting holes 112 are formed in the bottom surface of the knob hole 111, and the three limiting holes 112 are conveniently and correspondingly arranged on the STOP gear, the REM gear and the LOC gear.
