the control rod 7 rotates to drive the rack 27 to rotate, the matched teeth 26 rotate to drive the protective cover 25 to rotate, so that the notch of the protective cover 25 rotates obliquely upwards, at the moment, the surface of the second cylinder 23 leaks out, at the moment, the second electromagnet 24 below the control rod 7 is adsorbed and fixed with the exposed part of the second cylinder 23, the fixation of the control rod 7 is realized, the surface of the second cylinder 23 can be shielded by the protective cover 25, particles generated by explosion are prevented from falling on the contact part of the second cylinder 23 and the second electromagnet 24, the influence of the particles on the adsorption fixation between the second cylinder 23 and the second electromagnet 24 is avoided, when the control rod 7 rotates, the spring 21 is compressed to deform to generate acting force, after the pull rope 11 is loosened, the second electromagnet 24 can be powered off, the spring 21 releases the acting force to drive the control rod 7 to rotate for resetting, otherwise, the resetting of the protective cover 25 can be realized, the notch faces downwards, and the shielding and dust prevention of the protective cover 25 to the second cylinder 23 can be realized.
The above embodiments are only for illustrating the technical solution of the present invention, and are not limiting.
