During the use, the outer wall of launching tube 31 and the inner wall contact of guide cylinder 1, the piston of piston spring 32 and the cavity cooperation of launching tube 31, launching tube reset spring 33's one end and piston connection, the other end and the inner wall connection of guide cylinder 1, aerify the back in the guide cylinder 1, atmospheric pressure promotes the piston and compresses piston spring 32, and meanwhile, launching tube 31 slides along guide cylinder 1 and finally is blockked by slider 14, and launching tube 31 forms potential energy, and launching tube reset spring 33 extends.
When the device is used, the launching button 34 is pressed to pull the traction wire 35 to roll along the pulley 36 to lift the slider 14, the structure is compact, and the response is quick.
When the device is used, pressure applied to the pressing column compresses the pressing spring, the pressing column pulls the traction wire 35 to lift the sliding block 14, the sliding block 14 slides into the sliding groove 13, and after the pressing is cancelled, the pressing spring pushes the pressing column to reset, so that the device is flexible and reliable.
Before the use, adopt the magnetizer to magnetize magnetism nail 4, prolong magnetism nail 4 magnetism, after magnetism nail 4 jets into the crack periphery, adsorb the magnetic mortar after the injection crack, discharge water and the air in the crack.
The above-described embodiments are merely preferred embodiments of the present invention, and should not be construed as limiting the present invention, and features in the embodiments and examples in the present application may be arbitrarily combined with each other without conflict. The protection scope of the present invention is defined by the claims, and includes equivalents of technical features of the claims. I.e., equivalent alterations and modifications within the scope hereof, are also intended to be within the scope of this invention.
