The working principle is as follows: when the device is used, the surface of an intelligent instrument is cleaned, the residues of impurities and moisture are reduced, the problem that the instrument is easy to slide and shift in the installation process of the protective shell 1 is solved, after the surface of the instrument is cleaned, the protective shell 1 is arranged at the top of the instrument, then the protective shell 1 is pressed on the instrument from top to bottom, at the moment, the top of the instrument is firstly contacted with the polygonal stabilizing block 25 on the inner side wall of the top of the protective shell 1, then the ejector rod 24 is pushed towards the inside of the arc-shaped piston cavity 22, then the space inside the first arc-shaped flexible pad 23 is compressed, at the moment, the gas inside the first arc-shaped flexible pad 23 is guided into the rodless cavity of the piston cylinder 2 from the first air duct 26, the piston rods 21 on two sides are pushed towards the center, the polygonal stabilizing block 25 on the piston rod 21 is contacted with the instrument, and then the instrument can be positioned in the center inside the protective shell 1, meanwhile, under the combined action of the plurality of polygonal stabilizing blocks 25, the protective shell 1 can be quickly installed on the instrument to protect the instrument, and the problem of damage of external impurities to the instrument is reduced. In the process that polygonal stabilizing block 25 at the top of protective shell 1 contacts with the instrument, when ejector rod 24 pushes first arc flexible pad 23 upwards, it can make arc piston cavity 22 have the inside atmospheric pressure of pole chamber to reduce, and then can make the inside gas of gasbag 28 absorb arc piston cavity 22 by polygonal stabilizing block 25 have the pole intracavity, a plurality of polygonal stabilizing blocks 25 will be pulled into the downwarping state by gasbag 28 this moment, this setting can make when polygonal stabilizing block 25 and instrument contact, increase the area of contact of polygonal stabilizing block 25 and instrument, and then the problem of rocking appears between reducible instrument and protective shell 1, polygonal stabilizing block 25 that can independently move simultaneously can carry out the adaptive cover of snatching to the instrument, and then can make the more stable of protective shell 1 installation on the instrument. By adding the second flexible magnet 31 at the position where each arc-shaped piston cavity 22 is contacted with the second conduit 29, the mandril 24 can deflate the second conduits 29 at the bottom of the first arc-shaped flexible pad 23 one by one in the process of upwards positioning the first arc-shaped flexible pad 23 by the mandril 24, firstly the second conduit 29 close to the mandril 24 is pulled, at the moment, the polygonal stabilizing block 25 close to the center can be rolled up to grab the instrument, the arrangement can avoid the problem that the polygonal stabilizing blocks 25 are not pressed tightly due to the fact that a plurality of polygonal stabilizing blocks 25 are curled simultaneously and stress surfaces of the polygonal stabilizing blocks 25 and the instrument are dispersed, and in the process of continuously upwards moving the mandril 24, more second conduits 29 can deflate, the polygonal stabilizing blocks 25 far from the center can be curled, so that the polygonal stabilizing blocks 25 are contacted with the instrument one by one, each polygonal stabilizing block 25 can be pressed with the instrument independently, the problem of too large stress dispersion caused by the fact that the plurality of polygonal stabilizing blocks 25 are in contact with the instrument at the same time is solved, and meanwhile, the polygonal stabilizing blocks 25 are curled one by one, so that the polygonal stabilizing blocks 25 can independently carry out adaptive grabbing on the external shapes when facing the instruments with different shapes. By arranging the soft chock 4 and the flexible washer 41 on the first arc-shaped flexible pad 23; when the first arc-shaped flexible pad 23 is in contact with the inner side wall of the arc-shaped piston cavity 22, the tightness of the second guide pipe 29 is improved, so that the strength of the single polygonal stabilizing block 25 is higher when the polygonal stabilizing blocks 25 are used for adaptive grabbing of the instrument one by one, and the condition that the polygonal stabilizing block 25 is bent in advance due to gas leakage into the second guide pipe 29 which is not opened is avoided; when the individual polygonal stabilizing blocks 25 are bent in advance, the air pressure inside the second guide tube 29 for controlling the pressing of the polygonal stabilizing blocks 25 is lowered, so that the degree of pressing force of the polygonal stabilizing blocks 25 is reduced. Through being equipped with sawtooth rubber block 5 and sponge piece 51 in the bottom of polygon stabilizing block 25, can be in deformation when polygon stabilizing block 25 and instrument contact, and then increase the frictional force of instrument and polygon stabilizing block 25, simultaneously because of being equipped with sponge piece 51 in the bottom of polygon stabilizing block 25, can absorb remaining moisture on the instrument, when reducing moisture and corroding the instrument, the stability of multiplicable protecting crust 1 when the instrument top. In the process of contacting the polygonal stabilizing block 25 with the instrument, the suction cup 63 can contact with the surface of the instrument, then the sliding rod 62 can slide in the polygonal stabilizing block 25, and meanwhile, the second arc-shaped flexible pad 61 is pushed upwards in the cavity 6, at the moment, the gas in the suction cup 63 is extracted into the rod cavity of the cavity 6 through the air duct 64, the grabbing strength of the polygonal stabilizing block 25 to the instrument can be improved by reducing the air pressure between the suction cup 63 and the surface of the instrument, and when the polygonal stabilizing block 25 can carry out self-adaptive grabbing to the instrument, the phenomenon that the polygonal stabilizing block 25 can shift on the instrument is reduced. In the process that the suction disc 63 adsorbs the instrument, the sponge block 51 can also deform, at the moment, the water bag 7 in the sponge block 51 can contact the water bag 7, then the water in the water bag 7 can flow into the sponge block 51 and the side wall of the suction disc 63, the sealing performance of the suction disc 63 is improved, the amount of external gas which can enter the suction disc 63 can be reduced, the grabbing force of the suction disc 63 on the instrument is further improved, and the stability of the protective shell 1 on the top of the instrument is improved; moreover, the bent blade 72 is provided so that when the water bladder 7 is punctured, water will flow first in a direction approaching the suction cup 63. When instrument top was installed to protecting crust 1, the border of protecting crust 1 bottom will contact with the pipeline, and slider 81 will remove the inside of bearing spout 8 under the support of sealing rubber area 82 this moment, and sealing rubber area 82 will completely cut off the inside and the outside air of protecting crust 1 this moment and come, and then can make protecting crust 1 further improve the protectiveness of instrument. A plurality of groups of sealing flexible teeth 91 are arranged at the bottom of the sealing rubber belt 82; can be when sealing rubber belt 82 and pipeline contact, sealed flexible tooth 91 can open the impurity on the pipeline, reduces the residual volume of impurity at sealing rubber belt 82 bottom, and then the laminating degree of multiplicable sealing rubber belt 82 and pipeline contact.
