[0036] In one embodiment, the support mechanism 2 includes two annular brackets 201, a plurality of grooves 202 and a plurality of rollers 203;

[0037] The two annular brackets 201 are symmetrically fixedly connected to the outer side wall of the central sleeve 101, a plurality of grooves 202 are respectively opened on the outer side walls of the two annular brackets 201, and a plurality of rollers 203 are respectively rotatably connected to the inner side walls of the plurality of grooves 202;

[0038] The annular bracket 201 and the roller 203 enable the entire device to slide inside the tube body 54 .

[0039] In one embodiment, the two engaging mechanisms 3 each include a plurality of sector plates 301, an inclined surface portion 302, two elastic rubber rings 303 and a plurality of guide frames 304;

[0040] Among them, a plurality of sector plates 301 are all slidably connected to the inner side wall of the central sleeve 101, the inclined portion 302 is arranged on one side of the sector plate 301, two elastic rubber rings 303 are respectively fixedly connected to the outer side walls of the plurality of sector plates 301, a plurality of guide frames 304 are all fixedly connected to the inner side wall of the central sleeve 101, and the outer side wall of the sector plate 301 is slidably connected to the inner side wall of the guide frame 304;

[0041] The fan-shaped plate 301 slides out of the center sleeve 101 under the action of pressure and drives the elastic rubber ring 303 to move. The guide frame 304 is used to guide the moving fan-shaped plate 301 and increase the contact area between the fan-shaped plate 301 and the center sleeve 101. The elastic rubber ring 303 is used to provide a buffer between the fan-shaped plate 301 and the pipe wall.

[0042] In one embodiment, the two driving mechanisms 4 each include an electric push rod 401, a connecting rod 402 and a tapered slider 403;

[0043] The electric push rod 401 is arranged at the middle of the inner wall of the center sleeve 101, one end of the connecting rod 402 is fixedly connected to the piston rod of the electric push rod 401, and the other end of the connecting rod 402 is fixedly connected to one end of the tapered slider 403.

[0044] The electric push rod 401 is fixed inside the central sleeve 101 through the fixing ear 53, and the conical slider 403 is driven to move by the piston rod of the electric push rod 401 through the connecting rod 402.

[0045] When the utility model is in operation, the conical tube 102 is driven to be inserted into a tube body 54 by moving the central sleeve 101, and the annular bracket 201 and the roller 203 are arranged to enable the entire device to slide in the tube body 54, so as to adjust the position of the device in the pipeline according to actual needs.

[0046] When the position adjustment is completed, the piston rod of an electric push rod 401 drives the conical slider 403 to move through the connecting rod 402, and the moving conical slider 403 squeezes the inclined portion 302, so that the fan plate 301 slides out of the center sleeve 101 under the action of pressure, and drives the elastic rubber ring 303 to move.
