Preferably, the depth of the track groove is greater than the thickness of the sealing ring, the lower part of the track groove is a part of an arc, and the upper part of the track groove is a concave part;

in the technical scheme, the depth of the track groove is greater than the thickness of the sealing ring, so that the sealing ring does not rub against the inner wall of the hydraulic pipe straight pipe in the process that the special tool extends into the hydraulic pipe straight pipe.

Preferably, the lower part of the movable rod is a squeezing part, the squeezing part is matched with the concave part, and the upper part of the movable rod is a part of an arc;

in the technical scheme, the extrusion part interacts with the concave part, so that the sealing ring is extruded, deformed and clamped on the crescent track groove.

Preferably, the track grooves are three in number and correspond to the mounting grooves in the straight pipe of the hydraulic pipe;

in the technical scheme, the number of the positions of the track grooves corresponds to the mounting grooves of the straight pipes of the hydraulic pipes one by one, so that the mounting of a plurality of sealing rings can be realized at one time, and the assembly is efficient.

Preferably, the bottom of the base is also provided with an adjusting bolt, and a locking nut is screwed on the adjusting bolt;

in the technical scheme, the length of the adjusting bolt is used for realizing the positioning effect, namely when the adjusting bolt is abutted against the straight pipe of the hydraulic pipe, the track groove is aligned with the mounting groove, and the locking nut plays a role in locking the adjusting bolt.

Compared with the prior art, the invention has the beneficial effects that: compared with manual installation through calipers, the installation of the invention is efficient and labor-saving, and the installation of a plurality of sealing rings can be realized at one time; compared with the hole sealing ring mounting device, the hole sealing ring mounting device has the advantages that the sealing ring is extruded and deformed, and compared with the stretching deformation, the sealing ring after extrusion deformation can be completely restored to be deformed, the sealing effect is good, and the hole sealing ring mounting device is more convenient and labor-saving when manual mounting is adopted.
