As can be seen from the above description, the sealing screw 2 generally comprises a plurality of rod segments with different diameters, and the rubber sealing sleeve 4 is sleeved at the position where the diameter of the sealing screw 2 is the smallest;
the thicker sealing element 41 is arranged, so that the contact surface between the sealing element 41 and the outer cladding 11 is larger, and the sealing performance of the sealing screw rod 2 and the threaded hole is improved; but this makes it difficult for the seal 41 to expand its inner diameter to slide over the sealing screw 2 or the sealing nut 3 or the turnnut 5.
The rubber sealing sleeve 4 is divided into a sealing element 41 and a conical sleeve; the cylindrical gland nut 3 is provided, so that the sealing element 41 can be more tightly attached to the circumferential surface of the gland nut 3. The tapered sleeve is made of thin and soft rubber, so that the inner diameter of the tapered sleeve can be conveniently expanded and then can slide on the screwing nut 5 and the sealing screw rod 2.
Further, the fourth step is followed by adhering the rubber sealing boot 4 and the sealing screw 2 by using adhesive.

The method for conveniently sealing the bolt-ball joint according to claim 1, wherein the step in the second step comprises the following steps: before the rubber material is subjected to compression molding by a hot vulcanization process, wrapping the bolt ball and the screw cap obtained in the step one with the rubber material, putting the wrapped bolt ball and the screw cap into a spherical mold subjected to compression molding by the hot vulcanization process, preheating the spherical mold until the rubber material is in a non-Newtonian fluid state, opening the mold, and supplementing the rubber material until the rubber material is filled in the mold.
6. The method for conveniently sealing the bolt-ball joint according to claim 1, wherein the step four is specifically:
a screwing nut is sleeved on the sealing screw rod and is in a pyramid shape matched with a spanner;
a sealing nut is in a cylindrical shape, and the diameter of the sealing nut is equal to that of the taking-out hole;
wrapping the sealing screw rod, the sealing nut and the screwing nut by using a rubber sealing sleeve;
screwing the sealing screw rod into the threaded hole of the bolt ball obtained in the third step;
sliding the rubber sealing sleeves on the sealing screw rod, the sealing nut and the screwing nut to expose the outer surface of the screwing nut, rotating the knob nut by using a wrench, further driving the sealing nut to rotate to enable the sealing nut to abut against the bolt ball, enabling the sealing nut to abut against the bolt ball, and then sliding the rubber sealing sleeves to reset;
the rubber gland and outer wrap are bonded using adhesive.
7. The convenient method for realizing the bolt-ball joint seal according to claim 6, wherein the rubber sealing sleeve comprises a sealing element and a conical sleeve, the end parts of the sealing element are mutually abutted, the sealing element is attached to the whole circumferential surface of the sealing nut, and the conical sleeve is sleeved on the screwing nut and the sealing screw rod;
the "sliding of the rubber sealing sleeves over the sealing screw, the sealing nut and the screwing nut" is in particular a sliding of the tapered sleeves over the sealing screw, the sealing nut and the screwing nut.
8. The method of facilitating a bolted spherical joint seal according to claim 7, characterized in that the average thickness of the seal is greater than that of the tapered sleeve.
9. The method for facilitating the sealing of a bolted spherical joint according to claim 7, further comprising, after step four, adhering the end of the seal and the end of the tapered sleeve using an adhesive glue.
10. The method for conveniently sealing the bolt-ball joint according to claim 1, wherein the fourth step is followed by adhering a rubber sealing boot and a sealing screw with an adhesive.
