The front end of the rubber air pipe 16 is connected to a suction cup 17, and the front side of the suction cup 17 extends to the front side of the adsorption groove 15.

[0023] As a technical optimization scheme of the utility model, by setting the adsorption groove 15, the rubber air tube 16 and the suction cup 17, when the front side of the rear retaining ring 2 is fitted with the side of the workpiece, the suction cup 17 is pressed toward the inside of the adsorption groove 15 by the pressure, and the air inside the rubber air tube 16 is discharged, so that negative pressure is formed inside the suction cup 17, and the side of the workpiece is adsorbed, thereby further improving the fixing effect of the rear retaining ring 2 and the side of the workpiece.

[0024] refer to Figure 1 The outer surfaces of the front retaining ring 1 and the rear retaining ring 2 are both provided with an annular groove 18, a reinforcement ring 19 is fixedly connected inside the annular groove 18, a support ring 20 is fixedly connected to the inner surface of the front retaining ring 1, and the rear side of the outer surface of the support ring 20 is fixedly connected to the inner surface of the rear retaining ring 2.

[0025] As a technical optimization scheme of the utility model, by providing an annular groove 18, providing a reinforcement ring 19 inside the annular groove 18, and providing a support ring 20 inside the front baffle ring 1 and the rear baffle ring 2, the overall strength of the front baffle ring 1 and the rear baffle ring 2 is improved, thereby avoiding the situation in which the front baffle ring 1 and the rear baffle ring 2 are deformed during use, cannot maintain a round shape, and do not fit tightly against the surface of the workpiece, causing them to fall off and affect normal use.

[0026] refer to Figure 1 and Figure 2 Four evenly distributed and interconnected circular holes 21 are provided on the surface of the front retaining ring 1 and the surface of the rear retaining ring 2. A reinforcing rib 22 is fixedly connected inside the circular hole 21.

[0027] As a technical optimization solution of the utility model, by setting a circular hole 21, setting a reinforcing rib 22 inside the circular hole 21, and setting patches 23 at both ends of the reinforcing rib 22, the tightness of the connection between the front retaining ring 1 and the rear retaining ring 2 is increased, avoiding the rear retaining ring 2 from falling off from the back of the front retaining ring 1 during use, affecting normal use.

[0029] As a technical optimization scheme of the utility model, by setting an arc plate 24, the surface curvature of the arc plate 24 is the same as the surface curvature of the front retaining ring 1, the support plate 12 can be made to support the inner wall of the workpiece more tightly, and by setting triangular grooves 25 on both sides of the arc plate 24 and convex patterns 26 on the surface, the friction when the arc plate 24 contacts the inner wall of the workpiece is increased, so that the arc plate 24 is more stable when it is in contact with the inner wall of the workpiece, and the shaking and misalignment of the arc plate 24 is avoided.

[0030] refer to Figure 1 The number of the contraction grooves 3 is eight, and the angle between two adjacent contraction grooves 3 is 45 degrees. The depth of the contraction groove 3 is the same as the distance from the bottom of the first compression spring 4 to the top of the friction ring 6 after it is fully contracted.

[0031] As a technical optimization scheme of the utility model, eight shrinkage grooves 3 are set, and the angles between adjacent shrinkage grooves 3 are the same, so that the number of friction rings 6 is increased. When the friction ring 6 is used to fix the inner wall of the workpiece, the surface of the front retaining ring 1 is evenly stressed, thereby avoiding the deformation and offset of the front retaining ring 1 due to uneven stress. By setting the depth of the shrinkage groove 3 to the distance from the bottom to the top of the friction ring 6 after the first compression spring 4 is fully contracted, the friction ring 6 can be completely retracted into the shrinkage groove 3, so that the top of the friction ring contacts the inner wall of the workpiece, thereby avoiding the situation where the front retaining ring 1 cannot be pushed into the interior of the workpiece, affecting normal use.

[0032] The working principle and use process of the utility model are as follows: by manually moving the two levers 14 to bring them closer, the moving rod 11 is driven to move inward, the support plate 12 is contracted, the outer surface of the front retaining ring 1 is fitted with the inner surface of the workpiece, and the front of the rear retaining ring 2 is fitted with the side of the workpiece, and then the lever 14 is released, the moving rod 11 is reset by the pressure of the second compression spring 10, and the support plate 12 is driven to fit with the inner surface of the workpiece. The support plate 12 supports and fixes the inner surface of the workpiece through the pressure of the second compression spring 10. At the same time, when the outer surface of the front retaining ring 1 fits with the inner surface of the workpiece, the surface of the friction ring 6 contacts the inner surface of the workpiece, so that the shrink seat 5 is moved toward the shrink groove 3. The inside shrinks, and at the same time, the rubber airbag 7 is squeezed and deformed to support the friction ring 6, so that the friction ring 6 maintains a circular shape and contacts the inner wall of the workpiece, and the contraction seat 5 is supported by the pressure of the first compression spring 4. The contraction seat 5 supports the friction ring 6, so that it applies pressure to the side close to the inner wall of the workpiece, so that the front retaining ring 1 is tightly fixed to the inner wall of the workpiece, so that the front side of the rear retaining ring 2 is fixed to the side of the workpiece to prevent it from falling off, so that the rubber retaining ring can be tightly fixed to the surface of the workpiece when in use, avoid falling off from the workpiece after long-term use, prevent the rubber retaining ring from shifting during installation, improve the operation effect of mechanical parts, and facilitate users' use.
