The first cam 16 interacts with the rotating shaft 13 through the damping grease 19, so that the rubber cup 2 is decelerated in the rotating process, and the rotating process is smooth and stable. First cam 16 and second cam 17 all produce viscous resistance with the pivot 13 between, the size of this resistance is directly proportional with the rotation rate of gluing cup 2, utilizes this principle can carry out fine buffering cushioning effect to gluing cup 2 rotation process, is favorable to making to glue cup 2 rotation process more steady.

As shown in fig. 3 and 4, the pressure angle of the lift 23 of the first cam 16 is larger than the pressure angle of the return 24 of the first cam 16; the pressure angle of the lift 23 of the second cam 17 is greater than the pressure angle of the return 24 of the second cam 17. Due to the arrangement, the pressure angle of the return stroke 24 is small, so that the rotating circumferential force exerted on the rubber cup 2 by the spring in the return stroke 24 movement process of the first cam 16 by the rubber cup 2 is small, and the rubber cup 2 rotates more stably; meanwhile, the large pressure angle of the lift 23 can prevent the energy of the rubber cup 2 from passing through the next wave crest of the first cam 16, and the specific curve design ensures the stability of the rotation process and the stability of the angle positioning of the rubber cup 2.

Further, a first locking switch 11 and a second locking switch 12 are arranged on the bracket 1; the vertical part of the bracket 1 comprises a fixed section and a telescopic section connected with the fixed section, and the first locking switch 11 is arranged at the joint of the fixed section and the telescopic section; the second lock switch 12 is provided at the junction of the extension and the rotation shaft 13.
