Technical Field

[0001] The utility model relates to the technical field of slips, in particular to a slip tooth assembly device. Background Art

[0002] Slips are an important part of the packer. They play the role of supporting the packer and locking the center string when setting. The design of opening and embedding particles can increase the friction between the slips and the casing, thereby improving the reliability of anchoring.

[0003] When embedding the slip tooth particles, they are generally knocked into the hole. The force of the knocking will vary from light to heavy during manual knocking. The knocking force is small at the beginning, which is mainly used to make the rear end of the slip tooth particle accurately enter the hole. As more particles enter the hole, the particle positioning becomes more stable. At this time, the knocking force can be gradually increased to quickly embed the particles into the hole.
