The utility model is further set to: described hinging hole side is provided with locking screw thread through hole, and described locking screw thread through hole is provided with lock(ing) bolt.
By adopting technique scheme, when securing means rotational lock bolt when using state, conflicted on the first column spinner in lock(ing) bolt one end, prevent the first column spinner in ball cage dust-proof cover working procedure because outside cause rotates, prevent that securing means in use lost efficacy.
The utility model is further set to: described elastic interface outer peripheral surface is provided with the base recess setting up for rigid base.
By adopting technique scheme, base recess has effectively guaranteed the mounting point of rigid base, has effectively improved the installation accuracy of rigid base, and after securing means is decontroled, rigid base can also frame on base recess, while preventing from unloading ball cage dust-proof cover, rigid base is lost.
The utility model is further set to: described elastic interface inner peripheral surface is provided with sealed groove, and described sealed groove is provided with seal ring.
By adopting technique scheme, sealing that seal ring has effectively guaranteed ball cage dust-proof cover, sealed groove has facilitated the installation of seal ring, has effectively guaranteed the mounting point of seal ring, prevent that seal ring from causing skew when ball cage dust-proof cover is installed, and effectively improved sealing ring tightness.
