The invention discloses an adjustable containing support for bearing machining. The adjustable containing support comprises a base and a supporting plate, sliding holes are formed in the surface of the supporting plate, sliding rods are fixedly connected to the two sides of the top of the base, the tops of the sliding rods penetrate the sliding holes and extend to the exterior of the supporting plate, vertical plates are fixedly connected to the two sides of the top of the base, connecting plates are arranged in inner cavities of the vertical plates, and pull rods are fixedly connected to thesides, far away from the supporting plate, of the connecting plates. The adjustable containing support is provided with the sliding holes, the sliding rods, the vertical plates, the connecting plates,the pull rods, springs, wedge blocks, supporting blocks, sliding grooves and sliding blocks to be in cooperation, and the problem that an existing containing support for bearing machining cannot be adjusted is solved; and the adjustable containing support for bearing machining has the advantage of being adjustable, the working efficiency of a worker is improved, the working strength of the workeris reduced, use is convenient, operation is simple, use by people is facilitated, and the containing support is worthy of popularization.
