Novel structure of sliding block of stepping motor

The utility model discloses a novel structure of a stepping motor sliding block, which comprises a bracket and a cushion block, the inner wall of the cushion block is rotatably connected with a screw rod through a ball, the tail end of the left side of the screw rod penetrates through the left part of the bracket, the outer wall of the screw rod is in threaded connection with the sliding block, and the two sides of a compression spring are respectively and fixedly connected with the sliding block and the bracket. According to the novel structure of the sliding block of the stepping motor, the sliding block, the screw rod, the compression spring, the bracket and the fully-wrapped internal threads are matched, the structure of the compression spring is adopted, and 10-20 gf pressure is applied to the sliding block, so that thread meshing teeth of the sliding block and the screw rod are in a zero-clearance state, and the displacement precision of a product is improved; according to the technical scheme, the prob
