Wherein the motor support frame 2 and the motor 3 are fixedly connected through screws between the alignment holes.
Wherein the motor 3 and the screw rod 7 are connected in a center alignment way through the coupling 4.
Wherein the bearing support 5 and the bearing 6 are in interference fit through the hole center alignment.
Wherein the screw rod 7 is aligned and matched with the bearing 6 through the hole center.
The nut 8 is connected with the screw rod 7 in a matched mode through threads with the same specification, and the radial rotary force of the screw rod 7 is converted into the axial reciprocating force of the nut 8.
