[0002] A stepper motor is an electric motor that converts electrical pulse signals into corresponding angular displacement or linear displacement. In the field of motor manufacturing, traditional stepper motors include a seat body. When the motor is connected to the lead screw, there is often a concentricity problem. At the same time, due to the large size of the motor, the motor will generate a lot of noise during use, and the noise cannot be suppressed. A fixing seat with good fixing effect is needed to fix the stepper motor to reduce shaking and noise.

[0003] The existing patent announcement number CN210074922U discloses a base of a stepper motor, including a box body, which has a hollow structure, a small circular hole is provided at the front end of the box body, and a large circular hole is provided at the rear end of the box body. A baffle plate 1 is provided at the upper end of the small circular hole, and a baffle plate 2 is provided at the upper end of the large circular hole. This fixing seat reduces the noise of the motor by setting a baffle at the front end of the motor and fixing the baffle and the fixing seat, but the fixing structure itself is not firm. At least, the shaking problem cannot be solved by a single fixation through the baffle, and some improvements are needed.

[0004] Therefore, it is necessary to design a new type of stepper motor fixing seat with strong practicality and good fixing effect. Utility Model Content

The two gears are connected to the surface of the sleeve. The rotation of the gear drives the screw fixed on one side to rotate inside the sleeve. Since the screw rotates in the original place and the surface is threadedly connected with the top plate, the surface thread rotation direction of the two screws is adapted to the displacement direction of the top plate, and the top plate is moved closer to each other through the threaded connection. Since the surface of the chassis is fixedly connected with the guide block, the top plate is slidably connected to the surface of the guide block, so the top plate clamps and fixes the two side surfaces of the stepper motor. Similarly, the gear also follows the crown gear. Rotate, the surface thread rotation direction of screw rod two is also adapted to the displacement direction of top plate two, top plate two is slidably connected with guide block two, through the threaded connection between top plate two and screw rod two, screw rod two rotates in its original position, so that top plate two squeezes the stepper motor for fixation, the corresponding surfaces of the four top plates and the stepper motor are at the same distance, and the surface of the stepper motor can be synchronously pressed against by the rotation of the screw rod. At this time, rotate the locking screw, the locking screw is connected to the internal thread of the chassis, the locking screw moves toward the inside of the chassis, and the locking screw nut presses the surface of one side of the chassis and the crown gear to stop the crown gear from rotating, thus completing the fixation of the stepper motor.
