Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] The utility model provides two technical solutions:

[0032] Figure 1-5 The first embodiment is shown: a through-type linear stepping motor, comprising a base plate 1, a slide 11 is fixed in the middle of the upper surface of the base plate 1, and limited slide grooves 13 are provided on both sides of the other end of the slide 11, and two linear grooves 14 are symmetrically provided on the upper surface of the slide 11, and a mounting plate 2 is fixed at one end of the base plate 1, and air inlet grooves 22 are provided on both sides of the middle of the mounting plate 2;

[0033] The stepper motor 3 is fixed to one side of the mounting plate 2 by bolts, and a frame 21 is fixed to the other side of the mounting plate 2. The output end of the stepper motor 3 is connected to a transmission shaft 31, and a first slot 32 is provided at the end of the transmission shaft 31;

[0034] The heat dissipation component 4 is arranged in the frame 21 of the mounting plate 2 and is used to dissipate heat for the stepper motor 3. The heat dissipation component 4 includes a connecting plate 41. Both ends of the connecting plate 41 are fixedly connected to the frame 21 by bolts. Filter plates 42 are fixed on the upper and lower sides of the connecting plate 41. The edge of the filter plate 42 fits the edge of the frame 21. The filter plate 42 plays a role in filtering dust in the air to prevent dust from entering the stepper motor 3. A fan 43 is arranged in the middle of the inner side of the connecting plate 41. A first plug is fixed in the middle of one side of the fan 43. 44, the first plug block 44 is adapted to the first slot 32, so that the stepper motor 3 can drive the fan 43 to rotate through the transmission shaft 31, and the fan 43 dissipates heat for the stepper motor 3 through the air inlet slot 22 on the mounting plate 2. A connecting shaft 45 is fixed to the other end of the fan 43, one end of the connecting shaft 45 passes through the connecting plate 41 and is movably connected to the connecting plate 41 through a bearing, a second slot 46 is provided at one end of the connecting shaft 45, and the second slot 46 is connected to the linear component 5, and the fan 43 drives the screw rod 54 on the linear component 5 to rotate through the connecting shaft 45.

[0035] The linear assembly 5 is arranged on the slide 11, and the screw rod 54 on the linear assembly 5 is connected to the heat dissipation assembly 4, which is used to convert the rotational motion of the stepper motor 3 into linear motion. The linear assembly 5 includes a movable plate 51 arranged at the other end of the slide 11. The inner sides of both ends of the bottom of the movable plate 51 are fixed with limit sliders 6. The limit sliders 6 are located in the limit slide grooves 13, which play a guiding role, so that the movable plate 51 can maintain horizontal movement on the slide 11. Both ends of one side of the movable plate 51 are connected to one side of the convex plate 12 through a telescopic rod 52. The setting of the telescopic rod 52 also plays a role. The movable plate 51 is provided with a screw rod 54, which is connected to the slider 6 and is plugged into the second slot 46 on the connecting shaft 45 through the second plug block, so that the screw rod 54 can rotate with the fan 43 to drive the slider 6 to move on the slide 11.

Slots 61 are provided at both ends of the lower surface of the slider 6. A plurality of equally spaced guide wheels 62 are movably connected inside the slot 61 through a pin. The bottom of the guide wheel 62 corresponds to the linear groove 14. The arrangement of the guide wheel 62 reduces the friction between the slider 6 and the slide 11. Extension plates 63 are fixed at both ends of the bottom of the slider 6. The arrangement of the extension plate 63 plays a guiding role, so that the slider 6 maintains linear movement on the slide 11. A plurality of equally spaced ball grooves 64 are provided on the inner side of the lower end of the extension plate 63. Balls 65 are arranged inside the ball grooves 64. The balls 65 fit against both sides of the slide 11.

[0037] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0038] When installing the device, first fix the stepper motor 3 on the mounting plate 2 by bolts, then put the fan 43 into the frame 21, and fix multiple bolts at both ends of the connecting plate 41 on the frame 21. At this time, the fan 43 is stably installed, and at the same time, the first plug 44 on the fan 43 is inserted into the first slot 32 on the transmission shaft 31, so that the stepper motor 3 can drive the fan 43 to rotate. At this time, the filter screen plate 42 on the connecting plate 41 fits with the outer wall of the frame 21, which plays a role of sealing and filtering. Then, the threaded knob 53 is turned, and the threaded knob 53 drives the movable plate 51 to move, and then drives the screw rod 54 to move, until the second plug on the screw rod 54 is inserted into the second slot 46 on the connecting shaft 45. At this time, the stepper motor 3 can drive the screw rod 54 to rotate through the fan 43, and then drive the slider 6 to move on the slide 11, and convert the rotational motion of the stepper motor 3 into linear motion. The guide wheel 62 and the ball 65 on the slider 6 play a role of reducing friction, thereby increasing the service life of the slider 6 and the slide 11.
