The technical scheme providing according to the utility model, elastic driving mechanism on motor comprises limiting plate and driver plate, it is characterized in that: limiting plate and driver plate are connected on motor output shaft, limiting plate and motor output shaft are interference fit, limiting plate top connects backing pin and steady pin, on steady pin, weld guide finger, on guide finger, connect sliding sleeve, between sliding sleeve and guide finger, be provided with buffer spring; Driver plate top is provided with the movable head linking into an integrated entity with driver plate, and movable head, between backing pin and sliding sleeve, and compresses by buffer spring; Described driver plate bottom fixed idler whell pin, is rotationally connected roller on roller pin; Described limiting plate bottom is provided with two symmetrical spacing otic placodes, between two spacing otic placodes, is provided with the stop screw being connected on motor end plate, by stop screw, limits the angle that limiting plate swings.
Further, between limiting plate and driver plate, be provided with the cushion block that limiting plate and driver plate are separated.
Further, the angular range between two spacing otic placodes is 30 ° ~ 120 °.
Further, driver plate one side is provided with adjusts pad and jump ring, adjusts pad and jump ring driver plate is pressed on motor output shaft.
Further, limiting plate is D type hole with the hole that is connected motor output shaft of setting.
Further, described motor output shaft and limiting plate junction are knurling structure.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, compact, reasonable, ensuring smooth transmission; Have limit function, machine operation is within certain angle scope, and operating angle can adjust as requested, guarantees that motor can not surpass scope work; There is buffer spring, reduce the impact that stepping motor is subject to, eliminate the gap between each parts of stepping motor parts, and can prevent motor desynchronizing under some extreme situation.

Embodiment
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Figure 1 and 2, the utility model mainly comprises limiting plate 1 and driver plate 2, and limiting plate 1 and driver plate 2 are connected on motor output shaft 3, and limiting plate 1 is annular knurl interference fit with motor output shaft 3, and limiting plate is D type hole with the hole that is connected motor output shaft of setting.Between limiting plate 1 and driver plate 2, be provided with the cushion block 4 that limiting plate 1 and driver plate 2 are separated.
As shown in Fig. 3 ~ 4, limiting plate 1 top connects backing pin 8 and steady pin 9, welds guide finger 10 on steady pin 9, connects sliding sleeve 6 on guide finger 10, between sliding sleeve 6 and guide finger 10, is provided with buffer spring 7.
As shown in Fig. 5 ~ 6, driver plate 2 tops are provided with the movable head 14 linking into an integrated entity with driver plate 2, and movable head 14, between backing pin 8 and sliding sleeve 6, and compresses by buffer spring 7.During work, limiting plate 1 is driven and is rotated by motor output shaft 3, and limiting plate 1 drives driver plate 2 to rotate by backing pin 8 and sliding sleeve 6 clamping movable heads 14 again.Buffer spring 7 can be eliminated drive gap by spring force, and the while to the transmission of the elimination in a flash impulsive force of closing, avoids the shock of driving member to damage at electric motor starting.
Described driver plate 2 bottom fixed idler whell pins 13, are rotationally connected roller 12 on roller pin 13.
The angular range that described limiting plate 1 bottom is provided with between 11, two spacing otic placodes 11 of two symmetrical spacing otic placodes is 30 ° ~ 120 °.Between two spacing otic placodes 11, be provided with the stop screw 5 being connected on motor end plate, the angle swinging by stop screw 5 restriction limiting plates 1.
Described driver plate 2 one sides are provided with adjusts pad 15 and jump ring 16, adjusts pad 15 and jump ring 16 driver plate 2 is pressed on motor output shaft 3, prevents that driver plate 2 from coming off from motor output shaft 3.
Operation principle of the present utility model is: during work, motor output shaft drives limiting plate to rotate, and limiting plate drives again the driver plate of clamping to rotate, and buffer spring can be eliminated the drive gap between each parts, and limiting plate and driver plate are compressed, and has improved transmission accuracy.Stop screw between spacing otic placode is controlled the angle that limiting plate rotates, and makes motor-driven scope flexibility and changeability.When motor output shaft stops operating, buffer spring can reduce the impact that motor return is subject to, and it is out-of-step free to make motor exceed range of movement certain angle in its corresponding direction of motion.
