Stirring efficiency.
As one of which set-up mode, the positioning limiting fixator includes mounting bracket, and the straight line being arranged on mounting bracket is slided
Moving part；The centerline axis parallel of the glide direction and swingle of the linear slide part, driving motor are fixed on the straight line
On sliding part.
Preferably, the linear slide part is sliding rail.
Further, the spiral bullet being provided between the lid and driving motor on the motor shaft for being socketed in driving motor
The top of spring, the helical spring is fixed on the shell of driving motor, and the bottom end of the helical spring is fixed on lid.Pass through
The setting of above-mentioned helical spring can preferably mitigate the power that driving motor is applied on swingle, i.e., effectively mitigate connection through-hole
Active force on upper internal thread and swingle between external screw thread reduces frictional force, while prolonging the service life, moreover it is possible to effectively section
About energy consumption reduces cost.
The utility model compared with prior art, has the following advantages and advantageous effect：
1, the utility model both can effectively realize swingle moving up in rotary course, can also realize and rotate through
Moving down in journey while stirring in the horizontal direction, is effectively increased the function of the stirring in axial direction, keeps stirring more uniform,
Improve stirring efficiency；
