Watch shaker, also known as automatic watch shaker or automatic watch shaker box, usually refers to a watch box equipped with a motor, which is used for automatic winding of high-grade mechanical watches. Also known as automatic winding box, automatic winding motor watch box, motor box, watch rocking box, watch rotating box and watch winding device, it refers to the watch box with a rotating dial driven by power. An automatic mechanical watch, just put on your hand, will automatically wind up with the movement of the human body, but if you take off your watch (for example, take a rest at night, or wear multiple watches in turn) for a period of time, the automatic mechanical watch will lose power and stop. The electric cabinet is a micro motor driven by battery or external power supply, which can be used to measure the insulation resistance of various motors, cables, transformers, telecommunications components, household appliances and other electrical equipment.

1, specification

2. Accuracy: 10 (equivalent to 1 of arc length). 3. Working conditions: the temperature is -25~+40℃ and the relative humidity does not exceed 80%. 4. Rated crank speed: 120 rpm. 5. Influence of external magnetic field: When the external magnetic field is 0.4kA/m, the allowable change of the instrument is 100%. 6. Tilt influence: When the instrument tilts 5 from the horizontal position to any direction, the allowable change of the instrument is 50% of the grade index. 7. Insulation resistance: The insulation resistance between all lines of the instrument and the operating room shall be no less than 20M. 8. Test voltage: The instrument can withstand sine wave AC voltage with frequency of 50Hz 1 min. Valid values of test voltage are:

9. Scale arc length: about 65mm. 10, weight: about 2kg.

Ultra-variable speed and switch control watch case. This watch case is equipped with a small rotatable dial, which is driven by a micro motor to rotate slowly, and the mechanical watch can be placed in this dial to achieve the effect of automatic winding.
