[0017] Figure 1 、 2、3、4、5、6 shown, the present application based on tool cabinet body 1, is provided with transformer 3, DC power supply 4 and resistor 5 etc., plus storage box 102, drawer 103 can place various tools and components etc., with universal wheel 101 can conveniently equipment whole shift position, bring the convenience to staff test and overhaul other equipment.AC 220V power enters the power input end of power module E1, the power input end of power module E1 is powered on and its 3,4 foot will output stable DC 12V power into touch module E2 and the power input end of three sets of control circuit, when staff need to touch the first drawer 103 or the second drawer 103, third drawer 103, finger touches the first set of control circuit touch module E2 or the second set of control circuit touch module E2, third set of control circuit touch module E2 touch piece (located in the front outer end of component box), the 3 foot of the first set of control circuit touch module E2 or the second set of control circuit touch module E2, third set of control circuit touch module E2 will output high level into the positive power input end of relay K1, the relay K1 is powered on and closes its control power input end and normally open contact end, in turn, the positive and negative power input end of the motor reduction equipment M1 of the first set of driving mechanism or the second set of driving mechanism, third set of driving mechanism will be powered (at the same time, the electromagnet DC will be powered to generate suction and the rear side of the driving gear is tightly attracted together, after the rotation of the motor reduction equipment M1 of the shaft, the shaft drives the contact ring to rotate, the contact piece does not rotate, so that the contact ring 631 is powered in rotation, in turn, the motor reduction equipment M1 of the shaft of the first set of driving mechanism or the second set of driving mechanism, third set of driving mechanism drives the driving gear 62 counterclockwise, the driving gear 62 of the first set of driving mechanism or the second set of driving mechanism, third set of driving mechanism drives the straight rack 61 to move forward, the first or second, third drawer 103 is opened forward, when the first or second, third drawer 103 moves forward to the stop point (when completely open, the actual drawer rear side has 12 cm in the slide rail, plays the role of stability), the rear end magnet 8 of the first set of driving mechanism or the second set of driving mechanism, third set of driving mechanism straight rack approaches the front end dry reed S1, the internal contact of dry reed S1 is open circuit, since, one of the normally open contact ends of relay K1 is connected through dry reed S1 in series with motor reduction equipment M1 and electromagnet DC positive power input end, so, the motor reduction equipment M1 no longer drives the drawer to move forward (the electromagnet DC is powered off).When the staff needs to touch the first drawer 103 or the second drawer 103, the third drawer 103 to close, the finger touches the touch piece of the first set of control circuit touch module E2 or the second set of control circuit touch module E2, the third set of control circuit touch module E2 again, the 3-pin of the first set of control circuit touch module E2 or the second set of control circuit touch module E2, the third set of control circuit touch module E2 stops outputting high level into the positive power input end of the relay K1, the relay K1 loses power and no longer closes the control power input end and the normally closed contact end, and then the motor reduction device M1 positive and negative power input end of the first set of driving mechanism or the second set of driving mechanism, the third set of driving mechanism is powered (at the same time, the electromagnet DC is powered to generate suction and the driven gear rear side is tightly attracted together, after the motor reduction device M1 driven by the shaft rotates, the shaft drives the contact ring to rotate, and the contact piece does not rotate, so that the contact ring 631 is powered during rotation, and then the electromagnet is powered), in turn, the motor reduction device M1 shaft of the first set of driving mechanism or the second set of driving mechanism, the third set of driving mechanism drives the driving gear 62 to rotate clockwise, the driving gear 62 of the first set of driving mechanism or the second set of driving mechanism, the third set of driving mechanism drives the straight rack 61 to move backward, and the first or second, the third drawer 103 is closed backward, when the first or second, the third drawer 103 moves backward to the stop point (completely closed state), the rear end magnet 8 of the first set of driving mechanism or the second set of driving mechanism, the third set of driving mechanism straight rack approaches the rear end reed tube S2, and the reed tube S2 internal contact is open circuit, because one of the normally closed contact ends of the relay K1 is connected through the reed tube S2 in series with the motor reduction device M1 and the negative power input end of the electromagnet DC, so that the motor reduction device M1 no longer drives the drawer to move backward. Through the above, the drawer can be opened or closed by touch, which brings convenience to the staff and good experience to the staff.

[0018] Figure 1 、 2 、3、4、5、6, when the power is off, the staff needs to manually open or close the drawer (the power switch D1 can be closed to prevent sudden power-off), because the power is off, the electromagnet DC will lose power, and the electromagnet DC will be separated from the driving gear, so that when the staff pulls or pushes the drawer forward or backward, the lower end of the drawer drives the driving gear to rotate through the straight rack, and the shaft of the motor reduction device does not rotate, so that the drawer can be easily opened or closed. Through the above, the drawer can still be opened or closed when the power is off, which ensures the normal use of the equipment.

[0019] The above merely illustrates the embodiments of the present application, and is not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process conversion, or direct or indirect application in other related technical fields, which is made according to the content of the present application, shall be included in the patent protection scope of the present application.
