Description
The utility model relates to a kind of electronic screw driver.
The existing screw bottle opener is divided into manually and motor-driven two big classes.Manually screw driver is simple in structure, cost is low, but inefficiency, effort is especially when the stubborn screw of quilt is longer, more outstanding.Though motor-driven screw driver efficient height, laborsaving and can decide moment of torsion and tighten screw, but the power source of most of motor-driven screw drivers is limited by operationlocation, need connect AC power as the AC electrical screw driver, pneumatic screw driver needs power gas source, and complex structure, the cost height then is not suitable for the work of repair in short-term of arbitrary site.
The object of the present invention is to provide a kind ofly when rigging screw or knockout screw, be not subjected to workplace restriction, high efficiency, the electronic screw driver in labour-saving.
Below in conjunction with drawings and Examples the utility model is described in detail.

The utility model is by the screwdriver head retaining mechanism, screw capping (6), lock screw (7), splicing sleeve (8), planetary gear speed reducing mechanism, motor (15), sliding sleeve (11), back-moving spring (17), actuating unit, press button (16), reversing switch (23), housing (18) and four screwdriver heads are formed, the screwdriver head retaining mechanism comprises spring wire (1), steel ball (2), lock sleeve (3), locking spring (4) and swing arm (5), planetary gear speed reducing mechanism comprises tie rod plate (10), internal gear (12), planetary gear (13) and centre wheel (14), actuating unit comprises spring (20), battery case lid (21), battery (22) and bonnet (25), four screwdriver heads comprise a little word screwdriver head (26), spread-eagel screwdriver head (27), little cross driver head (28) and grand cross screwdriver head (29).
The screwdriver head retaining mechanism is used to lock screwdriver head makes it not drop out and transmit moment of torsion, swing arm in the screwdriver head retaining mechanism (5) passes with it the splicing sleeve of matched in clearance (8) and in small end and tie rod plate (10) tight fit, screw capping (6) is fixed on the head of housing (18) by three groups of uniform totally six screws (9), and this screw capping (6) is used for transmitting moment of torsion and uses when manpower is screwed.Planetary gear in the planetary gear speed reducing mechanism (13) is loaded on the tie rod plate (10), and internal gear (12) tightly fits in the sliding sleeve (11), and centre wheel (14) tightly fits on the output shaft of motor (15), to reach the function of slowing down and amplifying moment of torsion.It is that 100～300mA, rotating speed are 3000～7000 rev/mins micromachine that motor (15) adopts DC1.5V, electric current, it is loaded in the sliding sleeve (11), sliding sleeve (11) matches with housing (18) last two straight fins by two grooves on its external diameter, in sliding sleeve (11) bottom one back-moving spring (17) is housed, so that when revolving plus-pressure, swing arm (5) is gone up in the plum blossom hole of turret head size insertion screw capping (6), and when loosening pressure, turret head is deviate from again outside screw capping (6) hole.Be provided with spring (20), battery case lid (21), battery (22), contact (24) at the rear portion of housing (18), and four blind holes of storing four bottle openers are arranged, the bonnet (25) that is used for stoping four bottle openers to drop out from blind hole is tightened in the afterbody of housing (18) by screw thread.Also be provided with press button (16) and reversing switch (23) on the housing (18), they are connected to each other with motor (15) and battery (22) respectively by thin electric wire (19).
Method of operating of the present utility model: after installing battery and bottle opener, hand-held housing (18) postmedian, when rigging screw, with hand earlier 2～3 weeks of screw hand-screw in screw, screwdriver head is pressed in the head groove that is revolved screw gently, adjust reversing switch (23) to forward, pressing the button switch does not put, then screwdriver head drive screw carries out the idle stroke precession, until the screwdriver head stall, catch this moment the hand of housing (18) firmly to press down and forward rotation, make swing arm (5) go up turret head and enter in the plum blossom hole of screw capping (6), simultaneously screw is screwed.When knockout screw, must transfer to reversing switch (23) oppositely, hand-held then housing (18) housing that firmly presses down and reverse, screw is unscrewed, loosen downforce again and make the last turret head of swing arm (5) deviate from the plum blossom hole of screw capping (6), at this moment press the button switch and can make the screwdriver head counter-rotating and screw is eased out screw.In the time need using as the common manual screw driver, need only prop up swing arm (5) in upper and lower pressure shell body of certain fixture (18) and rotation, allow swing arm (5) turret head enter back lock screw (7) is tightened of screw capping (6) and get final product.Need only unscrew lock screw (7) when recovering electric functions gets final product.
Advantage of the present utility model:
1. owing to use driven by motor when sky screws in or screw out, so have the efficient than high several times of manual bolt bottle opener when screwing screw, screw is more long, and efficient improves more many, also more laborsaving.
2. not limited by the place service condition, and little power consumption, in light weight, cost is low.
3. can be used as manual screw driver usefulness, and can store four screwdriver heads, both satisfied plurality of specifications screw mounting or dismounting usefulness, be convenient to preserve screwdriver head again and carry at the housing afterbody.
