Conjugative component comprises ectosome, ball, packing ring, spring, adjusting mother, attachment ring; Ectosome is sleeved on the outside of bull gear, has the hole at the leading section of ectosome, and ball is housed in the hole; Packing ring, spring, adjusting mother are sleeved on the output shaft of described deceleration assembly successively; The bull gear resilient engagement mode of the ectosome of described conjugative component and deceleration assembly is: attachment ring is packed in the leading section of bull gear, leading section at attachment ring has the pit that adapts with ball, and outer rib-loop sieve in having on regulating mother on rib-loop and the ectosome stated closes; Under spring action, packing ring is pressed to ball, by ball ectosome and attachment ring is combined, and spring force is used to regulate, control the size that spreads out of moment of torsion.
In described shell, rechargeable battery also is housed, be used for powering to motor.
The utility model is a kind of rechargeable electric drills of using more, and the utility model adopts the deceleration assembly, adopts planetary gear reducing mechanism, and motor large speed ratio ground is slowed down, and makes the electric drill volume little, in light weight.Also adopt conjugative component to affact on the ball by spring force, make ball combine the moment of torsion that transmits with control with gear wheel, regulate the size of adhesion by regulating mother, when the working resistance of drill bit is excessive, can make ball overcome the spring force effect, from the pit of the attachment ring of gear wheel, jump out, damage, guarantee safe in utilization to avoid drill bit or motor; By the control of the spring in conjugative component operation torque, make operation torque adjustable, also can be used as multipurposes such as bottle opener or spanner and use, enlarged the scope of application.Rechargeable battery is housed, chargeable use in shell.
In sum, the utility model electric drill has that volume is small and light, efficient is high, and is safe in utilization, multipurpose, and chargeable need not electric wire, power supply, advantage such as easy to use.The utility model is applicable to that construction and decoration and areas without electricity use.

Embodiment
As Fig. 1,2 is a kind of rechargeable many structure and profile schematic diagrames with electric drill of the utility model, comprise shell 10, in described shell 10, motor 11, deceleration assembly 20, conjugative component 30 are housed, the output shaft 28 of the front end of described deceleration assembly 20 links to each other with hammer 15, and the rear end of described deceleration assembly 20 links to each other with motor shaft 12; The ectosome 31 of conjugative component 30 and bull gear 21 resilient engagement of deceleration assembly 20.
Present embodiment adopts 2 grades of planetary gear reducing mechanisms, and described deceleration assembly 20 comprises bull gear 21, back planetary gear 22, hub disk 24, pre-planetary gear 25, shroud 27; The structure that the rear end of described deceleration assembly 20 links to each other with motor shaft 12 is: the leading section of motor shaft 12 is fixed with rear center's gear 13, (axle 23 is installed on the hub disk 24, back planetary gear 22 can around axle 23 rotations) be meshed with planetary gear 22 behind the axle that is positioned at hub disk 24 rear ends 3 on 23; The external tooth of back planetary gear 22 is meshed with the internal tooth of bull gear 21: the front end center of hub disk 24 is fixed with preceding central gear 24A, (axle 26 is installed on the shroud 27, and back planetary gear 25 can rotate around axle 26) is meshed with the pre-planetary gear 25 on the axle 26 that is positioned at shroud 27 rear ends; The external tooth of pre-planetary gear 25 is meshed with the internal tooth of bull gear 21; Front end center at shroud 27 has output shaft 28, links to each other with hammer 15.In the present embodiment, all each 3 of pre-planetary gear 25, back planetary gears 22, each is in staggered distribution by 120 ° along circumference.
