Especially, for the battery of such instrument or battery reply, there is power large as far as possible, change easily or charging.But although current battery has various ways replacing with, the charging interval is still longer, particularly lack for some the operation occasion needing cannot charge for a long time, how changing battery is a considerable problem.
Summary of the invention
Based on above-mentioned deficiency, invention has been further investigation, develop a kind of electric screw driver.
One object of the present invention is, provides a kind of electric screw driver, when exhaustion of the accumulators electricity, is replaced with reserve battery easily.
The invention provides a kind of electric screw driver, comprise housing, handle, in described housing, motor is installed, described housing forward end is provided with output shaft, described output shaft is connected by transmission mechanism with described motor, and the front end of described output shaft is provided with driver bit jack, for insertion tool annex; Control unit is provided with in described handle, for the transmission/reception memory cell of signal sending/receiving, charging socket, the switch that is connected is carried out by control unit with described motor, the charging socket be connected with the batteries below described handle, by startup and the stopping of motor described in described switch control rule, it is characterized in that:
Described batteries has molding outer casing, and the battery core brace of banded structure is arranged within the framework on described molding outer casing, and described battery core brace is suitable for and the electrode electrical contact of battery of installing in batteries; Wherein a side of molding outer casing is detachable buckle-type snap-latch surface.
Preferably, described battery core brace has bending arch-shaped, makes bend outstanding to described electrode side.
Preferably, described battery core brace, at bend place, is provided with spring with the contrary side of described electrode contact.
Preferably, in bend and the described electrode contact side of described battery core brace, electrode contact plate is welded with.
Preferably, the battery closed on adopts mode in parallel directly to connect by described battery core brace is one group of sub-battery pack.
So, when dead battery capability and when can not charge in time, buckle-type snap-latch surface can be removed easily, built-in normal cell is replaced by normal cell for subsequent use, make in the occasion of being inconvenient to charge, standard size battery also can be used as reserve battery.

Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is further described, but does not limit the invention to these detailed description of the invention.One skilled in the art would recognize that all alternatives, improvement project and the equivalents that present invention encompasses and may comprise in Claims scope.
Embodiment 1
As shown in Figure 1, the invention provides a kind of electric screw driver, there is housing 1, handle 2, motor 3 is installed in housing 1, housing 1 front end is provided with output shaft 12, output shaft 12 is connected by transmission mechanism 4 with motor 3, and the front end of output shaft 12 is provided with driver bit jack, can install the driver bit 16 of different model in driver bit jack.
Control unit 19 is provided with in handle 2, for the transmission/reception 50 of signal sending/receiving, memory cell 51, charging socket 52, carries out the switch 17 that is connected, the charging socket 42 be connected with the batteries 18 below handle 2 with motor 3 by control unit 19, batteries 18 is provided with below handle 2, control motor 3 by switch 17 to start and stop, being connected with extraneous power supply by charging socket 12, can charge to batteries 18.
Preferably, it is slightly large that batteries 18 is configured to the shape after relatively multiple normal cell permutation and combination and size, as can be be a bit larger tham 8 standards No. 1 battery with 2 × the 4 vertically shape of arrangement and sizes.
Batteries 18 has molding outer casing 100, and molding outer casing 100 is suitable for holding 8 standards No. 1 battery in 2 × 4 modes vertically arranged.As accompanying drawing 2 schematically shows the form of single 4 batteries by battery core connector composition battery pack.Certainly this battery pack can arrange more or less battery, or uses other standards size battery, and electricity series connection or electric mode in parallel are connected to power bus A0 (not shown) as required.
The battery core brace 120 of banded structure is arranged within the framework 110 on molding outer casing 100, and molding outer casing 100 and framework 110 use insulating materials to make, typical in plastics or electro-insulating rubber etc.Special framework 110 can use injection molding forming method that battery core brace 120 is attached on molding outer casing 100.
Battery core brace 120 is suitable for electrode 111 electrical contact with battery.Preferred battery core brace 120 has bending arch-shaped, make bend 121 outstanding to electrode 111 side, and preferred battery core brace 120 is at bend place further, the contrary side contacted with electrode 111 is provided with spring 150, by spring pressure, the bend 121 of battery core brace 120 can be kept to maintain the original state in Reusability process.
