Description
Technical field
The utility model relates to field of power tools, more specifically, relates to a kind of screwdriver.
Background technology
In the past, the known electric screwdriver being built-in with the CD-ROM drive motor possessing rotating driveshaft.The output shaft that this rotating driveshaft bears rotary driving force and makes screwdriver bit, sleeve bit first-class rotates.This screwdriver is generally configured in pistol shape, can hold spy and to carry out operation by one hand.That is, the structure of the electric screwdriver of known this electric tool disclosed in application number " 200920114918.3 ", possesses: main body, is built-in with the CD-ROM drive motor possessing rotating driveshaft in this main body; And handle portion, this handle portion is configured to relative to above-mentioned power tool body along crisscross extension.According to the electric tool formed by this way, handle portion can be held in the mode same with the mode of the pikestaff gripping pistol in use, can operate the rotation of output shaft.
On the other hand, in the electric screwdriver formed by this way, be provided with the driving switch for operating the rotary actuation of CD-ROM drive motor.Imagination with picture gripping pistol pikestaff grip this handle portion situation and by this driving switch.
Said structure is when comparing operation in narrow groove, and pikestaff portion extend into when handle portion comes to groove aperture surely and both cannot continue to stretch into, and is therefore difficult to operate at bottom portion of groove.
Based on above-mentioned defect, known have the following screwdriver changed, its structure is as structure disclosed in number of patent application " 200920257548.9 ", namely the pikestaff part of screwdriver main body and handle portion roughly claim linear to arrange (also claiming straight handle type electric screwdriver) but this structure, do not meet ergonomic designs, namely can increase sense of fatigue during operation.
Therefore license notification number " CN 202862165 U " discloses a kind of electric tool, it has handle can relative to the rotatable structure of pikestaff, therefore when general operation, rotatable handle is to position substantially vertical with pikestaff, such operation would not increase inconvenience sense, when needing operation in narrow groove, then and turning handle, make handle and pikestaff claim straight line (or roughly linearly), be convenient to pikestaff and can stretch into bottom portion of groove operation.But the rotational structure of this patent is too complicated, manufacture is inconvenient and implementation cost is higher.Therefore be necessary to provide a kind of more easy structure of manufacture realizing above-mentioned functions, and implementation cost is lower.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of screwdriver, can realize handle and rotate relative to pikestaff, therefore can realize the operation of some bottom portion of groove.
The utility model is achieved through the following technical solutions: a kind of screwdriver, comprise screwdriver body, described screwdriver body comprises first and second, described second one end is provided with steel ball holder, described steel ball holder is provided with holddown groove, in described holddown groove, steel ball is set, between described holddown groove bottom and steel ball, elastic component is set, one end of described second is fixedly installed axle, described steel ball holder center is established on the shaft, be fixedly installed cover plate on the shaft, described cover plate circumference is provided with steel ball spacing hole, described steel ball is positioned at described steel ball spacing hole, described second has arc sections with the shell of described first one end be rotationally connected.
In technique scheme, described steel ball spacing hole is provided with 6, and is evenly distributed in the circumference of described cover plate.
In technique scheme, described elastic component is spring.
The utility model has following beneficial effect: can realize handle and rotate relative to pikestaff, therefore can realize the operation of some bottom portion of groove, and structure is simple, and implementation cost is lower, is easy to promote.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail: see Fig. 1 to Fig. 5, a kind of screwdriver, comprise screwdriver body 1, described screwdriver body 1 comprises first 2 and second 3, described second 3 one end are provided with steel ball holder 30, described steel ball holder 30 is provided with holddown groove (accompanying drawing does not mark), and described holddown groove is provided with two, and the line at described holddown groove center is through the center of steel ball holder 30.The line of holddown groove and horizontal direction have certain angle (horizontal direction mentioned here refers to direction during screwdriver horizontal positioned, namely as the direction of screwdriver body 1 length in accompanying drawing 2).
In described holddown groove, arrange steel ball 31, between described holddown groove bottom and steel ball 31, arrange elastic component, described elastic component is spring, and certain described elastic component is not defined as spring, also can for having flexible elastomeric material, as elastoplast etc.
One end of described second 3 is fixedly installed axle 20, described steel ball holder 30 center is located on described axle 20, described axle 20 is fixedly installed cover plate 21, and described cover plate 21 circumference is provided with steel ball spacing hole 22, and described steel ball 31 is positioned at described steel ball spacing hole 22.Described steel ball spacing hole 22 is provided with 6, and is evenly distributed in the circumference of described cover plate 21.
Described second 3 has arc sections 33 with the shell of described first 2 one end be rotationally connected, and described arc sections 33 has the angle mark 4 for measuring first 2 and second 3 angles.When rotating for described first 2, first 2 and second 3 arc sections 33 smooth excessiveness being rotationally connected place, can not cause excessive friction.
Below for described elastomeric material for spring illustrates: when being horizontal for first 2 and second 3, now described steel ball 31 is positioned at described steel ball spacing hole 22, such first 2 and second 3 is just in fixing state, now the angle mark 4 of arc sections 33 is designated as 180 degree, when carrying out needing adjusting the angle of screwdriver body first 2 and second 3, described first 2 applying is needed to the power in rotation direction, steel ball spacing hole 22 is made to lean steel ball 31, steel ball 31 leans spring, spring-compressed, steel ball 31 skids off steel ball spacing hole 22, now can rotate first 2, rotate first 2 when described steel ball 31 to enter on described cover plate another group steel ball spacing hole (often organizing steel ball angle is 60 degree) first 2 and second 3 limited.It is 60 degree owing to often organizing steel ball angle, namely the scale estimating not turn over angle mark 4 is thought and is turned over 60 degree, namely when first 2 and second 3 forwards the scale through first group of angle mark 4 to from horizontal level, namely turning to described first 2 and second 3 is 120 degree of positions, later the like, so just can learn first 2 and second 3 angle being easily, be convenient to the operation under specific environment.
