Description

A kind of hand-held driving device

Technical field

The utility model relates to a kind of tool, especially a kind of hand-held driving device.

Background technique

In order to improve efficiency, some processing class tools are all electronic, such as drilling tools, electronic mode, and operator uses Get up relatively labor-saving, working efficiency is also relatively high.

But when working as voltage instability or cannot power, electronic tool just can not normal use, will affect normal Job schedule.And its output speed of electronic tool is very fast, cannot use too fast output in some occasions, otherwise be easy It causes the accident.

Therefore people need a kind of hand tool, such as hand drill, hand screwdriver etc., these tools are all by turning Shake handle and by output device output power, still, common rocking handle be it is fixed, this results in hand drill and is storing and taking It takes inconvenient.And the rocking handle rotational plane of existing hand drill is parallel with tool body, and rocking handle holds during rotation Easily encounter handle, causes inconvenient for use.

Summary of the invention

The utility model provides a kind of hand-held driving device, and rocking handle is connected and fixed using collapsible, can be with when storage The outside dimension of diminution tool entirety, to facilitate storage and carry.

The utility model the specific technical proposal is: a kind of hand-held driving device, including shell, be set to the intracorporal drive of shell Dynamic device, output device and rocking handle, rocking handle and driving device be collapsible connection and can opposite driving device folding diminution it is hand Device overall dimension；Driving device includes intermeshing face gear and bevel gear, middle surface gear and rocking handle phase Connection, the pivot center of face gear and the rotational plane of rocking handle are perpendicular.

Rocking handle is connected with driving device, rotation crank, and driving device drives output device and then output power, and rocking handle and driving fill Be set to collapsible connection, indicate that rocking handle can be folded with respect to driving device, by folding so that the position of rocking handle stretching switch to and Shell overlaps, the downsized of such hand drill entirety, to facilitate storage and carry.Face gear is nibbled with bevel gear It closes, transmission can be turned to, the pivot center of face gear and the rotational plane to be closed the border are perpendicular, the position of such rocking handle rotation More rationally.

In view of the convenience of operation, driving device is using steering transmission, the rotational plane of rocking handle and turning for output device Shaft line is parallel.General rocking handle is in the lateral location of shell, and the position that such two hand is placed meets the force production of human body It is required that.

When hand holds the handle of shell, finger can occupy the gap between a part of rocking handle and shell, preferably, rocking handle There is an angle between the central plane of shell, and rocking handle tilts in such a way that rocking handle tail end leaves shell with respect to shell.Pass through Inclined mode avoids the finger of rocking handle rotation process and another hand from occurring so that the gap between rocking handle and shell increases Interference, at the same not will cause again driving device stretch out shell it is excessive, especially fold after, inclined mode makes the tail end of rocking handle More it is biased to shell.

Preferably, the tail end of rocking handle is connected with tailing axle, grip, the rotation axis of tailing axle and output device are equipped on tailing axle Line is perpendicular.

Preferably, bevel gear is fixedly connected with transmission shaft, end part of driving shaft is connected with out splice going splice.

Preferably, transmission outer shaft sleeve is equipped with axle sleeve, axle sleeve is in contact with shell and separates shell and transmission shaft, transmission shaft On be further fixed on the circlip for placing restrictions on transmission shaft axial position.Axle sleeve separates shell and transmission shaft, and transmission shaft is avoided to connect with shell Touching, increases the rotary resistance of transmission shaft, the circlip on transmission shaft has placed restrictions on transmission shaft, transmission shaft is avoided to move axially.

Preferably, being provided with connecting shaft in shell, face gear is placed in connecting shaft, the periphery setting of face gear There is boss, limit sleeve is provided at boss and face gear is limited by limit sleeve.Face gear is placed in connecting shaft, Position in this way between face gear and bevel gear determines that boss is matched with limit sleeve, limited to face gear, avoids Shift in position occurs for face gear and bevel gear disengages.

Preferably, being articulated connection between rocking handle and driving device, also pass through buckle knot between rocking handle and driving device Structure is fixedly connected.Rocking handle needs to drive output device by driving device, therefore when normal work, rocking handle is wanted with driving device It remains connection, folds rocking handle with respect to driving device, the outer dimension of hand drill can be reduced in this way, shaken Handle and driving device hingedly after be fixedly connected by buckle structure, such rocking handle will not be detached from driving device, guarantee hand Brace works normally.

Preferably, buckle structure includes mutually matched groove and clamping part, clamping part is set on rocking handle, and groove is set It is placed in driving device, there is the protrusion being staggered and the protrusion by being staggered to form anti-loose structure for clamping part and groove.

The beneficial effects of the utility model are: rocking handle is connected with driving device, and rotation crank, driving device driving output dress It sets and then output power, rocking handle and driving device is collapsible connection, indicate that rocking handle can be folded with respect to driving device, by folding It is folded, so that the position that rocking handle stretches out switchs to overlap with shell, the downsized of such hand drill entirety, to facilitate storage Hiding and carrying.
