Abstract
The utility model relates to a screwdriver with a clamping function. The screwdriver structurally comprises a screwdriver holder, a grab handle and a screwdriver bit. Three jaws are further movably connected onto the screwdriver holder, are arrayed around the screwdriver holder to form a regular triangle and can clamp a bolt by the aid of jaw driving devices, and the jaw driving devices are respectively movably connected with the grab handle and the screwdriver holder. The bolt can be clamped by the aid of the jaws, accordingly, the screwdriver can be prevented from slipping in tightening and releasing procedures, and the work efficiency of the screwdriver can be improved. Besides, the bolt in a clamped state can be tightened and accordingly can be conveniently aligned with a threaded hole. The screwdriver has the advantages of simple structure, easiness in manufacture, attractive appearance, practicality and high efficiency.
Description
Technical field
The utility model relates to a kind of hardware & tools, particularly a kind of screwdriver with clamping function.
Background technology
Nowadays along with bolt long term exposure has suffered at air, bolt self is easy to get rusty, and people are easy to occur skidding in the time using screwdriver to carry out degree of tightness operation to this bolt, very inconvenient; And sometimes because the narrow and small of space do not allow two hands to work simultaneously, now the aligning of bolt and screwed hole just seems very difficult, just seems particularly important so design a kind of screwdriver with clamping function.
Chinese invention patent discloses a kind of screwdriver No. CN103128693A, its structure be by, combined up and down by 1 straight screwdriver and 1 Phillips screwdriver, straight screwdriver and Phillips screwdriver are isometric, by handle, knife bar and cutter head three part compositions, wherein decreased food is greater than the length sum of knife bar and cutter head, handle hollow, top has internal thread, and bottom has outer silk.While depositing at ordinary times, Phillips screwdriver is inserted in the handle of straight screwdriver and tightens, in the time that needs use Phillips screwdriver, straight screwdriver is inserted in the handle of Phillips screwdriver and tightens.Although it is more practical that this invention has two kinds of cutter heads, it in use runs into the phenomenon of skidding unavoidably, is not easy to practical operation.
Summary of the invention
The utility model technical issues that need to address are to be clamped and prevented that screwdriver from skidding, and increases work efficiency by claw; A kind of screwdriver with clamping function is provided.
For solving above-mentioned technical problem, structure of the present utility model comprises handle of a knife, lever and cutter head, on handle of a knife, be also connected with three claws, three claws are equilateral triangle and arrange centered by handle of a knife, three claws clamp by jaw driving device, and jaw driving device is flexibly connected with lever and handle of a knife respectively.
Further: described jaw driving device comprises grasping mechanism and driving mechanism, three claws are connected with respectively a grasping mechanism, and three grasping mechanisms are all connected with driving mechanism.
Further again: described grasping mechanism is made up of rotating shaft and spill spin block, rotating shaft is passed spill spin block and is fixedly connected with it, and spill spin block is connected with claw, and rotating shaft is connected with driving mechanism.
Further again: described driving mechanism is to be connected to form successively by stepper motor, connecting rod and slide block, and connecting rod is connected with stepper motor by shaft coupling, and stepper motor is arranged on the inside of lever, and slide block is flexibly connected with rotating shaft.
Adopt after said structure, the utility model not only can clamp bolt by claw, prevents that skidding from appearring in screwdriver in loosen preparation procedure, improved the operating efficiency of screwdriver; And can under the state clamping, tighten operation, be convenient to aiming at of bolt and screwed hole; And that the design also has advantages of is simple in structure, be easy to manufacture, good looking appearance, practicality and high efficiency.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 is left TV structure schematic diagram of the present utility model.
In figure: 1 is lever, 2 is handle of a knife, and 3 is cutter head, and 4 is stepper motor, and 5 is shaft coupling, and 6 is connecting rod, and 7 is slide block, and 8 is spill spin block, and 9 is rotating shaft, and 10 is claw
The specific embodiment
A kind of screwdriver with clamping function as depicted in figs. 1 and 2, structure comprises handle of a knife 2, lever 1 and cutter head 3, on handle of a knife 2, be also connected with three claws 10, three claws 10 are equilateral triangle and arrange centered by handle of a knife 2, three claws 10 clamp by jaw driving device, and jaw driving device is flexibly connected with lever 1 and handle of a knife 2 respectively.Described jaw driving device comprises grasping mechanism and driving mechanism, and three claws are connected with respectively a grasping mechanism, and three grasping mechanisms are all connected with driving mechanism.In reality because bolt is easy to get rusty, while using screwdriver to carry out degree of tightness operation, be easy to occur skidding, so the present invention drives grasping mechanism by driving mechanism, the claw 10 being connected with grasping mechanism is clamped bolt, rotate again lever 1, by cutter head 3, bolt is carried out to degree of tightness operation, greatly improved the operating efficiency of screwdriver.And can first clamp bolt in some narrow and small environment, and then bolt is aimed at, very convenient.And three claws 10 in the utility model are centered by handle of a knife 2, to be equilateral triangle to arrange, and this design has improved the promptly effect of claw greatly, very practical.
Grasping mechanism is as depicted in figs. 1 and 2 made up of rotating shaft 9 and spill spin block 8, and rotating shaft 9 is passed spill spin block 8 and is fixedly connected with it, and spill spin block 8 is connected with claw 10, and rotating shaft 9 is connected with driving mechanism.Described driving mechanism is to be connected to form successively by stepper motor 4, connecting rod 6 and slide block 7, and connecting rod 6 is connected with stepper motor 4 by shaft coupling 5, and stepper motor 4 is arranged on the inside of lever 1, and slide block 7 is flexibly connected with rotating shaft 9.The utility model is pushing away slide block 7 by stepper motor 4 and is moving back and forth along handle of a knife 2, thereby the rotating shaft 9 being connected with slide block 7 is rotated, rotate fast 8 and also can rotate under the effect of rotating shaft 9, claw can clamp or unclamp operation bolt under the drive of rotation fast 8.This design is not only simple in structure, and very practical.
The utility model not only can clamp bolt by claw in sum, prevents that skidding from appearring in screwdriver in loosen preparation procedure, improved the operating efficiency of screwdriver; And can under the state clamping, tighten operation, be convenient to aiming at of bolt and screwed hole; And that the design also has advantages of is simple in structure, be easy to manufacture, good looking appearance, practicality and high efficiency.
