Description
Technical field
The utility model belongs to hardware & tools technical field, relates to a kind of screwdriver.
Background technology
Screwdriver is to be a kind ofly used for twisting screw to force its instrument in place, conventionally has a thin sphenocephaly, can insert in the line of rabbet joint or recess of screw cap.The use of screw is the earliest comparatively general, and in order to apply little torque to screw, people have expected opening a groove on head of screw, with corresponding Flathead screwdriver, just can easily tighten and unclamp screw.Along with scientific and technical develop rapidly, the application of screw is more and more extensive, and the deficiency that the flat recess of screw easily destroys is more and more obvious, and the length of flat recess is longer, also in the easier process being twisted, is destroyed.In order to shorten the length of notch, improve the ability that notch opposing destroys, can transmit onesize torsion again, people expect with cross recess, can bear same torsion, but the length of a notch short half, the ability that opposing destroys has but been strengthened greatly.Therefore at current the most common screwdriver, be exactly a word and Phillips screwdriver, other by different head dummys, can be divided into a meter word, star-like (computer), square toes, turret head, Y type head etc., as this class of installation, maintenance, all to use screwdriver, as long as can say that the place of screw will use screwdriver.Because a word and cross comparatively adopt, the screwdriver therefore having at present has a word and cross working head simultaneously.
As Chinese utility model patent application (200920252592.0) discloses a kind of multi-bit screwdriver, this kind of screwdriver comprises the cylindric screwdriver handle of end closure, there are two telescopic holes cylindric screwdriver handle lower end, in cylindric screwdriver handle, there are two springs, spring lower end is connected with a driver bit respectively, spring upper end is connected with button, and this utility model has realized a screwdriver and has been applicable to multiple screws, convenient and practical.But two telescopic holes of above-mentioned screwdriver all cannot be positioned at the shaft core position of handle of a knife simultaneously, are difficult to the application of force while causing using, and are also difficult to active force directly to pass to screw, cause screwdriver inconvenient operation.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of screwdriver, and this screwdriver has Double-cutter head, and the application of force is convenient while using.
The purpose of this utility model can realize by following technical proposal: a kind of screwdriver, the screwdriver handle that comprises a screwdriver rod and a column, it is characterized in that, the end, one end of described screwdriver rod has a word cutter head, other end end has cross cutter head, the center, end of described screwdriver handle offers a spliced eye vertically, one end sliding plug of described screwdriver rod is in spliced eye, and the relative screwdriver handle of screwdriver rod is circumferentially fixing, and between described screwdriver handle and screwdriver rod, being provided with can be by the securing keeper of screwdriver rod.
Two of screwdriver rod is respectively a word cutter head and cross cutter head, when one of them cutter head of needs, another one cutter head is inserted to the spliced eye of screwdriver handle, and fix by keeper, because the relative screwdriver handle of screwdriver rod is circumferentially fixing, therefore can transfer function power, and because spliced eye is positioned at the center of screwdriver handle, be screwdriver rod and screwdriver handle concentric, therefore can be effectively, directly by force transmission to screwdriver rod, the application of force is convenient; Because two cutter heads on screwdriver rod can be exchanged use as required, therefore use also convenient simultaneously.
In above-mentioned screwdriver, on described spliced eye inwall, offer vertically two chutes, on the two ends sidewall of described screwdriver rod, all there are two slide blocks, when screwdriver rod one end is plugged in spliced eye, the slide block of this end is slidably connected in chute.Chute can provide guide effect for screwdriver rod inserts, and chute has also carried out circumferential fixing to slide block simultaneously.
In above-mentioned screwdriver, the relative spliced eye axial line of described two chute is symmetrical arranged.The active force that when screwdriver is used, slide block is subject to is more even.
In above-mentioned screwdriver, described keeper comprises that one is connected in the magnet on spliced eye bottom surface, and described screwdriver rod adopts cast iron materials to make.Because screwdriver rod adopts cast iron materials, there is larger mechanical strength, screwdriver rod can be fixed by pump magnet adsorption after inserting spliced eye simultaneously.
In above-mentioned screwdriver, the end of described screwdriver handle is fixed with a plug, on the side of described plug, there is a column-like projection block, on described projection lateral wall, there is external screw thread, screwdriver handle end has internal thread, plug is connected on screwdriver handle by threaded engagement, and above-mentioned magnet is connected on projection end face.Plug can disassemble from screwdriver handle, therefore fixing convenient for the installation of magnet.
In above-mentioned screwdriver, on described screwdriver handle lateral wall, be fixed with a rubber layer.Increase the frictional force of screwdriver handle, feel when it is grasped is better.
Compared with prior art, this screwdriver has following advantage:
1,, because two cutter heads on screwdriver rod can be exchanged use as required, therefore use also convenient.
2, due to because the relative screwdriver handle of screwdriver rod is circumferentially fixing, and because spliced eye is positioned at the center of screwdriver handle, therefore can be effectively, directly by force transmission to screwdriver rod, the application of force is convenient.
3, owing to being fixed with a rubber layer on screwdriver handle lateral wall, therefore can increase the frictional force of screwdriver handle, feel when it is grasped is better.
Accompanying drawing explanation
Fig. 1 is the structure cutaway view of this screwdriver.
In figure, 1, screwdriver rod; 11, a word cutter head; 12, cross cutter head; 13, slide block; 2, screwdriver handle; 21, spliced eye; 22, chute; 3, magnet; 4, plug; 41, projection; 5, rubber layer.
The specific embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, a kind of screwdriver, comprises a screwdriver rod 1 and a screwdriver handle 2, and screwdriver handle 2 is column, convenient grasping.The end, one end of screwdriver rod 1 has a word cutter head 11, other end end has cross cutter head 12, the center, end of screwdriver handle 2 offers a spliced eye 21 vertically, one end sliding plug of screwdriver rod 1 is in spliced eye 21, and the relative screwdriver handle 2 of screwdriver rod 1 is circumferentially fixing, between screwdriver handle 2 and screwdriver rod 1, be provided with keeper, this keeper can be fixed on screwdriver rod 1 in the spliced eye 21 of screwdriver handle 2.When one of them cutter head of needs, another one cutter head is inserted to the spliced eye 21 of screwdriver handle 2, and fix by keeper, because the relative screwdriver handle 2 of screwdriver rod 1 is circumferentially fixing, therefore can transfer function power, and because spliced eye 21 is positioned at the center of screwdriver handle 2, i.e. screwdriver rod 1 and screwdriver handle 2 concentrics, therefore can be effectively, directly by force transmission to screwdriver rod 1, the application of force is convenient; Because two cutter heads on screwdriver rod 1 can be exchanged use as required, therefore use also convenient simultaneously.
