Abstract
The utility model discloses a screw driver which can demount and mount a screw in an inclined mode. The screw driver comprises a handle and a screw driver rod which is fixedly connected with the handle. The screw driver rod is provided with an inclined plane screw driver head. One end of the inclined plane screw driver head is an inclined plane, and an acute angle is formed between the inclined plane and a central axis of the handle. Due to the fact that the inclined plane screw driver head is used as the screw driver head, the screw driver can be embedded in a groove of the screw in an inclined angle to demount and mount the screw, the screw driver not only can demount and mount the screw located in a narrow space, but also can tighten the loosened screw on a device without demounting the device, consequentially, installing efficiency is improved, and the application range of the screw driver is expanded.
Description
Technical field
The utility model relates to a kind of screwdriver of the dismounting screw that can tilt, particularly a kind of screwdriver of the dismounting screw that can tilt.
Background technology
Screwdriver usually is used for the dismounting screw.Fig. 1 is the structural representation of the screwdriver of prior art.As shown in Figure 1, screwdriver comprises handle and the knife bar that is fixedly linked with handle.The free end of knife bar has one with the cutter head of the groove shapes correspondence of screw.When the dismounting screw, cutter head can be with the groove tabling of screw.As long as the user just can realize the dismounting of screw along the certain orientation turning handle.
Yet existing cutter head is the plane cutter head, and when the dismounting screw, knife bar needs the contact-making surface perpendicular to screw and knife bar, so the required space of dismounting screw must be able to hold whole screwdriver down.When screw was in narrow space or is stopped by other parts, the user just can't stretch into this space with whole screwdriver, thereby can't realize directly the dismounting to this screw.In addition, for the machinery equipment that has assembled, loosening if some screws of device interior take place, owing to stopping of other parts, there are not enough spaces to hold whole screwdriver yet, therefore it is fastening directly to use this screwdriver that this screw is carried out, and will earlier mounted part be removed, and then carries out fastening, so repeatedly disassemblerassembler is just for fastening certain screw, not only waste time and energy, efficient is low, and can increase the probability that damages machinery equipment.
The utility model content
The utility model carries out in order to address the above problem, and purpose is to provide a kind of screwdriver of the dismounting screw that can tilt.
To achieve these goals, the utility model has adopted following structure:
The utility model provides a kind of screwdriver, comprises handle and the knife bar that is fixedly linked with handle, and knife bar has cutter head, it is characterized in that, cutter head is the inclined-plane cutter head.
In addition, in the above-mentioned screwdriver, such feature can also be arranged: an end of inclined-plane cutter head is the inclined-plane, and the angle that the inclined-plane becomes with the axis of handle is 10 °～80 °.
Utility model effect and effect
The screwdriver that relates to according to the utility model, because the cutter head of screwdriver is the inclined-plane cutter head, one end of this inclined-plane cutter head is the inclined-plane, the angle that this inclined-plane becomes with the axis of handle is acute angle, so screwdriver can embed in the groove of screw with the angle of inclination, and this screw is carried out dismounting, not only can realize the screw that is positioned at small space is carried out dismounting, but also loosening screw and need not dismounting equipment on can fastening apparatus, thereby improved installation effectiveness and expanded the scope of application of screwdriver.
Description of drawings
Fig. 1 is the structural representation of the screwdriver of prior art.
Fig. 2 is the structural representation of the screwdriver of the utility model embodiment one.
Fig. 3 is the structural representation of the screwdriver of the utility model embodiment two.
Fig. 4 is the structural representation of the screwdriver of the utility model embodiment three.
The specific embodiment
Below in conjunction with accompanying drawing the utility model screwdriver is described in detail.
Embodiment one
Fig. 2 is the structural representation of the screwdriver of the utility model embodiment one.
As shown in Figure 2, screwdriver 1 comprises handle 2 and the knife bar 3 that is fixedly linked with handle 2.
Wherein, an end of knife bar 3 is inclined-plane cutter head 4, and an end of inclined-plane cutter head 4 is the inclined-plane, and the angle that the inclined-plane becomes with the axis of handle is 70 °, namely, the angle that becomes with the normal of the axis of handle, inclined-plane is 20 °.The axis is vertical mutually with the normal of axis.
The effect of embodiment and effect:
The screwdriver that relates to according to the utility model, because the angle that the inclined-plane of inclined-plane cutter head becomes with the axis of handle is 70 °, so this screwdriver can embed in the groove of screw obliquely, and need not with the acting surface of screw perpendicular, thereby realize the screw that is positioned at small space is carried out dismounting.
Embodiment two
Fig. 3 is the structural representation of the screwdriver of the utility model embodiment two.
As shown in Figure 3, an end of inclined-plane cutter head 5 is the inclined-plane, and the angle that the inclined-plane becomes with the axis of handle is 20 °, namely, the angle that becomes with the normal of the axis of handle, inclined-plane is 70 °.The axis is vertical mutually with the normal of axis.Other structures of screwdriver are with embodiment one.
The effect of embodiment and effect:
The screwdriver that relates to according to the utility model, because the angle that the inclined-plane of inclined-plane cutter head becomes with the axis of handle is 20 °, so this screwdriver can stretch in the slit of mounted machinery equipment and carry out fastening to the screw that is positioned at this slit, and need not again this screw to be carried out behind the first dismounting equipment fastening, thereby improved installation effectiveness and reduced machinery equipment the wearing and tearing that produce because of frequent dismounting.
Embodiment three
Fig. 4 is the structural representation of the screwdriver of the utility model embodiment three.
As shown in Figure 4, an end of inclined-plane cutter head 6 is the inclined-plane, and the angle that the inclined-plane becomes with the axis of handle is 45 °, namely, the angle that becomes with the normal of the axis of handle, inclined-plane is 45 °.The axis is vertical mutually with the normal of axis.Other structures of screwdriver are with embodiment one.
The effect of embodiment and effect:
The screwdriver that relates to according to the utility model, because the angle that the inclined-plane of inclined-plane cutter head becomes with the axis of handle is 45 °, so this screwdriver not only can be realized the dismounting to the screw that is positioned at small space, and when dismounting and screwdriver enough frictional force is arranged, thereby can prevent skidding.
Claims (2)
1. a screwdriver comprises handle and the knife bar that is fixedly linked with described handle, and described knife bar has cutter head, it is characterized in that, described cutter head is the inclined-plane cutter head.
2. screwdriver according to claim 1 is characterized in that:
