Abstract
The utility model provides a first structure of fluting coiled hair screw electric screw driver, comprises a pole body. The body of rod is the cylinder, and end edge has a spacing portion under the body of rod, and spacing portion be at least two sections and uses the body of rod terminal surface centre of a circle as the circular arc body of centre of a circle setting, has the head of a style of calligraphy in the body of rod tip, and the head center is on the axial lead of the body of rod, the total radian of spacing portion is greater than 90. The utility model discloses a setting of spacing portion is not skidded in the time of effectively ensureing to use, the risk of the departure that skids when avoiding installing to effectively avoid huring operator's risk.
Description
Technical field
The utility model is related to a kind of slotted pan head screw electric screw driver header structure.
Background technology
The groove of slotted screw is open architecture, because speed is slower when being tightened by hand using flat recess bottle opener, can be normal
Tighten, but it is slow to tighten speed.But if installing using electric screw driver, there is no the situation with screw center superposition at screwdriver head center
Under, can be rotated centered on screw center while screwdriver head autobiography, outwards can throw away skidding because of centrifugal action along notch,
Disfiguring workpiece is had even to injure the danger of operator.
Utility model content
For solving above-mentioned technical problem, the utility model provides a kind of slotted pan head screw electric screw driver header structure, should
The setting by limiting section for the slotted pan head screw electric screw driver header structure, non-slip when can effectively guarantee to use, it is to avoid during installation
The risk that skidding flies out, thus be prevented effectively from the risk of injury operator.
The utility model is achieved by the following technical programs.
A kind of slotted pan head screw electric screw driver header structure that the utility model provides, including the body of rod；The described body of rod is circle
Cylinder, body of rod lower end edge limited location portion, limiting section is at least two sections circular arc bodies being arranged for the center of circle with the body of rod end face center of circle,
There is the head of yi word pattern, head center is on the axial line of the body of rod in rod end；The total radian of described limiting section is more than 90 °.
The length of described head is more than 1.5 times of body of rod end face radius of circle.
Described limiting section is symmetrical arranged with respect to the center of circle.
Described limiting section is annular solid.
The beneficial effects of the utility model are：It is by the setting of limiting section, non-slip when can effectively guarantee to use, it is to avoid
The risk that during installation, skidding flies out, thus be prevented effectively from the risk of injury operator.
Brief description
Fig. 1 is the structural representation of the first embodiment of the utility model；
Fig. 2 is the upward view in Fig. 1；
Fig. 3 is the structural representation of the utility model second embodiment.
In figure：The 11- body of rod, 12- limiting section, 13- head, 21- slotted head screw.
Specific embodiment
The technical solution of the utility model be described further below, but claimed scope be not limited to described.
A kind of slotted pan head screw electric screw driver header structure as shown in Figure 1 to Figure 3, including the body of rod 11；The described body of rod 11
For cylinder, the body of rod 11 lower end edge limited location portion 12, limiting section 12 is at least two sections with the body of rod 11 end face center of circle as the center of circle
The circular arc body of setting, has the head 13 of yi word pattern, head 13 center is on the axial line of the body of rod 11 in the body of rod 11 end；Described limit
The total radian in position portion 12 is more than 90 °.
Thus, limiting section 12 head 13 can be carried out in the position at slotted head screw 21 top effectively spacing, it is to avoid fly out,
Thus avoiding unborn slip risk and effectively improving the installation rate of slotted head screw 21.
Further, for guaranteeing the normal use of head 13, the length of described head 13 is more than the body of rod 11 end face radius of circle
1.5 times.
Furthermore, as the most preferably scheme of limiting section 12, described limiting section 12 is symmetrical arranged with respect to the center of circle.
Extreme case, limiting section 12 radian be 360 ° when, the ring-type of as one full circle, now the quantity of limiting section 12 also may be used
It is considered as unlimited multistage, and is necessarily symmetrical arranged with respect to the center of circle, pretend a kind of special and common the setting for limiting section 12
Put, described limiting section 12 is annular solid.
Embodiment 1
Using above-mentioned setting, the body of rod 11, limiting section 12, head 13 are wholely set, can be used as one by this utility model
Integral installation uses.
Embodiment 2
Using above-mentioned setting, the body of rod 11 is made up of interior bar and overcoat, and limiting section 12 and overcoat are wholely set, head 13 with interior
Bar is wholely set, and overcoat side is provided with screw, and mounting screw is run through in screw portion, screw head withstand interior bar so that interior bar and
Overcoat interfixes, can be by coat suit in the upper use of an existing word screwdriver head (i.e. interior bar) by this utility model.
