The cross open bottom of screw with cross open often not smooth enough or uniform specification.Using cross mouth spiral shell
Silk knife is when being caught in turn screw in corresponding cross open, and what the lower end cutter head of screwdriver may not be able to extremely agree with is caught in
In corresponding opening, to which screwdriver easily skids.
Invention content
The object of the present invention is to provide a kind of universal cross mouth screwdriver, it has, and versatility is relatively strong, is not easy to skid
Feature.
The technical solution adopted in the present invention is：Universal cross mouth screwdriver, including handle and top are connected the hand
Handle and the handle of a knife extended downwardly,
The lower end of the handle of a knife is equipped with 4 interior plectrums extended downwardly, interior plectrum respectively where plane by the handle of a knife
Vertical axial line, adjacent interior plectrum is mutually perpendicular to, and the equal semicircular in shape in lower end of interior plectrum, be located at approximately the same plane in
Spacing with 0.5-2mm between 2 interior plectrums；
The lower part of the handle of a knife is arranged with sleeve, which can move up and down but non-rotatable relative to the handle of a knife, and the knife
The compression spring for making the sleeve have to bottom offset trend is arranged on handle；
4 outer plectrums extended downwardly are fixed on the circumference side of the lower part of the sleeve, the lower end of outer plectrum is in half
Circle, 4 outer plectrums respectively where plane pass through the handle of a knife vertical axial line；
The outside of the sleeve is equipped with external screw thread, and is bolted with nut on the handle of a knife, and the nut and the external screw thread match.
The invention has the advantages that compared with the prior art,：Versatility is stronger.The universal cross mouth spiral shell of the present invention
The outer plectrum of silk knife can be moved up and down according to circumstances, to and it is corresponding in plectrum form 2 points of cooperations, can adapt in
The cross-shaped aperture of plurality of specifications and size, versatility are greatly improved, and are not easy to skid.
Description of the drawings
Present invention will be further explained below with reference to the attached drawings and examples：
Fig. 1 is the main view half sectional view of the universal cross mouth screwdriver of the embodiment of the present invention；
Fig. 2 is the upward view of Fig. 1.
In figure：
10, handle；
20, handle of a knife；
30, interior plectrum；
40, sleeve, 41, external screw thread；
50, compression spring；

Specific implementation mode
Embodiment is seen figure 1 and figure 2：Universal cross mouth screwdriver, including handle 10 and top are connected the handle
10 and the handle of a knife 20 that extends downwardly.
Further say：
The lower end of the handle of a knife 20 is equipped with 4 interior plectrums 30 extended downwardly, and the plane where interior plectrum 30 is respective is by being somebody's turn to do
The vertical axial line of handle of a knife 20, adjacent interior plectrum 30 are mutually perpendicular to.That is, seeing from bottom to top, 4 interior plectrums 30 are located at
0 °, 90 °, 180 ° and 270 ° phase.The equal semicircular in shape in lower end of interior plectrum 30.2 interior plectrums 30 in approximately the same plane
Between with 0.5-2mm spacing.In general, the semicircular diameter of 30 lower end of interior plectrum is no more than 2mm.
The lower part of the handle of a knife 20 is arranged with sleeve 40, which can move up and down relative to the handle of a knife 20 but can not revolve
Turn.For example, sleeve 40 is equipped with inwardly projecting positioning convex point, and it is in vertical card slot that the circumference side of handle of a knife 20, which is equipped with,
Salient point is stuck in corresponding card slot.The compression spring 50 for making the sleeve 40 have to bottom offset trend is arranged on the handle of a knife 20.
4 outer plectrums 60 extended downwardly are fixed on the circumference side of the lower part of the sleeve 40, under outer plectrum 60
Equal semicircular in shape is held, the plane where 4 outer plectrums 60 are respective passes through the vertical axial line of the handle of a knife 20.Obviously, it dials outside for 4
Respectively the plane at place and the plane at the respective place of 4 interior plectrums 30 overlap piece 60 two-by-two.In the initial state, outer plectrum 60
Lower end is located in corresponding under the lower end of plectrum 30.
The outside of the sleeve 40 is equipped with external screw thread 41, and is bolted with nut 70 on the handle of a knife 20, the nut 70 and the outer spiral shell
Line 41 matches.That is, the nut 70 can be screwed onto on the sleeve 40 simultaneously.
The application method of the present invention：It is caught in 4 interior plectrums 30 are corresponding two-by-two in the cross open of screw, and by 4
Outer plectrum 60 is also caught in corresponding cross open.User is pressed downward the handle 10, and corresponding outer plectrum 60 is upward after being pressurized
It is mobile.Once can not move, then it represents that plectrum 30 has blocked reality in corresponding.At this point, the turn nut 70, makes the sleeve 40
Position is relatively fixed, you can the normal use screwdriver.
The foregoing is merely the preferred embodiment of the present invention, are not intended to limit the scope of the invention, every utilization
Equivalent structure or equivalent flow shift made by description of the invention and accompanying drawing content is applied directly or indirectly in other correlations
Technical field, be included within the scope of the present invention.
