Description

Manipulator screwdriver

Technical field

The utility model relates to a kind of screw handling instrument fields, more particularly to a kind of manipulator screwdriver.

Background technique

The cutter head of existing screwdriver in spite of the magnet for being mounted with to have certain attraction, but the magnet on cutter head is to spiral shell The adsorption capacity of nail is unable to the screw that absolute guarantee is disassembled and does not fall off with cutter head, and for example screw can be direct when encountering other object It falls off or deviates the magnet positions on cutter head and leave cutter head, that is to say, that screw often occur in the work of operation screwdriver With cutter head obscission, screw is fallen into room machine equipment under normal circumstances or ground can be found to operator and add for this Certain workload, but the equipment of such as jet engine, internal combustion engine airtightness special construction is after falling into the objects such as screw It is not only difficult to find, nor easily takes out, cause the accident of fatal crass often to send out because of foreign matter in jet engine, internal combustion engine It is raw.

Utility model content

The purpose of this utility model is to overcome deficiency in the prior art, provide a kind of structure is simple, manufacture is easy, It is easy to operate and have to screw and do not fall off the manipulator screwdriver of function promptly.

To achieve the above object, it includes knife handle and cutter hub, the cutter hub that the utility model, which provides a kind of manipulator screwdriver, Including knife bar and cutter head；Screw, that is, screw is the tool for fastening implements parts, and screw includes nut and screw rod, have on nut with Cutter head opposite groove is socketed with spring and casing on the knife bar, and casing is provided with lever, tube body and pullover；The pipe Body is hollow circular-tube, and the internal diameter of tube body is greater than the outer diameter of knife bar, and the upper end two sides of tube body, which are respectively perpendicular, is fixed with a size phase Same lever, the lower end of tube body is fixed with pullover；

The pullover is provided with arc pressuring plate, sleeve and bottom plate, and the side of the sleeve is provided with flat with tube body axis Capable opening, the internal diameter and outer diameter of sleeve are equal with the internal diameter of tube body and outer diameter difference；The upper end of the sleeve is relative to opening Side be fixedly connected with arc pressuring plate, the radian of arc pressuring plate is 180 °, under the upper end and tube body of arc pressuring plate End is fixedly connected；Bottom of the pipe is fixed with the circular bottom plate equal with pipe diameter, central point the opening to sleeve lower end of bottom plate Open slot is provided at mouthful.

The height of the sleeve is greater than or equal to the height of nut, and the height of arc pressuring plate is greater than the height of nut, opens Mouth diameter equal with the width of open slot and being all larger than screw rod.

The utility model beneficial effect is: the manipulator screwdriver structure of the utility model is simple, and manufacture is easy；Dismantle spiral shell Nail Shi Xianyong screwdriver can make in screw cap imbedded pullover after screw and fixated body are directly rotated several circles counterclockwise and knife Head is pressed on nut so that nut is tightly held between the bottom plate under cutter head and pullover very much, not only convenient disassembly, and And the nut on screw is extruded on cutter head by the bottom plate under pullover so that screw is not easy to separate with cutter head, that is, realizes screwdriver In knockout screw nut is pressed in pullover by cutter head and is fixed well, avoids screw and be easy in disassembly The drawbacks of falling；First fall into nut in pullover and with after cutter head clamping nut along opening and open slot screw rod when mounting screw Screw can be allowed to fix after rotating clockwise several circles, then directly be tightened with screwdriver, therefore because nut is by knife when mounting screw Bottom plate under head and pullover mutually compresses and not easily to fall off.

The manipulator screwdriver of the utility model is described further with reference to the accompanying drawing.

Specific embodiment

As shown in Fig. 1, Fig. 4 and Fig. 5, the manipulator screwdriver of the present embodiment includes knife handle 1 and cutter hub, and cutter hub includes knife bar 2 and cutter head 3；Screw, that is, screw is the tool for fastening implements parts, and screw includes nut 4 and screw rod 5, is had on nut 4 and knife First 3 opposite grooves are socketed with spring 6 and casing 7 on knife bar 2.The height of sleeve 12 is greater than or equal to the height of nut 4, arc The height of shape connecting plate 11 is greater than the height of nut 4, and opening 14 is equal with the width of open slot 15 and is all larger than the straight of screw rod 5 Diameter.

As shown in Fig. 2, casing 7 is provided with lever 8, tube body 9 and pullover 10；Tube body 9 be hollow circular-tube, tube body 9 it is interior Diameter is greater than the outer diameter of knife bar 2, and the upper end two sides of tube body 9, which are respectively perpendicular, is fixed with the identical lever 8 of a size, tube body 9 Lower end is fixed with pullover 10.

As shown in figure 3, pullover 10 is provided with arc pressuring plate 11, sleeve 12 and bottom plate 13, the side of sleeve 12 is provided with The opening 14 parallel with 9 axis of tube body, the internal diameter and outer diameter of sleeve 12 are equal with the internal diameter of tube body 9 and outer diameter difference；Sleeve 12 Upper end be fixedly connected relative to the side of opening 14 with arc pressuring plate 11, the radian of arc pressuring plate 11 is 180 °, arc The upper end of connecting plate 11 is fixedly connected with the lower end of tube body 9；9 lower end of tube body is fixed with the circular bottom plate equal with 9 diameter of tube body 13, open slot 15 is provided at the central point to the opening 14 of 12 lower end of sleeve of bottom plate 13.

When screw is dismantled from fixed object, first screw and fixed object are unclamped to exposing fixation 10 upper opening 14 of pullover is directed at screw rod 5 again when 5 height of screw rod of body is greater than the height of sleeve 12 and nut 4 is placed in sleeve 12 It is interior, then then the index finger of hand can be used to push down 1 upper end of knife handle, little finger and nothing the groove on nut 4 for 3 pairs of the cutter head of screwdriver Name refers to that the lever 8 for holding the upper end two sides of tube body 9 respectively, thumb and middle finger rotate counterclockwise knife in 1 two sides of knife handle Handle 1 can disassemble screw from fixation.Because the nut 4 of screw is pressed in sleeve 12 by cutter head 3, screw rod 5 is also consolidated It is scheduled in the open slot 15 of bottom plate 13, so the nut 4 in the process screw that screw is disassembled is always positioned in pullover 10 and quilt Cutter head 3 compresses, and separates the phenomenon that falling off with screwdriver to efficiently avoid screw.

First nut 4 is set to fall into pullover 10 and be pressed with cutter head 3 along opening 14 and open slot 15 screw rod 5 when mounting screw Screw can be allowed to fix after rotating clockwise several circles after tight nut 4, then directly be tightened with screwdriver, thus when mounting screw because Nut 4 is compacted by 13 up and down direction of bottom plate under cutter head 3 and pullover 10, thus eliminate screw and screwdriver during installation by Separated phenomenon occurs.
