Abstract
The utility model relates to a special screw for electric larceny prevention and a matched screw driver and belongs to the technical field of fastening or fixing components. The special screw for the electric larceny prevention comprises a screw head and a bolt with threads; the bolt is arranged below the screw head; the surface of the screw head is provided with a cross groove; a crossing position in the middle of the cross groove is provided with a projection. A matched screw driver comprises a handle and a cutter bar; one end of the cutter bar, which is far from the handle, is provided with a cross blade which is matched with the cross groove; a center of the cross blade is provided with a groove which is matched with the projection. According to the special screw for the electric larceny prevention, a common cross or slot type screw driver cannot insert into the surface groove of the screw, then a client cannot operate by himself, operation is difficult through tools such as nipper pliers, and the electric larceny prevention performance is improved.
Description
Technical field
The utility model relates to a kind of Full dog point socket set and screwdriver kit thereof of opposing electricity-stealing, and belongs to fastening or fixed component technical field.
Background technique
Screw, as standard fasteners, is widely used in the fields such as industrial and civilian, as is used for fixing machinery equipment, device and member etc.People use in large quantities screw in productive life, and the instrument that conventionally need to match for screw falls its installation or removal.Except table meter terminal box, combined connection box, metering cabinet door equipotential are equipped with seal, service entrance conductor, air-break switch, tenminal block etc. are all in opening-wide state, and table meter, line switch, tenminal block all adopt cross or a word screw in all kinds of measuring apparatuss, only need one common screw-driver can be operated, client is wiring dismounting arbitrarily, stealing operation easier is little, is difficult for finding, evidence obtaining difficulty is large.
Therefore, develop a kind of Full dog point socket set not yet occurring in the market and the special operating tool of this screw and become our problem in the urgent need to address.
Model utility content
The technical problems to be solved in the utility model is, not enough for prior art, proposes a kind of Full dog point socket set of the problem of opposing electricity-stealing can solve the on-the-spot operation of measuring apparatus time and supporting screw-driver thereof.
The utility model is that one of technological scheme of solving the problems of the technologies described above proposition is: a kind of Full dog point socket set of opposing electricity-stealing, comprise screw head and threaded screw rod, described screw rod is arranged at screw head below, described screw head surface is provided with cross groove, and described cross groove intermediate interdigitated position is provided with projection.
The utility model be solve the problems of the technologies described above proposition technological scheme two be: the matching used screw-driver of a kind of Full dog point socket set of opposing electricity-stealing, comprise handle and knife bar, described knife bar is provided with the cross blade matching with described cross groove away from handle one end, the center of described cross blade is provided with the groove matching with described projection.
The improvement of one of technique scheme is: described screw head is cylindrical body.
The improvement of one of technique scheme is: described projection is rectangular-shaped.
The improvement of one of technique scheme is: described projection is cylindrical shape.
The improvement of one of technique scheme is: described protruding end face and spiral head surface maintain an equal level.
The improvement of one of technique scheme is: described protruding end face is lower than screw head surface.
Two improvement of technique scheme is: described cross blade forms by being centered around groove four side edges around, and the cross section of described side edge is trapezoidal.
The beneficial effect that the utility model adopts technique scheme to bring is: 1) the cross groove infall due to screw head of the present utility model has increased projection, make common cross and straight screwdriver cannot insert the groove of screw head, thereby client cannot Self-operating; And because convex cross section is less, use the instruments such as needle-nose pliers to be also difficult to operation, improved the performance of opposing electricity-stealing.2) supporting Speical screwdriver is to carry out specially corresponding design according to the head groove of the Full dog point socket set of opposing electricity-stealing, and the staff of electric company can conveniently be operated Full dog point socket set; Because Speical screwdriver is provided with handle, the staff of electric company is carried out more convenient to operate laborsaving to Full dog point socket set.3) this Full dog point socket set and supporting Speical screwdriver can improve the performance of opposing electricity-stealing of measuring apparatus, make to only have the staff of electric company could be to operate, and client cannot Self-operating, the problem of opposing electricity-stealing while solving the on-the-spot operation of measuring apparatus.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the structural representation of Full dog point socket set of opposing electricity-stealing in the utility model embodiment.
Fig. 2 is that schematic diagram is looked on the right side of Fig. 1.

Fig. 4 is that schematic diagram is looked on the right side of Fig. 3.
Number in the figure is schematically as follows: 1-projection, 2-cross groove, 3-groove, 4-cross blade, 5-inclined-plane, 6-screw rod.
Embodiment
Embodiment
The Full dog point socket set of opposing electricity-stealing in the present embodiment, as depicted in figs. 1 and 2, comprises screw head and threaded screw rod 6, and screw rod 6 is arranged on screw head below.Screw head surface is provided with cross groove 2, and cross groove 2 intermediate interdigitated positions are provided with rectangular-shaped projection 1.Screw head is made cylindrical shape.The end face of rectangular-shaped projection 1 and spiral head surface maintain an equal level, and the end face of projection 1 also can be lower than spiral head surface certainly.Owing to having set up rectangular-shaped projection 1, like this, general cross or straight screwdriver cannot insert, thereby cannot screw operation screw, carry out stealing.
The matching used screw-driver of the Full dog point socket set of opposing electricity-stealing in the present embodiment, as shown in Figure 3 and Figure 4, comprise handle and knife bar, knife bar is provided with the cross blade 4 matching with cross groove 2 away from handle one end, the center of cross blade 4 is provided with and projection 1 groove matching 3, and groove 3 is square opening.Cross blade 4 forms by being centered around groove four side edges around, the cross section of side edge is trapezoidal, therefore the jointing place of four side edges is distributed with eight inclined-planes 5, every two inclined-planes that face mutually 5 form 45 degree angles, the inclined-plane 5 distributing has like this increased the area of contact of Speical screwdriver and groove 2, improve the driving torque applying to screw, made the more convenient installation and removal screw of operator.
The present embodiment can also be done following improvement: change projection 1 into cylindrical shape, correspondingly, groove 3 changes countersunk head circular hole into.
In the present embodiment, the handle of screw-driver can be made Key structure, and so not only beautiful shape, uses also more convenient.
The utility model is not limited to above-described embodiment.All employings are equal to replaces the technological scheme forming, and all drops on the protection domain of the utility model requirement.
