Spiral ground stud in the soil of face, solve the problems, such as existing ground stud hammer into surface soil fix it is difficult, and using bulky
Issuable potential safety hazard and hammer carry the problem of inconvenient.
In order to achieve the above object, the utility model takes following technical scheme：
Spiral ground stud, it is characterised in that including fixed part and connecting portion, the fixed part includes screw rod and handle
Hand, the top of the screw rod are fixedly connected with the handle, and the bottom of the screw rod is fine stern structure；On the connecting portion
Provided with connecting hole, fastener is provided with the connecting hole, for dead earth line terminals.
Further, the outer surface of the screw rod is provided with flight, forms helical groove.
Further, the top of the screw rod is vertical with the middle part of the handle is fixedly connected, and forms T-shaped.
Further, the top of the screw rod is vertical with one end of the handle is fixedly connected, and forms L-shaped.
Further, the connecting hole is two, and each connecting hole is equipped with internal thread.
Further, the connecting portion includes two connecting hole pieces, and the company of an insertion is respectively provided with each connecting hole piece
Connect hole.
Further, the fastener includes bolt, nut and pad.
Further, the nut is wing nut.
Further, the aperture of the connecting hole is more than the aperture of ground wire terminal.
Further, the outer surface of the handle is provided with anti-slip veins
Further, two parallel guide rods are fixed with the adjustment seat, the sliding seat is slidably connected to described
Guide rod.
The beneficial effects of the utility model are：
Spiral ground stud of the present utility model employs the principle of similar spiral bottle opener, using rotating deep side
Method instead of the fixed form of hammer hammering, has not only saved manpower, has improved security and operating efficiency, also effectively increase
The stability of fixed part；The joint efficiency of ground wire terminal is also greatly improved using wing nut simultaneously.
Brief description of the drawings
Fig. 1 is the schematic perspective view of the utility model embodiment one；
Fig. 2 is the schematic perspective view of the utility model embodiment two；
Fig. 3 is the partial enlarged drawing at I in Fig. 2；
Fig. 4 is the enlarged drawing of the fastener working condition of the utility model embodiment two.
Reference：1 screw rod, 11 flights, 2 handles, 3 connecting holes, 4 connecting hole pieces, 5 bolts, 6 nuts.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail：
As shown in Figure 1, 2, spiral ground stud, including fixed part and connecting portion, fixed part include screw rod 1 and handle 2,
The top of screw rod 1 is fixedly connected with handle 2, and the bottom of screw rod 1 is fine stern structure, and connecting portion is provided with connecting hole 3, connection
Fastener is provided with hole 3, for dead earth line terminals.
Specifically, as shown in figure 3, the flight 11 that some circles can be welded and fixed in the outer surface of round bar of screw rod 1,
Form helical groove；Lathe process, the outer surface car external threads in round bar can also be passed through.
Preferably, as shown in Figure 1, 2, the top of screw rod 1 and the middle part vertical welding of handle 2, T-shaped is formed, so
It is easy to operating personnel to hold handle 2 to rotate, screw rod 1 is screwed in surface soil；Certainly equivalents are used as, can also
By the top of screw rod 1 and one end vertical welding of handle 2, L-shaped is formed.In order that handle 2 is easy to screw, in the outer of handle 2
Surface is provided with anti-slip veins, for example, the outer surface of handle is processed using annular knurl technique.
As shown in figure 1, connecting portion can be the shaft of screw rod 1, positioned at the top of screw rod 1, connecting hole 3 is opened in spiral shell
The top of the shaft of swing arm 1, connecting hole 3 are two, and each connecting hole 3 is equipped with internal thread, for attachment screw or bolt, will connect
Ground wire terminal is pressed on the top of the shaft of screw rod 1.
As shown in Fig. 2 connecting portion can also be the part for being fixed on screw rod 1, it is preferable that connecting portion includes two welding
Connecting hole piece 4 on the shaft top of screw rod 1, the connecting hole 3 of an insertion is respectively provided with each connecting hole piece 4.Such as Fig. 2,4 institutes
Show, fastener includes bolt 5, nut 6 and pad, and bolt 5 passes through through the connecting hole 3 of insertion and the through hole of ground wire terminal
Pad and nut 6 are pressed on terminal is grounded on connecting hole piece 4.In order to facilitate staff's Quick fastening and nut 6 is unclamped,
Operating efficiency is improved, from wing nut.
Preferably, the aperture of connecting hole 3 is more than the aperture of ground wire terminal, so easily facilitate connecting hole 3 quickly
Docked with ground wire terminal.
During using spiral ground stud, first ensure the end of a thread and grounding terminal subconductivity stable connection of ground wire, led to
It is firm to cross Crimping Pliers crimping.When operating personnel reaches operating position, the bottom of the fine stern structure of spiral ground stud is tentatively inserted
Enter in surface soil, accomplish simple fixation；Subsequent operating personnel holds handle and starts to rotate, until screwing in ground about 60cm (about
