Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type embodiment is further described, the particular technique details hereinafter mentioned, such as: method, equipment etc. only make reader more
Good understanding technical solution, does not represent the utility model and is limited only to following technical detail.
The embodiments of the present invention provide half piercing of one kind and are grounded the Line tool, as shown in Fig. 1~5, including side
For open end rectangular box-like hanger 1, be electrically connected with hanger 1 ground line 2, be threadedly coupled set on 1 lower end of hanger and with it
Screw rod 3, the operating stick 4 set on 3 lower end of screw rod, the horizontal movable block 5 for being set to 3 upper end of screw rod and level are set in 1 upper end of hanger
The fixed block 6 of wall；
Movable block 5 and fixed block 6 are positioned opposite, and movable block 5 is between 1 lower end of fixed block 6 and hanger and by screw rod 3
3 axis direction of drives edge screw rod is mobile, and one end of 5 face fixed block 6 of movable block is equipped with multiple movable teeths 7；Movable teeth 7 includes setting
In intermediate cone-shaped tooth 8 and stage body shape tooth 9 set on cone-shaped 8 two sides of tooth；The height of teeth top of cone-shaped tooth 8 is less than or equal to platform
The height of teeth top of body shape tooth 9；
One end of 6 face movable block 5 of fixed block is equipped with the fixation tooth 10 cooperated with movable teeth 7；Fixed tooth 10 includes side by side
The outer cone tooth 11 of spacing setting and at least two inner cone teeth 12 being set between outer cone tooth 11 side by side；The height of teeth top of inner cone tooth 12 is small
In the height of teeth top of outer cone tooth 11；The tooth top of cone-shaped tooth 8 is directed toward at the tooth root between two inner cone teeth 12；Two inner cone teeth 12
Tooth top is directed toward at the tooth root between cone-shaped tooth 8 and stage body shape tooth 9.
As shown in fig. 6, fixed block, which is located at hanger open end side, is equipped with the baffle 15 being downwardly inclined；Baffle end is freely
End and separate open end setting；Plate face spacing of the baffle close to open end is embedded with the ball of multiple opposing flaps rotation connections
16.By the effect of baffle, so that half piercing of the utility model is grounded the Line tool when in use, insulated wire can be in baffle
Under limition orientation effect, the open end of frame 1 is quickly reached；And ball can also reduce frictional force, avoid insulated wire and baffle mistake
Degree rubs and is destroyed；In addition, insulated wire is connected to when sliding on baffle, every warp since ball is arranged using spacing
Cross a ball, operator's hand-held bar can once jolt sense, and by jolt feel number can determine whether at this time insulated wire away from
With a distance from hanger open end, meanwhile, certain decelerating effect can also be played by jolting, avoid insulated wire sliding it is too fast and with activity
Tooth, which collides, there is stuck phenomenon.
Movable block be located at hanger open end side equipped with fixing sleeve and pass vertically through fixing sleeve 18 and with its clearance fit
Gag lever post 17；Gag lever post lower end is equipped with screw thread, and hanger is located at the tapped through hole for being equipped with below gag lever post and being threadedly engaged with gag lever post；
Gag lever post upper end is equipped with transversal protuberance.By the effect of gag lever post and fixing sleeve, movable block adjustable height can be limited,
Movable block is avoided to rise excessively, after the height that gag lever post is regulated especially in accordance with operating experience, for same type of insulation
Line, operator, which can directly rotate screw rod to movable block, to be risen, i.e., this state when, inner cone tooth 12 and cone-shaped tooth 8
It is abutted in insertion insulated wire and with its inner lead, improves working efficiency；In addition, screw rod and movable block clearance fit, are limiting
Under the action of bar, movable block will not be rotated therewith when screw rod rotates, and ensure that the correct engagement of movable teeth and fixed tooth.
Movable teeth 7 is arranged in 3X3 array comprising is set to three cone-shaped teeth 8 of centre in a column and is distinguished in two column
Stage body shape tooth 9 set on cone-shaped 8 two sides of tooth；Fixed tooth 10 is arranged in 3X4 array comprising two column inner cone teeth 12 and two column are outer
Bore tooth 11；Cone-shaped tooth 8 is parallel with the orientation of inner cone tooth 12, and is parallel to the open end of hanger 1.
Screw rod 3 and the removable threaded connection of movable block 5；5 side of movable block is additionally provided with the adjusting rod for standing screw 3
13；Adjusting rod 13 is arranged perpendicular to screw rod 3, and adjusting rod 13 passes through the horizontal threaded bore and movable block 5 set on 5 side of movable block
It is threadedly coupled.By unscrewing adjusting rod 13, screw rod 3 can be back-outed from movable block 5, thus conveniently replaced movable block 5.
Fixed block 6 is fixedly connected by bolt with hanger 1, can carry out dismounting and change to fixed block 6 by unscrewing bolt.Gu
Determine block 6, movable block 5, fixed tooth 10 and movable teeth 7 to be all made of metal material.
It is different from the prior art, half piercing that the embodiments of the present invention provide is grounded the Line tool, by using setting
There are the movable block 5 of movable teeth 7 and the fixed block 6 equipped with fixed tooth 10 to clamp insulated wire, can puncture outside insulated wire
Insulating layer is realized the energization to insulated wire and is grounded by ground line 2.Since the height of teeth top of cone-shaped tooth 8 is less than or waits
In the height of teeth top of stage body shape tooth 9, and the height of teeth top of inner cone tooth 12 is less than the height of teeth top of outer cone tooth 11, so that insulated wire is cone-shaped
When tooth 8 and inner cone tooth 12 clamp, insulated wire outer layer is easily punctured, but under the position-limiting action of stage body shape tooth 9, cone-shaped 8 He of tooth
Inner cone tooth 12 will not be pierced into too deep in insulated wire, avoid damage to the conducting wire in insulated wire.
When in use, insulated wire is caught between movable block 5 and fixed block 6 by the open end of hanger 1, passing through rotation behaviour
Making bar 4 makes screw rod 3 rotate and move up relative to hanger 1, so that the movable block 5 for being set to 3 upper end of screw rod is drawn close to fixed block 6,
Energization ground connection can be realized up to the inner cone tooth 12 on the cone-shaped tooth 8 and fixed block 6 on movable block 5 is inserted into inside insulated wire.
Certainly, when specifically used, can judge by rule of thumb inner cone tooth 12 and cone-shaped tooth 8 whether be inserted into insulated wire and with its inner lead
It abuts, can also judge whether to be powered being grounded 2 ends connection verifying attachment；It may also set up ground connection the Line tool of different model,
Make that it is suitable for the insulated wires of different model (different thicknesses).And the earthing tool of different model, fix tooth 10 and movable teeth 7
Parameter be it is different, this needs is accordingly designed according to the insulated wire of different thicknesses, can also be tested by limited times
It obtains, is repeated no more in the present embodiment.
The above is only the preferred embodiments of the utility model, are not intended to limit the utility model, all in the utility model
Spirit and principle within, any modification, equivalent replacement, improvement and so on should be included in the protection model of the utility model
Within enclosing.
