Specific implementation mode
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention
Formula is further described, the particular technique details hereinafter mentioned, such as：Method, equipment etc., only makes reader be better understood from
Technical solution, does not represent that present invention is limited only by following technical details.
The embodiment provides half piercings of one kind being grounded the Line tool, and as shown in Fig. 1~5, including side is to open
The rectangular box-like hanger 1 at mouthful end, the ground wire 2 being electrically connected with hanger 1, set on screw rod hanger 1 lower end and be threadedly coupled with it
3, it is set to 1 upper end inner wall of hanger set on the operating lever 4 of 3 lower end of screw rod, the horizontal movable block 5 for being set to 3 upper end of screw rod and level
Fixed block 6；
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 moves, 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 set on the stage body shape tooth 9 of 8 both sides of cone-shaped 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 coordinated 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 to side by side between outer cone tooth 11；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.Pass through the effect of baffle so that half piercing of the invention is grounded the Line tool when in use, and insulated wire can be in the limit of baffle
Under guiding role, the open end of frame 1 is quickly reached；And ball can also reduce frictional force, and insulated wire is avoided excessively to rub with baffle
It wipes and is destroyed；In addition, since ball is arranged using spacing, insulated wire is connected to when being slided on baffle, often passes through one
A ball, operator's hand-held bar can once jolt sense, and can determine whether that insulated wire distance is hung at this time by the sense number that jolts
The distance of frame open end, meanwhile, certain decelerating effect can also be played by jolting, and avoided insulated wire sliding too fast and sent out with movable teeth
There is stuck phenomenon in raw collision.
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 being equipped with below gag lever post with gag lever post screw-thread fit；
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 excessive, after the height that gag lever post is regulated especially in accordance with operating experience, for same type of insulation
Line, operating personnel, 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 inserted into insulated wire and is abutted with its inner lead, improve working efficiency；In addition, screw rod and movable block clearance fit, are limiting
Under the action of bar, movable block will not rotate therewith when screw rod rotates, and ensure that the correct engagement of movable teeth and fixed tooth.
Movable teeth 7 is arranged in 3X3 arrays comprising is distinguished set on three intermediate cone-shaped teeth 8 and in two row in a row
Stage body shape tooth 9 set on 8 both sides of cone-shaped tooth；Fixed tooth 10 is arranged in 3X4 arrays comprising two row inner cone teeth 12 and two row 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 5 removable threaded connection of movable block；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, to conveniently replaced movable block 5.
Fixed block 6 is fixedly connected by bolt with hanger 1, and dismounting and change can be carried out 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 embodiment of the present invention provides is grounded the Line tool, by using equipped with work
Insulated wire is clamped in the movable block 5 of moving teeth 7 and fixed block 6 equipped with fixed tooth 10, can puncture the insulation outside insulated wire
Layer is realized the energization to insulated wire and is grounded by ground wire 2.Since 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, 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 by cone-shaped tooth 8
When being clamped with inner cone tooth 12, insulated wire outer layer is easily punctured, but under the position-limiting action of stage body shape tooth 9, cone-shaped tooth 8 and 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 in by the open end of hanger 1 between movable block 5 and fixed block 6, by rotating behaviour
Make bar 4 so that screw rod 3 is rotated and moved up relative to hanger 1, the movable block 5 to be set to 3 upper end of screw rod is drawn close to fixed block 6,
Until the cone-shaped tooth 8 on movable block 5 and the inner cone tooth 12 on fixed block 6, which are inserted into inside insulated wire, can be realized energization ground connection.
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；Ground connection the Line tool of different model is may also set up,
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 need according to the insulated wire of different thicknesses carry out respective design, can also be tested by limited number of time
It obtains, is repeated no more in the present embodiment.
The foregoing is merely a prefered embodiment of the invention, is not intended to limit the invention, all in the spirit and principles in the present invention
Within, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
