The first fixing groove is provided with the other end of body, is hinged with the other end of the second disk body and is used cooperatively with first fixing groove
Fixed block, standing screw is connected with fixed block, nut is set with standing screw；The first disk body and the second disk body of Moving plate
On be also each provided with 1 screwed hole, the screw rod is socketed in screwed hole when using；The bolt bar is hinged on screw rod
One end on.
Preferably, the first disk body and the second disk body are overall in semi-annular shape.
Preferably, the second disk body is provided with the second fixing groove, the fixed block for installing one end of standing screw
It is hinged in the second fixing groove.
Preferably, each described screwed hole is arranged at 1/2 arc length of semi-annular shape disk body.
Preferably, being hinged as two degrees of freedom is hinged between the bolt bar and screw rod.
Beneficial effects of the present invention are：The principle of active force and reaction force according to physically power, it is oblique using object
Face circular rotating and frictional force, by easy stages fastener object cause that elbow-type end is separated, a large amount of people can be saved
Member's muscle power, can effectively shorten work of the staff when elbow-type end is dismantled and take, so that faster and better completion is robbed
Work is repaiied, the remarkable in economical benefits brought；Quiet disk and the unitary construction of Moving plate, are adapted to be used in ring main unit, branch mailbox high, effectively
Protect end, it is to avoid end is pulled bad when manpower is pullled, protect end exterior insulation.

Specific embodiment
The invention will be further described with the following Examples.
A kind of elbow-type end as Figure 1-3 pulls out the instrument of tearing open, including quiet disk 12, Moving plate 13, screw rod 3 and spiral
Handle 4.Quiet disk 12 and Moving plate 13 include the first disk body 1 and the second disk body 2, one end of the first disk body 1 and the one of the second disk body 2
End is hinged, and the first fixing groove 5 is provided with the other end of the first disk body 1, is hinged with the other end of the second disk body 2 solid with first
Determine the fixed block 6 that groove 5 is used cooperatively, the width of fixed block 6 should be slightly less than the width of the first fixing groove 5, to ensure that it is used
When can smoothly be bumped into the first fixing groove 5.Standing screw 7 is connected with fixed block 6, nut 8 is set with standing screw 7.The
One end that two disk bodies 2 are used to install standing screw 7 is provided with the second fixing groove 9, and fixed block 6 is hinged in the second fixing groove 9.Spiral shell
The external diameter of cap 8 should be greater than the width of the first fixing groove 5, and the height of fixed block 6 is substantially equivalent to the first fixing groove 5 and the second fixation
The thickness sum of groove 9, to ensure that nut 8 can play a part of screens after screwing in.
First disk body 1 and the second disk body 2 are overall in semi-annular shape, each on the first disk body 1 and the second disk body 2 of Moving plate 13
1 screwed hole 10 (see Fig. 2) is provided with, each screwed hole 10 is arranged at 1/2 arc length of semi-annular shape disk body, so can be most
Limits ground ensures to pull out center when instrument of tearing open is screwed out and does not shift, so as to ensure the stress in all directions of elbow-type end 11
It is uniform to be not easily susceptible to damage.Screw rod 3 has 2, and the first disk body 1 of Moving plate 13 and the screwed hole of the second disk body 2 are socketed in respectively
In 10, bolt bar 4 is hinged on one end of screw rod 3, being hinged as two degrees of freedom is cut with scissors between bolt bar 4 and screw rod 3
Connect, i.e., its can only along Fig. 4 arrow direction in hinge freely activity.
Fig. 3 is originally to pull out the schematic diagram when instrument of tearing open is used, and when dismounting elbow-type end 11 is needed, quiet disk 12 is sleeved on
The bottom of elbow-type end 11, while the Moving plate 13 that will screw in screw rod 3 is sleeved on the other end of elbow-type end 11, and
The end of screw rod 3 is set to be pressed on the surface of quiet disk 12, specifically suit fastening steps are as follows for quiet disk 12 and Moving plate 13：Rotate
In the fixing groove of fixed block 6 to the first 5, nut 8 is screwed in, thus quiet disk 12 and Moving plate 13 are positioned.
Position of the bolt bar 4 shown in Fig. 4 is rotated, then (can also slightly be inclined in the plane vertical with screw rod 3
Bolt bar 4 tiltedly) is rotated so as to drive screw rod 3 to rotate, Moving plate 13 is outwards screwed out under the active force of screw rod 3, and then band
Dynamic elbow-type end 11 makes it move out by easy stages, until separating.
Cable elbow head of the invention pulls out the instrument of tearing open, the principle of the active force according to physically power and reaction force, utilizes
Object inclined-plane circular rotating and frictional force, by easy stages fastener object cause that elbow-type end 11 is separated, Ke Yijie
A large amount of personnel's muscle power are saved, can effectively be shortened work of the staff when elbow-type end 11 is dismantled and be taken, so that faster more
Good completion repairing work, the remarkable in economical benefits brought；Quiet disk 12 and the unitary construction of Moving plate 13, are adapted in ring main unit, height
Used in branch mailbox, be effectively protected end, it is to avoid end is pulled bad when manpower is pullled, protect the outside of end exhausted
Edge.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than the present invention is protected
The limitation of scope is protected, although being explained to the present invention with reference to preferred embodiment, one of ordinary skill in the art should
Work as understanding, technical scheme can be modified or equivalent, without deviating from the reality of technical solution of the present invention
Matter and scope.
