Title is formed by connecting, and the first clamp combination includes strip, lateral crimping, arc crimping, described transverse direction crimping one end
Be fixedly connected with strip, the other end is fixedly connected with arc crimping, the lower clamp symmetrical connection combined by the second clamp and
At the second clamp combination includes card slot, lateral crimping, arc crimping, and described transverse direction crimping one end and card slot are solid
Fixed connection, the other end are fixedly connected with arc crimping.
It is equipped with upper wire casing on the inside of the upper clamp plate, is equipped with inserting slot corresponding with upper wire casing on the inside of the lower clamp plate.
Upper spring and lower spring are respectively equipped in the upper wire casing and inserting slot.
The other end of the upper spring and lower spring is inconsistent with upper clamp and lower clamp respectively.
It is equipped with the multiple first trapezoidal latches on the inside of the upper clamp, is equipped with multiple and the first trapezoidal card on the inside of the lower clamp
The second trapezoidal latch that tooth matches.
The strip surface is equipped with multiple ratchets, and the strip matches with card slot.
Compared with prior art, the beneficial effects of the present invention are:
1, first latching tooth and the second latch is respectively set in the present invention on the inside of upper clamp and lower clamp, using first latching tooth and
Being used in conjunction with each other between the second latch, enable cable be placed in clamp it is intracavitary, avoid cable sliding fall off, utilize simultaneously
The compactness that strip is connect with card slot makes cable clamp intracavitary more firm, improves cable normal use in circuit
Stability；
2, the present invention pushes the movement of the second head using the first head, and then strip is promoted closely to connect with card slot
Connect, it is mobile to realize the first head of gas push and the second head, compressed spring by the first head and
The anti-effect popped into position of second head, achievees the effect that freely to control upper clamp and lower clamp connection space, keeps it suitable
For the cable of different-diameter, to expand the use scope of wire clamp, manually-operated labor intensity is reduced；
3, the present invention freely controls connection space between upper clamp and lower clamp using upper spring and the elasticity of lower spring
Size, make the contact area of cable and wire clamp increase, improve the compactness of connection, reduce a possibility that cable falls off,
And the problem of upper and lower clamp is manufactured respectively in the present invention, position damage is avoided, needs integral replacing.

Specific embodiment
The following further describes the present invention with reference to the drawings:
A kind of universal separation preventing parallel groove clamp, including upper clamp plate 1, lower clamp plate 2, bolt 3, clamp assembly, the upper folder
It is connected as one between plate 1 and lower clamp plate 2 by bolt 3, is formed between the upper clamp plate 1 and lower clamp plate 2 and clamp chamber, the folder
It is equipped with the upper clamp 4 and lower clamp 5 connected with bolt 3 together in tight chamber, 1 both ends of upper clamp plate are respectively equipped with clamp assembly,
The clamp assembly includes side wall 6, the first head, the second head in upper clamp plate 1, the first activity dress
It sets including flexible leather bag 7, gas bar 8,7 both ends of the flexibility leather bag are inconsistent with side wall 6 respectively, and middle part is equipped with gas closed at one end
Bar 8, the gas bar 8 are sheathed in the second head, and second head includes column type activity cylinder 9, compressed spring 10,
The inside on 9 top of the activity cylinder is equipped with sliding slot 11, and lower part connects compressed spring 10, and bottom is fixedly connected with 4 one end of upper clamp,
The upper clamp 4 is combined by the first clamp to be symmetrically formed by connecting, and the first clamp combination includes strip 12, lateral crimping
13, arc crimping 14,13 one end of the transverse direction crimping are fixedly connected with strip 12, and the other end and arc crimping 14 are fixed
Connection, the lower clamp 5 is combined by the second clamp to be symmetrically formed by connecting, and the second clamp combination includes card slot 15, laterally folder
Line portion 13, arc crimping 14,13 one end of the transverse direction crimping are fixedly connected with card slot 15, the other end and arc crimping 14
It is fixedly connected.
It is equipped with upper wire casing 16 on the inside of the upper clamp plate 1, is equipped on the inside of the lower clamp plate 2 corresponding offline with upper wire casing 16
Slot 17.
Upper spring 18 and lower spring 19 are respectively equipped in the upper wire casing 16 and inserting slot 17.
The other end of the upper spring 18 and lower spring 19 is inconsistent with upper clamp 4 and lower clamp 5 respectively.
