Detailed ways

The present invention will be specifically described below in conjunction with the accompanying drawings and embodiments.

Fig. 1 shows the structural representation of the present invention.

The present invention comprises a jaw support 1, a fixed jaw 2 and a movable jaw 3, the fixed jaw 2 and the movable jaw 3 are arranged oppositely and can be opened and closed.

Fig. 2 shows the structural representation of the jaw bracket and the fixed jaw of the present invention.

The jaw support 1 is a plate structure with a thickness a, and the fixed jaw 2 is fixed on the front end of the jaw support 1 .

The thickness of the fixed jaw 2 is b, and its front end is provided with a hinged hole 11.

further:

The jaw bracket 1 and the fixed jaw 2 are integrally structured, the connection is more stable, and parts and manufacturing steps are reduced at the same time.

The jaw bracket 1 is provided with a pulling end travel groove 8 parallel to the fixed jaw 2 for guiding the pulling end 6 .

At the edge of the right end of the traction end stroke groove 8 (that is, the stroke start end of the traction end 6 at the fixed jaw 2), a pull ring installation small hole 10 is provided, and a small pull ring is installed in the pull ring installation small hole 10. 9.

The small pull ring 9 is used to assist in removing the wire clamp.

For ease of use, the diameter of the small pull ring 9 is 30mm, which is convenient for the operator's fingers to enter.

The diameter of the small hole 10 for installing the pull ring is Φ2.5mm, which is enough to satisfy the flexible rotation of the small pull ring 9 in the hole.

The rear end of the fixed jaw 2 on the jaw support 1 is provided with a moving jaw stroke groove 7, and the moving jaw stroke groove 7 is inclined.

Fig. 3 is a schematic structural view of the movable jaw of the present invention.

The thickness of the movable jaw 3 is b, and the movable jaw 3 is provided with hinged hole 2 12 near the front end, and its rear end is provided with pin shaft hole 1 13 .

The front end of the movable jaw 3 is hinged with the connecting rod one 4 through the hinge hole two 12, and the rear end is placed in the movable jaw stroke groove 7 through the pin shaft hole one 13 at the rear end. The jaws of mouth 2 are parallel.

The connecting rod one 4 is a plate structure with a thickness a, and its two ends and the middle part are provided with hinged holes, one end of which is hinged with the fixed jaw 2 through the hinged hole one 11, and the connecting rod one 4 is hinged with the jaw bracket 1 after being hinged. Located on the same plane, the other end is hinged with connecting rod 25.

In order to make the jaws of the movable jaw 3 parallel to the jaws of the fixed jaw 2, the inclination of the stroke groove 7 of the movable jaw is parallel to the track where the front end of the movable jaw 3 rotates with the connecting rod 4, and the movable jaw 3 is hinged with connecting rod-4 to ensure that the movable jaw 3 is parallel to the fixed jaw 2.

Described connecting rod 2 5 is provided with two pieces, and both ends are all provided with hinged hole, and one end is positioned at connecting rod 1 4 both sides and is hinged with connecting rod 4, and the other end is positioned at the both sides of jaw support 1, and traction end 6 Hinged together and placed in the stroke groove 8 of the trailing end by the pin shaft.

The length and the starting point of the stroke groove 8 at the traction end ensure the opening and closing of the movable jaw 3 and the fixed jaw 2, that is, the inching jaw 3 and the fixed jaw 2 are closed at the initial point of the stroke groove 8 at the traction end. of.

The opposite surface of the fixed jaw 2 and the moving jaw 3 is provided with a cable groove 14, and the wire is stuck in the cable groove 14 between the moving jaw 3 and the fixed jaw 2, and is clamped into the fixed jaw smoothly with the wire. Between mouth 2 and movable jaw 3.

The cable grooves 14 of the fixed jaw 2 and the moving jaw 3 are provided with anti-slip lines, so that the wires do not slip in the moving jaw 3 and the fixed jaw 2, so that better wire tightening can be achieved.

During the operation of the present invention, the moving jaw 3 is opened and the wire is stuck in the cable groove 14 in the moving jaw 3 and the fixed jaw 2, and the moving jaw 3 is tightened by connecting the wire tightener with the traction end 6 to realize wire tightening. If the thread clamp is pushed too close, it may cause secondary tightening and sag adjustment. Push the thread clamp forward with one hand to operate it. When loosening the thread clamp, use the thumb and index finger of one hand to loosen the clamp. threader.

Working principle of the present invention: under normal circumstances, one hand can be used to push the wire clamp forward, but two hands must be operated when the wire clamp is loosened, and one hand is firmly grasped. Only by pushing the jaw 3 with one hand can the wire clamp be removed. And the pull ring installation aperture 10 of the present invention has only Φ 2.5mm, and is positioned at the edge of the beginning of stroke on the fixed jaw 2 of the trailing end 6 of the wire gripper. By changing the stroke of the trailing end 6 on the fixed jaw 2, the opening range of the movable jaw 3 is changed, so as to realize the clamping of wires with different cross-sections. When the traction end 6 is at the beginning of the stroke of the fixed jaw 2, the movable and fixed jaws of the wire gripper are completely closed. , not at the beginning of the fixed jaw stroke. In addition, the stroke of the moving jaw on the fixed jaw has also limited the traction end 6 to apply force at the beginning of the stroke of the fixed jaw 2.

The invention sets a long stroke groove, and changes the opening range of the movable jaw by changing the stroke of the traction end on the fixed jaw, so as to realize the clamping of wires with different cross-sections; The thumb and forefinger can loosen the thread clamp, which makes the operation simple and easy, and ensures the safety of the operator, brings great convenience to the thread tightening work, shortens the thread tightening time, and saves a lot of manpower, financial resources, and Material resources and construction efficiency have been effectively improved.

The above-mentioned embodiments of the present invention are just examples, not the only ones, and all changes within the scope of the present invention or equivalent to the scope of the present invention are embraced by the present invention.
