Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, the utility model discloses a pair of safety wire pliers, which comprises two sets of pliers bodies 1 connected in a rotating manner, wherein the two sides of the rotating joint of the pliers bodies 1 are respectively a pliers mouth 2 and a pliers handle 3. The outer side surface of one of the clamp handles 3, which is opposite to the other clamp handle 3, is provided with a wiring bolt 4 which is driven into the clamp handle 3, and then a grounding wire can be wound and fixed on the wiring bolt 4. The end of the forceps handle 3 far away from the forceps mouth 2 is also fixedly connected with an insulating handle 5 made of plastic material, and anti-skid lines are wound on the insulating handle 5.

Referring to fig. 2, a spring 6 is arranged between the opposite inner side surfaces of the two sets of forceps handles 3, and in order to realize the installation of the spring 6 between the two sets of forceps handles 3, an installation through groove 7 for installing an adjusting column 8 is arranged on the two sets of forceps handles 3 in a penetrating manner, and it is worth explaining that when the two sets of forceps mouths 2 are closed and the distance between the forceps handles 3 is minimum, the two sets of installation through grooves 7 are coaxial and are axially perpendicular to the symmetrical axes of the two sets of forceps handles 3. The installation leads to the groove 7 inner wall and is provided with helicitic texture to it all is in the regulation post 8 that the groove 7 is led to in the installation through the groove 7 to pass the installation through the groove 7 and both ends, and the adaptation is provided with helicitic texture on the circumference outer wall of regulation post 8, makes and adjusts and realizes screw-thread fit between the groove 7 is led to in post 8 and the installation.

Referring to fig. 2 and 3, simultaneously, the rotation groove 9 has all been seted up perpendicularly inwards to the one end terminal surface that the regulation post 8 was kept away from on 3 to two sets of pincers, and the rotation hole that runs through regulation post 8 is seted up to the 9 tank bottoms of rotation groove, and the rotation in rotation groove 9 is provided with the T shape post 10 that one end passed the rotation hole, and T shape post 10 is greater than the rotation hole including the cylinder diameter that is located rotation groove 9, and the cylinder diameter that passes the rotation hole is unanimous with the rotation hole, realizes rotating to peg graft. The outer wall of the T-shaped column 10 extending out of the adjusting column 8 is also provided with a thread structure, and a rotating column 11 is connected with the T-shaped column through threads of the thread structure. The diameter of the rotating column 11 is smaller than that of the adjusting column 8 and is coaxially arranged with the adjusting column 8, the end face of the rotating column 11 is in sliding contact with the end face of the adjusting column 8, and therefore the rotating column 11 is connected with the end portion of the adjusting column 8 in a coaxial rotating mode.

The end surface of the rotating column 11 far from the connected adjusting column 8 is integrally formed with a hook ring 12 for connecting the spring 6, and it should be noted that the axial direction of the hook ring 12 is parallel to the rotating axial direction of the rotary connection of the two sets of forceps bodies 1. The two ends of the spring 6 are movably hung on the hook hanging rings 12 on the two groups of rotating columns 11, so that the spring 6 can rotate in the hook hanging rings 12 when the forceps handles 3 are opened or closed while the connection with the two groups of forceps handles 3 is realized.

When the aging elastic force of the spring 6 is weakened to cause that the pulling force between the two groups of the pliers handles 3 cannot meet the requirement, an operator can extend the end parts of the pliers handles 3 by rotating the adjusting columns 8, and further adjust the adjusting columns 8 in the two groups of the pliers handles 3 to be away from each other, so that the minimum length of the spring 6 is increased, namely, the elastic force between the two groups of the pliers handles 3 is increased, the elastic force reduction caused by the aging of the spring 6 is compensated, and the safety wire pliers can still be used smoothly.

Referring to fig. 2 and 3, in addition, adjust post 8 for making the rotation that operating personnel can be swiftly convenient, offer along axially extended draw-in groove 13 on the one end circumference outer wall that two sets of regulation posts 8 kept away from each other, and draw-in groove 13 is uncovered setting on the terminal surface of adjusting 8 this ends of post, be equipped with rubber cap 14 in adjusting 8 this end overcoat simultaneously, be provided with the joint sand grip 15 that corresponds with draw-in groove 13 on rubber cap 14's the inner wall, and be provided with anti-skidding line on rubber cap 14's circumference outer wall.

The implementation principle and the beneficial effects of the embodiment are as follows: adjust the post 8 through rotating and realize adjusting the length that both ends connect respectively spring 6 on two regulation posts 8, and then make spring 6 open and shut under the same angular condition of the same length difference at two sets of pincers bodies 1, realize can increase spring 6 at the tensile length under a certain angle that opens and shuts after spring 6 is ageing, even must increase the elasticity between two sets of pincers 3, the realization compensates because the elasticity that spring 6 ages and bring descends, make this security wire pincers still can continue to use smoothly, life obtains effective extension.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
