Referring to Figures 1 to 4, the specific implementation of the live fastener provided by the embodiment of the present invention is described in detail as follows: it includes an insulating rod 3, and a two-way ratchet handle 4 is provided at the lower end of the insulating rod 3. The upper end is provided with a sleeve 1.

Compared with the prior art, the present invention is provided with a two-way ratchet handle 4 at the lower end of the insulating rod 3. During operation, the sleeve 1 is set on the bolt to be disassembled or fastened or the bolt to be installed is placed on the sleeve 1 Hold the insulating rod 3 with one hand and turn the two-way ratchet handle 4 with the other hand to easily and smoothly rotate the insulating rod 3 to remove, fasten or install the bolts, which not only solves the safety hazards of climbing and live work, but also facilitates force application , easy to operate; in addition, by turning the two-way ratchet handle 4 in the forward and reverse directions, the insulating rod 3 can be turned forward and reverse, and the bolts can be easily disassembled and tightened.

Among them, the use of insulating rod 3 for live work to fasten bolts can solve the problem of live work and reduce the time for power outage maintenance, thereby avoiding the expansion of potential accidents and the impact on the production and life of users due to power outage maintenance.

Among them, for the convenience of carrying and use, in the embodiment of the present invention, the insulating rod 3 further adopts a telescopic rod, so that the length of the insulating rod 3 can be adjusted. When not in use, the insulating rod 3 can be retracted, which is easy to carry. Adjust the length, generally 1-1.5 meters as a section, divided into multiple sections, fully stretched to about 5 meters, which can meet the needs of most high-altitude fastening bolts, for higher ones, you need to use a lifting platform or a climbing frame . Wherein, the structure of the telescopic rod is any one used in the prior art.

Further, please refer to FIG. 2 , as a specific implementation of the live fastener provided in the embodiment of the present invention, the bidirectional ratchet handle 4 includes a housing 41 , a lever 44 arranged outside the housing 41 , and a lever 44 arranged outside the housing 41 . The ratchet 42 in the 41 and the two ratchets 43 that are hinged on the inner wall of the housing 41 and are set in reverse can make the ratchet 42 reversely rotate. The lower end of the insulating rod 3 passes through the center hole of the ratchet 42 and passes through the key connect. The above is a specific implementation of the two-way ratchet handle 4 in the embodiment of the present invention. Taking FIG. 2 as an example, when the two-way ratchet handle 4 is turned clockwise, the pawl 43 on the left side moves the ratchet 42, while the right side The ratchet 43 does not work, so the ratchet 42 drives the insulating rod 3 to rotate clockwise, and then the bolt can be tightened. When turning counterclockwise, the ratchet 43 on the right side moves the ratchet 42, and the ratchet 43 on the left side If it does not work, the ratchet 42 drives the insulating rod 3 to rotate counterclockwise, then the bolt can be loosened without directly rotating the insulating rod 3 by hand. The operating space is relatively large and the force is convenient.

What needs to be explained here is that it is advisable that the two ratchets 43 are arranged symmetrically on both sides of the ratchet 42 , so that the force is more uniform and the structure is more reasonable.

The above is another specific implementation mode of the two-way ratchet handle 4 in the embodiment of the present invention. Taking Fig. 3 and Fig. 4 as examples, here the direction is reversed by turning the reversing mechanism 45 to realize the positive and negative rotation of the ratchet 42. Tighten or loosen the bolts.

Further, please refer to Fig. 3 and Fig. 4 , as a specific implementation of the live fastener provided in the embodiment of the present invention, the dial-back switching mechanism 45 includes a claw 451, a claw shaft 452, a return spring 453 and The operating knob 454, the finger 451 and the operating knob 454 are respectively arranged at the two ends of the finger shaft 452. The finger 451 is a cylindrical structure, and the outer diameter of the finger shaft 452 is smaller than that of the finger 451. 42 is radially provided with a through hole 455 with a step. The finger shaft 452 passes through the through hole 455 and can drive the finger 451 to move in the through hole 455. The return spring 453 is set on the finger shaft 452 and is limited to the finger 451 Between the shell 41 and the outer wall of the shell 41 is provided a straight groove 46 into which the operation knob 454 can be snapped. Take Figure 3 and Figure 4 as an example, when in use, when the two-way ratchet handle 4 is turned clockwise, the claw 451 will move the ratchet 42 to drive the insulating rod 3 to rotate clockwise, and then the bolt can be tightened. When the bolt needs to be loosened or removed , lift the operation knob 454 and rotate it 180 degrees. At this time, the claw 451 presses the return spring 453, so that the operation knob 454 is re-engaged in the inline groove 46, and the operation knob 454 is released, and the operation knob 454 is limited in the groove. At this time, the claw 451 is pressed against the ratchet 42 under the action of the return spring 453 , so that the claw 451 is in close contact with the ratchet 42 .

Further, please refer to FIG. 3 and FIG. 4 , as a specific implementation of the live fastener provided in the embodiment of the present invention, a vertically arranged toggle for toggling the ratchet 42 is provided at the free end of the ratchet 43 . face and has an abdication bevel on the opposite side. The toggling surface is a vertical plane and is tangent to the ratchet 42. When the two-way ratchet handle 4 is turned, the toggling surface pushes the ratchet 42 to rotate, and the abdication slope does not contact the ratchet 42; when the pawl shaft 452 rotates 180 degrees, the dial The moving surface is tangent to another adjacent ratchet 42, and under the action of force, the ratchet 42 is rotated in another direction.

Further, referring to FIG. 2 and FIG. 3 , as a specific implementation of the live fastener provided in the embodiment of the present invention, the ratchet teeth of the ratchet wheel 42 are trapezoidal teeth or rectangular teeth. The use of trapezoidal teeth or rectangular teeth is more conducive to the rotation of the ratchet 43 or the claw to push the ratchet 42 .

It can be seen from the above technical scheme that the sleeve 1 and the sleeve joint 21 are detachably connected, which can be easily replaced to suit bolts of different specifications and models. Correspondingly, a quadrangular prism hole or a hexagonal prism hole matched with the quadrangular prism or hexagonal prism can also be connected in other ways in the prior art, which will not be listed here. The cross-hinged sleeve 1 can not only rotate around the main rotating shaft 22 but also rotate around the secondary rotating shaft 23, which greatly improves the flexibility of operation. It should also be noted that the connecting head 24 and the insulating rod 3 can also be fixed by a pair of bolts, and can also be disassembled and installed.

Further, please refer to FIG. 6 , as a specific implementation of the live fastener provided in the embodiment of the present invention, a magnet 11 is provided in the sleeve 1 . Since the insulating rod 3 is extended to work at high altitudes, when the bolts are disassembled, the loose bolts are easy to fall, which will accidentally injure people, and the magnet 11 is set in the sleeve 1, and the bolts aligned with the sleeve 1 are loosened and disassembled. Finally, it can be absorbed in the sleeve 1 by the magnet 11, and when the insulating rod 3 is retracted, the bolt will not fall, avoiding the unsafe hidden danger of falling objects from high altitude.
