[0022] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] The utility model anti-falling tool pliers refers to Figure 1-Figure 2 As shown, the pliers head 10 and the pliers handle 20 are movably connected by a rotating shaft 30. The end of the pliers handle 20 away from the pliers head 10 is provided with a through hole 40, and the opening direction of the through hole 40 is consistent with the moving direction of the pliers handle 20. When the present solution is used, the through hole 40 is directly opened on the pliers handle 20, and it is ensured that the opening direction of the through hole 40 is consistent with the moving direction of the pliers handle 20. After the safety rope is connected, the staff can move the pliers handle 20 to drive the pliers head 10 to work through the rotating shaft 30 to achieve the operation. Through the above-mentioned setting, the present solution directly opens a hole on the pliers body 201, and no other components need to be welded externally, which not only reduces the processing cost and processing difficulty, but also avoids the safety accidents caused by the external connection components falling off. At the same time, the opening direction of the through hole 40 is consistent with the moving direction of the pliers handle 20, which also prevents the staff from interfering with the safety rope and entanglement when using the tool pliers, thereby improving the convenience of work and accelerating the work efficiency.

[0024] As a preferred embodiment of the utility model, it may also have the following additional technical features:

[0025] In this embodiment, refer to Figure 1-Figure 2 As shown, the distance between the edge of the through hole 40 away from the pliers head 10 and the end of the pliers handle 20 is D1, and the length of D1 is 8 to 10 mm. Through the above arrangement, not only is a wear margin provided for the connection between the through hole 40 and the safety rope, but also when the tool pliers are accidentally out of hand, the end margin can bear the weight of the tool pliers and tear off the safety rope to fall from a high altitude to cause a safety accident. In this embodiment, 8 mm is preferably used as the margin length. In other embodiments, the length of D1 can be adjusted and set according to the actual weight of the tool pliers and the difficulty of processing, and is not limited to this.

[0026] In this embodiment, refer to Figure 1-Figure 2 As shown, the pliers head 10 and the pliers handle 20 are both provided with two, and are movably connected by the rotating shaft 30, and the ends of the two pliers handles 20 away from the pliers head 10 are provided with through holes 40. The design that both pliers handles 20 are provided with through holes 40 makes it easier for workers to connect the safety rope with the through hole 40 on any one of the pliers handles 20; and when one of the through holes 40 is severely worn, it can be connected with the other through hole 40, without the need to replace the tool pliers, thereby reducing the cost of work and use.

[0027] In combination with the above-mentioned configuration that both the two clamp handles 20 have through holes 40, Figure 1As shown, the opening positions of the through holes 40 on the two pliers handles 20 are consistent. Through this symmetrical arrangement, the worker can maintain a consistent feel for the tool pliers after connecting any through hole 40, avoiding problems such as affecting the worker's feel for the tool pliers due to connecting different through holes 40, causing operational difficulties, etc. In other embodiments, the positions of the through holes 40 on the two pliers handles 20 can also be inconsistent, so that the worker can connect the safety rope to the through holes 40 at different positions according to their own needs, and the adaptability is wider, and is not limited to this.

[0028] In this embodiment, refer to Figure 1 As shown, the cross-sectional shape of the through hole 40 is adapted to the cross-sectional shape of the safety rope, and the cross-sectional area is larger than the cross-sectional area of ​​the safety rope. Through the above arrangement, it can be ensured that the safety rope can smoothly pass through the through hole 40; and the cross-sectional area of ​​the through hole 40 is only slightly larger than the cross-sectional area of ​​the safety rope, which can ensure that the safety rope will not be too loose and swing after passing through, avoiding affecting the use of the staff and loosening to cause safety accidents.

[0029] In this embodiment, refer to Figure 1-Figure 2 As shown, the pliers handle 20 comprises a pliers body 201 and a gripping piece 202. The pliers body 201 and the pliers head 10 are movably linked via a rotating shaft 30. The gripping piece 202 is sleeved on the pliers body 201. The through hole 40 is provided on the end of the gripping piece 202 away from the pliers head 10. Through the above arrangement, the gripping piece 202 is sleeved on the outside of the pliers body 201 of the pliers handle 20, which improves the hand feeling of the staff in holding the pliers handle 20. Meanwhile, the pliers body 201 is usually made of metal. In this embodiment, the through hole 40 is directly provided on the gripping piece, and there is no need to open a hole on the pliers body 201, which further reduces the difficulty of opening the through hole 40 and reduces the processing cost.

[0030] Combined with the above-mentioned setting of the handshake member 202, refer to Figure 2 As shown, the distance between the edge of the through hole 40 away from the pliers head 10 and the end of the gripping piece 202 is D3, and the length of D3 is 8 to 10 mm. Similarly, through the above arrangement, not only is a wear margin provided for the connection between the through hole 40 and the safety rope, but also when the tool pliers are accidentally out of hand, the end margin can bear the weight of the tool pliers and tear off the safety rope to fall from a high altitude to cause a safety accident. In this embodiment, 8 mm is preferably used as the margin length. In other embodiments, the length of D3 can be adjusted and set according to the actual weight of the tool pliers and the difficulty of processing, and is not limited to this.

[0031] In combination with the above setting of the grip piece 202, the grip piece 202 is made of PP or ABS. The grip piece 202 made of these two materials can not only improve the grip feel of the handle and play a role in anti-slip, but also the material is easy to open and easy to process; finally and most importantly, the two materials themselves have high toughness and wear resistance, which can avoid wear due to excessive use.

[0032] In this embodiment, refer to Figure 1-Figure 2 As shown, the pliers head 10 is also provided with a notch 50 and a wave groove 60. The notch 50 can be used to easily cut or incise the outer shell of the wire or other harder materials, while the wave groove 60 can be used to adapt to wires of different sizes and remove their outer shells, thereby achieving different work requirements.

[0033] Under the premise that no conflict occurs, those skilled in the art may freely combine and superimpose the above-mentioned additional technical features.

[0034] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
