[0044] The embodiments of the present invention will be described in detail below with reference to the drawings.

[0045] As Figures 1 - 3 shown, the embodiment of the present invention provides a pair of shearing pliers for emergency rescue and window breaking, which includes several parts such as a shearing pliers head 1, a pliers handle 2, and a portable part 3.

[0046] Among them, the shearing pliers head 1 includes a first shearing part 11 and a second shearing part 12. The first shearing part 11 has a first arc edge 111 and a second arc edge 112. The first arc edge 111 and the second arc edge 112 converge together at the distal end of the pliers head, and the first arc edge 111 and the second arc edge 112 are spaced apart at a preset distance at the proximal end of the pliers head. Among them, the curvature of the first arc edge 111 is greater than the curvature of the second arc edge 112. The second shearing part 12 has the same shape as the first shearing part 11 and is arranged opposite to the first shearing part 11. The first shearing part 11 and the second shearing part 12 are hinged at the proximal end of the pliers head. Specifically, in this embodiment, as Figure 1As shown, both the first shearing part 11 and the second shearing part 12 are semi-enclosed, for example, in a semi-enclosed shape of an arc. There is at least a non-zero spacing between the first shearing part 11 and the second shearing part 12. When the form is placed between the first shearing part 11 and the second shearing part 12, the cutting function of the form is realized under the cooperation of the first shearing part 11 and the second shearing part 12. In this embodiment, the arc-shaped first shearing part 11 and the second shearing part 12 change the contact between the shearing part and the form from the previous two-point contact to multiple-point contact. Under the cooperation of the first shearing part 11 and the second shearing part 12, a surrounding situation is formed for the form, greatly increasing the contact area, ensuring the stability between the shearing part and the form, and being able to more efficiently and quickly achieve the purpose of cutting the form.

[0047] The pliers handle 2 includes a first pliers handle 21 and a second pliers handle 22. The first pliers handle 21 is connected to the first shearing part 11, and the second pliers handle 22 is connected to the second shearing part 12; by controlling the first pliers handle 21 and the second pliers handle 22, the spacing between the first shearing part 11 and the second shearing part 12 is adjusted, so as to realize the function of adjusting the spacing between the first shearing part 11 and the second shearing part 12 according to the actual application scenario.

[0048] The portable part 3 is arranged on the pliers handle 2 for connecting with the safety hook of the rescuer. Its main function is to facilitate the rescuer to carry the cutting pliers. The number of the portable parts 3 can be several. More specifically, in this embodiment, the portable part 3 is a semi-circular ring part arranged on the outer side of the pliers handle 2. During use, the safety hook worn by the rescuer is connected to the semi-circular ring part, and the cutting pliers are hung on the waist of the rescuer through the semi-circular ring part, realizing the synchronous movement of the cutting pliers and the rescuer, and avoiding the situation that the rescuer holds the cutting pliers and moves.

[0049] In order to further facilitate the rescuer to carry the cutting pliers. The pliers handle 2 in this embodiment is set as a telescopic structure. The telescopic pliers handle includes a fixed part 211 and a movable part 212 whose outer dimensions decrease or increase in sequence along the telescopic direction and are coaxially slidably arranged. Among them, the shapes (cross-sectional shapes) of the fixed part 211 and the movable part 212 can be the same, for example, both are square columns or cylinders or elliptical cylinders, or can be different, for example, a cylindrical fixed part 211 and a square-column-shaped movable part 212 can be slidably arranged with each other, as long as sliding can be realized on the side surfaces where the two slide relative to each other. Figures 2 - 3 A specific structure is shown. In this structure, the outer dimensions of the fixed part 211 and the movable part 212 decrease in sequence along the telescopic direction, and the shapes of the fixed part 211 and the movable part 212 are both cylindrical.

[0050] The telescopic pliers handle further includes a telescopic driving mechanism 213 and a sliding component 214. Adjacent two pliers handles are connected through the sliding component 214. Figure 3In the illustrated embodiment, a sliding assembly 214 is disposed oppositely between the side walls of the fixed portion 211 and the movable portion 212. The sliding assembly 214 may be in the form of a slide rail cooperating with a slide seat or other forms that can enable the mutual sliding of the fixed portion 211 and the movable portion 212. The sliding assembly 214 ensures the sliding stability between the fixed portion 211 and the movable portion 212 and the smoothness of the telescopic operation.

[0051] Exemplarily, for the convenience of driving control, the telescopic driving mechanism 213 is a micro electric telescopic rod, and a micro electric push rod such as but not limited to a voltage of 12 / 24V and a speed of 8mm / s can be selected. Or select the electric push rod of Changzhou Louis Electric Push Rod Co., Ltd. with the model SXTL.

[0052] The telescopic driving mechanism 213 is located within the fixed portion 211, and the output end 2130 of the telescopic driving mechanism 213 is fixedly connected to the movable portion 212. When the telescopic driving mechanism 213 is activated, it drives the movable portion 212 to extend or retract relative to the fixed portion 211.

[0053] To further improve the automation and convenience of telescopic control, the telescopic pliers handle in the present utility model further includes a controller (not shown in the figure). The input end of the telescopic driving mechanism 213 is signal-connected to the output end of the controller. The controller controls the start-stop and running direction of the telescopic driving mechanism 213, and further controls the telescopic direction and stroke of the telescopic pliers handle.

[0054] Furthermore, a rubber sleeve 4 is sleeved on the outer walls of the ends of the second pliers handle 22 and the first pliers handle 21, and anti-slip patterns are provided on the rubber sleeve 4. Through the rubber sleeve 4, not only the gripping force of the second pliers handle 22 and the first pliers handle 21 is improved, but also the comfort and stability of the second pliers handle 22 and the first pliers handle 21 are increased.

[0055] It should be noted that in the present utility model, the pliers handle 2 and the semi-circular ring member are made of any non-wear-resistant material such as aluminum alloy material or other light metal materials or non-metal materials. Of course, the pliers handle 2 and the semi-circular ring member in the present utility model are not limited to non-wear-resistant materials such as aluminum alloy, and can also be wear-resistant materials. That is, the pliers handle 2 and the semi-circular ring member in the present utility model can be applicable to any material that can achieve a supporting effect.

[0056] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
