[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are used only for explaining the utility model, and cannot be understood as limiting the utility model.
[0031] The embodiments will be described below according to the overall structure of the utility model.
[0032] An escape pliers for fire rescue, as shown in Figure 1 - Figure 4 The escape pliers body 1 is provided with the first pliers handle 3 at the bottom, the first pliers handle 3 is provided with the second pliers handle 4 at the bottom, the outer wall of the first pliers handle 3 is provided with the groove 6, the end of the second pliers handle 4 is provided with the limiting groove 7, and the end of the second pliers handle 4 is provided with the protruding block 10. When a narrow space is needed, the escape pliers is used. At this time, the second pliers handle 4 can be pushed, the protruding block 10 at the end of the second pliers handle 4 is retracted into the limiting groove 7 under the extrusion of the first pliers handle 3, and then the protruding block 10 is pushed out under the action of the spring 9 when contacting the groove 6 above the first pliers handle 3, so that the second pliers handle 4 is clamped in the first pliers handle 3, and the length of the escape pliers body 1 is reduced, so that the escape pliers can be conveniently used in the narrow space.
[0033] Please refer to Figure 2 and Figure 3 The limiting groove 7 is provided with the fixed block 8 inside, one end of the fixed block 8 is connected with the spring 9, and one end of the spring 9 is fixed with the protruding block 10. When the second pliers handle 4 needs to be retracted, the second pliers handle 4 is moved. At this time, the protruding block 10 at the end of the second pliers handle 4 is retracted into the limiting groove 7 under the action of the spring 9, and then the protruding block 10 is retracted into the limiting groove 7 under the action of the spring 9 when contacting the groove 6 above the first pliers handle 3, so that the second pliers handle 4 is clamped in the first pliers handle 3, and the length of the escape pliers body 1 is reduced, so that the escape pliers can be conveniently used in the narrow space.
[0034] Please refer to Figure 3 The protruding block 10 is horizontally distributed on both sides of the second pliers handle 4, and the protruding block 10 is arc-shaped. The protruding block 10 is distributed on both sides of the second pliers handle 4, so that the second pliers handle 4 is fixed more firmly and will not be easily loosened. The protruding block 10 is arc-shaped, so that the friction force of the protruding block 10 when contacting the inner wall of the first pliers handle 3 is smaller, and the movement is more relaxed.
[0035] Please refer to Figure 1 and Figure 4The number of the grooves 6 is three groups, and the inner wall of the groove 6 is arc-shaped, when the second handle 4 needs to be stretched and contracted, the three groups of grooves 6 can make the second handle 4 stretch and contract more conveniently, and the arc-shaped inner wall makes the resistance that the protrusion 10 receives smaller when moving.
[0036] Please refer to Figure 1 The diameter of the second handle 4 is smaller than that of the first handle 3, and the length of the second handle 4 is smaller than that of the first handle 3, so that the second handle 4 can be completely retracted into the first handle 3 when retracted, so that the overall length of the escape pliers body 1 is reduced, and it is more convenient to use in a small space.
[0037] Please refer to Figure 1 and Figure 2 The bottom of the second handle 4 is provided with a tapered block 5, which is convenient for breaking glass and other objects. When the window glass is sealed and cannot be opened due to other reasons during the escape process, the second handle 4 can be adjusted, the second handle 4 is pulled down, the second handle 4 is taken out, the tapered block 5 at the bottom end of the second handle 4 is used to knock the window glass, and the practicability of the fire escape pliers is improved.
[0038] Please refer to Figure 1 The end of the escape pliers body 1 is provided with a plier head 2 for destroying obstacles. When the escape pliers are needed, the plier head 2 is pressed to make the inner side of the plier head 2 cut the fireproof hard material.
[0039] Please refer to Figure 3 The width of the limiting groove 7 is greater than that of the protrusion 10, which is convenient for accommodating the protrusion 10. When the second handle 4 is stretched and contracted, the protrusion 10 is extruded, and under the action of the spring 9, the protrusion 10 is retracted into the limiting groove 7, so that the second handle 4 is not affected when moving.
[0040] The utility model discloses a working principle is: this fire escape pliers by escape pliers body 1 and first handle 3 and second handle 4 and end pliers head 2 are composed, when needing to use escape pliers, through pressing two groups of handle, make that pliers head 2 inside mouth knife can cut to fire hard material, when in narrow space, need to use escape pliers, can push second handle 4 at this moment, through the protruding block 10 and spring 9 that second handle 4 end part sets, when pushing second handle 4, protruding block 10 will be under the extrusion of first handle 3, make protruding block 10 shrink in limiting groove 7, subsequently when contacting the recess 6 on first handle 3 top, protruding block 10 will be under the action of spring 9 and pop out outward, thereby make second handle 4 engage in first handle 3, make escape pliers body 1 length reduce, can also conveniently use in narrow space, when escaping, when window glass is sealed and cannot be opened because of other reasons, can through adjusting second handle 4, pull down second handle 4, take out second handle 4, through the taper block 5 that second handle 4 bottom end sets, knock window glass, after use, reset second handle 4 and store up, convenient escape pliers can also use easily in narrow space, improve fire escape pliers practicality.
[0041] Although the embodiments of the utility model have been shown and described, the specific embodiments are only the explanation of the utility model, and it is not the limitation of the utility model, and the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in the suitable way, and the person skilled in the art can make the modification, replacement and change of the embodiment without the creative contribution after reading the specification without departing from the principles and purposes of the utility model, but as long as in the patent right claim range of the utility model, it is protected by the patent law.
