DETAILED DESCRIPTION
[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.
[0037] like Figures 1 to 8 As shown, a fire-fighting wire cutter 100 of the utility model comprises a first clamp body 1, a second clamp body 2, a first handle bar 3 and a second handle bar 4.
[0038] like Figure 1 and Figure 3 As shown, a hinge shaft 5 is provided in the middle of the first pliers body 1 and the second pliers body 2, and they are hinged to each other to form a pliers head A, and the area of the pliers head A in the length and width direction is for the user to stand on; for example, the length and width of the pliers head A can be set to be slightly larger than the length and width of an adult's feet together, so that the user can stand on it, and the specific length and width parameters can be adjusted and set according to actual conditions.
[0039] like Figure 2 As shown, a movable opening and closing jaw A1 is formed between the front ends of the first clamp body 1 and the second clamp body 2, which is used to cut window obstacles, etc.; the rear end of the first clamp body 1 has a female connecting groove C1, the rear end of the second clamp body 2 has a male connecting head C2, and the middle part of the hinge shaft 5 has a female connecting groove C1; the front end of the first handle rod 3 has a male connecting head C2, and the rear end of the first handle rod 3 has a hook 6; the front end of the second handle rod 4 has a female connecting groove C1, and the rear end of the second handle rod 4 has a male connecting head C2; the male connecting head C2 and the female connecting groove C1 are detachably connected to each other.
[0040] By using the above structure, a wire cutter 10 for breaking windows or an emergency pedal 20 can be assembled, and the fire wire cutter 100 can be used as a household fire escape product and can be popularized in residents' homes for emergency escape when a fire occurs. The specific usage method is as follows:
[0041] See also Figure 4 When the front end of the first handle rod 3 is connected to the rear end of the first pliers body 1, and the front end of the second handle rod 4 is connected to the rear end of the second pliers body 2, the first handle rod 3, the second handle rod 4 and the pliers head A form a wire cutter 10; the first handle rod 3 and the second handle rod 4 form a handle B, which can control the opening and closing of the jaws A1 of the pliers head A to cut and break the anti-theft window outside the window, making it easier for the user to escape from the room.
[0042] See also Figure 5 and Figure 6 , when the male connector C2 at the front end of the first handle bar 3 is connected to the female connector C1 at the front end of the second handle bar 4, and the male connector C2 at the rear end of the second handle bar 4 is connected to the female connector C1 in the middle of the hinge shaft 5, the first handle bar 3, the second handle bar 4 and the clamp head A form an emergency pedal 20. That is, after the user breaks the window, the wire cutter 10 can be disassembled and reassembled into the emergency pedal 20. Before the user escapes from the room, the hook 6 of the first handle bar 3 is first hooked and fixed on the window edge, so that the clamp head A is located outside the window. Therefore, when the user gets out of the window, he can stand or squat on the clamp head A for leverage, so as to save physical strength while avoiding the fire in the room. He only needs to hold the wall or window for balance and stability, and does not need to climb the window too hard, which can improve the success rate of escape.
[0043] Specifically, the male connector C2 in this embodiment can be a threaded protrusion, and the female connector groove C1 can be a threaded groove. The threads in the figure are schematically drawn. The threaded connection can ensure the stability of the connection between them. Of course, other connection structures can also be used to achieve corresponding male and female docking.
[0044] Another example Figure 1 , Figure 2 and Figure 5 As shown, the hook 6 of the first handle bar 3 is a foldable structure to facilitate product storage.
[0045] The hook 6 comprises a first hook body 61 and a second hook body 62; the rear end side wall of the first handle bar 3 is provided with a first hook groove 31, the inner end of the first hook body 61 is hinged to the rear end of the first hook groove 31, and the first hook body 61 rotates inwards and is retracted in the first hook groove 31, and the maximum angle between the first handle bar 3 and the hook body 61 and the hook body 61 is 90 degrees; the inner side surface of the first hook body 61 close to the first hook groove 31 is provided with a second hook groove 611, the inner end of the second hook body 62 is hinged to the outer end of the second hook groove 611, and the second hook body 62 rotates inwards and is retracted in the second hook groove 611, and the maximum angle between the first hook body 61 and the hook body 61 is 90 degrees. Therefore, when the first hook body 61 and the second hook body 62 of the hook 6 are unfolded, a groove D can be formed between the hook 6 and the first handle bar 3, so that the hook 6 can be firmly buckled at the window edge E and remain stable.
[0046] For further information, see Figure 7 In order to improve the stability of the hook 6 buckle, in this embodiment, a locking through hole 621 is provided at the outer end of the second hook body 62, and a locking through hole 311 is provided at the front end of the first hook groove 31; thereby, the second hook body 62 can bypass the cross bar F of the anti-theft window on the window, and the outer end of the second hook body 62 is inserted into the first hook groove 31, so that the locking through hole 621 of the second hook body 62 can be aligned with the locking through hole 311, and then by inserting the latch 7, a hollow closed triangular structure can be formed between the first hook body 61 and the second hook body 62 and the first handle bar 3, that is, the hook 6 can be locked on the cross bar F of the anti-theft window to prevent the hook 6 from slipping off the window edge E, thereby further improving the safety of use.
[0047] Another example Figure 8 and Fig. 9 The rear end of the second handle rod 4 is also detachably connected with a demolition piece 8; the demolition piece 8 includes a demolition rod body 81, a demolition blade 82 and a demolition support rod 83; one end of the demolition rod body 81 has a female connecting groove C1, and the demolition rod body 81 is vertically detachably connected to the second handle rod 4, the demolition blade 82 is laterally fixed on the demolition rod body 81, the demolition support rod 83 is longitudinally fixed on the demolition rod body 81, and the demolition blade 82 has a cutting edge 821 on the side facing the demolition rod body 81.
[0048] The cutting blade 821 of the present embodiment is only located on one side of the demolition rod body 81 , or the cutting blade 821 may be provided on both sides.
[0049] Thus, the second handle bar 4 can be detached from the pliers head A and assembled with the breaking piece 8, which can be used to cut some safety nets or anti-theft nets with small gaps that cannot be cut with the wire cutters 10. Fig. 9As shown, when in use, the cutting edge 821 of the demolition blade 82 is pressed against the inner side of the horizontal line G1 of the safety net to be cut, and then the demolition support rod 83 is kept on the outer side of the vertical line G2 of the safety net, and the second handle rod 4 is pressed down with force, driving the demolition rod body 81 and the demolition blade 82 to rotate with the demolition support rod 83 as a fulcrum, thereby cutting the horizontal line G1 of the safety net, thereby saving effort and conveniently cutting the safety net or anti-theft net.
[0050] In this embodiment, the demolition blade 82 is triangular, and one of the tips of the demolition blade 82 faces the female connection groove C1 of the demolition rod body 81. Therefore, the demolition blade 82 can be provided with two vertically spaced fixed shafts 84 to be fixedly connected to the demolition rod body 81. The two fixed shafts 84 can stably connect and fix the demolition blade 82 to the demolition rod body 81, and can improve the structural strength and shear force of the demolition blade 82.
[0051] In this embodiment, the demolition support rod 83 can be detachably connected to the connection groove 811 on the demolition rod body 81 through the connecting stud 831. Of course, the two can also be an integrated structure.
[0052] In this embodiment, the first handle bar 3 and the second handle bar 4 are made of glass fiber reinforced plastics, which can be light and high in strength.
[0053] See also Figure 3 The pliers head A is provided with a hinge hole A2 for the hinge shaft 5 to pass through; and the front of the first pliers body 1 and the back of the second pliers body 2 form a radially outwardly expanding annular groove A21 on the outer periphery of the hinge hole A2; the hinge shaft 5 is passed through the hinge hole A2, and both ends of the hinge shaft 5 are rotatably embedded in the annular groove A21, and both ends of the hinge shaft 5 do not protrude from the front and back of the pliers head A. Therefore, by setting the hinge shaft 5 not to protrude, the front and back of the pliers head A can be kept flat, which is convenient for standing on.
