[0029] like Figures 1 to 5 As shown, this utility model embodiment provides a portable emergency fire axe, including an axe head 1, a first handle 2 and a second handle 3, and includes a first use state, a second use state and a third use state.
[0030] like Figure 1 and Figure 2 As shown, this is the first usage state. In this state, the first handle 2 and the second handle 3 are coaxially connected and their axes are parallel to the direction of the axe blade's extension, forming the usage form of a standard fire axe for chopping. In this usage state, the connection of the two handles extends the overall length of the handles, thus facilitating chopping actions and providing greater chopping force.
[0031] Specifically, the axe 1 has a first connecting lug 11 and a second connecting lug 12 on opposite sides of the axe blade extension direction, and the two connecting lugs protrude in the axe blade extension direction, such as Figure 3 As shown.
[0032] One end of the first handle 2 is hinged to the first connecting lug 11, and the pivot is perpendicular to the surface of the axe head 1, allowing it to swing away from and towards the axe blade.
[0033] A sleeve 4 is fitted onto the first handle 2, and the sleeve 4 is threadedly connected to the first connecting lug 11, thereby fixing the first handle 2 and the axe 1 in the first use state, that is, the axis of the first handle 2 is parallel to the extension direction of the axe blade, so that the first handle 2 cannot rotate.
[0034] One end of the second handle 3 is threadedly connected to the end of the first handle 2 away from the axe 1, forming a coaxial series connection. The other end of the second handle 3 is provided with a relief groove 31 that can be inserted into the second connecting ear 12. The relief groove 31 is provided with an elastic buckle 32. The second connecting ear 12 is provided with a slot 121 that engages with the elastic buckle 32.
[0035] More specifically, the first connecting ear 11 is plate-shaped, and the first handle 2 is rod-shaped, with a notch-shaped groove at one hinged end for the first connecting ear 11 to be inserted, and the first handle 2 can rotate 180 degrees to both sides.
[0036] The inner diameter of the sleeve 4 is the same as the diameter of the first handle 2, and it can slide on the first handle 2. The first connecting lug 11 is inserted into the sleeve 4 and threadedly connected to the inner wall of the sleeve 4.
[0037] The length of the sleeve 4 is greater than the protruding length of the first connecting ear 11, so that in the first use state, part of the sleeve 4 is fitted onto the first connecting ear 11 and the other part is fitted onto the first handle 2, so that the connection between the first handle 2 and the axe 1 is fixed.
[0038] The second handle 3 is also rod-shaped and has the same length as the first handle 2, so that in the second and third use states, the two handles are of equal length, facilitating the application of force and carrying. See details. Figure 4 and Figure 5 , and the following description.
[0039] The second handle 3 has an external thread at one end, and the end face of the first handle 2 away from the axe 1 has a threaded hole that mates with it, allowing the second handle 3 to be detachably connected to the first handle 2. When space is limited, the second handle 3 can be left unconnected, and only the first handle 2 can be used for chopping.
[0040] The relief groove 31 and elastic buckle 32 provided at the other end of the second handle 3 are used to connect and cooperate with the second connecting ear 12 to form a second use state or a third use state.
[0041] Specifically, the recessed groove 31 is also notched, connecting the side wall and end face of the second handle 3. The second connecting ear 12 is plate-shaped and can be inserted into the recessed groove 31. An elastic buckle 32 is disposed on the side wall of the recessed groove 31, including a receiving groove on the side wall of the recessed groove 31, a spring located in the receiving groove, and a locking block located outside the spring. The exposed portion of the locking block is hemispherical. When the second handle 3 is inserted into the second connecting ear 12, the locking block engages with the locking groove 121 on the second connecting ear 12, positioning and connecting the second handle 3 and the second connecting ear 12. The locking groove 121 is disposed on the plate surface of the second connecting ear 12.
[0042] To facilitate quick and accurate connection between the elastic buckle 32 and the slot 121, the second connecting ear 12 is provided with a guide groove 122, and a slide bar 33 is provided in the clearance groove 31, which can slide and engage with the guide groove 122. The guide groove 122 is formed on the plate surface of the second connecting ear 12, and its extension direction is consistent with the protrusion direction of the second connecting ear 12. The slide bar 33 extends radially along the second handle 3, so as to form a second and third use state of the emergency fire axe by plugging in. In this embodiment, the slot 121 is located in the guide groove 122, and the elastic buckle 32 is located on the slide bar 33.
[0043] To improve the connection stability between the second handle 3 and the second connecting ear 12, two elastic buckles 32 are provided, symmetrically arranged on the two symmetrical sidewalls of the relief groove 31. Two slots 121 are provided, respectively located on the two side plates of the second connecting ear 12, for the two elastic buckles 32 to engage. In this embodiment, the two slots 121 are designed to be identical and are in the shape of through holes.
[0044] From the first usage state, unscrew the second handle 3 and slide it toward the axe head 1 with the slide bar 33 aligned with the guide groove 122, in the same plane as the axe blade, and with the threaded end away from the axe blade, so that the second connecting lug 12 is inserted into the relief groove 31. Then, screw the sleeve 4 to disengage it from the first connecting lug 11. At this time, rotate the first handle 2 upward, that is, rotate the non-hinged end of the first handle 2 away from the axe blade until it is parallel to the second handle 3. This forms the second usage state, used when the axe blade needs to be used for prying, such as... Figure 4 As shown.
[0045] In the second usage state, since the axes of the two handles are perpendicular to the extension direction of the axe blade, the distance between the force application point and the axe blade can be extended when a prying action is required, providing a greater prying torque. Furthermore, the two handles are of equal length, facilitating simultaneous application of force.
[0046] When carrying or storing, the assembly method in the second usage state can be referenced. The difference is that both the first handle 2 and the second handle 3 extend from the connecting lug towards the axe blade. That is, both handles are folded 180 degrees relative to their position in the second usage state to form the third usage state. Figure 5 As shown.
[0047] In the third usage state, the axe blade is located between the two handles and is protected, thus preventing the axe blade from being easily touched. In addition, the two handles are parallel to each other and are folded with the axe head 1, which reduces the overall length of the emergency fire axe, making it easier to carry and store.
[0048] Other examples Figure 2 and Figure 5As shown, both the first handle 2 and the second handle 3 are provided with a strip groove 5. In the third use state, the strip groove 5 is located on the opposite side of the first handle 2 and the second handle 3, allowing the two ends of the axe blade to be inserted. This not only better protects the axe blade, but also further reduces the size of the emergency fire axe after folding, improving portability.
[0049] In addition, the second grip 3 has a fixing strap 6 near the threaded part. The middle of the fixing strap 6 is connected to the second grip 3, and the two ends are provided with Velcro. When the two ends of the fixing strap 6 are connected, they form a loop that can be put on the shaft of the first grip 2 to fix the two grips together, making them less likely to come apart and convenient to carry and use.
[0050] This utility model provides a portable emergency fire axe that can be configured into at least three usage states through the connection of two handles and two connecting ears. In the first usage state, the overall length of the handles can be extended to facilitate chopping actions and provide greater chopping force. In the second usage state, the two handles extend away from the axe blade, with their axes perpendicular to the direction of the axe blade's extension. This extends the distance between the force application point and the axe blade when a prying action is required, facilitating the provision of greater prying torque. In the third usage state, the two handles extend towards the axe blade, protecting it in the middle and preventing it from being easily touched. In addition, the two handles are parallel to each other and folded with the axe head, reducing the length of the fire axe and making it easy to carry.
