[0050] A fixing mechanism 5 arranged on the plug-in housing 4 for fixing the axe head 1 and the plug-in housing 4;

[0051] A crowbar head 6 disposed on one side of the axe handle 2;

[0052] A connecting structure 7 disposed on the crowbar head 6 for connecting the crowbar head 6 and the axe handle 2;

[0053] A plurality of locking tubes 8 sleeved on the axe handle 2;

[0054] And a locking mechanism 9 disposed on the locking tube 8 for fixing the locking tube 8 and the axe handle 2;

[0055] Wherein four grooves 10 are sequentially formed in a circular array on each of the plurality of axe handles 2, and one end of the locking mechanism 9 is inserted into the groove 10.

[0056] A multifunctional fire axe that is easy to carry provided by the present utility model. When in use, the crowbar head 6 is installed on the axe handle 2 through the connecting structure 7, so that the function of the device is diversified. It can not only be used for chopping, but also be used like a crowbar. After that, when the axe handle 2 needs to be folded, the locking mechanism 9 on the locking tube 8 is manually pulled, and one end of it is removed from the groove 10. Then, the locking tube 8 is manually pushed or pulled away from the connection between the two axe handles 2, and the connecting mechanism 3 is exposed. Thus, under the action of the connecting mechanism 3, the axe handle 2 can be folded, so that the fire axe is convenient for storage and carrying. Finally, the fixing mechanism 5 in the round hole is manually pressed inward by the axe head 1, and then the axe handle 2 is manually pulled, so that the axe handle 2 can pull out the insertion shell 4 from the installation port of the axe head 1, thus facilitating the replacement of the worn axe head 1 or the broken axe handle 2.

[0057] Further, the connecting mechanism 3 includes a first U-shaped plate 31 and a second U-shaped plate 32 that are symmetrically arranged, and the first U-shaped plate 31 and the second U-shaped plate 32 are respectively fixedly installed on two adjacent axe handles 2.

[0058] Specifically, through the cooperation of the first U-shaped plate 31, the second U-shaped plate 32 and the strip-shaped plate 33, two adjacent axe handles 2 can be folded, so that the fire axe is convenient for storage and carrying.

[0059] Further, the connecting structure 7 includes a threaded column 71 fixedly installed at one end of the crowbar head 6. A first thread groove 72 is formed at one end of the last axe handle 2, and the threaded column 71 is threadedly connected to the inside of the first thread groove 72.

[0060] Specifically, by manually screwing the threaded column 71 into the first thread groove 72, the crowbar head 6 can be stably installed on the axe handle 2, so that the function of the device is diversified.

[0061] Furthermore, the locking mechanism 9 includes a fixing ring 91 fixedly installed on the outer side of the locking tube 8. Two U-shaped frames 92 are symmetrically installed on the outer side wall of the fixing ring 91. A T-shaped plug rod 93 is movably inserted into the U-shaped frame 92. A first spring 94 is arranged on the T-shaped plug rod 93, and one end of the T-shaped plug rod 93 passes through the locking tube 8 and is inserted into the groove 10.

[0062] Specifically, manually move the locking tube 8 to the middle of the two axe handles 2, so that the multiple axe handles 2 can stand upright. Then, the tension of the first spring 94 pushes the T-shaped plug rod 93 inserted into the U-shaped frame 92, and one end of the T-shaped plug rod 93 is inserted into the inside of the groove 10, so as to fix and limit the locking tube 8. Furthermore, the operator can lift the axe head 1 through the axe handle 2 for chopping. On the contrary, manually pull the T-shaped plug rod 93 and move its one end out of the groove 10. Then, manually move the locking tube 8 and move it away from the connecting mechanism 3. Thus, under the action of the connecting mechanism 3, the axe handle 2 can be folded, and the fire axe is convenient for storage and carrying.

[0063] Furthermore, two first bolts 13 are symmetrically threadedly connected to the fixing ring 91, and one end of each of the two first bolts 13 passes through the locking tube 8 and is inserted between the locking tube 8 and the groove 10.

[0064] Specifically, when the T-shaped plug rod 93 is inserted into the groove 10, manually rotate the first bolt 13 threadedly connected to the fixing ring 91 and insert its one end into the groove 10, so as to improve the fixing effect of the T-shaped plug rod 93.

[0065] Furthermore, a rubber sleeve 12 is fixedly installed on the outer side wall of the locking tube 8, and the rubber sleeve 12 is located on one side of the locking mechanism 9.

[0066] Specifically, the rubber sleeve 12 is beneficial to improving the comfort when the operator holds the device by hand for chopping.

[0067] Furthermore, the fixing mechanism 5 includes a T-shaped plug rod 51 penetrating through the insertion shell 4, and one end of the T-shaped plug rod 51 is inserted into the round hole on the axe head 1. The other end of the T-shaped plug rod 51 penetrates through one side of the support plate in the insertion shell 4 and is fixedly installed with a limit disc 53. A second spring 52 is sleeved on the outer side wall of the T-shaped plug rod 51, and the second spring 52 is located on one side of the support plate.

[0068] Specifically, manually insert the socket shell 4 into the installation opening on the axe head 1. After that, when the round hole on the T-shaped insertion rod 51 is aligned and connected with the round hole on the axe head 1, push the T-shaped insertion rod 51 through the second spring 52, and insert one end of the T-shaped insertion rod 51 into the round hole. At the same time of insertion, the T-shaped insertion rod 51 can be limited by the limiting disc 53 and the support plate in the socket shell 4, so that the axe handle 2 and the axe head 1 are convenient to disassemble and assemble, and further avoid replacing the worn axe head 1 or the broken axe handle 2.

[0069] Further, a second threaded groove is formed on one side of the T-shaped insertion rod 51, and a second bolt 11 is threadedly connected in the second threaded groove.

[0070] Specifically, manually screw the second bolt 11 into the second threaded groove, so as to improve the insertion and fixation effect and stability performance of the fixing mechanism 5.
