At this time, the entire fire window-breaking hammer is in a straight line state. Different from the fire window-breaking hammer in the shape of the letter "L", the fire window-breaking hammer in the straight line state can be placed in the trouser pocket without occupying the internal space of the trouser pocket. At the same time, it is also convenient for users to carry, thereby improving the practicality of the device;
[0015] 2. During use, the staff can rotate the telescopic rod according to the actual use situation, move the threaded sleeve at the top of the telescopic rod to the limit plate, rotate the telescopic rod, and make the threaded sleeve threadedly connected with the second threaded groove, so as to adjust the length of the fire window breaker hammer. By extending the handle of the fire window breaker hammer, it can be more labor-saving during use, which improves the efficiency of use. By shrinking the handle of the fire window breaker hammer, the size of the overall window breaker hammer is reduced, and the storage capacity of the window breaker hammer is improved, so it is more convenient to carry. During work, the staff can also use the lanyard at the bottom of the telescopic rod and put it on the wrist to ensure that the window breaker hammer will not fall off during use, which improves the safety during use. At the same time, the lanyard can also be used to hang on the belt or backpack strap, which improves the overall portability of the fire hammer. After using the device, the staff can rotate and pull out the screw threadedly connected to the second threaded hole, and then rotate the window breaking hammer head upward 90 degrees. At this time, the fire window breaking hammer is in an L-shaped state, so that the window breaking hammer head and the fire window breaking hammer handle are located on the same straight line, and the protective sleeve is clamped on the fire window breaking hammer handle. At this time, the entire fire window breaking hammer is in an L-shaped state. Different from the fire window breaking hammer in the shape of the letter "L", the fire window breaking hammer in the L-shaped state can be placed in the trouser pocket without occupying the internal space of the trouser pocket. It is also convenient for the user to carry, thereby improving the practicability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.
[0023] like Figure 1-Figure 5 As shown, a portable fire window breaking hammer comprises a mounting groove 2, which is arranged at the top of a fire window breaking hammer handle 1, a window breaking hammer head 3 is rotatably arranged inside the mounting groove 2, a rotating hole 4 is arranged on the left side of the window breaking hammer head 3, a first mounting hole 5 is arranged on the outer wall surface of the fire window breaking hammer handle 1, a first threaded hole 6 is arranged on one side inside the mounting groove 2, the first mounting hole 5 is connected with the mounting groove 2, the first mounting hole 5 and the rotating hole 4 correspond to the first threaded hole 6, a bolt 7 is inserted inside the first mounting hole 5, the threaded end of the bolt 7 passes through the rotating hole 4 and is connected with the internal thread of the first threaded hole 6, and the front side of the window breaking hammer head 3 is fixed There is a card interface 8, a fixing hole 9 is opened through the card interface 8, a baffle 10 is fixed inside the mounting groove 2, a second threaded hole 11 is opened on one side of the inner wall of the mounting groove 2, and a second mounting hole 12 is opened on the other side of the inner wall of the mounting groove 2. The second mounting hole 12 and the fixing hole 9 correspond to the second threaded hole 11. A screw 13 is inserted into the second mounting hole 12, and the threaded end of the screw 13 passes through the fixing hole 9 and is connected to the internal thread of the second threaded hole 11. A protective cover 20 is detachably clamped on the window breaking hammer head 3, and the bottom end of the protective cover 20 extends to the peripheral wall of the fire window breaking hammer handle 1 and fits with the peripheral wall of the fire window breaking hammer handle 1.
[0024] During use, the staff first pulls out the protective cover 20, and then rotates and pulls out the screw 13 threadedly connected to the second threaded hole 11. At this time, the staff can bend the window breaking hammer 3 downward, and the window breaking hammer 3 will rotate ninety degrees on the axis of the bolt 7, so that the card interface 8 on the front side of the window breaking hammer 3 is against the baffle 10, and then the threaded end of the screw 13 passes through the fixing hole 9 and is connected to the internal thread of the second threaded hole 11, so that the window breaking hammer 3 is horizontally fixed on the fire window breaking hammer handle 1, thereby forming a fire hammer in the shape of the letter "L".
