Mounting plates are provided on both sides of the buckle 23, and the buckle 23 is rotatably plugged into the buckle mounting portion 22 through the mounting plates. A first torsion spring 24 is provided between the two mounting plates, and the first torsion spring 24 is sleeved on the buckle mounting portion 22. The two pins of the first torsion spring 24 respectively cooperate with the connecting rod 21 and the buckle 23; guide grooves 42 are also provided on both sides of the arrow magazine 4, and the guide grooves 42 are located below the bowstring groove 41, and the guide grooves 42 cooperate with the buckle mounting portion 22, and a guide groove matching portion 221 matching with the guide grooves 42 is provided on the buckle mounting portion 22.

[0024] The connecting rod 21 pulls the buckle 23 to move in the direction of the guide groove 42. A hanging portion 231 is provided above the buckle 23. In the direction of the guide groove 42, the tip of the hanging portion 231 extends to below the maximum diameter of the bowstring 32 in this direction, so as to prevent the bowstring 32 from falling off during the process of pulling the bowstring 32. A top block matching portion 232 is provided below the buckle 23, and a top block 43 is provided at the end of the arrow chamber 4. The top block 43 matches with the top block matching portion 232.

[0025] An arrow 5 is placed in the arrow chamber 4. In the present embodiment, two arrows 5 are provided, one above and one below. During the placement of the arrow 5, the arrow 5 is pressed on the bowstring. When the bowstring 32 is pulled to the tail end of the arrow 5 under the action of the bow drawing mechanism 2, the bowstring 32 bounces upward and contacts the tail end of the arrow 5, thereby launching the arrow 5.

[0026] A fixing mechanism 45 is provided on one side above the arrow magazine 4 , and the fixing mechanism 45 is used to fix the two arrows 5 . A limiting mechanism 44 is provided between the two arrows 5 to avoid mutual influence between the two arrows 5 .

[0027] The fixing mechanism 45 includes a pressure plate mounting portion 451 and a torsion spring matching portion 452. A pressure plate 453 is rotatably mounted through the pressure plate mounting portion 451, and a second torsion spring 454 is rotatably mounted through the pressure plate mounting portion 451. Two pins of the second torsion spring 454 are respectively matched with the torsion spring matching portion 452 and the pressure plate 453. Under the action of the second torsion spring 454, the pressure plate 453 is tightly pressed on the upper arrow 5.

[0028] The limiting mechanism 44 includes a mounting groove 441, and the mounting groove 441 is arranged on both sides of the arrow magazine 4. A connecting spring is fixedly installed in the mounting groove 441, one end of the connecting spring is fixedly connected to the inner side of the mounting groove 441, and the other end of the connecting spring is fixedly connected to a limiting block 442. The two limiting blocks 442 are located between the two arrows 5 under the action of the connecting spring force, and an arc-shaped matching portion is provided at the position where the two limiting blocks 442 contact the arrows 5. When the arrow below is shot out, under the action of the upper pressure plate 453, the limiting block 442 shrinks into the mounting groove 441, and the arrow 5 above is pressed into the bottom of the limiting block 442, and the limiting block 442 pops out to fix the arrow 5.

[0029] A mounting frame 7 is provided above the arrow magazine 4 , and a UAV quick release 6 is mounted through the mounting frame 7 . The window breaker of the present invention is docked with the UAV through the quick release 6 , and a driving motor 11 is connected to the quick release 6 .

[0030] In this embodiment, the arrow 5 includes an arrow shaft 51, the front end of the arrow shaft 51 is hollow and an arrow hammer 55 is installed therein, wherein a limiting rod 551 is provided at the end of the arrow hammer 55, a second spring 58 is sleeved on the arrow hammer 55, and the second spring 58 is clamped and fixed by the limiting rod 551, and a limiting groove 511 is correspondingly provided on the arrow shaft 51, the limiting rod 551 cooperates with the limiting groove 511 and extends to the outside of the arrow shaft 51 through the limiting rod matching groove 541.

[0031] A limiting portion 52 is provided on the arrow shaft 51, a pressing ring 54 is provided behind the limiting rod 551, a first spring 53 is provided between the pressing ring 54 and the limiting portion 52, the first spring 53 is sleeved on the arrow shaft 51, a limiting rod matching groove 541 is provided on the pressing ring 54, and the limiting rod matching groove 541 matches with the limiting rod 551.

[0032] A window breaking hammer 56 is also provided at the front part of the arrow shaft 51. The front end of the window breaking hammer 56 is hinged to the arrow shaft 51, and the rear end of the window breaking hammer 56 is pressed and fixed by a pressing ring 54. A compression spring 57 is provided between the window breaking hammer 56 and the arrow shaft 51. The upper end of the compression spring 57 is fixedly connected to the window breaking hammer 56, and the lower end of the compression spring 57 abuts against the arrow shaft 51.

[0033] The principle of the present invention is: During use of the present invention, two arrows 5 are loaded into the arrow magazine 4. During the process, there is no need to disassemble the drone quick release 6, etc. The arrows 5 are inserted backwards from the front end of the arrow magazine 4. During the process, the lower arrow 5 is installed first, and then the upper arrow 5 is installed. When installing the upper arrow 5, the pressure plate 453 at the rear of the arrow magazine 4 is pulled up. After the installation is completed, the pressure plate 453 is lowered, which can realize the compression and fixation of the two arrows 5. During the process, the pressure plate 453 and the quick release 6 do not interfere with each other in space. At the same time, it should be noted during the installation process that the angle of the lower arrow 5 during the installation process is adjusted so that the bowstring 32 is pressed below the lower arrow 5.

[0034] After the installation is completed, the drone can be docked with the drone through the drone quick release 6, and the drone can be controlled to take off to the designated location to perform the window breaking operation. During the process, the drone controls the action of the electric push rod 1 (the electric push rod 1 is existing and will not be described in detail). The push rod 12 of the electric push rod 1 drives the connecting rod 21 during the extension process, and the connecting rod 21 pulls the bowstring 32 through the buckle 23. When the bowstring 32 is pulled to the tail end of the arrow shaft 51, the bowstring 32 bounces upward and rests on the tail end of the arrow shaft 51. The bowstring 32 continues to be pulled. Under the action of the top block 43, the buckle 23 rotates and releases the bowstring 32, thereby launching the arrow 5 below.

[0035] When the arrow 5 below is launched, since the upper arrow 5 is suspended in the air (there is no support below the limit block 442), under the action of the pressure plate 453, the limit block 442 contracts inward and presses the upper arrow 5 downward. When the arrow 5 is pressed downward, the limit block 442 pops up to fix the arrow 5. At this time, the electric push rod 1 retracts. When the electric push rod 1 contacts the bowstring 32, due to the smooth design of the front end of the buckle 23, the bowstring 32 is forced to bend and deform downward and cooperate with the buckle 23. The above process is repeated to achieve the launch of the second arrow 5.

[0036] When the arrow 5 is fired, the arrow hammer 55 at the front end of the arrow 5 first contacts the glass, and a cracking network centered on the impact point appears at the contact point between the arrow hammer 55 and the glass. Under the action of the impact force, the arrow hammer 55 contracts backwards. At this time, the limit rod 551 drives the pressure ring 54 to contract backwards. When the pressure ring 54 contracts backwards, under the action of the compression spring 57, the window-breaking hammer 56 pops outward, thereby further smashing the above-mentioned cracking network and realizing the process of breaking the glass.

[0037] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that are the same or similar to those of the present application fall within the protection scope of the present invention.
