The internal threaded ring 201 is fixedly mounted on one side of the first housing 1, one side of the internal threaded ring 201 is threadedly sleeved with the external threaded tube 202, one side of the external threaded tube 202 is fixedly connected to the limiting ring 203, and the interior of the external threaded tube 202 is fixedly connected to the first A snap ring 204, a first spring 205 is fixedly connected to one side of the first snap ring 204, a button 207 is fixedly connected to one side of the first spring 205, a second snap ring 206 is movably connected to one side of the button 207, a first sleeve 208 is fixedly connected to one side of the button 207, a first clamping block 209 is fixedly connected to one side of the first sleeve 208, a first servo motor 210 is fixedly connected to one side of the first clamping block 209, an output end of the first servo motor 210 is fixedly connected to a second clamping block 211, and a second sleeve 212 is fixedly connected to one side of the second clamping block 211;

[0040] The starting mechanism 2 also includes a tear gas tank body 213, a one-way valve 214, a positioning tube 215, a side hole 216 and a transfer tube 217. The tear gas tank body 213 is fixedly installed on one side of the second ring 212, and a one-way valve 214 is provided on the other side of the tear gas tank body 213. One side of the one-way valve 214 is movably connected to the positioning tube 215, and one side of the positioning tube 215 is provided with a side hole 216. The positioning tube 215 is fixedly connected to the inside of the transfer tube 217, and the transfer tube 217 is fixedly connected to one side of the turntable 302.

[0041] The tear gas tank body 213 is fixedly connected to one side of the rotating disk 302 , and the tear gas tank body 213 is movably installed inside the first housing 1 , and the one-way valve 214 is movably connected inside the transfer tube 217 .

[0042] The second clamping ring 206 is fixedly connected to the inside of the external threaded tube 202 , the external threaded tube 202 is fixedly connected to one side of the first shell 1 , and the second clamping block 211 is fixedly connected to one side of the tear gas tank body 213 .

[0043] It needs to be further explained that: when the tear gas tank body 213 needs to be replaced, first the external threaded tube 202 is rotated counterclockwise to disengage the internal threaded ring 201, and the tear gas tank body 213 can be placed into the interior of the first shell 1 through the internal threaded ring 201, and the one-way valve 214 on one side of the tear gas tank body 213 is aligned with the positioning tube 215, and then the external threaded tube 202 is aligned with the internal threaded ring 201 and rotated clockwise to complete the fixation of the internal threaded ring 201 and the external threaded tube 202; when the tear gas inside the tear gas tank body 213 needs to be released, the first clamping block 209 can be driven to push the first servo by pressing the button 207. The motor 210, the second clamping block 211 and the second sleeve ring 212 press against the tear gas tank body 213, so that the positioning tube 215 completely enters the one-way valve 214. At this time, the one-way valve 214 is opened by the positioning tube 215, and the compressed gas inside the tear gas tank body 213 carries the tear gas into the interior of the main regulating mechanism 3 through the side hole 216. When it is necessary to stop the release of the tear gas tank body 213, just release your hand. At this time, the button 207 is pushed by the first spring 205 on one side of the first clamping ring 204, further driving the second sleeve ring 212 and the tear gas tank body 213 to move in the direction of the button 207, so as to close the tear gas tank body 213.

[0044] like Figure 6 , Figure 7 and Figure 8 As shown, the main adjustment mechanism 3 includes a third housing 301, a turntable 302, a first base 305, a second servo motor 306, a worm 307, a worm wheel 308, a first roller 309, a second base 310, a cable 311, a second roller 312 and a first protrusion 313. The third housing 301 is fixedly connected to one side of the first housing 1, the turntable 302 is movably sleeved inside the third housing 301, the first base 305 is fixedly installed on one side of the turntable 302, and the second servo motor 306 is fixedly installed on one side of the first base 305. The motor 306 and the output end of the second servo motor 306 are fixedly mounted with a worm 307, one side of the worm 307 is meshed with a worm wheel 308, one side of the worm wheel 308 is fixedly sleeved with a first roller 309, the first roller 309 is movably mounted on one side of the second base 310, the second base 310 is fixedly mounted on one side of the turntable 302, one side of the first roller 309 is fixedly connected with a cable 311, one side of the cable 311 is movably connected with a second roller 312, and the end of the cable 311 is fixedly connected with a first protrusion 313;

[0045] The main adjustment mechanism 3 also includes a hose 303, a hard tube 304, a side plate 314, an arc rod 315, an arc spring 316 and a second protrusion 317. The hose 303 is fixedly sleeved inside the transfer tube 217, one side of the hose 303 is fixedly sleeved with the hard tube 304, the side plate 314 is fixedly connected to the top of the transfer tube 217, the inside of the side plate 314 is fixedly connected with the arc rod 315, one side of the arc rod 315 is movably sleeved with the arc spring 316, one side of the arc spring 316 is fixedly connected to the inside of the side plate 314, the other side of the arc spring 316 is fixedly connected with the second protrusion 317, and the second protrusion 317 is fixedly connected to one side of the hard tube 304.

[0046] One side of the hose 303 is fixedly connected to the top of the positioning tube 215 , the hard tube 304 is fixedly connected to one side of the first protrusion 313 , and the second protrusion 317 is movably connected to the inside of the side plate 314 .

[0047] The second roller 312 is movably mounted on one side of the side plate 314 , and the worm gear 308 is movably mounted on one side of the second base 310 .

[0048] It needs to be further explained that: when the rotation angle of the hard tube 304 needs to be adjusted, the second servo motor 306 is started to drive the worm 307 and the worm wheel 308 to engage and transmit, thereby driving the first roller 309 to wind the cable 311. As the cable 311 shortens, the cable 311 drives the first protrusion 313 and the hard tube 304 to move toward the direction of the second roller 312. At this time, the angle of the hard tube 304 is deflected; when the hard tube 304 needs to be reset, it is only necessary to reversely operate the second servo motor 306 to drive the worm 307, the worm wheel 308 and the first roller 309 to rotate in the opposite direction. At this time, the cable 311 is no longer wound around the first roller 309. At the same time, the second protrusion 317 at the bottom of the hard tube 304 is pushed by the arc spring 316, and the cable 311 remains taut until the hard tube 304 is reset.

[0049] like Fig. 9 and Fig.10 As shown, the auxiliary adjustment mechanism 4 includes a connecting rod 401, a linkage plate 402, a limiting rod 403, a second spring 404, a shift block 405, a gear 406 and a rotating shaft 407. The connecting rod 401 is movably installed on one side of the second protrusion 317. The top of the connecting rod 401 is fixedly connected to the linkage plate 402, the interior of the linkage plate 402 is fixedly connected to the limiting rod 403, one side of the limiting rod 403 is movably sleeved with the shift block 405, the bottom of the shift block 405 is fixedly connected to the second spring 404, the bottom of the second spring 404 is fixedly connected to the interior of the linkage plate 402, one side of the shift block 405 is movably clamped with the gear 406, and one side of the gear 406 is fixedly connected to the rotating shaft 407.

[0050] The auxiliary adjustment mechanism 4 also includes a conical nozzle 408, a first damping ring 409, a second damping ring 410, a diaphragm 411, a third damping ring 412 and an atomizing nozzle 413. The conical nozzle 408 is movably connected to one side of the rotating shaft 407, the bottom of the conical nozzle 408 is fixedly connected to the first damping ring 409, the bottom of the first damping ring 409 is fixedly sleeved with the second damping ring 410, the diaphragm 411 is fixedly installed in the middle of the first damping ring 409 and the second damping ring 410, the top of the diaphragm 411 is fixedly installed with the third damping ring 412, and the bottom of the third damping ring 412 is fixedly connected to the atomizing nozzle 413.

[0051] The atomizing nozzle 413 is fixedly installed on the top of the hard tube 304 , and the atomizing nozzle 413 is communicated with the hard tube 304 , the hose 303 , the one-way valve 214 and the tear gas tank body 213 .

[0052] The shift block 405 is movably mounted inside the linkage plate 402 , and the gear 406 is movably mounted on one side of the linkage plate 402 .

[0053] It needs to be further explained that: when it is necessary to adjust the rotation angle of the conical nozzle 408, the block 405 is manually moved in the direction of the limit rod 403. At this time, the block 405 presses the second spring 404 to contract, and at the same time, the block 405 disengages from the gear 406 and no longer restricts the gear 406. Then, the conical nozzle 408 is manually pushed to rotate around the rotating shaft 407. When the conical nozzle 408 rotates to a suitable angle, the block 405 can be released. At this time, the block 405 is pushed by the second spring 404 to mesh with the gear 406 again, limiting the rotation of the gear 406, thereby fixing the conical nozzle 408, and the connecting rod 401 is slidably connected to the inside of the slide groove opened on one side of the second shell 5.

[0054] Working principle and use process of the present invention: During the use of the present invention, when the tear gas tank body 213 needs to be replaced, firstly, the external threaded tube 202 is rotated counterclockwise to separate from the internal threaded ring 201, and the tear gas tank body 213 can be placed into the interior of the first shell 1 through the internal threaded ring 201, and the one-way valve 214 on one side of the tear gas tank body 213 is aligned with the positioning tube 215, and then the external threaded tube 202 is aligned with the internal threaded ring 201 and rotated clockwise to complete the fixing of the internal threaded ring 201 and the external threaded tube 202;

[0055] Next, when it is necessary to release the tear gas in the tear gas tank body 213, by pressing the button 207, the first clamping block 209 can be driven to push the first servo motor 210, the second clamping block 211 and the second sleeve ring 212 to squeeze the tear gas tank body 213, so that the positioning tube 215 completely enters the one-way valve 214. At this time, the one-way valve 214 is opened by the positioning tube 215, and the compressed gas in the tear gas tank body 213 carries the tear gas into the main regulating mechanism 3 through the side hole 216. When it is necessary to stop the release of the tear gas tank body 213, just release your hand. At this time, the button 207 is pushed by the first spring 205 on one side of the first clamping ring 204, further driving the second sleeve ring 212 and the tear gas tank body 213 to move in the direction of the button 207, so as to close the tear gas tank body 213.

[0056] Next, when it is necessary to adjust the rotation angle of the hard tube 304, the second servo motor 306 is started to drive the worm 307 and the worm wheel 308 to engage and transmit, thereby driving the first roller 309 to wind the cable 311. As the cable 311 shortens, the cable 311 drives the first protrusion 313 and the hard tube 304 to move toward the direction of the second roller 312, and the angle of the hard tube 304 is deflected. When the hard tube 304 needs to be reset, it is only necessary to reversely operate the second servo motor 306 to drive the worm 307, the worm wheel 308 and the first roller 309 to rotate in the opposite direction. At this time, the cable 311 is no longer wound around the first roller 309, and the second protrusion 317 at the bottom of the hard tube 304 is pushed by the arc spring 316, and the cable 311 remains taut until the hard tube 304 is reset.

[0057] Finally, when it is necessary to adjust the rotation angle of the conical nozzle 408, the block 405 is manually moved in the direction of the limit rod 403. At this time, the block 405 presses the second spring 404 to shrink. At the same time, the block 405 disengages from the gear 406 and no longer restricts the gear 406. Then, the conical nozzle 408 is manually pushed to rotate around the rotating shaft 407. When the conical nozzle 408 rotates to a suitable angle, the block 405 can be released. At this time, the block 405 is pushed by the second spring 404 to mesh with the gear 406 again, limiting the rotation of the gear 406, thereby fixing the conical nozzle 408.
