The first spring 216 is sleeved on the outside of the gun head 120. The first spring 216 is used to push the sleeve 213 so that the sleeve 213 is located at the end of the extension shell 211 to protect the gun head 120. The upper and lower sides of the sleeve 213 are fixedly installed with a limit slide 215, and the upper and lower sides of the extension shell 211 are provided with a limit slide groove that matches the limit slide 215. The limit slide 215 allows the sleeve 213 to slide linearly. Grooves are provided on both sides of one end of the sleeve 213 close to the gun body 110, and a first limit card 214 is elastically connected in the groove. Through holes are provided on both sides of the extension shell 211, and push blocks 212 are elastically installed in the through holes. The push blocks 212 are correspondingly arranged with the first limit card 214, and the push blocks 212 are used to push the first limit card 214 so that the first limit card 214 is separated from the clamping connection with the inside of the extension shell 211. The push block 212 is L-shaped, and the push block 212 is located outside the through holes on both sides of the extension shell 211. The first limit card 214 is correspondingly clamped with the through holes on both sides of the extension shell 211. The L-shaped arrangement increases the distance on one side of the push block 212, so that the push block 212 can push the first limit card 214 more conveniently.

[0033] See also Figure 4 and Figure 5A plug assembly 220 is provided on one side of the protective sleeve assembly 210, and the plug assembly 220 includes a fixing hoop 221, a connecting rod 223 and a plug 227. The fixing hoop 221 is fixedly installed on the top of the sleeve 213, and a connecting rod 223 is hinged on one side of the sleeve 213. One side of the connecting rod 223 is limitedly connected to the plug 227. The plug 227 passes through the end of the sleeve 213 and is correspondingly connected to the gun head 120. When the sleeve 213 protects the gun head 120, the plug 227 passes through the sleeve 213 to seal the gun head 120 to prevent the melted glue from flowing out.

[0034] A hinged rod 222 is connected to one side of the top of the connecting rod 223, and the other end of the hinged rod 222 intersects with the fixing hoop 221. A mounting block 224 is fixedly connected to the bottom of the connecting rod 223. A plug rod 225 is slidably mounted inside the fixing hoop 221, and a plug 227 is fixedly mounted on the end of the plug rod 225. The hinged rod 222 is U-shaped, and the connecting rod 223 is C-shaped. The hinged rod 222 and the connecting rod 223 are vertically connected. One end of the plug rod 225 located inside the mounting block 224 is fixedly sleeved with a limiting ring 226, and the tail of the plug rod 225 is sleeved with a second spring 228, and the second spring 228 is located between the limiting ring 226 and the inner wall of the mounting block 224. The mounting block 224 is provided with through holes on both sides, and second positioning cards 229 are arranged in the through holes. The second positioning cards 229 are correspondingly engaged with the limiting ring 226. The upper and lower sides of the second positioning cards 229 are rotatably mounted on both sides of the mounting block 224 through the torsion spring. The hinged rod 222 is flipped so that the hinged rod 222 drives the connecting rod 223 to be located at the end of the sleeve 213. By pressing the end of the second positioning card 229 away from the plug 227, the end of the second positioning card 229 engaged with the limiting ring 226 is tilted. The limiting ring 226 is separated from the limit of the second positioning card 229 and is squeezed by the second spring 228 to penetrate into the sleeve 213 to seal the end of the gun head 120 to prevent the melted glue from flowing out. When not in use, the hinged rod 222 and the connecting rod 223 are flipped and located directly above the gun body 110. At the same time, the connecting rod 223 is C-shaped and corresponds to the top of the gun body 110, which is convenient for folding.

[0035] Working principle: when in the ready-to-use state, the sleeve 213 is located at the front end of the extension shell 211, so that the extension shell 211 is located inside the sleeve 213, and the end of the sleeve 213 will protect the end of the gun head 120. When it is needed, the sleeve 213 is squeezed into the interior of the extension shell 211, so that the sleeve 213 compresses the first spring 216 and is limitedly engaged with the through holes on both sides of the extension shell 211 through the first limit card 214. At this time, the gun head 120 will extend out. After the work is completed, press the push blocks 212 on both sides of the extension shell 211, and the push blocks 212 will squeeze the first limit cards 214 on both sides of the sleeve 213, so that the first limit cards 214 are disengaged from the engagement with the through holes on both sides of the extension shell 211. At this time, the first spring 216 will squeeze the sleeve 213 so that the sleeve 213 continues to be located at the end of the extension shell 211 to protect the gun head 120.
