One end of the first fixed flexible plate 210 is rotatably connected to one end of the connecting plate 110, one end of the second fixed flexible plate 220 is rotatably connected to the other end of the connecting plate 110, one end of the threaded rod 230 is rotatably connected to the other end of the first fixed flexible plate 210, the nut 240 is threadedly connected to the threaded rod 230, the end of the eccentric pressure plate 250 is rotatably connected to the side wall of the nut 240, and the L-shaped sliding plate 260 is slidably connected to the second fixed flexible plate 220. The top of the L-shaped sliding plate 260 is provided with a fitting groove 261. After the first fixed flexible plate 210 and the second fixed flexible plate 220 are wrapped around the tree trunk, the ends of the first fixed flexible plate 210 and the second fixed flexible plate 220 are brought together. Then, pull the eccentric pressure plate 250 to move the nut 240. The nut 240 drives the threaded rod 230 to rotate, so that the threaded rod 230 passes through the fitting groove 261. Then, rotate the eccentric pressure plate 250 to drive the nut 240 to rotate. The rotation of the nut 240 causes the threaded rod 230 to tighten and tighten the end of the first fixed soft plate 210 with the L-shaped sliding plate 260. Then, move the eccentric pressure plate 250 to drive the end of the eccentric pressure plate 250 to rotate, so that the eccentric wheel at the end of the eccentric pressure plate 250 squeezes and tightens the second fixed soft plate 220 and the L-shaped sliding plate 260, thereby fixing the second fixed soft plate 220 and the first fixed soft plate 210, so that the natural enemy releaser 100 is fixed on the tree trunk. A vertical plate 211 is fixedly installed at the end of the first fixed flexible plate 210. A first rotating groove 212 is opened in the middle of the vertical plate 211. A cylinder 213 is fixedly connected in the middle of the first rotating groove 212. A rotating tube 231 is fixedly installed at the end of the threaded rod 230. The rotating tube 231 is rotatably connected to the cylinder 213. The rotation of the threaded rod 230 drives the rotating tube 231 to rotate on the ruler 223. Nut 240 has symmetrically fixed protrusions 241 on its side wall. The eccentric pressure plate 250 has a second rotating groove 251 in the middle. The end of the second rotating groove 251 is rotatably connected to the protrusion 241. The eccentric pressure plate 250 is moved to make the end of the second rotating groove 251 rotate on the protrusion 241. The connecting plate 110 is fixedly connected to two round tubes 111 at both ends. The first fixed flexible plate 210 is fixedly provided with a first rotating head 214 at its end, which is rotatably connected inside the round tube 111. The second fixed flexible plate 220 is fixedly provided with a second rotating head 221 at its end, which is rotatably connected inside another round tube 111. When the first fixed flexible plate 210 and the second fixed flexible plate 220 are wrapped around the tree trunk, the first rotating head 214 at the end of the first fixed flexible plate 210 rotates on the round tube 111, and the second rotating head 221 rotates on the other round tube 111. Working principle: After the first fixing plate 210 and the second fixing plate 220 are wrapped around the tree trunk, the ends of the first fixing plate 210 and the second fixing plate 220 are brought together, causing the first rotating head 214 at the end of the first fixing plate 210 to rotate on the round tube 111, and causing the second rotating head 221 to rotate on another round tube 111. Then, the eccentric pressure plate 250 is pulled, which drives the nut 240 to move. The nut 240 drives the threaded rod 230 to rotate, and the threaded rod 230 drives the rotating tube 231 to rotate on the ruler 223, so that the threaded rod 230... After passing through the fitting groove 261, the eccentric pressure plate 250 is rotated to drive the nut 240 to rotate. The rotation of the nut 240 causes the threaded rod 230 to tighten, which tightens the end of the first fixed soft plate 210 with the L-shaped sliding plate 260. Then, the eccentric pressure plate 250 is moved to drive the end of the second rotating groove 251 to rotate on the protrusion 241, so that the eccentric wheel at the end of the eccentric pressure plate 250 squeezes and tightens the second fixed soft plate 220 and the L-shaped sliding plate 260, thereby fixing the second fixed soft plate 220 and the first fixed soft plate 210, and fixing the predator releaser 100 to the tree trunk. Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes: The adjusting mechanism 270 includes a square groove 271, an inclined column 272, a pull column 273, and a spring 274. A square groove 271 is formed inside an L-shaped sliding plate 260. An inclined column 272 is slidably connected inside the square groove 271. Two pull columns 273 are fixedly connected to the top of the inclined column 272. There are two springs 274. The two ends of the springs 274 are fixedly connected to the top of the inclined column 272 and the top of the square groove 271, respectively. Pulling the pull column 273 causes the inclined column 272 to slide into the square groove 271 and compresses the spring 274. Releasing the pull column 273 causes the spring 274 to rebound and causes the inclined column 272 to slide out of the square groove 271. The other ends of the two tie rods 273 pass through the top of the square groove 271. A crossbar 275 is fixedly connected between the two tie rods 273. Pulling the crossbar 275 will cause the tie rods 273 at both ends to move. The second fixed flexible plate 220 has a groove 222. The L-shaped slide plate 260 is slidably connected in the groove 222. A ruler 223 is fixedly installed at the bottom of the groove 222. The inclined column 272 engages with the ruler 223. The L-shaped slide plate 260 moves and slides in the groove 222, causing the inclined column 272 to slide up and down along the inclined surface of the ruler 223, and causing the spring 274 to be repeatedly compressed and stretched. When the L-shaped slide plate 260 slides to the appropriate position in the groove 222, the inclined column 272 is engaged in the corresponding groove of the ruler 223, so that the straight surface of the inclined column 272 is in direct contact with the straight surface of the ruler 223, so that the L-shaped slide plate 260 cannot slide back. Working principle: When the diameter of the trunk of the clamp is small, the L-shaped sliding plate 260 slides in the groove 222, causing the inclined column 272 to slide up and down along the inclined surface of the ruler 223, and the spring 274 is repeatedly compressed and pulled. When the L-shaped sliding plate 260 slides to the appropriate position in the groove 222, the inclined column 272 is fitted into the corresponding groove of the ruler 223, so that the straight surface of the inclined column 272 is in direct contact with the straight surface of the ruler 223, so that the L-shaped sliding plate 260 cannot slide back. Then, the predator release device 100 is fixed in the manner described in the above embodiment. When the L-shaped sliding plate 260 needs to slide back, the crossbar 275 is pulled to drive the pull column 273 to move. The pull column 273 drives the inclined column 272 to slide into the square groove 271. When the inclined column 272 is disengaged from the ruler 223, the L-shaped sliding plate 260 is moved back to slide back in the inclined column 272. The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation.
