[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] Example 1, by Figures 1-6 The present invention includes a mounting frame 1, a connecting column 5 fixedly mounted on the top of the mounting frame 1, two inner tubes 8 symmetrically sleeved on the mounting frame 1, each inner tube 8 having a nut 6 at its top end, both nuts 6 being located on the top of the mounting frame 1, and an outer tube 7 movably sleeved on the outer side of each inner tube 8. An adjustment mechanism 2 is mounted on the mounting frame 1, a drive mechanism 3 is mounted on the adjustment mechanism 2, and a fixing mechanism 4 is mounted on the drive mechanism 3.

[0030] In Embodiment 2, based on Embodiment 1, the adjusting mechanism 2 includes a horizontal plate 201 fixed to the outside of the mounting frame 1. A bottom ring 205 is fixedly installed at the bottom of the horizontal plate 201. A connecting frame 209 is fixedly installed between the two outer tubes 7. The connecting frame 209 is located below the horizontal plate 201. A lifting plate 2010 is provided between the connecting frame 209 and the horizontal plate 201. A U-shaped round rod 208 is fixedly installed at the bottom of the lifting plate 2010. The U-shaped round rod 208 passes through the connecting frame 209 and moves with the connecting frame 209. The lifting plate 2010 and the connecting frame 209 are symmetrically and fixedly connected by two springs 207. Both springs 207 are sleeved on the outside of the U-shaped round rod 208. A movable column 204 is fixedly installed on the top of the lifting plate 2010. The movable column 204 passes through the bottom ring 205 and the horizontal plate 201 and is movably connected to both. A spring 206 is fixedly connected between the bottom ring 205 and the lifting plate 2010. The spring 206 is sleeved on the outside of the movable column 204. The horizontal plate 2010... A mounting frame 2011 is fixedly installed at the bottom of the 1. A top block 203 is fixedly installed at the top of the movable column 204. A vertical plate 202 is fixedly installed at the bottom of the top block 203. The bottom of the vertical plate 202 passes through the horizontal plate 201 and extends into the interior of the mounting frame 2011. The vertical plate 202 is movably connected to the horizontal plate 201. A double-acting screw 2015 is rotatably connected inside the mounting frame 2011. Two threaded sleeves 2014 are symmetrically threaded on the outer side of the double-acting screw 2015. The outer side of the vertical plate 202 is symmetrically rotatably connected. There are two drive rods 2012, both of which are located inside the mounting frame 2011. The ends of the two drive rods 2012 away from the upright plate 202 are rotatably connected to the tops of two threaded sleeves 2014. Guide blocks 2016 are fixedly installed on the outer side of each of the two threaded sleeves 2014. A guide rod 2013 is fixedly connected inside the mounting frame 2011. The guide rod 2013 is arranged parallel to the bidirectional lead screw 2015. The two guide blocks 2016 are movably sleeved on the outer side of the guide rod 2013.

[0031] First, rotate the two-way lead screw 2015. Since the two guide blocks 2016 are movably sleeved on the outside of the guide rod 2013, they drive the two threaded sleeves 2014 to move horizontally. Then, through the two drive rods 2012, they drive the upright plate 202 to move longitudinally. At this time, the top block 203 drives the movable column 204 to move longitudinally, and drives the lifting plate 2010 to move longitudinally. At the same time, the first spring 206 and the two second springs 207 deform. Finally, the shock absorption of the shock-absorbing fork is adjusted.

[0032] In Embodiment 3, based on Embodiment 1, the drive mechanism 3 includes a mounting sleeve 301 fixed to the middle of the outer side of the guide rod 2013. The mounting sleeve 301 is fixed to the inner bottom wall of the mounting frame 2011 and is located between two guide blocks 2016. A rotating shaft 304 is rotatably connected to the side of the mounting sleeve 301 near the bidirectional lead screw 2015. A bevel gear 308 is fixedly mounted on the end of the rotating shaft 304 away from the mounting sleeve 301. A support block 307 is fixedly mounted on the inner bottom wall of the mounting frame 2011 and is located between the bidirectional lead screw 2015 and the mounting sleeve 301. 304 passes through the support block 307 and is rotatably connected to the support block 307. A bevel gear 309 is fixedly installed on the outside of the double-acting screw 2015. The bevel gear 309 meshes with the bevel gear 308. A drive shaft 302 is rotatably connected to the top of the mounting sleeve 301. The top of the drive shaft 302 passes through the horizontal plate 201 and is fixedly installed with a turntable 303. The drive shaft 302 is rotatably connected to the horizontal plate 201. A bevel gear 305 is fixedly installed on the outside of the drive shaft 302. A bevel gear 306 is fixedly installed on the outside of the rotating shaft 304. The bevel gear 306 meshes with the bevel gear 305.

[0033] First, the turntable 303 is rotated, which drives the drive shaft 302 to rotate, and in turn drives the first bevel gear 305 to rotate. Since the first bevel gear 305 is meshed with the second bevel gear 306, it drives the rotating shaft 304 to rotate. Through the support of the support block 307, the rotating shaft 304 can rotate stably. At the same time, it drives the third bevel gear 308 to rotate. Since the third bevel gear 308 is meshed with the fourth bevel gear 309, the bidirectional lead screw 2015 is finally rotated.

[0034] In Embodiment 4, based on Embodiment 1, the fixing mechanism 4 includes a top frame 401 fixed to the top of the horizontal plate 201. The top frame 401 is sleeved on the outside of the vertical plate 202. The drive shaft 302 is located on the side of the top frame 401 away from the vertical plate 202. A U-shaped round rod 402 is fixedly installed on the side of the top frame 401 near the drive shaft 302. A sliding plate 405 is movably sleeved on the outside of the U-shaped round rod 402. A locking gear 404 is fixedly installed on the side of the sliding plate 405 away from the top frame 401. An external gear 403 is fixedly installed on the outside of the drive shaft 302. The external gear 403 meshes with the locking gear 404. A connecting plate 406 is fixedly installed on the sliding plate 405. A limiting plate 409 is fixedly installed on the side away from the sliding plate 405. A plug rod 4010 is fixedly installed on the side of the limiting plate 409 near the upright plate 202. The upright plate 202 is provided with equidistant holes 4011 on the side near the limiting plate 409. The inner diameter of each plug hole 4011 is equal to the outer diameter of the plug rod 4010. The end of the plug rod 4010 away from the limiting plate 409 is inserted into the corresponding plug hole 4011. A screw rod 408 is fixedly installed on the side of the top frame 401 near the limiting plate 409. The limiting plate 409 is movably sleeved on the outside of the screw rod 408. A nut 407 is provided on the side of the limiting plate 409 away from the top frame 401. The nut 407 is threaded onto the outside of the screw rod 408.

[0035] First, the limiting plate 409 slides along the screw 408. The connecting plate 406 drives the slide plate 405 to slide along the U-shaped round rod 402, and drives the locking gear 404 to move until it meshes with the external gear 403. At this time, the end of the insert rod 4010 away from the limiting plate 409 is inserted into the corresponding insertion hole 4011. Then, the nut 407 is put on the outside of the screw 408 and tightened, thereby fixing the drive shaft 302 to prevent it from rotating arbitrarily. At the same time, the upright plate 202 is fixed to prevent it from moving longitudinally. Finally, the lifting plate 2010 is prevented from moving by double fixing.
