[0035] In this embodiment, if Figure 1 , Figure 4 and Figure 6As shown, a closed groove is provided on one side of the extension groove on the outer wall of the mounting seat 9, a synchronous groove 21 is provided on one side of the inner wall of the closed groove, a closed plate 20 is slidably connected to the inner side of the closed groove, a synchronous block slidably connected to the synchronous groove 21 is installed on one side of the closed plate 20, a first fixing member 22 is embedded and installed on the other end of the inner wall of the closed groove, a second fixing member corresponding to the first fixing member 22 is embedded and installed on one end of the closed plate 20, a buckle groove is provided on one side of the closed plate 20, and one of the first fixing member 22 and the second fixing member is a first magnet, The other of the first fixing member 22 and the second fixing member is a second magnet, and the magnetic poles of the first magnet and the second magnet are opposite and attract each other. Furthermore, after the two sets of positioning sleeves 4 are locked, the buckle groove can be buckled to cooperate with the synchronous groove 21 and the synchronous block to drive the closing plate 20 to slide inside the closing groove until the second fixing member on the closing plate 20 is pushed to one side of the first fixing member 22, so that the first fixing member 22 and the second fixing member are adsorbed to cover the torsion ring 19 to avoid accidental touch after assembly that causes the positioning sleeve 4 to loosen and fall off.

[0036] In this embodiment, if Figure 1 , Figure 3 and Figure 8 As shown, the connecting mechanism includes a fixing seat 23 installed on the top of one group of positioning sleeves 4, and both ends of the fixing seat 23 are provided with docking grooves, and the inner side of the docking groove is slidably connected to the docking block 24, and the other end of the docking block 24 is installed with a connecting plate 25, and one end of the connecting plate 25 is fixedly connected to one side of the mounting plate 5. Further, the two groups of mounting plates 5 are attached to the fixing seat 23, and the docking block 24 on the connecting plate 25 is allowed to enter the inner side of the docking groove and contact the end of the pressing plate 26. The two groups of inclined surfaces 27 contact and squeeze each other, forcing the pressing plate 26 to slide inside the pressing groove, squeezing the two groups of second springs 30 to retract, until the docking block 24 is completely pushed into the inner side of the docking groove, and the second spring 30 drives the pressing plate 26 to rebound and abut against the protruding end of the docking block 24, locking the position of the mounting plate 5 and the second rubber pad 6.

[0037] In this embodiment, if Figure 1 , Figure 3 and Figure 8 As shown, a pressing groove is provided inside the fixing seat 23 between the two groups of docking grooves, a pressing plate 26 is slidably connected to the inner side of the pressing groove, and inclined surfaces 27 are provided at the opposite ends of the pressing plate 26 and the two groups of docking blocks 24, and a pull rod 28 is installed at the center of one side of the pressing plate 26, one end of the pull rod 28 extends to the outer side of the fixing seat 23 and is rotatably connected to a pull ring 29, and a second spring 30 is installed between the two ends of one side of the pressing plate 26 and the inner wall of the pressing groove, and further, by pulling the pull ring 29 upwards, the pull rod 28 and the pressing plate 26 can be actively retracted to the inner side of the pressing groove, and at this time, the mounting plate 5 can be pulled out together with the second rubber pad 6, so that personnel can replace and maintain them in time.

After it contacts the reset block 13, cooperate with the two sets of first slopes 16 to force it to move and drive the limit plate 12 to squeeze the first spring 14. When the pressing block 8 contacts the squeezing plate 15, the first slope 16 squeezes the second slope, forcing its connecting rod to drive the rebound torsion spring 17 to retract, so that the squeezing plate 15 retracts into the inner side of the squeezing groove until the spring-pressing groove is close to the squeezing groove. , the rebound torsion spring 17 is no longer blocked and drives the extrusion plate 15 to rebound into the inner side of the spring-pressing groove. At this time, the two sets of positioning sleeves 4 are released, and the first rubber pad 10 will rebound a short distance until the pressure block 8 moves back and one end of the extrusion plate 15 abuts against the inner wall of the spring-pressing groove, completing the locking installation. Buckling the torsion ring 19 can drive the pressure rod 18 and the limit plate 12 to move, squeezing the first spring 14, so that the reset block 13 is away from the pressure block 8, and the extrusion plate 15 is dragged away from the inner side of the spring-pressing groove. In this way, the first rubber pad 10 will rebound completely, and the spring-pressing groove on the pressure block 8 is misaligned with the extrusion groove. At this time, loosening the torsion ring 19 will not re-lock. After locking the two sets of positioning sleeves 4, the buckle groove can be buckled to cooperate with the synchronous groove 2 1 and the synchronization block drive the closing plate 20 to slide inside the closing groove until the second fixing piece on the closing plate 20 is pushed to one side of the first fixing piece 22, so that the first fixing piece 22 and the second fixing piece are adsorbed to cover the twisting ring 19 to prevent the positioning sleeve 4 from loosening and falling due to accidental contact after assembly. The two sets of mounting plates 5 are fitted on the fixing seat 23, and the docking block 24 on the connecting plate 25 enters the inside of the docking groove and contacts the end of the pressing plate 26. The two sets of inclined surfaces 27 contact and squeeze each other, forcing the pressing plate 26 to slide inside the pressing groove, squeezing the two sets of second springs 30 to retract, until the docking block 24 is completely pushed into the inside of the docking groove, and the second spring 30 drives the pressing plate 26 to slide inside the pressing groove. The clamping plate 26 rebounds and abuts against the protruding end of the docking block 24, locking the position of the mounting plate 5 and the second rubber pad 6. Conversely, pulling the pull ring 29 upwards can drive the pull rod 28 and the pressing plate 26 to actively retract to the inside of the pressing groove. At this time, the mounting plate 5 can be pulled out together with the second rubber pad 6, which is convenient for personnel to replace and maintain in time. Twisting the knob can drive the threaded rod 33 to rotate. The threads at the two ends of the outer side of the threaded rod 33 are opposite. The two sets of adjustment cylinders 3 cooperate with the translation groove 31 and the translation plate 32 to drive the two sets of positioning sleeves 4 to slide and adjust the position on the surface of the transmission cylinder 1, and the moving translation plate 32 can also slide on the inside of the sliding groove, further ensuring the stability during adjustment.
