By arranging the magnetic part 72 at the outer side of the spiral groove 71, when the locking device 9 is opened, the magnetic part 72 attracts the metal strip 912 on the locking rope 91, so that the metal strip 912 moves towards the side wall of the spiral groove 71 quickly, the speed of the locking rope 91 far away from the positioning support pipe 3 is increased, and the smooth sliding process of the positioning support pipe 3 is further ensured.
When the adjustable support works, a part is placed on the adjustable support, the gravity of the part is smaller than the elastic force of the first spring 6, when the part contacts the support ball head 4, under the action of manually applying pre-compression force, the positioning support tube 3 slides downwards along the guide sleeve 7, the first spring 6 is compressed in the process, when all the support ball heads 4 contact a workpiece, the manual operation stops applying the pre-compression force, the positioning support tube 3 stops sliding downwards, meanwhile, the winding wheel 82 and the ratchet wheel 85 are driven to rotate under the action of the coil spring 84, the ratchet wheel 85 and the pawl 86 are matched, the first connecting rope 81 is always in a tension state, a worker moves the second connecting rod 96, the rotating sleeve 95 drives the first connecting rod 94 to move, the first connecting rod 94 drives the rotating wheel 93 to rotate, the locking rope 91 is driven to contract, the locking rope 91 is tightly clamped on the positioning support tube 3 in the process, and the locking of the positioning support tube 3 is realized, after the first connecting rod 94 contacts the locking support 92, the rotation of the rotating wheel 93 is further limited, at this time, the locking rope 91 crosses the rotation center of the rotating wheel 93, and then the rotating wheel 93 is rotated under the pulling force of the locking rope 91 to realize self-locking, and further realize self-locking of the locking device 9, when other parts are replaced, the positioning support tube 3 needs to be readjusted, and further the positioning support tube 3 on the support seat 2 needs to return to the original state, the locking device 9 is opened, under the elastic action of the second spring 98, the locking rope 91 adsorbed on the positioning support tube 3 is flicked, and meanwhile, the magnetic part 72 attracts the metal strip 912 on the locking rope 91, so that the metal strip 912 rapidly moves to the side wall of the spiral groove 71, and further smooth when the positioning support tube 3 slides is ensured, the rotating shaft 89 is driven to rotate by rotating the handle 34, and further the rotating shaft 89 drives the pawl 86 to leave the ratchet 85, the supporting tube 3 is positioned to return to the original position under the elastic force of the first spring 6, and then the part to be replaced can be placed.
While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
