Initially, as the two clamping rods 15 are clamped into the two clamping grooves 14 positioned below, the two clamping grooves 14 positioned below limit the two clamping rods 15, and further limit the telescopic clamping sleeve 64, so that the problem that the hand rest 5 is loose due to the fact that the telescopic clamping sleeve 64 is mistakenly touched to move upwards can be avoided, when the angle or the height of the hand rest 5 needs to be adjusted, a worker pulls the two handles 16 to move in the directions away from each other at the same time, the two return springs 17 are stretched, the two handles 16 move to drive the two clamping rods 15 to move, the two clamping rods 15 move to be separated from the two clamping grooves 14 positioned below, at the moment, the worker pushes the telescopic clamping sleeve 64 to move upwards and loosen the two handles 16, at the moment, the hollow hexagonal rod 3 can prop against the two clamping rods 15, the two return springs 17 are still in a stretching state, the two clamping rods 15 are driven to move upwards by the upward movement of the telescopic clamping sleeve 64, the two clamping rods 15 are driven to move upwards by the upward movement of the two clamping rods 16 and the two return springs 17, when the two clamping rods 15 move to the same horizontal line with the two clamping grooves 14 positioned above, the hollow hexagonal rod 3 does not support the two clamping rods 15 any more, the two clamping rods 15 are driven to move in the direction of approaching each other by the two return springs 17, the two clamping rods 15 are clamped into the two clamping grooves 14 positioned above, the two clamping grooves 14 positioned above limit the two clamping rods 15, at the moment, a worker can rotate the telescopic clamping sleeve 64, and then drive the hollow hexagonal rod 3 to rotate, and the angle of the hand rest 5 is adjusted; after the angle of the hand rest 5 is adjusted, the staff then pulls the two handles 16 at the same time, so that the two clamping rods 15 are separated from the two clamping grooves 14 positioned above, the two handles 16 are driven to reset by the telescopic clamping sleeve 64, the two clamping rods 15 are enabled to enter the clamping grooves 14 positioned below again, the telescopic clamping sleeve 64 is locked again, if the patient adjusts the position of the hand rest 5, the treatment of hemodialysis can be affected, and as the two clamping rods 15 limit the telescopic clamping sleeve 64, the telescopic clamping sleeve 64 can be unlocked only by pulling the two handles 16 at the same time, and thus the unlocking loosening of the telescopic clamping sleeve 64 caused by pulling the handles 16 by the patient can be effectively prevented.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
