The invention discloses a miniature continuum mechanical arm and a spiral line obtaining method thereof, belongs to the technical field of miniature machinery, and aims to solve the problem that high compliance and high rigidity cannot be considered in the prior art. Due to the elastic characteristic of a spiral band, when other parts give out actions or force for driving the whole mechanical arm to bend, a bent arm body can well adapt to driving force and generate expected continuous deformation, and compliance and rigidity are both considered on the premise that the radius of the arm is extremely small; due to the fact that force transmission type contact is carried out at multiple positions between the first spiral belt and the second spiral belt, the action of the shaft arm can be effectively transmitted, and the high-rigidity foundation is met; the shaft arm acts to enable the force transmission contact points between the spiral belts to have the tendency of slipping, mutual slipping between the spiral belts can be avoided through the further arranged anti-slipping structure, the transmission loss of the shaft arm action along the bent arm body is greatly reduced, and then high compliance and high rigidity are both considered on the premise that the arm radius is extremely small.

The utility model relates to optical instrument field discloses a microscope objective lens fine tuning focusing device, including focusing tube, the pipe body of focusing tube is provided with protection mechanism, the protection mechanism includes the multiple outer tubes of fixed connection in the pipe body of focusing tube, the one end away from focusing tube of outer tube all slide connections have inner tube, the inside of outer tube all is provided with spring, the one end away from outer tube of inner tube all fixedly connects with the buffer leather cover, the protection mechanism still includes second protection cover and first protection cover, this focusing device through the cooperation of outer tube, inner tube, spring and buffer leather cover can effectively increase a buffer function when accidentally falling, then through the first protection cover and second protection cover that set up, thereby can effectively protect the rim at focusing tube, through the setting protection mechanism, can effectively reduce the injury when accidentally falling, reduce the precision damage of device because of knock.

The utility model relates to three roll mills technical field especially relates to a three roll mill for coating production, including the body, the body both sides symmetry installs three sets of bearing seat, all rotate and connect in three sets of bearing seat inside roll axle, rotate and connect distance adjusting screw on the body, and distance adjusting screw is connected with bearing seat threadedly, install the drive motor of driving distance adjusting screw rotation on the body, install laser range finder all on the body between three roll axles gap department, install thin film type thermocouple all in the installation cavity in three roll axles. The utility model discloses through laser range finder real time monitoring roll distance change, sends electric signal to drive motor department, drive motor positive rotation drives distance adjusting screw to rotate, and then pulls the bearing seat rear shift, drives slow rear roller or fast front roller to be far from the middle roller, to adjust the roll distance in real time to the surface temperature water cooling reduction after roll axle, and then push the bearing seat forward, reset initial roll distance, can realize dynamic roll distance adjustment, ensure product quality.
