The working principle is as follows: firstly, the limb fixing auxiliary frame for the radiobiological experiment is arranged at a use position and is operated in the following way:
according to fig. 1-10, the position of the support rod 5 and the sleeve 7 is adjusted according to the volume of the living being in the following way:
the transverse screw 11 is rotated to enable 2 connecting blocks 17 on the transverse screw to be close to or far away from each other so as to adjust the distance between the transverse supporting rods 5, the longitudinal screw 4 is driven to move in the moving process of the connecting blocks 17, the stability of the connecting blocks 17 in the moving process is guaranteed through the first sliding grooves 2 and the first sliding blocks 3, then the longitudinal screw 4 is rotated to enable 2 supporting rods 5 on the longitudinal screw 4 to be close to or far away from each other so as to adjust the distance between the longitudinal supporting rods 5, the connecting rod 12 can stretch and move on the supporting tube 13 in the longitudinal position adjusting process of the supporting rods 5, and the position of the supporting rods 5 can be conveniently adjusted by adjusting the distance between the transverse direction and the distance between the longitudinal direction of the supporting rods 5 so that the distance between the supporting rods 5 can meet the use requirements of organisms;
through rotating the adjusting sleeve 8, the pressing block 25 on the inner side of the adjusting sleeve 8 synchronously rotates, and further the positioning rod 26 gradually springs outwards under the action of the first compression spring 28, and further the positioning rod 26 is separated from the positioning hole 6 on the supporting rod 5, so that the connection between the sleeve 7 and the supporting rod 5 is disconnected, and then the sleeve 7 slides on the outer side of the supporting rod 5, after the sleeve is adjusted to a proper position, the adjusting sleeve 8 is loosened, the adjusting sleeve 8 reversely rotates under the action of the torsion spring 24, and therefore the purpose that the pressing block 25 gradually extrudes the positioning rod 26 is achieved, so that the positioning rod 26 is clamped and connected with the positioning hole 6 at the proper position, and the position of the sleeve 7 is fixed;
then, when the connecting rope 9 needs to be wound or released, the rope winding rod 16 can be pulled outwards and rotated, so that the connecting rope 9 is wound or released by the rope winding rod 16, the position of the fixing mechanism 10 meets the use requirement, when the rope winding rod 16 is pulled outwards, the extension spring 22 can be extended, the female tooth 20 and the sub-tooth 21 are disengaged and connected, and after the rotation, the female tooth 20 and the sub-tooth 21 can be engaged again through the resetting of the extension spring 22, so that the rotation of the rope winding rod 16 is limited;
finally, the limb end of the living being is stretched into the pipe body 101 on the fixing mechanism 10, in the stretching process, the outer pressure cover 104 is pushed and pressed, the second compression spring 107 is compressed, when the limb end stretches into the pipe body 101, the limit block 103 is jacked to rotate, after stretching, the limit block 103 resets under the action of the reset rotating shaft 106, the joint of the limb end is clamped, the damage to the joint of the limb end can be avoided through the rubber end part on the limit block 103, the outer pressure cover 104 is loosened, the outer pressure cover 104 resets under the action of the second compression spring 107, the outer side of the limit block 103 is conveniently shielded, the limit block 103 can be prevented from bouncing, and the limb end can be stably connected;
after the limbs of the living being are fixed, the living being is bound to struggle, and in the process of struggling, the second sliding block 15 is driven to slide in the second sliding groove 14, so that the left limb and the right limb are pulled to each other, and the living being can be limited to be struggled from the auxiliary frame by the force of the living being;
thereafter, radiobiological experiments can be performed, and those not described in detail in this specification are within the skill of the art.
It is to be understood that the terms "central," "longitudinal," "lateral," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in the orientations and positional relationships indicated in the drawings for the purpose of convenience and simplicity of description, and do not indicate or imply that the referenced devices or components must be in a particular orientation, constructed and operated in a particular orientation, and are not to be considered limiting of the scope of the present invention.
