The specific use steps are as follows:

1. mounting of the entire mechanism

The method comprises the steps that a first carbon fiber tube 3 and a second carbon fiber tube 4 are connected through a tee joint 5 to form a main frame 1, a movable fixing clamping sleeve 10 is sleeved on the first carbon fiber tube 3 when the main frame 1 is assembled, particularly, the movable fixing clamping sleeves 10 are sleeved on the 4 first carbon fiber tubes 3 to ensure that the upper left antagonistic action force, the lower left antagonistic action force, the upper right antagonistic action force and the lower right antagonistic action force of 4 nylon fixing lines 8 can be obtained at the humerus part, the ulna part, the radius part and the metacarpal part of each wing of birds, so that accurate bird postures can be generated, and after the main frame 1 is assembled, 24 nylon fixing lines 8 penetrate into 24 movable fixing clamping sleeves respectively; then slightly screwing the resin screw 9 for fixing; then 5 carbon fiber plates 6 are arranged at the center of a first carbon fiber pipe 3 at the bottom in the whole mechanism, 2 nylon fixing wires 8 penetrate into carbon fiber rings 7 on the carbon fiber plates 6 at the side parts, and resin screws 9 are slightly screwed for fixing;

2. putting birds into parallel mechanism, fixing posture and observing

Firstly, after a body main part of a bird to be observed is placed into a boss 2, a nylon fixing wire 8 on the boss 2 which is preliminarily installed is adjusted to a proper degree of tightness, and then a resin screw 9 which is slightly screwed on the other side is completely screwed;

then the tail ends of the nylon fixing lines 8 are respectively fixed to the proper positions of the wings of the birds, and in order to ensure that the metacarpal bones, the ulna and the radius of the birds and the muscles of the humerus are well protected, the parts of the birds are fixed in a feather mode. 2 pairs of nylon threads 8 are used for fixing the feathers of each part to fix the part; thus, the site can perform antagonism in four directions. As shown in fig. 7, since the palm-affected part is located outside and has thick primary feathers with a relatively high rigidity, the feather fixing function can be achieved by directly tying the nylon fixing thread 8 to the feather of the primary feathers at the part, and therefore, 2 pairs of nylon fixing threads at the left palm-affected part using the method are respectively: a pair of upper and lower antagonistic fixed left primary flyings is formed by a nylon fixed line d84 and a nylon fixed line g 87; the nylon fixed line a81 and the nylon fixed line j810 form a pair of up-down antagonistic fixed left primary filoplume; through the interaction of the two pairs of nylon fixed fine wires, four-direction antagonism can be achieved. The 2 pairs of nylon threads on the right palm part are respectively as follows: a pair of nylon fixing lines r818 and u 821; nylon fixing line o815 and nylon fixing line x 824;

the ulna, radius and humerus of the wings of the birds are not easy to use due to primary flying feather, so the part is fixed in a feather covering mode, and the feather covering tube is small and not easy to fix, so the feather covering of the part is fixed by the aid of the heat-shrinkable tube 12, the feathers of the part need to be trimmed before the heat-shrinkable tube 12 is used, and as shown in fig. 5, the trimmed feathers 14 and the feather-covered trimmed feather roots 13 of the part are obtained; taking the covering feather of the left ulna and radius as an example, the number of the nylon fixing lines used for fixing the part is also 2, a pair of nylon fixing lines e85 and a pair of nylon fixing lines h88 are respectively extended into the heat shrinkable tube 12, and glue is injected for drying and fixing; and the other pair of nylon fixing lines b82 and k811 also penetrate into the corresponding heat-shrinkable tubes, and glue is injected for drying. 2 to the nylon fixation line interact of constituteing like this can play the four-way antagonistic effect to this ulna and radius position, and 2 to the nylon fixation line of left side upper arm bone department are respectively like this: a pair of nylon fixing thread f86 and nylon fixing thread i 89; the nylon fixing lines c83 and the nylon fixing lines l812 form a pair, and the interaction of the 2 pairs of nylon fixing lines can play a role in antagonizing the left humerus part in four directions. The 2 pairs of nylon fixation lines at the right ulna and radius were: the nylon fixed line n814 and the nylon fixed line w823 form a pair; the nylon fixing line q817 and the nylon fixing line t820 form a pair of 2 pairs of nylon fixing lines, and the interaction of the nylon fixing lines can play a role in antagonizing the right ulna and radius parts in the four directions. Finally, the 2 pairs of nylon fixation lines on the right humerus are respectively: the nylon fixing line p816 and the nylon fixing line s819 form a pair; the nylon fixing line v813 and the nylon fixing line m822 form a pair of 2 pairs of nylon fixing lines which are formed in such a way that the interaction can play a role in antagonizing the right humerus part in the four directions;

after complete fixation is finished, the movable fixed cutting sleeve 10 is translated to a proper position, and the resin screw 9 which is not screwed down during installation is completely screwed down; then adjusting a nylon fixing line 8, fixing the wings of the birds to the required positions, and then completely screwing the resin screws 9 which are not screwed tightly during installation;

the birds to be observed are completely fixed in the parallel mechanism, then the posture of the birds can be researched, and the whole device does not use metal and can be used for CT to observe the dynamics problem of the bones of the birds; magnetic resonance scanning to observe changes in bird muscles during movement; and can also be used for shooting to observe the flight attitude problem of birds.
