[0024] like Figs. 1-3 As shown, an animal experimental operating table of this utility model includes a top seat 1 and several limb positioning mechanisms disposed outside the top seat 1. In this embodiment, the top seat 1 is made of a 30*30cm square transparent plastic plate. The four corners of the top seat 1 are chamfered, and the surface of the top seat 1 is flat. A circular first suction cup base 2 is fixed at each of the four corners of the bottom of the top seat 1. On the one hand, it supports the top seat 1, giving it a certain height, which is convenient for the staff to carry out experimental operations. On the other hand, the suction force of the suction cup makes it easy to fix the top seat 1 in the experimental site, so that the top seat 1 is not easy to move during the experiment, increasing the overall stability of the experiment.

[0025] The limb positioning mechanism includes a mounting plate 3 and a column 5. The column 5 is fixed on the mounting plate 3. A second suction cup base 4 is fixed at the bottom of the mounting plate 3. The second suction cup base 4 has the same structure as the first suction cup base 2. Both can use plastic suction cups that can be directly purchased on the market. The mounting plate 3 can be fixed on the test site through the second suction cup base.

[0026] The column 5 includes a first support rod 51 and a second support rod 52 that is slidably disposed within the first support rod 51. The bottom of the first support rod 51 is fixedly mounted on the mounting plate 3, and a third locking member is provided between the first support rod 51 and the second support rod 52.

[0027] In an alternative embodiment, the third locking member comprises a third mounting ring 6 and a third bolt 7. The third mounting ring 6 is fixedly sleeved on the top of the first support rod 51, and the third bolt 7 is located outside the third mounting ring 6 at one end and passes through the sidewall of the third mounting ring 6, the sidewall of the first support plate, and the surface of the second support rod 52 in sequence at the other end, and abuts against the surface of the second support rod 52, thereby forming locking and fixing of the second support rod 52 and the first support rod 51. The third bolt 7 is in threaded connection with the third mounting ring 6 and the first support plate. By tightening or loosening the third bolt 7, the vertical height of the second support rod 52 can be adjusted, so that the overall height of the limb positioning mechanism can be adjusted according to animals of different sizes, the animal can be clamped and fixed, the appropriate height can reduce the possibility of the limb positioning mechanism being touched by the operator, interference with the hands of the operator or experimental tools is avoided, and the influence on the field of view of the operator is small.

[0028] In other embodiments, the third locking member can be a bolt. A threaded hole is formed in the top of the first support rod 51 for the bolt to pass through. The second support rod 52 is arranged in a spaced manner along the arrangement direction and is provided with a plurality of through holes for the bolt to pass through. The bolt passes through the threaded hole and the through hole in sequence, thereby forming connection and fixing of the first support rod 51 and the second support rod 52.

[0029] The top end of the second support rod 52 is fixed with a square crossbar 8 on one side and a counterweight on the other side. The crossbar 8 with a rectangular cross section can ensure that the sliding block 10 does not deviate during sliding on the crossbar 8. The counterweight comprises a support rod 19 and a spherical member 20. The support rod 19 is fixed at the top end of the second support rod 52, and the spherical member 20 is fixed at the free end of the support rod 19, thereby ensuring the overall stability of the limb positioning mechanism. A sliding block 10 is sleeved on the crossbar 8. A first locking member is arranged between the sliding block 10 and the crossbar 8. A support block 11 is fixed on one side of the sliding block 10. A clamping rod 15 is movably arranged on the support block 11. The clamping rod 15 is arranged vertically. A second locking member is arranged between the support block 11 and the clamping rod 15. An arc-shaped clamping plate 16 is fixed at the bottom end of the clamping rod 15.

[0030] In an alternative embodiment, the first locking member is a first bolt 13. A threaded hole is formed in the sliding block 10. A nut seat 12 is arranged at the position of the threaded hole of the sliding block 10. The first bolt 13 passes through the nut seat 12 and the sliding block 10 in sequence and abuts against the square crossbar 8, thereby forming locking and fixing of the crossbar 8 and the sliding block 10. By tightening or loosening the first bolt 13, the position of the sliding block 10 on the crossbar 8 can be adjusted.

[0031] In other embodiments, the first locking member is two square magnets, and the crossbar 8 is an iron rod. By adjusting the position of the sliding block 10 on the crossbar 8, the two magnets are magnetically connected on the same side of the crossbar 8 and located on the left and right sides of the sliding block 10, thereby clamping and fixing the sliding block 10.

[0032] The second locking member comprises a second bolt 14, the support block 11 is located below the cross rod 8, the support block 11 is provided with a through hole for the clamping rod 15 to pass through, the bottom of the sliding block 10 is provided with a threaded hole for the second bolt 14 to pass through in the horizontal direction, the threaded hole is communicated with the through hole, and the second bolt 14 is sequentially passed through the threaded hole, the connecting hole and abuts against the surface of the clamping rod 15, so that the clamping rod 15 and the support block 11 are connected and fixed. By tightening or loosening the second bolt 14, the numerical height of the clamping rod 15 and the arc-shaped clamping plate 16 can be adjusted, so that the limbs, body, head or tail of the animal can be clamped and fixed on the top base 1 as required.

[0033] The inner side of the arc-shaped clamping plate 16 is provided with a soft pad 17, which improves the friction force of the bottom of the arc-shaped clamping plate 16 and can stably clamp and position the limbs of the animal, facilitating experimental operation on the animal.

[0034] The inclined strut 18 is arranged between the cross rod 8 and the stand 5, and the two ends of the inclined strut 18 are fixedly connected with the side wall of the stand 5 and the bottom of the cross rod 8, thereby increasing the structural stability of the cross rod 8.

[0035] In the above embodiment, the free end of the cross rod 8 is fixedly provided with an anti-disengagement column 219 to prevent the sliding block 10 from disengaging from the cross rod 8.

[0036] Working principle:

[0037] The top base 1 is placed on the experimental site and firmly adsorbed on the experimental site through the first suction cup base 2, a proper number of limb positioning mechanisms are selected according to the shape and size of the experimental animal, four limb positioning mechanisms are selected if the experimental animal needs to be fixed on four limbs, and the number of limb positioning mechanisms can be increased correspondingly if the head or tail needs to be fixed. The limb positioning mechanisms are fixed on the experimental site through the second suction cup base 4, the position of the sliding block 10 on the cross rod 8 is adjusted through the first locking member, the clamping rod 15 and the arc-shaped clamping plate 16 are lowered by loosening the second locking member, and the arc-shaped clamping plate 16 can press and abut against the limbs of the animal after being lowered. At this time, the soft pad 17 on the inner side of the arc-shaped clamping plate 16 can quickly fix the limbs of the animal, and different sizes of animals can be clamped flexibly, the overall adaptability of the device is improved, the stability during animal experiment operation is improved, the overall structure is simple, and the cost is low. After the experiment is completed, the top base 1 can be directly washed by being taken off from the experimental site, the clamping rod 15 can be directly washed by being detached from the sliding block 10 through the second locking member, and the washing is convenient.
