[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0030] The present utility model provides the following technical solutions:

[0031] Example 1 discloses a solution to the problem that the use angle of a fixator can be adjusted to facilitate the infusion of children of different ages and improve the infusion comfort of children:

[0032] A positioning plate 1 and a movable plate 2, wherein the movable plate 2 is rotatably installed on the outside of the positioning plate 1, and the positioning plate 1 and the movable plate 2 are in the same horizontal plane;

[0033] It also includes: a first buffer pad 3 and a second buffer pad 4 are respectively attached to the upper sides of the positioning plate 1 and the movable plate 2, and the first buffer pad 3 and the second buffer pad 4 are made of rubber material. The positioning plate 1 has a first mounting plate 11 screwed to its bottom, and a second mounting plate 12 is also slidably installed through a slot at the bottom of the positioning plate 1. Anti-slip pads 13 in an arc shape are respectively arranged in the slots on the inner sides of the first mounting plate 11 and the second mounting plate 12.

[0034] A threaded rod 7 is rotatably installed in a slot inside the positioning plate 1, and the outer end of the threaded rod 7 extends through to the outside of the positioning plate 1. A moving block 8 is threadedly connected through the outside of the threaded rod 7, and the moving block 8 is slidably installed through the bottom inner side of the positioning plate 1.

[0035] A swing rod 9 is movably installed above the moving block 8, and the swing rod 9 is inclined. The upper part of the swing rod 9 is rotatably connected to a mounting seat 10 through a movable shaft, and the mounting seat 10 is screwed to the bottom of the movable plate 2.

[0036] A first elastic band 5 is arranged above the positioning plate 1, and a second elastic band 6 is arranged above the movable plate 2. The first elastic band 5 and the second elastic band 6 have the same structure, and the diameter of the first elastic band 5 is larger than the diameter of the second elastic band 6.

[0037] As Figures 1 - 5 shown, when infusing a child, just place the child's arm on the positioning plate 1 through the first elastic band 5. At this time, the arm placed through can be clamped and positioned by the first elastic band 5. Then place the child's wrist on the movable plate 2 through the second elastic band 6, and then the child's wrist can be clamped and positioned by the second elastic band 6, avoiding the child's shaking during infusion from affecting the subsequent infusion use;

[0038] When the fixator needs to adjust its placement angle for children of different ages during infusion, simply manually rotate the threaded rod 7 to drive the moving block 8 to move inside the positioning plate 1. At this time, the moving moving block 8 will drive the swing rod 9 through the movable shaft to squeeze the mounting seat 10 provided at the bottom of the movable plate 2, and then it can drive the movable plate 2 to flip and swing inside the positioning plate 1, so as to facilitate children of different ages to receive infusion at different angles, thereby improving the infusion comfort of the fixator and having better practicability.

[0039] Embodiment 2, different from Embodiment 1, the fixator can be quickly positioned and installed on the mounting rack of the crib, avoiding the phenomenon of dislocation and offset of the fixator during later use, improving the use stability of the fixator, and discloses:

[0040] A limiting block 14 is rotatably installed in a groove at the top of the second mounting plate 12, and the limiting block 14 is in an arc shape. There is a row of limiting grooves 15 corresponding to the outside of the limiting block 14, and a row of limiting grooves 15 is equally spaced on the inner side of the positioning plate 1. A compression spring 16 is provided in a groove at the inner top of the second mounting plate 12, and the outer end of the compression spring 16 is connected to the limiting block 14.

[0041] A torsion spring 18 is provided in a groove inside the limiting block 14, and the inner side of the torsion spring 18 is wound and connected to a rotating shaft 17. The rotating shaft 17 is rotatably installed inside the limiting block 14, and the outer end of the rotating shaft 17 extends through to the outside of the positioning plate 1.

[0042] As Figures 1 - 7 shown, when the fixator is in cooperation with children for infusion, just place the fixator on the mounting rack of the crib, and then move the second mounting plate 12 to move at the bottom of the positioning plate 1, so that the anti-slip pads 13 provided on the inner sides of the first mounting plate 11 and the second mounting plate 12 are in contact with and connected to the mounting rack of the crib, thereby increasing the friction between the fixator and the crib. While the second mounting plate 12 is moving, the compression spring 16 will automatically eject the limiting block 14 into a row of limiting grooves 15 opened on the inner side of the positioning plate 1 through its own elastic force, and the sliding limit of the second mounting plate 12 can be completed, improving the infusion stability of the fixator;

[0043] Then manually rotate the rotating shaft 17 to drive the limiting block 14 to separate from the limiting groove 15, and then the second mounting plate 12 can be moved back to its original position. Then, through the elastic force of the torsion spring 18 itself, the position of the rotated rotating shaft 17 can be elastically reset for later repeated use, and the operation is more time-saving and labor-saving.
