[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] like Figure 1-4 As shown, a hand support for fixing infusion for children, comprising:

[0031] The arc-shaped hand rest portion 1 has a guide rail groove 11 symmetrically provided thereon for the first sliding portion 3 to slide, the distance between the two first sliding portions 3 is adjustable, and a first adjustable restraint belt 4 is provided between the two;

[0032] The combined wrist supporting part 2 comprises a connecting part 21 inserted into a slide groove at one side of the extending part 22 , and the connecting part 21 is plugged and assembled with the arc-shaped hand supporting part 1 .

[0033] In the above embodiment, the contact surfaces of the extension portion 22 and the connection portion 21 are both provided with rubber damping strips.

[0034] In the above technology, the arc-shaped palm rest portion 1 of the arc-shaped structure can support the palm of the hand, and the spacing between the first sliding portions 3 is adjustable, so as to adapt to the fixing requirements of different palm widths, that is, children of different ages;

[0035] Secondly, the combined wrist support part 2 composed of the extension part 22 and the connection part 21 can be adjusted in length to meet the length of the child's wrist support.

[0036] As another embodiment provided by the utility model, second guide slide parts 5 connected together by a shaft rod 52 are slidably provided on both sides of the extension part 22 , and second adjustable restraining belts 6 are provided on the two second guide slide parts 5 .

[0037] Secondly, one of the second guide sliding parts 5 is threadedly connected with a rotating part 51, and a diamond-shaped piece 511 is provided on the rotating part 51. A silicone ball 521 that moves along the axial direction is slidably provided on the diamond-shaped piece 511 and the shaft rod 52, and the silicone ball 521 is used to be pushed and squeezed by the diamond-shaped piece 511 to the extension part 22 for deformation locking.

[0038] Specific, combined Figure 2 and Figure 3 It can be seen that in the embodiment, by rotating the rotating part 51 clockwise, the long end of the diamond-shaped piece 511 is not in contact with the silicone ball 521, and the contact locking can be achieved at this time. By sliding the second guide part 5, the distance between the second adjustable restraint belt 6 and the arc-shaped hand support part 1 can be flexibly changed. When locking is required, it is only necessary to rotate the rotating part 51 counterclockwise, so that the long end of the diamond-shaped piece 511 contacts the silicone ball 521, and the silicone ball 521 is squeezed onto the extension part 22 and deformed to achieve the locking requirement.

[0039] As another embodiment provided by the present invention, a silicone covering portion 7 with a predetermined number of protrusions 71 on the surface is provided on the arc-shaped palm rest portion 1 .

[0040] As another embodiment provided by the utility model, a toothed track plate 8 symmetrically arranged with respect to the guide groove 11 is provided on the inner side of the arc-shaped palm rest portion 1, and a toothed plate 31 which can engage with the toothed track plate 8 to limit its sliding is symmetrically slidably provided on the first sliding portion 3, and the toothed plate 31 includes a handle portion 32 extending to the outer side surface of the first sliding portion 3.

[0041] Secondly, the first sliding portion 3 is provided with an elastic member 9 for driving the two latching plates 31 to engage with the toothed track plate 8 .

[0042] Specific, combined Figure 4 When it is necessary to adjust the distance between the two first sliding parts 3, press the handle part 32 to bring it closer, and the synchronous tooth plate 31 will disengage from the tooth track plate 8, and then release the handle part 32 again, and it will recover under the action of the elastic member 9, rewriting the engagement limit.

[0043] It should be noted that the two first sliding parts 3 in the embodiment need to be moved separately, the purpose of which is to adapt the child's palm to the position of the arc-shaped palm support part 1, and there is no mandatory requirement that it must be placed coaxially with the wrist.

[0044] As another embodiment provided by the utility model, the arc-shaped palm rest portion 1 is provided with an elastic latch for locking with the inserted connecting portion 21 .

[0045] Specifically, the elastic latch may be a latch pushed by a spring, or a V-shaped elastic plate, or any other elastic locking member known to those skilled in the art.

[0046] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
