Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: outpatient service blood sampling arm fixing device, press area 1 including fixed connection on base plate 10 and the base plate 10, second spout 12 has been seted up on the base plate 10, sliding connection has second slider 11 in the second spout 12, 11 internal rotations of second slider are connected with two live-rollers 13, two live-rollers 13 with press 1 free end butt in area, 11 side fixedly connected with side slide of second slider 2, it is connected with pawl 3 and ratchet 4 to rotate through the pivot on the side slide 2, it is connected with threaded rod 7 to close through the screw soon in the side slide 2, it slides on 6 directions of first spout to drive side slide 2 when making threaded rod 7 rotate.
Specifically, as shown in fig. 1, the ratchet wheel 4 is fixedly connected with the rotating shaft of the rotating roller 13, and the ratchet wheel 4 is clamped with the pawl 3, so that the rotation of the rotating roller 13 is limited in a single direction through the clamping of the ratchet wheel 4 and the pawl 3.
