The embodiment provides a clamping jaw device which has two functions of clamping articles and rotating articles, and can be applied to various industries including the medical field, for example, in a scene requiring sample movement and rotating code scanning in the medical field.
The jaw apparatus provided by the present invention will now be described. Referring to fig. 1 to 4, in one embodiment, the clamping jaw includes a support base 1, a clamp 2, a telescopic mechanism and a rotating mechanism.
The support 1 serves as a support, which includes but is not limited to a housing structure, a bracket structure, or other structure. In the embodiment shown in fig. 1 to 4, the support 1 is a cylindrical housing structure. The clamp 2, the telescopic mechanism and the rotating mechanism are all directly or indirectly mounted on the support base 1.
The clamp 2 is used to clamp and unclamp an article, which may be a sample with a code strip, for example. The clamp 2 has at least two jaws 22, 23, which jaws 22, 23 are used for clamping an article. The number of the claw bodies 22, 23 is usually two or more, for example, two-finger claw, three-finger claw, four-finger claw, etc.
The telescopic mechanism comprises a first driving member 3, a first transmission structure (including but not limited to a screw nut transmission 6 shown below) and a first connecting member 7, the first transmission structure being mounted on the support base 1. The first driving member 3 is directly or indirectly fixedly connected with the supporting seat 1. The first driving member 3 is in driving connection with a first driving structure (driving connection means an assembly mode capable of realizing transmission of motion and force, and includes fixed connection, movable connection and the like capable of realizing transmission of motion and force), and the first driving structure is in driving connection with the first connecting member 7. The first transmission structure mainly plays a role in motion and force transmission so as to realize that the first driving piece 3 can drive the first connecting piece 7 to stretch and retract. The claw bodies 22, 23 are connected with the first connecting piece 7 in a transmission way, and when the first driving piece 3 drives the first connecting piece 7 to drive and stretch, the first connecting piece 7 drives the claw bodies 22, 23 to clamp and unclamp. In this regard, the first connection 7 and the jaw bodies 22, 23 may be assembled using a structure capable of converting a telescopic movement of the first connection 7 into a relative movement between the jaw bodies 22, 23, as will be described further below.
The rotation mechanism includes a second drive member 4, a second transmission structure (including but not limited to a second gear 10 shown below), and a rotation member 110. The second driving member is directly or indirectly fixedly connected with the supporting seat 1. The second transmission structure is in transmission connection with the second driving piece 4, the rotating piece 110 is in transmission connection with the second transmission structure, the second driving piece 4 drives the rotating piece 110 to rotate, the claw bodies 22 and 23 are arranged on the rotating piece 110 and rotate together with the rotating piece 110, and therefore rotation control of the claw bodies 22 and 23 is achieved.
In order to avoid interference between the two, please refer to fig. 1 to 4, the first connecting member 7 is connected with the first transmission structure in a structure that can both extend and retract along with the first transmission structure and rotate relative to the first transmission structure. In this way, the first connecting piece 7 can not only stretch out and draw back along with the first transmission structure, but also rotate along with the claw bodies 22 and 23 relative to the first transmission structure when the claw bodies 22 and 23 rotate, so that the clamping function and the rotation function of the claw bodies 22 and 23 are finally realized, and the first transmission structure and the first driving piece 3 do not need to rotate along with the claw bodies 22 and 23.
The structure can realize two actions of clamping and rotating on the same clamping jaw, and is simpler in structure, so that the whole size of the clamping jaw is smaller, and the clamping jaw is more convenient to apply to medical environments with abnormal tension in space. On the other hand, the first driving member 3 and the second driving member 4 are directly or indirectly fixedly connected with the supporting seat 1, and cannot displace along with telescopic movement and rotary movement, so that the winding problem can be avoided.
In one embodiment, the clamping jaw can be mainly applied to the field of medical reagent detection, such as clamping and rotating blood samples. In the medical field, the laboratory space is small, and the environment needs to be sterile.

The direction of the telescopic movement is perpendicular to the direction of the reciprocating sliding of the claw bodies 22, 23 on the base 21. For example, in one embodiment, when the jaws are placed vertically, the sliding direction of the jaws 22, 23 is horizontal, and the telescoping direction of the first connector 7 is vertical. Of course, the sliding direction and the telescopic direction will also change correspondingly according to the placement positions of the clamping jaws 22, 23.
