The recess 116 can be used to increase the space after the needle body passes through the first needle hole 130 to prevent the needle body from sticking due to moisture or high air humidity, which affects the movement process on the needle seat 100. However, the present invention does not limit the shape, position and arrangement of the recess 116, which can be adjusted according to requirements.

FIG. 3 is a schematic top view of the first pinhole of FIG. 1 . Please refer to FIG. 1 to FIG. 3 at the same time, in this embodiment, each of the first pinhole 130 and the second pinhole 140 has a groove communicating with it and extending outward from its edge, and the first pinhole 130 Each of the second pinholes 140 expands outward through the corresponding groove and changes the contour of its edge. Taking the first pinhole 130 as an example, the first pinhole 130 has a plurality of grooves, such as the five grooves 132a to 132e marked in FIG. 1 and FIG. 3 , so as to penetrate the corresponding groove 132a To 132e expands outward in multiple directions and changes the shape of its outline. Wherein, the penetrating direction of the first pinhole 130 (eg, the Z-axis direction) is different from the extending directions D1 to D5 (eg, on the XY plane) of the grooves 132a to 132e it has extending outward (eg, on the XY plane), and the first pinhole 130 The extending directions D1 to D5 of the grooves 132 a to 132 e are radially different from each other, so that the first pinhole 130 expands radially and changes the shape of the contour.

More specifically, in this embodiment, the grooves 132a to 132e of the first pinhole 130 have substantially the same size, and the included angle between any two adjacent ones of the extending directions D1 to D5 of the grooves 132a to 132e The same, that is, the grooves 132a to 132e are equidistantly arranged around the edge of the first pinhole 130 . Furthermore, the projected area of the first pinhole 130 on a reference plane (eg, the XY plane in the XYZ coordinate system) is greater than the projected area of any one of the grooves 132a to 132e it has on the reference plane, and The volume of the first pinhole 130 is larger than that of any one of the grooves 132a to 132e it has. In other words, the first pinhole 130 is used to occupy a larger space as the main passage for the needle body to pass through, and the grooves 132a to 132e are used to expand the first pinhole 130 and change the contour of its edge to increase the smaller space . In this way, the grooves 132a to 132e extend radially outward from the edge of the first pinhole 130 based on the center O of the first pinhole 130 that is substantially circular, so that the substantially circular first The pinhole 130 expands radially outward to change its edge, for example, to change the shape of the contour of its edge to make it appear petal-like, or to change the curvature of the contour of its edge to make it different from the common round hole design, but this The invention is not limited to the above-mentioned designs, which can be adjusted according to requirements.

With the above design, when the needle body entrains the liquid through the first needle hole 130 with the above-mentioned design, the grooves 132a to 132e on the edge of the first needle hole 130 can increase the space around the needle body without affecting the operation of the needle body. In order to avoid sticking to the needle body and affecting the movement of the needle body, the radial design of the grooves 132a to 132e arranged at equal distances and the design of substantially the same size can achieve the effect of stabilizing the needle body. However, although the first pinhole 130 in this embodiment has five grooves 132a to 132e as an example, the present invention does not limit the size, arrangement and number of the grooves 132a to 132e, as long as the first pinhole 130 has five grooves 132a to 132e. At least one groove 132a can achieve the above effect, as shown in FIG. 4 .

In addition, in this embodiment, all the first pinholes 130 adopt the above-mentioned design, and all the second pinholes 140 also adopt the above-mentioned design (for example, the second pinholes 140 as indicated in FIG. 2 ), that is, each The second pinhole 140 has five grooves 142 with substantially the same size and equidistantly arranged, and the extending directions of the grooves 142 are different from each other and present radial shapes. In this way, the grooves 142 extend radially outward from the edge of the second pinhole 140 based on the center of the second pinhole 140 , which is substantially a circular hole, so that the substantially circular second pinhole 140 It expands radially outward to change its edges (for details, please refer to the above descriptions about the grooves 132a to 132e, and details are not repeated here). However, although each of the first pinhole 130 and the second pinhole 140 in this embodiment has the same design, in other embodiments, the first pinhole 130 and the second pinhole 140 may have different designs (eg, are grooves each having a different number, size and shape). In addition, although the present embodiment takes a design in which all the first pinholes 130 and all the second pinholes 140 have a single or multiple grooves as an example, the present invention is not limited to the above-mentioned embodiment, as long as the first pinhole 130 and the At least one of the second pinholes 140 is designed with at least one groove, so that the above-mentioned effects can be achieved.

Please refer to FIG. 1 again, a locking hole 1101 and at least a pair of alignment holes 1102 are provided on the body portion 110 . 1102 cooperates with a positioning pin (not shown in the figure) set on the machine equipment, so that the seat body has the effect of alignment when it is locked, and the relative position does not need to be measured again, which improves the convenience of replacing the seat body.

To sum up, the needle holder provided by the present invention is suitable for automatic point making, wherein the main body part and the extension part connected to each other are correspondingly provided with at least some of the first needle holes corresponding to each other for the needle body to pass and locate, and The second pinhole, wherein at least one of the first pinhole and the second pinhole has at least one groove that communicates with it and extends outward from its edge, and at least one of the first pinhole and the second pinhole passes through the corresponding At least one of the grooves expands outward and changes the contour of the edge, for example, changing the shape of the contour of the edge, or changing the curvature of the edge of the contour, so that it is different from the common round hole type pinhole. When the needle body carries liquid through the pinhole with the design, the grooves on the edge of the pinhole can increase the space around the needle body to avoid sticking due to moisture in the pinhole. When at least one of the first pinhole and the second pinhole adopts a plurality of grooves, the grooves may be radial. In this way, the needle hub of the present invention is suitable for reducing the problem of sticking when the needle body passes through the needle hole when it is applied to automated dispensing of reagents.
