The recess 116 can be used to increase the space behind the needle through the first pinhole 130 to prevent moisture or high air humidity from sticking to the needle body, affecting the movement process on the needle hub 100. However, the present invention does not limit the shape, position, and setting of the recess 116, which can be adjusted as needed.

3 is a top plan view of the first pinhole of FIG. 1. Referring to FIG. 1 to FIG. 3 simultaneously, in the embodiment, each of the first pinhole 130 and the second pinhole 140 has a groove communicating with and extending outward from the edge thereof, and the first pinhole 130 Each of the second pinholes 140 expands outwardly through a 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, for example, five grooves 132a to 132e indicated in FIG. 1 and FIG. 3 to transmit through the corresponding grooves 132a. From 132e, it expands outward in a plurality of directions and changes the shape of its outline. Wherein, the through direction of the first pinhole 130 (for example, the Z-axis direction) is different from the extending directions D1 to D5 of the grooves 132a to 132e extending outward (for example, on the XY plane), and the first pinhole 130 The extending directions D1 to D5 of the grooves 132a to 132e are different from each other to be radial, so that the first pinhole 130 is radially expanded outward and changes the shape of its outline.

Furthermore, the projected area of the first pinhole 130 on a reference plane (eg, an XY plane in the XYZ coordinate system) is greater than the projected area of any of the recesses 132a to 132e that it has on the reference plane, and The volume of the first pinhole 130 is greater than the volume of any of the grooves 132a to 132e that it has. In other words, the first pinhole 130 serves to occupy a large space as a main passage through which the needle body passes, and the grooves 132a to 132e serve as a small space added to expand the first pinhole 130 and change the contour of the edge thereof. . In this manner, the grooves 132a to 132e radially extend outward from the edge of the first pinhole 130 with respect to the center O of the first pinhole 130 which is substantially in the shape of a circular hole, so as to be substantially first in the shape of a circular hole. The pinhole 130 is radially expanded outward to change its edge, for example, to change the shape of the contour of its edge to make it petal-like, or to change the curvature of the contour of its edge to make it different from the common circular hole design, but The invention is not limited to the above design, which can be adjusted as needed.

With the above design, when the needle body entrains the liquid through the first pinhole 130 having the design, the grooves 132a to 132e at the edge of the first pinhole 130 can increase the space around the needle body, but does not affect the needle body operation. The direction and progress of the needle to avoid the movement of the needle body by the needle body, and the radial design of the grooves 132a to 132e equidistantly arranged and substantially the same size design can achieve the effect of stabilizing the needle body. However, although the first pinhole 130 of the present embodiment is exemplified by having five grooves 132a to 132e, 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 The above effect can be achieved by at least one groove 132a, as shown in FIG.

In addition, in the present embodiment, all of the first pinholes 130 adopt the above design, and all of the second pinholes 140 also adopt the above design (for example, the second pinhole 140 as shown in FIG. 2), that is, each The second pinhole 140 has five grooves 142 that are substantially the same size and arranged equidistantly, and the grooves 142 extend in a different direction from each other to be radially. In this manner, the recess 142 extends radially outward from the edge of the second pinhole 140 with respect to the center of the second pinhole 140 substantially in the shape of a circular hole, so that the second pinhole 140 substantially presents a circular hole shape. The outer edge is radially expanded to change its edge (for details, reference may be made to the foregoing description of the grooves 132a to 132e, which will not be further described herein). However, although the first pinhole 130 and the second pinhole 140 of the present embodiment have the same design, in other embodiments, the first pinhole 130 and the second pinhole 140 may have different designs (eg, They are grooves each having a different number, size and shape). Moreover, although the embodiment is exemplified by a design in which all of the first pinholes 130 and all of the second pinholes 140 have a single or a plurality of grooves, the present invention is not limited to the above embodiment, as long as the first pinholes 130 and The at least one of the second pinholes 140 has at least one groove design to achieve the above effects.

Referring to FIG. 1 again, a locking hole 1101 and at least a pair of positioning holes 1102 are disposed on the body portion 110. The setting of the locking hole 1101 can be quickly combined with the machine device, and the alignment hole is The 1102 cooperates with a positioning pin (not shown) disposed on the machine equipment, so that the seat body has a alignment effect when locked, and it is not necessary to re-measure the relative position, thereby improving the convenience of replacing the seat body.

In summary, the needle holder provided by the present invention is suitable for use in an automated point system, wherein the body portion and the extension portion connected to each other are correspondingly provided with first pinholes at least partially corresponding to each other for the needle body to pass and be positioned and a second pinhole, wherein at least one of the first pinhole and the second pinhole has at least one groove communicating with and extending outward from the edge thereof, and the first pinhole corresponds to at least one of the second pinhole At least one of the grooves expands outwardly and changes the contour of the edge thereof, for example, to change the shape of the contour of the edge thereof, or to change the curvature of the edge of the contour to be different from the conventional circular hole type pinhole. When the needle body is passed through the pinhole having the design, the groove at 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 employs a plurality of grooves, the grooves may be radially. Thus, the needle holder of the present invention is suitable for reducing the occurrence of sticking when the needle passes through the needle hole when applied to an automated dispensing reagent.
