[0056] The following will disclose multiple embodiments of the present invention with the accompanying drawings. For the purpose of clear description, many practical details will be described together in the following description. However, it should be understood that these practical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these practical details are not necessary. In addition, in order to simplify the drawings, some conventional structures and elements will be depicted in a simple schematic manner in the drawings, and the same reference numerals will be used to represent the same or similar elements in all drawings. And if it is possible in practice, the features of different embodiments can be applied interchangeably.

[0057] Unless otherwise defined, all words (including technical and scientific terms) used herein have their usual meanings, which are understood by those familiar with the field. Furthermore, the definitions of the above words in commonly used dictionaries should be interpreted in the context of this specification as consistent with the meanings of the relevant field of the present invention. Unless otherwise clearly defined, these words will not be interpreted as idealized or overly formal.

[0058] Please refer to Figure 1-2 . Figure 1 FIG. 1 is a perspective view of a drilling jig 100 according to an embodiment of the present invention. Figure 2 To illustrate Figure 1 A cross-sectional view along line segment AA, wherein the drill bit 300 has drilled into the workpiece 200 to be drilled. Figure 1-2As shown, a drilling jig 100 includes an abutment plate 110, at least one tube 120, and a plurality of bearings 130. The abutment plate 110 has at least one through hole H1 and a first side 111 and a second side 112 opposite to each other, and the through hole H1 connects the first side 111 and the second side 112. The first side 111 of the abutment plate 110 is configured to abut against a workpiece 200 to be drilled, so that the drilling jig 100 is positioned relative to the workpiece 200 to be drilled. The tube 120 is connected to the second side 112 of the abutment plate 110, and the tube 120 has a space SP therein, and the space SP of the tube 120 connects to the through hole H1 of the abutment plate 110. The bearings 130 are located in the space SP of the tube 120 and connected to the tube 120, and the bearings 130 are separated from each other and have inner holes H2 respectively. The inner hole H2 of the bearing 130 and the through hole H1 of the abutting plate 110 together define a channel CP, and the channel CP is configured to allow the drill bit 300 to pass through to reach the workpiece 200 to be drilled.

[0059] In practical applications, the inner hole H2 of each of the bearings 130 is smaller than the through hole H1 of the abutment plate 110. In addition, the outer diameter of the drill bit 300 is slightly smaller than the inner hole H2 of the bearing 130. Therefore, the bearing 130 can provide a positioning function for the drill bit 300, so that the drill bit 300 can vertically and accurately perform on-site drilling on the workpiece 200 to be drilled. In fact, the workpiece 200 to be drilled can be different machines in the textile industry. In other words, the drilling jig 100 is suitable for use in the textile industry to perform on-site drilling on different machines such as false twisting machines, but the present invention is not limited thereto.

[0060] Furthermore, during the process of the drill bit 300 drilling the workpiece 200, even if the drill bit 300 contacts the bearing 130, the inner ring of the bearing 130 will rotate with the drill bit 300 relative to the outer ring of the bearing 130, so the drill bit 300 is not easy to cause wear or even damage to the bearing 130.

[0061] Please refer to Figure 3 . Figure 3 FIG. 2 is a cross-sectional view of a drilling jig 100 according to another embodiment of the present invention. Figure 3 As shown, the drilling jig 100 further includes at least one first magnetic element 141, and the first magnetic element 141 is disposed on the abutment plate 110, for example, coplanar with the first side 111 of the abutment plate 110. When the workpiece 200 to be drilled is metal, the first magnetic element 141 can be magnetically adsorbed to the workpiece 200 to be drilled, so that the drilling jig 100 can be fixed to the workpiece 200 to be drilled.
