The so-called radius template is a thin plate with a set of accurate dimensions containing the radius of the inner and outer arcs. It is used to measure the radius of the physical arc. The general size can be 1-6.5mm, 7-14.5mm and 15-25mm. Three groups.

Please refer to FIG. 4 to FIG. 8 at the same time. Figure 4 shows a schematic view of a second embodiment of the present disclosure. Fig. 5 is a cross-sectional view showing the C-C of Fig. 4. FIG. 6 is a cross-sectional view showing the E-E of FIG. 4 in the present disclosure. FIG. 7 is a cross-sectional view showing the G-G of FIG. 4 in the present disclosure. Figure 8 shows a schematic view of the stretching of the second embodiment of the present disclosure. The fabric assembly 2A of the present disclosure includes a conductive strip 2, and the conductive strip 2 includes an elastic body 21, and the elastic body 21 includes a plurality of buffer portions 211, a plurality of buffers 212 disposed in the plurality of buffer portions 211, and a plurality of extension portions. 213. The buffer portions 211 are alternately disposed on opposite sides of one of the lateral neutral axes 214 of the elastic body 21, and are configured to be circular, but the shape is not limited thereto, and may be any shape. The two ends of each extending portion 213 are respectively overlapped and electrically connected to the buffer portion 211 adjacent to both sides of the lateral neutral axis 214, and the overlap between the extending portion 213 and the buffer portion 211 defines a buffer 212. When the conductive strip 2 is stretched along the lateral neutral axis 214, the extensions 213 can be pivoted relative to each of the buffer portions 211, respectively. In detail, each of the extending portions 213 is electrically connected to the adjacent buffer portion 211 on both sides of the lateral neutral axis 214, and has an angle α between the two adjacent extending portions 213. When the conductive strip 2 is stretched along the lateral neutral axis 214, the two adjacent extending portions 213 are pivoted outwardly about the center of the circular buffer portion 211 to expand outwardly, thereby increasing the angle of the angle α, thereby avoiding conduction. Belt 2 is cracked, broken or broken. The buffer portions 211 at the outermost ends of the elastic body 21 of the conductive strip 2 serve as conductive receiving portions 23 for contacting the electrodes. The material of the conductive strip 2 may be selected from the group consisting of a conductive film, a conductive paste, and a conductive fiber, but is not limited thereto. The fabric assembly 2A further includes a first cloth layer 4, a first bonding layer 5, a second bonding layer 7, and a second cloth layer 6. The first adhesive layer 5 is disposed between the first cloth layer 4 and at least a portion of the conductive tape 2, and the conductive tape 2 is disposed between the first adhesive layer 5 and the second adhesive layer 7, and the second adhesive layer 7 It is disposed between the conductive strip 2 and the second cloth layer 6. In another embodiment, the fabric assembly 2A can selectively exclude the first cloth layer 4 and the first adhesive layer 5, and the extension portion 213 of the conductive tape 2 can be attached by the second adhesive layer 7. In the second cloth layer 6, the buffer portion 211 of the conductive strip 2 except the buffer region 212 can also be attached to the second cloth layer 6 by the second adhesive layer 7, and thus, the buffer portion 211 and the extension portion The buffer 211 overlapping between 213 can still serve as a region for absorbing stress, thereby avoiding the problem of cracking which may be caused by stretching of the conductive strip 2, while maintaining the electrical connection by the contact of the extending portion 213 with the buffer portion 211. Of course, in another embodiment, the cloth assembly 2A may not include the second cloth layer 6 and the second adhesive layer 7 to provide special and varied needs of the wearer. FIG. 5 is a cross-sectional view showing the C-C of FIG. 4, which clearly shows that the buffer portion 211 is bonded to the first adhesive layer 5. 6 shows a schematic cross-sectional view of the EE in FIG. 4, which clearly shows that a buffer 212 is formed between the buffer portion 211 and the extending portion 213. When the cloth assembly 2A is stretched, the buffer portion 211 and the extending portion 213 can be smoothly smoothed each other. The movement acts to form a cushioning so that the cushioning portion 211 and the extending portion 213 are not subjected to stretching to cause cracking. It should be understood that FIG. 6 is a buffer 212 for ease of understanding. Actually, the buffer portion 211 and the extension portion 213 are only in contact with each other and are not physically bonded, thereby maintaining the conduction and buffering effects of the conductive strip. FIG. 7 is a cross-sectional view showing the G-G in FIG. 4 showing the first adhesive layer 5 in accordance with the shape of the extension portion 213. Fig. 8 is a view showing the stretching of the second embodiment of the present invention, that is, the state in which the conductive tape 2 is stretched outward. As can be understood from FIG. 8, when the conductive tape 2 is stretched, the extending portion 213 is pivotable relative to the buffer portion 211, and due to the buffer portion 212 overlapping the extending portion 213 and the buffer portion 211, the extending portion 213 and the buffering portion The portions 211 are only in contact with each other and are bonded to each other, so that the stress at the time of stretching the conductive tape 2 can be relieved by being used as a buffer. As described in the first embodiment, in order to reinforce the adhesion between the layers in the fabric assembly 2A, the cloth assembly 2A may optionally include a reinforcing adhesive layer, which will not be described herein. Please refer to FIG. 9 to FIG. 12 at the same time. Figure 9 shows a schematic view of a third embodiment of the present disclosure. FIG. 10 is a cross-sectional view showing the I-I of FIG. 9 in the present disclosure. Figure 11 is a cross-sectional view showing the K-K of Figure 9 in the present disclosure. Figure 12 shows a schematic view of the stretching of the third embodiment of the present disclosure. The fabric assembly 3A of the present disclosure includes a conductive strip 3, and the conductive strip 3 includes an elastic body 31. The elastic body 31 includes a plurality of buffer portions 311, a plurality of buffer regions 312, and a plurality of extending portions 313. More specifically, each buffer portion 311 can be divided into a first block 3113 and a second block 3115, which can be circular, but the shape is not limited thereto, and the two adjacent extending portions 313 are respectively The first block 3113 and the second block 3115 are integrally formed, and the first block 3113 and the second block 3115 overlap each other to define a buffer 312. When the conductive strip 3 is stretched along the lateral neutral axis 314, the first block 3113 and the second block 3115 are centered on the mass of the buffer portion 311 (ie, the first block 3113 and the second block 3115 are overlapped). The center of mass of the buffer portion 311 is relatively pivoted. That is, when the conductive strip 3 is stretched along the lateral neutral axis 314, the two adjacent extending portions 313 are also pivoted outwardly together with the center of mass of the buffer portion 311 as a center, so that the angle α is increased. The buffer 312, which can perform the pivoting function, can prevent the conductive strip 3 from being cracked, broken or broken. The buffer portions 311 at the outermost ends of the elastic body 31 of the conductive strip 3 serve as conductive receiving portions 33 for contacting the electrodes. The material of the conductive strip 3 is selected from the group consisting of a conductive film, a conductive paste, and a conductive fiber. The fabric assembly 3A further includes a first cloth layer 4, a first bonding layer 5, a second bonding layer 7, and a second cloth layer 6. The first adhesive layer 5 is disposed between the first cloth layer 4 and at least a portion of the conductive tape 3. The conductive tape 3 is disposed between the first adhesive layer 5 and the second adhesive layer 7. The second adhesive layer 7 is disposed between the first adhesive layer 5 and the second adhesive layer 7. It is disposed between the conductive strip 3 and the second cloth layer 6. In another embodiment, the fabric assembly 3A can selectively exclude the first cloth layer 4 and the first adhesive layer 5. At this time, the remaining portion of the conductive tape 3 except the buffer zone 312 can pass through the second adhesive layer. The bonding layer 7 is attached to the second cloth layer 6, and since the first block 3113 and the second block 3115 overlap each other in the buffer zone 312 and do not adhere to each other, there is still a relatively movable space. Thereby, the electrical connection is maintained and the buffering effect is provided; of course, in another embodiment, the cloth assembly 3A may not include the second cloth layer 6 and the second adhesive layer 7 to provide different and varied wearers. Special needs. FIG. 10 is a cross-sectional view showing the I-I of FIG. 9 in which the first block 3113 and the second block 3115 of the buffer portion 311 are stacked. Figure 11 shows a cross-sectional view of the K-K in Figure 9 showing the buffer 312 formed by the first block 3113 and the second block 3115. It should be understood that the buffer region 312 is substantially a region where the first block 3113 and the second block 3115 overlap each other but not adhere to each other, so that it still has to maintain the characteristics of electrical connection and buffering, and here The buffer 312 is drawn for clarity. Fig. 12 is a view showing the stretching of the third embodiment of the present invention, that is, the state in which the conductive tape 3 is stretched outward. Figure 13 is a view showing another aspect of the third embodiment of the present disclosure. Figure 14 is a perspective view showing another aspect of the third embodiment of the present disclosure. The conductive strip 3 in the embodiment of FIG. 9 is different from the conductive strip 3' in the embodiment of FIG. 13 in that the extension portion 313' of FIG. 13 and the first block 3113' (or the second block 3115') are The rectangular shape is such that the buffer portion 311' is a "quadruple" first block 3113' and a "quadrilateral" second block 3115'.
