The eighth figure is a side cross-sectional view of the creation of the belt. First, please refer to the second and third figures. The belt pulley (20) provided by the county mine _Wei Shi has a cylinder (21), and at least the end of the cylinder (21) is provided with a clamp (30). ). In practice, it is preferable to install a clamp at each end of the belt pulley. In the following, the clamp is installed at one end of the belt wheel, and the same configuration is used when both ends of the grinder are provided with a fire. The cylinder (21) is a hollow cylinder, and a rotating shaft (four) is arranged at the center, so as to be mounted on the belt machine to be driven. The belt wheel (4) is provided with a slot (24) at least at the periphery of the end. Referring to Figures 4 and 5, the central controller (3〇) includes a body (4〇), a cooling sheet (50) and a shrapnel (60). The end of the body (40) is a flat connecting portion (42), and the other end is a cool end (44); two tabs (45) are respectively disposed on the two sides of the clamping end (44) . a pivot (46) pivotally connecting the lugs (52) on both sides of the inflamed piece (50) and the two tabs (45) of the body (4), so that the clip (40) is opposite to the body (32) Pivot, clip and swing. The elastic member (47) is a torsion spring sleeved on the pivot shaft (46), and the two ends (48) (49) respectively abut against a tab (45) of the body (40) and the clip (50), the elastic energy is such that the clip (5〇) is kept swinging toward the body, so that one end edge (54) of the clip is elastically closed with the clamping end (44) of the body. The shrapnel (60) has two bodies (62) (64) forming a predetermined included angle. In the present embodiment, the two pieces of the body are in a shape of a shape, but not limited thereto. For example, the two pieces may have a 'shaped configuration. The first body (62) of the elastic piece (60) is fixed to the connecting portion (42) of the body (40) by a screwing member (65), welded, riveted or equivalent. If the elastic piece is connected to the body by a screwing component (65) or by a riveting component, a plurality of bumps (66) may be punched on the body (62) and the connecting portion (42) to improve the bonding. So that the shrapnel (6〇) will not shake the M332001. When assembled, the clamp (30) is fixed to the inner wall surface of the cylinder (21) by a plurality of screwing members (68) by the second body (64) of the elastic piece (60), as in the second, Three pictures. The mounting of the clamp (3〇) corresponds to the slot. The body (4〇) and the clip (5〇) are suspended in the cylinder (21), and the elastic piece (60) provides elastic energy of the clamp which can be elastically displaced in the cylinder. * Please refer to the sixth figure. When used, the outer surface of the belt wheel (2G) is wound with a sand belt (7〇), and the belt is wound obliquely from the cylinder (21) to the other end. . Thereafter, φ cuts the end (72) of the belt (7 〇) into a narrow width and penetrates into the cylinder from the groove (24) of the cylinder to clamp the sand with the clamp (30) band. Please refer to the seventh @, when the belt is to be clamped, the operator pulls the clip (5〇) outward with the finger, as shown in the F direction. This force will produce two twists at the same time, one of which is: the clip (50) will be pulled open to open its end edge (54) away from the body's cool end (44), and in between Form __(74). The second is that the force is applied to the elastic piece (60) at the same time, so that the elastic piece is pressed, and the body (62) and the body (4〇) of the elastic piece are elastically oscillated toward the outer circumference of the cylinder (4). • In the state of the seventh figure, the end of the belt (7〇) can be inserted into the clamper's '''.” After the sanding belt is penetrated, the release of the pulling clip (50) is applied. Force, the clip is subjected to the action of the elastic element (4) to the body (4〇) to swing and reset its end edge (4) and the clamping end (44) of the body is closed 'clamp the belt' as shown in the eighth figure.
