[Embodiment] -6-(4) (4) 1220684 The foregoing and other technical contents, features, and effects of the present invention will be clearly understood in the following detailed description of a preferred embodiment with reference to the accompanying drawings. . As shown in the first, second, and third figures, the preferred embodiment of the strap fastener 9 of the present invention includes a first housing unit 1 above, a second housing unit 2 below, and One fastener 3, one movable member 4, and one ejector 5 between the first and second housing units 1, 2. The first housing unit 1 includes a cover body 11 and a release member 12 assembled together with each other, and a first elastic member 13 arranged between the cover body 11 and the release member 2. The cover 11 has a stepped first notch 1 1 1 at the front end, a through hole 1 1 2 at the center (see the fifth figure), and a second notch 1 1 3 at the rear end. In addition, the cover 11 further has two parallel longitudinal ribs 1 1 4 and a first groove 1 1 5 located between the two ribs 1 1 4 and adjacent to the second gap 1 1 3. The release member 12 has a closed flange 1 2 1 on the outer surface and a recess 122 defined by the closed flange 121, and a longitudinal second groove 1 2 3 at the center of the inner surface. A triangular guide piece 124 extending downward from each side thereof and a convex portion 1 2 5 protruding outward from the ends of the guide pieces 124 respectively. Place one end of the first elastic member 13 in the first groove H5 of the cover 11, and then insert the two guide pieces 124 of the release member 12 into the through holes 1 1 2 of the cover 11 to make the first elasticity The other end of the member 13 is placed in the second groove 123 of the release member 12, and the convex portion 125 at the end of the guide piece 124 is clamped (5) (5) 1220684 to the rib 1 1 4 of the cover body 1 to complete the Combination of the first housing unit 1. Because the protrusions 1 2 5 engage the ribs 1 and 4 of the cover 1, the release member 1 2 cannot be easily separated from the cover 11. Due to the guide lining 2 and the rib lining 4, the release member 12 and the cover body 11 can slide relative to each other longitudinally. Because of the elastic restoring force of the first elastic member 13, in a normal state where the release member 12 is not moved by an external force, the flange 1 2 1 of the release member 12 abuts the through hole 1 1 of the cover 1 1 2 leading edges. When the release member 12 is affected by the external force acting on the concave 8 1 2 or the flange 1 2 1 and is sealed to the cover body 1 1 and moves toward the rear end, the — * elastic member 1 3 is further compressed, and the external force is removed. Then, the release member 12 is moved by the elastic restoring force of the first elastic member 13 to the front of the cover body 1 1 and returns to the position where the flange 1 2 1 abuts the leading edge of the through hole 1 1 2. The second housing unit 2 includes a base 2 1 made of, for example, a plastic material, and a main body member 2 2 made of a high-strength material such as metal. The base 2 1 has raised ribs 2 1 1 at the front and middle sections, two raised posts 2 1 at the rear section, two raised posts 2 1 3 at the front section, and V-shaped recesses located in each of the raised posts 2 1 3 respectively. Ditch 2 1 4. The main body member 22 has a through slot 22 1 at the rear section and two square holes 222, a guide slot 22 3 at the front section, and a support seat 225 formed by two parallel plate bodies 224 in the middle section. Each plate body 224 has A through hole 226 in the center and an eyelet 227 in the corner. The two square holes 222 of the main body member 22 are inserted into the two protruding posts 2 1 2 of the base 21, and the edges of the main body member 2 2 are pressed against the protruding ribs 2 1 1 of the base 21, and the main body 22 is fixed to the base 21 The combination of the second housing unit 2 is completed. In another preferred embodiment, the main body member 22 and the base 2 1 may be integrated into a -8- (6) (6) 1220684 type as the sibling unit. The fastener 3 槪 has a hollow arc shape, and has a hook portion 3 1 ′ located at the lower front end and an abutment portion 3 located at the lower rear end. 2. A shoulder portion 33 located below the middle section, and a through hole 34 located at the center of the side. And a hollow portion 35 formed in the interior and opening upward. The fastener 3 is placed between the two parallel plates 224 of the support seat 22 5, and a first elastic member 61 is inserted into the hollow portion 35 of the fastener 3, and the two ends of the second elastic member 61 are respectively Insert the holes 227 of the two plates 224. Then a pin 6 2 is passed through the through hole of the plate 2 2 4, the through hole 34 of the fastener 3, and the second elastic member 6 i in order, and the fastener 3 and the second elastic member 6 i can be pivoted. The ground is fixed to the support seat 225. The movable member 4 槪 is U-shaped, and has two guide portions 41 located on both sides, a snap-in portion 42 located in the middle to connect the two guide portions 41, and two guide portions 41 and the snap-in portion 42. Commonly defined a notch 43. The lower end of each guide portion 41 has a blind groove 44 closed at one end, respectively. One end of the two third elastic members 63 is respectively inserted into two blind grooves 44 of the movable member 14, and then the movable member 4 is assembled in the second housing unit in such a manner that the notch 43 receives the support seat 225 of the main body member 22. 2. At this time, the other ends of the two third elastic members 63 abut against the two protruding posts 2 1 2 of the base 21, respectively, and the engaging portion 42 of the movable member 4 is located behind the abutting portion 32 of the fastener 3. In addition, the inner surfaces of the two guide portions 41 are adhered to the outer surfaces of the two plate bodies 224 of the support base 22 5 to guide the sliding of the movable member 4 relative to the support base 225. Place the elastic end 5 1 of both sides of the ejector 5 in the groove 2 14 of the base 2 1, and place the front end 5 2 of the ejector 5 in the guide groove -9- (8) of the main body 22 (8) 1220684 When you want to separate the strap connector 8 from the strap fastener 9, simply place your fingers in the recess 1 2 2 or flange 1 2 1 of the release member 12 and push the release member 12 backward Sliding with respect to the cover 11. The two guide pieces 1 24 of the release member 12 push the two guide portions 41 of the movable member 4 to slide the movable member 4 backward until the latching portion 42 of the movable member 4 is released from the resisting portion 32 of the fastener 3, and the fastener 3 It is pivoted under the elastic restoring force of the second elastic member 61, that is, the abutting portion 32 of the fastener 3 is rotated downward, and the hook portion 31 is rotated upward. When the hook portion 31 of the fastener 3 is turned upward to disengage from the opening 8 3 of the tongue piece 8 1, the ejection piece 5 with elastic restoring force pushes against the convex piece 82 of the strap connecting piece 8 to connect the strap. Piece 8 ejects the strap 9. When the finger leaves the release member 12 or no longer exerts force, the release member 12 returns to the flange 1 2 1 forward against the through hole 1 of the cover body 1 by the elastic restoring force of the first elastic member 13. At the same time, the leading edge of 1 2 and the elastic restoring force of the third elastic member 63 push the movable member 4 to slide forward, but the gap between the abutment portion 3 2 of the fastener 3 and the main body member 2 is small or even There is no gap, so the latching portion 42 of the movable member 4 cannot slide under the resisting portion 32 of the fastener 3, that is, the latching portion 42 is blocked by the fastener 3 at the rear end of the fastener 3, so that the fastener The hook portion 31 of 3 is always kept in an open state. However, the above are only preferred embodiments of the present invention. When the scope of implementation of the present invention cannot be limited in this way, that is, simple equivalent changes and modifications made in accordance with the scope of the patent application and the content of the invention specification, All should still fall within the scope of the invention patent.
