In this locked state, a space 14 is formed between the front end 1 a of the claw and the lower surface 13 of the base end portion 13 to accommodate the plate thickness of the upper panel 4. The through holes 23 can rotate freely. As described above, the female connector 2 is fixed to the top plate 3, and the male connector 1 is fastened to the other plate, that is, the upper panel 4, so that the two connectors face each other from up and down, and the male connector When the inserting part 5 of the connecting body 1 is aligned with the fitting recessed part 16 of the female connecting body 2 and the two connecting bodies 1 and 2 are pressed against each other, as described above, the inserting part 5 can be reduced in diameter, so It is a combination of the two bodies while receiving the resistance of the male and female screws 7, 17 while fitting. Although the combination of the two bodies completed by this pressing is incompletely combined, the male and female screws 7, 17 are engaged with each other, so a state of temporary engagement is formed, and the top plate 3 can be temporarily fixed to the On the upper panel 4. In addition, the mutual pressing when the two connecting bodies 1 and 2 are combined may be performed by pressing the upper surface of the top plate 3. In addition, a plurality of fasteners may be arranged below the top plate and the upper plate, and when they are combined, the entire top plate 3 is evenly pressed, so that all of them are temporarily combined at the same time. After obtaining the temporarily coupled state as described above, then place a tool such as a screwdriver on the retaining portion 15 of the retaining shaft portion 6 protruding toward the lower side of the upper panel 4, and then perform a twist operation to make the entire male connector 1 When rotating, the male screw 7 fastened to the female screw 17 can be locked to fix the inserting part 5 to the inserting part 5.

314211.ptd Page 15 1221509 V. Description of the invention (ίο) The recessed portion 16 is closed, and the combination of the two connecting bodies 1, 2 is achieved, so that the top plate 3 is firmly fixed on the upper plate 4. When the male screw 7 is tightened, the inserting portion 5 will enter, and at the same time, the protrusion 18 of the fitting concave portion will enter the front end portion of the hollow portion 10 and close here. Therefore, the originally shrinkable inserting portion 5 can no longer be used. Reducing the diameter can ensure the screwed state of the male screw 7 and the female screw 17 and ensure a stable combined state. As described in detail above, the buckle of the present invention can fit the female connecting body 2 to the fixing portion 21 of the top plate and fix the locking shaft portion 6 of the male connecting body 1 to the upper panel. The operation of locking the through hole 2 of 4 and the pressing of the two to achieve the combination of the two, after that, as long as the male connector 1 is twisted, a stable and stable bonding state can be obtained. Therefore, compared with the conventional method of fixing with metal nuts and bolts, it is possible to perform effective fixing by an easier operation. However, the above description is for the case where the male and female joints 1 and 2 formed separately are used, but the present invention may also be formed in a state where the two bodies are first combined and then directly used for the connection of the plate. The use method in this combined state is as long as the female connector 2 is mounted on the fixed portion 21 of the top plate 3, and the entire fastener is first installed under the top plate 3, and then the top plate 3 is covered on the top plate 4. By inserting the locking shaft portion 6 of the male connector 1 into the locking through hole 23, the upper panel 4 and the top panel 3 can be immediately combined and fixed. In this case, as long as the male and female screws 7, 17 of the male and female connecting bodies 1, 2 are firmly locked, the locking operation under the upper panel 4 can be omitted, and a more efficient board can be performed. The connection of the pieces is combined with the operation.

314211.ptd Page 16 1221509 V. Description of the invention (11) The buckle of the present invention, which can realize the combination of two plates, can be pushed inwardly into the locking shaft portion 6 protruding below the upper panel 4. The elastic locking claws 11 are released, and the coupling with the edge portions of the locking through holes 23 is released, the male connector 1 is simply pulled out, and the top plate 3 is detached from the upper panel 4. The push-in operation of the elastic locking claw 11 can also be performed simply by grasping it with a finger, but it can also be performed with a suitable tool. When the male connector 1 is twisted and separated from the female connector 2 after being withdrawn from the stopper through-holes 23, only the female connector 2 remains on the top plate, which is advantageous when disposal is required. In addition, as described in detail in the foregoing description, since the male fastener 1 can be easily removed from the upper panel 4 of the buckle of the present invention, the removal operation of the top plate can be easily performed, and even if the upper panel is a metal plate, Since plastic fasteners are left here, the sorting operation at the time of disposal becomes extremely easy. As mentioned above, the fastener of the present invention has been described based on the embodiment shown in the drawings. However, if the female connector 2 constituting a part of the fastener is not made as an independent body, it is formed by using plastic materials as described above. In the case of the top plate 3 of one plate, a cylindrical body may be provided at a portion corresponding to the fixed portion 21 to form a fitting recess 16 and a female screw 1 may be directly formed on the inner peripheral surface by thread processing. 7. In this case, an additional forming step may be omitted. When the female connecting body 2 is formed by this method, since it is integrated with the top plate 3 and the material is the same, it not only omits the assembly operation, but also has the advantage of no need for the sorting operation at the time of disposal. In addition, when forming this female coupling body 2, it is formed in the fitting recessed part 16

314211.ptd Page 17 1221509 V. Description of the invention (12) Although the forming of the female screw 17 on the inner peripheral surface is troublesome, as long as the connecting body 2 is formed in a state of being divided into two at the central portion, and it is installed When the fixed portion 21 is made to face each other to form a cap shape and fixed, the difficulty in forming can be easily solved. Furthermore, in order to facilitate the reduction in diameter of the insertion portion 5, although four slits 8 are provided and divided into four parts, the slits may be two, three, or more. This slit mainly assists the deflection of the inserting portion 5 and can maintain a predetermined outer diameter in the normal state. Therefore, it is not necessary to limit the number, width, or cut-in depth. The number of the elastic locking claws 11 provided in the locking shaft portion 6 is two in the embodiment, but it may be one or three. However, if a large number of elastic locking claws are provided to release the locked state, the operation becomes complicated, so it is of course best to select it appropriately. In addition, the retaining portions 15 for twisting the male coupling body 1 are also the same as above, except that a cross-shaped shape is assumed by using a screwdriver, and the formation of a letter (-) shape does not hinder the present invention. Implementation. Of course, in addition to these, an uneven portion may be formed on the outer peripheral surface of the tip portion as a frictional resistance portion during a twisting operation. When the fastener of the present invention used and constructed as described above is used, for example, when the top plate is fixed to an upper panel such as a library, when the plate and the plate are connected in a face-to-face state, the female connector is set on one side first. Plate, and here the female connector assembles the two bodies through the insertion portion of the male connector, and then the locking shaft portion of the male connector passes through the other plate and is pushed into the stopper. Holes, so that the two boards can be connected immediately, or

314211.ptd Page 18 1221509 V. Description of the invention The above female stop shaft is buckled to the male body, the female screw is easy to connect, and the back side buckle claw is easily disassembled, as long as the twist has a (13) shape connection Into the front, borrow the wire, borrow the advantages. This buckle is used to push the male plate and other discarded places such as the top plate on one side of the plate. The buckle is through the through hole, and then the inserting part is fitted. This can be simply connected. At the same time, the buckle of the male shape is attached to In addition, α 士 α, mountain square plate, and then 使 合 凹 but w #, and lock the two plates, so there is a side body that can be accommodated due to the buckle, which makes it reasonable. In addition, it is easy to carry out the disposal of the discards, and the state of the female screws is mutually stable, and it is easy to solve the problem. On the one hand, the invention does not need to deal with the top plate. Because of this. Moreover, the problem of insufficient hair is present, and the locking operation is firmly combined. By having a skewed party to make this, it is necessary to make it stay more than to retreat in a through hole, such as a plate, but also The buckle that can be easily processed in the subsequent order is formed by a plate on the board. The buckle used above is used to release the buckle and the buckle is removed from the female. It can be simply surrounded by the other parts of the homogeneous metal screw panel. In the state, the case of the excellent plastic material and plastic product connecting cap divided by the through-hole drawing connecting body clearly shows that the buckle has superior advantages because it is male and can be connected by the male shape. A plurality of fasteners are engaged, and the advantages of each part are adjusted. In the case of two plates, when the twisting operation of the joint between the plate and the female body is pushed into a single push, and the two plates can be pushed, the elasticity of the locking plate surface of one of the fasteners can be accommodated. The disassembly can be straightened because of the shaper, and the joints of the work pieces can be joined together, and the two obtained plates can be distorted. May:
