いので、組立作業の不便を招く。[0005] A system in which the two rods 11 are connected to each other by the two sleeve nuts 12 and the connecting screw 13 as in the conventional joint handle 1 described above may be used. Since the structure is completely the same, connecting screw 1
3 When both ends are screwed into the screw holes 121 of the sleeve nuts 12, the screwing force between the sleeve nuts 12 and the connection screw 13 is equal, so that it is necessary to change the use of this type of conventional joint pattern 1. Alternatively, for the purpose of reducing the storage space, both rods 1
When the two rods 11 are relatively loosened and turned to disassemble and separate the sleeve nuts 1, the sleeve nuts 1 fitted in the respective openings 113 are removed.
Since the screwing forces of the screw 2 and the connecting screw 13 are equal, the connecting screw 13 can be fixed in one of the sleeve nuts 12. That is, under the condition that the screwing forces of the connecting screw 13 and the sleeve nuts 12 are equal, the two rods 1
It is not fixed which side the connecting screw 13 remains when disassembling and separating 1. If there is a possibility that the connecting screw 13 will be fixed to one of the two rods 11, then it may be fixed to the other. As is well known,
In order to facilitate the connection, it is desirable that one of the joint members at both ends of each connecting rod 11 be a male and the other a female couple.
As an example, when the two rods 11 are separated from each other, it is most preferable that the connecting screw 13 is left and fixed on the right rod 11.
If 3 'is attached and the connecting screw 13 is screwed to the right end of the left rod 11, it is inconvenient in terms of assembly, and the right connecting screw 13 of the left rod 11 must be removed with a tool. Must be fixed to the left end of the right rod 11, which causes inconvenient assembly work.

するのである。The connecting screw 6 is used to abut the first and second sleeve nuts 4 and 5. A screw 61 is provided on the outer peripheral surface along the axis thereof, and hexagonal fixing holes 62 are provided on both end surfaces thereof. It is recessed. Then, as shown in FIGS.
When assembling the present embodiment, the first and second sleeve nuts 4 and 5 are respectively fitted into the opposing second openings 312 of both rods 3 so that the edges of the second openings 312 are respectively set. The first and second sleeve nuts 4 and 5 are tightened and fixed by caulking and pressing in the axial direction of the rod 3, and then one end of the connection screw 6 is connected to the first screw hole 44 of the first sleeve nut 4. Then, the second screw hole 53 is screwed into the other end of the connection screw 6 so that the second sleeve nut 5 and the first sleeve nut 4 are in close contact with each other, and thus connected. Both ends of the screw 6 are firmly screwed into the first and second screw holes 44 and 53 to connect the two rods 3 in series. In this screwing operation, the first and second sleeves are connected. The portions where the nuts 4 and 5 are opposed to each other are a spherical projection 43 and a spherical concave portion 54, and the degree of circularity of the spherical concave portion 54 is set to a sphere. Since the degree of arc of the convex portion 43 is slightly different from that of the convex portion 43, the flatness of the two rods 3 after serial connection can be ensured by the accurate fitting position between the spherical convex portion 43 and the spherical concave portion 54. At the same time, the spherical projection 43 having the split groove 431 formed by the compression of the spherical recess 54 is inserted into the first screw hole 4.
By elastically contracting in four directions, the connecting screw 6 can be tightened and clamped. That is, under the state where the first and second sleeve nuts 4 and 5 are screwed to the same connection screw 6,
The first sleeve nut 4 having the spherical projection 43 provides a fastening force in addition to the normal screwing force for the connecting screw 6, while the second sleeve nut 5 having the spherical recess 54 is provided. Provides only normal screwing forces to the connecting screw 6.

The second sleeve nut 5 is first rotated and separated by the difference in the binding force between the two ends because the other end is in a general screwing mode. That is, when the two rods 3 of this embodiment are separated and disassembled, the connecting screw 6
And the second sleeve nut 5 is detached from the connection screw 6. In other words, one end of each of the separated and disassembled rods 3 has the connection screw 6, and the other end has the other end. Since there is no connecting screw 6 and one end is male and the other end is female, the joint pattern 2 of the tool of the present invention can be more conveniently connected in series and reassembled. Of course, the connecting screw 6 may be directly fixed at the same time when the first sleeve nut 4 is molded from a plastic material.

うことができる。According to the present invention having the above-described structure, the two sleeve nuts are brought into contact with each other by the guide effect caused by the shapes of the spherical projections and the spherical recesses of the end faces of the two sleeve nuts which face each other. The coupling mode becomes more accurate, the flatness of the rods connected in series can be ensured, and the sleeve nut having the spherical projection applies a clamping force in addition to the screwing force to the connecting screw. Therefore, when the two rods connected in series are relatively loosened and rotated, the connecting screw remains fixed on the end face of the sleeve nut having the spherical projection, so that the next assembling operation of the serial connection is more conveniently performed. be able to.
