The lower handle and the lower handle are pivotally attached to each other in the straight rod portions by means of a shaft pin, and the upper handle and the lower handle are folded so as to overlap each other, and the straight rod portions are aligned with each other. The upper handle and the lower handle are configured so as to be rotatable between the upper handle and the lower handle so that the protrusions are provided on one side and the recesses are provided on the other side so that they can be inserted into and removed from each other. Are folded so that they overlap with each other and both straight rods are extended so as to be in a straight line with each other, one projection and the other recess of one of the overlapping surfaces of the two straight rods are fitted to each other. The upper and lower arms of the upper handle and the lower arm of the lower handle. It is provided with engaging portions with both ends.

This structure eliminates the need for the retaining ring that has been used in the past, and saves the trouble of changing the retaining ring when the bow is folded and when the bow is extended, and the straight rod portion of the lower handle and the straight rod of the upper handle are eliminated. By fitting the protrusion provided on either one of the parts and the recess provided on the other, the movement between the upper handle and the lower handle is stopped, and an inexpensive bow can be provided.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings (FIGS. 1 to 5).
It will be described based on FIG. In the drawings, the same reference numerals as those in the above-mentioned conventional example indicate the same members, and the detailed description thereof will be omitted and the different parts will be described in detail.

That is, in the embodiment of the present invention, the conventional retaining ring is eliminated, and a substantially hemispherical projection 18 is formed on the upper end of the straight rod portion 5 of the lower handle 4 above and below the shaft pin 7 that pivotally supports the upper handle 1 and the lower handle 4. A state in which the upper handle 1 and the lower handle 4 are folded and extended, in which the recesses 19 and 19 into which the protrusions 18 and 18 are fitted are provided at the lower end of the straight rod portion 2 of the upper handle 1 while integrally providing 18 At the protrusion 18,18
The movements of the upper handle 1 and the lower handle 4 can be stopped unless they are fitted into the recesses 19 and 19 and an external force is applied thereto.

More specifically, referring to the drawings, the shaft pin 7 is integrally projectingly provided from the pad member 8 to form a straight rod portion 5 of the lower handle 4.
Of the shaft pin 7 is inserted into a hole 21 formed at the lower end of the straight rod portion 2 of the upper handle 1 to penetrate the hole 20 formed at the upper end of the upper handle 1 and the lower handle. 4 are rotatably connected. Further, a hole 22 for inserting a shaft pin is formed in a mounting piece portion 11 of the hanging metal fitting 10 sandwiched between the upper end of the pad member 8 and the upper end of the straight rod portion 5. Is inserted. In this state, since the hanging metal fitting 10 rattles around the shaft pin 7, the pad material 8 has a hole formed in the mounting piece 11.
An almost hemispherical protrusion 24 that fits into the protrusion 23 is provided so as to prevent the hanging metal fitting 10 from moving. Reference numeral 25 is a concave portion formed in the straight rod portion 5 of the lower handle 4, and is adapted to be fitted into the hole 23 of the mounting piece portion 11 and to be fitted with the tip of a projection 24 protruding toward the straight rod portion 5 side. .

Further, in the embodiment of the present invention, the upper arm portion 3 of the conventional upper handle 1

In addition to projecting 26, a locking step portion 28 with a claw 27 is provided on the lower surface of the tip of the lower arm portion 6 of the lower handle 4. The claw 27 is provided so as to project downward at the rear end of the locking step portion 28. Further, the locking claw portion 26 is provided so that an L-shaped groove 29 is formed in a side surface shape when the tip of the upper arm portion 3 is viewed leftward.
The locking claw portion 26 at the tip of the upper arm portion 3 and the locking step portion 28 at the tip of the lower arm portion 6 configured as described above are used as the upper and lower locking portions of the lantern 14.
It suffices to set the bow on the lantern 14 by locking it to 30, 31 and at that time, the L-shaped groove of the upper locking portion 30 and the locking claw portion 26 of the lantern 14
By locking with 29, the lantern 14 and the bow are securely connected,
For example, in the case of the conventional locking step and the upper locking part of the lantern 14, there is a problem that the locking is easily released when some external force (shock) is applied. Since the bow and the lantern 14 are securely locked on the upper side, it is hard to come off.

Effects of the Invention As described above, according to the present invention, the snap ring that has been used conventionally is not necessary, and the work of changing the snap ring between when the bow is folded and when the bow is extended is eliminated, and the straight handle of the lower handle is eliminated.
