5 is a view showing a stress acting on the handle 100 when an external force acts on the rim 200 of Fig.

As shown in the figure, when an external force acts on the bows by the user in a state where the rim 200 and the handle 100 are engaged, the rim 200 is bent and the rim 200 The greatest stress is applied to the fixed block 400.

More specifically, when an external force acts on the rim 200 in the P1 direction, the rim 200 is bent without being detached because it is fixed by the latching member 114 located at the point P3.

At this time, when the rim 200 bends, the receiving space 110 located at the end of the handle 100 supports a part of the rear surface of the rim 200. The receiving space 110 of the handle 100 located on the rear surface of the rim 200 is pressurized by an external force acting on the rim 200.

Here, the pressure applied to the handle 100 gradually increases toward the direction P1 along the longitudinal direction about the point P3. Therefore, as shown in the drawing, the greatest pressure is generated at the point P2 and the pressure is applied to the handle 100 through the pressure.

As shown in FIG. 5, when an external force acts on the point A 1 and a point of action of the point A 3 is fixed, the supporting point of the point A 2 is pressurized and the size thereof becomes larger as the point A 2 moves away from the point A 3 .

Since the generally used bows are surface treated with carbon coating, the coating can be peeled off by external pressure or wear.

As such, if the handle 100 is continuously pressurized through continuous use of the bow, the handle 100 may be damaged, and if the handle 100 is damaged, the overall accuracy of the bow may deteriorate.

Thus, the handle 100 according to the present invention is configured such that the rim fixing block 400 is located at the point P2 where the greatest pressure is applied, as shown in the figure. The rim fixing block 400 can directly prevent the pressure caused by the bending of the rim 200 from being transmitted to the handle 100 without damaging the handle 100. [

At this time, the rim fixing block 400 is not subjected to surface treatment with carbon coating so as not to be damaged by the rim 200, and a separate member other than the rim 200 and the handle 100 is used. The rim fixing block 400 is made of an aluminum material and anodized to improve the corrosion resistance and the wear resistance.

Here, not only the material but also the shape of the rim fixing block 400 is important. In order to prevent the rim fixing block 400 from damaging the handle 100 from the pressure by the rim 200, the rim fixing block 400 is inserted into the receiving space 110 Should be formed to have a width corresponding to the width of the rim 200 at the outer end portion along the longitudinal direction.
