[0006] Preferably, the radius of the arc of the arc-shaped arrow head body is 20mm, the maximum diameter of the arc-shaped arrow head body is 5.32mm, and the diameter of the end of the arc-shaped arrow head body is 4.80mm.

[0007] Preferably, the length of the handle of the arrow head connecting handle is 31.50mm, and the diameter of the connecting handle of the arrow head connecting handle is 3.185mm.

[0008] Preferably, the glue groove is provided with two groups, and each group of glue grooves comprises three equidistant circular grooves.

[0009] Preferably, the total length of the arrow head connecting handle and the arc-shaped arrow head body is 44.50mm.

[0010] Preferably, the arrow head connecting handle and the arc-shaped arrow head body are an integral structure.

[0011] Compared with the prior art, the utility model has the beneficial effects that:

[0012] The utility model discloses an arrow connecting handle with multiple glue grooves, which can evenly distribute glue in the glue grooves when the arrow connecting handle is connected with the arrow shaft through glue, ensure the overall weight distribution more uniform, and improve the accuracy of archery.

[0013] The utility model discloses a smaller arc arrow main part, and removes the counterweight block at the rear end, which makes the whole center of gravity more forward, improves the FNC data of the arrow, and improves the archery performance. BRIEF DESCRIPTION OF DRAWINGS
