When the compound bow is pulled open, the rotation stopping part 4 of the pull distance module can be abutted against the auxiliary string at the tail sound stage of the bow opening. At this time, the plane part 22 of the second positioning part 2 abuts against the end part of the bow piece 6 to realize plane contact; because the plane contacts with 6 tops of arcualia piece, can prevent the unstability of contact between the cambered surface, its location effect of assisting location range is more stable.

In a second mounting mode, as shown in fig. 3, the second positioning portion 2 is mounted on one side of the wheel set 3, and compared with the first mounting mode, the second positioning portion 2 is rotated by 90 ° as shown in fig. 3. When the compound bow is pulled open, the rotation stopping part 4 of the pull distance module can be abutted against the auxiliary string at the tail sound stage of the bow opening. At this time, the arc part 21 of the second positioning part 2 abuts against the end part of the bow piece 6 to realize arc surface contact; the arc part 21 can be arranged on the rotation stopping part 4 of the pull distance module through the groove 23, can stride over the pull distance module to abut against the end part of the bow piece 6, and can prevent the situation that the end part of the bow piece stops contacting the end part of the bow piece 6 from occurring.

It should be understood that, in both mounting manners, the first positioning portion 1 is mounted on the other side of the wheel set 3 in the same manner, and is detachably connected with the wheel set 3 through a threaded hole.

The two installation modes have advantages, and a user can flexibly determine the installation mode of the stop point of the extension bow piece according to the type and the specific use condition of the composite bow and select the plane contact or the cambered surface contact with the top end of the bow piece.
