Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 5 The utility model provides a technical solution: a compound bow and arrow bow opener, including a mounting frame 1, a threaded rod 2 is connected to a bearing on the mounting frame 1, an L-shaped telescopic frame 3 is connected to the left side of the mounting frame 1, a left T-shaped fulcrum 4 is fixed to the right side of the telescopic frame 3, a first support 5 is fixed to the upper end surface of the telescopic frame 3, a left clamping claw 6 is installed on the first support 5, a first fixing frame 7 is also connected to the telescopic frame 3, a left handle bracket 8 is fixed to the front end surface of the first fixing frame 7, a mounting bracket 9 is arranged on the right side of the front end surface of the mounting frame 1, a right T-shaped fulcrum 10 is fixed to the right end surface of the mounting bracket 9, a second support 11 is fixed to the upper end surface of the mounting bracket 9, a right clamping claw 12 is installed on the second support 11, a second fixing frame 13 is fixed to the mounting bracket 9 by bolts, and a capstan 14 is fixed to the front end of the second fixing frame 13.

[0021] The lower end surface of the mounting frame 1 is symmetrically fixed with a support leg 101, and the front end surface of the mounting frame 1 is fixed with a connecting piece 102, and the connecting piece 102 is connected and fixed to the mounting bracket 9 by bolts; the telescopic frame 3 and the threaded rod 2 are threadedly connected, and the telescopic frame 3 and the mounting frame 1 are slidingly connected; the position of the left T-shaped fulcrum 4 corresponds to the position of the right T-shaped fulcrum 10, and the left T-shaped fulcrum 4 is located directly below the left claw 6, and the right T-shaped fulcrum 10 is located directly below the right claw 12; the position of the left claw 6 corresponds to the position of the right claw 12, and the ends of the left claw 6 and the right claw 12 are both sleeved and fixed with rubber sleeves; the first fixing frame 7 and the telescopic frame 3 are nested, and the first fixing frame 7 and the telescopic frame 3 are locked by bolts;

[0022] When using the compound bow opener, Figure 1-Figure 5As shown, first, the support foot 101 is fixed to the desktop by bolts to ensure the stability of the device installation. When the compound bow needs to be opened, the distance between the left clamping claw 6 and the right clamping claw 12 is adjusted according to the size of the compound bow. At this time, by rotating the threaded rod 2 and cooperating with the threaded connection between the threaded rod 2 and the telescopic frame 3, the telescopic frame 3 can be slid in the mounting frame 1, thereby adjusting the total length of the mounting frame 1 and the telescopic frame 3, thereby achieving the distance adjustment effect between the left clamping claw 6 and the right clamping claw 12. After the adjustment is completed, the left clamping claw 6 and the right clamping claw 12 are engaged and fixed with the bow body to achieve the installation of the compound bow. At this time, the bow body can be lifted and protected by the action of the left T-shaped fulcrum 4 and the right T-shaped fulcrum 10 to prevent the bow body from sliding down and being damaged during the opening process. After the installation is completed, the threaded rod 2 is rotated again to reduce the total length of the mounting frame 1 and the telescopic frame 3. At this time, the left clamping claw 6 and the right clamping claw 12 provide pressure on the bow body, thereby achieving the opening effect.

[0023] The mounting bracket 9 is vertically distributed with the mounting frame 1, and the front end surface of the mounting bracket 9 is flush with the front end surface of the telescopic frame 3; the winch 14 is connected with a pull rope 1401, and the winch 14 is also connected with a rocker arm 1402;

[0024] When testing the draw of a compound bow, Figure 1-Figure 5 As shown, at this time, it is only necessary to assemble the bow body and the left handle bracket 8 to achieve the positioning of the compound bow, and then the draw rope 1401 and the compound bow are linked through the lock, and the rocker arm 1402 drives the winch 14 to reel in the draw rope 1401. The draw rope 1401 can provide tension to the bowstring. At this time, since the bow body and the left handle bracket 8 are coordinated to achieve positioning, the bow pulling detection function can be realized. This is the working principle of the compound bow and arrow bow opener.
