[0032] Please see Figure 1-3 As shown, the ultra-short axis composite bow includes:

[0033] The bow body 1 has a bow handle 2 fixedly connected to its bottom surface;

[0034] Bow piece 6, which is fixed at the bottom of the bow handle 2;

[0035] A tension adjustment assembly is fixedly installed at the bottom end of the bow handle 2, and the tension adjustment assembly is fixedly connected to the bow piece 6;

[0036] A pulley system is rotatably connected to the bow body 1, and a secondary string 9 and a primary string 11 are provided on the pulley system;

[0037] A bow push indicator structure is fixedly installed in the bow handle 2;

[0038] The above technical solution adopts a single-sided bow design, which greatly reduces the volume and weight of the bow, making it particularly suitable for carrying and moving on the field, greatly reducing physical exertion. Furthermore, in order to solve the problem that ordinary beginners have difficulty fully straightening the bow when practicing archery, this application designs a bow-pushing indicator structure. By pushing the indicator structure, when the pressure on both sides of the bow handle 2 is the same when pushing the bow, it can provide corresponding indication, which facilitates the early training of beginners and avoids the problem of incorrect bow pushing caused by uneven pressure on both sides when pushing the bow.

[0039] The tension adjustment assembly includes a pressure plate seat 3, an adjustment screw 4, and a pressure rod 5. The adjustment screw 4 is rotatably connected to the pressure plate seat 3, and the adjustment screw 4 is threadedly connected to the bow handle 2.

[0040] The pressure rod 5 is fixedly installed at the bottom end of the bow handle 2. The pressure rod 5 is in contact with the bow piece 6. With this technical solution, when it is necessary to adjust the tension of the bow piece 6, the position of the pressure plate seat 3 can be adjusted by turning the adjusting screw 4. The angle of the bow piece 6 can be adjusted by adjusting the position of the pressure plate seat 3. In turn, the deformation of the bow piece 6 when the bow is fully drawn can be adjusted by adjusting the angle of the bow piece 6, thereby realizing the function of adjusting the tension.

[0041] The pulley system includes a main wheel 7, an eccentric wheel 8, a guide wheel 13, and a split-string wheel 10. There are two main wheels 7, which are connected by a fixed shaft. The fixed shaft is located at the bow body 1 and is rotatably connected to the bow body 1.

[0042] An eccentric wheel 8 is fixedly connected to the side wall of the main wheel 7. A secondary string 9 is connected to the eccentric wheel 8. The string splitting wheel 10 is located at one end of the bow piece 6 and is rotatably connected to the bow piece 6. The secondary string 9 and the string splitting wheel 10 are sleeved together.

[0043] Two guide wheels 13 are provided, and the two guide wheels 13 are respectively located on both sides of one end of the bow body 1 and are rotatably connected to the bow body 1.

[0044] Both main wheels 7 are connected to a main string 11. The main string 11 passes around two guide wheels 13. A D-ring nocking point 12 is fixedly set at the middle position of the main string 11. With this technical solution, when archery is to be performed, the athlete holds the bow handle 2 with their left hand, nocking the arrow at the D-ring nocking point 12. With their right hand, they hold the release device, hooking the D-ring nocking point 12. Using their back muscles, they move their right hand, which in turn moves the main string 11, thus drawing the bow. When drawing the bow, the main string 11... The movement of bow 11 causes the main wheel 7 to rotate, which in turn rotates the eccentric wheel 8. The rotation of the eccentric wheel 8 causes the secondary string 9 to bend, accumulating elastic potential energy. After the athlete draws the bow fully and completes the aiming motion, they continue to exert force with their right hand and control the release mechanism to release the bow. At the moment of release, the bow 6 quickly rebounds, causing the secondary string 9 to move. The secondary string 9 then rotates the eccentric wheel 8 and the main wheel 7, which in turn causes the main string 11 to rebound, converting the elastic potential energy into the kinetic energy of the arrow, thus launching the arrow. This technical solution achieves the arrow launching function. Furthermore, compared to ordinary compound bows, this application only has bow limbs and a wheel assembly in the lower half, greatly reducing the overall weight of the bow and making it easier to carry. It is particularly suitable for use in field competitions, facilitating frequent carrying and movement on the field, reducing physical exertion, and helping athletes conserve energy for archery, thereby improving performance.

[0045] The push-bow indicator structure includes an indicator 15, a fixed base 16, a conductive post 17, a rectangular protruding rod 18, a sliding rod 19, a conductive block 20, a wire A21, a wire B22, a wire C23, a mobile power supply 24, a wire D25, and a spring 26. The bow handle 2 has an internal cavity, and a push point patch 14 is fixedly installed on the side wall of the bow handle 2. Fixed bases 16 are fixedly connected to both sides of the internal cavity of the bow handle 2.

[0046] The fixed base 16 has a sliding groove inside. Conductive posts 17 are fixedly connected to both sides of the bottom of the sliding groove of the fixed base 16. A sliding rod 19 is slidably connected in the sliding groove of the fixed base 16. One end of the sliding rod 19 is fixedly connected to one end of a rectangular protruding rod 18. The other end of the rectangular protruding rod 18 penetrates the inner cavity side wall of the bow handle 2 and extends to the outside of the wall. A conductive block 20 is fixedly connected to the other end of the sliding rod 19. One end of a spring 26 is fixedly connected to one side of the sliding rod 19. The other end of the spring 26 is fixedly connected to the bottom wall of the sliding groove of the fixed base 16.

[0047] An indicator 15 is fixedly installed on the outer wall of the bow handle 2. One of the terminals of the indicator 15 is electrically connected to one of the conductive posts 17 via wire A21. The two conductive posts 17 on both sides are electrically connected via wire B22. The portable power supply 24 is fixedly installed in the inner cavity of the bow handle 2. One end of the portable power supply 24 is electrically connected to one of the conductive posts 17 via wire C23, and the other end of the portable power supply 24 is electrically connected to the indicator 15 via wire D25. With this technical solution, when the athlete holds this device for archery training, the left hand needs to push the bow handle 2, pressing the thenar eminence of the left hand against the push point patch 14 and pushing the bow. When the athlete's bow pushing position is relatively correct, the two sides of the thenar eminence will be pressed against the two rectangular protruding rods 18, applying pressure to make the rectangular protruding rods 18... The movement of the two rectangular protruding rods 18 allows the conductive block 20 to move to the position of the conductive post 17, making contact and energizing it. This creates a power circuit between the indicator 15 and the mobile power source 24, prompting the indicator 15 to alert the athlete to correct the push-bow position. When the push-bow is misaligned, the pressure on one side of the thenar eminence muscle is greater than the other, preventing one of the conductive blocks 20 from moving to the conductive post 17 due to the lower pressure. Consequently, the indicator 15 cannot issue an alert. The athlete can use the indicator 15 to determine if the push-bow hand position is correct, facilitating training and preventing the formation of bad habits due to prolonged incorrect training. This method is suitable for novice athletes.

[0048] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
