[0037] Embodiment 1

[0038] like Figures 1 to 11 As shown, this embodiment provides an integrated compound bow, including a single-use standard compound bow 1 and an operating mechanism 2; the single-use standard compound bow 1 is provided with a combined bow wheel group 14 at both ends, a long main chord 31 and a short main chord 32 are hung between the combined bow wheel group 14, the combined bow wheel group 14 includes an adjustable draw length secondary wheel 142 and two sets of main wheels 141, 143, the single-use standard compound bow 1 can be used in conjunction with the main wheel 141 to hang the long main chord 31, the adjustable draw length secondary wheel 142 is installed on the main wheel 141. The operating mechanism includes a shell 21, a release assembly 22 and a string-opening positioning assembly 23; one end of the shell is detachably mounted on the single-use standard compound bow 1, and along the long side direction of the shell 21, the release assembly 22 and the string-opening positioning assembly 23 are sequentially arranged on the shell, and the string-opening positioning assembly 23 is located at an end away from the single-use standard compound bow 1; when the compound bow is not equipped with an arrow, the release assembly 22 and the string-opening positioning assembly 23 maintain multiple locking to prevent the compound bow from being released in vain.

[0039] It should be noted here that the main wheel 141 and the main wheel 143 in the upper and lower combined bow wheel groups 14 correspond to each other one by one when used, and the main wheel 141 and the main wheel 143 in the same combined bow wheel group 14 are different in size, and the main wheel 141 is larger than the main wheel 143. When used in a single bow mode, the main wheel 141 is selected for use, and combined with the long main string 31, a longer draw distance can be achieved, and the adjustable draw length sub-wheel 142 is used to further adjust the draw distance required by the user. The two combined bow wheel groups 14 are also connected to two sub-strings 33.

[0040] like Figure 1 , 2 As shown in Figures 3 and 4, the bow body mechanism 1 includes a bow handle 11, a grip 12 and a bow piece 13; the bow handle 11 is located in the middle of the bow body mechanism 1; the grip 12 is detachably installed in the middle of the bow handle 11; the two ends of the bow handle 11 are respectively fixedly connected with the bow piece 13; the top of the bow piece 13 located above the bow handle 11 and the bottom of the other bow piece 13 are respectively installed with a combined bow wheel set 14.

[0041] It is worth mentioning here that by providing a detachable handle 12, the installation direction of the handle 12 can be changed, and the pulling distance can be fine-tuned without changing the pulling force.

[0042] like Figure 2 As shown, a connecting plate 121 is provided on the handle 12 , and a horizontal sighting instrument 122 is provided on the connecting plate 121 .

[0043] It is worth mentioning here that the user is assisted in judging whether the bow body mechanism is in a horizontal state, and then making corresponding position adjustments, thereby overcoming the problem that beginners cannot judge whether they can shoot arrows in a straight line, thereby improving the accuracy of arrows.

[0044] It should be noted that the housing 21 may also be equipped with a zoom lens to further assist in improving the accuracy of the arrow.

[0045] Embodiment 2

[0046] like Figures 1 to 11 As shown, the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0047] like Figure 1 , 11 As shown, the single-use standard compound bow 1 and the operating mechanism 2 can cooperate with the main wheel 143 to hang the short main string 32 to form a crossbow for use.

[0048] It should be noted that when the operating mechanism 2 is installed on the standard compound bow 1 that can be used as a crossbow, in order to be more ergonomic and avoid too long a draw length, the main wheel 143 is switched to hang a short main string 32 for use, and the adjustable draw length secondary wheel 142 is used to further adjust the draw length required by the user.

[0049] like Figure 1 , 9 As shown, the release assembly 22 is located at the front end or the middle end of the housing 21 .

[0050] It should be noted that it is preferred to arrange the release assembly 22 at the middle end of the housing 21, which is more in line with the choice of most people.

[0051] It is worth mentioning here that the release assembly 22 is disposed at the front end or the middle end of the housing 21, which is more ergonomic, allowing compound bow users of all ages to select a suitable compound bow according to their own needs and improve their archery experience.

[0052] like Figure 1 , 5 As shown in Figures 6 and 7, the release assembly 22 includes a fixing seat 221 fixed on the shell 21, and a trigger 222 is rotatably arranged on the fixing seat 221; a waist groove 223 is opened on the trigger 222, and a through shaft 224 is arranged on one side of the trigger, and a connecting shaft 225 is arranged on the through shaft 224, and the connecting shaft 225 slides in the waist groove 223; a long spacer block 226 is connected to one end of the through shaft 224, and a spring 227 is connected to the opposite side of the long spacer block 226 connected to the through shaft 224, and one end of the spring 227 is fixed to the shell 21; a trigger grip 228 is also arranged on the shell, and the trigger grip 228 is located on one side of the trigger 222.

[0053] It should be noted that when the trigger 222 is pulled, the trigger 222 drives the through-shaft 224 to move and then drives the long spacer block 226 to move. The spring 227 located on the opposite side maintains the pulling force to pull the through-shaft 224 back, so that the trigger is reset.

[0054] like Figure 4 As shown, a trigger guard 2221 is arranged outside the rotation track of the trigger 222 , and a safety release lock buckle 2222 is also rotatably arranged between the trigger 222 and the trigger guard 2221 .

[0055] It is worth mentioning here that a trigger guard 2221 is provided to protect the trigger 222, to prevent damage caused by foreign objects touching the trigger 222, and to avoid accidental triggering of the trigger 222 by the outside world; the safety release lock 2222 further provides limit protection for the trigger 222. When the safety release lock 2222 is locked on the trigger 222 and is not opened, the user cannot pull the trigger 222, thereby avoiding accidental triggering and improving safety.

[0056] like Figure 4 As shown, a finger buckle 2223 is provided at the lower end of the safety release lock buckle 2222.

[0057] It is worth mentioning that the finger buckle 2223 allows the user to easily use his / her fingers to activate the safety release buckle 2222 .

[0058] like Figure 1 , 5As shown in Figure 6, the open string positioning assembly 23 includes a connecting rod 231, one end of the connecting rod 231 is connected to the long spacer block 226, and the other end is connected to the short spacer block 232; a limit rod 233 is arranged through the short spacer block 232; a string hook 234 is rotatably arranged on the same side of the connecting rod 231 where the limit rod 233 is arranged; a safety lock 235 is intermittently adapted to engage the string hook 234.

[0059] It should be noted that when no arrow is loaded, the trigger 222 is pulled to cause the long spacer block 226 to drive the connecting rod 231 and the short spacer block 232 to move. Since the safety lock 235 is engaged and locked on the string hook 234, the string hook 234 cannot rotate to release the bowstring. When an arrow is loaded, the arrow squeezes the safety lock 235 to rotate, and the string hook 234 is no longer restricted from rotating. The trigger 222 is pulled to release the bowstring to shoot the arrow.

[0060] like Figure 5 As shown, an adjusting bolt 236 is also provided on the short spacer block 232 , and the adjusting bolt 236 can adjust the distance between the short spacer block 232 and the housing 21 .

[0061] like Figure 8 As shown, a roller 237 is rotatably provided on the string hook 234 at the contact area with the limiting rod 233 .

[0062] It is worth mentioning here that the roller 237 converts the contact between the string hook 234 and the limiting rod 233 from sliding friction to rolling friction, thereby reducing the friction between the components and increasing their service life.

[0063] Working steps

[0064] In the single bow mode, the user places the arrow on the long main string 31, pulls the long main string 31, and releases the string to complete the archery; in the crossbow mode, the user places the arrow on the short main string 32 and pulls it to the string hook 234, with the tail end of the arrow close to the hook groove of the string hook 234, and at the same time the string hook 234 hooks the main string 143, the arrow squeezes the safety lock 235 to rotate, so that the safety lock 235 no longer restricts the rotation of the string hook 234, opens the safety release lock 2222, and pulls the trigger 222 after aiming to complete the archery.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
