According to the above description, referring to fig. 4 to 8, when the user performs the shooting operation of the bow and arrow, the initial step is to pull the bow string to the shooting position, so the pivoting of the pull handle set 2 drives the hair-catching device on the gun body 11 to move towards the bow string direction and hook the bow string, after that, the user pivots the pull handle set 2 again to reset, the hair-catching device will reset along the original position, so the bow string can be pulled and tightened towards the rear, then the bow and arrow can be erected on the gun body 11 to prepare for shooting, however, in the resetting process of the pull handle set 2, the bow string is set to be very tight, so the user with small strength must use very large strength to pull the bow string, so the invention uses the setting of the retractor set 4 to provide the user with easy operation, when the user swings the handle set 2 out toward the pistol grip 12 to form a controllable state, and during the swinging of the handle set 2, due to the arrangement of the teeth of the limiting fluted disc 44, the pulling of the handle set 2 drives the elastic rolling element 41 to stretch and extend elastically, and the elastic rolling element 41 and the limiting fluted disc 44 both use the support rod 42 as the axis, so that the elastic rolling element 41 drives the limiting fluted disc 44 to rotate together by the support rod 42, and the rotation of the limiting fluted disc 44 causes the stop element 43 to form a tooth jumping motion relative to the limiting fluted disc 44, thereby allowing the user to swing the handle set 2 quickly to pull the bowstring; when the user needs to pivot the pull handle set 2 to return to the original position and engage with the pistol grip 12, the user does not need to laboriously pivot the pull handle set 2 to return to the original position by the elastic rolling force of the elastic rolling member 41 in cooperation with the user's pulling force, which is easy and labor-saving, and the user must pull the stop member 43 during the pulling process to form a controllable state between the stop member 43 and the limit fluted disc 44, so as to pivot the pull handle set 2, and the user can stably perform the subsequent shooting operation by keeping the physical strength through the pulling of the elastic rolling member 41 and the force applied by the user, unlike the prior art which needs to consume a great force to pull the bowstring, resulting in the subsequent shooting operation, please refer to fig. 6 to 9, and refer to fig. 2 as an auxiliary description.

In addition, in order to prevent the user from unexpected accidents (such as the user has no strength, forgets to open the safety device, etc.) during the pivoting and resetting operation of the handle set 2, the arrangement of the stop member 43 is utilized to allow the user to suspend the operation at any time during the operation, the sliding opening 21 is communicated with the interior of the handle set 2, the stop member 43 comprises a cut-control portion 431 and a pressing portion 432, the pressing portion 432 is connected to one side of the cut-control portion 431 and is located inside the handle set 2, the cut-control portion 431 partially penetrates through the sliding opening 21 and is located outside the handle set 2, the stop member 43 pivots and is clamped against the limit gear plate 44 by the pressing portion 432 to limit the rotation to form a limited state, as shown in fig. 9 briefly, and assisted by fig. 2, when the user prepares to operate and pull the string in the pivoting and swinging of the handle set 2, after confirming that the string has been hooked and abutted, the user can touch the cut-control portion 431 with a finger and apply a force to slide, so that the stop member 43 pivots along the opening direction of the sliding opening 21, the swing of the cut-control portion 431 drives the pressing portion 432 to move together (as shown by a solid arrow in fig. 7, i.e. to the swing direction of the stop member 43), the displacement of the pressing portion 432 can be blocked in the direction that the tail end faces the limit fluted disc 44, so that the elastic rolling member 41 can be indirectly limited, and the elastic rolling member 41 is not rolled up by itself, thereby allowing the user to perform other things, inspection, rest and the like, or when the user suddenly fails in the process of pivoting and resetting the pull handle set 2, the stop member 43 can be slid to interrupt the pivoting and resetting operation of the pull handle set 2, and the user can continue to switch the stop member 43 to form the release state after a short rest to pivot and reset the pull handle set 2, therefore, better safety protection is provided, and the problems of clamping injury, bruise and the like of a user caused by the resetting of the pull handle group 2 are prevented.

Continuing the above description, in order to make the user stop the pivotal swing of the handle assembly 2 in the midway and keep the safety without being collided and injured by the pivotal swing of the handle assembly 2, the stop member 43 must be able to reliably abut against the limit toothed disc 44, so a pin 22 and a spring member 23 are further provided in the handle assembly 2, the pin 22 is adjacent to the retractable retractor assembly 4, the spring member 23 is assembled with the other end of the pin 22 by one end thereof to abut against one end of the limit toothed disc 44 by the stop member 43, when the pivotal swing of the stop member 43 is released from the abutment with the limit toothed disc 44, the stop member 43 pulls the elastic tension of the spring member 23 to generate elastic force, and after the external force applied to the pivotal swing of the stop member 43 disappears, the spring member 23 drives the stop member 43 to pivotally swing to reset and abut against the limit toothed disc 44 by the elastic force, so when the stop member 43 is not pulled by the pivotal swing, one end of the stop member 43 is normally engaged with the teeth of the limiting gear disc 44, so as to indirectly limit the elastic rolling of the elastic rolling member 41, and further effectively control the pivotal swing of the pull handle set 2, please refer to fig. 7, and take fig. 2 as an assistant. In addition, in order to make the pulling handle set 2 can reliably drive the elastic rolling member 41 to stretch and extend, the assembly buckle portion 14 of the gun body 1 of the present invention is mainly implemented by opening the end of the gun handle 12, so a bolt 122 is further disposed in the gun handle 12 corresponding to the assembly of the elastic rolling member 41, one end of the elastic rolling member 41 is fixed to the bolt 122, and the pivoting of the pulling handle set 2 relative to the gun body 1 drives the elastic rolling member 41 to stretch, please refer to fig. 2 and 5.

Finally, after the user controls the pull handle set 2 to reset, in order to prevent the pull handle set 2 from automatically separating from the combination with the gun handle 12 and affecting the tension of the bowstring and the shooting of the bow and arrow, the fastener set 3 can prevent the pull handle set 2 from automatically separating, and the fastener set 3 further comprises a hook fastener 31 and a spring 32, one end of the hook fastener 31 is pivotally assembled in the pull handle set 2, the spring 32 is sleeved at the other end of the pull handle set 2 and is propped against a clamping convex block 311 of the hook fastener 31, the hook fastener 31 is pivotally assembled at the opposite end of the pull handle set 2 and is provided with a hook 312, in addition, the gun handle 12 is provided with a positioning column 123, the hook fastener 31 is pivoted towards the gun handle 12 and is propped against the positioning column 123 by the hook 312, thereby the pull handle set 2 can be reliably hooked with the gun handle 12 after being reset, and the separation of the pull handle set 2 can be prevented from affecting the shooting, please refer to fig. 2 and fig. 3.

To summarize, the present invention mainly provides that the user can operate the pull handle set 2 in a more relaxed and labor-saving manner during the resetting process, so that the arrangement of the retractable retractor set 4 is utilized, the elastic winding force of the elastic retractor 41 is matched with the force of the user to pull the pull handle set 2 to reset, so that the pull handle set 2 can be reset quickly and easily, the arm ache is prevented from affecting the subsequent shooting operation, the pivoting of the stop member 43 can provide the user with a short rest in operation, the present invention is very suitable for the user with less strength, compared with the existing bow operation, the user needs to pull the bow with great force due to the tight arrangement of the bow string, and the user with less strength will certainly waste more force, resulting in the subsequent weakness of the subsequent shooting operation, the invention can not stably shoot to influence the precision, thereby the invention really improves the defects and the problems of the prior bow, and obviously has certain progress and practicability.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications, equivalent variations and modifications made to the above embodiment according to the technical spirit of the present invention still fall within the scope of the technical solution of the present invention.
