Description

Multifunctional slingshot

Technical Field

The invention relates to a slingshot, in particular to a multifunctional slingshot.

Background

The existing slingshot sighting telescope in the market is mostly a horizontal sighting telescope or a cross sighting telescope;

most of the horizontal sighting telescope is half sighting telescope, and the position of resilience of the rubber band is not blocked, so that the problem that the kinetic energy of the rubber band exceeds the defeat is solved.

When the cross sight is used for observing the target sight, the cross sight transversely and longitudinally supports the calibration of the target object which is easy to shield, so that whether the target object is accurately aligned with the sight of the cross sight cannot be found at the first time, and the accuracy of hitting the target object is reduced.

Application number 201811017777.3, publication date 2018.12.2 discloses an optic fibre is aimed at preforming catapult more, prop 20 and stretch bow area 121 including bow handle 11, bow, 11 tops of bow handle are equipped with locking connector 31, the bow props 20 and fixes and locates in the locking connector 31, the bow props 20 tops and is equipped with and penetrates frame 22, it is equipped with draw-in groove 8 to penetrate frame 22 top, it aims a little 13 to be equipped with optic fibre long-range point 101 and cross short distance in the draw-in groove 8, optic fibre long-range aim a little 101 with cross short distance is aimed a little 13 and is all fixed in through a movable bolt 33 on the frame 22, the both ends voltage-sharing of stretch bow area 121 is located optic fibre long-range aim a point 101 with between the inner wall behind draw-in groove 8, be equipped with warhead leather piece 80 on the stretch bow area 121 intermediate position. As a further improvement of the invention, the bottom of the bow handle 11 is provided with a hanging buckle 44. The bow handle 11 is provided with a plurality of holding holes 18.

In practical application, before the bullet head wrapping block 80 and the elastic bow band 121 are used, the tightness and firmness of the two ends of the bullet head wrapping block 80 and the elastic bow band 121 need to be checked, and the rebound of the elastic bow band 121 and the shooting operation safety of the bullet head wrapping block 80 in the shooting process are guaranteed. When in use, firstly, a user needs to hold the middle position of the bow handle 11 with the left hand and pull the bullet package block 80 wrapped with the shooter with the right hand; secondly, the user selects the cross short-range aiming point 13 or the optical fiber remote aiming point 101 according to the difference between the shot object and the shooting direction, or adjusts the positions of the cross short-range aiming point 13 and the optical fiber remote aiming point 101 by unscrewing the movable bolt 33, and screws the movable bolt 33 in place after the adjustment is finished, thereby aiming at the shot object more accurately; and finally, loosening the bullet packing block 80, and shooting the shot object to the shot object, namely the shooting target, so as to finish the shooting operation. During aiming, the 4 optical fiber remote aiming points 101 correspond to 4 different aiming distances and are distinguished by 4 color marks, namely red, yellow, blue and green, which respectively correspond to the aiming points with the distances of 10m, 20m, 30m and 40 m. If the aiming distance is within 10m, the cross short-range aiming point 13 can be selected for accurate aiming shooting. In addition, if the elastic bow 121 is worn after a long time use and needs to be replaced, the movable bolt 33 is only required to be unscrewed, the elastic bow 121 is drawn out from between the optical fiber remote aiming point 101 and the rear inner wall of the shooting frame 22 and replaced, after replacement, the elastic bow 121 is adjusted to a proper position, and the movable bolt 33 is tightened, so that the replacement operation is completed.
