The technical scheme adopted by the invention for solving the technical problems is as follows: the tightening type leather bag slingshot is characterized in that a handle is connected to the tightening hoop, a long groove is formed in the middle of the handle, the long groove is along the length direction of the handle, one end of the long groove cuts the annular structure of the tightening hoop, and the length of the other end of the long groove is smaller than that of the handle; the open end of the leather bag is sleeved on the outer diameter of the fixing ring, and then the fastening ring is sleeved on the outer diameter of the fixing ring wrapped with the leather bag. The function of the tightening hoop is that firstly, the leather bag is pressed on the outer diameter of the fixing ring, and secondly, a handle is arranged on the outer diameter of the fixing ring. A through hole is arranged below the joint of the tightening ring and the handle, the through hole is intersected with the long groove, a nut half hole is arranged at one end of the through hole, a nut is placed in the nut half hole, a screw rod is inserted from the other end of the through hole, and the screw rod is screwed into the nut. And the screw rod is screwed down, and the tightening rings on the two sides of the long groove are tightened inwards by the screw rod, so that the diameter of the tightening ring is reduced, and the leather bag is tightly pressed on the outer diameter of the fixing ring. The leather bag is tightly pressed and fixed by the tightening hoop, and the handle is also installed and fixed below the fixing ring. The end face of the fixing ring is provided with a small boss, and the diameter of the small boss is larger than the inner diameter of the tightening ring. The small boss plays a safety role, and prevents the fixing ring from being pulled off and bounced to the hand of a person when the leather bag is pulled backwards in case the screw is not screwed down. Besides the method of tightening the tightening ring by using the screw, there are other ways to tighten the tightening ring, for example, the tightening ring can be tightened by winding the rope for several turns at the upper end of the handle, namely, the position where the nut is placed, and the gap between the long grooves is reduced, so that the leather bag is pressed between the fixing ring and the tightening ring.

The foam projectile is of a spherical structure and is made of foam materials. The foam material is either pu polyurethane rigid foam or polystyrene foam board; either rigid polyurethane foam, either eps foam, either pvc foam, or epe foam. The projectile is made of foam materials, firstly, the projectile speed can be reduced, and secondly, the foam projectile has the characteristic of light and soft and is relatively safe to use, so that the tight-hooped leather bag slingshot and the foam safety projectile can be used as relatively safe toys.

The method for assembling the hoop type leather bag slingshot comprises the steps of sleeving a leather bag on the outer diameter of a fixing ring, sleeving a tightening hoop on the outer diameter of the fixing ring wrapped with the leather bag, screwing a screw on the tightening hoop, and pressing a long groove by the screw, wherein the size of an opening of the long groove is reduced, so that the diameter of the tightening hoop is reduced, and the leather bag is pressed between the fixing ring and the tightening hoop.

The tightening type leather bag slingshot and the foam safety bullet have the advantages that the leather bag is tightly pressed on the fixing ring through the tightening ring with the handle, the installation of the handle and the pressing work of the leather bag are completed simultaneously, the installation is completed only by tightening one screw which is a standard component, the cost is low, the tool for screwing the screw can select an electric wrench, and the assembly efficiency is very high. The two main parts are fixed with no thread on the ring and the tightening ring, the die opening and taking efficiency is high, and the cost is relatively reduced. The foam pill has the characteristics of light and soft, and is relatively safe to use. The pressing structure of the leather bag has strong adaptability, and even a common balloon can be used as the leather bag of the toy slingshot. The tight-hooped leather bag slingshot is used in the same way as the traditional slingshot.
