Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to Fig. 1-5, in the utility model embodiment, a kind of fast quick-mounting rubber band and the rotatable bullet of bow
Bow, including catapult handle 1, catapult shelf 2 and catapult bow arm 5, the top of catapult handle 1 is fixed by screw 3 and catapult shelf 2
Connection, is provided with fixed seat 4 in the side of catapult shelf 2, clutch shaft bearing 10 is provided with the top of fixed seat 4, in fixed seat 4
Bottom second bearing 11 is installed, steel loop 8 is provided between clutch shaft bearing 10 and second bearing 11, steel loop 8 withstands first
The inwall of bearing 10 and second bearing 11, it can so prevent that clutch shaft bearing 10 and the center stressed of second bearing 11 damage by pressure during locking
Clutch shaft bearing 10 and second bearing 11, catapult bow arm 5 is installed at the top of fixed seat 4, be provided with the bottom of catapult bow arm 5
Bend cylinder 12 under arm, the tail end of cylinder 12 is provided with screw thread 7 in the case where bending arm, bends cylinder 12 under arm and runs through clutch shaft bearing 10, second
The centre bore of bearing 11 and steel loop 8, catapult bow arm 5 are fixedly connected with fixed seat 4 by screw thread 7 with nut, can so make bullet
Bow bow arm 5 is in the 2 cofree rotation of catapult shelf, and so as to realize the rotation of bow, the top of catapult bow arm 5 is provided with dovetail
Groove 13, strong magnetic 9 is provided with the inside of dovetail groove 13, and dovetail groove 13 is fixedly connected with catapult rubber band 6, catapult skin by strong magnetic 9
Muscle 6 is tightly pushed down in the dovetail groove 13 on catapult bow arm 5 by the strong magnetic 9 of two panels, sets dovetail groove 13 and strong magnetic 9 to fix bullet
Bend rubber band 6, make catapult rubber band 6 installation fastening and it is difficult for drop-off, when changing catapult rubber band 6, as long as bullet can just be made by releasing strong magnetic 9
