Referring to the situation shown in Figure 1, when opening the parachute, press the button 41, as shown in Figure 5, push the two side convex arms 71 of the umbrella opening control part 7 in the button 41, so that the parachute opening control part 7 is retreated, the opening The clamping sheet 72 of the umbrella control part 7 breaks away from the hole 242 of the sleeve pipe 241 at the lower end of the lower nest 24. At this moment, the tension spring 5 for opening the parachute pushes the outer tube 12 upwards to the top of the inner tube 11, and pulls up, Open each umbrella rib of the umbrella rib device 2 to form the umbrella opening state, as shown in Figure 1, at this time, the upper nest 21 moves up along the middle stick device 1, so that the drag cables tied to the lower nest 24 and the buckle device 84 85 is in a state of tension, and the buckle shoulder 843 of the buckle device 84 is stuck under the stopper 82 in the middle of the umbrella retracting control part 8, and each umbrella retracting elastic element 6 is opened by its upper and lower spring feet 62, 63 when the umbrella is opened. Compressed by the parietal bone 22 and the lower support bone 23 to store its elastic energy, so that the umbrella bone 2 can be folded at any time, and the lower nest 24 can be pushed down to prepare for the umbrella. When the elastic element 6 of the umbrella is to move down, the lower nest 24 must be Pull the dragline 85, and the buckle device 84 connected with the dragline 85 is locked and positioned, as shown in FIG.

During the operation process of opening the umbrella, when the button 41 is pressed, as shown in FIG. Press down and warp downward, so the action of opening the umbrella is sure, and the umbrella will not be closed for no reason by accidentally touching the umbrella control part 8 due to misoperation.

When wanting to close the umbrella, as shown in Figure 6, because the sleeve 241 at the lower end of the lower nest 24 moves upwards, the spring 311 on the lower side of the buffer sleeve 312 stretches and the buffer sleeve 312 moves up to be blocked by the umbrella opening control member 7. When the brake pad 42 on the button 41 returns to the horizontal shape, after pressing the button 41, as shown in Figure 7, the brake pad 42 moves forward so that the two sides of the long protruding arms 423 on both sides push up the two sides of the umbrella control part 8. The side protruding rod 81 drives the catch 82 of the umbrella control part 8 to move back and unbuckle, so that the buckle device 84 at the lower end of the drag cable 85 is no longer buckled, and the upper and lower spring feet 62, 63 of the umbrella elastic element 6 It can be stretched, push down the lower nest 24 and move down and make the umbrella rib device 2 fold the umbrella rib in the direction of the middle stick device 1 .

And when resetting the elastic energy of this parachute opening tension spring 5, as shown in Figure 2, 4, in pressing the handle 3, the sleeve pipe 241 of the lower nest 24 lower end of the outer tube 12 is slipped in the middle rod hole of the handle 3 31. Press the clamping piece 72 of the parachute opening control part 7 to make it retract, and because the spring 73 at the rear end of the parachute opening control part 7 supports the top, the clamping piece 72 is buckled with the hole 242 of the sleeve 241 at the lower end of the lower nest 24 , and at the same time slightly press the spring 311 on the lower side of the buffer sleeve 312 into a compressed state, and then make the convex body 3122 on the upper end of the buffer sleeve 312 press the brake pad 42 of the button 41 downward, so that the inner and outer tubes 11 of the middle rod device 1 , 12 are folded under the standby state, when the umbrella is retracted, the elastic energy of the tension spring 5 for opening the umbrella is compressed and accumulated, and the bottom end of the upper casing 14 connected to the inner block 13 at the upper end of the outer tube 12 also pushes down the buckle device 84 , so that the buckle head 841 enters the lower casing 15 at the lower end of the inner tube 11, and at the same time presses the baffle 82 of the umbrella retracting control part 8 to make it retract, and the spring 83 at the rear end of the umbrella retracting control part 8 props up the shoulder of the buckle head 843 sliding blocks are snapped and positioned at the lower end of the catch 82, so that the umbrella ribs are automatically folded next time.

In summary, the structural implementation of the utility model does have innovation and actual effect improvement.
