[0056] Referring to Figures 1-14 The first elastic member 7 and the second elastic member 12 in the embodiment are both tension springs.

[0057] Referring to Example 2 The working principle of the rebound trigger device is as follows:

[0058] When in operation, the unlocker A and the rebounder B move in opposite directions, in the process, the unlocker A first contacts the vertical surface of the wedge-shaped block 402 on the first pusher 2, thereby driving the first pusher 2 to move inward; since the bottom of the first pusher 2 is connected with the second pusher 3 through the gear and rack transmission mechanism, in the process of the inward movement of the first pusher 2, the first rack 201 at the bottom of the first pusher 2 drives the gear 6 on the second pusher 3 to rotate, and since the second pusher 3 is also connected with the base 1 through the gear and rack transmission mechanism, the gear 6 on the second pusher 3 rotates and walks on the second rack 9, and at the same time, the second pusher 3 also moves inward synchronously with the first pusher 2; in the process, the hanging needle 5 on the first swing arm 4 in the first pusher 2 moves in the force storage section 101.

[0059] When the hanging needle 5 on the first swing arm 4 in the first pusher 2 moves from the force storage section 101 into the locking section 102, the first swing arm 4 rotates clockwise, so that the wedge-shaped block 402 on the first swing arm 4 enters the base 1, thereby enabling the unlocker A to continue to move inward beyond the wedge-shaped block 402; since the hanging needle 5 is located in the locking section 102, the locking assembly can lock the hanging needle 5.

[0060] When it is necessary to trigger the rebounding work of the rebounder B, it is necessary to promote the unlocker A to continue to move inward, so that the first driving part 1A of the unlocker A contacts the second swing arm 13, and the second driving part 2A of the unlocker A contacts the anti-push block 302 in the anti-push assembly; with the continuous inward movement of the unlocker A, the first driving part 1A in the unlocker A promotes the second swing arm 13 to rotate clockwise, and the second driving part 2A of the unlocker A compresses the anti-push block 302; in the process, the second swing arm 13 promotes the protector 14 to move inward against the elastic force of the third spring 15; with the clockwise rotation of the second swing arm 13, the lower end of the second swing arm 13 promotes the locking block 11 to move outward against the elastic force of the second elastic member 12, so that the release section 103 and the return section 104 are communicated, the hanging needle 5 enters the release section 103, and at the same time, under the elastic force of the first elastic member 7, the second pusher 3 moves outward and drives the first pusher 2 to move outward through the gear and rack transmission mechanism, so that the hanging needle 5 on the first swing arm 4 enters the return section 104 and enters the force storage section 101 again along the return section 104 and moves outward along the force storage section 101; in the process of the outward movement of the second pusher 3, the unlocker A is promoted to move outward.

[0061] When the needle 5 moves outward to the starting position of the force storage section 101, the unlocker A can continue to move outward under the action of inertia or external force, and when the first driving part 1A in the unlocker A contacts the inclined surface in the wedge-shaped block 402 on the first swing arm 4, the first driving part 1A in the unlocker A drives the wedge-shaped block 402 to move downward, so that the first driving part 1A in the rebounder B can continue to move outward after passing the wedge-shaped block 402.

[0062] When the unlocker A is separated from the second swing arm 13, the protector 14 moves outward under the elastic force of the third spring 15 to drive the second swing arm 13 to rotate counterclockwise, and the second swing arm 13 rotates counterclockwise to drive the locking block 11 to move inward, and the locking block 11 stops moving until it contacts the third limiting part 112 on the right side, and the locking block 11 blocks the entrance of the return section 104 again.

[0067] In the embodiment, the part connected with the dial block 171 in the unlocking arm 173 is an elastic part, and the elastic part constitutes the rotating connection structure.

[0069] Referring to Figures 1-14 The lock tongue 18 is provided with an inclined part and a vertical part.

[0070] Referring to ​ The working principle of the elastic force adjusting mechanism is as follows.

[0071] When it is needed to increase the elastic force of the first elastic member 7, the pushing block 171 is pushed inward (i.e. to the right), so that the pushing block 171 moves inward, when the elastic pushing piece 172 on the pushing block 171 contacts with the inclined part of the lock tongue 18, the inclined part of the lock tongue 18 will promote the elastic pushing piece 172 on the pushing block 171 to move upward, so that the elastic pushing piece 172 moves upward to pass through the lock tongue 18; when the pushing block 171 is pushed to the appropriate position, the pushing block 171 is released, so that the elastic pushing piece 172 in the pushing block 171 contacts with the vertical part of the corresponding lock tongue 18, so as to lock the pushing block 171, so as to realize the lengthening of the first elastic member 7, and further realize the increase of the elastic force of the first elastic member 7.

[0072] When it is needed to decrease the elastic force of the first elastic member 7, the unlocking arm 173 is pushed upward, so that the unlocking arm 173 lifts the elastic pushing piece 172 upward, so that the elastic pushing piece 172 is separated from the lock tongue 18, so that the pushing block 171 can move outward after passing through the lock tongue 18, so as to shorten the length of the first elastic member 7, so as to decrease the elastic force of the first elastic member 7.

[0073] The above is the preferred embodiment of the present application, but the embodiment of the present application is not limited by the above content, any change, modification, replacement, combination, simplification made without departing from the spirit and principle of the present application shall be equivalent replacement mode, and all shall be included in the protection scope of the present application.
