DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(12) Below is a further description of the present utility patent based on the drawings.

(13) This embodiment only shows an explanation of the present utility patent and is not a limitation to the present utility patent. Technicians in the art can make modifications to this embodiment as needed without making any creative contributions after reading this specification, which are always protected by the patent law as long as they are within the scope of the claims of the present utility patent.

(14) This embodiment relates to an ejection toy, as shown in FIGS. 1-3 and 5, which comprises a casing 100, an elastic energy-storage & launch mechanism 200, a bullet 300 and a string 400. The elastic energy-storage & launch mechanism 200 is set on the casing 100 and the bullet 300 is fit to the elastic energy-storage & launch mechanism 200. The elastic energy-storage & launch mechanism 200 is used for launching the bullet 300, and the casing 100 is provided with a container a for string 400 retracting. In this embodiment, the opening of container a is detachably provided with a protective cover 101 for the user to arrange or replace the string 400 retracted in the container a. As shown in FIG. 3-6, the ejection toy also includes: a string retracting mechanism 500, an ejection locking mechanism 600 and a driving component 700; The string retracting mechanism 500 includes a movably set string retracting wheel 501 in the container a and a friction wheel 502, wherein the friction wheel 502 is opposite to the string retracting wheel 501; The two ends of the string 400 are respectively connected to the container a and bullet 300, and the string is held between the string retracting wheel 501 and friction wheel 502.

(15) Optionally, one end of the string 400 is fixed in the container a through a screw, and the other end is tied and fixed to one end of the bullet 300. In other embodiments, the container a is provided with a fixing column, and both ends of the string 400 are tied to the fixing column and one end of the bullet 300, respectively. The driving component 700 is set in the casing 100 for driving the string retracting wheel 501. The ejection locking mechanism 600 is set on the casing 100 for locking and fixing the bullet 300 on the elastic energy-storage & launch mechanism 200 or driving the string retracting wheel 501 and friction wheel 502 to release the string 400 while unlocking the bullet 300. In some embodiments, the bullet 300 is detachably provided with a bullet-loading part at the end away from the locking track d. The bullet-loading part can be adsorbed on the object being shot due to its adsorption. The bullet-loading part and bullet 300 can be connected through magnetic suction, thread or snap-fit.

(16) It should be noted that when launching the bullet 300, the user can use the ejection locking mechanism 600 to unlock the bullet 300 while driving the string retracting wheel 501 and friction wheel 502 to release the string 400, making the elastic energy-storage & launch mechanism 200 launch the bullet 300 without entangling of the string 400 around a reel. The string 400 can be directly retracted in the container a, reducing the resistance caused by pulling the reel during launching, making smoother bullet 300 launching, avoiding knotting or seizing of the string 400 caused by part of the string 400 falling off the reel and being jammed when the reel rotates continuously due to inertia under an incomplete bullet 300 launching, and achieving smoother bullet 300 launching and/or string 400 retracting. When the ejection toy is subject to string seizing, the string can be directly pulled out and then retracted through the string retracting mechanism. It is not necessary to disassemble the ejection toy and then arrange and retract the seized string, facilitating the maintenance of the ejection toy. The ejection locking mechanism 600 can drive the string retracting wheel 501 and friction wheel 502 to approach each other to hold the string 400 under its own restoring force. The driving component 700 drives the string retracting wheel 501, and at the same time, the string retracting wheel 501 drives the friction wheel 502 under a friction force, making the string 400 held between the string retracting wheel 501 and friction wheel 502 move towards the container a under the friction force, and thus achieving string retracting.

The motor 701 is set in the casing 100. The transmission component is fixed on the output shaft of the motor 701 and rotatably fit on the rocker arm 614 through the second rotating shaft 601.

(26) Preferably, the transmission component includes: a worm 702 and a gear 703. The worm 702 is fixed on the output shaft of the motor 701. The gear 703 is set within the rocker arm 614 that can mesh with or separate from the worm 702 driven by the rocker arm 614. The string retracting wheel 501 rotates synchronously with the gear 703 through the second rotating shaft 601. In other embodiments, the transmission component includes two bevel gears 703 that can mesh with each other. The two bevel gears 703 are respectively fixed to the output shaft of the motor 701 and the second rotating shaft 601 connected to the string retracting wheel 501.

(27) It should be noted that when the bullet 300 is sequentially inserted into the launch hole b, launch tube c and locking track d, and the sliding buckle 612 snap-fits to the snap-fit slot e, the bullet 300 will compress the first elastic member 202. When the bullet 300 is ready for launch, the user can press the trigger 602, at this time, the bulge part 609 of the trigger 602 will push the linkage 603 to slide in the sliding slot k during rotation, making the linkage 603 move between the two rocker arms 614. The fourth sloping surface at one end of a rocker arm 614 contacts with the fifth sloping surface on the linkage 603, so the linkage 603 can expand the angle between the two rocker arms 614 during moving. The rocker arms 614 can help to separate the gear 703 from the worm 702 during rotation while driving the string retracting wheel 501 and friction wheel 502 to release the string 400; At the same time, the sliding of the linkage 603 makes the propping part 605 of the linkage 603 insert into the butt-joint slot i along the first sloping surface, thereby driving the sliding buckle 612 to move downwards, separating the sliding buckle 612 from the snap-fit slot e of the bullet 300, unlocking the bullet 300 and allowing launching of the bullet 300 by the first elastic member 202. When the user releases the trigger 602, the linkage 603 can reset under the restoring force of the second elastic member 604, the sliding buckle 612 can reset under the restoring force of the third elastic member 613, and the rocker arms 614 can reset under the restoring force of the fourth elastic member 615, making the string retracting wheel 501 and friction wheel 502 hold the string 400. When retracting the string and pressing the control switch 705 to control the motor 701, the motor shaft can drive the worm 702 as well as the gear 703 to rotate. The gear 703 drives the string retracting wheel 501 through the second rotating shaft 601, and the string retracting wheel 501 drives the friction wheel 502 through friction while making the string 400 be retracted into the container a.

(28) Preferably, in order to avoid entangling of the string 400 around the string retracting wheel 501 and/or friction wheel 502 during string retracting in the container a, as shown in FIG. 5, the container a is provided with separator parts 102. The separator parts 102 have openings connecting to the locking track (d); The separators are used to separate the string 400 in the container a from the string retracting wheel 501 and the string 400 in the container a from the friction wheel 502.
