In some instances, well-known methods and structures are not described in detail to avoid unnecessarily obscuring these embodiments. Additionally, all embodiments can be used in combination with each other. Embodiment 1

[0036] A portable catapult toy includes a catapult part, an auxiliary buffer part, and a front cone head 20. The catapult part includes a hollow catapult outer shell 1 and a locking assembly. The locking assembly includes a cylindrical groove 2, a latch groove 3, and a locking spring 4. The latch groove 3 is movably arranged in the catapult outer shell 1. The locking spring 4 is arranged in the latch groove 3. The cylindrical groove 2 is movably arranged in the latch groove 3 and is in movable abutment with the locking spring 4. A plurality of locking balls 5 are movably arranged on the outer side wall of the cylindrical groove 2. A locking ring groove 6 for accommodating the locking balls 5 is formed on the inner wall of the latch groove 3. The auxiliary buffer part includes a buffer outer shell 7, a buffer spring 8, and a locking rod 9. The catapult outer shell 1 and the front cone head 20 are respectively threadedly connected to both sides of the buffer outer shell 7. The buffer spring 8 is inserted into the buffer outer shell 7 and is in contact with the inner wall of the buffer outer shell 7. The locking rod 9 is movably inserted into the buffer spring 8. The locking rod 9 can respectively abut against the cylindrical groove 2 and the front cone head 20. A dial ring 10 is fixedly connected to one end of the locking rod 9 extending into the cylindrical groove 2. The dial ring 10 can push the plurality of locking balls 5 into the locking ring groove 6. A punch rod 11 is movably inserted into the front cone head 20. The punch rod 11 can abut against the locking rod 9.

[0037] Through the above technical scheme, the punch rod 11 is inserted through the front cone head 20, the punch rod 11 conflicts with the locking rod 9, and pushes the locking rod 9 into the cylindrical groove 2. The ring 10 can push the locking ball 5 into the locking ring groove 6, and then the locking ball 5 locks the ring 10 through the relative movement of the locking groove 3 and the cylindrical groove 2 under the action of the locking spring 4, and the locking rod 9 that conflicts with the punch rod 11 is locked. By making the locking groove 3 and the cylindrical groove 2 slide relative to each other, the ring 10 can be unlocked, thereby unlocking the locking rod 9. The locking rod 9 pushes the punch rod 11 to fly out under the action of the buffer spring 8. The overall size of this toy is small, and it can be put in a pocket at will and carried anywhere. It can be taken out at any time when it is needed to play, which is convenient to meet the play needs at any time.

[0038] The end of the punch rod 11 can be provided with a protective device or wrapped with a soft protective layer to prevent the punch rod 11 from causing harm to the human body when it flies out.

[0039] A plurality of circular grooves 12 for accommodating locking balls 5 are provided on the side wall of the cylindrical groove 2, and a plurality of circular holes 13 are provided on the inner and outer walls of the cylindrical groove 2. The circular grooves 12 are connected with the locking ring groove 6 through the circular holes 13 on the inner and outer walls of the cylindrical groove 2. The diameter of the circular holes 13 on the inner wall of the cylindrical groove 2 is smaller than the diameter of the locking balls 5, and the diameter of the circular holes 13 on the outer wall of the cylindrical groove 2 is larger than the diameter of the locking balls 5.

[0040] Through the above technical scheme, when the locking groove 3 and the cylindrical groove 2 move relative to each other, it is necessary to push multiple locking balls 5 into the locking ring groove 6 through the dial ring 10. Since the diameter of the circular hole 13 on the outer wall of the cylindrical groove 2 is larger than the diameter of the locking balls 5, the dial ring 10 can push the locking balls 5 to easily enter the locking ring groove 6. Since the diameter of the circular hole 13 on the inner wall of the cylindrical groove 2 is smaller than the diameter of the locking balls 5, the locking balls 5 can only partially enter the cylindrical groove 2 under the squeezing of the side wall of the locking groove 3. The part of the locking balls 5 that enters the cylindrical groove 2 can block and limit the dial ring 10, thereby restricting the dial ring 10 in the cylindrical groove 2, thereby realizing the locking and unlocking of the locking rod 9.

[0041] The ejection shell 1 is opened at both ends and an ejection stop ring 14 is fixedly connected to the inner wall of one side facing away from the buffer shell 7. The bottom of the locking groove 3 is connected and fixed with an auxiliary groove 15. The auxiliary groove 15 can be slidably connected to the ejection shell 1 and can flexibly abut against the ejection stop ring 14. The outer diameter of the locking groove 3 is larger than the inner diameter of the ejection stop ring 14. The locking spring 4 can abut against the inner bottom of the auxiliary groove 15, and the bottom of the cylindrical groove 2 movably abuts against the end of the locking spring 4 facing away from the auxiliary groove 15.

[0042] Through the above technical solution, the locking rod 9 is pushed to drive the dial ring 10 to enter the cylindrical groove 2, and the multiple locking balls 5 arranged circumferentially are pushed to be squeezed into the locking ring groove 6. When the dial ring 10 reaches the bottom of the cylindrical groove 2, the locking rod 92 pushes the auxiliary groove 15 to conflict with the ejection stop ring 14. The ejection stop ring 14 can prevent the locking groove 3 and the cylindrical groove 2 from sliding out of the ejection shell 1, and at the same time expose the bottom of the auxiliary groove 15, so that the auxiliary groove 15 can be moved to unlock when the punch rod 11 is ejected.

[0043] The center lines of the locking groove 3 and the auxiliary groove 15 coincide with each other, and the auxiliary groove 15 is superimposed on the bottom of the locking groove 3. The two are connected and their center lines coincide with each other, which can ensure that the locking spring 4 remains in a straight state when squeezed by the cylindrical groove 2, ensuring that the locking rod 9 can be fully locked.

[0044] The locking rod 9 includes an extended thick rod 91 and a locking thin rod 92, which are coaxially fixedly connected. The end of the extended thick rod 91 facing away from the locking thin rod 92 is vertically fixedly connected to a pushing platform 16. The pushing platform 16 can be movably extended out of the buffer shell 7 and movably abut against the inner wall of the front cone head 20. The shifting ring 10 is fixedly connected to the end of the locking thin rod 92 facing away from the extended thick rod 91. The shifting ring 10 can slide out of the buffer shell 7 and movably abut against the inner wall of the cylindrical groove 2.

[0045] A buffer pad 17 is connected to the push platform 16, and a buffer groove 18 adapted to the buffer pad 17 is provided on the inner wall of the front cone head 20, and the buffer pad 17 is movably abutted in the buffer groove 18. When the punch rod 11 is ejected, the ring 10 pushes the locking ball 5 into the locking ring groove 6 to release the lock under the action of the buffer spring 8, and the extended thick rod 91 and the push platform 16 located thereon quickly move toward the position of the front cone head 20 under the action of the buffer spring 8. When the push platform 16 rushes into the front cone head 20, the buffer groove 18 can conflict with the push platform 16, thereby leaving the locking rod 9 in the front cone head 20 and the buffer shell 7, and only the punch rod 11 is allowed to fly out, which is convenient for the next loading of the punch rod 11. The buffer pad 17 can reduce the impact when the push platform 16 collides with the buffer groove 18, avoids the front cone head 20 from breaking after long-term use, and prolongs the service life of the toy.

[0046] One end of the buffer spring 8 close to the ejection housing 1 is sleeved with an anti-slip blocker 19, which is arranged on the inner wall of the buffer housing 7, and the locking thin rod 92 is movably inserted in the anti-slip blocker 19, and the extended thick rod 91 can abut against the anti-slip blocker 19. When the buffer spring 8 is compressed under the movement of the extended thick rod 91, the anti-slip blocker 19 supports the buffer spring 8 to prevent the end of the buffer spring 8 from abutting against the buffer housing 7 and twisting and deforming, and can also block the displacement of the buffer spring 8 to prevent the buffer spring 8 from being squeezed out, so as to ensure that the locking thin rod 92 and the dial ring 10 can be locked in the cylindrical groove 2 to complete the ejection operation.

[0047] When a portable ejection toy is used, a punch rod 11 is inserted into the overall toy through a front cone head 20. The inserted punch rod 11 pushes the extended thick rod 91 and then pushes the locking thin rod 92 from the buffer shell 7 into the ejection shell 1. The dial ring 10 pushes a plurality of circumferentially arranged locking balls 5 to be squeezed into the locking ring groove 6 during the process of entering the cylindrical groove 2. When the dial ring 10 reaches the bottom of the cylindrical groove 2, the locking thin rod 92 pushes the auxiliary groove 15 to conflict with the ejection stop ring 14. At this time, the locking groove 3 and the cylindrical groove 2 move relative to each other to push the locking ball 5 that has extended into the locking ring groove 6 back into the circular groove 12, so that the locking ball 5 is close to the circular hole 13 on the inner wall of the cylindrical groove 2, so that the dial ring 10 is pushed back into the circular hole 13. The steel ball blocks the restriction, and the buffer spring 8 is compressed in the buffer shell 7. At this time, the punch rod 11 is inserted into the buffer shell 7 and the ejection shell 1 and locks the locking rod 9 that contacts it; the other punch rods 11 are used to push the auxiliary groove 15 to move toward the buffer shell 7. At this time, the locking groove 3 and the cylindrical groove 2 move relative to each other again. Under the elastic force of the buffer spring 8, the dial ring 10 can push the locking ball 5 to enter the locking ring groove 6 again. In the process of restoring the original length, the buffer spring 8 drives the locking thin rod 92 and the dial ring 10 to pop out quickly from the cylindrical groove 2. The extended thick rod 91 pushes the punch rod 11 under the action of the elastic force and sends it out after quickly passing through the buffer shell 7 and the front cone head 20, so that the punch rod 11 can fly out of the buffer shell 7. Example 2

[0048] Except for the following distinguishing technical features, the rest of the same parts as Example 1 are not repeated here.

[0049] A plurality of circular grooves 12 are provided on the side wall of the cylindrical groove 2, and the locking ball 5 is movably arranged in the corresponding circular groove 12. The inner cavity of the locking cylindrical groove 2 includes a telescopic cavity 21 and a accommodating cavity 22. The diameter of the accommodating cavity 22 is larger than the diameter of the telescopic cavity 21. A V-shaped cavity 23 is formed at the connection between the accommodating cavity 22 and the telescopic cavity 21. A limiting spring 24 is provided in the accommodating cavity 22. A limiting ball 25 is connected to the end of the limiting spring 24 close to the buffer shell 7. The limiting ball 25 is movably arranged in the V-shaped cavity 23 and the accommodating cavity 22. When the limiting ball 25 is located in the V-shaped cavity 23, it can conflict with the locking ball 5, and the dial ring 10 can conflict with the limiting ball 25. A ball placement hole 26 is also provided on the side wall of the cylindrical groove 2, and the ball placement hole 26 is connected to the accommodating cavity 22.

[0050] Through the above technical solution, the limiting sphere 25 is restricted from passing through the sphere placement hole 26 and placed into the accommodation cavity 22. At this time, the limiting spring 24 in the accommodation cavity 22 can make the limiting sphere 25 be abutted in the V-shaped cavity 23. At this time, the locking sphere 5 abuts against the side wall of the locking groove 3 and does not enter the locking ring groove 6. The locking sphere 5 can be blocked by the limiting sphere 25, so that the locking sphere 5 can partially enter the cylindrical groove 2, thus preventing the locking sphere 5 from falling off from the circular groove 12.

[0051] The punch rod 11 is inserted into the front cone head 20, so that the punch rod 11 pushes the extension thick rod 91 and the locking thin rod 92 to move within the buffer housing 7, compressing the buffer spring 8. When the locking thin rod 92 drives the collar 10 thereon to extend into the cylindrical groove 2, the collar 10 pushes a plurality of locking spheres 5 into the locking ring groove 6. After the collar 10 contacts the limiting sphere 25 and continues to push the limiting sphere 25 to move, the limiting spring 24 is further compressed to push the cylindrical groove 2 to move. The cylindrical groove 2 continues to move within the locking ring groove until the edge of the locking ring groove 6 pushes the locking sphere 5 back into the circular groove 12 and partially into the cylindrical groove 2. At this time, the locking sphere 5 blocks the collar 10, so that the locking rod 9 can be locked into the circular ring groove.

[0052] When another punch rod 11 is used to push the auxiliary groove 15 to move towards the buffer housing 7, the locking groove 3 and the cylindrical groove 2 move relative to each other, and the buffer spring 8 is compressed to push the cylindrical groove 2 to move, so that the limiting sphere 25 can push the collar 10 to push the locking sphere 5 into the locking ring groove 6 again. At this time, the buffer spring 8 quickly returns to its original length, driving the locking rod 9 to fly out of the cylindrical groove 2, thereby pushing the punch rod 11 to fly out. Embodiment 3

[0053] Except for the following distinguishing technical features, the parts that are the same as those in Embodiment 1 will not be elaborated here.

[0054] The diameter of the opening of the cylindrical groove 2 is smaller than the outer diameter of the collar 10 and can accommodate the telescopic movement of the locking rod 9. The inside of the cylindrical groove 2 is arranged in a T shape. The collar 10 is movably connected to the inside of the cylindrical groove 2. Two semi-circular protrusions 27 are symmetrically arranged on the inner and outer side walls of the cylindrical groove 2. The semi-circular protrusions 27 are adapted to the locking ring groove 6 and are in the same plane as a plurality of locking spheres 5. A plurality of accommodation grooves 28 penetrating to the opening are formed on the side wall of the cylindrical groove 2. Each locking sphere 5 is arranged in a corresponding accommodation groove 28. A limiting rod 29 is fixedly connected to each locking sphere 5. The limiting rod 29 is fixedly connected to the bottom of the accommodation groove 28, and the limiting rod 29 can be deformed.

[0055] Through the above technical solution, the diameter of the opening of the cylindrical groove 2 is smaller than the outer diameter of the collar 10. When the locking rod 9 is not inserted into the cylindrical groove 2, a plurality of locking spheres 5 connected with the limiting rods 29 are all closely attached to the inner side wall of the locking groove 3 and do not enter the locking ring groove 6.

[0056] When the punch rod 11 is inserted into the front cone head 20, the punch rod 11 pushes the locking rod 9 to move within the buffer housing 7, causing the buffer spring 8 to be compressed. The locking thin rod 92 extends into the cylindrical groove 2. When the dial ring 10 contacts the opening of the cylindrical groove 2, it starts to push the cylindrical groove 2, which is spaced into several sections by the receiving grooves 28, to move outwardly in the circumferential direction, so that the dial ring 10 can enter the cylindrical groove 2. As the dial ring 10 moves, it gradually pushes the locking ball 5 into the locking ring groove 6. At this time, the limiting rod 29 undergoes a slight deformation and tilt relative to the cylindrical groove 2. When the dial ring 10 passes through the position of the locking ball 5, the limiting rod 29 returns to its original state, thereby restricting the dial ring 10 within the cylindrical groove 2 and further achieving the locking of the locking rod 9.

[0057] When other punch rods 11 push the auxiliary groove 15, the auxiliary groove 15 moves towards the buffer housing 7, and the locking groove 3 and the cylindrical groove 2 move relative to each other. At this time, the dial ring 10 abuts against the plurality of locking balls 5 again, and the locking balls 5 are pushed into the locking ring groove 6 again. At the same time, the limiting rod 29 undergoes a deformation and tilt. As the dial ring 10 continues to move, the dial ring 10 disengages from the locking balls 5, and the limiting rod 29 returns to its original state. At this time, under the action of the buffer spring 8, the dial ring 10 flies out of the front cone head 20 at high speed.
