[0031] On the basis of the above structure, both the display panel 2 and the ball storage barrel 4 are made of transparent organic glass, and a sealing cover 5 is threadedly sleeved on the outer side of the bottom end of the ball storage barrel 4 .

[0032] In this embodiment, the display panel 2 is provided to facilitate observation of the number of tennis balls collected in the ball storage barrel 4.

[0033] On the basis of the above structure, a ball hole is opened at the bottom end of the collecting tube 1, and multiple groups of grabbing and limiting components 3 are distributed at equal angles around the ball hole at the bottom end of the collecting tube 1.

[0034] In this embodiment, multiple groups of grabbing and limiting components 3 distributed at equal angles are used to facilitate stable grabbing of tennis balls on the ground.

[0035] Based on the above structure, the grabbing limit assembly 3 includes a fixed rod 31, a movable rod 32 and a spring 33. The fixed rod 31 is welded and fixed to the bottom end surface of the collecting cylinder 1. The movable rod 32 is slidably connected inside the fixed rod 31, and a spring 33 is fixedly connected between the fixed rod 31 and the movable rod 32.

[0036] On the basis of the above structure, the movable rod 32 forms an elastic structure inside the fixed rod 31 through the spring 33, and the end of the movable rod 32 located outside the fixed rod 31 extends to below the ball hole at the bottom end of the collecting tube 1, and the bottom of the end of the movable rod 32 located outside the fixed rod 31 is provided with an inclined surface.

[0037] In this embodiment, when grabbing a tennis ball on the ground, the tennis ball can squeeze the inclined surface of the end of the movable rod 32, causing the movable rod 32 to retract toward the inside of the fixed rod 31. When the tennis ball enters the ball storage tube 4, the movable rod 32 can be reset by the spring 33, which can limit the position of the tennis ball to prevent it from falling.

[0038] Based on the above structure, the positioning assembly 6 includes a top cover 61, a handle 62, a connecting tube 63, a boss 64 and a long screw 65. The top cover 61 is located above the collecting barrel 1. The handle 62 is fixedly installed at the middle position of the upper end surface of the top cover 61. The rear outer wall of the top cover 61 is fixed with a connecting tube 63. The bottom rear outer wall of the connecting tube 63 is fixed with a boss 64. The interior of the connecting tube 63 is installed with a long screw 65 through the bearing.

[0039] On the basis of the above structure, the lower half of the connecting tube 63 is located inside the fixed tube 7 and the two are movably connected, and the threaded section of the long screw 65 is threadedly connected to the fixed tube 7 .

[0040] In this embodiment, the lifting and lowering adjustment of the entire positioning assembly 6 is conveniently controlled by manually rotating the long screw 65 .

[0041] Based on the above structure, the end of the boss 64 away from the connecting pipe 63 is guided and slid on the inner side of the guide groove 9. The guide groove 9 includes a vertical section and an inclined section located at the top of the vertical section, and the inclined section is connected to the vertical section.

[0042] In this embodiment, as the positioning assembly 6 rises, when the boss 64 enters the inclined section of the guide groove 9, the boss 64 can drive the connecting tube 63 and the top cover 61 to rotate 90 degrees while rising, thereby facilitating the extraction and disassembly of the ball storage tube 4 and the quick boxing and recycling of the tennis balls.

[0043] The working principle of this utility model is as follows:

[0044] When picking up and collecting tennis balls, the device is first held by the handle 62, and the ball hole at the bottom of the collecting tube 1 is aligned with the tennis ball on the ground. Then, the device is pressed down vertically. At this time, the tennis ball can squeeze the inclined surface of the end of the movable rod 32, causing the movable rod 32 to retract toward the inside of the fixed rod 31. When the tennis ball passes through the ball hole at the bottom of the collecting tube 1 and enters the ball storage tube 4, the movable rod 32 can lose its squeeze and be reset by the spring 33. At this time, the movable rod 32 can limit the tennis ball to prevent it from falling.

[0045] When picking up tennis balls, the display board 2 and the ball storage barrel 4, both made of transparent organic glass, are used to conveniently observe the number of balls stored in the ball storage barrel 4. When the ball storage barrel 4 is full, the long screw 65 can be manually rotated to drive the connecting tube 63 and the top cover 61 to move upward synchronously, so that the top cover 61 leaves the top outer side of the ball storage barrel 4. When the boss 64 enters the inclined section from the vertical section of the guide groove 9, as it continues to move upward, the boss 64 can be pushed by the inclined section of the guide groove 9 to drive the connecting tube 63 and the top cover 61 to rotate 90 degrees synchronously around the long screw 65 as the center, so that the top cover 61 can be turned away from the top of the ball storage barrel 4. Then the device can be turned upside down as a whole, and the ball storage barrel 4 can be pulled out of the collecting barrel 1. The ball storage barrel 4 is then sealed with the cover 5, thereby facilitating the quick boxing and recycling of tennis balls.

[0046] In summary, compared with the comparative documents, this device is smaller in size, lighter in weight, easier to carry and use for picking up balls, and can also avoid damage to the court surface. It is more practical and more economical, and it is convenient to quickly pack and recycle tennis balls, making it easier to properly store and use them later.

[0047] The above are only preferred specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any equivalent changes, modifications, substitutions and variations made by technicians in this technical field based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of existing technologies should be within the scope of protection determined by the claims.
