Specific embodiment

To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below In conjunction with the drawings and specific embodiments, the utility model is further described.

As shown in Figures 1 to 5, a kind of tennis pick device, including handle 1, bung 2, cylinder 3 are collected expander 4 and are received Collect pawl 8, the handle 1 is fixedly connected with the bung 2, and the bung 2 is mounted on 3 upper end of cylinder, 3 lower end of cylinder The collection claw 8 is installed, the cylinder 3 and collection 4 elastic connection of expander, the cylinder 3 are hollow cylindrical and internal diameter Greater than the diameter of tennis, the collection claw 8 is divided into claw 11 and connection ring 12 from the bottom to top, and the claw 11 is along connection ring week To being uniformly distributed, the diameter of a circle that the claw end of collection claw is surrounded is less than the diameter of tennis；The collection claw 8 is elasticity knot Structure, and have gap between the collection expander 4.The cylinder 3 includes cylinder solid wall 13, cylinder body outer wall 14 and cylinder Inner wall 15, the cylinder body outer wall 14 form groove 16 with the cylinder inboard wall 15, and the collection expander 4 and the groove 16 are sliding Dynamic grafting, 4 top of collection expander are connect with the bottom of the cylinder solid wall 13 by spring 6, the collection expander 4 Top is to expand ring 17, and lower part is equipped with guide sleeve 7 and Elastic buckle 9；The 16 opening two sides of groove are equipped with inwardly projecting limit Position bulge loop 10, the Elastic buckle 9 is with 10 sliding plug of position limiting convex ring and 9 end of the Elastic buckle is by the limit Bulge loop 10 blocks；There is gap between the Elastic buckle 9 and the guide sleeve 7；Guide post 5 is mounted on 13 bottom of cylinder solid wall On, the guide sleeve 7 and 5 clearance fit of guide post, 6 sets of the spring on the guide post 5；In addition to the spring 6, other portions The material of position is all plastics.

In the present embodiment, there are four along the circumferentially equally distributed pawl 11 of connection ring, the pawl 11 for the collection claw 8 Angle is formed by greater than 60 ° and less than 90 ° with the connection ring 12.

The course of work and principle: device work when, tennis pick device is perpendicular to the ground, collect expander 1 bottom with Ground face contact, tennis are housed in it, push handle 1, under force, cylinder 3 moves down, and collection claw 8 is contacted with tennis；After Continuous to apply active force to handle 1, cylinder 3 continues to move down, and the pawl 11 of collection claw 8 is flared out under force, and elasticity occurs Deformation, when the diameter of a circle that the end of the pawl 11 after deformation is surrounded is greater than the diameter of tennis, tennis enters connection ring 12；Net After ball enters connection ring 12, pawl 11 returns back to rapidly original position；Lifting device collects effect and gravity of the expander 4 in spring 6 Under the action of return back to original position；Next tennis is shifted to, repeats aforesaid operations, after the completion of work, first tennis enters cylinder 3, original position is replaced by second tennis, so after operation repeatedly, when cylinder fastly picked up by full or tennis, cover 2 is opened, by net Ball pours into tennis frame.

Described on base, the utility model structure is simple, easy to operate, reduction labor intensity that can be very big, is not required to bend over Tennis is picked up, it is quality-high and inexpensive.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change It also should be regarded as the protection scope of the utility model into modification.
