To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description of the preferred embodiments of the present invention will be given with reference to the accompanying drawings. In the following description, different "one embodiment" or "an embodiment" refers to not necessarily the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Example 1
A ball pick-up device as shown in fig. 1, the ball pick-up device comprising: the net basket comprises a net basket 1, wherein the net basket 1 is composed of a plurality of high-elastic steel wires 10 and mounting plates at two ends of the high-elastic steel wires 10, the high-elastic steel wires 10 are axially arranged, first ends of the high-elastic steel wires 10 are fixed through a first mounting plate 11, and second ends of the high-elastic steel wires 10 are fixed through a second mounting plate 12; the net basket comprises a rotary connecting frame 2, wherein the rotary connecting frame 2 comprises a first connecting end 21 and a second connecting end 22, the first connecting end 21 is rotatably connected with the first mounting plate 11, the second connecting end 22 is rotatably connected with the second mounting plate 12, and the net basket 1 can rotate on the rotary connecting frame 2; and is configured to: after the high-elastic steel wire 10 is extruded by the mounting plate, the middle section deforms towards the side far away from the rotating shaft; the distance between two adjacent high-elastic steel wires 10 at the deformation position is L, the diameter of the ball to be picked is D, 1/2D is less than L and less than D, and the ball to be picked can enter the net basket 1 from the space between the two high-elastic steel wires 10.
In this embodiment, the ball pickup device further includes a handle 3, and the handle 3 is connected to the rotary connecting frame 2. When the ball picking device is used, the basket of the ball picking device is pushed to rotate by holding the handle 3 by hands, so that the function of picking balls is realized.
The interlude is to keeping away from the pivot side takes place deformation, that is to say, the cross-sectional area of the interlude of basket 1 is greater than far away from the area of mounting panel, thereby makes basket 1 is when rolling, and the part that contacts ground is the interlude. Ball pickup attachment's basket 1 is fixed the back by the mounting panel (being first mounting panel 11 and second mounting panel 12 respectively) at both ends, forms a shape of a similar wax gourd or long lantern.
High-elastic steel wire 10 sets up along the axial, the mounting panel that only leans on both ends of high-elastic steel wire 10 is fixed, consequently, swing easily takes place under the effect of power in high-elastic steel wire 10 interlude to change the distance between the adjacent high-elastic steel wire 10.

The tensile force of the flexible cord 44 resists the tensile force of the high elastic steel wire 10 to maintain the basket 1 in a predetermined shape. When the high-elasticity steel wire 10 extends to be a straight line, the other end of the soft rope 44 can be in a free state (i.e. does not pass through the mounting hole), and when the high-elasticity steel wire 10 needs to be deformed, the hook passes through the mounting hole and then is hooked in a specific limiting piece; when the high-elastic steel wire 10 is stretched to be a straight line, the hook of the soft string rope 44 may also pass through the mounting hole, and the length of the soft string rope 44 is equal to that of the high-elastic steel wire 10, so that the hook does not fall off.
In specific implementation, the flexible rope 44 is a multi-braided flexible steel wire rope or a thick nylon rope or an inelastic plastic rope.
Mounting plate spacing adjustment assembly design 7:
design 7 lies in with the difference of design 6, and at two mounting panels inboards, respectively have two rings symmetric distribution on the mounting panel, apart from centre bore 20mm, the first end of many plaiting wires is equipped with anticreep spare, and the second end has two couples (a couple is at many plaiting wires end, another distance end 30 ~ 50mm department). When the multi-braided soft steel wire anti-falling device is installed, the multi-braided soft steel wire anti-falling device is fixed with one of the circular rings of the first installation plate 11, the second end of the multi-braided soft steel wire penetrates through the two circular rings on the second installation plate 12, and then the winding hook is hung in the other circular ring of the first installation plate 11. Two couples are according to the use needs, select any couple to hang in the ring, because two couples have 30 ~ 50 mm's distance between the distance, consequently can adjust the distance between two mounting panels to the realization is picked up the ball of different diameters. Due to the elasticity of the high-elasticity steel wires 10, the shape of the ball-picking net basket 1 and the multi-braided steel wires can be kept in a tight state and can not fall off.
In the design 1-7 of the mounting plate interval adjusting assembly 4, the distance between the mounting plates at two ends of the net basket 1 is adjusted through the telescopic rod 41 or the soft rope 44, the interval between the adjacent high-elastic steel wires 10 is adjusted, and spherical objects with different diameters can be picked up. The smaller the distance between the two mounting plates is, the larger the bending of the steel wires of the net basket 1 is, the larger the gap distance between the steel wires is, and the larger the diameter of the picked ball is. The larger the distance between the two mounting plates is, the smaller the bending degree of the steel wires of the net basket 1 is, and the smaller the gap distance between the steel wires is, so that balls with small diameters can be picked up. The balls with different diameters can be picked up through the mounting plate interval adjusting assembly 4.
