The spherical hinge 8 is arranged near the center of gravity of the operating rod 9, which can not only effectively support the operating rod 9, but also take into account the overall center of gravity. At the same time, it does not occupy too much area of the fruit storage cart 1, and also leaves room for the net pocket 11 as the fruit drop channel. space.

As shown in Figure 2, the net bag 11 is made of flexible materials, including: a mesh surface 111, a middle buffer surface 112 and a bottom buffer surface 113, wherein: the mesh surface 111 is surrounded into a column shape, and several middle buffer surfaces are arranged in the mesh surface 111. surface 112 and a bottom buffer surface 113.

The middle buffer surface 112 is provided with an oval opening, and several openings are provided between the edge of the oval opening and the mesh surface 111, which can be opened and closed when the fruit rolls and impacts, so as to change the size of the opening, so that the fruit slides smoothly. can also act as a buffer;

Preferably, the elliptical openings are arranged at asymmetric positions on the middle buffer surface 112 .

The bottom buffer surface 113 is a semicircular opening, which is misaligned with the oval opening, so as to prevent the fruit from falling directly and being damaged.

As shown in Figures 1 and 4, the operating rod 9 includes: a telescopic rod 91, a connecting wire 92, a control handle 93 and a lifting button 94, wherein: the control handle 93 and the lifting button 94 are arranged at the bottom of the telescopic rod 91, and the telescopic The top of the rod 91 is fixedly connected to the counter 12 , the connecting piece 13 is fixedly connected to the counter 12 , and the connecting line 92 is connected to the connecting piece 13 .

The connecting wire 92 is preferably arranged in the operating rod 9, and can also be fixed outside the telescopic rod 91 with a cable tie.

As shown in Fig. 1 and Fig. 3, described cutter 10 comprises: base 101, double fixed blade 102, single-action blade 103 and rotating shaft 104, wherein: base 101 is fixed on one end of connector 13, and base 101 is fixed on There are double fixed blades 102 and rotating shaft 104 arranged up and down, and the single-action blade 103 is fixedly connected with the other end of the connector 13, and is rotatably connected with the rotating shaft 104.
