When the pecans are picked, the branches do not need to be beaten, and when people pick the pecans, the supports 23, the support rods 21 and the tarpaulin 22 are well built, so that the plurality of supports 23 and the support rods 21 surround the pecans, and then the tarpaulin 22 is connected with the support rods 21 through the fixing rings 221 and the lifting hooks 211. Meanwhile, one end of the support rod 21, which is abutted against the trunk, is slightly inclined downwards, so that the whole enclosed surface is in an inverted umbrella shape. A collecting bag for collecting the pecan fruits is arranged below the trunk, namely below one end of the downward inclined part of the tarpaulin 22, the tarpaulin 22 is also arranged obliquely due to the inclined arrangement of the supporting rod 21, and after the pecans fall on the tarpaulin 22, the pecans slide downwards along the inclined direction of the tarpaulin 22 and are drawn into the collecting bag arranged below. When the pecans in the collecting bag are full, the collecting bag can be directly lifted away, and the operation is very quick. People can not pick the hickory nut on the tree, and the hickory nut falls on the ground all the time, and people need collect the hickory nut on the ground after picking, so that the appearance of the hickory nut is not only affected, and meanwhile, the time is spent on collecting the hickory nut on the ground. The presence of the collecting device avoids the above-mentioned disadvantages. Before the control power supply 13 is turned on, the position and direction of the telescopic rod 11 are adjusted to enable branches with pecans to be located between the first roller 51 and the second roller 52, when the control switch 14 is turned on, the first fixing tube 41 and the second fixing tube 42 on the opening and closing device 4 are close to each other due to the fact that the electromagnet 62 is electrified to generate magnetic force, the first roller 51 and the second roller 52 clamp the branches, and meanwhile the first roller 51 and the second roller 52 are also electrified to roll. At this time, the telescopic rod 11 is gradually pushed and moved to displace the first roller 51 and the second roller 52 and roll while being displaced. The pecans on the branches are clamped and pushed, and due to the shearing force generated by rolling of the first roller 51 and the second roller 52, the pecans on one branch can fall quickly and fall onto the tarpaulin 22, and finally slide into the collecting bag, so that the efficiency is improved. Therefore, people do not need to knock the branches, so that the branches are influenced, and the harvest in the next year is influenced. Meanwhile, when the telescopic rod 11 is moved, the first roller 51 and the second roller 52 roll to generate a shearing force on the hickory nut, so that people do not need to spend a large amount of effort to pick the hickory nut from the telescopic rod 11, and the hand force of people is greatly reduced. Meanwhile, due to the existence of the telescopic rod 11, people do not need to climb to the hickory nut and the branch to pick the hickory nut, and accidents are greatly reduced.

As a modified specific embodiment, a return spring 61 is provided at a side of the first fixed tube 41 opposite to the second fixed tube 42, one end of the return spring 61 is connected to the first fixed tube 41, and the other end is connected to the second fixed tube 42, when the control switch 14 is closed, the first fixed tube 41 and the second fixed tube 42 are close to each other and the return spring 61 is compressed, and when the control switch 14 is opened, the return spring 61 is reset and the first fixed tube 41 and the second fixed tube 42 are away from each other by an elastic force. When picking pecans, people stretch the pecans far by the telescopic rod 11 and make branches on the first roller 51 and the second roller 52. When the telescopic rod 11 extends the first fixing tube 41 and the second fixing tube 42 to branches, the first fixing tube 41 and the second fixing tube 42 are hinged to each other, so that the first fixing tube 41 and the second fixing tube 42 are close to each other, the first roller 51 and the second roller 52 are also close to each other, the branches are difficult to enter the space between the first roller 51 and the second roller 52, people need to shake the telescopic rod 11 to separate the first fixing tube 41 and the second fixing tube 42, the first roller 51 and the second roller 52 are far away from each other, and the branches enter the space between the first roller 51 and the second roller 52. However, people feel tired by shaking the telescopic rod 11 from time to time, and meanwhile, if people climb to the tree to swing the telescopic rod 11, picking personnel are easy to fall down due to unstable gravity center, and casualties are caused. The existence of the return spring 61 enables the first fixing tube 41 and the second fixing tube 42 to be in a V shape on the whole under the state that the control switch 14 is not closed, and branches can smoothly enter between the first roller 51 and the second roller 52. When the control switch 14 is closed, the first fixing tube 41 and the second fixing tube 42 are attracted by the magnetic force generated by the electromagnet 62. The magnetic force is greater than the elastic force of the return spring 61, so that the first rollers 51 can be close to each other to clamp branches, and roll to pick pecans. However, when the control switch 14 is turned off, the magnetic force generated by the electromagnet 62 disappears, and the elastic force of the return spring 61 makes the first fixing tube 41 and the second fixing tube 42 move away from each other, so that the first roller 51 and the second roller 52 move away from each other and can be separated from the tree branches to go to the next tree branch for picking.

The pecan trees are so tall that some pecans are closer to the picker and some are far from the picker. If the telescopic rod 11 is too long, although the pecans at far positions can be picked, when the pecans at relatively near positions are picked, the telescopic rod 11 often collides with branches on trees, and picking personnel are prevented from picking the pecans. When the telescopic rod 11 is too short, although picking the pecans at the near position is more convenient, the pecans at the far position cannot reach the telescopic rod, and picking personnel need to climb forwards continuously, so that accidents are easy to happen. The outer tube 112 is sleeved outside the inner tube 111, and the inner tube 111 can slide in the outer tube 112 to adjust the overall length of the telescopic rod 11. The existence of first logical groove 113 makes the mouth of pipe of outer tube 112 can realize tightening up, realizes adjusting the orificial elasticity of outer tube 112 through adjusting the distance between two stationary blades 63 to play the length of fixed telescopic link 11, prevent that sudden elongation or shortening can appear when using telescopic link 11.
