Detailed ways

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

Embodiment 1

Referring to Figures 1, 2 and 3, a picker with a spiral knife comprises a shell 1, a micro motor 2 is arranged inside the shell 1, a micro motor 2 switch 9 is arranged on the shell 1, the micro motor 2 is fixedly connected to one end of a moving knife tube 5, a notch 6 is provided on the side wall of the other end of the moving knife tube 5, a stationary knife tube 7 is arranged outside the moving knife tube 5, one end of the stationary knife tube 7 is connected to the micro motor 2, and a spiral knife 8 is arranged on the other end, and the micro motor 2 is connected to a power supply device.

The power supply device may be a rechargeable battery (not shown) built into the housing, or an external power source (not shown) connected via a power plug.

The connection mode between the micro motor 2 and the movable knife tube 5 can be that the transmission shaft 3 of the micro motor 2 is fixed to the side wall of the movable knife tube 5 by the centering screw 4 or other fixed connection modes. When in use, the switch 9 of the micro motor 2 on the housing 1 is started. When the micro motor 2 rotates, the movable knife tube 5 is driven to rotate in the direction of the spiral knife 8. The stem of the cut object (such as pepper, flower or fruit) passes through the spiral knife 8 to reach the notch 6 of the movable knife tube 5. The notch 6 and the spiral knife 8 form a cutting, and the cut object (such as pepper, flower or fruit) is cut. The incision is smooth and has no sawtooth, and a large amount of leaves will not fall or branches will be damaged.

The inner diameter of the static blade tube of the invention can be designed to be 10-12mm, making the invention smaller in size, lighter in weight, and less power-consuming. The spiral blade of the static blade tube is smaller and has a guiding function, making it easy to capture pepper or flower buds or fruit stems and place them in the cutting position. The static blade tube and the rotating moving blade tube form a scissor-like cutting, and the motor has high effective work. When designing the invention, the moving blade tube and the static blade tube can be designed to be disassembled, and the scope of application is wide.

Embodiment 2

On the basis of the first embodiment, the spiral blade 8 includes a spiral blade body 81 and a spiral blade 82. The spiral blade 82 can form a large shear force with the notch 6, and the object to be cut (such as pepper, flower or fruit) can be cut with little effort. The spiral blade body 81 is higher than the spiral blade 82 in order to better guide the branches to capture the object to be cut (such as pepper, flower or fruit) and prevent the branches from being damaged.

Embodiment 3

On the basis of the first embodiment, the notch 6 of the movable blade tube 5 is U-shaped, rectangular or V-shaped. The notch design can accurately capture the object to be cut (such as pepper, flower or fruit). In order to increase the effective work, the side wall of the notch can be designed to be sharpened on both sides.

Embodiment 4

On the basis of the first embodiment, the inner side of the other end of the moving blade tube 5 is sharpened. The inner side refers to the inner wall, which is to better form a shearing fit with the moving blade tube 5 and prevent children from accidentally hurting themselves when playing.

Embodiment 5

On the basis of the above-mentioned fourth embodiment, the outer side of the spiral blade 82 is sharpened. The outer side refers to the side of the spiral blade facing the user when the invention is used, so as to better form a shearing match with the inner side of the movable blade tube 5, so as to facilitate the shearing of the cut object (such as pepper, flower or fruit).

Embodiment 6

On the basis of the fifth embodiment, the cross section of the spiral blade 82 and the movable blade tube 5 forms an acute angle, so that the spiral blade 82 and the movable blade tube 5 form a shearing action, which is convenient for shearing the cut object (such as pepper, flower or fruit), and the acute angle setting can be designed according to the diameter of the cut object.

Embodiment 7

On the basis of the first embodiment, a USB interface is provided on the housing 1, and the USB interface is connected to the power supply device. Since users use the picker to pick peppers, flowers or fruits outdoors for a long time, it is easy for the mobile phone they carry with them to run out of power. The mobile phone can be plugged into the USB interface through a data cable, and the power supply device can charge the mobile phone.

Embodiment 8

On the basis of the first embodiment, a picker with a spiral blade further includes a photovoltaic panel (not shown), and the photovoltaic panel (not shown) is connected to a rechargeable battery (not shown). The solar energy is fully utilized to supply power to the rechargeable battery to save power, and the rechargeable battery provides a power source for the micro motor.

In addition, an LED lamp (not shown) and a light sensor (not shown) can also be provided on the housing 1, and the LED lamp (not shown) is connected to the light sensor (not shown), and a rechargeable battery (not shown) is connected to the light sensor (not shown). The solar panel converts light energy into electrical energy to supply power to the rechargeable battery, and the rechargeable battery provides a power source for the micro motor and a power source for the LED lamp. The light sensor controls the LED lamp according to the lighting conditions, and the LED lamp automatically emits light in the dark environment to provide a lighting function. When it is cloudy or dusk and the light is dark, the light sensor starts the LED lamp, which is convenient for users to better pick the cut objects (such as pepper, flowers or fruits).

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
