Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather should be construed as broadly as the present invention is capable of modification in various respects, all without departing from the spirit and scope of the present invention.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, the present embodiment provides a plant nematode grasping apparatus, including a first grasping cover 200, a second grasping cover 210 and a handle 100, where the handle 100 includes a first movable member 110 and a second movable member 120, the first movable member 110 is connected to one end of the second movable member 120, a free end of the first movable member 110 is a first connecting portion, a free end of the second movable member 120 is a second connecting portion, the first connecting portion is connected to the first grasping cover 200, and the second connecting portion is connected to the second grasping cover 210.

Specifically, the connecting end of the first moving part 110 and the second moving part 120 is welded, so that the stability of the arm is improved, the other end, namely the first connecting part and the second connecting part, is elastically opened when being naturally placed, when the first moving part 110 and the second moving part 120 are squeezed by hands, the first connecting part and the second connecting part are close to each other, and after the force is removed, the first moving part 110 and the second moving part are restored to the initial state under the action of the elastic restoring force.

The first movable piece 110 and the second movable piece 120 are two long strips with narrow sections, wide middle sections and uniform overall thickness, the narrow sections and the wide sections are in arc transition, the wide sections are used for pinching, and the portion used for pinching is wider relative to the two ends, so that pinching and force application are facilitated.

Specifically, the first movable member 110 and the second movable member 120 have a length of 14-20 cm, a thickness of 2-3 mm, a narrow portion of 4-5 mm, and a wide portion of 8-10 mm. In other embodiments, the above parameters can be modified within a reasonable range according to actual use requirements.

The wide portion outside of first moving part 110 and second moving part 120 is provided with anti-skidding line 130, and anti-skidding line 130 sets up to the bump line in this embodiment, and the bump of this bump line is even setting up, sets up the direction and becomes 50-60 with the extension direction of first moving part 110 and second moving part 120, and anti-skidding line 130 can strengthen feeling and stability when holding between the fingers, prevents the phenomenon of dropping that produces because of the hand is smooth in the experimentation. In other embodiments, the anti-slip texture 130 may be replaced with other textures.

The first grabbing cover 200 and the second grabbing cover 210 are net covers, and each net cover can be composed of a net ring and a gauze arranged on the net ring, wherein the aperture of the gauze is smaller than the body shape of the plant nematode. The mesh ring is fixedly connected to the free ends of the movable members (first movable member 110 and second movable member 120). Specifically, the aperture of the gauze is 0.8-1.2 mm, and in other embodiments, the aperture of the gauze can be selected according to observation experiments, so that observation of plant nematodes is not affected.

Because the first movable part 110 and the second movable part 120 can be close to each other or keep away from each other, therefore the first cover 200 and the second cover 210 of snatching can be closed space and the formation of keeping away from each other and snatch between the mouth activity each other, when being in and snatching a mouthful state, can use this device to snatch the plant nematode, wait to grab the back, with the first cover 200 of snatching with the second cover 210 of snatching close and form closed space, with its activity under the condition of not injuring the plant nematode to can improve observation efficiency.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
