[0026] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0027] Among them, the drawings are only used for exemplary explanations, and they only show schematic diagrams rather than actual drawings, and cannot be understood as limitations on this patent; in order to better illustrate the embodiments of the utility model, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted, and the same or similar reference numerals in the drawings of the embodiments of the utility model correspond to the same or similar parts; in the description of the utility model, it should be understood that if the terms "upper", "lower", "left", "right", "inner", "outer" and the like appear, the directions or positional relationships indicated are based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, so the terms describing the positional relationship in the drawings are only used for exemplary explanations, and cannot be understood as limitations on this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.
[0028] like Figure 1 - Figure 4 As shown, a picker of the utility model comprises an upper support rod 1, a lower support rod 3 and a gripping portion;
[0029] Wherein, the top of the upper support rod 1 is connected with a picking part 2;
[0030] The lower support rod 3 is coaxially connected to the upper support rod 1;
[0031] The holding part is connected to the bottom of the lower support rod 3, and the holding part has a pressure handle 40, and the pressure handle 40 is connected to a rope body 5. After the pressure handle 40 is acted on, the picking part 2 is pulled closed by the rope body 5. After the pressure handle 40 is released, the picking part 2 returns to its initial state.
[0032] The main part of the rope body 5 is inserted into the upper support rod 1 and the lower support rod 3 , and the two ends of the rope body 5 are connected to the pressing handle 40 and the clamping arm 21 respectively.
[0033] The picker has a knife body 211 disposed on its head to avoid related damage caused by simple pulling. After applying force to the pressure handle 40, the picking part 2 can not only clamp the fruit, but the knife body 211 can also cut off the fruit handle. During use, especially when the fruit is at a higher and farther position, since cutting and clamping of the fruit are completed at the same time, the operation process is relatively convenient.
[0034] The upper support rod 1 and the lower support rod 3 are hollow and can slide relative to each other.
[0035] Specifically, a clamping part 6 is provided at the connection between the upper support rod 1 and the lower support rod 3. When the entire picker needs to be extended, the clamping part 6 is loosened, and the upper support rod 1 or the lower support rod 3 is pulled to extend it. After reaching a suitable length, the clamping part 6 is bent in the opposite direction to lock it. In this way, the length of the picker can be adjusted, and it is convenient to adjust according to the actual height of the fruit during the picking operation.
[0036] Specifically, the picking part 2 includes a positioning arm 20 connected to the upper support rod 1 and a clamping arm 21 rotatably connected to the positioning arm 20 , and the cross-section of the clamping arm 21 is in the shape of a letter "7".
[0037] The positioning arm 20 is provided with a knife body 211 on the side thereof, and the knife body 211 is connected to the clamping arm 21.
[0038] In addition, the opposite sides of the clamping arm 21 and the positioning arm 20 are both arc-shaped. Such an arc-shaped design fits the shape of the apple more closely, increases the contact area of the clamping, and facilitates clamping.
[0039] In addition, a rubber pad 200 is provided on the upper surface of the positioning arm 20. When pulling the fruit, the rubber pad 200 can prevent the positioning arm 20 from directly contacting the fruit, causing damage to the fruit and deterioration of its quality. The side of the clamping arm 21 close to the positioning arm 20 is provided with a serrated side plate 210, and the serrated side plate 210 is preferably symmetrically designed. The serrated structure increases the friction force to prevent the fruit from slipping during the clamping process. The serrated part can be made of rubber or elastic material.
[0040] The above are only embodiments of the utility model. The common sense such as the known specific structures and characteristics in the scheme is not described in detail here. The ordinary technicians in the relevant field are aware of all the common technical knowledge in the technical field to which the utility model belongs before the application date or priority date, can obtain all the existing technologies in the field, and have the ability to apply the conventional experimental means before that date. The ordinary technicians in the relevant field can improve and implement the scheme in combination with their own abilities under the enlightenment given by this application. Some typical known structures or known methods should not become obstacles for the ordinary technicians in the relevant field to implement this application. It should be pointed out that for the technicians in this field, without departing from the structure of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
