Description

Flexible hoe

(1) technical field:

The utility model relates to flexible hoe, divides by International Patent Classification (IPC) (IPC) to belong to human life need part, agriculture branch, agricultural; Forestry; Livestock breeding; Hunt; Trapping; Fish big class, the whole ground of agricultural or forestry; Parts, part or the annex group of general agricultural machinery or farm implements, the technical field of hand-operated tools group.

(2) background technology:

At present, the technology about the hand-operated tools group existing and that once had was all done very fruitful effort to the demand of flexible hoe, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Ye Ruiru, Granted publication number is CN2225940Y, China Patent No. (ZL) is: No. 95211640.5 utility model patent title is the utility model patent of " handle of garden tool set ", the technical scheme that is adopted, technical elements in the hand-operated tools group is a routine of great value invention, and it has solved manual arable land technical problem easily effectively.But still have some deficits, its also be difficult to solve volume big, take up space, be fit to different crowd, can make the technical problem of spud.

(3) summary of the invention

The purpose of this utility model is to provide a kind of flexible hoe.With solve volume big, take up space, be fit to different crowd, can make the technical problem of spud.

The new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is: flexible hoe of the present utility model mainly is made of bonnet, shell, anti-slide plate, interior axle, screw, tine head.

In shape, structure and combination thereof, the total essential features of flexible hoe of the present utility model and immediate prior art is: the lower surface position cover of anti-slide plate is installed in the middle upper end position of shell, the outer surface position of axle in the inner chamber position cover of shell is installed in, be combined into the bascule of straight-bar shape, function has been to realize the flexible effect of axle.The lower position of axle in the upper position weldering of tine head is connected, the top integral position of interior axle is inserted in the lumen position of shell, is combined into the fixed structure of straight-bar shape, and function has been the effect of loading hoe.In shape, structure and combination thereof, the flexible hoe of the present utility model technical characterictic different with immediate prior art is: the lower surface position weldering of bonnet is connected the upper port position of shell, the outer integral position of axle in the inner chamber position cover of shell is installed in, be combined into the fixed structure of straight-bar shape, function has been the effect that prevents to enter rainwater.The precession end position screw thread of screw is installed in the front middle part hole site of shell, and the groove position in the screwhole position of shell is installed in screw on the axle of axle is combined into erose bascule, and function has been the effect of the fixed-site of axle in making.The solution volume that has so just reached flexible hoe of the present utility model is big, take up space, and is fit to different crowd, can make the purpose of the technical problem of spud.

The beneficial effect of the flexible hoe of utility model is: the utility model for solve volume big, take up space, be fit to different crowd, can make the technical scheme that technical problem adopted of spud and compare two place's advantage and improvement with the technology that once had about the hand-operated tools group with existing:

First, because the lower surface position weldering that has designed bonnet in the technical scheme of flexible hoe of the present utility model is connected the upper port position of shell, the outer integral position of axle in the inner chamber position cover of shell is installed in, be combined into the fixed structure of straight-bar shape, so easier solution prevents to enter the technical problem of rainwater.

Second, because the precession end position screw thread that has designed screw in the technical scheme of flexible hoe of the present utility model is installed in the front middle part hole site of shell, groove position in the screwhole position of shell is installed in screw on the axle of axle, be combined into erose bascule, so easier solution makes the technical problem of the fixed-site of interior axle.

(4) description of drawings:

Accompanying drawing provides the structural representation of flexible hoe of the present utility model:

Fig. 1: the overall structure schematic diagram that is flexible hoe of the present utility model;

The label declaration at each position in the schematic diagram:

Axle 5 screws 6 tine heads in 1 bonnet, 2 shells, the 3 anti-slide plates 4

(5) embodiment:

Below in conjunction with accompanying drawing, to flexible hoe of the present utility model for realize to solve volume big, take up space, be fit to different crowd, the optimal way that can make the technical scheme that the technical problem of spud takes is described further:

Its static structure: see also accompanying drawing; As shown in the figure, flexible hoe of the present utility model mainly is made of bonnet 1, shell 2, anti-slide plate 3, interior axle 4, screw 5, tine head 6.Its major part bonnet 1, anti-slide plate 3, screw 5, tine head 6 are selected for use by market.Its shell 2 is that hole shape is arranged at circle shell and top, is material with iron, through casting, the manufacturing of boring processing and forming.Its interior axle 4 is screw thread hole shapes that concavity is arranged on the axis, is material with iron, through casting, turning moulding processing and manufacturing.

In shape, structure and combination thereof, the total essential features of flexible hoe of the present utility model and immediate prior art is: the lower surface position cover of anti-slide plate 3 is installed in the middle upper end position of shell 2, the outer surface position of axle 4 in the inner chamber position cover of shell 2 is installed in, be combined into the bascule of straight-bar shape, function has been to realize the flexible effect of axle.The lower position of axle 4 in the upper position weldering of tine head 6 is connected, the top integral position of interior axle 4 is inserted in the lumen position of shell 2, is combined into the fixed structure of straight-bar shape, and function has been the effect of loading hoe.In shape, structure and combination thereof, the flexible hoe of the present utility model technical characterictic different with immediate prior art is: the lower surface position weldering of bonnet 1 is connected the upper port position of shell 2, the outer integral position of axle 4 in the inner chamber position cover of shell 2 is installed in, be combined into the fixed structure of straight-bar shape, function has been the effect that prevents to enter rainwater.The precession end position screw thread of screw 5 is installed in the front middle part hole site of shell 2, and the groove position in the screwhole position of shell 2 is installed in screw 5 on the axle of axle 4 is combined into erose bascule, and function has been the effect of the fixed-site of axle in making.

Below by using method, further set forth the dynamic structure relation of flexible hoe of the present utility model: in use, when needs the time with big hoe, according to theory of mechanics, at first screw 5 is unscrewed, axle 4 is tightened screw 5 more then to the appropriate location in extracting then, thereby finishes the task of using big hoe.

In use, when needs account for little space, according to theory of mechanics, at first unscrew screw 5, axle 4 in advancing then screws screw 5 more then, thereby finishes the task of saving the space.The solution volume of so just having realized flexible hoe of the present utility model is big, take up space, and is fit to different crowd, can make the technical scheme of the technical problem of spud.

Realize that preferred plan of the present utility model is is material with iron, utilize the basic equipment of ironwork factory, take to produce by batch on a small scale,, so just can realize the practical value and the economic worth of flexible hoe of the present utility model better with the demand of supply family circle.
