Description

A kind of folding sickle

Technical field

The utility model relates to a kind of agricultural tools, is a kind of folding sickle specifically.

Background technology

In the vast rural area of China, reaping hook was widely used a lot of years as a kind of crops harvesting tool, and China is one of maximum country of this kind farm implements usage amount, and these farm implements are robbed for crops and to be retracted into positive role in the harvesting operation.

At present; Along with the raising of Chinese economic development and people's living standard, outdoor exercises have become the favorite that people cultivate the moral character and nourish the nature with the fishing outdoor activity, and traditional reaping hook also becomes indispensable instrument in these motions; Because in fishing and outdoor exercises; People usually will clear up weedy plot, make it to become movable desirable land used such as fishing and picnic, so just be unable to do without reaping hook.

Traditional reaping hook great majority are all-in-one-piece structures; It is all scientific and reasonable inadequately and can't be widely used though people also attempt to process folding reaping hook structure owing to structure; 1., bulky there are a lot of shortcoming and defect in use in all-in-one-piece reaping hook, is in particular in:, waste raw material; It is big when the harvesting operation, to consume one's strength, and efficiency is low.2., because cutter head is exposed outside, so the inconvenience of carrying, poor stability is unfavorable for that particularly long distance carries.3., most designs of traditional reaping hook and process coarsely, if use refiningly inadequately as the open air of non-farm implements and fishing appurtenance, be difficult to accepted by the high colony of this consumption level.

Summary of the invention

The objective of the invention is to provide a kind of simple and reasonable, volume is little, processing and refining, folding sickle easy to carry, that safety is good.

The purpose of the utility model is to realize like this; This reaping hook comprises cutter head and handle of a knife; It also comprises a cutter head folding device that is connected between cutter head and the handle of a knife, and described cutter head folding device comprises folding device main body, locking bar, sliding button, hold-down screw and return spring, and wherein locking bar is arranged on the folding device body interior that has sliding eye; Return spring is contained on the locking bar, and the hole on the corresponding folding device main body of sliding button is connected with locking bar through hold-down screw.

Also the handle of a knife folding device can be set on the described handle of a knife; Described handle of a knife folding device comprises left side Connection Block, right side Connection Block, left sliding pin, right sliding pin, connecting pin and symmetrical snaggletooth bolt; Wherein the left side Connection Block constitutes with stiff end handle and the big link of diameter by diameter is little; Link has the endoporus of a taper; Symmetry snaggletooth bolt is arranged on the bottom of the endoporus of taper, the stiff end of handle and the link center that has symmetrical snaggletooth bolt have one the perforation of left sliding pin is set endoporus; The right side Connection Block constitutes with stiff end handle and the big link of diameter by diameter is little, and wherein link is a pyramidal structure, is provided with symmetrical snaggletooth screw thread in it, stiff end and link center have one the perforation of right sliding pin is set endoporus; Described connecting pin is hinged between left sliding pin and the right sliding pin.

Described cutter head folding device is arranged on an end of handle of a knife, and through being threaded, has flat mouthful that cutter head is set on the cutter head folding device, on the cutter head folding device, also has the hole of placing sliding button.

One end of two grooves of the corresponding cutter head tail end of described locking bar has a convexity, realizes the folding and unlatching of cutter head through the change in location of locking bar raising between a groove and another groove.

The utility model is owing to adopt said structure to have the following advantages:

1, owing between cutter head and handle of a knife, set up the cutter head folding device, make cutter head to turn over and turn 90 degrees that blade is towards handle of a knife one side, people have more safety when carrying, avoided unnecessary incised wound, have also dwindled the volume of reaping hook simultaneously.

2, owing on handle of a knife, set up the handle of a knife folding device, make handle of a knife become the structure of present two-segment type by traditional integral structure, when not using, it is decomposed and folding its volume is dwindled more, it is more convenient to carry.

3, because the folding design in above-mentioned two places of product of the present invention; Make this reaping hook product structurally more exquisite; Not only can satisfy the needs of vast farmers; And the fan with outdoor exercises of can being fit to go fishing pursues the requirement of elaboration apparatus, is a reaping hook high-end product that adaptability is very wide.
