What is the history of agriculture hand tools and garden hand tools?

Hand tools are small tools that are held by hand and controlled by human or human hands. For hand cutting and auxiliary decoration. Generally, they are equipped with handles for easy carrying. 

Hand tools are a tool of transforming and conquering nature, which are produced and developed at the same time with human beings. The original hand tools were very simple, such as wooden sticks, stones with edges and corners, etc. Hammers began to use more complex hand tools after people could process stones or animal bones into stone axes, stone knives and bone needles. In 4000 BC, the emergence of metallurgical technology promoted the separation of agriculture and handicraft industry, and also improved the manufacturing of hand tools. Modern hand tools still retain the characteristics of the original hand tools, such as the pliers created in 300 A.D. and the whole set of spanners used to tighten the screws, which are still in use today. This is the agricultural hand tools .

With the development of modern mechanical and metallurgical technology, hand tools are constantly updated and developed in modeling design, material use and other aspects, fully considering the design factors such as mechanics and human function; with the development of social economy and the close division of industrial production, the manufacturing of hand tools is more specialized and diversified, such as on-board tools and electronic instrument assembly Tools and garden hand tools and other special supporting hand tools. 

Manual tool is a relative conceptual classification, which mainly refers to the difference between machine or automatic driven tools. It is named for its manual driving mode. Some tools can be used by hand or installed on machines or automatic mechanisms, so there is no strict distinction between tools themselves .

Hand tools can be divided into cutting tools and decoration AIDS according to their functions, and can be divided into screw and nut assembly hand tools (such as spanners, screw screwdrivers), construction hand tools, gardening hand tools (scissors, sickles, haycutters, tree shears, etc.), pipeline hand tools, measurement hand tools, woodworking hand tools, welding hand tools, etc. according to their uses. Common tools include hammers, files, knives, pliers, saws, screwdrivers, wrenches and diamond tools.

How to buy power tools?

Precautions when purchasing power tools: First, the power tool is a hand-held or movable mechanized tool that is powered by an electric motor or an electromagnet and drives the working head through a transmission mechanism. Power tools are easy to carry, simple to operate, and feature-rich. They can greatly reduce labor intensity, improve work efficiency, and realize manual operation and mechanization. Therefore, they are widely used in construction, housing decoration, automobile, machinery, electric power, bridge, gardening and other fields. And enter the family in large numbers.

The power tool is characterized by light structure, small size, light weight, low vibration, low noise, flexible operation, easy control and operation, convenient to carry, strong and durable. It can increase labor productivity several times to tens of times compared with manual tools; it is more efficient, less expensive and easier to control than pneumatic tools.

1, Different household or professional use according to needs. Most power tools are designed for professionals. When purchasing, they should distinguish between professional and general household tools. Usually, the difference between professional and general household tools is in power. Professional tools are more powerful, so that professionals can reduce the workload. The tools used in general households are relatively small, and the workload is relatively small. Therefore, the input of tools is relatively small. Power does not need to be large;

(3) Operators should hand over tools between hand, do not throw. When passing a tool with a sharp edge, turn the handle toward the person receiving it.

(4) For crowbars and other shoulderborne tools, pay attention to the front and back when carrying, so that it does not touch other objects and personnel, put down to be stable.

(5) When carrying portable power tools with flexible cord, it is necessary to protect the flexible cord so as to keep it away from sharp objects, heat sources, oil or solvents so as not to damage the flexible cord.

2. Safety precautions for the handle of manual tools:

(1) the handle of the tool hit by the hammer is prone to local fracture when it is hit for a long time. A metal collar (bronze ring) should be installed on the end of a chisel, punch, rock drill, etc.

(2) For the manual tools with wooden handle, the wooden handle should be made of tough hardwood (such as oak, elm, walnut, locust, maple, etc.). The handle should be smooth and free of knots, cracks and other defects, Such as chipping hammers.

(3) The connection between the wooden handle and the hammerhead and axe must be solid and firm, in case the wooden handle is broken or the hammerhead flies out during use, if the handle is found to be loose in use, it must be wedged tight immediately. It is more important to fit the wooden handle with the hole of the equipment.

(4) To prevent the wooden handle spinning and slipping in the hand, the wooden handle should be oval.

3. Cut the hose nozzle, install the tip tube, and cut it according to the size of the joint at a 45° angle.

4. Install the caulking gun and keep the rubber at the 45° angle along the gap to ensure that the rubber is in close contact with the surface of the substrate. When the seam width is greater than 15 mm, it is necessary to apply the glue repeatedly. After the glue is applied, the surface is trimmed with a knife to remove excess glue, and then the tape is torn off. If there is stain, it can be removed with a damp cloth.

5. The sealant is vulcanized after 10 minutes at room temperature. It takes 24 hours or more to completely vulcanize, depending on the thickness of the glue and the temperature and humidity of the environment.
