Description

A few font pincers

Technical field

A few font pincers, are exclusively used in the nail pulling out on the trunk of gardens.

Background technology

In afforestation, gardener is for the tree in fixation cultivation is because translating into appears in wind rain brush, so just tiltedly prick in ground with one end of batten or bamboo pole, the other end nails on trunk.Like this, large tree is planted and has lived, and has but forever left some nail youngsters on trunk.

Because these seat height that are retained in the nail place trunk on trunk differ, the passage in time in addition, peg is corrosion gradually, or is that trunk has been embraced nail youngster firmly at leisure among vitality.As time goes by, thus tend to allow that people is not worth mentioning has faded from memory as so micro-unknown thing.In fact, as gardener, necessarily should pass over the seat height of nail youngster on trunk, all these should be followed closely to youngster and pull up.Tree is the thing of life, just as people's body, in human body, how to hold thorn?

While stroll in the gardens of Wo community, when seeing the thing of residual nail youngster on some trunks, can't forbid the breath of will sighing.In our new campus, the thing that leaves like this nail youngster on trunk is also simply customary.So I catch student am carried out to the machine that labour skill are taught subsidiary course training and oneself administered the initiative of school's functional compartments through conscientiously thinking, have invented a few font pincers that are exclusively used in the nail pulling out on the trunk of gardens.

At present, owing to not having such nail pulling apparatus to sell on market, reason is: I have run a lot of hard ware stores and have removed to buy the instrument pulling out a nail, but storekeeper all look smug or conceited and do not have, be then do one's utmost suggestion I buy nail hammer, steel wire clamp or carpenter's pincers use.I expect interconnected online purchase among difficult, the instrument that my seen nail pulling is used on the internet, and the one, price, the 2nd, also to rely on the device that electric energy could use, in general, be unsatisfactory.So I have produced a thought: be suitable for the pincer of gardens demand, the one, should be conveniently with carry, the 2nd, not the electric power and practical, this wouldn't find pleasure in.

In the time of half a year, I am on the one hand in continuous thinking, and in one side, Baidu does current awareness search work repeatedly.The time of half a year has gone over, and I utilize and start development free time, although experienced failure again and again, has finally produced a few font pincers.

A few font pincers are made up of carpenter's pincers, a few word pincers, pulley, steel wire rope, wire stretching wheel, spring, strut.It is characterized in that: English walnut clamp is put to a few word pincers.Doing is like this just not damage trunk cortex pulling out nail childhood on trunk, is as far as possible ideally to extract the nail left behind on trunk.On a few font pin due to a few font pincers, there is V word mouth, so a few word pin of a few font pincers can directly be used as nail pulling, the strong point also can be used as nail pulling time.Several prefixs have been installed the pulley that can transform tractive force, and the race of pulley is laid steel wire traction rope.When pressing lower stretching wire wheel, the jaw of carpenter's pincers closes; Use one one power of closing inwardly to press on tendentiousness ground again when holding the power arm of carpenter's pincers, under the spring tension and compression of strut on several words angle on carpenter's pincers power arm, on the zigzag vertical bar of the oblique angle of pole point on carpenter's pincers power arm, move, thereby whole English walnut clamp is raised up.English walnut clamp puts a few word pincers, on a few prefix M of a few word pincers, be embedded with two pulleys that stack, the steel wire rope in the clamp handle of carpenter's pincers is connected to by the race of pulley in the wire casing of wire stretching wheel, and power arm one end of carpenter's pincers is connected on protruding English walnut shape belly with axle.The corresponding tooth bar of a few font pincer power arms is grown 36 centimetres, and 0.8 centimetre, zigzag face is wide; On the position of power arm handle 20 centimeter length, wire stretching wheel is installed.Power arm is installed tension spring in 14 centimeters of English walnut shape one end of carpenter's pincers sawtooth, and the strut at several words angle of a few word pincers is tiltedly square vertical bars of point of band.The reclining horizontal plane of Saw blade of strut, the horizontal plane of Saw blade faces the oblique point of strut, and strut is long 4 centimetres of the inclined-plane of point tiltedly, and oblique angle 15 is spent, and the length of side of square vertical bar strut is 2 centimetres, long 30 centimetres.

Therefore, a few font pincer nail pulling great advantage are: the principle work the nail of nail on trunk with draft, customer service cross a poly-injury trunk bark layer difficult problem.
