Abstract

The invention discloses a lever spade. The lever spade comprises a spade rod, wherein a spade head is mounted at the front end of the spade rod; a movable U-shaped support frame is mounted on the spade rod through a screw; the spade rod is a telescopic rod; the front end of the spade head is saw-toothed; and a hook is arranged on the spade rod, and a hang hole is formed in the U-shaped support frame. When the lever spade is in use, the U-shaped support part is put up to turn the soil under the lever action; as the telescopic rod is adopted, more physical strength can be saved; and when the saw-toothed spade head is used for the soil with more stones and sand grains, the damage probability of the spade head is lowered and the service life is prolonged accordingly.

Description

A kind of lever spade

Technical field

The present invention relates to a kind of spade, especially a kind of utilization labour-saving lever spade that gets up.

Background technology

At present, generally in agricultural of carrying out fraction and the whole ground of forestry, great majority need to adopt spade to turn over whole; If run into harder whole just relatively having required great effort turning in soil; Running into this time usually foundary weight spade bar downwards, adopt the principle of lever that earth is dug, could earth be dug but must the spade bar be pressed onto the end like this; The amplitude that operating personnel bend over is very big, has wasted very big muscle power.

Summary of the invention

Technical problem to be solved by this invention provides a kind of suitable labour-saving lever spade that uses.

The present invention solves the technical scheme that its technical problem takes: a kind of lever spade, comprise the spade bar, and spade bar front end is equipped with the spade head, the U type bracing frame through screw installation activity on the described spade bar.

When relatively require great effort in whole ground, in order better to save muscle power, what described spade bar adopted is expansion link.

In order to make spade better on some have the soil of more stony and the grains of sand, use the zigzag fashion that described spade head front end adopts.

In order not use U type bracing frame conveniently to settle, described spade bar is provided with hook, and U type bracing frame is provided with hanging hole.

The invention has the beneficial effects as follows: when in use U type support member is propped; Through leverage earth is dug, adopted expansion link to save muscle power more, the shovel head of zigzag fashion is used on the more soil of stone and the grains of sand; Reduce the infringement of shovel head, increase the service life.

Description of drawings

Fig. 1 is a structural representation of the present invention;

Fig. 2 is a utilization structure sketch map of the present invention.

Among the figure: 1, spade head 2, hanging hole 3, spade bar 4, screw 5, U type bracing frame 6, hook.

Embodiment

A kind of lever spade as depicted in figs. 1 and 2 comprises spade bar 3, and spade bar 3 front ends are equipped with spade head 1, passes through the U type bracing frame 5 of screw 4 installation activities on the described spade bar 3; What described spade bar 3 adopted is expansion link; The zigzag fashion that described spade head 1 front end adopts; Described spade bar 3 is provided with hook 6, and U type bracing frame 5 is provided with hanging hole 2.

When in use, firmly spade head 1 is inserted in the earth, then U type bracing frame 5 is taken down from linking up with 6; Be placed on the ground; The spade bar 3 that will have telescopicing performance is extracted out, and one of downward foundary weight spade bar 3 then, spade head 1 will be with earth to come out; Laborsaving convenience, work continue only need to repeat above-mentioned action and get final product.

It is emphasized that: above only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction; Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.。
