Abstract
The utility model relates to an impact spade, which belongs to the tool for digging pit and flattening and is composed of a main body and accessories. The inner front end of an outer sleeve (8) is provided with an impact head (4), the middle part is provided with an impact bar (7) which is sheathed with a spring (6), the back end is provided with a beat bar (13), so the main body (3) is formed. The accessories (1) is a drill bit and a sweep blade and is connected with the impact head (4) of the front end of the main body (3) through a screw bolt (2). While in use, the left hand holds the outer sleeve, the right hand takes a beat bar, and the impact spade is repeatedly impacted forcibly. The utility model has the advantages of small size, light repeat, large impact force, safe use and convenient carrying, and is suitable for digging pit, flattening, removing waste floor tile and wall brick, etc., in the building industry and the fitment industry.
Description
The utility model relates to digs a pit, hole, etc., evens out instrument, particularly a kind of Impact spade.
In the prior art building industry, decorative craft dig a pit, hole, etc., even out and root out waste and old ground wall brick, mainly be with iron chains head, drill rod, waste time and energy with this instrument, effect is poor.
The purpose of this utility model is: a kind of Impact spade of digging a pit, hole, etc., even out and rooting out waste and old ground wall brick that is applicable to building industry, decorative craft is provided, and this Impact spade not only volume is little, and is in light weight, and easy to use, and impulsive force is big.
Formation of the present utility model: form by main body and annex two parts, main body is by impacting head, spring and making bar and form, be connected together with overcoat, annex is bore bit, grafter, overcoat (8) is a cylindrical shape, installs at the Inner Front End of overcoat (8) and impacts head (4), and be the impact bar (7) that is with spring (6) in the back of impacting head (4), in the rear end of overcoat (8), install and make bar (13), form main body (3); Annex (1) is connected on the impact head (4) of main body (3) front end by bolt (2).Impacting head (4) is cylindrical shape, has on cylinder perforation (16), has in the overcoat (8) that impacts head (4) rear end and cylindrical shape positioning sleeve (5) that impact bar (7) cooperates.Impact bar (7) is cylindrical, fixed supporting sleeve (9) on the outside cylinder of impact bar (7) rear end.In stretching into overcoat (8), beat on bar (13) cylinder fixedly stop collar (11), suit sponge sebific duct (14) on the afterbody cylinder of making bar (13), tail end at sponge sebific duct (14) is installed lid (15), has and beat the annular plug (12) of bar (13) cooperation in the rear end of overcoat (8).
Compared with the prior art, the utlity model has that volume is little, in light weight, impulsive force is big, only need one man operation, safe and reliable, easy to carry, long service life.
Accompanying drawing 1 is the utility model shape assumption diagram;
Accompanying drawing 2 is the utility model main structure charts.
Embodiment of the present utility model: as shown in drawings, overcoat (8) is a cylindrical shape, suit plastic sheath (10) on the cylindrical of overcoat (8), fixed punch tap the head (4) on the front end endoporus of overcoat (8), the front end that impacts head (4) stretches out outside the overcoat (8), at the tail end that impacts head (4) the cylindrical shape positioning sleeve (5) that is installed in the overcoat (8) is arranged, impact bar (7) is installed in the rear end overcoat (8) that impacts head (4), the fixing splicing sleeve (9) that cooperates with overcoat (8) endoporus on the rear portion cylinder of impact bar (7), the anterior cylindrical of impact bar (7) cooperates with positioning sleeve (5) endoporus, pocketed springs on the outside cylinder of impact bar (7) (6), spring (6) are positioned between positioning sleeve (5) and the splicing sleeve (9).
It is cylindrical making bar (13), clamping rings shape stop collar (11) on the cylindrical of front end, the cylindrical of stop collar (11) cooperates with the endoporus of overcoat (8), annular plug (12) is arranged in the tail end hole of overcoat (8), the endoporus of plug (12) cooperates with the cylindrical of making bar (13), stretching out the suit sponge sebific duct (14) on bar (13) outside cylinder of beating of overcoat (8) afterbody, lid (15) is being installed at the afterbody of sponge sebific duct.Annex (1) is connected on the impact head (4) of main body (3) front end by bolt (2).
During use, left hand is held overcoat, and the right hand is taken and to be made bar, firmly impacts head (4) repeatedly, by with impact the annex (1) (bore bit, grafter) that head (4) is connected, can be over the ground, wall enforcement digs a pit, hole, etc., hole and backing-off cutting.
Impact spade divides large, medium and small three kinds of specifications, can produce the temporary impact load of 9～14Kg during manual operations, spring plays cushioning effect, minimizing is applied mechanically flexible plastic moulding package outward to the impact shock of human body, makes bar and holds part and adopt frosted expanded rubber pipe to encase, use comfortable feel, annex is furnished with the shovel head of many types of bore bit and multiple shape, all uses the steel alloy Quenching Treatment, long service life.Impact spade is safe and reliable, can not cause the personal injury.
