Abstract

The utility model, which provides one kind, can keep permanent sharp electric hammer flat chisel, including installing handle, and one end of the installing handle is equipped with work department；The two sides of the work department are symmetrically arranged with two adjustment bars, and 2 times of the thickness with a thickness of the work department on any cross section per the adjustment bar, so that the rate of wear of the work department and two adjustment bars of two sides is consistent, keep concordant with the work department per the adjustment bar, to guarantee that flat chisel described in the utility model is sharp for a long time, working efficiency is improved, reduces frequency of maintenance, maintenance cost is reduced, is improved service life.

Description

It is a kind of to keep permanent sharp electric hammer flat chisel

[technical field]

The utility model relates to flat chisels, especially a kind of to keep permanent sharp electric hammer flat chisel.

[background technique]

In building field, it is often necessary to it uses flat chisel and carries out excavating work, usually flat chisel is mounted on electric hammer and is used, it is flat The working method of chisel is reciprocating impact by chisel object.As depicted in figs. 1 and 2, the work department 4 of existing flat chisel is in same cross section On thickness it is equal, after a period of use, it is easy to wear, and existing flat chisel work department 4 abrasion both sides grind Damage it is fast, centre abrasion it is slow, and the speed of both sides abrasion is about intermediate twice；So that work department is in arc after flat chisel abrasion Shape causes the effective impact area of the work department 4 of existing flat chisel when in use to reduce, that is, sharpness is reduced, to reduce Working efficiency.

[utility model content]

To overcome defect existing for existing equipment, permanent sharp electric hammer can be kept to use the utility model lies in that providing one kind Flat chisel keeps two adjustment bars concordant with the end of work department, to ensure that length so that two adjustment bars are consistent with work department abrasion It is sharp long, service life is greatly improved, working efficiency is improved.

The utility model is realized in this way: one kind can keep permanent sharp electric hammer flat chisel, including installing handle, described One end of installing handle is equipped with work department；The two sides of the work department are symmetrically arranged with two adjustment bars, and every on any cross section 2 times of the thickness with a thickness of the work department of the adjustment bar, the length per the adjustment bar are equal to the length of the work department Degree, and connected with the installing handle.

Further, the width of the work department is 2.3cm, length 5cm, and the end thickness of the work department is 1.5mm simultaneously prolongs the position that thickness is extremely connected with the installing handle gradually as 2mm；Width per the adjustment bar is 2mm.

Further, the width of the work department is 4cm, length 5cm, and the end thickness of the work department is 1.5mm simultaneously prolongs the position that thickness is extremely connected with the installing handle gradually as 2mm；Width per the adjustment bar is 3mm.

Utility model has the advantages that the utility model, which provides one kind, can keep permanent sharp electric hammer flat chisel, Including installing handle, one end of the installing handle is equipped with work department；The two sides of the work department are symmetrically arranged with two adjustment bars, and 2 times of the thickness with a thickness of the work department on any cross section per the adjustment bar, so that the work department and two sides The rate of wear of two adjustment bars is consistent, so that two adjustment bars are concordant with the work department, to guarantee Permanent sharp, the raising working efficiency of flat chisel described in the utility model, reduces frequency of maintenance, reduction maintenance cost, and raising makes Use the service life.

[Detailed description of the invention]

The utility model is further described in conjunction with the embodiments with reference to the accompanying drawings.

Fig. 1 is the structural schematic diagram of the existing flat chisel in background technique.

Fig. 2 is that the existing flat chisel in background technique uses the schematic diagram after abrasion.

Fig. 3 is the structural schematic diagram of flat chisel described in the utility model.

Fig. 4 is the A-A cross-sectional view of Fig. 3.

In figure: 1, installing handle；2, work department；3, adjustment bar；4, the work department of existing flat chisel.

[specific embodiment]

It please referring to shown in Fig. 3 and Fig. 4, the utility model, which provides one kind, can keep permanent sharp electric hammer flat chisel, including One end of installing handle 1, the installing handle 1 is equipped with work department 2；The two sides of the work department 2 are symmetrically arranged with two adjustment bars 3, and 2 times of the thickness with a thickness of the work department 2 on any cross section per the adjustment bar 3, the length per the adjustment bar 3 It is connected equal to the length of the work department 2, and with the installing handle 1.In use, flat chisel described in the utility model is passed through institute It states installing handle 1 to be mounted on electric hammer, since thickness of two adjustment bars 3 on any cross section is all the work department 2 2 times of thickness, so that the rate of wear of the work department 2 and two adjustment bars 3 of two sides is consistent, so that described The end of work department and two adjustment bars 3 keeps concordant, to guarantee the permanent sharp of flat chisel described in the utility model, mentions High working efficiency reduces frequency of maintenance.

Embodiment one: the width of the work department 2 is 2.3cm, length 5cm, and the end thickness of the work department 2 is 1.5mm simultaneously prolongs the position that thickness is extremely connected with the installing handle 1 gradually as 2mm；Width per the adjustment bar 3 is 2mm.

Embodiment two: the width of the work department 2 is 4cm, length 5cm, and the end thickness of the work department 2 is 1.5mm simultaneously prolongs the position that thickness is extremely connected with the installing handle 1 gradually as 2mm；Width per the adjustment bar 3 is 3mm, Ke Yizuo For the use of big flat chisel.

The utility model has the beneficial effects that two adjustment bars 3 keep abrasion consistent with the work department 2, ensure that flat Chisel it is permanent sharp, improve work efficiency and service life.

Although those familiar with the art answers the foregoing describe specific embodiment of the present utility model Working as understanding, we are merely exemplary described specific embodiment, rather than for the limit to the scope of the utility model Fixed, those skilled in the art modification and variation equivalent made by the spirit according to the utility model all should Cover in the scope of the claimed protection of the utility model.
