Description

A kind of electric hammer drill hammer

Technical field

The utility model relates to wall body hole technical field, specially a kind of electric hammer drill hammer.

Background technique

Drill hammer is a kind of equipment for clamping on electric impact drill, to concrete foundation, wall, brick wall, granite Carry out it is boring, to install expansion bolt, the fasteners such as plastic expansion pipe in hole.

In the prior art, it is to scrap whole drill bit after drill body is broken when boring wall operation, wastes huge；Drill bit is to wall When drilling, the bits of discharge splash everywhere along the rotation of drill bit, hurt the eyes of operating personnel sometimes, therefore, improve electric hammer Drill hammer structure is necessary.

Utility model content

The purpose of this utility model is to provide a kind of electric hammer drill hammers, to solve mentioned above in the background art ask Topic.

To achieve the above object, the utility model provides the following technical solutions: a kind of electric hammer drill hammer, including drill body and Drillstock, in which: setting 3-edge surgical knife is inlayed in one end of the drill body, and connection handle, the connection handle is arranged in the other end of the drill body It is threadedly coupled with drillstock, shank, shield is arranged in the junction of the connection handle and drillstock, and the shank is through connection handle, brill Handle and shield.

Further, tool apron is arranged in the junction of the drill body and 3-edge surgical knife, and there are three inclined-planes for the end face setting of tool apron.

Further, the shield is tubaeform.

Further, the material of the shield is PMMA.

Further, through-hole is set on the connection handle, shank diameter is greater than by diameter.

Compared with prior art, the utility model has the beneficial effects that splitting out shank after 1. drill bodies are broken, more renewing Drill body, it is not necessary that entire impact drill is scrapped, save the cost；2. shield is made into using transparent PMMA material, wall operation is bored When, the bits that can effectively avoid splashing hurt the eyes of operating personnel, meanwhile, wall operation is bored convenient for intuitive observation；3. inclined-plane Design, can make chip removal more smooth, and the utility model has very strong practicability, can be widely popularized.

Detailed description of the invention

Fig. 1 is the utility model main view；

Fig. 2 is the utility model perspective view.

In figure: drill body 1,3-edge surgical knife 2, connection handle 3, inclined-plane 4, drillstock 5, shield 6, shank 7.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of electric hammer drill hammer, including drill body 1 and brill Handle 5, it is characterised in that: setting 3-edge surgical knife 2 is inlayed in one end of the drill body 1, fixes 3-edge surgical knife 2 using welding manner after inlaying, Connection handle 3 is arranged in the other end of the drill body 1, and the connection handle 3 is threadedly coupled with drillstock 5, after drill body 1 is broken, splits out shank 7, the drill body 1 more renewed, it is not necessary that entire impact drill is scrapped, save the cost, the junction of the connection handle 3 and drillstock 5 Shank 7, shield 6 are set, and the shank 7 runs through connection handle 3, drillstock 5 and shield 6.

Tool apron is arranged in junction for the practicability for further promoting this programme, the drill body 1 and 3-edge surgical knife 2, tool apron End face setting is in the prior art right angle there are three inclined-plane 4, and when impact drill operation, bits are easily got lodged in wall hole, are designed to oblique Face can make chip removal more smooth.

For the practicability for further promoting this programme, the shield 6 be it is tubaeform, material PMMA, shield 6 is adopted It being made into transparent PMMA material, when boring wall operation, the bits that can effectively avoid splashing hurt the eyes of operating personnel, meanwhile, it is convenient for Wall operation is bored in intuitive observation.

For the practicability for further promoting this programme, through-hole is set on the connection handle 3, it is straight to be greater than shank 7 by diameter Diameter, convenient for the dismounting of drill body.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
