Abstract
The invention discloses an electric drill safe in use. The electric drill comprises a shell, a drill bit and a protective cover, wherein the protective cover comprises a sleeve and a handle, the sleeve is connected to the shell and the drill bit in a sleeved mode in the axial direction and can rotate and move on the shell in the axial direction, the handle is installed on the radial surface of the sleeve, and the sleeve is made of a transparent material. The electric drill is quite safe in use.
Description
Technical field
The invention belongs to field of power tools, be specifically related to a kind of safe electric drill that uses.
Background technology
Traditional electric drill is in the time of the upper punching of object (template or metal) or stubborn screw, in the time that object is really up to the mark or drill bit has not aimed at screw, may make drill bit or broken screw fall or flick, splashing out easily makes operating personnel injured, uses not exclusively.
Summary of the invention
(1) technical problem that will solve
The technical problem to be solved in the present invention is to propose to be with sleeved electric drill, has solved in conventional art screw or drill bit and has splashed out and easily make the problem that operating personnel are injured.
(2) technical scheme
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind ofly use safe electric drill, comprise shell, drill bit and protective cover; Described protective cover includes sleeve and handgrip, and described quill is to being socketed on shell and drill bit, and can axial-rotation and movement on shell, and described handgrip is arranged on the sagittal plane of sleeve, and the material of described sleeve is transparent material.
Further also comprise chi bar, setscrew nut, positioning sleeve and fixed block; Described positioning sleeve is socketed on shell, and contacts to cooperation with quill, and one end of described chi bar is fixedly connected with positioning sleeve, and the other end is plugged on fixed block, and described setscrew nut is threaded with chi bar and coordinates and contact with fixed block.
The structure of described chi bar is thread spindle, and chi bar rear and front end is plane, is provided with in the plane graduation mark.
Described handgrip is quality of rubber materials.
The material of described sleeve is transparent plastic material.
(3) beneficial effect
The electric drill that use of the present invention is safe, by a protective cover is set, be arranged in protective cover in the position of drill bit or screw, therefore can prevent after drill bit or screw extraction bullet fly still in protective cover, therefore can prevent that operating personnel are injured, improved security performance, and can control the drilling depth of drill bit by chi bar, function shape is powerful.
Brief description of the drawings
Fig. 1 is the structural representation of the safe electric drill of use of the present invention while not using;
Fig. 2 is the structural representation of the safe electric drill of use of the present invention while using;
Fig. 3 is the cutaway view of A-A in Fig. 1 of the present invention;
In figure, 1 is that shell, 2 is that drill bit, 3 is that protective cover, 4 is that sleeve, 5 is that handgrip, 6 is that chi bar, 7 is that setscrew nut, 8 is that positioning sleeve, 9 is that fixed block, 10 is plane.
Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for illustrating the present invention, but are not used for limiting the scope of the invention.
As shown in figures 1 and 3 a kind of uses safe electric drill, comprises shell 1, drill bit 2 and protective cover 3; Described protective cover 3 includes the handgrip 5 of sleeve 4 and quality of rubber materials, described sleeve 4 is axially socketed on shell 1 and drill bit 2, and can axial-rotation and movement on shell 1, described handgrip 5 is arranged on the sagittal plane of sleeve, and the material of described sleeve 4 is transparent plastic material.Can make drill bit 2 or screw be arranged on the inner side of sleeve 4 by this structure, even if drill bit 2 or screw extraction can not fly to outside yet and make staff injured, strengthen security performance, and sleeve 4 is rotatable, thereby can make operating personnel rotate and put handgrip 5 arbitrarily, more convenient to operate.
The safe electric drill of use of the present invention also has deep hole severity control function, and its concrete structure comprises chi bar 6, setscrew nut 7, positioning sleeve 8 and fixed block 9; Described positioning sleeve 8 is socketed on shell 1, and axially coordinates and contact with sleeve 4, and one end of described chi bar 6 is fixedly connected with positioning sleeve 8, and the other end is plugged on fixed block 9, and described setscrew nut 7 is threaded with chi bar 6 and coordinates and contact with fixed block 9.The structure of described chi bar 6 is thread spindle, and chi bar rear and front end is plane 10, in plane 10, is provided with graduation mark.After drill bit contacts with object plane with sleeve 4 with object plane, making fixed block 9 is initial value at the numerical value of chi bar 6, and setscrew nut 7 is rotated with fixed block 9 and contacted, then according to the degree of depth in hole, make push rod mobile corresponding distance backward, it can be according to the calculating of getting on of the scale of chi bar 6 apart from length, finally just setscrew nut 7 rotation contacts with fixed block 9, therefore in use after sleeve 4 contacts with object plane, process the degree of depth of portalling, operation is very easy, powerful.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
