Abstract

A double-chuck electric hand drill is provided, which is composed of a shell, a main chuck, a two-way running motor with a rotating shaft, and a handle with a main switch which are connected. Wherein, the two-way running motor penetrated with the rotating shaft is fixed in the shell, one end of the rotating shaft penetrates through an opening at one end of the shell to connect with the main chuck, the middle part of the shell is connected with the handle with the main switch which is in the same side with the main chuck, the other end of the shell is arranged with the opening, and the other end of the rotating shaft penetrates through the opening at the other end of the shell to connect with a subsidiary chuck; a subsidiary switch is arranged at the same side with the subsidiary chuck on the handle. Due to the adoption of the technical proposal, the utility model can be arranged two drills synchronously according to the demands of the construction, and any two functions such as boring, extending the hole, arranging (disassembly) the bolt or possessed by other drills can be realized synchronously. The utility model has the advantages of convenient use and operation, high efficacy, time and electricity saving, and overcomes the disadvantage of replacing drills frequently when the traditional electric hand drill is used, and realizes a plurality of functions for one machine.

Description

Two dop electric hand drills

Technical field

The utility model relates to a kind of electric hand drill, particularly a kind of pair of dop electric hand drill.

Background technology

In existing life, no matter the application of electric hand drill is at repairs profession more and more widely, or in the woodwork industry, perhaps other need be used in the industry of electric hand drill, and its advantage light and handy, easy to use of electric hand drill is apparent more outstanding.Electric hand drill can not only provide the function of boring, can realize for example reaming by the drill bit of changing difference in functionality, (dismounting) screw or the like other function is installed, yet present electric hand drill is by casing, dop, the handle of motor and belt switch connects and composes, these electric hand drills have only a dop, often need more bit change repeatedly when realizing difference in functionality, such as the helical form drill bit that in furniture industry, when needing to bore a hole, need hole, at this moment need be on the hole that has just got out have only during mounting screw by as hand tools such as flat mouthful screwdriver or Phillips screwdriver install, yet these hand tools are not only required great effort but also are time-consuming, if will utilize electric hand drill to come mounting screw to change drill bits such as flat mouthful drill bit or cross bit again, waste the time greatly.

The utility model content

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of use simple operation is provided, frequent two dop electric hand drills of changing drill bit shortcoming when having overcome traditional electric hand drill and using.

The technical solution of the utility model is achieved in that a kind of pair of dop electric hand drill, connect and compose by casing, main card head, the handle that has the two-way rotary electric machine of rotating shaft and have a main switch, the two-way rotary electric machine that is installed with rotating shaft is fixed in the casing, the opening that one end of rotating shaft passes casing one end is connected with the main card head, the middle part of casing is connected with having with the handle of the main switch of main card head homonymy, the other end of casing is provided with opening, and the opening that the other end of rotating shaft passes the casing other end is connected with secondary dop; On handle, be provided with auxiliary switch with secondary dop the same side.

Owing to adopt such scheme, the utility model can be installed two drill bits simultaneously according to the construction needs, can realize simultaneously any two kinds such as boring, reaming, installation (dismounting) function that screw or other drill bit had, it uses simple operation, effect height, save time, power saving, the frequent shortcoming of changing drill bit when having overcome traditional electric hand drill and using, and realizes a tractor serves several purposes.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described

Fig. 1 is the utility model structural representation;

Wherein: the 1-casing; 2-main card head; The secondary dop of 3-; The two-way rotary electric machine of 4-; The 5-rotating shaft; The 6-main switch; The 7-auxiliary switch; The 8-handle.

The specific embodiment

As shown in Figure 1, a kind of pair of dop electric hand drill, connect and compose by casing 1, main card head 2, the handle 8 that has the two-way rotary electric machine 4 of rotating shaft 5 and have a main switch 6, the two-way rotary electric machine 4 that is installed with rotating shaft 5 is fixed in the casing, the opening that one end of rotating shaft 5 passes casing 1 one ends is connected with main card head 2, the middle part of casing 1 is connected with having with the handle 8 of the main switch 6 of main card head 2 homonymies, the other end of casing 1 is provided with opening, and the opening that the other end of rotating shaft 5 passes casing 1 other end is connected with secondary dop 3; On handle 8, be provided with auxiliary switch 7 with secondary dop 3 the same sides.

As shown in Figure 1, the utility model adopts main switch 6, the two-way rotary electric machine 4 of auxiliary switch 7 controls to drive main card heads 2, secondary dop 3 clockwise or rotate counterclockwise.For example: in the use when main card head 2 drills are installed, when secondary dop 3 is installed cross bits, press the two-way rotary electric machines 4 in main switch 6 back and drive main card heads 2 acting that moves in the direction of the clock, be used for boring, drive secondary dop 3 simultaneously and counterclockwise rotate acting, can be used for dismounting and withdraw from screw; The direction of the hand-held electric hand drill of counter-rotating, press auxiliary switch 7 after, two-way rotary electric machine 4 drives the acting that moves in the direction of the clock of secondary dop 3, is used for installing advancing screw, drives main card head 2 simultaneously and counterclockwise rotates and do work, and is convenient to withdraw from drill bit.
