In figure: 1, housing; 2, stick of tool head; 3, horizontal sliding bearing; 4, rotational speed control module; 5, trunnion shaft; 6, pressure-strain sheet; 7, LED; 8, press button; 9, power module.
Detailed description of the invention
Reaching for setting forth the utility model further the technological means and effect that predetermined object takes, below in conjunction with drawings and Examples to detailed description of the invention of the present utility model, architectural feature and effect thereof, being described in detail as follows.
Embodiment 1:
In order to overcome the shortcoming that existing electric hand drill in use exists: first, in use, often encountering in the object plane of needs punching, causing the vestige that some collide, especially some effects on surfaces require higher article; Secondly, electric hand drill not only needs the punching controlling electric hand drill in use, and needs controlled drilling rate, and this allows operator be difficult to when operating control electric drill accurately; Be exactly that existing electric drill does not arrange lighting device in addition, under some dim environment, often there is the dead angle of illumination in particularly large factory building, operator needs to reconfigure lighting apparatus, very inconvenient like this.
The utility model provides a kind of electric hand drill as shown in Figure 1, comprise housing 1, be arranged at the rotational speed control module 4 in housing 1, power module 9, trunnion shaft 5, be arranged at the stick of tool head 2 of housing 1 outside, also comprise the pressure-strain sheet 6 being arranged at housing 1, be arranged on the horizontal sliding bearing 3 of stick of tool head 2 leading portion, and be embedded in the LED 7 on housing 1; Described horizontal sliding bearing 3 is fixedly installed on stick of tool head 2 section of top, and described pressure-strain sheet 6 is connected by wire with rotational speed control module 4, for by pressure signal, is converted to the signal of telecommunication, adjustment rotating speed; Described horizontal sliding bearing 3 is fixedly connected with stick of tool head 2, for cushioning the impact force of electric hand drill; Described LED 7 is electrically connected with power module 9 by wire.
Above-mentioned housing 1 is also provided with press button 8, and described press button 8 is serially connected in the connection line of LED 7 and power module 9, for controlling the on off state of LED 7; This press button 8 is arranged on above housing 1, near the place of LED 7, and not only handled easily, and the normal use that electric hand drill can not be disturbed.
Above-mentioned pressure-strain sheet 6 is arranged at the inner side of trunnion shaft 5, and the extruding force that trunnion shaft 5 is subject to passes to pressure-strain sheet 6, and described pressure-strain sheet 6, is converted to the signal of telecommunication by pressure signal, is sent to rotational speed control module 4 by wire; Pressure-strain sheet 6 is very close with existing pressure-controlled rotating speed mode operation principle of pressing, and maximum difference is exactly change in drill process operator's finger presses into extrude generation pressure.
The height of above-mentioned horizontal sliding bearing 3 is higher than the top of stick of tool head 2, if the height of horizontal sliding bearing 3 just cannot play lower than stick of tool head 2 effect that object plane collision that protection punches produces vestige.
Above-mentioned horizontal sliding bearing 3 is that soft elastomeric material is made, and can play the effect of damp impacts like this, thus avoids the material producing impact marks the most frequently used to be made up of rubber.
This electric hand drill, can prevent from use colliding in the object plane of needs punching, avoid the vestige causing some to collide, especially some effects on surfaces require higher article, can avoid very well occurring impact marks; And this electric hand drill design consideration applied pressure size and change rotating speed, not only change operator and should control rotating speed and also will take into account the quality of punching and the situation of precision, reduce the operation requirements of operator; And the LED arranged on electric hand drill can meet the needs of illumination, under some dim environment, particularly large factory building, in the face of the dead angle of illumination, operator can open LED fast, finishing the work of high-effect high-quality, does not need to reconfigure lighting apparatus, save the consumptive material of work, improve operating efficiency.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
