Abstract
The invention provides an electric screw driver. The electric screw driver comprises an LED lamp and a press type power switch; a screw driver head and the LED lamp are fixed to the same end of a shell; the power switch comprises a button arranged inside the shell and a button cap penetrating through the shell; the button cap comprises a cap body penetrating through the shell, a sealing convex edge arranged in the middle of the outer periphery surface of the cap body in a surrounding mode and a button column arranged inside the cap body and connected to the cap body; when the button cap is pressed, the button column is connected to the button in an abutting mode, and a motor and the LED lamp are electrified; the button cap further comprises a pressing plate arranged on the cap body in a sleeving mode; connectors are arranged on the periphery of the pressing plate, and the pressing plate, the sealing convex edge and the shell arranged in order are closely connected through the connectors. Compared with the prior art, by arranging the LED lamp, the electric screw driver still can be used in the environment with poor light; the press type power switch with good sealing performance is adopted, and therefore dust is prevented from entering the shell and the failure rate of internal components is greatly lowered.
Description
Technical field
The present invention relates to motor machine technical field, especially relate to a kind of electric screw driver.
Background technology
Along with the development of science and technology, screwdriver is also gradually replaced by electronic rotation from artificial rotation.The generation of electric screw driver, for people
Saved substantial amounts of time and efforts.Owing to electronic product miniaturization is the most universal, carry out at the electronic product little to volume
When tissue or dismounting, especially in the environment of light is bad, the position relationship between cutter head and the screw of electric screw driver is difficult to
Hold, often can make mistakes.
The internal structure of electric screw driver is complicated, finely, owing to being provided with multiple switch on shell, if sealing effectiveness is bad
If, dust can be made to enter in shell, motor or other devices are caused damage.In push switch, it usually needs opening
Setting up button cap on the button closed, button is located in the shell of switch, and button cap then enters shell, pressing through this housing portion
Button cap can touch described button.On the one hand button cap can improve by the comfort level of finger when compressing switch, and on the other hand can lead to
Cross button cap and seal this shell, prevent dust or water from entering in the circuit being connected with described button, thus there is protective effect.
Button cap uses the elastomeric material of elasticity to make mostly, and available elastic fit is in case surface, but himself elastic provides
Gluing, sealing effect is limited, and after long-time use, the performance of deformation and reply reduces, and causes sealing property to be deteriorated.
Summary of the invention
The invention aims to solve the inapplicable dark of electric screw driver and poor the lacking of switch seal in prior art
Fall into, it is provided that a kind of electric screw driver solves the problems referred to above.
To achieve these goals, technical scheme is as follows:

Described on and off switch includes being located at the button in described shell and the button cap through described shell；Described button cap includes
Through described shell cap body, be located on the sealed convex edge in the middle part of cap body outer peripheral face and be located at the internal button being connected with cap body of cap body
Post；Described button cap when being pressed described button post abut with described button, make described motor and described LED be energized；Described
Button cap also includes the pressing plate being set in described cap body；Described pressing plate periphery be provided with connector by order arrange described pressing plate,
Sealed convex edge and shell compact siro spinning technology.
Preferably, described pressing plate is consistent with the profile of sealed convex edge.
Preferably, described pressing plate is made up of hard material, and the most square, prismatic, circle or rectangle.
Preferably, described pressing plate, the periphery of sealed convex edge and shell are correspondingly provided with screw.
Preferably, described pressing plate is made up of hard material.
Preferably, the sidewall of described shell is further fixed on LED switch；Described LED switch connects described LED respectively by wire
Lamp and described on and off switch, in order to control the break-make of LED and power supply.
The present invention compared with prior art, has the advantages that
1. the same one end with screwdriver bit being provided with LED, when needed, open LED switch, can make LED is work
Making to provide illumination, and direction of illumination is accurate, it is to avoid the many errors in work；
2., owing to have employed pressing plate, sealed convex edge can be closely attached to corresponding switch component (shell) surface, make button cap preferably
Enclosed switch, even if the sealed convex edge of inside is aging, close at pressing plate also can keep good sealing effectiveness by pressure.This
Strengthening due to the outer rim of sealed convex edge outward, pressing plate can be fitted the most in relatively large area, strengthens sealing effectiveness.

Fig. 2 is the structural representation of pressing type power source switch；
Fig. 3 is the axonometric chart of push switch.
Detailed description of the invention
By making the architectural feature to the present invention and effect of being reached have a better understanding and awareness, in order to preferred embodiment
And accompanying drawing coordinates detailed description, it is described as follows:
As shown in Figure 1 and Figure 2, a kind of electric screw driver, including shell 50, screwdriver bit 60, motor, LED 70, just
Reversal switch 80, pressing type power source switch 90.
Screwdriver bit 60 and LED 70 are fixed on same one end of shell 50；Motor is fixed on (not shown) in shell 50；
Driven by motor screwdriver bit 60 rotates；On and off switch 90 is fixed on the other end of shell 50；On and off switch 90 is by motor, LED
Lamp 70 connects with external power respectively；Forward-reverse switch 80 is fixed on the sidewall of shell 50.
On and off switch 90 includes the button (not shown) being located in shell 50 and the button cap passing shell 50；Button
Cap includes the cap body 10 through shell 50, is located on the sealed convex edge 20 in the middle part of cap body 10 outer peripheral face and is located at cap body 10 inside
The button post 30 being connected with cap body 10；When button cap is pressed, button post 30 abuts with button, makes motor and LED 70 points
