Abstract
A kind of power tool with additional header is the utility model is related to, belongs to power tools technology field.The instrument includes the main frame that rotary drive output can insert additional header, the main frame rotary drive output installation is with locked and tends to the button of latched position, the button has grab adjacent to the side of output end, and the inserting end of the additional header has the neck to match with the grab；When the push-button reset is in the locked position, the grab enters the position for constraining the neck；When the button, which is pressurized, to be in the unlocked position, the grab departs from the position for constraining the neck.Button snap hook-type locking mechanism of the present utility model not only locks reliable, assembling and easily, and is easy to manipulate.
Description
Technical field
A kind of instrument adapter is the utility model is related to, especially a kind of power tool with additional header, belongs to power work
Has technical field.
Background technology
One of the most frequently used electric tool of hand held electric drill.In order to be able to increase deceleration, steering, torsion on the original basis
The functions such as regulation, so as to expand its scope of application, notification number be EP2101959B1 European patent discloses a kind of termination is attached
Part, including for input inserted terminal, the lock cell with the constraint connection of power tool power output head, and and tool heads（Example
Such as drill bit）Constrain the output inserted terminal of connection, the input transmission mechanism of the inserted terminal by therein（Such as moment of torsion regulation
Mechanism）With output inserted terminal drive connection, lock cell therein includes an annulus spring for being used as locking connection, the annulus
The first end of spring is placed in the fixed position of matrix one of lock cell, and the second end is positioned to that list can be locked relatively in circumferencial direction
First substrate motion.Lock cell therein is complicated, assembling is inconvenient, manufacturing cost is higher.
The content of the invention
The purpose of this utility model is：The shortcomings that existing for above-mentioned prior art, propose a kind of additional header assembly and disassembly lock
Determine the simple and reliable power tool with additional header of mechanism.
In order to reach object above, power tool basic structure of the utility model with additional header is：Including rotary power
Output end can insert the main frame of additional header, the main frame rotary drive output installation with locked and
Tend to the button of latched position, the button has a grab adjacent to the side of output end, the inserting end of the additional header have with
The neck that the grab matches；When the push-button reset is in the locked position, the grab enters the position for constraining the neck
Put；When the button, which is pressurized, to be in the unlocked position, the grab departs from the position for constraining the neck.
Compared with prior art, button snap hook-type locking mechanism of the present utility model not only locks reliable, assembling easily, and
And it is easy to manipulate.
Further, installation has locking bit respectively on the shell of the both sides butted structure of the main frame rotary drive output
The button with unlocked position is put, the button is built with spring.
Further, have in the button and pacify spring-loaded bullport.
Further, the grab and neck has chamfering respectively to spigot.
Brief description of the drawings
The utility model is further described below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is that Fig. 1 inserts the cross section structure diagram after additional header.
Fig. 3 is the dimensional decomposition structure diagram of Fig. 1 embodiment main frames.
Embodiment
Embodiment one
Power tool of the present embodiment with additional header is a kind of hand held electric drill, and its structure is as shown in Figure 1, Figure 2, Figure 3 shows, electric
The additional header 4 with moment of torsion regulatory function can be inserted on demand by boring the rotary drive output of main frame 1.The rotary power of main frame 1 is defeated
Go out and the button 2 with locked is installed respectively on the shell 1-1 of the both sides butted structure at end, in the button 2
Bullport in spring 5 is housed, therefore tend to overhanging latched position.3 be trim in figure.Button 2 adjacent to output end one
Side has grab 2-1, and the inserting end of additional header 4 has the neck 4-1 to match with grab 2-1.Grab 2-1 and neck 4-1 pair
Spigot has chamfering respectively, therefore inserts very convenient.
When pulling down trim 3, after additional header 4 to be inserted into the clutch end of main frame 1, as shown in Fig. 2 button 2 is in bullet
Under the reset response of spring 5, neck 4-1 latched position is caught in grab 2-1, so as to constrain additional header, it is connected with main frame
It is integrated, realizes required additional function.When not needing additional header 4 to be, as long as two buttons 2 are simultaneously radially compressed to overcome spring 5
Active force when, grab 2-1 is the position for departing from constraint neck 4-1, so as to as shown in figure 1, easily additional header 4 can be taken out
Go out.
It is demonstrated experimentally that the structure of the present embodiment is reliable, easy to operate, ergonomics are good, and manufacturing cost economy.Except upper
State outside embodiment, the utility model there can also be other embodiment.All technologies formed using equivalent substitution or equivalent transformation
Scheme, all fall within the protection domain of the requires of the utility model.
Claims (4)
1. a kind of power tool with additional header, including rotary drive output can insert the main frame of additional header, its feature exists
In：The main frame rotary drive output installation is with locked and tends to the button of latched position, described
Button has grab adjacent to the side of output end, and the inserting end of the additional header has the neck to match with the grab；Work as institute
When stating push-button reset and being in the locked position, the grab enters the position for constraining the neck；When the button is pressurized in solution
