4- change-over switches, 4a- toggles protrusion, 4b- stir pin, 5- manual knobs, 5a- rotation axis, 5b- rotation process handles.
Specific embodiment
Figures 1 and 2 show that a preferred embodiment of this gear adjusting device of the application, with application No. is
201710465435.7 Chinese invention patent application it is identical, which is also for adjusting multifunctional motor-driven
The gear of hammer drill makes the electric hammer drill be selectively in hammer gear, bore gear or hammer drill gear.Certainly, which is adjusted
Device can be used for adjusting the gear of other electric tools, to realize the conversion of meeting between other operating modes.
This gear adjusting device of the present embodiment mainly includes：Housing 1, spring 3, manual knob 5, change-over switch 2 and toggle
4.Wherein：
Housing 1 forms the elastic element accommodating cavity 1a of circular ring shape and in aforementioned circular ring shape elastic element accommodating cavity
The pivoting hole 1b of (i.e. the circle centre position of circular ring shape) at the heart, and pivoting hole 1b is circular hole.
Spring 3 is configured in above-mentioned elastic element accommodating cavity 1a, and along the circumference of the circular ring shape elastic element accommodating cavity
The rounded bending in direction.
Manual knob 5 includes the rotation process handle 5b that is an integral structure and rotation axis 5a, wherein rotation process handle 5b
So that user is manually operated outside housing 1, rotation axis 5a is penetrated in above-mentioned pivoting hole 1b and can be around pivoting hole 1b hole axle
Line pivotal movement.
Change-over switch 2 is sheathed on rotation axis 5a and circumferentially fixed with rotation axis 5a.Specifically, change-over switch 2 and rotation axis
5a is split structure, and the two is connected by spline, and when rotation axis 5a is rotated, rotation axis 5a is rotated therewith.Certainly, we
Change-over switch 2 and rotation axis 5a can be made of one structure, but change-over switch 2, manual knob 5 and housing 1 will be increased in this way
Triangular assembly difficulty.And change-over switch 2 is integrally formed with stretching into elastic element accommodating cavity 1a and be resiliently clamped in bullet
Change-over switch protrusion 2a between 3 both ends of spring, that is to say, that the length both ends of spring 3 are born against change-over switch protrusion 2a's
Change-over switch protrusion 2a is clamped in both sides.
4 rotary sleeve of toggle is set on rotation axis 5a, and toggle 4 is also integrally formed with stretching into elastic element accommodating cavity 1a
In and the toggle protrusion 4a that is resiliently clamped between 3 both ends of spring, that is to say, that the length both ends of spring 3 are simultaneously
It bears against and is clamped in the both sides of toggle protrusion 4a, by toggle protrusion 4a.Formed on toggle 4 for directly stir gear from
Stir pin 4b in clutch outer ring.
In order to facilitate the operation principle of the description present apparatus, the length both ends of spring are now referred to as first end and second
End.When needing to convert the gear of hammer drill, it is assumed that user rotates clockwise manual knob 5, and manual knob 5 drives change-over switch 2
Rotate synchronously, the change-over switch protrusion 2a on change-over switch 2 will make along the first end along direction mortgage spring 3 spring shorten (because
Change-over switch protrusion 2a compresses the first end clockwise movement of spring, Gu and so that spring first end leaves toggle protrusion 4a, spring
Second end leave change button protrusion 2a).Change-over switch protrusion 2a can be transferred to the power that spring first end applies by spring body
Spring second end, then pass to toggle protrusion 4a by spring second end makes toggle protrusion 4a suitable by the spring second end time
Conterclockwise thrust, so that toggle 4 is also along rotation, stirring pin 4b and can stir gear thereon after toggle 4 rotates
The conversion of hammer drill gear is completed in the outer ring of conversion clutch.After unclamping manual knob 5, under spring force, change-over switch protrusion
Return a small distance that 2a is counterclockwise (the pin 4b that stirs on toggle is loaded with clutch), change-over switch protrusion 2a and toggle protrusion
4a is clipped in again between both ends of the spring portion, but change-over switch protrusion 2a and toggle protrusion 4a is in elastic element accommodating cavity 1a at this time
In position changed.
Similarly, if user rotates counterclockwise manual knob 5, toggle 4 will counterclockwise turn under the effect of 3 elastic force of spring
Dynamic, similary clawback moves the outer ring of gear conversion clutch, completes the conversion of hammer drill gear.
Because change-over switch 2 is to transmit by single arc spring 3 to the power that toggle 4 applies, user is not only optimized
To the rotation feel of manual knob 5, and toggle 4 can be avoided, change button 2 and twisting resistance that manual knob 5 is subject to is excessive and produce
Structural failure is given birth to, while after the rotary force being subject in release manual knob 5, toggle 4 understands again Automatic-clamping in spring with button 2 is changed
Between both ends, it is ready for the adjusting of gear next time.
The movement of change-over switch protrusion 2a and the movement of toggle protrusion 4a interfere in order to prevent, above-mentioned in the present embodiment
Change-over switch protrusion 2a and toggle protrusion 4a arc-shaped elastic element accommodating cavity 1a in the radial direction one in one outside arrange.Specifically
Ground, in circular ring shape elastic element accommodating cavity 1a in the radial direction, change-over switch protrusion 2a is arranged in the inside of toggle protrusion 4a, such as
Fig. 2.
It should be noted that above-mentioned spring 3 can also use the elastic element of other structures form to substitute, such as function phase
As torsional spring.
Certainly, above-described embodiment is only the technical concepts and features for illustrating the application, and its object is to make people much of that
Solution present context is simultaneously implemented according to this, and the protection domain of the application can not be limited with this.It is all according to the application major technique
The equivalent transformation or modification that the Spirit Essence of scheme is done, should all cover within the protection domain of the application.
