Both ends be connected respectively with the two sides of fixed frame 620, shifting block 630 is set in guide pins 632.
In specific implementation, trundle 640 include the first cylinder, the second cylinder and third cylinder, the second cylinder and
Both ends of the end of third cylinder respectively with the first cylinder are vertically connected, the second cylinder and third cartridges parallel, and the second cylinder
It is located at the two sides of perpendicular where the first column axis with third cylinder, the second cylinder passes through first through hole 651 and the
Two through-holes 621 are simultaneously connected with shifting block 630, and knob 610 is equipped with fourth hole 611, and third cylinder is configured as insertion four-way
Hole 611 is arranged.
Optionally, the first transmission component 200 includes Oscillating lever bearing 220 and beat bearing 230, and beat bearing 230 is set in
In rotary shaft 700, when clutch tooth 400 does traversing reciprocating action along rotary shaft 700, beat bearing 230 and clutch tooth 400 are clamped
Or separation.Furthermore, the end adjacent with clutch tooth 400 of beat bearing 230 is equipped with the first scallop 231, the first tooth
Shape hole 231 is matched according to the tooth form of clutch tooth 400 to be arranged, in order to be clamped with clutch tooth 400.
When beat bearing 230 and clutch tooth 400 are clamped, since rotary shaft 700 drives clutch tooth 400 to rotate, thus nibble
Closing tooth 300 can drive beat bearing 230 to rotate, so that 220 forced belt piston 120 of Oscillating lever bearing is rushed in cylinder 110
Movement is hit, i.e. piston 120 does traversing reciprocating action in cylinder 110；When beat bearing 230 is separated with the second clutch component 400
When, Oscillating lever bearing 220 does not stress, and piston 120 is failure to actuate.
In specific implementation, Oscillating lever bearing 220 includes swing rod 221 and wobble ring 222, one end of swing rod 221 and wobble ring
222 are connected, and the other end and piston 120 of swing rod 221 are rotatablely connected, and the peripheral side of beat bearing 230 is drawn equipped with what is be obliquely installed

232 place plane of guiding groove and the side of beat bearing 230 are in a certain angle.
Second transmission component 500 includes active umbrella tooth 510 and driven umbrella tooth 520, and driven umbrella tooth 520 is set to rotary shaft
700 one end, 520 engaged transmission of active umbrella tooth 510 and driven umbrella tooth.In the present embodiment, active umbrella tooth 510 and driven umbrella tooth
520 form gear pair to drive rotary shaft 700 to do axial-rotation movement.
In one possible implementation, knob assembly 600 drives clutch tooth 400 to slide axially along rotary shaft 700, with
Engage clutch tooth 400 with engaging tooth 300, clutch tooth 400 is clamped or separates with the first transmission component 200.
When clutch tooth 400 is separated with beat bearing 230, i.e., when knob 600 rotates for the first time, clutch tooth 400 is along rotation
Shaft 700 is slided to 300 direction of engaging tooth, and clutch tooth 400 is engaged with engaging tooth 300, at this time beat bearing 230 and clutch tooth
400 separation, Oscillating lever bearing 220 do not stress, and piston 120 is failure to actuate not do percussion action in cylinder 110, and clutch tooth 400 is logical
Crossing engaging tooth 300 drives cylinder 110 to do spinning movement, is bored when electric hammer output without impacting with realizing, i.e., electric hammer, which is in, bores shape
State.
When clutch tooth 400 and beat bearing 230 are clamped, i.e., when second of the rotation of knob 610, clutch tooth 400 with nibble
It closes tooth 300 to engage, clutch tooth 400 is slided along rotary shaft 700 to 300 opposite direction of engaging tooth at this time, beat bearing 230 and clutch tooth
400 clampings, 220 forced belt piston 120 of Oscillating lever bearing do reciprocating action to generate impact in cylinder 110, and clutch tooth 400 is logical
Crossing engaging tooth 300 drives cylinder 110 to do spinning movement, bores and impacts when electric hammer output to realize, i.e., electric hammer, which is in, bores hammer shape
State.
In alternatively possible implementation, knob assembly 600 drives clutch tooth 400 to slide axially along rotary shaft 700,
So that clutch tooth 400 is separated with engaging tooth 300, clutch tooth 400 and the first transmission component 200 are clamped, tooth form end 631 and engaging tooth
300 clampings or separation.
When tooth form end 631 is separated with engaging tooth 300, i.e., when knob 610 rotates for the third time, clutch tooth 400 continues edge
Rotary shaft 700 is slided to 300 opposite direction of engaging tooth, and clutch tooth 400 is separated with engaging tooth 300, beat bearing 230 and clutch tooth
400 clamping, 220 forced belt piston 120 of Oscillating lever bearing do reciprocating action in cylinder 110 generate impact, at this time due to from
It closes tooth 400 and engaging tooth 300 separates, engaging tooth 300 does not stress, therefore 110 radial direction of cylinder does not stress, which can export
End adjusts angle, i.e. the electric hammer is in angular adjustment state.
When tooth form end 631 is engaged with engaging tooth 300, i.e., when the 4th rotation of knob 610, clutch tooth 400 is along rotation
Axis 700 is slided to 300 direction of engaging tooth, and clutch tooth 400 and engaging tooth 300 are still in discrete state at this time, but the tooth of shifting block 630
Shape end 631 is engaged with engaging tooth 300, and cylinder 110 can not do radial rotary, and beat bearing 230 and clutch tooth 400 are clamped, swing rod
220 forced belt piston 120 of bearing does percussion action in cylinder 110, impacts the electric hammer only when exporting, i.e., electric hammer is in
Hammer working condition into shape.
In actual design process, rotation for the first time, second of rotation, third time rotation, the 4th rotation and rotation
The motion state of corresponding component successively realizes that brill, brill hammer, angular adjustment, the matching of four kinds of working conditions of hammer are set all in accordance with electric hammer afterwards
It sets, when the corresponding working condition realized of rotation changes, the manner of execution of corresponding component also corresponding change therewith,
This is not further qualified in the application.
In the present embodiment, each rotation angle of knob 610 can be 30 °；Alternatively, the rotation angle that knob 610 is each
Degree can be 45 °；Alternatively, each rotation angle of knob 610 can be 60 °；Alternatively, each rotation angle of knob 610 can
Think 90 °.In actual design process, the rotation angle of knob 610 can or operator determining according to actual design demand
Comforts of use determine, in addition, the functional type of the number of revolutions of knob 610 realization according to needed for electric hammer is arranged, the application
In this is not limited further.
In conclusion the method provided by the embodiments of the present application for realizing four kinds of functions, by turning knob component to drive
Clutch tooth does traversing reciprocating action along rotary shaft, so that clutch tooth be driven tooth engagement or to separate with engagement, then passes through the second transmission
Component drives rotary shaft spinning movement to drive clutch tooth rotation, to drive engaging tooth and rotational cylinder or not rotate, drive from
It closes tooth and is clamped or separates whether band piston clump moves back and forth in cylinder to drive the first transmission component with the first transmission component
Interior generation impact, and drive knob assembly and engagement tooth engagement or separate, consequently facilitating adjusting cylinder rotation or limiting cylinder
Rotation is easy to implement electric hammer drill, hammer drill, angular adjustment and the conversion for hammering four kinds of working conditions into shape, and easy to operate.
