Detailed description of the invention
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
Reciprocating sow in the present embodiment, it includes casing 11, the ring flange 13 being fixed in casing 11, the motor 12 being arranged on ring flange 13, can be rotatably mounted in casing 11 around its central axis and movement housing 7, the gear wheel 14 being arranged between ring flange 13 and movement housing 7 that the central shaft of central shaft and ring flange 13 coincides, be arranged on movement housing 7 and driven reciprocating reciprocating lever 1, the battery bag 10 driving motor 12 to rotate by motor 12 and control the switch 9 that motor 12 starts and cuts out.The end of reciprocating lever 1 connects chuck 2, is used for connecting saw blade.
Movement housing 7 is freely up and down spent by casing 11 is spacing, but can rotate relative to casing 11.The stopping means limiting movement housing 7 position relative with casing 11 it is provided with in movement housing 7.
Stopping means includes the hole, multiple location 18 being arranged in casing 11, be movably disposed on movement housing 7 and can movement housing 7 shrinks relatively spline pin 8, spline pin 8 and location hole 18 grafting separatably.Rotating disk 5 can rotate relative to movement housing 7.
Stopping means also include rotating be arranged on movement housing 7 in and offer rotating spanner 4 that the rotating disk 5 of gathering sill 17 is connected with rotating disk 5, be arranged on gathering sill 17 in and the connector 19 that can move along gathering sill 17 lengthwise bearing of trend, one end of spline pin 8 is by being connected with connector 19, the other end of spline pin 8 is through movement housing 7 and location hole 18 grafting separatably, and gathering sill 17 moves closer to the central shaft of rotating disk 5 from its one end to the other end.Gathering sill 17 is curved.The central shaft of rotating disk 5 coincides with the central shaft of movement housing 7.When connector 19 is positioned at one end of gathering sill 17, spline pin 8 plugs with hole 18, location, and when connector 19 is positioned at the other end of gathering sill 17, spline pin 8 is separated with hole 18, location.
When pulling rotating spanner 4, rotating disk 5 rotates towards from gathering sill 17 one end to the direction of gathering sill 17 other end.Be additionally provided with in movement housing 7 rotating disk 5 is applied power make its towards from gathering sill 17 other end to the direction of gathering sill 17 one end rotate torsion spring 6.
Being provided with locking plate 16 in casing 11, hole 18, location is i.e. opened on locking plate 16.Locking plate 16 and casing 11 are interference fit, are in stationary state.
Reciprocating lever 1 in the present embodiment has two operating positions, as shown in Figure 3 with shown in accompanying drawing 4.As shown in accompanying drawing 3 and accompanying drawing 5, reciprocating lever 1 is positioned at the first operating position, and spline pin 8 plugs with hole 18, corresponding location, and movement housing 7 is relatively fixed with casing 11, the most rotatably；When pulling rotating spanner 4, rotating spanner 4 drives rotating disk 5 to rotate, under the effect of gathering sill 17, connector 19 moves to the other end from one end of gathering sill 17, the relative movement housing 7 of spline pin 8 shrinks and exits hole 18, location, and as shown in Figure 6, at this moment movement housing 7 is in rotatable state；Movement housing 7 is rotated to an angle (for half-twist in the present embodiment, reciprocating lever 1 to the second operating position) time, spline pin 8 moves at the hole, location 18 of correspondence, and rotating disk 5 can be owing to rotating under the effect of torsion spring 6, under the effect of gathering sill 17 and connector 19, spline pin 8 is made to insert in the corresponding hole, location 18 of locking plate 16, at this moment movement housing 7 is in locking state, is relatively fixed with casing 11, as shown in accompanying drawing 4 and accompanying drawing 7, now, reciprocating lever is in the second operating position.
Realize the rotation of reciprocating lever 1 by relatively rotating of movement housing 7 and casing 11, determine the operating position of reciprocating lever 1 according to the number in hole 18, location and spread configuration.
