Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1-3, the best embodiment of the present invention is a lithium electric drill, which comprises a housing 1, wherein a shifting knob 2 is provided on the side of the housing 1, and a window 11 for accommodating the shifting knob 2 is provided on the side of the housing 1. Be provided with coaxial setting's driving lever circle 3 in the casing 1, gear box 4 and change retaining ring 5, shift and dial the outer lane fixed connection who turns round 2 and driving lever circle 3, it installs in gear box 4's periphery to change retaining ring 5 suit, gear box 4 appearance is roughly the column, it passes through sharp guiding mechanism interconnect to shift ring 5 and gear box 4, make and trade retaining ring 5 can only be relative gear box 4 back-and-forth movement (the axial direction who trades retaining ring 5 is the fore-and-aft direction) under the external drive, a plurality of sharp guide way 41 of the circumference equipartition of the fore-and-aft direction of outside setting and a plurality of stop block 51 of the circumference equipartition of retaining ring 5 inner circle are traded to sharp guiding mechanism, stop block 51 and the sliding. The shifting ring 5 and the shifting rod ring 3 are in transmission connection through a plane cam structure, so that the shifting rod ring 3 can rotate to push the shifting ring 5 to move back and forth. The plane cam structure comprises a wedge-shaped convex block 31 on the front end face of the driving lever ring 3 and a wedge-shaped groove 52 on the rear end face of the gear shifting ring 5, wherein one side of two side faces of the wedge-shaped convex block 31 is of an inclined plane structure, the other side of the two side faces of the wedge-shaped convex block 31 is of a plane structure (the plane structure is parallel to the axial direction of the gear shifting ring 5), and the wedge-shaped convex block 31 and the wedge-shaped.
When the shifting knob 2 is turned downwards, the shifting knob 3 is driven to rotate anticlockwise, the shifting knob 3 and the shifting collar 5 are mutually matched and connected through the wedge-shaped bump 31 and the wedge-shaped groove 52, when the shifting knob 2 is turned downwards, the shifting collar 5 is limited by the linear guide mechanism to be incapable of rotating and only capable of moving back and forth, so that the wedge-shaped bump 31 and the wedge-shaped groove 52 are extruded at the inclined plane structure, the shifting collar 5 is forced to move forwards, the shifting collar 5 drives the mechanism in the gear box 4 to realize shifting, when the shifting knob 2 is turned upwards, the shifting collar 3 is driven to rotate clockwise, the shifting collar 3 and the shifting collar 5 are mutually matched and connected through the wedge-shaped bump 31 and the wedge-shaped groove 52, when the shifting collar 3 rotates clockwise, the shifting collar 5 is limited by the linear guide mechanism to be incapable of rotating, and the shifting mechanism can only move back and forth, so that the plane structures of the wedge-shaped convex blocks 31 and the wedge-shaped grooves 52 are extruded, the shifting collar 5 is forced to move back, and the shifting collar 5 drives the mechanism in the gear box 4 to realize gear shifting.
The utility model discloses a lithium electric drill shifts to dial traditional setting at the casing top and turns round 2 settings on one's body at the side of casing 1, shifts to dial and turns round 2 the top that is located the portion of gripping of casing 1, shifts to dial and turns round 2 more closely apart from the portion of gripping of casing 1, and the operating personnel one-hand of being convenient for carries out the gear switching, and convenient and fast improves work efficiency.
