Description

Hand operated plane

The present invention relates to the described a kind of hand operated plane of claim 1.

European patent EP 563 350 discloses a kind of like this hand operated plane, and near the chip area side direction the bits of this planer roll from a plane is discharged to the left or to the right.Chip removal is undertaken by air blast.Air-flow is guided to the shavings outlet that two respective side of shell are provided with from the planer enclosure.Alternately open with the vertically disposed shavings outlet of hand operated plane direction of feed, thereby discharge shavings towards a side or opposite side.

Regulate the conversion of chip removal by a Tube-like valve around its rotation to a side or opposite side.Valve is separated the conversion of carrying out the chip removal direction by a dividing plate that extends in this valve internal fore-and-aft tilt.

This planer has the shell of a jar shape, and stretch out from this shell at the pipe type valve two ends.

It is convenient and reliably that this planer chip removal is transformed into one or another direction.If but on the side faces at both ends of the valve that stretches out shell, connected a dust exhaust apparatus, undesirable change of chip removal direction then could not be avoided.Because the pipe joint of dust catcher is inserted on the end of valve, in the shavings process, this valve may rotate, thereby cause the out of contior change of chip removal direction, so chip removal may be carried out to both sides simultaneously, or carry out to a side that on valve barrel, does not connect the sweep-up pipe joint, shavings just undesirably enters in the atmosphere like this.

In contrast, the two ends that hand operated plane of the present invention has claim 1 a described feature, particularly valve do not have protruding, thereby have the advantage that can connect dust exhaust apparatus on valve, and valve barrel undesired rotation can not occur.So just avoided chip removal to enter the danger of the opposite way round.In addition, this solution also can make valve lack some with light.

Because shell or side cover have the pipe joint that is straight line with valve, so the connector of outside dust exhaust apparatus can carry out antitorque fixing, and can realize effective dust suction.

Because shell is connected with pipe joint antitorquely, particularly whole the connection is so the shell of hand operated plane is firm especially.

Because shell has the adjusting rod that a radial slot is regulated break-through in the scope of at least one pipe joint, so that the valve rotation, so the chip removal direction helps regulating with handle.

Since the two ends of the groove in pipe joint scope limit the adjustment stroke of adjusting rod-as backstop with-and therefore limit the rotating distance of valve, so can realize the reliable adjustment of chip removal direction.

Because the pipe joint adjacent with the two ends of valve constitutes axial stop and sealing surface, so valve seals especially to shell, so just improved chip removal efficient.

Owing to the adjusting rod of valve rotation can be sandwiched in this valve,, and is convenient to install so the structure of valve is simple especially.
