Description
Technical field
The utility model relates to a kind of tool rest rotating mechanism of portable cutters.
Background technology
Multiple portable, portable cutters is arranged at present, have on the cutting machine body one can ccontaining tool rest cavity, tool rest stretches into behind the cavity fixing, and blade is installed on the tool rest, blade has only a position like this, needs the whole cutting machine of rotation could change the angle of blade.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of tool rest rotating mechanism of portable cutters, thereby can make tool rest rotate the angle that changes blade easily, can fixedly secure tool rest.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: the tool rest rotating mechanism that a kind of portable cutters is provided, it comprise on a tool rest and the cutting machine body can ccontaining this tool rest cavity, it is characterized in that: described tool rest has a column part that can stretch into described cavity, the locating slot that has at least one to extend to the column part axis on the circumference of this column part; One brake shoe is installed in described cavity, and an end of brake shoe is fixed on the cutting machine body, and the brake shoe other end is a free end, connects a crank near the brake shoe free end shaft on the cutting machine body, can press to the brake shoe free end when crank rotates; At the locating piece that described cavity place also has a shape and locating slot to adapt, this locating piece radially slides along column part.
Further improvement in the technical proposal is:
Four locating slots are arranged on the described column part.
Described locating slot is a rectangle.
Described locating slot is circular.
One chute for the locating piece slip is set on the cutting machine body, a spring is installed above the locating piece.
The beneficial effects of the utility model are: because the tool rest rotating mechanism of portable cutters of the present utility model has a column part on tool rest, locating slot is set on the column part, corresponding locating piece is set on the cutting machine body, rotating tool rest makes locating piece stretch into locating slot, can change the angle of blade, have on the cutting machine body and the corresponding brake shoe of tool rest column part, contact area is big, therefore installs firmly.
