Problems solved by technology

However, the two saw blades of this hand-held electric slotting cutting machine are fixed on the drive shaft, so the usability is relatively simple, the saw blades are difficult to disassemble, and the work efficiency cannot be significantly improved.
In daily work, the existing double saw blades can no longer meet the needs of the work
Moreover, during the use of the ordinary double saw blade cutting machine, due to the needs of the operation, the distance between the saw blades must be constantly changed, so the cumbersome measurement work also brings a lot of inconvenience to the constructor.

Abstract

The invention relates to an improved handheld electric grooving cutting machine, which comprises a machine body and a machine head. The machine head is provided with three saw blades; a first saw blade is fixed on a transmission shaft; the end of the transmission shaft is fixed with a detachable lengthened transmission shaft; a plurality of distance sleeves are sleeved on the lengthened transmission shaft; a second saw blade is fixed in the middle of the lengthened transmission shaft; a third saw blade is fixed at the end of the lengthened transmission shaft; the top of the machine head is also provided with a transparent dustproof cover marked with scales; and two scale chutes are formed above the scales of the dustproof cover corresponding to the saw blades, and two measuring cards capable of freely moving in the scale chutes left and right are arranged. The improved handheld electric grooving cutting machine has the advantages of wide application range, convenience of operation, high efficiency and multiple functions.

Description

technical field [0001] The invention relates to a device for slotting and cutting, in particular to a hand-held electric slotting and cutting machine with wide application range, high efficiency and multiple functions. Background technique [0002] Most of the saw blades of the existing hand-held electric slotting and cutting machines are monolithic, the work efficiency is low, and the slotting width does not have random flexibility. Recently, a hand-held electric slotting and cutting machine with double saw blades has appeared. For example, the Chinese invention patent application publication CN201092094Y discloses such a hand-held electric slotting and cutting machine. But the two saw blades of this hand-held electric slotting cutting machine are fixed on the transmission shaft, so the usability is relatively simple, the saw blades are difficult to disassemble, and the work efficiency cannot be significantly improved. Existing double saw blades can't meet the needs of wor...
