Problems solved by technology

[0002] Most of the multifunctional saws on the market now use pressure plates and hexagon socket screws. The replacement operation of the multifunctional saw blades is either fastened or loosened with special tools, or directly rotated by hand to rotate the fastening ring. Functional saw structure and replacement method, because there is no locking safety structure, it is easy to loosen during the rotation of the saw blade, which brings hidden dangers to safe use, and the fastening or dismounting operation is troublesome, sometimes it cannot be fastened, and sometimes it cannot be disassembled
At the same time, it also needs to be equipped with a hexagonal wrench, which needs to be carried at any time, and has defects such as easy loss

Abstract

The invention relates to a quick changing structure for a multifunctional saw, solves the problem that replacing of a saw blade of a traditional multifunctional saw is tedious, and belongs to the technical field of mechanical equipment. The quick changing device comprises a quick changing wrench buckle, an eccentric block, a movable rod, a spring collet, a swelling rod and a compression spring. The quick changing wrench buckle and the eccentric block are connected with the top of a head shell through a cylindrical pin. The movable rod is arranged inside an output shaft, the top of the movable rod is connected with the eccentric block in an abutting mode, and the bottom of the movable rod is in threaded connection with the swelling rod. The outer side of the swelling rod is sleeved with the spring collet. The outer side of the spring collet is sleeved with the compression spring. A knife rest is arranged at the bottom of the output shaft. The inner wall of the knife rest is provided with an inward gradient from top to bottom, and a protruding block is arranged in the position, corresponding to the gradient, of the outer surface of the spring collet. According to the quick changing structure for the multifunctional saw, the diameter of the spring collet can be changed only by poking the quick changing wrench buckle, and thus the purposes of disassembling and replacing a saw blade are achieved. The invention further discloses a quick changing method of the quick changing structure for the multifunctional saw.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and relates to a detachable structure for quickly separating or loading a working head of a head-changing electric tool from a machine body, and in particular to a multi-functional saw quick-change structure.
