Detailed Description

As shown in fig. 1-2, a novel split sprocket comprises a rotating member 100 which is matched with a shaft of an angle grinder to rotate synchronously and a matching member 200 which is assembled with the rotating member 100 to rotate synchronously, wherein the rotating member 100 is provided with an assembling hole 110 which is assembled with a clamping block on the shaft of the angle grinder, the rotating member 100 is assembled with the clamping block on the shaft of the angle grinder and rotates synchronously with the shaft, the matching member 200 is provided with a through hole 210 for the shaft of the angle grinder to pass through, the matching member 200 is provided with a gear tooth 220 for driving a chain of an electric saw to rotate, the rotating member 100 is fixedly assembled with the matching member 200 in a clamping manner, the sprocket is arranged in a split structure, when the angle grinder is modified into the electric chain saw, the sprocket is arranged on an output shaft of the angle grinder so as to drive the chain of the electric chain saw to rotate, the advantage of the split structure is, also be convenient for product production and processing, traditional integral type structure punches a hole complicacy.

The rotating member 100 is provided with a plurality of clamping holes 120 which are arranged at equal intervals, correspondingly, the matching member 200 is provided with clamping blocks 230 which are consistent with the clamping holes 120 in number, the matching member 200 is clamped and connected in the clamping holes 120 of the rotating member 100 through the clamping blocks 230, clamping and linkage are realized through the matching of the clamping blocks 230 and the clamping holes 120, the structure is simple, the assembly is convenient, and the difference value between the clamping holes 120 and the clamping blocks 230 is less than 1mm +/-0.1 mm.

The rotating member 100 has three clamping holes 120, correspondingly, the clamping blocks 230 are also provided three, the clamping holes 120 are arranged by taking the central point of the rotating member 100 as a circle center annular array, the clamping blocks 230 are arranged by taking the central point of the mating member 200 as a circle center annular array, the three-point fixing effect is stable, the structure is simple, and the assembly is convenient.

The surface of the rotating member 100 away from the angle grinder is attached to the surface of the mating member 200 having the locking block 230, and the two are attached to each other, so as to reduce the shaking caused by the rotation.

The six gear teeth 220 are arranged in an annular shape with the center of the through hole 210 as the center, six transmission grooves 221 are formed among the six gear teeth 220, the gear teeth 220 are used for transmitting chains of the electric chain saw, and the number and the size of the gear teeth 220 are not limited thereto and are determined according to the sizes of different types of electric chain saws.

According to the assembly mode of the product, when the angle grinder needs to be refitted into the electric chain saw, firstly, a grinding sheet on the angle grinder is detached, then the rotating piece 100 of the product is installed corresponding to an output shaft fixture block of the angle grinder, then the matching piece 200 and the rotating piece 100 are embedded and assembled to realize linkage, a chain saw support is assembled at the head of the angle grinder to be fixed, a chain of the electric chain saw is sleeved in a transmission groove 221 of the matching piece and is locked and fixed through a locking piece, the chain wheel is guaranteed not to shake radially, and the refitting is completed by installing a protective cover; the angle mill also needs to be locked through the retaining member when dress polishing piece, prevents that it from taking place radially to rock, and the retaining member is general part on present angle mill, does not do too much repeated description to this.

The basic remote, main features and advantages of the present invention have been shown and described. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for illustrating the present invention, and the present invention is not limited to the above embodiments and descriptions, and the simple modification and replacement by those skilled in the art are within the protection scope of the present invention without departing from the spirit and scope of the present invention.
