Description
Technical Field
The utility model belongs to the technical field of saw blades, and particularly relates to a circular saw blade convenient for fastening a tool bit.
Background
The saw blade is a cutting tool and is widely applied to processing of hard and brittle materials such as building materials, woodworking, stone materials, steel materials and the like; the sintering saw blade is formed by pressing and sintering through a die, the sintering saw blade mainly comprises a base body and a tool bit, a convex connecting block is arranged at the edge of the base body for connecting and fastening the tool bit and the base body in the prior art, alloy powder can wrap the connecting block during sintering to press and sinter the connecting block, and finally the pressed tool bit can be bonded with the connecting block to strengthen the connection strength between the tool bit and the base body in the cutting process, but the connecting block is longer, the pressed tool bit and the connecting block are bonded without being bonded with the base body, the impact strength is insufficient, the tool bit can loose and fall, and the circular saw blade convenient for fastening the tool bit is provided for solving the problem.
Disclosure of Invention
In view of the above, the technical problem to be solved by the utility model is to provide a circular saw blade convenient for fastening a tool bit, which solves the problems that the tool bit is not bonded with a base body due to bonding between the tool bit and a connecting block, the impact strength is insufficient, and the tool bit can loose and fall off in the prior art.
In order to solve the technical problems, the utility model discloses a circular saw blade convenient for fastening a tool bit, which comprises: a base body and a cutter head; the edge of the base body is provided with a circle of base ring, a plurality of connecting blocks are arranged on the base ring at intervals in the circumference, the edge of the base body is provided with positioning grooves, the positioning grooves correspond to the connecting blocks one by one, and limiting holes are formed in the positioning grooves and the connecting blocks.
Further, the thickness of the base ring is smaller than that of the base body.
Further, the depth of the positioning groove is smaller than the distance from the surface of the base body to the surface of the base ring.
Further, the cutter head wraps the connecting block and fills the positioning groove and the limiting hole.
Compared with the prior art, the utility model can obtain the following technical effects:
according to the utility model, the base ring is arranged at the edge of the base body, the connecting block is arranged on the base ring, the positioning grooves are arranged at the edge of the base body, the limiting holes are formed in the positioning grooves and the connecting block, and the pressed cutter head can fill the limiting holes and the positioning grooves, so that the cutter head is connected with the base body more tightly, and the impact strength is enhanced to avoid loosening and falling of the cutter head.
Of course, it is not necessary for any one product embodying the utility model to achieve all of the technical effects described above at the same time.
