Description

Technical Field

[0001] This utility model relates to the technical field of metal circular saw blades that are easy to assemble and disassemble, and in particular to a metal circular saw blade that is easy to assemble and disassemble. Background Technology

[0002] The existing patent publication number is CN213827304U, which discloses the saw blade structure;

[0003] However, many saw blade structures in the aforementioned patents and existing technologies transmit the torque of the motor output shaft to the saw blade by clamping it on both sides. However, when the saw blade is subjected to greater resistance, the center of the saw blade and the clamping parts will generate greater friction, causing the saw blade to heat up. The expansion of the saw blade after heating up will make it difficult to loosen the bolts. In addition, the aforementioned patented saw blade structures are easy to install incorrectly. If the installer is inexperienced or does not pay attention to the installation points, they may install it incorrectly. Furthermore, the saw blade can rotate when it is installed incorrectly, which can damage the saw blade.

[0004] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content

[0005] A metal circular saw blade that is easy to assemble and disassemble includes a saw blade body, an irregularly shaped saw blade is provided on the outside of the saw blade body, a central hole is provided in the middle of the saw blade body, and at least three through holes are also provided in the middle of the saw blade body, with the axis of the through holes being parallel to the axis of the central hole of the saw blade.

[0006] Preferably, the saw blade body is further provided with at least two saw blade rotation force holes and one anti-reverse installation misalignment hole in the middle, wherein the included angle (X) between the two saw blade rotation force holes is not equal to the included angle (X) between the saw blade rotation force holes and the anti-reverse installation misalignment hole.

[0007] Preferably, the included angle (X) between the saw blade rotation force hole and the anti-reverse misalignment hole is not equal to the included angle (X) between the other saw blade rotation force hole and the anti-reverse misalignment hole.

[0008] Preferably, the included angle (X) between the two saw blade rotation force holes is not equal to the included angle (X) between the saw blade rotation force hole and the anti-reverse misalignment hole.

[0009] Preferably, the inner rings of the saw blade rotation force hole and the anti-reverse misalignment hole are carburized and quenched.

[0010] Preferably, the center distance between the saw blade center hole and the center distance between the saw blade rotation force hole and the anti-reverse misalignment hole is equal.

[0011] The advantages and positive effects of this utility model are:

[0012] The structural design of the saw blade rotation force hole, saw blade center hole, and anti-reverse installation misalignment hole ensures that when the saw blade body is installed backwards, the clamping pin on the electric saw cannot pass through the saw blade rotation force hole, saw blade center hole, and anti-reverse installation misalignment hole, thus preventing the nut from being tightened and forcibly avoiding reverse installation. In addition, the clamping pin, which is fixed to the electric saw equipment at one end, passes through the saw blade body, thus forming a torque (the center distance between the saw blade center hole and the saw blade rotation force hole), which facilitates better transmission of the torque force from the motor to the saw blade body.
