DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of the technical solutions appears to be contradictory or unable to be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection of the present application.

[0021] In the embodiments of the present application, please refer to Figures 1-5 As shown, a quick - installation structure for a saw blade chuck mainly includes: a saw blade 1, with a locking hole 2 opened at one end thereof; an installation chuck 3 for quickly clamping and fixing the saw blade 1, including: an installation handle 31, on which an installation groove 311 and a receiving hole 312 are opened. A sliding rod 4 and a plurality of steel balls 5 are arranged in the receiving hole 312. A torsion spring 6 is arranged on the installation handle 31, and one end foot of the torsion spring 6 is fixed in the installation groove 311; a fixing ring 32 is installed on the installation handle 31, and the torsion spring 6 is placed inside the fixing ring 32; a rotating ring 33 is rotatably arranged on the installation handle 31 and is fixed to the other end corner of the torsion spring 6. The inner wall thickness of the rotating ring 33 is not uniform, forming a first rotating groove 332 with a constant wall thickness and a second rotating groove 333 with a gradually changing wall thickness. Rotating the rotating ring 33 can adjust the moving space of the steel balls 5 to achieve quick disassembly and assembly of the saw blade 1.

[0022] Next, some preferred / improved embodiments based on the above - mentioned embodiments will be further elaborated. Any one or a combination of multiple of the following embodiments can be selected.

[0023] As Figures 3-4 shown, the first rotating groove 332 is used to provide a moving space for the sliding rod 4 when the rotating ring 33 rotates, and the second rotating groove 333 is used to adjust the moving space of the steel balls 5. By rotating the rotating ring 33, due to the limitation of the second rotating groove 333, the moving space of the steel balls 5 gradually becomes larger or smaller, enabling quick insertion and removal of the saw blade 1.

[0024] Furthermore, a lug is formed on the rotating ring 33 to facilitate the operation of rotating the rotating ring 33.

[0025] Furthermore, a limiting ring 34 is installed on the installation handle 31. The limiting ring 34 is fixed to the installation handle 31 through a hoop, used to fix the position of the torsion spring 6, and at the same time limit the position of the rotating ring 33 through cooperation with the hoop.

[0026] Specifically, the steel balls 5 include a first steel ball and a second steel ball. The first steel ball is in contact with the sliding rod 4, and the second steel ball is used to abut against the second rotating groove 333.

[0027] Furthermore, a fixing hole 331 is arranged inside the rotating ring 33 for fixing the other end foot of the torsion spring 6, facilitating the reset of the rotating ring 33 driven by the torsion spring 6.

[0028] In use, only need to rotate the rotating ring 33 and keep the current state. At this time, the sliding space of the steel ball 5 becomes larger, and the saw blade 1 can be inserted into the installation groove 311. The locking hole 2 coincides with the accommodating hole 312, and the steel ball 5 is placed in the locking hole 2. Release the rotating ring 33. Under the action of the torsion spring 6, the rotating ring 33 resets, the sliding space of the steel ball 5 becomes smaller, and the saw blade 1 is clamped by the steel ball 5, realizing quick installation. If the saw blade 1 needs to be detached, rotate the rotating ring 33 again and pull out the saw blade 1.

[0029] Rotating the rotating ring 33 can adjust the moving space of the steel ball 5 to realize the quick disassembly and assembly of the saw blade 1, with simple, fast, convenient and efficient operation.
