[0002] A circular saw blade is a tool used for cutting materials, usually a round piece of metal with sharp teeth on its edge. They are widely used for cutting materials such as wood, metal, and plastic, and are commonly found in various power tools such as circular saws and table saws. The circular saw blade base clamping device is a device used to fix and clamp the circular saw blade base, and is usually used during processing, production, or maintenance. The main function of this device is to ensure that the circular saw blade is stably and safely fixed during operation to avoid inaccurate cutting or accidents caused by vibration or movement. Existing circular saw blade clamping devices often fix the circular saw blade by combining bolts and nuts, which is inconvenient to disassemble and assemble, and is not conducive to the processing of circular saw blades. Summary of the Invention

[0003] The technical problem to be solved by the utility model is that the existing circular saw blade base clamping device is troublesome to assemble and disassemble, which is not conducive to the processing of the circular saw blade.

[0005] Through the above technical solution, by installing a clamping mechanism on the base, the slider can be pushed out by rotating the knob. At this time, the first spring pushes the extrusion ring, the extrusion ring pushes the rotating ring, and the rotating ring cooperates with the slider to clamp and fix the circular saw blade. At the same time, the ball is pushed into the through hole by the second spring to fix the knob. When disassembly is required, just push the ball into the slide groove and rotate the knob in the opposite direction. The first spring will push the circular saw blade out of the clamping mechanism, which greatly facilitates the clamping and installation of the circular saw blade.

[0006] The utility model is further configured such that one end of the rotating block close to the clamping mechanism is fixedly connected to a plurality of positioning columns, and the end of the extrusion ring away from the first spring is rotatably connected to a rotating ring, and the extrusion ring, rotating ring and clamping mechanism are all concentrically arranged.

[0007] Through the above technical solution, the first spring pushes the extrusion ring, the extrusion ring pushes the rotating ring, and the rotating ring cooperates with the slider to squeeze and clamp the circular saw blade.

[0008] The present invention is further configured such that the clamping mechanism comprises a shell fixedly connected to the rotating block, a plurality of sliders are slidably connected in the shell, and a driving column is fixedly connected to the upper surface of the slider.

[0009] Through the above technical solution, the slider is driven to move by the driving column.

[0010] The utility model is further configured such that a rotating disk is rotatably connected in the shell, a plurality of guide grooves are provided on the rotating disk, the driving column passes through the sliding connection guide grooves, and a knob is fixedly connected to one end of the rotating disk away from the slider.

[0011] Through the above technical solution, the rotating disk rotates, and the guide groove on the rotating disk cooperates with the driving column on the slider to move the slider outward.

[0012] The present invention is further configured such that both ends of the knob are provided with sliding grooves, a second spring is fixedly connected in the sliding groove, an end of the second spring away from the sliding groove is fixedly connected to a ball, and a through hole is provided on the shell.

[0013] Through the above technical solution, the second spring pushes the pin into the through hole to complete the locking.

[0014] The present invention is further configured such that the ball passes through the sliding connection through hole, and one end of the ball away from the sliding groove is rounded.

[0015] The above technical solution can make it easier for the marble to enter the through hole.

[0016] The present invention is further configured such that a slot is provided on the slider, and the slot and the positioning column engage with each other.

[0017] The utility model is further configured such that the positioning column and the slider are both made of rubber, the side of the rotating ring away from the extrusion ring is provided with anti-slip grooves, a circular saw blade is provided between the slider and the rotating ring, and the positioning column passes through the circular saw blade.

[0018] Through the above technical solution, the circular saw blade can be clamped and fixed.

[0019] The beneficial effects of the utility model are as follows:

[0020] The utility model installs a clamping mechanism on the base, and the slider can be pushed out by rotating the knob. At this time, the first spring pushes the extrusion ring, and the extrusion ring pushes the rotating ring. The rotating ring cooperates with the slider to clamp and fix the circular saw blade. At the same time, the ball is pushed into the through hole by the second spring to fix the knob. When disassembly is required, it is only necessary to push the ball into the slide groove and rotate the knob in the opposite direction. The first spring will push the circular saw blade out of the clamping mechanism, which greatly facilitates the clamping and installation of the circular saw blade. BRIEF DESCRIPTION OF THE DRAWINGS
