Description

Technical Field

[0001] This utility model relates to the field of circular saw technology, specifically a circular saw guide rail structure. Background Technology

[0002] In the woodworking industry, circular saws, as efficient and precise cutting tools, are widely used in cutting various types of wood. Traditional circular saw systems are typically equipped with long, narrow guide rails. These rails are designed to provide a stable linear movement path for the circular saw, ensuring the straightness and accuracy of the cutting process. The guide rails are connected to the circular saw body via a specific slot structure, allowing the circular saw to cut along the preset trajectory of the guide rails, thereby greatly improving work efficiency and cutting quality.

[0003] However, current circular saw guide rail systems on the market have a significant limitation: the compatibility between the guide rail and the circular saw is highly specialized. Specifically, most long guide rails are custom-designed for specific models or brands of circular saws, with their dimensions, shapes, and connection mechanisms strictly matching a particular type of circular saw. While this design ensures a tight fit and optimal performance between the circular saw and the guide rail to some extent, it also introduces serious compatibility issues. Other types or brands of circular saws often cannot directly use these guide rails designed specifically for these models. This situation presents the following problems: for users who own multiple types of circular saws, in order to fully utilize the performance of each type, they have to purchase multiple sets of matching long guide rails, which undoubtedly increases costs significantly. Furthermore, multiple sets of long guide rails are inconvenient to store. Utility Model Content

[0004] In view of the above-mentioned defects in the prior art, the purpose of this utility model is to provide a circular saw guide rail structure.

[0005] The technical solution of this utility model is: a circular saw guide rail structure, which includes a circular saw and a long guide rail. The top of the long guide rail is provided with a front-to-back extending convex rail. It also includes an auxiliary guide rail for connecting the long guide rail and the circular saw.

[0006] The bottom right end of the auxiliary guide rail has a through groove. The auxiliary guide rail is placed on top of the long guide rail, and the convex rail is inserted into the groove and slides back and forth with the groove.

[0008] Furthermore, a boss is provided at the bottom of the auxiliary guide rail, and the boss is supported on the upper end of the long guide rail.

[0009] Furthermore, the upper middle part of the auxiliary guide rail has a first T-shaped groove that runs through the front and back. The first T-shaped groove is for a stop block to be inserted into. The lower end of the stop block has a T-shaped block that slides in conjunction with the first T-shaped groove. The front end face of the circular saw rests against the rear end face of the stop block.

[0010] Furthermore, the locking device includes a first locking mechanism and two second locking mechanisms, the first locking mechanism being used to fix the front end of the circular saw and the second locking mechanisms being used to fix the rear end of the circular saw.

[0011] Furthermore, the first locking mechanism includes a first pressure plate, a first screw, and a first locking knob. The lower end of the first screw has a first circular piece, and the upper right end of the auxiliary guide rail has a second T-shaped groove that runs through the front and back. The first circular piece is inserted into the second T-shaped groove and slides back and forth with the second T-shaped groove. The first pressure plate has a first through hole that runs vertically through the front and back. The first screw extends vertically through the first through hole. The first locking knob is threaded to the upper end of the first screw and presses against the top of the first pressure plate. The left end of the first pressure plate has a first hook, and the lower end of the circular saw has a frame. The first pressure plate presses against the top of the front end of the frame, and the first hook is engaged with the inner wall of the front end of the frame.
