Description

Technical Field

[0001] This utility model relates to a ring saw capable of grooving completely along the edge. Background Technology

[0002] Traditional ring saws, due to structural limitations in the placement of the main unit and saw blade, result in a certain distance between the saw groove and the wall during the working process, making it impossible to perform grooving completely flush with the wall. Currently available ring saws use ring-shaped saw blades with a large hollow center. The height of the fastening structure exceeds the limit of the saw teeth, causing fasteners and related structural components to extend beyond the tooth height, thus preventing grooving completely flush with the wall. Furthermore, existing ring saw blades are hollow internally, resulting in low structural strength and a short service life. Summary of the Invention

[0003] This invention provides a ring saw capable of grooving completely along the edge.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A ring saw capable of grooving completely along the edge includes a housing and a saw blade assembly disposed at the end of the housing. The saw blade assembly is circular. A drive mechanism capable of driving the saw blade assembly to rotate is disposed at the front end of the housing. A handle is disposed on the housing. The drive mechanism extends horizontally from left to right and is provided with a drive shaft. A drive gear is disposed at the end of the drive shaft. The saw blade assembly is located outside the housing and the handle in its axial direction. The saw blade assembly includes a circular support plate and an annular saw blade disposed around the outside of the circular support plate. A circular hole is provided near the edge of the circular support plate. The annular saw blade includes drive teeth disposed on the inner edge and cutting teeth disposed on the outer edge. The circular hole of the circular support plate cooperates with the drive gear at the end of the drive shaft, and the drive gear meshes with the drive teeth on the inner side of the annular saw blade.

[0005] Preferably, the driving mechanism is a motor.

[0006] Preferably, the shell is a cylindrical structure.

[0007] Preferably, the handle includes a square frame in the middle and a first handle and a second handle on the upper and lower sides of the square frame, and the housing passes through the square frame and is connected and fixed to the side wall of the square frame.

[0008] Preferably, a handle is rotatably provided at the other end of the housing opposite to the saw blade assembly.

[0009] Preferably, the handle has a "D" shaped structure.

[0010] Preferably, mounting portions are provided on the upper and lower sides of the circular hole.

[0011] Preferably, a guard plate is provided on the side of the drive mechanism, and the saw blade assembly is fixed to the outside of the guard plate by screws and the mounting part of the circular support plate.

[0012] Compared with the prior art, the saw blade assembly of the ring saw that can cut grooves completely along the edge is located on the outermost side. Since there are no parts protruding from the outer side of the saw blade assembly, the saw blade assembly can cut grooves on the wall in front of it while close to the wall. The inner side of the ring saw blade of the saw blade assembly is provided with a circular support plate, which makes the ring saw blade stronger, more stable in cutting performance, and extends its service life.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] like Figures 1 to 4 As shown, a ring saw capable of grooving completely along the edge includes a housing 1 and a saw blade assembly 2 disposed at the end of the housing 1. The saw blade assembly 2 is circular. A handle 3 is rotatably disposed at the other end of the housing 1 opposite to the saw blade assembly 2. A drive mechanism 11 capable of driving the saw blade assembly 2 to rotate is disposed at the front end of the housing 1. The drive mechanism 11 extends horizontally from left to right and is provided with a drive shaft 111. A drive gear 12 is disposed at the end of the drive shaft 111. The drive mechanism 11 is a motor. The housing 1 has a cylindrical structure and a handle 4 is disposed on the housing 1. The handle 4 includes a square frame 42 located in the middle and a first handle 41 and a second handle 43 located on the upper and lower sides of the square frame 42. The housing 1 passes through the square frame 42 and is connected and fixed to the side wall of the square frame 42. The saw blade assembly 2 is located outside the housing 1 and the handle 4 in its axial direction.

[0019] The handle 3 has a "D" shaped structure. The saw blade assembly 2 includes a circular support plate 21 and an annular saw blade 22 surrounding the outer side of the circular support plate 21. The circular support plate 21 includes a circular hole 211 near the edge and mounting portions 212 on the upper and lower sides of the circular hole 211. The annular saw blade 22 includes a drive tooth 221 on the inner edge and a cutting tooth 222 on the outer edge.

[0020] A guard plate 5 is provided on the side of the drive mechanism 11. The saw blade assembly 2 is fixed to the outside of the guard plate 5 by screws and the mounting part 212 of the circular support plate 21. The screws do not protrude from the outside of the saw blade assembly 2. The circular hole 211 of the circular support plate 21 is engaged with the drive gear 12 at the end of the drive shaft 111 and the drive gear 12 meshes with the drive teeth 221 on the inner side of the annular saw blade 22. Thus, the drive mechanism 11 drives the annular saw blade 22 to rotate at high speed through the drive gear 12 to achieve cutting and grooving.

[0021] like Figure 2 The diagram shows the ring saw in use. Since the saw blade assembly 2 is located outside the housing 1 and handle 4, and no parts protrude from the outside of the saw blade assembly 2, the saw blade assembly 2 can cut grooves into the wall in front of it while flush against the wall 100, with the wall 100 on the right. If the wall 100 is on the left, simply flip the ring saw to make the saw blade assembly 2 cut grooves into the wall in front of it while flush against the left side of the wall 100. The handle 4 includes a first handle 41 and a second handle 43 on both the upper and lower sides, facilitating the flipping of the ring saw to cut grooves into the wall from different angles.

[0022] Left-handed and right-handed users can flip the ring saw so that the first handle 41 or the second handle 43 is on top, according to their own usage habits, so as to selectively hold the first handle 41 or the second handle 43, and turn the handle 3, holding the first handle 41 or the second handle 43 with one hand and the handle 3 with the other hand to use the ring saw.

[0023] The saw blade assembly 2 of this utility model, which is capable of cutting grooves completely along the edge, is located on the outermost side. Since no parts protrude from the outer side of the saw blade assembly 2, the saw blade assembly 2 can cut grooves against the wall 100 in front of it. A circular support plate 21 is provided on the inner side of the annular saw blade 22 of the saw blade assembly 2. The annular saw blade 22 has higher strength, more stable cutting performance, and extended service life.

[0024] Finally, it should be noted that the above embodiments only illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
