For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following describes the implementation method of the present utility model based on its overall structure.

[0029] See also Figures 1 to 3 The utility model discloses a bevel angle measuring tool, which comprises a first rotating member 1, a second rotating member 2, an inner scale plate 3 and an outer scale plate 4; wherein,

[0030] The first rotating member 1 and the second rotating member 2 are stacked along the thickness direction thereof, and both rotating members include a carrier plate 5 and a support leg portion 6 connected to the outer edge of the carrier plate 5;

[0031] A step through hole 11 is formed in the middle of the carrier plate 5 of the first rotating member 1 along its thickness direction, and the inner scale plate 3 is rotatably disposed in the step through hole 11 and is firmly connected to the carrier plate 5 of the second rotating member 2;

[0032] The outer scale plate 4 is fixed to a side of the carrier plate 5 of the first rotating member 1 away from the second rotating member 2 , and the outer scale plate 4 is located at the outer edge of the inner scale plate 3 in the radial direction.

[0033] In the above-mentioned setting method, since the inner dial 3 is rotatably arranged in the middle part of the supporting disk 5 of the first rotating member 1 along the step through hole 11 opened in its thickness direction, and it is tightly connected to the supporting disk 5 of the second rotating member 2 stacked along the thickness direction on one side of the first rotating member 1, before cutting the material, it is only necessary to operate and rotate the support feet 6 of the first rotating member 1 and the second rotating member 2 so that the two support feet 6 respectively abut against the inner wall or outer wall of the preset installation position of the workpiece, and then the angle between the inner wall or outer wall of the preset installation position of the workpiece will be displayed on the inner dial 3 and the outer dial 4 for reading, and then the cutting angle parameters of the cutting machine can be set accordingly by comparing with the angle parameters displayed on any dial, so as to cut the material and process the workpiece that can be installed at the preset installation position of the workpiece, without having to perform measurement, marking, calculation and other steps multiple times, and the measurement is more convenient and accurate. Since the two rotating parts are stacked, the supporting legs 6 connected to the outer edges of the respective supporting plates 5 do not affect each other during the rotation process, and each can perform a 360° circumferential rotation, making the operation and use of the bevel angle measuring tool more convenient and flexible.

[0034] See also Figures 1 to 3 Specifically, in this embodiment, the first rotating member 1 and the second rotating member 2 are stacked up and down, and each rotating member includes a carrier plate 5 and a support leg 6 connected to the outer edge of the carrier plate 5; the middle part of the carrier plate 5 of the first rotating member 1 is provided with a stepped through hole in the vertical direction, so that the inner scale plate 3 can be rotatably installed inside, and the inner scale plate 3 is also tightly connected to the carrier plate 5 of the second rotating member 2 below it. Therefore, by rotating the support leg 6 of the two rotating members, the two support legs 6 can be made to abut against the inner wall or outer wall of the preset installation position of the workpiece to measure the angle between the inner wall or outer wall of the preset installation position of the workpiece. The measured angle is clearly displayed on the two scale plates and the parameters can be directly read, so that the cutting angle of the cutting machine can be set according to the parameter reading value to cut a workpiece that can be installed at the preset installation position of the workpiece. More specifically, the first rotating member 1 , the supporting plate 5 of the second rotating member 2 , the inner scale plate 3 and the outer scale plate 4 are coaxially arranged, and the central axis is the connection part between the inner scale plate 3 and the supporting plate 5 of the second rotating member 2 .

Preferably, the screws 7 do not protrude from the lower disk surface of the supporting disk 5 of the second rotating member 2, nor do they protrude from the upper disk surface of the inner scale disk 3.

[0036] Specifically, in this embodiment, the inner dial 3, the outer dial 4 and the bearing plate 5 of the first rotating member 1 are flush with each other away from the disc surface of the second rotating member 2. More specifically, the bearing plate 5 of the first rotating member 1 includes a first upper disc surface, a second upper disc surface and a third upper disc surface from top to bottom, the second upper disc surface is formed by the middle part of the first upper disc surface being recessed downward, the third upper disc surface is formed by the middle part of the second upper disc surface being recessed downward, and the middle part of the third upper disc surface is penetrated downward to form a hole, so that the second upper disc surface is used to assemble the outer dial 4, and the third upper disc surface and the middle hole are used to assemble the inner dial 3, so that the upper disc surfaces of the inner dial 3, the outer dial 4 and the bearing plate 5 of the first rotating member 1 are actually flush with each other.

[0037] Specifically, in this embodiment, the bearing plate 5 of the first rotating member 1 is recessed inwardly toward the plate surface of the second rotating member 2 to form an annular groove 12 for installing an O-ring 8, and the O-ring 8 is sleeved on the outer periphery of the bottom of the inner scale plate 3 to play a shock-absorbing role in the process in which the first rotating member 1 and the outer scale plate 4 rotate synchronously relative to the second rotating member 2 and the inner scale plate 3. Preferably, the cross-sectional diameter of the O-ring 8 is slightly larger than the depth of the annular groove 12, so that the bearing plate 5 of the first rotating member 1 and the bearing plate 5 of the second rotating member 2 are respectively against the upper and lower sides of the O-ring 8.

[0039] Specifically, in this embodiment, a first pointer 91 is provided on the outer edge of the scale mark of the outer dial 4 to point to the scale mark of the inner dial 3 , and a second pointer 92 is provided on the inner periphery of the scale mark of the inner dial 3 to point to the scale mark of the outer dial 4 .

[0040] Before cutting the workpiece:

[0041] First, operate the two legs 6 included in the first rotating member 1 and the second rotating member 2 of the bevel angle measuring tool, so that the two legs 6 are respectively abutted against the two inner walls (outer walls) of the preset installation position of the workpiece to measure the angle of the preset installation position of the workpiece, and read the degree corresponding to the scale mark of the inner dial 3 according to the indication of the first pointer 91; then, according to the read degree and the type of the material to be cut, query the corresponding cutting parameters (including the bevel angle and the bevel angle) by comparing with the instruction card of the cutting machine; then set the parameters of the cutting machine, so as to cut a workpiece that is precisely adapted to the preset installation position of the workpiece; and if only beveling is required and no bevel is required, the degree corresponding to the scale mark of the outer dial 4 read according to the indication of the second pointer 92 can be used, and the bevel angle of the cutting machine can be set by comparing with the corresponding cutting parameters on the instruction card to process the workpiece. Specifically, in this embodiment, in order to operate the bevel angle measuring tool, the first pointer 91 is provided with the words "MITER CUT", and the second pointer 92 is provided with the words "SINGLE CUT", so that when the operator reads the pointer degree, he only needs to read the degree of the outer dial 4 or the inner dial 3 indicated by the pointer according to actual needs, and then find the bevel angle and bevel angle of the cutting machine accordingly, or only find the bevel angle of the cutting machine.
