[0021] As Figures 1-4 shown: It includes a holding rod 1. A groove 11 is opened on the top surface of the holding rod 1. A bonding plate 2 is provided at the top end of the holding rod 1. A connecting plate 21 is fixedly installed on the side wall of the bonding plate 2. Symmetrically distributed shaft rods 23 are fixedly installed on the front and rear sides of the connecting plate 21. The shaft rods 23 are rotatably installed on the side wall of the groove 11 through bearing rings. Angle measuring discs 3 for measuring the inclination angle of the bonding plate 2 are fixedly installed on the front and rear sides of the top surface of the holding rod 1. A bonding strip 12 for contacting the surface of the steel pipe is provided on the right side of the holding rod 1. The bonding plate 2 is made of transparent acrylic material. The bonding plate 2 and the connecting plate 21 are integrally formed. A scale groove 31 is opened on the side wall of the angle measuring disc 3. A relief groove 22 opposite to the position of the scale groove 31 is opened on the side of the bonding plate 2 close to the scale groove 31. The scale groove 31 is clamped inside the relief groove 22. The scale groove 31 and the shaft rod 23 are coaxially arranged. By providing the holding rod 1, the bonding strip 12, the bonding plate 2, the connecting plate 21, the relief groove 22, the shaft rod 23, the angle measuring disc 3 and the scale groove 31, the inclination angle of the end face of the steel pipe can be measured. The side surface of the bonding plate 2 is attached to the end face of the steel pipe, and the bonding strip 12 is attached to the side wall of the steel pipe. At this time, the overlapping part of the relief groove 22 and the scale groove 31 is the included angle between the bonding plate 2 and the holding rod 1, and the degree of this included angle is the inclination angle of the end face of the steel pipe, achieving the purpose of facilitating the accurate measurement of the inclination angle of the end face of the steel pipe. The inclination angle of the end face of the steel pipe can be directly obtained, which is simple and convenient to use and has strong practicability;

[0022] Embodiment 2:

[0023] As Figures 1-3As shown: there are two bonding strips 12, which are fixedly mounted on the side wall of the gripping rod 1, and the two bonding strips 12 are symmetrically distributed on the upper and lower sides of the side wall of the gripping rod 1. The bonding strips 12 can reduce the contact area between the side of the gripping rod 1 and the surface of the steel pipe, so as to reduce the resistance when the steel pipe is rotated;

[0024] Embodiment 3:

[0025] like Figures 1-3 As shown: a gripping groove 13 is opened in the middle of the front side of the gripping rod 1, and a silicone pad is bonded to the inner wall of the gripping groove 13. The user's palm passes through the gripping groove 13 to hold the gripping rod 1 in the upper hand, and the silicone pad can improve the comfort of holding the gripping rod 1.

[0026] Working principle and use process of the utility model: When using the steel pipe end face bevel angle detection tool, the steel pipe is placed flat on the table and the end to be measured is kept suspended. Then the user passes the palm of one hand through the gripping groove 13, and then fits the bonding strip 12 on the surface of the measuring end of the steel pipe. Then the user turns over the bonding plate 2 with the other hand, and observes the angle between the bonding plate 2 and the holding rod 1 through the angle measuring disk 3, so that the angle between the bonding plate 2 and the holding rod 1 is 90°, and then moves the bonding plate 2 and the holding rod 1 until the bonding plate 2 contacts the end face of the steel pipe. By setting the bonding plate 2 as a transparent acrylic plate, it is possible to observe whether the bonding plate 2 is completely fitted with the end face of the steel pipe. If the side of the bonding plate 2 is completely fitted with the end face of the steel pipe, it can be known that the end face of the steel pipe is a plane, and the measurement is completed. If the bonding plate 2 is not fitted with the end face of the steel pipe, it can be known that the end face of the steel pipe is an inclined surface. Then the steel pipe is rotated until the end face of the steel pipe is completely fitted with the side of the bonding plate 2. Then, by observing the position where the give way groove 22 overlaps with the scale groove 31, the degree of the angle between the bonding plate 2 and the gripping rod 1 can be read, and the degree is the inclination angle of the end face of the steel pipe.

[0027] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
