[0002] At present, as far as wheels are concerned, spoke tension has begun to attract more and more attention from players. And among the concerns about spoke tension, the most concerned are the size and uniformity of the spoke tension value. As for the spoke tension alone, it is hidden in the wheel, ensuring the durability of the wheel set, providing precise steering, rapid acceleration and powerful braking. The art of wheel set construction is to keep the spoke tension within a reasonable range as much as possible and give full play to its performance. Therefore, the tension of the steel spokes of the bicycle wheel set needs to be tested before the bicycle wheel set is sold. Existing patent number: CN205843864U9, patent name: a spoke tension meter. During the test, the spoke passes through Jiaozhou and between the tension support column A and the tension support column B. The rotation of the handle B around the hinge shaft drives the tension support column B to rotate and compress the spoke, and then the handle B compresses the digital dial indicator to realize the tension test. Such a test method has the following problems. It adopts a single bearing rotation, and the probe of the dial indicator does not move in a straight line during measurement, but moves at an angle, which will cause a certain error in the reading, and avoids the movement and contact between the dial indicator measuring rod and the aluminum alloy or steel accessories, solving the problem of errors caused by wear.
