A conventional steering wheel correction tool, as shown in the Taiwan Patent No. D129704, is attached to the opposite inner side edges of the steering wheel ring by means of an arcuate groove of the opposite outer side of the two movable feet. For the purpose of the steering wheel. Since it has only two fixed points with the steering wheel system, and the contact area between the two movable feet and the steering wheel ring is not large, the combination stability is not good, and the sway is easy to occur, thereby affecting the accuracy of the correction. In particular, the level on the conventional steering wheel correction tool only allows the corrector to know whether the steering wheel has a rotational deviation through the bubble therein. As for the actual rotational deviation value, it cannot be displayed reliably, so the corrector can only rely on the experience visual inspection. Judgment to make corrections and adjustments, so there will be problems of poor calibration accuracy, and it is necessary to repeatedly and repeatedly travel between the observation level and the adjustment of the transmission mechanism to achieve the purpose of correction, thus making the calibration efficiency very poor.

The main purpose of this creation is to solve the problems of poor combination stability, poor correction accuracy and poor calibration efficiency of the conventional steering wheel correction tool.

This creation provides a steering wheel correction tool that includes a tube, two jaws, a level and an angle meter. Wherein, the two clamping jaws are respectively coupled to the two ends of the seat tube, and can adjust the distance and the rotation angle relatively close to or away from each other, and each clamping jaw has two fixing rods for maintaining the separation distance, and the circumference of each fixing rod The surface is formed in a concave arc shape, so that the two fixing rods of the two jaws can be stably clamped and fixed on the inner edge of the steering wheel of the steering wheel. The level is disposed at the center of the seat tube for detecting whether the steering wheel has a rotational deviation. The angle meter is coupled to the center of the seat tube for measuring the direction and angle of rotation of the steering wheel.

The steering wheel correction tool provided by the present invention is capable of being clamped to the inner edge of the steering wheel ring by the two fixing rods of the two clamping jaws, so that the steering wheel correction tool can form four fixed points with the steering wheel ring, thereby further Achieve good binding stability and accuracy. In particular, the angle and the angle of rotation of the steering wheel can be measured and displayed clearly and accurately by the angle meter, so that the calibration personnel can easily and quickly and accurately adjust and correct the rotation deviation of the steering wheel. Greatly improve calibration efficiency. Moreover, the steering wheel correction tool of this creation is also very simple in operation, and the storage is also very convenient and does not take up space.

The portion 221 has a screw hole 222 at an end surface of the shaft 220. The two fixing rods 23 are coupled to each other at a spaced distance The fixing piece 22 is close to the rear side at both ends, and the circumferential surface of each of the fixing rods 23 is concavely curved. The fixing button 24 has a screw 240 that can be inserted into the through hole 210 through the corresponding long hole 13 and screwed into the screw hole 222 of the shaft 220 to fix the screw hole 222. The button 24 and the convex portion 221 are clamped to the front and rear sides of the seat tube 10 to achieve the purpose of positioning the jaw 20 on the seat tube 10.

The level 30 is embedded in the front side of the center of the seat tube 10 for detecting whether the seat tube 10 has a level. When the steering wheel correction tool is fixedly coupled to the steering wheel 50, the steering wheel 50 can be detected. Is there a rotation deviation?

The angle meter 40 is provided with at least one magnetic member 41 at the bottom for being adsorbed on the iron base 12. The angle meter 40 is configured to measure the direction and angle of rotation of the seat tube 10, and the direction and angle of rotation of the steering wheel 50 can be measured when the steering wheel correction tool is fixed to the steering wheel 50.
