2. Since the vertical line laser module seat B2 and the horizontal line laser module seat B1 are separated independently, and then fixed to the upper and lower ends of the pendulum bracket A4 with screws, it is easy to cause vibration or thermal expansion and contraction due to temperature. Tilting, and it is easy to cause the defect that the accuracy is not easy to maintain.

Thus, the present inventor has noticed the imperfection in the design of the laser level meter A of the prior art, and in the rapidly changing market, only by continuously creating unique and innovative products is the way for manufacturers to win. Therefore, how to stand out in the highly competitive market and enhance the competitiveness of the industry in this type of product is the purpose of this application.
