The invention relates to the technical field of engineering surveying and mapping, and discloses a novel multifunctional high-precision engineering surveying and mapping box staff. The novel multifunctional high-precision engineering surveying and mapping box staff comprises a main body. The top of the main body is provided with bearing seats rotatably connected with the left and right ends of a winding roller, the exterior of the winding roller is provided with a lifting rope, the lower end of the lifting rope is provided with a third fixing plate, and the lower portion of the third fixing plate is provided with a surveying and mapping head. The middle portions of the left and right side walls of the main body are provided with avoidance grooves, the middle portions of the avoidance grooves are provided with rotating shafts, the middle portions of the rotating shafts are rotatably connected with the ends, close to the center of the device, of ejecting rods, and the ends, away from thecenter of the device, of the ejecting rods are rotatably connected with the lower portions of sliding sleeves. According to the novel multifunctional high-precision engineering surveying and mappingbox staff, first limiting grooves and second limiting grooves are formed in the upper portions of the sliding sleeves and connected with stop rods in a clamping manner respectively, so that the wholedevice is supported by the sliding sleeves and sliding rods when in use; and the sliding sleeves, the ejecting rods and supporting rods are completely retracted into the avoidance grooves on the leftand right sides when the device is retracted, so that the portability of the device is improved.

    本发明涉及工程测绘技术领域,公开了一种新型多功能高精度的工程测绘塔尺,包括主体,主体的顶部设有轴承座,轴承座转动连接缠绕辊的左右两端,缠绕辊外部设有吊绳,吊绳的下端设有第三固定板,第三固定板的下部设有测绘头,所述主体的左右侧壁中部设有让位槽,让位槽的中部设有转轴,转轴的中部转动连接顶杆的靠近装置中心的一端,顶杆的远离装置中心的一端转动连接滑套的下部。本发明适用于一种新型多功能高精度的工程测绘塔尺,通过在滑套的上部设置第一限位槽和第二限位槽分别与档杆卡接,使得装置在使用时通过滑套和滑动杆支撑整个装置,当装置收拢时,滑套、顶杆和支撑杆完全收拢在左右两侧的让位槽中,提高了装置的便携性。
