[0002] Urban and rural planning is a comprehensive deployment, specific arrangement, and implementation management of urban and rural economic and social development, land use, spatial layout, and various constructions within a certain period. Urban and rural planning needs to comprehensively consider factors such as population, economy, society, and environment in order to achieve orderly, coordinated, and sustainable development of urban and rural areas. It involves the collaborative cooperation of multiple fields and professions such as urban design, regional planning, transportation planning, and ecological planning. During the on-site inspection of urban and rural planning, it is necessary to use a measuring tape to conduct on-site measurements.
[0003] Existing technologies, such as the utility model with announcement number CN2485625Y, relate to the field of measuring tapes. Specifically, it is a measuring tape housing with a protective edging. An open edging is provided at the joint of the upper and lower housings, which are fixedly connected. Multiple fixing nails on both sides of the edging are connected to the upper and lower housings respectively. The fixing nails have "+" grooves along the axis and have barbed heads, making the connection very secure. Using a measuring tape with the edging provides a good feel and prevents slippage and damage. It is a novel packaging for measuring tapes, giving people a sense of novelty and aesthetics, increasing purchasing desire, and opening up a broad market. However, during use, the measuring tape needs to be hooked onto an object before it can be pulled open. The hook is prone to loosening and falling off, making it difficult for a single person to operate. It requires two people to cooperate to measure, consuming a lot of time and increasing the difficulty of operating the equipment.
[0004] To address the issue that measuring tapes need to be hooked onto an object before they can be pulled out, making it difficult for a single person to operate and requiring two people to work together, thus wasting a lot of time and increasing the difficulty of operating the equipment, existing technology uses a two-person collaboration method. However, this increases the difficulty of operating the equipment and leads to inconvenience in its operation. Utility Model Content

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] In this invention, by setting up a fastening device and a friction device, during measurement, the object is placed between the connecting rod and the square rod. At this time, the knob is turned, and the knob drives the threaded rod to rotate. As the threaded rod moves, it squeezes the pad, clamping the object between the pad and the round pad. At this time, the head of the ruler is fixed. Then, the shell is pulled to pull out the ruler. During the movement of the ruler, the pressure spring generates elastic force to squeeze the friction pad against the ruler and clean the surface of the ruler. This reduces the situation where debris sticks to the surface of the ruler, making it difficult for the user to see the scale. By setting up this invention, it is easy to fix the head of the ruler, reducing the possibility of the hook coming off when the operator pulls the ruler. It is convenient for single-person use of the equipment and increases the stability of the equipment. Attached Figure Description
