Abstract
The utility model discloses a box staff. The box staff comprises a box staff body, wherein a circle of box staff sleeve in fit with the external contour of the box staff body is arranged on the box staff body; a hole is formed in the side (on the box staff surface) of the box staff sleeve; a fastening screw is arranged at one end of the box staff sleeve and a boss extends outward from the other end of the box staff sleeve; a pointer is arranged on the boss; and the point of the pointer is vertical to the side of the box staff. The box staff has a simple structure, is convenient to use, can effectively overcome the phenomenon of reading deviation caused by too long testing distance or poor air visibility and also can be effectively applied to large-area levelling operation, thus greatly improving the overall work efficiency.
Description
Technical field
The utility model relates to the engineering construction fields of measurement, is specifically related to a kind of Sopwith staff.
Background technology
Distant due to spirit-leveling instrument and Sopwith staff in the work progresss such as elevation transmission or levelling; usually the phenomenon of reading difficulty can appear; common way is to refer on Sopwith staff by holding chi human pen; then read reading and report the testing people by holding the chi people again after moving up and down and aimed at crosshair according to testing people's indication; whole operating process is very trouble not only; and it is vertical that pen also is difficult to keep fully from the side, therefore still has certain error.
The utility model content
The utility model purpose is to provide a kind of Sopwith staff, and it can solve existing problem in background technology effectively.
In order to solve existing problem in background technology, it comprises the Sopwith staff body, on the blade of this Sopwith staff body, cover has the chi cover of its gabarit of circle applying, this chi cover is positioned at a side of chi face and offers porose, one end of described chi cover is provided with holding screw, its other end extends outward boss, and this boss is provided with pointer, and the needle point of this pointer is perpendicular to the side of Sopwith staff.
Owing to having adopted above technical scheme, the utlity model has following beneficial effect: simple in structure, easy to use, not only can effectively solve the phenomenon that deviation appears in the reading that causes because of testing hypertelorism or air poor visibility, can also effectively be applied to large tracts of land levelling operation, increase greatly whole work efficiency.
Description of drawings
In order to be illustrated more clearly in the utility model, below in conjunction with accompanying drawing, embodiment is done simple introduction.
Fig. 1 is structural representation of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, the accompanying drawing below in conjunction with in the utility model embodiment is clearly and completely described the technical scheme in the utility model embodiment.
Referring to Fig. 1, this embodiment is to be achieved by the following technical solutions, it comprises Sopwith staff body 1, on the blade of this Sopwith staff body 1, cover has the chi cover 2 of its gabarit of circle applying, these chi cover 2 sides that are positioned at the chi face are offered porose, and an end of described chi cover 2 is provided with holding screw 3, and its other end extends outward boss, this boss is provided with pointer 4, and the needle point of this pointer 4 is perpendicular to the side of Sopwith staff.
Owing to having adopted above technical scheme, this embodiment has following beneficial effect: simple in structure, easy to use, not only can effectively solve the phenomenon that deviation appears in the reading that causes because of testing hypertelorism or air poor visibility, can also effectively be applied to large tracts of land levelling operation, increase greatly whole work efficiency.
