The invention discloses a combined-and-separated-type anti-theft window. The combined-and-separated-type anti-theft window comprises an anti-theft window body. A connecting part is arranged between ananti-theft grid of the anti-theft window body and a window sash, and the upper end and the lower end of the connecting part are slidably matched in a window frame of the anti-theft window body. One end of the connecting part is connected with the anti-theft grid, and the other end of the connecting part is connected to a frame of the window sash through a special lock. Concealing boxes are arranged on the window frame connected with the anti-theft grid and the connecting part correspondingly and used for concealing the anti-theft grid. The special lock is applied to the combined-and-separated-type anti-theft window and comprises a spring positioning plug pin mechanism and a key separating mechanism, the spring positioning plug pin mechanism acts on the anti-theft grid, and the key separating mechanism acts on the window sash. The structure is simple, design is reasonable, functionality is higher, using is convenient, the anti-theft window can be fixed randomly, hand clamping is prevented, and the problems of a traditional integrated anti-theft window are solved.

The invention discloses a convenient-to-wear protective device for electrician outdoor operation, which comprises a glove main body, the top end of the glove main body is provided with a tightening and closing mechanism, the tightening and closing mechanism comprises two I-shaped base blocks, and the surface of the glove main body is symmetrically provided with two strip-shaped slideways corresponding to the I-shaped base blocks. The two ends of the I-shaped base block are located on the inner side and the outer side of the glove body respectively, and an integrated first clamping head is arranged on the surface of the top end of the I-shaped base block. By arranging a tightening and closing mechanism composed of an I-shaped base block, a strip-shaped sliding way, a first clamping head and a first clamping hole, after an operator wears the glove body on the hand, the end of the glove body can be tightened and closed through the tightening and closing mechanism, and therefore the operator can wear the glove body more conveniently; the glove main body is prevented from falling off from the hand of an operator, and the stability in subsequent use is improved.

The invention discloses an irregular small-sized land area measuring method based on a photoelectric measuring technology. The irregular small-sized land area measuring method is characterized by comprising the following steps: 1) determining a positioning base point in a land central area; 2) building laser beams which are vertical to one another on the basis of the positioning base point in order to partition a land into four areas; 3) erecting a measuring cable along an outer edge of each area, wherein photoelectric measuring instrument modules are distributed on the measuring cable at equal intervals; 4) acquiring distances between the photoelectric measuring instrument modules and the positioning base point, and transmitting the distances to a control terminal; 5) calculating a land graph and an area according to data acquired through the distances among photoelectric measuring instruments through the control terminal. By adopting the irregular small-sized land area measuring method based on the photoelectric measuring technology, distance information acquired by the photoelectric measuring instruments which are arranged along the edges of the land is utilized in conjunction with equal-interval arrangement of adjacent photoelectric measuring instruments, so that a coordinate graph of the land edges can be drawn, and high boundary annotation accuracy and high size control accuracy are realized; the method is easy and convenient to operate, and contributes to proceeding of outdoor operation.
