Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

As shown in fig. 1-3, the utility model provides a telescopic measurement scale is used in geographical mapping, including inside and outside shrink a plurality of chi areas 1 that cup joint and integrative butt joint in the chi head 2 of every chi area 1 one end, the front end surface that is located the chi head 2 of outer lane all is provided with one and wipes handle 3, the internal peripheral fixed glue that wipes handle 3 has the cotton 4 of wiping, and wipes the outer peripheral face laminating of cotton 4 and the chi head 2 that is located the inner circle, wipes a plurality of picture pegs 5 of rear side surface fixedly connected with of handle 3, and every picture peg 5 all blocks and rabbets in the inside of chi head 2.

In an alternative embodiment, a movable piece 7 is movably embedded in the interior of the ruler head 2 at the rear side of the wiping handle 3, and the movable piece 7 is the same as and vertically parallel to the wiping handle 3 in shape.

In an optional embodiment, an L-shaped limiting member 8 is fixedly connected to one side of each board 5 on the front surface of the movable member 7, and a limiting hole 9 capable of matching with the bottom end of the L-shaped limiting member 8 is formed through the rear end of the board 5.

In an optional embodiment, the side surface of the movable member 7 is fixedly connected with the dial shaft 6, and the side surface of the ruler head 2 is provided with a vertical preformed groove for the dial shaft 6 to move up and down.

In an alternative embodiment, a limit spring 10 is fixedly connected to the inner part of the ruler head 2 and the two top ends of the movable piece 7.

The working principle is as follows: when the traditional telescopic measurement scale for geographical mapping is used for measuring the earth surface, the lower surface of the scale is easily stained with soil and grass scraps, and the scale is easily wrapped, clamped and retracted together with the soil and grass scraps when retracted; through the design of the plug board 5, the limiting hole 9, the moving part 7, the L-shaped limiting part 8 and the limiting spring 10, the wiping handle 3 is convenient to connect and fix, specifically, the wiping handle 3 is pasted on the front end surface of the ruler head 2 from bottom to top, then the shifting shaft 6 is pinched to push the moving part 7 upwards, then the plug board 5 on the rear surface of the wiping handle 3 is clamped into the ruler head 2, then the shifting shaft 6 is loosened, the limiting spring 10 enables the bottom end of the L-shaped limiting part 8 to be clamped into the limiting hole 9 at the corresponding position through downward elastic thrust, and therefore the wiping handle 3 is fixed at the end part of the ruler head 2; through the design of the poking shaft 6, the wiping handle 3 can be conveniently detached from the ruler head 2 and then cleaned or replaced.
