It is equipped with the first groove equipped with the first convex block, the other end, one end of the second ruler plate is equipped with and the first groove size shape
Identical second convex block, the other end are equipped with the second groove identical with the first size of lug shape, and second convex block is embedding
Enter first groove.
Preferably, the first ruler plate be internally provided with perforation three sides the first deep trouth, the second ruler plate it is interior
Portion is equipped with the second deep trouth of three sides of perforation, and the opening direction of first deep trouth and second deep trouth is on the contrary, described the
One deep trouth is internally provided with the first centrally located tied rope axis, and being internally provided with for second deep trouth is centrally located
Second tied rope axis is connected with elastic string between the first tied rope axis and the second tied rope axis.
Preferably, the slot bottom of first deep trouth is located at the medial surface of the first ruler plate, the slot bottom of second deep trouth
Positioned at the lateral surface of the second ruler plate.
Preferably, first convex block, first groove, second convex block and second groove are that both sides are
Plane, the arch door shape structure that top is cambered surface.
The utility model has the beneficial effects that：
One dimensional measuring instrument for using of the convenience of the utility model, by the first ruler plate being stitched together and the second ruler
Plate is cleverly coordinated, and longer distance can be measured；First deep trouth, the second deep trouth and elastic string, elastic string energy are set
So that the first ruler plate and the second ruler plate is closely stitched together, elastic string can also in the inside of the first deep trouth and the second deep trouth and
Opening moves；First ruler plate and the second ruler plate are carried out by the first convex block, the second deep trouth and the second convex block and the first groove
Splicing repeatedly, error are small.

Specific implementation mode
Specific embodiment of the present utility model is referring to Fig. 1-8：
The utility model mainly discloses a kind of convenience one dimensional measuring instrument for using, and common board foot is this field skill
The prior art known to art personnel, therefore be no longer described in greater detail, with the schema hereinafter compareed, main expression with
The related structural representation of the utility model feature also need not completely be drawn according to actual size, first explanation.
Embodiment one, such as Fig. 3, a kind of one dimensional measuring instrument for using of convenience, including the first ruler for being stitched together
Plate 1 and the second ruler plate 2, the first ruler plate 1 is identical as the shape of the second ruler plate 2, and one end of the first ruler plate 1 is equipped with
First convex block 11, the other end are equipped with the first groove 12, and one end of the second ruler plate 2 is equipped with and first groove, 12 size shape
Identical second convex block 21 of shape, the other end are equipped with the second groove 22 identical with 11 size shape of the first convex block, and described the
Two convex blocks 21 are embedded in first groove 12, first convex block 11, first groove 12, second convex block 21 and described
Second groove 22 is the arch door shape structure that both sides are plane, top is cambered surface.
Embodiment two, it is essentially identical with embodiment one such as Fig. 1-3, the difference is that, the inside of the first ruler plate 1
The first deep trouth 13 equipped with three sides of perforation, the second deep trouth 23 for being internally provided with three sides of perforation of the second ruler plate 2,
First deep trouth 13 is with the opening direction of second deep trouth 23 on the contrary, being internally provided with positioned at centre for first deep trouth 13
First tied rope axis 14 of position, second deep trouth 23 are internally provided with the second centrally located tied rope axis 24, and described
It is connected with elastic string 3 between one tied rope axis 14 and the second tied rope axis 24, the slot bottom of first deep trouth 13 is located at described the
The medial surface of one ruler plate 1, the slot bottom of second deep trouth 23 are located at the lateral surface of the second ruler plate 2.
When measurement, the first ruler plate 1 and the second ruler plate 2 are docking together, are placed on initial position and measure by such as Fig. 3, this
When, the first ruler plate 1 is located at left side, the second ruler plate 2 is located at right side；The second ruler plate 2 is set to be detached from the first ruler plate 1 later, it, will such as Fig. 4
Second convex block 21 takes out from the first groove 12；And then, such as Figures 5 and 6, the second ruler plate 2 is revolved clockwise around the first ruler plate 1
Turn, the first groove 12 and the second groove 22 enable elastic string 3 to pass through；Then, such as Fig. 7, the second ruler plate 2 is moved to the first ruler
The other side of plate 1, the first ruler plate 1 remain motionless, and the second ruler plate 2 is moved only with respect to the first ruler plate 1, the second ruler plate
2, which itself remain lateral, does not rotate；Finally, such as Fig. 8, the second ruler plate 2 and the first ruler plate 1 are spliced together, make
One convex block 11 is embedded in the second groove 22；Repeatedly, until measuring the distance for needing to measure.
