Specific embodiment
In order to make the implement technical means of the utility model, creation characteristic, reach purpose and effect is easy to understand, under
Face combines and is specifically illustrating, and the utility model is further described.
As shown in figures 1-4,
Embodiment 1
A kind of concrete axial is to stretcher strain device, comprising: amesdial 1, positioning plate 2, upright bar 3 and connecting rod 4, such as Fig. 1
Shown, amesdial 1 is fixed on 2 upper end of positioning plate, and 1 lower end of amesdial is equipped with measuring staff 11, and measuring staff 11 passes through upper end positioning plate 2, surveys
11 lower end of bar, which is equipped with, surveys block, and two sides positioning plate 2 is connected by connecting rod 4, and upright bar 3 passes through lower end positioning plate 2,3 upper end of upright bar
Equipped with scaffold tower 31.
Embodiment 2
The present embodiment unlike the first embodiment, as shown in figure 3, among positioning plate 2 be equipped with locating slot 22, locating slot 22
Inside is equipped with locating convex block, and spacing block set front end is equipped with positioning wedge angle 23, is equipped with limited block 21, limited block 21 on the outside of positioning plate 2
It is equipped with limit hole 212, is equipped with threaded hole on the outside of limited block 21, stop screw 211 is connected through a screw thread with threaded hole, positioning plate
