Detailed Description

The technical solution of the present invention is further explained by the accompanying drawings and examples.

Example 1

With reference to fig. 1 to 4, a multipurpose tree angle gauge is provided, which comprises an angle gauge body 1 and a rod body 2,

angle gauge body 1 includes curved coil 11, balanced seat 12, angle gauge index 13, slope chi 14, the balanced seat 12 of 11 inboard fixed connection of curved coil, balanced seat 12 is connected with the body of rod 2 through connecting

axle

15, 2 fixed connection angle gauge indexes 13 of the body of rod, angle gauge index 13 sets up the 11 outsides of curved coil, 11 side fixed connection slope chi 14 of curved coil, slope chi 14 with the coaxial setting of curved coil 11, connecting axle 15 is in the 14 centre of a circle departments of slope chi are connected slope chi 14, balanced seat 12, the body of rod 2. In this embodiment, the slope ruler 14 is the protractor, and the body of rod 2 acts as the slope pointer, combines with slope ruler 14, can carry out the slope measurement, be provided with on the body of rod 2 be used for with slope ruler 14 complex indicator, when body of rod 2 level was placed, 14 zero degrees lines of slope ruler and indicator parallel and level, during the use, the angle value that the overlap department of slope ruler 14 and the body of rod 2 shows is the measuring slope, in some embodiments, angle gauge index 13 can act as indicator, the position that angle gauge index 13 and slope ruler 14 align is the measuring slope promptly.

In order to facilitate carrying, in some embodiments, the total length of the rod body 2 is 500mm, and the rod body includes 5 rod pieces, namely a first rod piece, a second rod piece, a third rod piece, a fourth rod piece and a fifth rod piece, wherein the rod pieces are pivotally connected through a damping rotating shaft 21, the adjustment is convenient, the structure is stable, the damping rotating shaft 21 is a straight rotating shaft, the rod pieces can rotate freely relative to the damping rotating shaft 21 and can be stably stopped at a rotation stop position, and the rod pieces can be retracted when not in use and are convenient to store. The tree height measuring device comprises a first rod piece, a second rod piece, a third rod piece, a fourth rod piece and a fifth rod piece which are all 100mm, scale marks with division values of 10mm and measuring ranges of 0-100mm are arranged on the side faces of the first rod piece, a mark line is arranged at one end, far away from a curved coil 11, of a rod body 2 and can be displayed, the mark line is arranged at one tenth of the rod body 2, and tree height can be measured by utilizing the principle of similar triangles.
