[0055] When it is necessary to release the unfolded state of the first marking rod 24 and the second marking rod 27 and the support seat 16, the operator presses the locking rod 19 from both sides of the support seat 16, and pushes the locking rod 19 into the locking groove 20 from the locking hole, and simultaneously pries the first marking rod 24 and the second marking rod 27, so that the first marking rod 24 and the second marking rod 27 rotate along the first folding portion and the second folding portion, thereby releasing the locking of the first marking rod 24 and the second marking rod 27, so as to realize the folding of the first marking rod 24 and the second marking rod 27;

[0056] like Fig.10As shown, the first fixing seat 21 further includes a first hidden groove 22, and the first hidden groove 22 is for the first contact rod 37 to be placed, so that the first contact rod 37 can be hidden and placed in the first hidden groove 22;

[0059] When it is necessary to measure the diameter at breast height of the tree 35, the first fixing seat 21 and the second fixing seat 26 in the folded state are taken out from the storage component, and the first contact rod 37 and the second contact rod 28 are unfolded, and the first contact rod 37 and the second contact rod 28 are adjusted by the telescopic sub-component.

[0066] When the first contact rod 37 and the second contact rod 28 are in the unfolded state and want to be turned into the folded state, the operator presses the locking protrusion 25 so that the locking protrusion 25 releases the limit of the locking hole and simultaneously bends the first contact rod 37 and the second contact rod 28 from the sliding direction perpendicular to the first fixing seat 21 and the second fixing seat 26 to the direction parallel to the sliding track (such as Fig.12 as shown).
