Both ends of the pin shaft 2 are provided with limit heads.

[0034] The telescopic distance rod 1 comprises an upper distance rod 101 and a lower distance rod 102. The upper distance rod 101 is made of a hollow stainless steel tube.

[0035] The lower distance rod 102 is movably sleeved on the inner lower end of the upper distance rod 101. The lower distance rod 102 and the upper distance rod 101 can be connected by threading or clamping. In this embodiment, a threaded connection is adopted. The telescopic distance rod 1 can be freely adjusted in length according to needs.

[0036] The inner circumference of the upper distance rod 101 is provided with an internal thread, and the outer circumference of the lower distance rod 102 is provided with an external thread, and the upper distance rod 101 is threadedly connected with the lower distance rod 102. The lower distance rod 102 is screwed in or out of the upper distance rod 101 to adjust the length of the telescopic distance rod 1 of the measuring tool.

[0037] An angle adjustment assembly is provided between the two upper distance rods 101. The angle adjustment assembly is responsible for adjusting the accuracy of the unfolding angle of the two telescopic distance rods and is fastened by the locking bolt 8. The telescopic distance rod 1, the adapter and the angle adjustment assembly cooperate with each other to form a stable and accurate measuring tool.

[0038] The angle adjustment assembly includes an adjustment block 5 , a first angle adjustment ruler 6 , a second angle adjustment ruler 7 and a locking bolt 8 .

[0039] Adjustment blocks 5 are fixedly disposed on the outer ends of the two upper distance rods 101 .

[0040] The inner ends of the two adjustment blocks 5 are rotatably provided with a first angle adjustment ruler 6 and a second adjustment ruler, respectively. A through hole is provided on the adjustment block 5, and a rotating shaft passes through the through hole. The two ends of the rotating shaft extending out of the adjustment block 5 are provided with limit heads for limiting. A hole for the rotating shaft to pass through is provided on the first angle adjustment ruler 6 or the second adjustment ruler, and the rotating shaft is inserted into the hole of the first angle adjustment ruler 6 or the second adjustment ruler, and the first angle adjustment ruler 6 or the second adjustment ruler is rotatably provided on the rotating shaft.

[0041] The second adjusting ruler is provided with a receiving groove 10, and the first angle adjusting ruler 6 is slidably arranged in the receiving groove 10 of the second adjusting ruler. The first angle adjusting ruler 6 and the second angle adjusting ruler 7 are both in a horizontal state.
