[0029] Among them, the connecting component includes: a connecting end plate 901 in the shape of a channel steel structure for buckling on the cantilever member, a wing plate 902 welded on the back of the connecting end plate 901, and a channel plate 903 bolted to the wing plate 902. Two wing plates 902 and two channel plates 903 together enclose a square hole for the main arm 2 to insert. Of course, four channel plates can also be used to form a square hole for the main arm to insert, and this is not limited here; and a plurality of rope anchor piles 904 are welded on the back of the connecting end plate 901. The plurality of rope anchor piles are at both ends of the connecting end plate 901, and radial through holes are provided at intervals on each rope anchor pile 904 for ropes to pass through.
[0030] In a specific setting, the main arm 2 and the secondary arm 4 are square tubular rigid members, and the secondary arm 4 can be coaxially accommodated in the inner cavity of the main arm 2.
[0031] The main socket joint 5 is composed of two sections integrated up and down. The upper section is for one end of the main arm 2 to insert, and it is a square tube structure; the lower section of the main socket joint is used to fix the spring arm 3, which is also a square tube structure, and a radial positioning bolt is provided in the lower square tube of the main socket joint to fix the spring arm 3.

The upper section is for one end of the secondary arm 4 to insert, and it is a square tube structure; the lower section of the secondary socket joint is used to fix the spring arm 3, which is also a square tube structure, and a radial positioning bolt is provided in the lower square tube of the secondary socket joint to fix the spring arm 3.
[0032] The method for measuring the torque of the cantilever member using the above measuring instrument includes the following steps:
[0033] A. Arrive at the construction site, take out the connecting component 9, buckle the connecting end plate 901 of the connecting component 9 on the cantilever member 1 to be detected, and bind the entire connecting component 9 to the cantilever member 1 with a rope;
[0034] B. Insert one end of the main arm 2 into the square hole of the channel plate 903 of the connecting component 9;
[0035] C. Check whether the two ends of each spring plate of the spring force arm 3 are fastened to the main sleeve joint 5 and the sub-sleeve joint 6. Then, insert the square tube at the upper section of the main sleeve joint 5 into the main force arm 2.

[0038] It should be noted that before the detection, each scale indicated by the pointer 7 on the scale 8 corresponds to a specific force applied to the sub-force arm 4, and this value can be obtained through experiments. When detecting the cantilever member in the field, according to the scale value indicated by the pointer 7, the force applied to the sub-force arm 4 can be obtained in reverse. According to the value of the set force, the moment received by the concrete pole (cantilever member) can be calculated, and then the anti-tipping performance of the concrete pole can be evaluated to eliminate potential safety hazards.
