Holding rod with double flat arms

The utility model discloses a holding rod with double flat arms, which comprises a tower body, a standard knot, a hoisting mechanism, an electronic control system, a mast, a variable amplitude trolley, a lifting hook, a waist ring, a pivoting support, an upper support, flat arms, a hoisting steel cable, a variable amplitude steel cable, a lower support and an amplitude variation mechanism and is characterized in that one end of the hoisting steel cable is fixed in the hoisting mechanism on the ground, after passing through the lower support, the mast, the roots of the flat arms and the variable amplitude trolley, the other end of the hoisting steel cable is fixed at the outer end parts of the flat arms; the tower body is jacked by a jacking stock arranged at the bottom of the tower body; the shapes of the cross sections of the two flat arms can be of the erected isosceles triangles; and the two flat arms are movably connected at the rotation tower body by a pin shaft arranged at the root bottom of each flat arm. For the holding rod with the double flat arms, the waist ring and a waist ring bracing wire do not need to be detached in the knot adding process of the holding rod, and the requirement on the space in the standard knot is reduced when in use.
