It is noted that the aspects described below in connection with the drawings and the specific embodiments are merely exemplary and should not be construed as limiting the scope of the invention in any way.
Fig. 1A is a schematic perspective view of an embodiment of a stepless quick-telescoping fixation rod assembly of the present invention. Fig. 1C is an AA-side cross-sectional view of fig. 1B, and fig. 1D is an enlarged schematic view of the circle in fig. 1C. Referring to fig. 1A to 1D, the stepless quick telescopic fixing rod assembly of the present embodiment includes a fixing rod 1, a fixing sleeve rod 2, a fixing nut 3, an adjusting nut 4, and a fixing sleeve rod connecting nut 5. The fixing rod 1 can freely stretch and retract in the fixing sleeve rod 2 to change the length of the two rods after being connected so as to meet different length requirements. The fixing bar 1 and the fixing loop bar 2 can also be made into the required shape.
In this embodiment, the fixing rod 1 is composed of a cylindrical guiding portion 12 at the front end, an externally connected threaded portion 11, a cylindrical hand holding portion 13, and an intermediate long threaded portion 14, wherein the externally connected threaded portion 11 is connected to an executing member, and the intermediate long threaded portion 14 is an adjustable length. The fixed sleeve rod 2 is made into a front end external thread 21 which is in threaded connection and fixed with the fixed sleeve rod connecting nut 5. The size of the guide hole 22 at the front end of the fixed sleeve rod is equal to the diameter size of the fixed rod 1, and the guide hole plays a role in guiding in the telescoping process of the fixed rod 1. And the size of the hole at the rear end of the fixed sleeve rod is larger than that of the guide hole 22 with the guide function at the front end, so that the weight and smoothness are reduced.
The fixed loop bar 2 and the fixed loop bar connecting nut 5 are fixed into a whole, the fixed bar 1 is fastened with the fixed loop bar 2 through the fixed nut 3, and the fixed bar 1 is finely adjusted with the fixed loop bar 2 through the adjusting nut 4. Fig. 1A to 1D show the fixing rod and the fixing sleeve rod fastened in an integrated form after being adjusted to a desired length dimension.

Referring to fig. 3A to 3D, the state and the adjusting nut 4, the fixed loop bar connecting nut 5, and the fixed loop bar 2 are connected together by threads. The adjustment nut 4 is rotated to generate relative rotation to the fixed rod 1, so that the expansion and contraction amount of the fixed rod can be finely adjusted, and the length of the required rod is determined. The fixing nut 3 is quickly moved along the fixing rod 1 to the position of the C surface close to the B surface by an eccentric hole 42 (larger than the screw hole by about 0.1 mm), the fixing nut 3 is radially moved to enable the internal thread of the fixing nut 3 to be meshed with the external thread of the fixing rod (the fixing nut and the fixing nut are coaxial), and the fixing nut 3 is rotated to enable a boss 31 of the fixing nut to extend into a step hole 41 of the adjusting nut until the C surface (boss end surface) is attached and fastened with the bottom surface (E surface) of the step hole. Finally, the fixing rod 1, the fixing nut 3, the adjusting nut 4, the fixing sleeve rod connecting nut 5 and the fixing sleeve rod 2 are rigidly connected into a whole, and the connected state is shown in fig. 1A. While the boss 31 is clearance-fitted with the stepped hole 41 and functions to prevent the fixing nut 3 from being released in the radial direction thereof after being forced.
