Embodiment 1
[0027] A new shaft structure is provided in this embodiment, such as Figure 1-2 As shown, it includes an upper rod fixed shaft 1, a lower rod fixed shaft 2, a tightening screw 3 passing through the upper rod fixed shaft 1 and the lower rod fixed shaft 2 in turn, an internally threaded shaft 4 cooperating with the tightened screw 3 and locking pin 5;
[0028] At least one end of the upper rod fixed shaft 1 or the lower rod fixed shaft 2 is located in the lower rod fixed shaft 2 or the upper rod fixed shaft 1, and the upper rod fixed shaft 1 and the lower rod fixed shaft 2 can rotate with each other without axial displacement change , the end of the lower rod fixed shaft 2 away from the tightening screw 3 is also provided with a locking groove 21 that matches the locking pin 5; the upper rod fixed shaft 1 or the lower rod fixed shaft 2 is provided with a spring 6, and the lower rod is fixed A rotation groove 7 is provided on the side wall of the shaft 2; one end of the spring ...
Embodiment 2
[0031] A new shaft structure is provided in this embodiment, such as Figure 1-2 As shown, it includes an upper rod fixed shaft 1, a lower rod fixed shaft 2, a tightening screw 3 passing through the upper rod fixed shaft 1 and the lower rod fixed shaft 2 in turn, an internally threaded shaft 4 cooperating with the tightened screw 3 and Locking pin 5.
[0032] like Figure 3-4 As shown, the side walls of the upper rod fixed shaft 1 and the lower rod fixed shaft 2 are provided with a rotation groove 7, and one end of the upper rod fixed shaft 1 is located in the lower rod fixed shaft 2, and the upper rod fixed shaft 1 is fixed with the lower rod The shafts 2 are mutually rotatable and coaxial, and the other end of the upper rod fixed shaft 1 is located outside the lower rod fixed shaft 2; the same side of the upper rod fixed shaft 1 and the lower rod fixed shaft 2 are equipped with Tighten the through hole of the screw 3, and tighten the screw 3 through one end of the upper ro...
Embodiment 3
[0041] The difference with embodiment 2 in this embodiment is:
[0042] The upper rod fixed shaft 1 is located in the lower rod fixed shaft 2, and the upper rod fixed shaft 1 and the lower rod fixed shaft 2 are provided with a rotation groove 7, the spring 6 is located in the upper rod fixed shaft 1, and one end of the spring 6 is fixed to the upper rod The shaft 1 is fixed, and the other end is fixed with the locking pin 5.
[0043] Other structures are the same as those in Embodiment 2, and will not be repeated here.
