Embodiment 1
[0027] Such as figure 1 and figure 2 As shown, an automatic adjustable connecting piece with upper screw and lower lock includes an upper connecting rod 1 and a lower connecting rod 2. The ends of the upper connecting rod 1 and the lower connecting rod 2 have an upper connecting cavity 3 and a lower connecting rod respectively. Cavity 4, preferably, the outer wall of upper connecting cavity 3 and lower connecting cavity 4 is inflated, which is convenient for making and connecting, and there are internal threads in upper connecting cavity 3 and lower connecting cavity 4, and the internal screw of described upper connecting rod 1 Connected with a plug-in rod 5, the lower connecting rod 2 is internally screwed with a clamping mechanism 7, the outer wall of the plug-in rod 5 has a ring gear 6 integrally formed with the plug-in rod 5, when the plug-in rod 5 is inserted into the card When in the connecting mechanism 7, rotating the ring gear 6 can adjust the position of the end of...
Embodiment 2
[0036] The structure and working principle of this embodiment are basically the same as that of Embodiment 1, the difference is that, as image 3 and Figure 4 As shown, the end of the insertion rod 5 has a step-shaped clamping platform 9, and the clamping mechanism 7 includes a spring assembly 14 screwed to the lower connection chamber 4. When the insertion rod 5 is inserted into the spring assembly 14 At this time, rotating the ring gear 6 can make the card table 9 close to the spring assembly 14 and make the card table 9 and the end of the spring assembly 14 form a snap fit. Since the structure of the shrapnel assembly 14 is relatively simple, it is easy to assemble and use.
[0037] combine Figure 6 As shown, the shrapnel assembly 14 includes a shrapnel threaded portion 15 that is threadedly engaged with the lower connection chamber 4 , and the end of the shrapnel threaded portion 15 is provided with a number of springs evenly distributed along the axial direction of th...
