The beneficial effects of the present invention are:

One is that the external terminals at both ends of the quick multi-purpose connector of the present invention have a round tube pin fixed pipe connection and a hinge mechanism, so the external terminals can well adapt to the connection between two movable components (components to be connected) For the purpose of quickly adjusting the stable distance between the two, and can reliably transmit and bear the pressure and tension between the two movable components, so as to achieve the purpose of stability. Due to the different distances and cross-sectional shapes of the components to be fixed, the external terminal can also be extended through the corresponding accessories.

Second, the quick multi-purpose connector of the present invention can be used for the combination of different components in space, has strong adaptability, and can be mixed with existing different assemblies (such as fasteners). The adjustment is performed through the forward and reverse threads on the screw rod, the adjustment speed is fast, the adjustment range is large, and the bearing is reliable, the bearing capacity is strong, and the operation is simple. It can be used as a receiving and pressure-bearing connection. It can be used for temporary facility projects such as formwork erection in building construction and connection in other daily industries and civil life.

The third is that the quick multi-purpose connector of the present invention belongs to a multi-purpose connecting tool that can be standardized in multiple specifications and industrialized. It can be industrialized with low production cost, is easy to use, saves labor, saves resources in long-term construction, and has no pollution from leftovers.

Detailed ways

In order to make the technical solution and technical effect of the present invention more obvious and easy to understand, the following will be described in detail in conjunction with the accompanying drawings.

As shown in FIG. 1 and FIG. 2 , the quick multi-purpose connector of the present invention mainly includes: a screw rod 1 , two nuts 2 and two external terminals 3 .

As shown in FIG. 1 and FIG. 2 , the middle part of the screw 1 has an operation hole 4 and/or an operation surface for driving the screw 1 to rotate; the left half and the right half of the screw 1 have opposite screw threads. The two nuts are respectively screwed on the left half and the right half of the screw rod. When the screw is turned, the two nuts can move to the middle of the screw or move to both ends of the screw at the same time.
