Background
The connecting rod is a coaxial stock that connects into for special needs for two sections poles, fixes some utensils, sets up and uses in specific occasion combination through the connecting rod, but the length of current connecting rod is difficult for the adjustment, and length is fixed, and some occasions can't be installed, uses and inconvenient and connect insecure, and the connection position is not hidden etc..
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, the utility model provides a double flat head invisible threaded connecting rod; the connecting rod can be used for selecting the length according to the use condition, is convenient to use and simple to install, and can hide the connecting part.
In order to realize the technical purpose, reach above-mentioned technological effect, the utility model discloses a realize through following technical scheme:
the double-flat-head invisible threaded connecting rod comprises a screw rod and a nut rod; the screw rod is a cylindrical rod with a threaded rod arranged at the front end, and the diameter of the threaded rod is smaller than that of the cylindrical rod; the nut rod is a cylindrical rod, and one end of the nut rod is provided with an axial internal thread hole; the length of the threaded rod is smaller than the depth of the internal threaded hole, the internal threaded hole is matched with the threaded rod, and the threaded rod is hidden in the internal threaded hole; the diameters of the threaded ends of the screw rod and the screw cap rod are smaller than those of the other ends of the screw rod and the screw cap rod; the screw rod and the nut rod are respectively provided with different lengths of 0.5cm-20cm, the lengths are sequentially increased by 0.5cm, and different connecting rods are formed by matching different screw rods and nut rods.
Furthermore, a cross-shaped groove is formed in the tail end of the screw rod, and a cross-shaped groove is formed in the tail end of the nut rod; the cross-shaped groove is suitable for fixing the plum blossom screwdriver.
Further, the diameters of the lead screw and the nut rod are set to be different specifications of 4, 6, 8 and 10 mm.
The utility model has the advantages that: the double flat head invisible threaded connecting rod has the following advantages:
1. the screw rod and the nut rod are arranged and can be connected through threads, the threaded rod is hidden in the internal threaded hole and is connected through threads, connection is reliable, and use is convenient.
2. The screw rod and the threaded rod can be matched into different lengths from 1cm to 20cm from 0.5cm to 10cm in different lengths, the lengths are sequentially increased by 0.5mm, different lengths can meet different requirements, and different lengths are convenient to select.
Of course, it is not necessary for any particular product to achieve all of the above-described advantages at the same time.
