In order to achieve the above purpose, the present invention provides the following technical solutions: a screw connecting rod includes a rod body, a male connection, a female connection, a steel belt, a tensioning mechanism and a through groove, and the end of the rod body is provided with a male connection end, and the One end of the rod body away from the male end is internally provided with a female connection, the outside including the rod body is provided with a steel belt, the outer side of the steel belt is provided with a through groove, and a tensioning mechanism is fixed between the steel belt and the rod body.

Preferably, the tensioning mechanism includes a fixing slot, an adjusting nut and a screw rod, there are two fixing slots in total, and the two fixing slots are respectively fixed on the rod body and the steel belt, and the two fixing slots are The openings are opposite to each other, and two ends of the adjusting nut are respectively provided with a screw rod, the screw threads of the two screw rods are opposite, and the screw rods are screwed with the fixing groove.

Preferably, several tensioning mechanisms are provided, and they are provided on the inner side of the steel belt at equal distances.

Preferably, the through grooves are equidistantly distributed on the outside of the steel strip, and the through grooves are parallel to the diameter lines of the through grooves.

Compared with the prior art, the beneficial effect of the present invention is that: the screw connecting rod, which is convenient for adjusting the tension of the steel belt, rotates the adjusting nut to make the screws at both ends engage in the inside of the fixing groove, so as to adjust the tension between the steel belt and the rod body. Since the total length of the steel belt is unchanged, the total length of the tensioning mechanism has changed, so the tensioning degree of the steel belt will be adjusted to a certain extent, so as to achieve the purpose of adjusting the tensioning degree, which is easy to use. At the same time, the arrangement of the through groove can play a certain guiding role in the excavation process of the device, thereby further reducing the obstruction of minerals.
