In order to achieve the purpose, the invention provides the following technical scheme: the screw connecting rod comprises a rod body, a male joint, a female joint, a steel belt, a tensioning mechanism and a through groove, wherein the male joint end is arranged at the end part of the rod body, the female joint is arranged inside one end, away from the male joint end, of the rod body, the steel belt is arranged outside the rod body, the through groove is formed in the outer side of the steel belt, and the tensioning mechanism is fixed between the steel belt and the rod body.

Preferably, straining device includes fixed slot, adjusting nut and screw rod, the fixed slot is provided with two altogether, and two the fixed slot is fixed respectively on the body of rod and steel band, and two the fixed slot opening is relative, adjusting nut both ends are provided with a screw rod respectively, and two the screw rod is opposite the screw thread of screw rod, moreover the screw rod with fixed slot threaded connection.

Preferably, the tensioning mechanisms are arranged in a plurality of numbers and are arranged on the inner side of the steel belt at equal intervals.

Preferably, the through grooves are equidistantly distributed on the outer side of the steel belt, and the through grooves are parallel to the radial line of the through grooves.

Compared with the prior art, the invention has the beneficial effects that: this screw connecting rod convenient to adjust steel band rate of tension makes the screw rod at both ends carry out the meshing motion in the fixed slot inside through rotating adjusting nut, thereby adjust the interval between the steel band and the body of rod, because the total length of steel band is unchangeable, straining device's total length has changed, therefore the degree of tension of steel band just can obtain certain regulation, thereby realize adjusting the purpose of degree of tension, and convenient to use, the setting that leads to the groove simultaneously can play certain guide effect at the in-process that the device was tunneled, and then can further reduce the hindrance of mineral.
