Description

Rebar retaining device Technical Field The utility model relates to the technical field of reinforcement retaining, in particular to a reinforcement retaining device. Background The steel bar refers to steel for reinforced concrete and prestressed reinforced concrete, and the cross section of the steel bar is round, and sometimes square with round corners. Including smooth round bars, ribbed bars, twisted bars. In the processing processes of sampling, straightening and the like, the head of the steel bar coil wound on the winding shaft is required to be pulled out from the coil to be cut off and sampled or guided into corresponding equipment to be processed, the process is generally operated by bare hands, certain force is required to be applied to control the elasticity of the steel bar due to the rigidity of the steel bar, at the moment, other operations are required to be matched, the independent operation is slightly careless, and the steel bar which is out of control can be withdrawn and bounced back due to the rigidity, so that potential safety hazards exist. The utility model discloses a steel bar retaining device disclosed in Chinese patent application publication No. CN212581170U, which comprises a retaining box and a winding shaft, wherein the top and the bottom of one side of the retaining box are respectively provided with a fixed pipe, the top of the inner cavity of the retaining box is provided with a spring, the bottom of the spring is fixedly connected with a pressing plate, one side of the retaining box is provided with a retaining window in a penetrating way, and the retaining window is positioned below the pressing plate. The steel bar retaining device solves the problem that the existing steel bars in a rolling mode are easy to retract to hurt people due to elasticity when a part of the steel bars are required to be pulled out for use or processed, and can be lowered by rotating the screw rod when the steel bars are not required to be pulled forward, so that the pressing plate does not have supporting force to lower under the action of the spring to hold the steel bars in the inner cavity of the retaining window, and therefore one end of the rolled steel bars is effectively prevented from being rebounded due to rolling elasticity when the rolled steel bars are deformed for use for a long time, and the injury to people due to rebounded spring is avoided. In view of the above-mentioned related art, the inventors considered that there is a disadvantage in that the above-mentioned device drives the pressing plate to move downward and abut against the upper surface of the reinforcing bar by driving the threaded rod to rotate, thereby keeping the reinforcing bar stable. In actual use, because the surface of reinforcing bar is provided with the transverse rib, supports tight transverse rib when the clamp plate moves down, because platelike clamp plate and the area of contact of transverse rib are limited, the clamp plate is limited to the spacing effect of reinforcing bar, and the reinforcing bar easily takes place relative slip with the clamp plate under the effect of external force this moment, uses and experiences poorly. Disclosure of utility model In order to solve the problems, the utility model provides a steel bar retaining device. The technical aim of the utility model is achieved through the following technical scheme that the steel bar retaining device comprises a sleeve, a fixed pipe and a retaining box, wherein the sleeve is arranged on a rolling shaft, the fixed pipe is connected with the sleeve, the retaining box is arranged on the fixed pipe, a retaining window is arranged on the side wall of the retaining box in a penetrating mode, a thread groove is formed in the bottom surface of the retaining box, a threaded rod is connected with the thread groove in a threaded mode, a sliding groove communicated with the thread groove is formed in the inner wall of the retaining window, a pressing plate is arranged in the sliding groove in a sliding mode, the bottom surface of the pressing plate is connected with the threaded rod in a rotating mode, and an auxiliary assembly used for assisting in fixing of steel bars is arranged on the pressing plate. Through adopting above-mentioned technical scheme, the reinforcing bar of winding on the take-up shaft coils in processing processes such as sample, straightening, and its head need pull out from coiling and cuts off the sample or guide in corresponding equipment and process, and the staff need pull the head of reinforcing bar and make the head of reinforcing bar pass the stopping window this moment, and the threaded rod is rotated, can make the clamp plate move down and support the rib on the reinforcing bar under the effect of threaded rod to make the reinforcing bar preliminary remain stable. Further, the staff only needs to open the auxiliary assembly, the loop bar can be enabled to move downwards continuously and be clamped between the tw
