Coupling assembling 40 is provided with two, two coupling assembling 40 all include electric putter II 410 and fixed block 420 and the pressure head 430 that sets up in pairs, two fixed blocks 420 are connected to support 330 upper surface both sides respectively, and two sets of holders 320 all set up about two fixed block 420 symmetries, two electric putter II 410's stiff end and movable end are connected with corresponding fixed block 420 and pressure head 430 respectively, two pressure heads 430 are with the pressfitting of reinforcing bar I10 and reinforcing bar II 20 after the bonding.

In this embodiment, the connection method of the steel bar i 10 and the steel bar ii 20 is as follows:

step S1: clamping and gluing, namely respectively clamping and fixing the steel bar I10 and the steel bar II 20 by sequentially utilizing two groups of four clamping pieces 320, and spraying an adhesive on the opposite arc surfaces of the steel bar I10 and the steel bar II 20 clamped by the four clamping pieces 320 by using a gluing gun;

in specific setting, during the operation of the clamping member 320 in step S1, the steel bar i 10 and the steel bar ii 20 are respectively placed inside the corresponding U-shaped clamp 322, and then the end of the locking bolt 323 is extended into the U-shaped clamp 322 by using the threaded hole, so that the steel bar i 10 and the steel bar ii 20 are tightly pressed between the inner bottom of the U-shaped clamp 322 and the end of the locking bolt 323.

Step S2: straightening and attaching, namely moving two clamping pieces 320 in two opposite thread directions towards a direction away from each other by using two bidirectional driving pieces 310, indirectly straightening or straightening a clamped steel bar I10 and a clamped steel bar II 20, starting two synchronously operated electric push rods I340 to drive a slide block I350 connected with the electric push rods I to move in a corresponding slide rail I, indirectly enabling the two bidirectional driving pieces 310 to be close together, and enabling opposite arc-shaped surfaces of the steel bar I10 and the steel bar II 20 to be contacted and adhered by using an adhesive;

during specific setting, in the operation process of the two bidirectional driving elements 310 in step S2, the two servo motors 311 are sequentially started to drive the corresponding bidirectional screws 312 to rotate, so as to drive the two ball screw nut pairs 313 on each bidirectional screw 312 to move in the opposite direction, and indirectly straighten the steel bars i 10 and the steel bars ii 20 clamped by the clamping members 320 to be in the horizontal straight state, wherein the two servo motors 311 respectively drive the corresponding bidirectional screws 312 to rotate, so that the two ball screw nut pairs 313 connected in pairs on the two bidirectional screws 312 indirectly drive the two clamping members 320 to move in the opposite direction, so that the steel bars i 10 and the steel bars ii 20 are straightened to be in the horizontal straight state, and the subsequent two bidirectional driving elements are conveniently bonded and extruded and connected.

Step S3: compress tightly the connection, start two synchronous operation's II 410 of electric putter and drive the pressure head 430 that connects and draw close, two pressure heads 430 carry out extrusion deformation with the reinforcing bar I10 and the reinforcing bar II 20 after the contact adhesion, indirectly make two reinforcing bars I10 and the reinforcing bar II 20 large tracts of land stick admittedly, treat the adhesive solidification back, loosen pressure head 430 and respectively with two-way driving piece 310, at last will connect reinforcing bar I10 and reinforcing bar II 20 after lift off from four holders 320.

It should be noted that the specific model specifications of the servo motor 311, the electric push rod i 340, the electric push rod ii 410, the locking bolt 323, and the bidirectional screw 312 need to be determined by model selection according to the actual specification of the device, and the specific model selection calculation method adopts the prior art in the field, so detailed description is omitted.
