[0023] Specifically, the adjustment assembly 2 includes an adjustment box 21, a limiting structure 22, a bidirectional lead screw 23, an arc-shaped clamping plate 24, and a rotating wheel 25. The adjustment box 21 is located on both sides of the upper end of the base plate 3. The bidirectional lead screw 23 is installed inside the adjustment box 21. A rotating wheel 25 is located at the upper end of the bidirectional lead screw 23. Two sets of arc-shaped clamping plates 24 are installed on the surface of the bidirectional lead screw 23, and the limiting structure 22 is installed on the surface of the arc-shaped clamping plates 24.

[0024] By adopting the above technical solution, rotating the two sets of rotating wheels 25 causes the bidirectional screw 23 to rotate inside the adjusting box 21. The two sets of arc-shaped clamps 24 move synchronously under the limiting action of the limiting structure 22, which can conveniently and accurately clamp and fix the steel bar and the sleeve in the coaxial position with the fixing rod 5, so that the steel bar can be accurately inserted into the sleeve, which plays a good auxiliary fixing effect during connection.

[0025] Specifically, the limiting structure 22 includes a limiting groove 221 and a limiting slider 222. The limiting slider 222 is provided on the surface of the arc-shaped clamping plate 24, and the limiting groove 221 is provided inside the adjusting box 21 at a position corresponding to the limiting slider 222.

[0026] By adopting the above technical solution, the limiting slider 222 moves inside the limiting groove 221, which can play a good limiting effect on the arc-shaped clamp 24, allowing it to move in a straight line.

[0027] Specifically, the limiting structure 22 also includes a ball bearing 223 and a mounting groove 224. The limiting slider 222 has a mounting groove 224 inside, and the ball bearing 223 is disposed inside the mounting groove 224.

[0028] By adopting the above technical solution, the rolling of the ball bearing 223 inside the mounting groove 224 can reduce the friction when the limit slider 222 moves.

[0029] In this embodiment, the base plate 3 is installed in a suitable position, the sleeve is fitted onto the surface of the fixing rod 5, and the scale on its surface is used to measure the sleeve. The positioning plate 7 is moved so that the distance between the stop block and the positioning plate 7 is half the length of the sleeve, and then fixed by the sleeve 6. The magnet 8 connects the sleeve and the positioning plate 7. The reinforcing bar is inserted into a set of adjusting components 2, and the two sets of rotating wheels 25 are rotated so that the bidirectional lead screw 23 rotates in the adjusting box 21. The two sets of arc-shaped clamping plates 24 move synchronously under the limiting action of the limiting structure 22, which can conveniently and accurately clamp and fix the reinforcing bar and the sleeve in the coaxial position with the fixing rod 5, so that the reinforcing bar can be accurately inserted into the sleeve, which plays a good auxiliary fixing effect during connection. The limiting slider 222 moves in the limiting groove 221, which can play a good limiting effect on the arc-shaped clamping plate 24, making it move in a straight line. The rolling ball 223 inside the mounting groove 224 rolls, which can reduce the friction when the limiting slider 222 moves.

[0030] Example 2

[0031] The difference between this embodiment and Embodiment 1 is that the cleaning component 4 includes a mounting plate 41, a cleaning plate 44, and a cleaning brush 45. The mounting plate 41 is provided on both sides of the extruder body 1, the cleaning plate 44 is provided on one side of the mounting plate 41, and the cleaning brush 45 is provided on the surface of the cleaning plate 44.

[0032] By adopting the above technical solution, the cleaning brush 45 on the surface of the cleaning plate 44 inside the mounting plate 41 can wipe and clean the surface of the steel bar and sleeve when they move, keeping the surface clean and avoiding dirt from affecting the quality of the tightening connection.

[0033] Specifically, the cleaning assembly 4 also includes a connecting spring 42 and a telescopic rod 43, wherein a telescopic rod 43 is provided between the mounting plate 41 and the cleaning plate 44, and a connecting spring 42 is provided on the surface of the telescopic rod 43.

[0034] By adopting the above technical solution, the spring 42 connected to the surface of the telescopic rod 43 can generate an elastic thrust on the cleaning plate 44, so that the cleaning brush 45 can adhere to the surface of steel bars and sleeves of different specifications, and the cleaning effect is better.

[0035] In this embodiment, the cleaning brush 45 on the surface of the cleaning plate 44 inside the mounting plate 41 can wipe and clean the surface of the steel bar and sleeve as they move, keeping the surface clean and preventing dirt from affecting the quality of the tight connection. The spring 42 on the surface of the telescopic rod 43 can generate elastic thrust on the cleaning plate 44, allowing the cleaning brush 45 to adhere to the surface of steel bars and sleeves of different specifications, resulting in a better cleaning effect.

[0036] The structure and working principle of the extruder body 1 of this utility model have been disclosed in a sleeve connection device for cold extrusion of threaded steel bars disclosed in Chinese patent application No. 202021389429.1. Its working principle is that the cold press is started to extrude the extrusion mold in the extrusion clamp, so that the steel bar is connected and pressed tightly to the sleeve.

[0037] The working principle and usage process of this utility model are as follows: When using this utility model, the base plate 3 is installed in a suitable position, and the sleeve is fitted onto the surface of the fixing rod 5. The scale on the surface of the sleeve is used for measurement. The positioning plate 7 is moved so that the distance between the stop block and the positioning plate 7 is half the length of the sleeve. Then, it is fixed by the sleeve 6. The magnet 8 connects the sleeve and the positioning plate 7. The reinforcing bar is inserted into a set of adjusting components 2. The two sets of rotating wheels 25 are rotated, causing the bidirectional lead screw 23 to rotate within the adjusting box 21. The two sets of arc-shaped clamping plates 24 move synchronously under the limiting action of the limiting structure 22, which can conveniently and accurately clamp and fix the reinforcing bar and the sleeve in a coaxial position with the fixing rod 5, thereby allowing the reinforcing bar to be accurately... The insertion into the sleeve provides good auxiliary fixing during connection. The limiting slider 222 moves within the limiting groove 221, effectively limiting the arc-shaped clamp 24 and allowing it to move linearly. The rolling balls 223 inside the mounting groove 224 reduce friction during the movement of the limiting slider 222. The cleaning brush 45 on the surface of the cleaning plate 44 within the mounting plate 41 wipes and cleans the surface of the rebar and sleeve as they move, keeping the surface clean and preventing dirt from affecting the quality of the clamping connection. The connecting spring 42 on the surface of the telescopic rod 43 generates elastic thrust on the cleaning plate 44, allowing the cleaning brush 45 to adhere to the surfaces of rebars and sleeves of different specifications, resulting in a better cleaning effect.
