[0032] When it is necessary to fixedly connect the fixture main body 100 with the adjusting seat 201, it is necessary to first press the ranging pointer 401 towards the fixture main body 100, thereby driving the telescopic rod 308 to move along the telescopic rod sliding cavity 204. At this time, the second telescopic spring 311 is in a compressed state. By manually controlling the positioning pin 313 to insert into the pin hole 312, the fixed installation between the positioning fixture 100 and the adjusting seat 201 can be realized.

[0033] The specific implementation method is as follows. The initial positions of the two groups of positioning claws 302 in the positioning claw assembly 300 are at the limit positions where they are opened on both sides. First, the fixture main body 100 is inserted and matched with several steel bars through the positioning card slot 101. The positioning claw assembly 300 on the adjusting seat 201 reaches the position corresponding to the steel bar. By loosening the positioning claw assembly 300, it can laterally clamp the steel bar under the elastic force of the first telescopic spring 203. Then, by starting the piston cylinder 306, the piston rod on the piston cylinder 306 extends to drive the two groups of positioning claws 302 to move on the same side, thereby realizing the clamping and fixing of the steel bar. At this time, through the cooperation of the ranging pointer 401 and the scale 400, the corresponding position can be obtained through the ranging pointer 401. At this time, press the ranging pointer 401 towards the fixture main body 100, thereby driving the telescopic rod 308 to move along the sliding cavity. At this time, the second telescopic spring 311 is in a compressed state. By manually controlling the positioning pin 313 to insert into the pin hole 312, the fixed installation between the positioning fixture 100 and the adjusting seat 201 can be realized, achieving accurate ranging and positioning of the steel bar, and effectively improving the positioning accuracy of the steel bar.

By adjusting the sliding of the telescopic rod 308, the adjusting seat 201 can be automatically telescopically adjusted under the action of the first telescopic spring, and accurate positioning of the steel bar can be realized, improving the convenience and accuracy during use.

[0036] The specific implementation is as follows. The initial positions of the two groups of positioning claws 302 in the positioning claw assembly 300 are at the extreme positions of being opened on both sides. First, the fixture main body 100 is inserted and matched with several steel bars through the positioning card slots 101. The positioning claw assembly 300 on the adjusting seat 201 is moved to the position corresponding to the steel bars. The ranging pointer 401 is pressed towards the fixture main body 100, thereby driving the telescopic rod 308 to move along the sliding cavity.

By manually controlling the positioning pin 313 to be inserted into the pin hole 312, the fixed installation between the positioning fixture 100 and the adjusting seat 201 can be realized. At the same time, during this process, the pulling rope 502 is always tightened under the action of the first telescopic spring 203. The adjusting seat 203 moves gradually towards the steel bar under the elastic force of the first telescopic spring 203 until it is transversely clamped. Then, by starting the piston cylinder 306, the piston rod on the piston cylinder 306 extends to drive the two groups of positioning claws 302 to move on the same side, thereby realizing the clamping and fixing of the steel bars. At this time, through the cooperation of the ranging pointer 401 and the scale 400, the corresponding position can be obtained through the ranging pointer 401.
