[0039] In summary: when using the portable angle iron punching fixture, first use the universal wheels 2 at the bottom to easily move the fixture to the appropriate position for operation. Then start the motor 8, which will drive the bidirectional screw 903 to start rotating. In this process, the two moving blocks 902 on the bidirectional screw 903 will move synchronously to both sides, and the connecting rod 905 will move together. Through the precise cooperation of the connecting rod 905 and the movable piece 904, the carrying plate 7 and all the parts installed on its top will be smoothly pushed out of the box body 1, preparing for the next angle iron punching operation. Next, place the angle iron to be processed in the groove of the base 10 on the top of the carrying plate 7, ensuring the accurate position of the angle iron. At this time, pull up the pull rod 110209 at the top of the moving block 1102. This action will separate the pull rod 110209 at the bottom from the gear two 110207, thereby releasing the locking of the rotating rod 110204. Then, rotate the handle 1103, which will rotate the rotating rod 110204 and the gear one 110203 and gear two 110207 installed on it. Since the gear one 110203 is in close engagement with the rack 110202, the rotation of the gear one 110203 will drive the rack 110202 and the push plate 1106 installed at the bottom to move downward. During the movement of the push plate 1106, it will push the push rod 1104 and the clamp block 1105 to move downward together until the angle iron is clamped tightly. At this time, release the pull rod 110209, and the spring 110208 will quickly rebound, pushing the bottom of the pull rod 110209 to re-engage with the gear two 110207, thereby locking the rotating rod 110204 to ensure that the push plate 1106 and the clamp block 1105 remain in the current position. When the punching operation is completed, pull up the pull rod 110209 again, and the tension spring 110206 will rebound and drive the limit rod 110205 and the push plate 1106, push rod 1104, and clamp block 1105 installed at the bottom to return to the original position. Then, control the motor 8 to start again to drive the bidirectional screw 903 to rotate in the opposite direction. Through the cooperation of the moving blocks 902, connecting rod 905, and movable piece 904, the carrying plate 7 and the parts on its top will be smoothly retracted into the box body 1.

[0040] Advantages:

[0041] The portable angle iron punching fixing clamp, through the design of the lifting mechanism, when the clamp needs to be used, only the motor needs to be started, the motor will drive the bidirectional bolt to rotate, and then drive the two moving blocks to move synchronously to both sides. During this process, the clever cooperation of the connecting rod and the movable piece enables the carrying plate to be smoothly pushed out from the inside of the box. After the work is completed, the motor is started again, and the moving block, the connecting rod and the movable piece will work together to smoothly retract the carrying plate into the inside of the box for carrying. Through the design of the moving block, when operating, the user only needs to pull the pull rod upward slightly, at which time the spring will be compressed, the tooth groove at the bottom of the pull rod and gear two are separated from each other, thereby releasing the locking of the rotating rod. Subsequently, the rotating handle is rotated, and the rotating handle will drive the rotating rod, gear one and gear two to rotate together. Since gear one is closely meshed with the rack, this rotating action will push the push plate to slide downward along the fixed path. During the sliding process of the push plate, the push plate will push the push rod, and then accurately push the clamping block to the surface of the angle iron, so as to realize the stable clamping of the angle iron. When the position of the rotating rod needs to be fixed to ensure that the push plate remains in the current state, the user only needs to release the pull rod. At this time, the spring will rebound quickly, the tooth groove at the bottom of the pull rod is closely meshed with gear two again, thereby effectively locking the rotating rod to prevent accidental movement thereof.
