A replacing mechanism 3 is provided at the bottom of the picking mechanism 2, and a connecting column 16 is provided at the bottom of the push plate 15.

[0028] Specifically, the picking mechanism 2 includes a positioning plate 201, which is located inside the empty slot 17 and is clamped to the top of the inner cavity of the empty slot 17. The top of the positioning plate 201 is fixedly connected to the bottom of the connecting column 16. The first spring 203 is fixedly installed on both sides of the bottom of the positioning plate 201, and the bottom of the first spring 203 is fixedly installed with a contact plate 204.

[0029] When the forming block 7 punches the pipe placed inside the forming groove 13, the pipe is squeezed into the inside of the receiving groove 14 during the punching process, and the push plate 15 is received into the inside of the receiving groove 14 under the action of the extrusion force. The push plate 15 drives the connecting column 16 and the positioning plate 201 to move downward, and then the positioning plate 201 squeezes the first spring 203, and the first spring 203 is in a compressed state. After the punching is completed, the forming block 7 is separated from the inside of the forming groove 13, and the push plate 15 is bounced upward under the action of the elastic force of the first spring 203, and then the push plate 15 bounces off the pipe, making it easier for the pipe to separate from the inside of the forming groove 13.

[0030] Specifically, positioning holes 202 are provided on both sides of the top of the positioning plate 201, and positioning rods 205 are fixedly installed on both sides of the top of the inner cavity of the empty slot 17.

[0031] The positioning hole 202 and the positioning rod 205 cooperate with each other to limit the positioning plate 201, thereby improving the stability of the positioning plate 201 when it moves up and down. Under the action of the second spring 207, the storage rod 208 is pushed downward, so that the storage rod 208 drives the circular plate 209 to resist the threaded plate 301, ensuring that the threaded plate 301 will not cause squeezing damage to the bottom of the positioning rod 205 when adjusting its position.

[0032] Specifically, the replacement mechanism 3 includes a threaded plate 301 , which is threadedly connected to the inside of the empty slot 17 . The threaded plate 301 is located at the bottom of the circular plate 209 and abuts against the circular plate 209 .

[0033] The rotating piece 302 facilitates the rotation of the threaded plate 301, and then facilitates the installation of the threaded plate 301 at the bottom of the inner cavity of the empty slot 17 or the removal of the threaded plate 301 from the bottom of the empty slot 17. Under the action of the threaded plate 301, it supports the picking mechanism 2 and facilitates the squeezing of the first spring 203 to ensure the elastic effect of the first spring 203, thereby ensuring the pop-up effect of the pipe fitting.

[0034] Specifically, a threaded barrel 303 is fixedly installed at the bottom of the push plate 15, and the top of the connecting column 16 is threadedly connected to the inside of the threaded barrel 303.

[0035] The groove 304 is used to accommodate the telescopic handle 305. Under the action of the telescopic handle 305, it is easy to rotate the push plate 15, so that the push plate 15 drives the threaded barrel 303 to rotate, and then separates the threaded barrel 303 from the top of the connecting column 16, thereby facilitating the installation and disassembly of the push plate 15, and facilitating the disassembly and replacement of the entire picking mechanism 2 from the bottom of the empty slot 17, thereby ensuring the performance of the picking mechanism 2.

[0036] Specifically, anti-slip grooves 306 are provided on the front and back of the inner cavity of the groove 304 , and anti-slip blocks 307 are fixedly installed on the front and back of the telescopic handle 305 , and the anti-slip blocks 307 are snap-fitted into the interior of the anti-slip grooves 306 .

[0037] The anti-slip groove 306 and the anti-slip block 307 cooperate with each other to limit the telescopic handle 305, preventing the telescopic handle 305 from escaping from the inside of the groove 304, thereby improving the stability of the telescopic handle 305 during use.

[0038] During use, when the forming block 7 punches the pipe placed in the forming groove 13, the pipe is squeezed into the receiving groove 14 during the punching process, and the push plate 15 is received into the receiving groove 14 by the squeezing force, and the push plate 15 drives the connecting column 16 and the positioning plate 201 to move downward, and then the positioning plate 201 squeezes the first spring 203, and the first spring 203 is in a compressed state. After the punching is completed, the forming block 7 is separated from the forming groove 13, and the push plate 15 is pushed upward under the elastic force of the first spring 203, and then the push plate 15 is pushed away from the pipe, so that the pipe can be easily separated from the forming groove 13.

[0039] The rotating piece 302 facilitates the rotation of the threaded plate 301, thereby facilitating the installation of the threaded plate 301 at the bottom of the inner cavity of the empty slot 17 or the removal of the threaded plate 301 from the bottom of the empty slot 17. Under the action of the threaded plate 301, the removing mechanism 2 is supported and the first spring 203 is squeezed to ensure the elastic effect of the first spring 203, thereby ensuring the ejection effect of the pipe fitting.

[0040] The groove 304 accommodates the telescopic handle 305, and the push plate 15 is easily rotated under the action of the telescopic handle 305, so that the push plate 15 drives the threaded barrel 303 to rotate, and then separates the threaded barrel 303 from the top of the connecting column 16, thereby facilitating the installation and disassembly of the push plate 15, and facilitating the disassembly and replacement of the entire picking mechanism 2 from the bottom of the empty slot 17, thereby ensuring the performance of the picking mechanism 2.
