[0028] As shown in Figure 2 The utility model also comprises a support 2, the support 2 is made of insulating material and is fixed on the side wall of the triode body 1, a slot 21 is arranged in the central position of the support 2 and faces downward, two sliding grooves 22 are symmetrically arranged on both sides of the slot 21, the length of the sliding groove 22 is greater than that of the slot 21, the fixed contact 7 is arranged in the slot 21, and the two sliding contacts 8 are arranged in the two sliding grooves 22 respectively, so as to facilitate the contact with the pins and realize the electrical connection.
[0029] As shown in Figure 2As shown, the top of the fixed pin 4 is connected by the plug block and the socket 21, and the plug block is electrically connected with the fixed contact 7. Further, the plug block and the socket 21 can be welded by soldering to improve the stability of the plug-in connection, and the solder covers and wraps to make the electrical connection between the plug block and the fixed contact 7 more stable.
[0030] To ensure the stability of the movable pin 5, two slide rods 3 are arranged, which are fixedly connected with the triode body 1 through the connecting blocks and are located below the bracket 2. The two slide rods 3 are arranged on both sides of the fixed pin 4 and are arranged in line. The connecting blocks for fixing the slide rods 3 are made of insulating material and are arranged independently. The movable pin 5 is provided with a sliding hole 52, which is slidably connected with the slide rod 3.
[0031] Through the sliding cooperation of the slide rod 3 and the sliding hole 52, the movement of the movable pin 5 is guided to make it move linearly along the slide rod 3.

Ensure that the spring sheet 62 is tightly attached to the docking plug 9 to improve the stability of the plug-in, then, use the extension effect of the extended pin 6 to position the triode to the correct position on the circuit board. Ensure that the pins can be easily inserted into the welding point reserved hole, and maintain appropriate distance with other elements of the circuit board, and check whether the triode is stably fixed on the circuit board and whether there is obvious deviation or misplacement between the pins and the welding points, finally, after confirming that the position of the triode is correct, start the welding work. Use appropriate welding tools (such as a welding gun or a welding table) to melt and coat solder between the pins and the welding points to form a firm electrical connection, and after the welding is completed, use appropriate tools (such as scissors or pin clippers) to cut off the excess part of the extended pin 6. Ensure that the length of the cut-off pin is flush with or slightly shorter than the surface of the circuit board to avoid interference with other elements on the circuit board.
[0038] When the triode needs to be recycled for secondary use, first, remove the triode from the original circuit board through the de-welding step, and during de-welding, the cut-off extended pin 6 is pulled out of the docking plug 9 at the same time due to the melting of the solder, and the solder attached thereto is cleaned, and the docking slot 61 of the new complete extended pin 6 is aligned with the docking plug 9 at the bottom of the fixed pin 4 and the movable pin 5 and inserted gently. Ensure that the spring sheet 62 is tightly attached to the docking plug 9 to improve the stability of the plug-in for subsequent use.
