[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, other embodiments obtained by ordinary technicians in this field without making creative work are all within the scope of protection of the present invention.

[0022] Reference Figures 1-4, an interface device of an encoder, comprising an encoder body 1 and a sub-head 8, one side of the encoder body 1 is fixed with a female head 2 by bolts, and the sub-head 8 is inserted into the interior of the female head 2, the outer side of the female head 2 is provided with an external thread, and the outer side of the female head 2 is threaded with an internal thread ring 3 through the external thread, one end of the sub-head 8 is provided with a connecting block 4, the interior of the connecting block 4 is provided with a limiting groove 6, one end of the internal thread ring 3 is integrally formed with a limiting ring 7, and the limiting groove 6 is slidably connected to the limiting ring 7, and a fixing component for limiting the rotation of the internal thread ring 3 is provided on the outer wall of one side of the female head 2, the sub-head 8 is docked with the female head 2, and the female head 2 is located between the internal thread ring 3 and the sub-head 8, and then the internal thread ring 3 is rotated so that the internal thread ring 3 is inserted into the outer side of the female head 2 through the external thread, and then the sub-head 8 enters the interior of the female head 2 to be connected, the internal thread ring 3 moves until the slot 5 is docked with the insertion rod 11 at its top, and then the fixing component is fixed to fix the position of the internal thread ring 3, so that a stable connection is obtained between the female head 2 and the sub-head 8.

[0023] In the present invention, it should be noted that the fixing assembly includes a fixing plate 9, which is fixed to the outer wall of one side of the female head 2 by bolts. A through hole 10 is provided inside the fixing plate 9, and a plug rod 11 is rotatably and slidably connected in the through hole 10. A slot 5 is provided on the top of the internal threaded ring 3, and the plug rod 11 is plugged into the slot 5. By using the plug rod 11 in conjunction with the slot 5, it is convenient for the staff to fix the position of the internal threaded ring 3, so that the female head 2 and the sub-head 8 are further stably connected. The outer side of the plug rod 11 A spring 14 is sleeved, and the two ends of the spring 14 are fixed to the fixed plate 9 and the insertion rod 11 respectively. The spring 14 facilitates the automatic resetting of the insertion rod 11. A fixing ring 13 is welded at the bottom end of the insertion rod 11. The fixing ring 13 can limit the height of the movement of the insertion rod 11 to prevent the insertion rod 11 from moving out of the through hole 10.

[0024] Working principle: When it is necessary to connect the female head 2 and the sub-head 8 on the encoder body 1, first pull the pull block 12 upward to move the insertion rod 11 upward along the through hole 10, and the spring 14 contracts, then dock the sub-head 8 with the female head 2, and at the same time make the female head 2 located between the internal thread ring 3 and the sub-head 8, then rotate the internal thread ring 3 so that the internal thread ring 3 is inserted into the outside of the female head 2 through the external thread, and then the sub-head 8 enters the inside of the female head 2 to be connected, the internal thread ring 3 moves until the slot 5 docks with the insertion rod 11 at its top, release the pull block 12, the spring 14 rebounds and stretches to insert the insertion rod 11 into the through hole 10, thereby fixing the position of the internal thread ring 3, and then the female head 2 and the sub-head 8 are stably connected.

[0025] Furthermore, the terms "installed," "disposed," "connected," and "socketed" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.
