[0020] The utility model provides a technical solution: Figure 1 , Figure 2 and Figure 3 As shown, in the present embodiment, a slide transmission mechanism for a threading machine comprises a symmetrically arranged mounting seat 1, a fixing rod 2 is installed between the two mounting seats 1, a mounting sleeve 3 is sleeved on the outside of the fixing rod 2, a fixing box 4 is fixed on one end of the bottom end surface of the mounting sleeve 3, a transmission gear 7 is arranged inside the fixing box 4, a connecting tooth groove 6 is evenly provided on the bottom surface of the fixing rod 2, the transmission gear 7 is meshed and connected with the connecting tooth groove 6, a handle 5 is arranged on the outside of the fixing box 4, one end of the handle 5 is connected to the transmission gear 7, a first functional component is arranged on the inner bottom of the fixing box 4, the first functional component comprises an oil storage box 8 arranged on the inner bottom of the fixing box 4, a through groove 9 is provided on the bottom of one side surface of the fixing box 4 for the oil storage box 8 to penetrate, and a limited A positioning pull plate 10 is provided, and a fixing groove 12 is provided at the bottom of the inner wall of one side of the fixing box 4. A connecting spring 13 is fixed inside the fixing groove 12. One end of the connecting spring 13 is fixedly connected to the other end surface of the oil storage box 8. The other end surface of the oil storage box 8 is symmetrically provided with an anti-collision strip 14. The surface of the anti-collision strip 14 is bonded and connected to the surface of the oil storage box 8. A limiting mesh plate 11 is provided inside the oil storage box 8. The surface width of the limiting mesh plate 11 is equal to the width of the opening of the oil storage box 8. The cross-section of the limiting mesh plate 11 is arc-shaped. There is a gap between the bottom surface of the transmission gear 7 and the middle surface of the limiting mesh plate 11, which is convenient for adding lubrication to the transmission gear 7, so that the friction force when the transmission gear 7 is meshed with the connecting tooth groove 6 is reduced, the functionality is improved, and the practicality is better.

[0021] like Figure 2 and Figure 4As shown, a second functional component is provided at the end of the mounting sleeve 3, and the second functional component includes a mounting snap ring 15 symmetrically arranged at both ends of the mounting sleeve 3, a sponge strip 17 is provided on the inner side of the mounting snap ring 15, and the top end surface of the sponge strip 17 is bonded and connected to the inner top surface of the mounting snap ring 15, and the outer surfaces of both ends of the mounting sleeve 3 are symmetrically provided with connecting grooves 16 for one side of the mounting snap ring 15 to engage, and balls 18 are equidistantly installed on the inner top surface of the mounting sleeve 3, and the surface of the ball 18 is rollingly fitted with the surface of the fixing rod 2, the end cross-section of the mounting snap ring 15 is inverted "L" shape, and the side longitudinal section of the mounting snap ring 15 is semi-ring-shaped, and the bottom end surface of the sponge strip 17 is fitted and connected with the surface of the fixing rod 2, so that the mounting sleeve 3 can achieve the purpose of cleaning the surface of the fixing rod 2 during the movement, and can reduce the friction force generated during the movement of the mounting sleeve 3, which is convenient for reducing friction damage and has a good practical effect.

[0022] The utility model provides a slide transmission mechanism for a threading machine, and the specific working principle is as follows: when it is necessary to add lubricating oil to the transmission gear 7 inside the fixed box 4 for lubrication, the utility model first pulls the limit pull plate 10 so that the limit pull plate 10 drives the oil storage box 8 to move to the outside of the fixed box 4 through the through groove 9. At this time, the connecting spring 13 inside the fixed groove 12 will be stretched and generate a rebound force. Until the oil storage box 8 moves to the outside of the fixed box 4 to a suitable distance, the worker can inject lubricating oil into the oil storage box 8 until the lubricating oil exceeds the surface of the limit mesh plate 11 inside the oil storage box 8, and then the oil storage box 8 can be pushed to move to the inside of the fixed box 4. At the same time, the rebound force generated by the connecting spring 13 acts on the oil storage box 8, so that the oil storage box 8 can rebound and reset, and when the transmission gear 7 inside the fixed box 4 rotates, the bottom surface of the transmission gear 7 will contact with the lubricating oil inside the oil storage box 8, so that the surface of the transmission gear 7 can achieve the purpose of lubrication. The utility model is convenient for reducing the friction force when the transmission gear 7 is meshed with the connecting tooth groove 6 on the bottom surface of the fixing rod 2, the functionality is improved, and the practicality is better; when the second functional component is installed in the early stage of the utility model, the sponge strip 17 is first pushed to move toward the inner surface of the mounting clamp ring 15, so that the surface of the sponge strip 17 is bonded and connected with the inner top surface of the mounting clamp ring 15, and then the mounting clamp ring 15 is pushed to move toward the two ends of the fixing box 4, so that one side of the mounting clamp ring 15 can be limited and engaged to the inside of the connecting groove 16, so that the surface of the sponge strip 17 can be fitted and connected with the surface of the fixing rod 2. When the sleeve 3 is installed outside the fixing rod 2 in the later stage, the sponge strip 17 can clean the impurities attached to the surface of the fixing rod 2, and at the same time, the surface of the ball 18 on the inner top of the sleeve 3 is rolled and fitted with the surface of the fixing rod 2, so that the friction force when the mounting sleeve 3 moves outside the fixing rod 2 is reduced, which is convenient for improving the movement efficiency of the mounting sleeve 3, and the practical effect is better.
