However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figures 1-4 As shown, the utility model provides a new type of stainless steel lined external thread internal connecting pipe fitting, including a connecting part 1, connecting grooves 2 are provided at both ends of the outside of the connecting part 1, a connecting head 3 is slidably installed inside the connecting groove 2, a threaded sleeve 4 is fixedly installed on the outer wall of the connecting head 3, a clamping groove 7 is provided on the top and bottom of the connecting head 3, a limiting groove 8 is provided on the top and bottom surfaces of the inner part of the connecting groove 2, a spring 9 is fixedly installed on the inner wall of the limiting groove 8, a clamping block 10 is fixedly installed on the end of the spring 9 close to the connecting groove 2, an opening 11 is opened through the inner wall of the limiting groove 8, a pull plate 12 is fixedly installed on the end of the clamping block 10 close to the opening 11, and the pull plate 12 is slidably connected to the opening 11.

[0024] The effect achieved by the entire embodiment 1 is that when the threads on the threaded sleeve 4 are worn, the staff pulls the pull plate 12, and the pull plate 12 drives the block 10 to move, so that the block 10 leaves the slot 7. At this time, the staff can remove the connecting head 3, replace the new connecting head 3, and insert the connecting head 3 into the connecting groove 2. When the connecting head 3 contacts the inclined surface of the block 10, the connecting head 3 pushes the block 10 to move, so that the block 10 enters the limit groove 8, and the spring 9 is compressed. When the connecting head 3 completely enters the connecting groove 2, the block 10 enters the slot 7 under the elastic force of the spring 9. At this time, the connecting head 3 is fixed, and the replacement can be completed, which reduces the cost of use.

[0025] Example 2, as Figures 1-4 As shown, further, a storage groove 13 is provided on the inner wall of the opening 11, and a fixed plate 14 is fixedly installed on the inner wall of the storage groove 13. A first bevel gear 17 is rotatably installed on one end of the fixed plate 14, and a threaded rod 16 is fixedly installed on one end of the first bevel gear 17 close to the fixed plate 14. One end of the threaded rod 16 passes through the fixed plate 14, and a support plate 15 is slidably installed inside the storage groove 13. A threaded hole 22 is provided on the end of the support plate 15 close to the threaded rod 16, and the threaded rod 16 is threadedly connected to the threaded hole 22.

[0026] Furthermore, a rotating shaft 18 is rotatably installed through the top surface of the storage tank 13 , a handle 20 is fixedly installed on the top of the rotating shaft 18 , and a second bevel gear 19 is fixedly installed on the bottom of the rotating shaft 18 , and the first bevel gear 17 is meshed with the second bevel gear 19 .

[0027] Furthermore, a limiting ring 21 is fixedly mounted on the outer wall of the rotating shaft 18 , the bottom of the handle 20 is in contact with the outer wall of the connecting member 1 , and the top of the limiting ring 21 is in contact with the inner wall of the storage groove 13 .

[0028] Furthermore, a sealing groove 5 is opened on the inner wall of the connecting groove 2, and a sealing ring 6 is fixedly installed on the inner wall of the sealing groove 5 to further enhance the sealing performance.

[0029] Furthermore, the outer wall of the connector 3 fits in with the inner wall of the connecting groove 2 , and the outer wall of the clamping block 10 fits in with the inner wall of the clamping groove 7 . When the clamping block 10 enters the clamping groove 7 , the connector 3 is fixed and will not shake.

[0030] Furthermore, the outer wall of the abutment plate 15 fits against the inner wall of the storage slot 13 to prevent the abutment plate 15 from rotating when the threaded rod 16 rotates.

[0031] The effect achieved by the entire embodiment 2 is that when the installation of the connecting head 3 is completed, the staff rotates the handle 20, and the handle 20 drives the second bevel gear 19 to rotate through the rotating shaft 18, so that the second bevel gear 19 drives the first bevel gear 17 to rotate, and the threaded rod 16 rotates. At this time, since the threaded hole 22 is threadedly connected to the threaded rod 16, the push plate 15 enters the inside of the opening 11 along the storage groove 13. At this time, the push plate 15 can fix the pull plate 12 to prevent it from moving, thereby improving stability.

[0032] When the screw thread on the threaded sleeve 4 is worn, the staff rotates the handle 20, and the handle 20 drives the second bevel gear 19 to rotate through the rotating shaft 18, so that the second bevel gear 19 drives the first bevel gear 17 to rotate, and the threaded rod 16 rotates. At this time, since the threaded hole 22 is threadedly connected with the threaded rod 16, the stop plate 15 enters the storage slot 13 along the storage slot 13. Then the staff pulls the pull plate 12, and the pull plate 12 drives the block 10 to move, so that the block 10 leaves the slot 7. At this time, the staff can remove the connector 3 and replace it with a new connector 3. Insert the connector 3 into the connecting groove 2. When the connector 3 contacts the inclined surface of the block 10, the connector 3 pushes the block 10 to move, so that the block 10 enters the limit groove 8, and the spring 9 is compressed. When the connector 3 is completely entered into the connecting groove 2, the block 10 enters the slot 7 under the elastic force of the spring 9. At this time, the connector 3 is fixed, and the replacement can be completed, which reduces the cost of use. When the installation of the connector 3 is completed, the staff rotates the handle 20, and the handle 20 drives the second bevel gear 19 to rotate through the rotating shaft 18, so that the second bevel gear 19 drives the first bevel gear 17 to rotate, and the threaded rod 16 rotates. At this time, since the threaded hole 22 is threadedly connected to the threaded rod 16, the push plate 15 enters the inside of the opening 11 along the storage groove 13. At this time, the push plate 15 can fix the pull plate 12 to prevent it from moving, thereby improving stability.
