The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] See also Figures 1-6 , shows a schematic structural diagram of a pipe threading tool in one embodiment of the present invention, which includes a pipe threading mandrel 100 and a base 200, with the pipe threading mandrel 100 mounted on the base 200. The pipe threading mandrel 100 includes a first shaft segment 110 and a second shaft segment 120 disposed at one end of the first shaft segment 110. The diameter of the first shaft segment 110 is larger than the diameter of the second shaft segment 120. A connecting portion 111 is disposed at the other end of the first shaft segment 110, and the base 200 is disposed at the connecting portion 111. A baffle 112 is disposed at the end where the first shaft segment 110 and the second shaft segment 120 are connected. A sleeve gap a is defined between the baffle 112 and the second shaft segment 120. The sleeve gap a is used to accommodate at least a portion of the hose 10, so that the baffle 112 shields at least a portion of the outer surface of the hose 10.

[0033] See also Figure 5 and Figure 6 During use, the protective cover 20 that needs to be put on the outside of the hose is put on the first shaft section 110, and the hose 10 is put on the second shaft section 120, and all the markings 30 on the hose 10 are ensured to be blocked by the blocking piece 112. Move the protective cover 20 to the side close to the hose 10 and put the protective cover 20 on the appropriate position of the hose 10 to complete the pipe threading operation, and then remove the hose 10 with the protective cover 20.

[0034] The above-mentioned pipe threading tool is provided with a first shaft section 110 and a second shaft section 120 of different diameters, which are respectively used to sleeve the hose 10 and the protective sleeve 20, and a baffle 112 is provided at the end of the first shaft section 110. The baffle 112 can cover all the markings 30 on the hose 10 to play an isolation role between the protective sleeve 20 and the hose 10, protect the markings 30 on the hose 10, reduce the risk of defects, and thus produce high-efficiency, low-cost, high-quality hose products.

[0035] See also Figure 1 、 Figure 2 and Figure 3 In one embodiment, the baffle 112 includes an arc-shaped baffle 112 a , and an outer surface of the arc-shaped baffle 112 a is flush with an outer surface of the first shaft segment 110 .

[0036] In one embodiment, the connecting portion 111 includes a connecting rod 111 a .

[0037] In one embodiment, the base 200 includes a rectangular counterweight 200a. When in use, the counterweight 200a is placed on the ground or a workbench, and the pipe threading mandrel 100 is tilted and stands above the ground or the workbench, so as to facilitate the pipe threading operation and be more stable and reliable.

[0038] See also Figure 4 、 Figure 5 and Figure 6 In another embodiment, the connecting portion 111 includes a connecting plate 111b.

[0039] In another embodiment, the base 200 includes a counterweight plate 200b disposed perpendicular to the connecting plate 111b. When in use, the counterweight plate 200b is placed on the ground or a workbench, and the pipe threading mandrel 100 is tilted and stands above the ground or workbench, facilitating the pipe threading operation and providing greater stability and reliability.

[0040] See also Figure 7-11 In one embodiment, a slot 113 is provided on the end of the first shaft segment 110 connected to the second shaft segment 120, and the baffle 112 has an insertion end 1121 that cooperates with the slot 113, and the insertion end 1121 is detachably fixed in the slot 113 through an embedded connector 1122.

[0041] In some embodiments, the baffle 112 includes multiple pieces, and the insertion end 1121 of each baffle 112 cooperates with the slot 113. Different baffles 112 have different sizes of parts forming the sleeve gap a. During use, the appropriate baffle 112 can be selected according to the position and size of the imprint mark 30 of the hose, and the insertion end 1121 of the baffle 112 is inserted into the slot 113 and fixed by the embedded connector 1122. There is a sleeve gap a between the baffle 112 and the second shaft section 120. The baffle 112 can be used to cover the imprint mark 30 on the hose 10. In this way, when the protective cover 20 is moved, the outer surface of the hose 10 printed with the imprint mark 30 will not rub against the inner surface of the protective cover 20, thereby reducing the risk of adverse events.
