In this embodiment, the second fastener is the same with the connected mode of second butt joint end, and the connected mode of first fastener and first butt joint end is different, and once the fastening can be through the tight fit of joint portion with the draw-in groove, carries out the chucking with first fastener and first butt joint end, can utilize the circumferential direction of draw-in groove restriction joint portion, can utilize the tight fit between the two again, restricts axial displacement between the two, prevents that the embroidery head from taking off from the operating handle pine during the use, improves stability and the security of using.
In this embodiment, if the screw locking direction is clockwise when the first fastening member is connected to the first butt end, the screw locking direction of the second fastening member to the second butt end is counterclockwise, that is, the locking directions of the first fastening member and the second fastening member are opposite, so that they are restricted with each other, and the locking effect is better.
Example three: referring to fig. 8 to 12, an embroidery machine with secondary fastening has a structure substantially similar to that of the first embodiment, and is different in that: the top of the first butt joint end is provided with a top thread 25, the bottom of the first fastener is provided with a bottom thread 26, and the first butt joint end and the first fastener are connected with the bottom thread through the top thread in a threaded manner.
In this embodiment, the first fastening is performed by a screw connection, and the screw connection is performed by a top screw and a bottom screw, which is different from the first and second embodiments in a first fastening manner.
Further, in this embodiment, the thread direction of the top thread and the bottom thread is opposite to the thread direction of the internal thread and the external thread. Assuming that the top and bottom threads are left-handed threads, the inner and outer threads are right-handed threads, and vice versa.
The top thread and the bottom thread are coarse threads, and the internal thread and the external thread are fine threads. Thus, the pitch of the top and bottom threads is greater than the pitch of the inner and outer threads.
The lead angle of the coarse thread is large, and the lead angle and the thread pitch of the coarse thread are large, so that the number of threads in the same lead distance is smaller, the requirement on the accuracy of installation for the coarse thread is lower, and the installation and the disassembly are convenient. But the anti-vibration performance is relatively weak, the self-locking performance and the sealing performance are relatively poor, and the looseness is easy to occur. The fine thread has a small lead angle and a small thread pitch, and the number of the same lead distance threads is large, so that the sealing performance is good, the vibration resistance is weak, the self-locking performance is good, the loosening is not easy to occur, and the requirement on the mounting accuracy is high.
Therefore, in the present embodiment, in order to improve the convenience of the first connection and installation of the operating handle and the tattooing head and improve the installation efficiency, the first fastening member and the first abutting end use the coarse thread.
When operating handle and embroidery head are connected, first fastener inserts in the first butt joint end, carry out quick counterpoint through thick tooth screw thread, then carry out quick locking location, realize once fastening, so not only realized once fastening, moreover, what second fastener and second butt joint end adopted is thin tooth screw thread, once fastening has given direction and counterpoint of secondary thin tooth screw thread, when making second fastener and second butt joint end carry out the spiro union, can be direct quick connect (in the conventional thin tooth threaded connection mode, probably many times spiro union all is difficult to aim at, lead to the emergence of screw thread smooth silk phenomenon even). Therefore, the first fastening piece and the first butt joint end adopt the coarse thread, and the second fastening piece and the second butt joint end adopt the fine thread, so that the connection strength and the stability can be ensured, and meanwhile, the smoothness and the convenience of installation can be improved.
Referring to fig. 12, in this embodiment, after a long time and a high frequency vibration, the coarse thread may loosen first, that is, the tattooing head moves downward relative to the operating handle, that is, the top thread moves downward relative to the bottom thread, and a loosening movement occurs, however, because the thread lead angle of the coarse thread is larger than that of the fine thread, under the interference of the same external force, the loosening range of the coarse thread is larger than that of the fine thread, under the pushing of the loosening movement, the distance between the external thread and the internal thread gradually disappears along with the loosening direction, and is squeezed, the generated pressure is gradually increased, and further the contact area and the frictional resistance between the external thread and the internal thread are increased, so that the fastening strength between the second fastening member and the second butt joint end is increased, that is, the fastening performance between the operating handle and the tattooing head is improved. Therefore, in this embodiment, not only the spiral opposite direction of top screw thread, bottom screw thread and internal thread, external screw thread can give reverse effort, increases a fastening effect, simultaneously because the use of coarse thread and fine thread, further increases fastening effect, and both restrict each other, effectively prevent that the emergence of the pine phenomenon from appearing in the embroidery head, improve stability, fastness and the security of the embroidery in-process, prevent that the embroidery head from droing and taking place the potential safety hazard.
In this embodiment, the top thread is a top internal thread and the bottom thread is a top external thread. The top internal threads will be provided on the inner wall of the through hole.
Example four: referring to fig. 13 and 14, an embroidery machine with secondary fastening has a structure basically similar to that of the third embodiment, and is different from the third embodiment in that: the top thread is a top external thread, and the bottom thread is a top internal thread.
