[0020] In the description of the present disclosure, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0021] Example

[0022] like Figure 1 As shown, this embodiment provides a precision watch cover opening device, including a base 1, a support 2 is welded or integrally formed on the surface of the base 1, the cross-section of the support 2 is a "7"-shaped structure, the top of the support 2 is movably connected to a lifting column 3, the lifting column 3 is movably connected to a cover screwing rod 4, the bottom end of the cover screwing rod 4 passes through the lifting column 3 and is detachably connected to a bottom cover opening cup mouth 5.

[0023] Specifically, a threaded hole is provided at the top of the pillar 2, a first internal thread is provided in the threaded hole, a first external thread is provided on the outer side of the lifting column 3, and the lifting column 3 can be movably connected to the threaded hole through the cooperation of the first external thread and the first internal thread. By rotating the lifting column 3, the first external thread and the first internal thread cooperate, so that the lifting column 3 can move up and down in the threaded hole, thereby driving the bottom cover cup mouth 5 to move up and down.

[0024] Specifically, the top of the lifting column 3 is integrally formed with a threaded sleeve 31, the inside of the threaded sleeve 31 is provided with a second internal thread, the outer side of the upper part of the cover screwing rod 4 is provided with a second external thread, and the second internal thread is matched and connected with the second external thread. By rotating the threaded sleeve 31, the lifting column 3 is driven to rotate synchronously, so that the lifting column 3 moves up and down to a suitable position, so that the bottom cover cup opening 5 and the cover are combined, and the cover screwing rod 4 is rotated at this time, and the cover screwing rod 4 rotates to drive the bottom cover cup opening 5 to rotate synchronously, and moves in the vertical direction during the rotation process, and the bottom cover cup opening 5 drives the cover to rotate, so as to disassemble or tighten the cover.

[0025] Furthermore, a mounting hole is provided at the bottom end of the cover screwing rod 4, a fixing hole is provided on the side of the cover screwing rod 4 and is connected to the mounting hole, one end of the bottom cover cup 5 is embedded in the mounting hole, and a fixing screw 51 is threadedly connected in the fixing hole. Different models of watches have different shapes of watch covers and need different bottom cover cups 5. When a different bottom cover cup 5 needs to be replaced, the fixing screw 51 is unscrewed, the bottom cover cup 5 is removed and replaced, and then the fixing screw 51 is tightened to fix it.

[0026] Furthermore, the lifting column 3 is threadedly connected with a fixing nut 6 at a position above the column. The outer side of the lifting column 3 is threadedly connected with a fixing nut 6. After the lifting column 3 is moved to a suitable position, the lifting column 3 is locked by tightening the fixing nut 6 to prevent the lifting column 3 from moving when the cover is opened or installed.

[0027] Furthermore, the top end of the cap screwing rod 4 is fixedly connected with a turning handle 41. The cap screwing rod 4 is driven to rotate by turning the turning handle 41, which is convenient for operation.

[0028] Furthermore, the pitch of the first external thread is greater than the pitch of the second external thread. The pitch of the first external thread is greater than the pitch of the second external thread, which facilitates and quickly positions the bottom cover cup opening 5, and the pitch of the second external thread is equal to the pitch of the thread of the watch cover, so that the watch cover can be disassembled, so the pitch of the second external thread is very small. If the bottom cover cup opening 5 is moved only by the second external thread, the number of turns required will be very large, and the operation will be very difficult, so the pitch of the first external thread needs to be much greater than the pitch of the second external thread.

[0029] In one embodiment, a guide groove 11 is provided on the surface of the base 1 below the bottom cover cup opening 5, and a positioning jig 7 is movably connected in the guide groove 11. The positioning jig 7 is used to place and fix the watch, and the positions of the watch cover and the bottom cover cup opening 5 are made to correspond by moving the positioning jig 7 left and right in the direction of the guide groove 11. At this time, the staff only needs to adjust the left and right directions, and the other directions are fixed, which is convenient for positioning.

[0030] The working principle of the utility model is as follows: according to the watch cover model that needs to be disassembled and assembled, a suitable bottom cover cup mouth 5 is selected, the bottom cover cup mouth 5 is installed to the bottom end of the cover screwing rod 4 and then fixed by the fixing screw 51, the fixing nut 6 is rotated to loosen the restriction on the lifting column 3, and then the threaded sleeve 31 is rotated to drive the lifting column 3 to move upward, so that the bottom cover cup mouth 5 is away from the positioning jig 7, which is convenient for installing the watch, and the watch is installed on the positioning jig 7, and the threaded sleeve 31 is reversed to move the lifting column 3 downward. After the bottom cover cup mouth 5 and the watch cover are matched, the fixing nut 6 is rotated to lock the lifting column 3, and then the turning handle 41 is rotated to drive the cover screwing rod 4 to rotate, and the watch cover cup mouth is driven to rotate to disassemble or install the watch cover.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present disclosure.
