Referring to fig. 1-3, the outer diameter of the round rod 3 is smaller than the inner diameter of the ring 5, and the outer diameter of the sleeve 4 is smaller than the outer diameter of the cavity 11, so that friction between the inner wall of the ring 5 and the threaded portion 31 is avoided, and abrasion is avoided.
Working principle: when the invention is used in daily life, if the chip 33 in the placing cavity 32 is damaged, when the chip is needed to be replaced, a worker specially keeping the seal disassembles the side cover 12 from the seal handle 1, presses down the ring 5 by a tool, compresses the elastic piece 51 to enable the ring 5 to be far away from the spike 42 at the bottom of the sleeve 4, then rotates the sleeve 4 to enable the sleeve 4 to move downwards until the placing cavity 32 is completely exposed, takes out the chip 33 to replace, and records that the spike 42 cannot contact with the top surface of the ring 5 when the sleeve 4 moves downwards, so that the top surface of the ring 5 forms a circular scratch, if someone happens, the chip 33 is unexpectedly replaced, the seal becomes an illegal tool for someone, and because the worker not specially keeping the seal does not know that the top surface of the ring 5 cannot cause the circular scratch, the ring 5 is not deliberately pressed down, and whether the seal is maliciously moved by someone is judged by judging whether the top surface of the ring 5 has the circular scratch or not, so that the seal is prevented in advance, and loss is avoided.
Referring to fig. 4-5, to increase the safety of the present case, the applicant also makes the following improvements:
a notch 34 is arranged on the round rod 3 below the round ring 5, a limit piece 7 is arranged in the notch 34, one end of the limit piece 7 is provided with a hinge part 71, the other end of the limit piece 7 is fixedly provided with a pressure spring 8, and the pressure spring 8 is contacted with the side wall of the notch 34, so that the limit piece 7 at the end rotates out of the notch 34, and the movement of the round ring 5 in the axial direction of the round rod 3 can be limited;
the two ends of the pin shaft 6 after passing through the hinge part 71 are respectively hinged with two ends of the inner wall of the notch 34, so that the limiting piece 7 is hinged with the round rod 3, the limiting piece 7 is made of a material which can be adsorbed by a magnet, such as an iron material, a magnet and the like, and the round rod 3, the circular ring 5, the pressure spring 8, the seal handle 1 and the elastic piece 51 are made of a material which can not be adsorbed by the magnet.
When the chip 33 needs to be disassembled, a rotating magnetic field is firstly applied to the limiting piece 7, so that the limiting piece 7 rotates around the pin shaft 6 into the notch 34 and does not exceed the outer wall of the round rod 3, at the moment, the round ring 5 can be pressed down, the sleeve 4 can move along the axial direction of the round rod 3 to open the 32 placement cavity, and then the chip 33 is taken out.
The design increases the disassembly difficulty, the rotating magnetic field needs to be increased, the equipment is less at present, lawless persons do not need to know the disassembly and assembly mode, and the direction of the rotating magnetic field can be used as an encryption item, so that the safety is very high. The rotating magnetic field of the present embodiment may refer to the rotating magnetic field technology of the current magnetic invisible screw.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
