The release mechanism has a release rod body. The telescopic control mechanism recorded in this patent document is basically the same as the telescopic baton with the Chinese patent application number 201710269991.7. The same problem is: to complete braking and release, the length of the release rod body must be Occupies most of the axial space of the outer tube, and the free end of the release rod needs to face backward. When the inner tube is retracted, there is no more space in the outer tube because it is occupied by the release rod.
The connecting part is a drawstring, but in the actual experiment process, the drawstring is easily broken during the repeated sticking and closing process, which makes the life of the baton short, the structure is unreliable, the maintenance is frequent, and the cost is high

Abstract
The invention discloses an extending-and-contracting reverse pull concealed type unlocking mechanism and an unlocking method. The extending-and-contracting reverse pull concealed type unlocking mechanism comprises an unlocking driving mechanism, a buckling mechanism and an extending-and-contracting type unlocking reverse pull rod. The extending-and-contracting type unlocking reverse pull rod is arranged between the unlocking driving mechanism and the buckling mechanism. According to the unlocking method, the unlocking driving mechanism applies a reverse pull force to the extending-and-contracting type unlocking reverse pull rod, and the buckling mechanism is unlocked through the reverse pull force. According to the extending-and-contracting reverse pull concealed type unlocking mechanism and the unlocking method, an unlocking end of an unlocking rod is arranged toward the backside, and the space occupied by the unlocking rod is small; after a night stick contracts, the extending-and-contracting type unlocking reverse pull rod can be withdrawn, an inner chamber of a holding rod can achieve the sufficient application space, and the space can be fully utilized; and in addition, the extending-and-contracting type unlocking reverse pull rod is used, and therefore, the extending-and-contracting reverse pull concealed type unlocking mechanism is stable in structure and low in maintenance cost.
Description
technical field [0001] The present invention relates to batons, especially batons that are unlocked by pulling back. Background technique [0002] The telescopic baton is a kind of police equipment. The telescopic baton is in a telescopic state when it is not in use, and it is used by throwing it out when it is used. [0003] Present retractable baton mainly has two kinds of structures, and a kind of is resistance structure, and another kind is to realize locking and unlocking by mechanical structure. [0004] A telescopic baton is disclosed in the patent document whose Chinese patent application number is 201710269991.7 and the filing date is 2017.4.24. Including outer tube; middle tube; rear tube; middle tube locking mechanism; rear tube locking mechanism; unlocking mechanism; , the first butterfly is slidably matched with the sliding groove of the first butterfly, the side of the first butterfly facing the middle tube cavity has a first butterfly ear, and the center of ...
