Further, the connecting device of the present embodiment 1 further includes a reset prevention component 4. When retaining member 3 receives external drive to unclamping the position, retaining member 3 is located first slotted hole 11 or second slotted hole 21, should prevent reset assembly 4 simultaneously and be used for restricting retaining member 3 and slide back to the locking position, when the stealthy connecting piece of needs two above installation opposite directions of split, because of the unable installation state who judges the stealthy connecting piece and have the problem of split difficulty.
Referring to fig. 1-4 and 11, as a first specific structure of the anti-resetting assembly 4 in this embodiment 1, the anti-resetting assembly 4 includes a first stopper 41, a first elastic member 42 and a first base 43; one end of the first elastic member 42 is connected to the first stopper 41, and the other end of the first elastic member 42 is connected to the first base 43; the first connecting piece 1 is provided with a third slot 12, and the third slot 12 is communicated with the first slot 11 through a connecting port 13; the first stopper 41, the first elastic element 42 and the first base 43 are sequentially disposed in the third slot 12, and the first base 43 is fixedly disposed in the third slot 12 or at an opening of the third slot 12. Wherein, the connection port 13 may be located at the bottom of the third slot 12, that is, the bottom of the third slot 12 communicates with one side of the first slot 11, so that the first stopper 41 passes through the connection port 13 and abuts to the circumferential outer surface of the locking member 3. In addition, the third slot 12 may be formed to penetrate both sides of the first slot 11 to form an attachment opening 13, and the first stopper 41 may be abutted to the circumferential outer surface of the locker 3 after penetrating the attachment opening 13. When the locking member 3 is located at the locking position, the locking member 3 is pressed against the first stop block 41 through the connecting port 13 and enables the first elastic member 42 to be in a compressed state; when the retaining member 3 is in the release position, the retaining member 3 is positioned in the first slot 11, and the first elastic element 42 releases its deformation energy and drives the first stop 41 to move, so that the first stop 41 partially passes through the connection port 13 and restricts the sliding of the retaining member 3 back to the locking position.
The first elastic member 42 of this embodiment 1 may be made of a polymer material such as rubber or silica gel with elasticity, or may be a compression spring, which can deform and form deformation energy under external pressure, and the first elastic member 42 can recover its original shape after the pressure is removed. The first elastic member 42 of embodiment 1 is preferably a compression spring.
Therefore, when the hidden connecting member with unknown mounting direction is disassembled, the locking member 3 is moved by external force, and the following two situations are included: (1) the locking piece 3 positioned at the locking position is continuously moved towards the locking direction under the action of external force, at the moment, one end of the locking piece 3 is positioned in the first slotted hole 11, the other end of the locking piece 3 is positioned in the second slotted hole 21, and the first connecting piece 1 and the second connecting piece 2 are still in a connecting state; (2) retaining member 3 that is located locking position receives exogenic action to remove toward the loosening direction, makes retaining member 3 remove to the loosening position from locking position, when retaining member 3 is located the loosening position, inside all of retaining member 3 were located first slotted hole 11 promptly, first elastic component 42 released its self degeneration ability and the reconversion this moment, drives first dog 41 and supports and keep off or chucking retaining member 3, makes first dog 41 can restrict retaining member 3 and remove toward the locking direction once more. Limiting the locking piece 3 to slide back to the locking position through the stop block, the connecting device in the separated state can be prevented from being locked again, the locking effect of the locking piece 3 on the first connecting piece 1 and the second connecting piece 2 can be smoothly relieved by adopting two opposite external forces one by one to the plurality of connecting devices, the purpose of splitting the connecting device in an unknown installation state is achieved, the efficiency is high, and the first component 10 or the second component 20 is prevented from being damaged.
In the same principle, the first anti-reset assembly 4 structure of this embodiment 1 can be disposed on the second connecting member 2, that is, the second connecting member 2 is provided with a fourth slot (not shown) communicated with the second slot 21, the anti-reset assembly 4 is located in the fourth slot, when the locking member 3 is located at the releasing position, that is, the whole locking member 3 is located inside the second slot 21, at this time, the first elastic member 42 releases its own transformation energy to restore the original state, and drives the first stopper 41 to block or clamp the locking member 3, so that the locking member 3 located in the second slot 21 cannot enter the first slot 11, thereby realizing the relative detachment between the first connecting member 1 and the second connecting member 2.
The first base 43 can be detachably disposed in the third slot 12, referring to fig. 1-4, for example, an external thread structure is disposed on an outer surface of the first base 43, an internal thread structure is disposed in the third slot 12 and is connected to the first base 43 in a matching manner, and the first base 43 is fixedly disposed in the third slot 12 in a screw-fit manner. In addition, the first base 43 may be non-detachably disposed at the opening of the third slot 12, for example, by being fixed in the third slot 12 by gluing or other means.

Meanwhile, in order to ensure that the locker 3 is not interfered by the stopping portion 412 during the rotation, the stopping portion 412 may be provided with a tooth portion that is engaged with the external thread structure of the locker 3.
Further, when the locking member 3 is located at the releasing position, in order to enable the first connecting member 1 and the second connecting member 2 to be relatively connected again, the locking member 3 needs to be able to slide to the locking position, at this time, the first elastic member 42 needs to be reset to the compressed state, and the locking member 3 abuts against the abutting portion 412 of the first stopper 41 so as to enable the first elastic member 42 to maintain the compressed state. Therefore, the locking member 3 can be installed again after being placed in the locking position after the first base 43, the first elastic member 42 and the first stopper 41 are removed one by one, but this method is very complicated and inefficient. Therefore, referring to fig. 1, a first reset groove 14 communicating with the third groove 12 is formed on the surface of the first connecting member 1, an external tool (such as a rod) passes through the first reset groove 14 and abuts against the surface of the first stopper 41, the first stopper 41 is driven to move so as to reset the first elastic member 42 to a compressed state, at this time, the retaining member 3 and the abutting portion 412 of the first stopper 41 are separated from each other, and the locking member 3 is driven to smoothly slide from the release position to the locking position by an external force, so that the first connecting member 1 and the second connecting member 2 are reconnected.
In order to facilitate the external tool to drive the first elastic element 42 to return to the compressed state, please refer to fig. 13, a circular hole 411a may be formed on the block body 411 of the first block 41, and the external tool (such as a rod or the like) passes through the first return slot 14 and then is inserted into the circular hole 411a to drag the first block 41 to move, so as to achieve the purpose of compressing the first elastic element 42.
