Meanwhile, the force storage slide seat 2 pushes the hanging needle 22 to slide along the force storage section 111 through the swing rod 21, when the poking needle 103 passes through the first locking point 16, the hanging needle 22 pushes the first locking piece 4, under the action of the second reset spring 19, the self-locking square rod 51 slides and falls into the interlocking step opening 43, at the moment, the second locking piece 5 closes the second locking point 17, and the first locking piece 4 is locked into an open state, so that the hanging needle 22 slides to the second locking point 17 along the force storage section 111 to be locked.
At the same time, during this process, the setting needle 103 enters into the pulling hook opening in the pulling slide 23 in order to push the pulling slide 23 inwards. When the traction sliding seat 23 slides and transfers from the circular arc section 131 to the straight line section 132, the traction sliding seat 23 deflects relative to the power storage sliding seat 2, so that the traction hook opening 24 and the poking needle 103 can be hooked and twisted.
Pop-up opening drawer 101 process:
the user presses the drawer 101 again, and at this time, the hanging needle 22 pushes the second locking member 5 open, and the power storage slide 2 is pulled outwards under the action of the power storage tension spring 3, so that the drawer 101 is pushed out by pushing the pushing needle 103.
Meanwhile, after the hanging needle 22 pushes away the second locking member 5, the self-locking square rod 51 is pulled out of the interlocking step opening 43, under the action of the first reset spring 18, the first locking member 4 resets to close the first locking point 16, and the second locking member 5 is locked in an open state, so that the hanging needle 22 can slide to an initial position along the reset section 112 for resetting.
Simultaneously, in the process, the pulling slide seat 23 is pulled outwards by the pulling needle 103, and in the process of sliding and resetting the pulling slide seat 23 from the straight line section 132 to the circular arc section 131, the pulling slide seat 23 is reset and deflected relative to the power storage slide seat 2 so as to release the hook buckle twisting between the pulling hook opening 24 and the pulling needle 103, so that a user can pull the drawer for the second time.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
