In this embodiment, in order to enable the first connecting piece and the second connecting piece to rotate downward relatively without interference of the locking block and the first locking piece and the second locking piece, the first matching portion and the second matching portion may be formed on the upper end surfaces of the first connecting piece and the second connecting piece, and have a longer groove for allowing the first locking piece and the second locking piece to be relatively far away, and a stopper capable of hooking the first locking piece and the second locking piece is formed on the groove to prevent the first locking piece and the second locking piece from being separated from each other when in a locked state.
When the elastic piece is a spring, two ends of the spring are respectively abutted to the first locking piece and the second locking piece, when the elastic piece is in a locking state, the first locking piece and the second locking piece are relatively far away from each other under the action of the elastic force of the spring and are matched and locked with the first matching portion and the second matching portion, and when the elastic piece is unlocked, the elastic force of the spring is overcome to enable the first locking piece and the second locking piece to be relatively close to each other so as to be separated from the first matching portion and the second matching portion to realize unlocking. In this embodiment, the first and second engaging portions may be grooves formed on the ends of the first and second connecting members. This embodiment is preferred because it is easier to arrange and has a relatively simple structure compared to the extension spring embodiment.
For the second embodiment, when the elastic member is one and is a tension spring, two end portions of the tension spring are respectively connected with the first portion and the second portion, at this time, in the locked state, the first locking member and the second locking member are relatively close to each other under the elastic force of the tension spring and are locked in cooperation with the first matching portion and the second matching portion, and in the unlocked state, the elastic force of the tension spring is overcome to relatively separate the first locking member and the second locking member from each other so that the first locking member and the second locking member are relatively separated from each other and are separated from the first matching portion and the second matching portion to achieve unlocking. In this embodiment, in order to enable the first connecting piece and the second connecting piece to rotate downward relatively without interference of the locking block and the first locking piece and the second locking piece, the first matching portion and the second matching portion may be formed on the upper end surfaces of the first connecting piece and the second connecting piece, and have a longer groove for allowing the first locking piece and the second locking piece to be relatively far away, and a stopper capable of hooking the first locking piece and the second locking piece is formed on the groove to prevent the first locking piece and the second locking piece from being separated from each other when in a locked state.
When the elastic piece is a spring, two ends of the spring are respectively abutted to the first portion and the second portion, when the elastic piece is in a locking state, the first portion and the second portion are relatively far away under the action of elastic force of the spring, and the first locking piece and the second locking piece are respectively matched and locked with the first matching portion and the second matching portion. In this embodiment, the first and second engaging portions may be grooves formed on the ends of the first and second connecting members. This embodiment is preferred because it is easier to arrange and has a relatively simple structure compared to the extension spring embodiment.
Specifically, locking mechanical system still including can drive the unlocking piece of locking mechanical system unblock, unlocking piece including slide the setting and be in the locking body on unblock body, set up and be in the unblock body on and can along with the unblock body slide and drive first locking piece with first cooperation portion first unblock portion that breaks away from, set up and be in the unblock body on and can along with the unblock body slide and drive second locking piece with second cooperation portion second unblock portion that breaks away from.
