Drawbacks described above.
What the purpose of this utility model was realized in：A kind of lock device, including lock tongue, Tiebar structure and plectrum knot
Structure；The lock tongue is fixed on Tiebar structure, and the Tiebar structure is fixed in plectrum structure；It is characterized in that：It is described
Plectrum structure include spanner column, spanner plectrum and spanner, the spanner is coaxially fixed with spanner column, the spanner
Column coordinates with spanner plectrum；The Tiebar structure includes that lock tongue pull rod, the vertical piece of pull rod and resetting spring, the lock tongue are drawn
Bar passes through the vertical piece of pull rod and spanner plectrum to be connect with lock tongue, and the pull rod is vertical to be provided with reset bullet between piece and lock tongue plectrum
Spring.
As preferred technical solution：The spanner plectrum is L-type structure, the spanner plectrum include long end with it is short
End, the short end are provided with the upper hole of guiding, waist-shaped hole are provided on the long end.
As preferred technical solution：The spanner column includes cylinder-shaped body and taper pin, taper pin setting
In the side of cylinder-shaped body, the taper pin coordinates with waist-shaped hole.
As preferred technical solution：The pull rod founds on piece and is provided with guiding lower opening, the guiding lower opening with lead
The upward fixed lock tongue pull rod of hole cooperation.
The utility model dismounting simple in structure is extremely convenient, and the succinct cooperation of plectrum device and drag link mechanism makes structure more
Add firm, easy manipulation, service life has obtained effective extension while having saved production cost, larger using having with popularization
Social benefit.

Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings, but not as limitations of the present invention：It is a kind of
Lock device, including lock tongue 1, Tiebar structure 2 and plectrum structure 3；The lock tongue 1 is fixed on Tiebar structure 2, the drawing
Rod structure 2 is fixed in plectrum structure 3；It is characterized in that：The plectrum structure 3 include spanner column 4, spanner plectrum 5 with
Spanner 6, the spanner 6 is coaxial fixed with spanner column 4, and the spanner column 4 coordinates with spanner plectrum 5；The drawing
Rod structure 2 includes that lock tongue pull rod 7, the vertical piece 8 of pull rod and resetting spring 9, the lock tongue pull rod 7 pass through pull rod to found piece 8 and spanner
Plectrum 5 is connect with lock tongue 1, and the pull rod is vertical to be provided with resetting spring 9 between piece 8 and lock tongue pull rod 7.The spanner plectrum
5 be L-type structure, and the spanner plectrum 5 includes long end 5-1 and short end 5-2, and the short end 5-2 is provided with the upper hole 5- of guiding
It is provided with waist-shaped hole 5-4 on 3, the long end 5-1.The spanner column 4 includes cylinder-shaped body 4-1 and taper pin 4-2, institute
The taper pin 4-2 stated is arranged in the side of cylinder-shaped body 4-1, and the taper pin 4-2 coordinates with waist-shaped hole 5-4.The pull rod
It is provided with guiding lower opening 8-1, the guiding lower opening 8-1 on vertical piece 8 and fixes lock tongue pull rod 7 with upper hole 5-3 cooperations are oriented to.
When specific implementation：
