Chassis 1 and rotation seat 2 are rotation connection, and specially 1 two sidewalls of chassis are penetrated with 2 two sidewalls of rotation seat by pin shaft
To realize rotation connection.
Lock tongue 6 and return spring 7 are equipped in rotation seat 2.Lock tongue 6 and rotation seat 2 are sliding setting, and specific structure is rotation
U-bracket 8 is equipped in seat 2, the hollow space of u-bracket 8 is slideway, and u-bracket 8 and rotation seat 2 are fixed, and lock tongue 6, which is in, to be slided
In road, 6 part of lock tongue can be extend out to outside rotation seat 2 from slideway after 6 stress of lock tongue, can also be retracted to inside slideway.Herein
Fixed plate is equipped in rotation seat 2, u-bracket 8 is fixed with fixed plate, therefore the hollow space of u-bracket 8 is equivalent to be sliding
Road, lock tongue 6 can be slided on slideway.
Positioning bolt 9 and rotation seat 2 are fixed, and fixing bolt 10 and lock tongue 6 are fixed, and installation bolt 11 and rotation seat 2 are fixed.
Positioning bolt 9 is located at the left of fixing bolt 10 herein, and installation bolt 11 is located at the lower right of fixing bolt 10.In u-bracket 8
Kidney slot 12 is offered, fixing bolt 10 is pierced by by kidney slot 12, the length direction of kidney slot 12 and the direction of motion one of lock tongue 6
It causes.
Driving torsional spring 13 be sheathed on positioning bolt 9, driving torsional spring 13 one end be connected with fixing bolt 10, the other end and
Driving wire 4 is connected.
One end of return spring 7 is connected with installation bolt 11, and the other end is connected with fixing bolt 10.
Fastener 5 is located at the one side of rotation seat 2, is specifically just proximate to the position where lock tongue 6, and 5 face of fastener
Card slot 14 is offered on towards the face of lock tongue 6,14 quantity of card slot herein is two.Fastener 5 is by the identical card of at least two shapes
Piece is bolted or is welded and fixed to be formed.Fastener 5 and chassis 1 are fixed herein, can be fixed by bolt
Or by being welded and fixed.
Driving handle 3 includes handle portion and handle casing 15, and handle portion includes operation portion 16 and rotation section 17.Herein
Rotation section 17 is the cylindrical body that a periphery offers at least two locating slots 18, and the cylindrical body and handle casing 15 are that rotation connects
It connects.The fixing groove 19 fixed with driving wire 4 is offered on rotation section 17, driving wire 4 in incoming fixing groove 19 by being consolidated
It is fixed, driving wire 4 can be pulled mobile when rotation section 17 rotates.
It is additionally provided with elastic slice in handle casing 15, elastic slice includes main part 20, lug boss 21 and is located at 20 both ends of main part
End head 22, lug boss 21 is located on main part 20.Limiting slot 23 there are two being opened up on handle casing 15, two end heads 22
It is respectively protruding into corresponding limiting slot 23, so that there are gaps between 15 inner wall of main part 20 and handle casing.Main part 20 with
The periphery of cylindrical body offsets, and can squeeze main part 20 when cylindrical body rotation and make elastic slice deformation occurs, and 21 meeting of lug boss
It is removed from current locating slot 18, when lug boss 21 moves to the position of remaining locating slot 18, elastic slice reset can drive convex
It plays portion 21 and protrudes into locating slot 18 and realize and mutually block.The corresponding lock tongue 6 of one of locating slot 18 is in and 14 engaging position of card slot herein
