The specific embodiment

Referring to accompanying drawing, the utility model comprises handle support 1, goes up handle sheath body 6, lower handle sheath body 5, be installed with the steel wire that is used to drive slide key in the handle support 1, slide key is used for the vehicle frame locking mechanism is locked or release the lock, and steel wire 13 is connected slide key with the other end after steel wire 14 is drawn from last handle sheath body 6, lower handle sheath body 5.

Be provided with end socket 10 and end socket 9 at last handle sheath body 6 and lower handle sheath body 5 axial both sides, handle support 1 passes end socket, handle support 1 is captiveed joint by latch structure with end socket, be respectively equipped with

end socket hole

24 and 25 on

end socket

10 and 9 circle wall, on handle support 1 and end socket pin-and-hole 24 and the 25 cooresponding positions hole 19 and hole 20 are set, by pin 21 and pin 22 each end socket of locking and handle supports 1, end socket 10 can not be rotated relative to handle support 1 with end socket 9.

Last handle sheath body 6 and lower handle sheath body 5 and end socket 10 and end socket 9 sockets can rotate with respect to end socket.

Lower handle sheath body 5 inwalls are provided with safety pin chute 8, be provided with safety pin 11 in the safety pin chute 8, safety pin 11 can slide along safety pin chute 8, is provided with the bar shaped perforate above the safety pin chute 8, safety pin 11 is provided with toggle 15, and toggle 15 can slide along the bar shaped perforate of safety pin chute 8.

Be provided with strip groove 30 in the middle of the safety pin 11, be used to place spring 12, spring 12 holds out against safety pin chute 8 inwalls, and safety pin 11 1 ends are provided with a bar shaped raised line 31, and raised line 31 stretches into the cotter way 16 that is provided with on end socket 10 outer walls.Safety pin 11 is under the promotion of spring 12 under the normal condition, and raised line 31 is inserted in the cotter way 16, and handle sheath body 6 and lower handle sheath body 5 can not be relatively rotated with end socket.

Be installed with in the handle support 1 for the steel wire that drives slide key; Upper handle sheath body 6 is interlocked with lower handle sheath body 5 handle support 1 is surrounded; Handle support 1 is provided with radial direction through hole 23 by upper handle sheath body 6 and the part that lower handle sheath body 5 surrounds; Be installed with rotating shaft 7 in the through hole 23; One end of rotating shaft 7 is provided with gear; Handle support 1 overcoat has gear ring 2; Gear engagement in gear on the gear ring 2 and the rotating shaft 7; Steel wire is connected with rotating shaft 7; Two screws are arranged on the gear ring 2; Available screw is fixing with upper handle sheath body 6 or lower handle sheath body 5 with gear ring 2

Rotating shaft 7 is the tubular, hollow structure, there is strip gab both sides, one end of steel wire 13 and steel wire 14 has cylinder head 17 and cylinder head 18 respectively, cylinder head 17 and cylinder head 18 are placed hollow part 29, steel wire 13 and steel wire 14 go out to pass by the strip gab of hollow rotating shaft both sides, thereby steel wire is around in the rotating shaft 7 when hollow rotating shaft 7 rotates.

Last handle sheath body 6 is cylindric after fastening with lower handle sheath body 5, and lower handle sheath body 5 is provided with screw with last handle sheath body 6 cooresponding positions, can will go up handle sheath body 5 and 6 lockings of lower handle sheath body by screw.

The utility model device at first will be pulled toggle 15 and safety pin 11 be dragged in the safety pin chute 8 fully the cylinder of handle sheath body 6 and lower handle sheath body 5 fastenings rotations in when using.

Steel wire 13 is free exceptionally straight state with steel wire 14 at first, along with the turning gear torus 2 of last handle sheath body 6 with lower handle sheath body 5 also rotates, gear ring 2 drives rotating shaft 7 by engaging gear and rotates, steel wire 13, steel wire 14 can be around in the rotating shaft 7, the change of steel wire 13, steel wire 14 states and cause that contraction also drives and steel wire other end bonded assembly slide key reaches the purpose of the vehicle frame locking mechanism that gets loose.

Same reason, under the described in front situation, when last handle sheath body 6 and lower handle sheath body 5 backward rotation, the steel wire that steel wire 13, steel wire 14 are around in rotating shaft top restores.This moment, cotter way 16 can be aimed at and stretch into to safety pin 11 also, and handle sheath body 6 and lower handle sheath body 5 locking positions can not rotated because of accidentalia.
