Wherein, Housing base piece 11a is equipped with as shown in figure 4, front is equipped with for the clamping groove 116 fixed with car body by clamping groove 116
The hook 117 of one；The front end of Housing base piece 11a is equipped with the protective pipe sleeve 118 of one, and to reduce number of parts, it is difficult to reduce assembly
Degree.In addition, the inner wall of 11 opening of shell is equipped with the installation preformed groove 115 for extending straight trough 113 in the axial direction, preformed groove is installed
115 depth at axial straight trough 113 gradually becomes smaller, and the depth that installation preformed groove 115 is most shallowly located is the 1/ of 11 wall thickness of shell
5, facilitate the installation of solution closing piece 12 and positioning component.
As an improvement, it is arcuate socket that lockhole 112 is conciliate in hole in rope 111,112 place plane of lockhole is conciliate in hole in rope 111
It is vertical with the solution axis direction of closing piece 12；The positioning end 131 of positioning pin 13 is that flat and its head is arc, flat fixed
Behind the hole in rope 111 or solution 112 grafting of lockhole of position pin 13 and arc, preferable axial limiting can be obtained.Position rear positioning pin
13 positioning end 131 and hole in rope 111 or the mating of solution lockhole 112 are cyclic annular face contact, and the circumferentia is perpendicular to the axis,
Therefore axial pull resistance is strong, and the positioning end of positioning pin 13 is not easy axially to deviate from from hole in rope 111 or solution lockhole 112.
As an improvement, the hole wall of radial pin hole 121, which is equipped with, prolongs two guide grooves 1211 that axially bored line direction extends, two
Guide groove 1211 is arranged with axial symmetry, and the plane that two guide grooves 1211 are constituted is vertical with the solution axis of closing piece 12；Positioning pin 13
Outer wall is equipped with two gib blocks 132 being axially arranged, and gib block 132 is slidably connected with corresponding guide groove 1211；For being oriented to
Positioning pin 13 it is flat it is mobile, matched with the arcuate socket of the reconciliation of hole in rope 111 lockhole 112, to obtain preferable axial limiting.
As an improvement, radial pin hole 121 is through-hole；There are two positioning pins 13, is separately mounted to the two of radial pin hole 121
End, adjustment spring 14 are squeezed between two positioning pins 13；There are two groups of holes in rope 111 and solution lockhole 112 on the shell wall of shell 11 simultaneously
It is arranged with axial symmetry.The stability in use of two sides stress balance, manipulatable end component is high.
Wherein, speed change end component 2 includes the active joint 21 connecting with speed changer, is connect with wirerope speed change end connector
The neck bush 27 of push rod 22, limited block 23, screw 24, Pipe protective joint component 25 and dirt-proof boot 26 and active joint 21.Push rod
22 head axially penetrates in the towing pad 211 of active joint tail portion 21, and the head of push rod 22 is equipped with groove or hole for installing
Radial limited block 23, limited block 23 are fixed by screw 24 and push rod 22.The middle part of active joint 21 is axially arranged with and draws
The pilot hole 212 for being oriented to limited block 23 that hole 211 is connected to；When positioning pin 13 falls into hole in rope 111, limited block 23 with
There are the default spacing d2 reversely pulled for anti-throw-out lever 22 by active joint 21, pilot holes between the rear wall of pilot hole 212
212 rear wall refers to the end hole wall far from speed changer；It is living as caused by speed changer under the shock effect of vehicle travel process
The shaking of dynamic connector 21 will not influence push rod 22, so that the wirerope connecting with push rod 22 be kept not to be subjected to displacement, avoid steel wire
The unconventional decrease of the tensile strength of rope, long service life.
In the present embodiment, presetting spacing d2 is preferably 3.5mm~4.5mm, and optimal is 4mm, presets the too long need of spacing d2
It increases hole in rope 111 and solves the pitch of holes d1 of lockhole 112, this will increase the difficulty of unlock operation；Hole in rope 111 and unlock
The pitch of holes d1 in hole 112 is 26~28mm；When the moving distance of active joint 21 is 23mm when the gap namely unlock of d1 and d2
Most preferably, P gear can be accurately unlocked, while the operation for solving closing piece 12 is again effortless.
