After can directly fastener upwards being pushed away to the base plate rear end face that makes fastener exceed sliding shoe chute hole during dismounting, can extract switch block from lock housing front end.
As preferably, described switch sliding shoe upper rear end is provided with positive stop strip, the squab panel top of described sliding shoe chute hole is provided with for passing the spacing guide through hole of positive stop strip, and in lock housing, be positioned at spacing guide through hole rear and be arranged at the postive stop baffle coordinating with positive stop strip, the lowermost end of described postive stop baffle exceeds the top of described fastener.
This height design of postive stop baffle makes space fastener in lock housing leave enough spaces to the region going out, and is beneficial to when dismounting fastener, stretches in lock housing and will on fastener, advance row dismounting.
When button moves to the back-end, thereby positive stop strip is finally against and on postive stop baffle, limits each slidably stroke of parts.
As preferably, on the squab panel of described pin body chute hole and sliding shoe chute hole, be provided with for being socketed the spacing block set of back-moving spring.
Spacing block set can position back-moving spring, prevents its sideslip in telescopic process.
As preferably, described sliding shoe chute hole base wall panel front end is provided with the transmission gathering sill that is communicated with pin body chute hole and moves around for linkage part.
As preferably, described lock housing rear end is provided with lock housing installation cavity, in described lock housing installation cavity, is provided with some reinforcing ribs.
Adopt lock housing installation cavity can directly be buckled on the hurdle frame on a hurdle, easy for installation.
In sum, the present invention has following beneficial effect:
The present invention inserts simply by latch components and switch block that lock housing is assembled, snapping is fixed, by the band pendulum lock pin that slidably reciprocates of switch block, unblanked again, simple in structure, assembling, convenient disassembly, be difficult for stuckly, each parts can arbitrarily be changed, and are convenient to maintenance, and each parts are not fragile, long service life.
