The circular hole of plate left end, at this point, hand control valve handle can be moved forward freely, hand control valve handle base as fulcrum, position by A to B,
B location is reached, spool pull-out is reached into braking action under the drive of connection sheet, at this point, handle valve slider is put down, spring is stretched
Exhibition resets, and the boss of handle valve slider lower part enters among hand control valve limiting plate in the circular hole of empty slot right end, and circular hole gives handle
Valve slider position-limiting action, hand control valve handle at this time just cannot shift position again, play position-limiting action.
When driving, it is equally lifted up handle valve slider, the boss of spring-compressed, handle valve slider lower part leaves hand control valve
The circular hole of limiting plate right end, at this point, hand control valve handle can be moved backward freely, position is being connected by B to A after reaching location A
Spool is pushed back under the drive of piece, has the function that release braking, handle valve slider is put down, spring release, handle valve slider
The boss of lower part enters in the circular hole of hand control valve limiting plate left end, and circular hole gives handle valve slider position-limiting action, hand control valve handle
At this time just cannot shift position further along, play position-limiting action.
Further preferably, boss is arranged in the lower end of handle valve slider, and boss is used cooperatively with circular hole, and boss can be installed on
In circular hole, play the role of limit.
Further preferably, draw ring is arranged in the upper end of handle valve slider, lifts handle valve slider convenient for driver.
Further preferably, hand control valve limiting plate is fixed by bolts on manual valve body.
Further preferably, handle valve sleeve is screwed on the screw thread of hand control valve handle upper portion, and handball is screwed into hand control valve hand
The upper end of handle.
Compared with prior art, the utility model has the advantages that:
The utility model structure novel can play the role of limit, even if encountering hand control valve handle to hand control valve handle
It will not be moved, safety is preferable, can prevent the generation of contingency, and the safety for being conducive to production carries out.

Specific implementation mode
The utility model embodiment is described further below in conjunction with the accompanying drawings:
Embodiment 1
As shown in Figs. 1-2, hand control valve limiting device described in the utility model, including manual valve body 1, manual valve body 1
Right side setting support handle seat 10 and spool 9,9 one end of spool be mounted on inside manual valve body 1, the other end is exposed at hand control valve
Outside valve body 1, hand control valve handle 7 is housed on support handle seat 10, handball 4, the spool 9 is arranged in the upper end of hand control valve handle 7
It is connected by connection sheet 8 with hand control valve handle 7, the upper end setting hand control valve limiting plate 2 of manual valve body 1, hand control valve limit
The middle part of plate 2 is provided with slideway 12, and circular hole 11 is arranged in the both sides of slideway 12, and hand control valve handle 7 is mounted on the inside of slideway 12, manual
