Handle includes the Handheld Division and insertion section being sequentially connected, and insertion section side wall is provided with annular slot, and insertion section is remote
Handheld Division one end to the distance of annular slot is L2, L2 ＜ L1；
Alignment pin includes the pull head and pin rod being sequentially connected, and pull head is positioned at hand body exterior is pressed, and pin rod is away from pull head one end
Through in through hole insertion slot, one end that pin rod is located in slot has the slide guide face being obliquely installed, and is provided with outside pin rod
Bearing and elastic component, bearing is set in outside pin rod and its inner ring is fixedly connected with pin rod, and elastic component is located at bearing away from pull head
Side, and elastic component both ends are respectively with bearing outer ring and pressing hand body and fixing.
Preferably, elastic component uses spring, and it is set in outside pin rod.
Preferably, slot internal diameter matches with handle insertion section external diameter.
Preferably, when handle is inserted in slot, slide guide is facing to slot opening direction；Pulled out when by handle out of slot
When going out, slide guide is facing to slot bottom.
Preferably, pin rod is interference fitted with bearing inner race.
Preferably, pin rod is slidably matched with through hole.
In the present invention, the jack proposed presses hand modular construction with automatic spacing, by setting up bearing on alignment pin
And elastic component so that alignment pin and bearing axial restraint, and elastic component both ends are respectively with bearing and pressing hand body and being connected, so
While ensureing that alignment pin is connected with pressing hand body, only by rotary positioning pin, so as to set its slide guide face so that work as handle
When inserting slot, promote alignment pin to be stretched along through hole by slide guide face, realize the locking of alignment pin and handle neck, and ought make
After end, slide guide face is rotated into 180 degree, promotes alignment pin to stretch again by slide guide face, realizes that handle is extracted out from slot.
Hand modular construction is pressed with automatic spacing by the jack of above-mentioned optimization design, simple in construction, reasonable in design, staff only needs
Rotate pin rod with adjust slide guide facing to, you can realize that handle is fixed or departed from stopper slot, handle can is from pressing hand
Easily fixed or extraction in body, hand screw is pressed without turning by hand, simple to operate, laborsaving, efficiency high, and rational in infrastructure, is moved
Make reliability height, can ensure that safe to use, while process that simple, cost is low.
Brief description of the drawings
Fig. 1 is the structural representation that a kind of jack proposed by the present invention presses hand modular construction with automatic spacing.
Embodiment
As shown in figure 1, Fig. 1 is the structural representation that a kind of jack proposed by the present invention presses hand modular construction with automatic spacing
Figure.
Reference picture 1, a kind of jack proposed by the present invention press hand modular construction with automatic spacing, including：Press hand body 1,
Handle 2, alignment pin 3；
Press installation portion and handle connecting portion that hand body 1 includes being connected to each other, the one end of installation portion away from handle connecting portion
It is connected with jack, handle connecting portion has the slot extended from end to installation portion direction, socket side away from installation portion one end
Wall is provided with through hole, and the through hole is L1 close to installation portion one end distance away from slot；
Handle 2 includes the Handheld Division and insertion section being sequentially connected, and insertion section side wall is provided with annular slot, and insertion section is remote
Handheld Division one end to the distance of annular slot is L2, L2 ＜ L1；
Alignment pin 3 includes the pull head 31 and pin rod 32 being sequentially connected, and for pull head 31 positioned at pressing outside hand body 1, pin rod 32 is remote
