The extraction assembly comprises a rolling wheel a, a rod piece a, a rolling wheel b and a rod piece b; the rolling wheel a is hinged to one end of a handle through the rod piece a; the range of the external diameter of the rolling wheel a is greater than any outer contour on an end portion of the handle; the middle of the handle is hinged to a plate clamp through the rod piece b; the rod piece b penetrates the rolling wheel b which is arranged between a hinged position of the handle and the plate clamp. The extraction tool has the rapid extraction function, is high in service life and reliable in safety performance.
Description
Technical field
The utility model relates to military project mechanical device instrument field, particularly a kind of have help fast the driver-extractor that pulls out function.
Background technology
The pull-up of existing plug board, comprise: handle, a pusher dog, straight pin, handle is connected with board by straight pin, handle be take straight pin and is used lever principle to realize rising of driver-extractor to pull out function by playing pusher dog and machine box surface as rotating shaft, and design exists certain potential safety hazard like this: straight pin easily comes off in vibration environment, handle and board has certain frictionally damage board face, a pusher dog utilization lever principle has certain frictionally damage to machine box surface; Prior art greatly reduces service life of equipment, has limited device security performance, and in the plate design of communication apparatus or electronic equipment, application can not get certainly.
Utility model content
The problem existing for prior art, goal of the invention of the present utility model be to provide a kind of have to help fast pull out function, high service life, the reliable driver-extractor of security performance.
To achieve these goals, the technical solution adopted in the utility model is:
, it comprises handle, rises and pull out assembly, and described is pulled out assembly and comprises: roller a, rod member a,
Described roller a is hinged on described handle one end by rod member a, and the external diameter scope of described roller a is greater than any outline of described handle end.
As preferred version of the present utility model, described is pulled out assembly and also comprises: roller b, rod member b, and described handle middle part is articulated with on a board by rod member b, and described roller b is passed and is arranged between described handle and described board hinged place by described rod member b.
As preferred version of the present utility model, described roller a turns over riveting by rivet a and is hinged on described handle one end.
As preferred version of the present utility model, described handle middle part is turned over riveting by rivet b and is articulated with on a board.
As preferred version of the present utility model, on described handle, one end of not hinged roller a is provided with and pulls parts.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
1, rising after described improvement pulled out assembly the damage of machine box surface reduced greatly, improved service life, improved efficiency.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
A kind of driver-extractor, it comprises handle 7, rises and pull out assembly, described is pulled out assembly and comprises: roller a1, rod member a2, described roller a1 is hinged on described handle 7 one end by rod member a2, and the external diameter scope of described roller a1 is greater than any outline of described handle 7 ends, and described roller a1 can rotate in installation place, to realize driver-extractor and machine box surface, be to roll to contact, greatly simple friction, has improved driver-extractor service life, has improved efficiency.
In embodiment of the present utility model, described is pulled out assembly and also comprises: roller b3, rod member b4, described handle 7 middle parts are articulated with on a board 6 by rod member b4, described roller b3 is passed and is arranged between described handle 7 and described board 6 hinged places by described rod member b4, after adding roller b3 between handle 7 and board 6, reduce frictionally damage, improved service life.
In embodiment of the present utility model, described roller a1 turns over riveting by rivet a and is hinged on described handle 7 one end, has saved process costs, material cost reaching in required object situation.
In embodiment of the present utility model, described handle 7 middle parts are turned over riveting by rivet b and are articulated with on a board 6, and the straight pin structural design compared with in the past, makes driver-extractor more stable, has improved the security performance of equipment.
In embodiment of the present utility model, on described handle 7, not hinged roller a1 one end is provided with and pulls parts 5, and handled easily person lifts driver-extractor.
During the running of described driver-extractor, pull to pull parts 5 on described handle 7, described roller a1 acting in opposition, on cabinet slide rail, can take out described board 6 pull-ups by lever principle.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
