A kind of specific embodiment of the invention provides a kind of operation handle, including：Support 1, handle 2,3 and of gas spring
Secondary spring 4, wherein gas spring 3 includes cylinder barrel 31, piston 33 and piston rod 34 and piston-rod lower end 35；The bottom end of handle 2
Hinged by the first articulated shaft 5 and support 1, wherein the upper end of handle 2 is equipped with hand-held part 22, and the lower part of handle 2 is equipped with chamber 21,
21 inner top of chamber is equipped with inverted U slot, and the cylinder barrel upper end of gas spring 3 is against in inverted U slot, the piston-rod lower end 35 of gas spring 3
It is hinged on support 1 by the second articulated shaft 6, rotates predetermined angle with handle 2, while after gas spring 3 is compressed, secondary spring
4 generate screen resilience, with the revolution of assist handle 2.Wherein in order to limit the rotational angle of handle 2, support 1 is equipped with limiting component 8,
The limiting component 8 can be the stop screw being threaded on support 1, and 2 bottom of handle is equipped with and the stop screw phase interworking
The limiting slot of conjunction.
In the present embodiment, by secondary spring 4, handle can be increased on the basis of not changing 3 compressing force of gas spring
2 restoring force can reduce the requirement of 3 nominal pressure of gas spring and dynamic internal resistance, reduce the working strength of operator, in addition assist
Spring 4 can feed back a kind of feel pressed down with compression travel increase to operator, and not only increase operator uses body
Effect is tested, can also reduce impact of the operation handle 2 to limiting section, and then play protective action, that improves operation handle 2 uses the longevity
Life.
Wherein secondary spring 4 can be the compressed spring of axial stretching, or torsional spring 7, when for compressed spring,
Can be there are two types of mounting means, one compressed spring is set in outside the piston rod 34 of gas spring 3, and can rotate preset angle in handle
It after degree, is stretched with the stretching, extension of gas spring 3, compresses and compress；Secondly compressed spring is located at the interior of the cylinder barrel upper end 32 of gas spring 3
In the space constituted between top and 33 top of piston of gas spring 3, secondary spring 4 is after handle rotates predetermined angle, with gas
The stretching, extension of spring 3 and stretch, compression and compress.
Specifically, there is no precommpression when compressed spring original state, bullet can just be compressed by rotating to certain angle in handle 2
Spring, during operator's control crank 2 rotates clockwise, the position of handle 2 will appear two limiting cases, and handle 2 is initial
The terminal position that position and handle 2 press down, corresponding 3 state of gas spring is just to start compression and handle 2 respectively at this time
Rotation predetermined angle is compressed to bottom.
Wherein there is following two process in the movement of control crank 2：Compression process, operator's control crank 2 is from initial position
Starting to move in a circle makes handle 2 be depressed into mechanical position limitation to reach terminal position；Stretching process, operator discharge from terminal position
Handle 2 makes handle 2 bounce back into initial position automatically under the action of gas spring 3 and secondary spring 4.
In order to better understand beneficial effects of the present invention, force analysis next is carried out to operation handle 2, operator exists
2 point of application of handle is C, and the distance of the first articulated shaft of distance 5 is D, and applied force Fr, 2 gravity of control crank is G, position of centre of gravity
In B point, the distance of the first articulated shaft of distance 5 is L, and 3 expansion force Fs of gas spring, compressing force Fy, the elastic force of secondary spring 4 is f, bullet
Property element, that is, gas spring 3 and the resultant force F of secondary spring 4 be l away from the distance of the second articulated shaft 6 to the point of application A of control crank 2,
There is following relationship：L ≈ 2l, handle 2 rotate clockwise predetermined angle under the action of operator, around the first articulated shaft 5, such as
45 ° of rotation starts to compress secondary spring, rotates 60 ° of stoppings, and each variable has following relationship：
Fn is component of the elastic force F along the direction OA and the vertical direction OA respectively with Ft：
Ft=F sin α
Gn is component of the gravity G along the direction OB and the vertical direction OB of handle 2 respectively with Gt：Gt=G sin β
The elastic element of handle 2 is supplied to the counterclockwise rotating force square of handle 2：Mt=F sin α l
The gravity of handle 2 itself is supplied to the turning moment of handle 2：Mg=G sin β L
The power that operator applies is supplied to the right-handed moment of handle 2：Mr=FrD
Initial position：α and β corner connection is close and all very littles, sin α ≈ sin β
Terminal position：The angle β reaches maximum value, sin β ≈ 6sin α
For the resultant force F of elastic element, the F=F in gas spring compression processy+ f, the F=F in gas spring stretching processs+
f
Control crank 2 rotates clockwise 60 ° under the action of operator, around the first articulated shaft 5, because gas spring 3 is with handle 2
It rotates and is compressed, initial position incrementss very little is compared at the angle α, can be ignored, but the gravity direction of control crank 2 is always
Straight down, the angle β increases very much, and the angle β increases corresponding angle around the angle that the first articulated shaft 5 rotates clockwise with handle 2.
Compression process：In initial position, secondary spring is not compressed：
F=F at this timey, sin α ≈ sin β
By moment equilibrium condition；Mr+Mg=Mt, i.e. FrD+G sin β L=F sin a l；
Due to L ≈ 2l, so Fr=l/D (Fy-2G)sinα；
The compressing force F of gas spring 3yThe bigger power for needing operator to provide is bigger, the easier fatigue of operator, and when auxiliary
When spring starts to be compressed, F=F at this timey+ f, as the increase f of secondary spring decrement is gradually increased, F is also obviously increased, and is made
It obtains the feel that operator pushes and becomes weight, give a kind of feel limited near bottom of operator, and bottom limit can be reached in handle
Play the role of certain buffering when position.
Stretching process：The structure can normally spring back to meet handle 2, it is necessary to meet the following conditions：
By moment equilibrium condition Mt=Mg, i.e.,：F sin α l=G sin β L, i.e.,：F=2lG sin β/sin α, in summary
Condition is it is found that the angle β reaches maximum when terminal position, and F is maximum, and secondary spring is also compressed state at this time, by F=Fs+f,
The power f that wherein secondary spring provides is bigger, appropriate, stretching force F to be offered needed for gas springsCan be smaller, thus right
The requirement of gas spring power is also just smaller.
