The utility model comprises handle, volute spring, handle stop means, strain signal harvester and base.Base is a disk-shaped structure, and the handle stop means of tubular is fixedly installed on the end face of base.A helical spring end that is arranged in the handle stop means tube is fixedlyed connected with the end face of base, and the other end is fixedlyed connected with the inboard end face of the handle of drum shape.Handle is nested with outside the handle stop means, and the lateral wall of the madial wall of handle and handle stop means has the gap, and handle can be movable in this interstice coverage; The top of handle stop means is higher than the bottom of handle, guarantees that handle can not shift out outside the handle stop means.Be distributed with the individual resistance strain gage group of n (2≤n≤4) on the volute spring, each resistance strain gage group comprises that three resistance strain gages are right, and each resistance strain gage is to comprising corresponding two resistance strain gages that are provided with.Three resistance strain gages of each resistance strain gage group are to being arranged within the same spiral circumference of volute spring, and three corresponding in each resistance strain gage group resistance strain gages are identical to the position on the spiral circumference, and two adjacent resistance strain gage groups are at least one spiral circumference at interval.

Described helical spring spring silk cross section is a rectangle; A slice in two resistance strain gages of each resistance strain gage centering is the biaxial strain sheet, be pasted on the lower surface of spring spring silk, and its sensitive grid becomes with spring silk axis ± 45 ° of directions; Another sheet is the uniaxial strain sheet, sticks on the medial surface of spring spring silk, and its sensitive grid and spring silk parallel axes.Three resistance strain gages in resistance strain gage group are respectively 135 °, 135 ° and 90 ° to the angle of projection on the spring circumferential plane.

Described each resistance strain gage all links to each other with strain signal harvester in being arranged on base by signal wire.

The beneficial effect that the utlity model has is:

(1) the utility model device has six degree of freedom input and control ability and has two kinds of duties, be displacement and corner amount input state and power and torque amount input state, this two states can work alone also can hybrid working, all can be set and switches according to the needs of the software that is driven.

(2) because the displacement of mouse is a relative motion amount, can pass through software setting, make when handle arrives the sports limiting boundary position, the displacement of its output is relevant with the application time of acting force with the size of power, the size that is displacement and power is directly proportional with application time, thereby reaches the size control to input quantity.

(3) by shift knob is set on handle, make that this device can be arranged to not have signal output when operator's release handle, promptly be not applied in power and in the process in original position, do not have signal output by self spring return at spring, thereby avoided the location restore action of the mouse of prior art, promptly need be by the manual rolling mouse of operator under the motionless situation of cursor on the computer screen, thus the operational motion of operator reduced to mouse.

(4) because action principle is different with the prior art mouse, also need not do big moving to the input of big displacement quantity, realizing that the operational motion quantity to input media also reduces than the mouse of prior art under the said function situation, therefore use this device can reduce the fatigue strength of operator's hand greatly.

(5) the utility model device total system is simple in structure, and is cheap for manufacturing cost, easy to use, and higher reliability and stability are arranged.
