The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Embodiment one: the electric energy-stored spanner of Vehicular portable formula that the rectifier transformer device is not installed.
Referring to Fig. 1-Figure 11, during the removing vehicle tyres holding screw, end with screw socket is enclosed within on the tightening screw cap earlier, then, hold carrying handle ring 18 on housing 1 stage casing for one, another holds housing 1 back segment push-up handle ring 19, the square toes that make the square toes of rotary main shaft 3 front ends or be connected extension bar 20 front ends on the rotary main shaft 3 insert in the square hole of the screw socket other end, power line 21 is connected with Vehicular accumulator cell, turn on the power switch 16 and make motor 2 rotations, motor 2 drives 4 rotations of disk spline housing; Because an end of the eccentric tube 7 of energy storage clutch cooperates with the outside of disk spline housing 4, the end cap of energy storage clutch cooperates with an end of eccentric tube, the cylinder 10 at clutch block 8 two ends of energy storage clutch cooperates with the hole at eccentric tube and end cap edge, the fixture block 11 of clutch block 8 ends is positioned at the breach 5 on the disk of disk spline housing, so, one side of breach 5 contacts with one side of the fixture block 11 of clutch block 8 ends on the disk spline housing, promptly drive the rotation of energy storage clutch, by action of centrifugal force savings energy, at this moment, clutch block is set upright the interior side contacts of the arc piece 12 of dish 13 in the middle part of its cylindrical and clutch block under the effect of compression spring 14, make it to swing and contact with the circular arc projection 6 of two symmetries on the rotary main shaft 3, an end inserts the endoporus of disk spline housing 4, the rotary main shaft 3 that the leading portion internal axle sleeve 15 of other end housing cooperates does not rotate.After several seconds, the energy of energy storage clutch savings is enough to unload the wheel holding screw.At this moment only need handle ring 19 is pushed ahead, the disk spline housing 4 of rotation promptly moves forward extruding compression spring 14, and the energy storage clutch is moved forward, the arc piece 12 at its clutch block middle part is set upright dish 13 with clutch block and is disengaged, one side of the arc piece 12 at clutch block middle part under action of centrifugal force to lower swing, this side contacts with a circular arc projection 6 on the rotary main shaft 3, a bigger moment of torsion is delivered to rapidly makes it unexpected rotation on the rotary main shaft 3, the wheel holding screw is unloaded down rapidly, generally only needed 2-3 second.If the resistance that runs into is excessive, once can not be successful, the breach of disk spline housing can be set upright clutch block, make it with rotary main shaft on the circular arc projection disengage, reaction force can not be delivered on the energy storage clutch, imperceptible reaction force on carrying handle ring and the handle ring, therefore, as safe as a house.
When the wheel holding screw is installed, only need, motor 2 counter-rotatings are got final product, operate identical with the removing vehicle tyres holding screw with swing reversing switch 17.
Embodiment two: the electric energy-stored spanner of Vehicular portable formula that the rectifier transformer device is installed.
Only need to install a cover rectifier transformer device in housing 1, make it to be connected with power switch, can utilize the AC power in the station, all the other are identical with embodiment one.
