Crank 42 is rotated, 41 rear end of rotation torsion bar is vertically located at.
Specifically used method:
It is described intelligence duplicate rows formula electric power overhaul with expansion provision for disengagement application method the following steps are included:
Step 1, periphery is cleared up:
It holds the outer cover body 11 and is inserted into other fingers in addition to thumb in the intervention hole of hand-held stringer board 15;
The reset lever 25 compressed spring 25d effect, which is retracted in described, under normality sets in sliding chamber 12a, expands at this time Side plate 24 is in the posture close to the outer cover body 11;The driven screw 23 all bounces back to corresponding driving screw hole 22a Interior, a pair of expansion 24 upper end of side plate inclination is in " eight " font;
Position to be dismounted is inserted into a pair of expansion 24 upper end of side plate, a pair of expansion side plate 24 is isolated by the barrier of surrounding It opens;
Step 2, expansion side plate 24 rotates:
Annulus 21a is stirred described in thumb wheel and then the active worm screw 21 is driven to rotate, described in further driving Driven worm gear 22 rotates;Since driven 22 axial sides of worm gear are respectively equipped with driving screw hole 22a and two driving screw holes Being threaded into for 22a is contrary, and a pair of driving screw hole 22a respectively drives corresponding driven screw 23 away from each other, drives one First plug 23a is located remotely from each other;
At the same time, the reset lever 25 compressed spring 25d effect, which is retracted in always in described, sets in sliding chamber 12a, The expansion side plate 24 rotates under the action of the first plug 23a around the second plug 25a;
Since the upper end is far from outer cover body 11 in 24 rotation process of expansion side plate and lower end is close to outer cover body 11, Stop after the expansion side plate 24 is resisted against on the limit lower beam 25b, the expansion side plate 24 is perpendicular to corresponding at this time Reset lever 25, the expansion side plate 24 complete preliminary expansion;
Step 3, expansion side plate 24 is mobile:
The annulus 21a that stirs, which is continued to rotate, with thumb drives the rotation of active worm screw 21 in turn, it is further to drive The driven worm gear 22 rotates;Since driven 22 axial sides of worm gear are respectively equipped with driving screw hole 22a and two drivings Being threaded into for screw hole 22a is contrary, and a pair of driving screw hole 22a drives the driven screw 23, the first plug 23a to do mutually Separate movement;
The first plug 23a drives expansion 24 upper end of side plate to do the movement far from outer cover body 11, the expansion side plate 24 drive reset levers 25 overcome the compressed spring 25d far from mobile, the expansion to the direction far from the outer cover body 11 Side plate 24 is opened to complete further to expand;
Step 4, adjustment observation casing 3:
The position that the driving nut 32 adjusts the male-pipe 31 is rotated, so that 31 upper end of the male-pipe is close The bolt or screw for needing to dismount;
Step 5, assembling-disassembling bolt or screw:
Step 5.1, connection is completed:
Moving the disassembly handle 4 with hand push is set in the Hexagon hole 41a on bolt, and the bolt acts on spiral shell Silk cutter head 41e is pushed;
Or the disassembly handle 4 is moved with hand push and is made on the driver bit 41e insertion screw;
Step 5.2, rotation crank 42 is dismounted:
The rotation rotation crank 42 drives rotation torsion bar 41 to rotate;
Pass through Hexagon hole 41a assembling-disassembling bolt;
Or screw is dismounted by driver bit 41e.
Taking the above-mentioned ideal embodiment according to the present invention as inspiration, through the above description, relevant staff is complete Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention Property range is not limited to the contents of the specification, it is necessary to which the technical scope thereof is determined according to the scope of the claim.
