The gear teeth be meshed with the tooth bar being arranged on second body sidewall, described tooth bar is installed in guide rail.
Using said structure, the nut of anode stub is positioned in fixed part, the interior table of the outline of nut and fixed part
Facial contour is fitted completely, and such as nut is hex nut, then the inner surface profile of fixed part be corresponding with nut and identical
Hexangle type, then starts cylinder, the piston rod band moving gear on cylinder and rack work, rack drives compressed part prolonging to nut
Stretch section to move and compress, gear driven anode stub rotates in a circumferential direction simultaneously, thus realizing the compression to extension circumference it is ensured that extending
The barred body of section and anode stub is tightly combined, smooth and good airproof performance at sealing；Abandon the defect of conventional ones mode band.
Preferably, described groove is circle, described compressed part is three, circumference is uniformly arranged in groove, position
Compressed part in top is connected with the piston rod of cylinder by sliding bar, and described sliding bar passes through connecting rod with tooth bar even
Connect and be synchronized with the movement；Using this structure it is ensured that in compression, the barred body of sealing nut extension and anode stub, stress equal
Even, whole week uniform stressed, the product of acquisition has more preferable flatness and sealing.
Preferably, being provided with positioning wedged block on the piston rod of described cylinder, gear band be can ensure that using this structure
The number of turns that the rotation of dynamic fixed part is specified, such as when compressed part be three, circumference be uniformly arranged in groove, then the setting of positioning wedged block
As long as counting position to ensure fixed part rotation 1/3 circle, you can the compression of the barred body whole week of complete nut extension and anode stub
And density.
Preferably, described compressed part includes the sliding shoe along groove radial expansion, the end of described sliding shoe sets
It is equipped with the scroll box rotating in a circumferential direction, during compressed part clamp nut extension, described sliding shoe contacted with nut extension.Adopt
Use this structure, both can guarantee that extension and barred body compress, ensure that pressed parts are more smooth, smooth simultaneously, good airproof performance.

Specific embodiment
Describe the present invention in detail below by specific embodiment, but the present invention is not limited solely to following examples.
As shown in accompanying drawing 1-2：A kind of nut sealing device of the present invention, this equipment includes the first pedestal 1 and the second pedestal
2, the first described pedestal 1 and the second pedestal 2 are connected by connecting post 3；The top of the first described pedestal is provided with cylinder 4,
The second described pedestal side wall setting fluted 5, is provided with the pressure that can press anode stub nut extension in described groove
Tight portion 6 and the fixed part 7 that anode stub nut can be placed；It is provided with gear 8 on the second described pedestal and groove opposite side wall,
Described gear is fixedly connected and can rotate in a circumferential direction (driving fixed part to rotate in a circumferential direction) with fixed part；It is provided with described gear
The gear teeth, the described gear teeth are meshed with the tooth bar 9 being arranged on second body sidewall, and described tooth bar is installed in guide rail 10；
