That is, head 242 and extension 241 can be stair-stepping, and preferably head 242 and extension 241 in parallel plane.

Therefore, elastic component 260 is in the side that 242 extruding is from the head just supported fastenings 240 after discharging, and it prevents to be fixed to weight balancing spare 80 rotation in settling groove 22 of cylinder 20 simultaneously.

Simultaneously, also can in settling the rear surface of groove 22, provide covering 270 to be fixed to the inner space that is exposed to cylinder 20 under the state of cylinder 20 at weight balancing spare 80 to prevent elastic component 260 and head 242.

Settle the rear surface of groove 22 can be corresponding to the inner surface of cylinder 20, the clothing of cylinder 20 be damaged by elastic component 260 and head 242 thereby covering 270 can prevent to pack into.

Here, preferably the rear of covering 270 and insertion portion 251 and channel part 252 to spaced a predetermined distance from, so that fastenings 240 can insert and rotate.

Fixation procedure between weight balancing spare 80 and the cylinder 20 will be described as follows.

At first, the head 242 of fastenings 240 is inserted in the insertion portion 252 of fastener hole 250.

Therefore, weight balancing spare 80 is positioned in to be settled in the groove 22, and elastic component 260 pushes by the elasticity of head 242, so that fastenings 240 can be fixed along the passage of its rotation.

Therefore, weight balancing spare 80 is along channel part 152 rotations.In case weight balancing spare 80 rotates to fully when the end location of channel part 252, the extension 241 of fastenings 240 closely contacts with the terminal of channel part 252.

At this moment, elastic component 260 242 extruding from the head discharges, and it is owing to fastenings 240 is supported in its recovery, so that weight balancing spare 80 is completely fixed to cylinder 20.

Here, for preventing weight balancing spare 80 since the rotation of cylinder 20 and vibrations along cylinder 20 forward and direction backward move, the degree of depth that extension 241 may extend to fastener hole 250 is so long, promptly settles the thickness of groove 22 so long.

Therefore, can prevent to move under the state of weight balancing spare 80 in being placed in the arrangement groove 22 of cylinder 20.

A plurality of above fastenings 240 can be arranged in the rear surface of weight balancing spare 80, and these fastenings can be located about the center of weight balancing spare 80 with being mutually symmetrical.Therefore, only when one of fastenings corresponding to fastener hole one, weight balancing spare 80 could be fixed to cylinder 20 smoothly.

It will be apparent for a person skilled in the art that and to make various modifications and variations and not deviate from the spirit or scope of the present invention the present invention.Thereby the present invention is intended to contain all such modifications of the present invention and variation, as long as they drop in the scope of appended claims and equivalent technique scheme thereof.
