Moreover, such as Taiwan Wise property office patent announcement number No. 243042 a kind of structure improvement of pivot device of exposure, especially refer to a kind of pivot device that can adjust elasticity with different loads, it mainly lies in the taper axle sleeve that a spindle rod one end forms the tool opening, this axle sleeve system is hollow shape, and be formed with screw thread in outer rim, axle sleeve is coated with a packing ring outward again, an end is formed with interior inclined-plane in this packing ring, end then is a screw thread in addition, screw togather mutually with axle sleeve, again behind the sheathed elastic component of a paraxial rod one end, be set in the axle sleeve of spindle rod, can adjust the level of compression of facing elastic component in the axle sleeve by packing ring subsequently, and then regulate main, elasticity when pivoting between paraxial rod.

So, in the above-mentioned known techniques, be mostly by a degree of tightness controlling mechanism, when pivoting, pivot device can adjust degree of tightness power, and therefore, known pivot device is in the operation of adjusting degree of tightness power, and inconvenience.So this creator proposes a kind of regulating type resistance shaft based on research and development and many practical experience for many years, with variable in implementation and the foundation of adjusting elasticity as another kind.

The model utility content

Because the problem of above-mentioned prior art, the purpose of the utility model is providing a kind of regulating type resistance shaft exactly, and general resistance shaft must add elastic component so that adjust the problem of the torsion of resistance shaft to solve.

Edge is, for reaching above-mentioned purpose, discloses a kind of regulating type resistance shaft according to the purpose of the utility model, and it has a packing screw, a main shaft body of rod and a noncoupled axle body of rod.One of main shaft body of rod end is the main shaft sleeve of a hollow shape, and wear one positioning hole on the main shaft sleeve, use for positioning piece and penetrate in the main shaft sleeve, and the fixed random noncoupled axle body of rod is inserted in the interior packing screw of main shaft sleeve, one of noncoupled axle body of rod end is hollow and the noncoupled axle axle sleeve that is oblique cone shape, and noncoupled axle axle sleeve noncoupled axle axle sleeve inboard then becomes shape of threads to screw togather with the packing screw.

From the above, because of the regulating type resistance shaft that can adjust the torsion function according to having of the utility model, it can have one or more following advantage:

(1) this regulating type resistance shaft can carry out the elasticity adjustment by spindle rod, noncoupled axle bar and packing screw, can improve the convenience of resistance shaft torsion by this.

(2) but this regulating type resistance shaft mat spindle rod, noncoupled axle bar and packing screw carry out the elasticity adjustment, can solve by this because torsion is different needs all to make again at every turn, and causes the problem of manpower and materials waste.

Now by making your juror further understanding and understanding be arranged to the technical characteristics of the utility model and the effect that reached, careful assistant with preferable embodiment and cooperate detailed explanation as after.

Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments:

Hereinafter with reference to correlative type, the embodiment according to the regulating type resistance shaft of the utility model is described, to be convenient to understand for making, the same components system among the following embodiment illustrates with identical symbology.

Please consult Fig. 1 and Fig. 2 simultaneously, it is the STRUCTURE DECOMPOSITION schematic representation and the textural association perspective view of the regulating type resistance shaft of the utility model.Among the figure, regulating type resistance shaft 100 comprises a main shaft body of rod 110, a packing screw 120 and a noncoupled axle body of rod 130.One of main shaft body of rod 110 end is the main shaft sleeve 111 of a hollow shape, and has the positioning hole of digging through 112 on the main shaft sleeve 111, be inserted in the interior packing screw 120 of main shaft sleeve 111 for the positioning piece 2 fixed random noncoupled axle bodies of rod 130, one of noncoupled axle body of rod 130 end is the noncoupled axle axle sleeve 131 of a hollow shape, noncoupled axle axle sleeve 131 is provided with a plurality of
