Embodiment

See also " Fig. 5 to Fig. 7 ", the utility model string of a musical instrument tightness is adjusted structure, comprises:

One pedestal 10, what a circle was established in these pedestal 10 inside is installed with space 11, this is installed with space 11 can lead to this pedestal 10 tops, and have and hold edge 12 and be positioned at the top that this is installed with space 11, these pedestal 10 belows are extended the body 13 of a circle downwards, one room 14 is installed with 11 sides, space for laterally being positioned at this, can be installed with space 11 with this communicates, the front and back wall of this room 14 is established a pair of circular hole 141, the cover plate 15 of one circle, this cover plate 15 are that lid is located at this and holds on the edge 12, this can be installed with space 11 and seal, a pair of slot 16 is established in the front and rear wall inboard of this room 14, and this slot 16 is can lead to these pedestal 10 bottoms and form an opening.

One scroll bar 20, these scroll bar 20 inside are to be hollow can pierce into this body 13, a corner post 21 is established in its upper end, a line hole 22 is laterally established in the below, this line hole 22 is that an end of the string of a musical instrument (figure does not show) of confession one stringed musical instrument such as guitar passes and tie up solid, one worm gear 23, these worm gear 23 centers are established a polygonal hole 231 can be for corner post 21 fits of this scroll bar 20.

One knob 30, these knob 30 1 ends are the handles that are flat-shaped, and the other end extends a worm screw 31, and this worm screw 31 can pierce on two circular holes 141 of this pedestal 10, two recessed necks 32 are established in these worm screw 31 front and back, and this worm screw 31 is to rotate to drive this worm gear 23 with these worm gear 23 engagements.

The shell fragment 40 of one U-shaped, extend upward a pair of intermediate plate 41 before and after it, this intermediate plate 41 is by protruding towards inner arc outward, and its apical margin formation shape wave that extends outwardly slightly, and there is a recessed edge 42 to be positioned at this intermediate plate 41 tops, this is can pack into the slot 16 of this pedestal 10 and gripped fastening by this slot 16 to intermediate plate 41, and this recessed edge 42 is the recessed necks 32 that pack in this worm screw 31, and this worm screw 31 is linked with pedestal 10.

By above-mentioned structure, desire is regulated the elasticity of this string of a musical instrument, the handle of then holding this knob 30 can drive this worm screw 31 forward and reverse rotations, to drive this worm gear 23 rotations, and these scroll bar 20 corner posts 21 are polygonal hole 231 fits with worm gear 23 centers, can drive this scroll bar 20 rotations, and these scroll bar 20 upper ends are that the mat gravitational pressing makes these scroll bar 20 upper ends expand and be connected with this worm gear 23 outwardly, therefore making worm gear 23 can drive this scroll bar 20 rotates synchronously, but the rolling-in winding on scroll bar 20 the string of a musical instrument or loosen, and this worm screw 31 turns around and can make worm gear 23 rotate a tooth, so can reach fine setting string of a musical instrument tightness purpose.

Importantly, the utility model is the slot 16 that is inserted in pedestal 10 by the intermediate plate 41 of shell fragment 40 shape waves, and gripped the location by slot 16, utilize the recessed edge 42 of shell fragment 40 to be inserted in the recessed neck 32 of worm screw 31 again, this knob 30 is fixed on the pedestal 10, roll up the device structure shown in " Fig. 1 " compared to known guitar string, can save two screw 5b and screw 7, two pads reach the trouble that processes the group cover 5a of portion on two planes at the end of worm screw 5, therefore have assembly simple in structure and be easy to advantage, and can reduce manufacturing cost and meet economic benefit.

In sum, the utility model is made sample as patent specification and graphic content, and really can reach its desired purpose and effect through the proof of use test repeatedly, the exploitation that practicality has much market is worth, and the whence proposes patented claim according to the regulation of Patent Law to an ancient unit of weight office.

The above person of thought, it only is preferred embodiment of the present utility model, when can not with the scope implemented of qualification the utility model, promptly the equalization of being done according to the utility model claim generally changes and modifies, and all should still belong in the scope that the utility model patent contains.
