Transmission device is provided between sliding knob and anti-slip spring.
A kind of disc machine sound arm shoe as above, it is characterised in that：The transmission device includes and preventing sliding and rotating
The coaxially connected first gear of button and the second gear being fixedly connected with anti-slip spring, between the first gear and second gear
Be engaged with to be the 3rd gear of the two transmission.
A kind of disc machine sound arm shoe as above, it is characterised in that：The second gear is located at sound arm rotating shaft
Between seat and reset push jack, the second gear can be rotated coaxially with respect to sound arm shaft seat and reset push jack.
A kind of disc machine sound arm shoe as above, it is characterised in that：The upper surface of the second gear is located at
Its outer edge is provided with the collar mounting holes seat of protrusion, and described anti-slip spring one end is located in installing hole seat and will by glue
The two is fixed.
A kind of disc machine sound arm shoe as above, it is characterised in that：The reset push jack is provided with push jack through hole,
Described anti-slip spring one end is provided with elastic arm that is protruding and being located in push jack through hole.
Compared with prior art, the utility model has the following advantages：When sound arm is moved, reset push jack can follow sound arm to turn
Dynamic, when sound arm turns to certain position, reset push jack can be contacted in certain position with anti-slip spring, and anti-slip spring is multiple
Elastic deformation is to reset push jack so as to produce a reciprocal elastic force in the presence of the push jack of position, when turning for this elastic force and sound arm
When power is identical, sound arm then keeps balance not to be rotated further by this position.And user can be changed by rotation grip knob
The position of anti-slip spring, therefore, it can be set sound arm by rotation grip knob and turns to certain position and be not rotated further by, from
And there is the function that can be repeated playing.
【Description of the drawings】
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings, wherein：
Fig. 1 is a kind of structural representation of disc machine sound arm shoe of the utility model；
Fig. 2 is a kind of front view of disc machine sound arm shoe of the utility model；
Fig. 3 is along the Section View in I-I directions in Fig. 2.
【Specific embodiment】
The utility model is further described below in conjunction with the accompanying drawings：
A kind of disc machine sound arm shoe as shown in Figure 1 to Figure 3, including sound arm fulcrum bearing 1, the sound arm fulcrum bearing
The 1 sound arm shaft seat 3 that be provided with for stationary tone arm 2 and can rotate relative to sound arm fulcrum bearing 1, the sound arm fulcrum bearing 1
Bottom is provided with the reset push jack 4 coaxially connected with sound arm shaft seat 3, and the bottom of sound arm fulcrum bearing 1 is additionally provided with and can stop reset
The anti-slip spring 5 that push jack 4 is rotated, being provided with the upper surface of the sound arm fulcrum bearing 1 can adjust to the position of anti-slip spring 5
The anti-skidding knob 6 of section, between the anti-skidding knob 6 and anti-slip spring 5 transmission device 7 is provided with.When sound arm 2 is moved, reset is pushed away
Piece 4 can follow sound arm 2 to rotate, and when sound arm 2 turns to certain position, reset push jack 4 can be in certain position and anti-skidding bullet
Spring 5 is contacted, anti-slip spring 5 in the presence of reset push jack 4 elastic deformation so as to reset push jack 4 produce a reciprocal bullet
Power, when this elastic force is identical with the rotatory force of sound arm 2, can make sound arm 2 keep balance not to be rotated further by certain position.Pass through
Rotation grip knob 6, the position of anti-slip spring 5 can be changed in the case where transmission device 7 is acted on, and be therefore, it can by rotation grip
Knob 6 is not rotated further by set sound arm 2 and turn to certain position.
