[0017] The utility model will be further described in combination with the description and specific implementation of the drawings:

[0018] As Figs. 1 to 4 shown, the embodiment of the utility model preferably provides a tone arm with lifting and slow placing functions, which comprises a tone arm seat 1, a tone arm body 2 arranged on the tone arm seat 1, a tone arm frame 3 for supporting the initial position of the tone arm body 2, a lifting part 4 arranged on the tone arm seat 1 and used for lifting the tone arm body 2, a controller 5 used for controlling the lifting amplitude of the lifting part 4, and an elastic device 6 used for slowly placing the tone arm body 2, wherein an extension rod 7 is arranged on the lifting part 4 and used for supporting the tone arm body 2. The initial position of the tone arm body is placed on the tone arm frame, when the tone arm head needs to contact the black vinyl record, the controller can be used to lift the lifting part, then the tone arm body is moved to the position where the tone arm head is aligned with the record, after the controller is reset, the elastic device can slowly lower the tone arm body until the tone arm body is placed on the record. The connection relationship between the tone arm body and the tone arm seat is the prior art, the tone arm body can freely rotate forward and backward and swing up and down on the tone arm seat, so that the activity of the tone arm body can finally place the tone arm head on the record.

[0019] The lifting part 4 in the utility model comprises a groove 41 arranged on the tone arm seat 1 and penetrating the upper wall, a pressing block 42 arranged in the groove 41 and used for pressing the tone arm body 2, and a slope 43 arranged at the bottom of the pressing block 42. The groove can make the pressing block extend out of the tone arm seat, and the groove can limit the pressing block to move up and down only. The slope at the bottom of the pressing block is used for enabling the controller to push the pressing block to move upward.

[0020] The extension rod 7 is arranged on the top of the top pressing block 42 and opposite to the controller 5. The extension rod is used to support the body of the record arm during the rotation to the side of the vinyl record, until the stylus is aligned with the sound source playing position of the vinyl record, and then the extension rod is lowered with the slow release of the top pressing block, and the body of the record arm is supported during the period, so that the record arm is inclined downward, and the stylus is placed on the record.

[0021] The controller 5 comprises a supporting seat 51 arranged below the groove 41, a control rod 52 is hinged on the supporting seat 51, and a protruding part 53 for upwardly pushing the top pressing block 42 is arranged on the control rod 52. The control rod can be pushed forward and backward by hand, and in the technical solution, the control rod is pushed backward to make the control rod stand up, and at this time, the protruding part is in a state of upwardly pushing the top pressing block, so that the body of the record arm is turned upwardly during the upward movement of the top pressing block. Conversely, the control rod is pushed forward to make the control rod in an inclined state, and the protruding part is separated from the inclined surface of the bottom of the top pressing block, and the body of the record arm is turned downwardly while the top pressing block is moved downwardly.

[0022] The protruding part 53 is attached to the inclined surface 43, so that the control rod can drive the protruding part to slide on the inclined surface and push the top pressing block upwardly in the state of being inclined and standing up.

[0023] The elastic device 6 comprises a concave tube 61 arranged on the front side of the record arm seat 1, a reset rod 62 is arranged on the front side of the top pressing block 42 and inserted into the concave tube 61, a pressing sheet 63 is arranged on the bottom of the reset rod 62, and a tension spring 64 is arranged between the top wall of the pressing sheet 63 and the bottom wall of the concave tube 61. During the downward movement of the top pressing block, the reset rod moves downwardly, and the speed of the downward movement is slowed down by the elasticity of the tension spring, so that the slow release of the stylus is realized.

[0024] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above, and the person skilled in the art should understand that the utility model is not limited by the above-mentioned embodiments, and the above-mentioned embodiments and the description in the specification are only used to illustrate the principle of the utility model, and various changes and improvements of the utility model can be made without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed. The protection scope of the utility model is defined by the appended claims and their equivalents.
