[0023] A positioning mechanism 5 is installed on the upper surface of the phonograph body 2, a guide rod 6 is connected to the inner wall of the phonograph case 1 that passes through the phonograph body 2, a first spring bar 7 is connected between the phonograph body 2 and the phonograph case 1, a bearing 8 is embedded and installed on the surface of the phonograph case 1, a bidirectional screw rod 9 is connected to the inside of the bearing 8, the bidirectional screw rod 9 passes through the transverse block 10, the surface of the transverse block 10 is connected to the extrusion block 11, and an adjustment groove 12 is provided on the surface of the phonograph body 2 near the extrusion block 11.

[0024] Preferably, an elastic telescopic structure is formed between the phonograph body 2 and the first spring bar 7 .

[0025] During specific use, when the phonograph housing 1 is hit, it can drive the guide rod 6 to slide inside the phonograph body 2 and squeeze the first spring bar 7. The first spring bar 7 can be cushioned by its own elastic force when being squeezed, thereby achieving an anti-collision effect.

[0026] Preferably, the bidirectional screw rod 9 and the lateral movement block 10 are connected by threads, and a rotating structure is formed between the bidirectional screw rod 9 and the bearing 8 .

[0027] During specific use, when the bidirectional screw rod 9 rotates, it can drive the lateral movement of the lateral movement block 10 through the threaded connection relationship, and the lateral movement of the lateral movement block 10 can drive the extrusion block 11 to move laterally.

[0028] Preferably, the positioning mechanism 5 comprises a clamping block 501, a second spring bar 502, a positioning block 503, a guide slider 504 and a guide slot 505, the clamping block 501 is mounted on the upper surface of the phonograph body 2, the side surface of the clamping block 501 is connected to the second spring bar 502, the bottom of the second spring bar 502 is connected to the positioning block 503, the side surface of the positioning block 503 is connected to the guide slider 504, and the surface of the clamping block 501 close to the guide slider 504 is provided with a guide slot 505.

[0029] During specific use, the positioning block 503 moves upward to compress the second spring strip 502. When the support rod moves to the inside of the arc groove of the clamping block 501, the second spring strip 502 squeezes the positioning block 503 downward through its own elastic force and resets it, so that the position of the cartridge bracket 4 can be fixed.

[0030] Preferably, an elastic telescopic structure is formed between the positioning block 503 and the second spring strip 502 .

[0033] Working principle: When the phonograph with the anti-collision structure is used, the support rod of the cartridge support 4 can be rotated when the phonograph stops working. When the support rod moves to the side surface of the positioning block 503, the positioning block 503 is squeezed and can drive the guide slider 504 to slide upward inside the guide slide groove 505. The upward movement of the positioning block 503 can compress the second spring bar 502.

[0034] When the phonograph is transported, the cover of the phonograph housing 1 can be closed and locked first, and then the bidirectional screw 9 can be rotated. When the bidirectional screw 9 is rotated, it can drive the lateral movement of the transverse block 10 through the threaded connection relationship. The lateral movement of the transverse block 10 can drive the extrusion block 11 to move laterally. When the two extrusion blocks 11 move closer to each other, a gap appears between the extrusion block 11 and the adjustment groove 12. When the phonograph housing 1 is hit, the phonograph housing 1 can drive the guide rod 6 to slide inside the phonograph body 2 and squeeze the first spring bar 7. The first spring bar 7 can be buffered by its own elastic force when it is squeezed, thereby having an anti-collision effect.

[0035] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
