The protection plate can effectively reduce the loosening of the heat sink body caused by external force or human operation error, thereby increasing the stability of the entire installation frame, thereby ensuring the normal operation of the computer during long-term use. The limit plate moves downward to contact the front side of the heat sink body and restores the limit of the heat sink body.

[0016] (2) The computer motherboard CPU heat sink fixing device moves the anti-sway plate toward the heat sink body to contact the anti-sway groove and limit the heat sink body. When the heat sink body is running for a long time, it will produce a small displacement due to vibration and affect its heat dissipation efficiency.

[0018] (4) The computer motherboard CPU heat sink fixing device moves the connecting plate toward the fixing plate to contact the power cord and tighten the contact point between the power cord and the installation frame. By moving and tightening the connecting plate, the contact point between the power cord and the installation frame can be ensured to be firmly connected, thereby avoiding loosening or poor contact of the power cord due to vibration, external force and other factors during use, thereby improving the stability of power transmission.

[0019] (5) The computer motherboard CPU heat sink fixing device moves toward the placement frame by means of the extrusion of the gear on the rack and performs secondary tightening of the power cord, thereby preventing the power cord from being damaged due to excessive pulling. As the pulling force increases, the extrusion force of the rack on the power cord can effectively enhance the tensile strength of the power cord, thereby preventing the cable from being stretched or damaged, thereby extending the service life of the power cord.

The protective plate 12 can effectively reduce the loosening of the radiator body 5 caused by external force or human operation error, thereby increasing the stability of the entire mounting frame 4, and precise docking can ensure that the radiator body 5 is more stable after installation and is not prone to loosening.

[0024] The protection plate 12 contacts the bottom of the protection rod 14, the limiting plate 10 contacts the front side of the radiator body 5, and a No. 1 spring is arranged between the movable plate 7 and the mounting frame 4, through which the movable plate 7 can be driven to reset.

[0025] A clockwork spring 1 is arranged between the protection disk 12 and the limit plate 10, one end of the clockwork spring 1 is arranged at the bottom of the protection disk 12, and the other end is arranged at the top of the limit plate 10. The clockwork spring 1 can drive the protection disk 12 to reset, the bottom of the limit plate 10 is arranged as an inclined surface, and the front side of the U-shaped plate 8 is arranged as an inclined surface.

[0026] When this embodiment is working: when the radiator body 5 needs to be cleaned, the protection plate 12 is manually rotated to rotate. The rotation of the protection plate 12 squeezes the clockwork spring 1, and the clockwork spring 1 is squeezed by the protection plate 12 to produce deformation and accumulate force. At the same time, the protection plate 12 rotates to align the protection groove 13 with the protection rod 14. After the protection groove 13 is aligned with the protection rod 14, the protection rod 14 releases the limit on the protection plate 12. After the limit of the protection plate 12 is released, the limit plate 10 is manually pulled upward. The limit plate 10 moves upward to pull the limit spring 11.

At the same time, after the radiator body 5 moves to its original position, the limit plate 10 moves downward under the elastic force of the limit spring 11, and the limit plate 10 moves downward to contact the front side of the radiator body 5 and restore the limit to the radiator body 5.

[0027] See also Figure 1-Figure 7 On the basis of the above embodiment, in another embodiment of the present invention, an anti-sway component for preventing the radiator body 5 from excessively swaying is provided on the right side of the installation frame 4, and a protective component for preventing the cable from being excessively pulled is provided on the right side of the installation frame 4. The anti-sway component includes a placement frame 151, an anti-sway bar 152, an anti-sway plate 153, an anti-sway groove 154, a deceleration hole 155, a deceleration bar 156 and a deceleration plate 157. A placement hole is provided on the right side of the installation frame 4, the placement frame 151 is fixedly installed on the right side of the installation frame 4, the anti-sway bar 152 slides through the inner and outer walls of the placement frame 151, the anti-sway plate 153 is fixedly installed on the left side of the anti-sway bar 152, the anti-sway groove 154 is provided on the right side of the radiator body 5, the deceleration hole 155 is provided on the right side of the placement frame 151, the deceleration bar 156 is rotatably installed on the inner wall of the deceleration hole 155, and the deceleration plate 157 is fixedly installed on the circumferential surface of the deceleration bar 156. The design of the anti-sway plate 153 and the anti-sway groove 154 keeps the radiator body 5 in the best contact position, thereby maximizing the heat dissipation effect of the radiator body 5.

[0028] A second clockwork spring is arranged between the deceleration rod 156 and the deceleration plate 157, one end of the second clockwork spring is arranged on the circumferential surface of the deceleration rod 156, and the other end is arranged on the inner wall of the deceleration hole 155. The deceleration rod 156 can be driven to reset by the second clockwork spring. An L-shaped plate 158 is fixedly installed on the right side of the anti-sway plate 153. The anti-sway plate 153 contacts the inner wall of the placement hole. The anti-sway rod 152 can only move and reset slowly so that the anti-sway plate 153 slowly resets to release the limit on the radiator body 5. The slow reset of the anti-sway rod 152 can gradually release the restriction on the radiator body 5, thereby avoiding the radiator body 5 from slipping due to an overly fast release action. The second clockwork spring has a large elastic coefficient.

[0029] A No. 2 spring is arranged between the anti-sway plate 153 and the placement frame 151 , and the No. 2 spring can drive the anti-sway plate 153 to reset. The front side of the anti-sway plate 153 is arranged as an inclined surface, and the anti-sway plate 153 contacts the bottom of the limiting plate 10 .

[0030] The protection component includes a connecting plate 161, a fixing plate 162 and a stabilizing rod 163. The connecting plate 161 is slidably installed on the right side of the installation frame 4, the fixing plate 162 is fixedly installed on the right side of the installation frame 4, and the stabilizing rod 163 is fixedly installed on the right side of the installation frame 4. A gear 164 is rotatably installed on the circumferential surface of the stabilizing rod 163, and a rack 165 is slidably installed on the right side of the fixing plate 162. An anti-pull groove 166 is provided on the front side of the rack 165, and a stabilizing groove 167 is provided on the rear side of the connecting plate 161. By moving and tightening the connecting plate 161, loosening or poor contact of the power cord due to vibration, external force and other factors during use can be avoided.

[0031] The connecting plate 161 is in contact with the connecting hole, the gear 164 is meshed with the rack 165, the gear 164 is made of polycarbonate with a high friction coefficient, and the gear 164 made of polycarbonate can increase the friction between the gear 164 and the power cord. A No. 3 spring is arranged between the connecting plate 161 and the mounting frame 4, and the No. 3 spring can drive the connecting plate 161 to reset.

[0032] A power cord is arranged between the connecting plate 161 and the fixing plate 162. The power cord contacts the inner wall of the connecting hole, and the power cord contacts the gear 164. As the pulling force increases, the squeezing force of the rack 165 on the power cord can effectively enhance the tensile strength of the power cord, thereby preventing the cable from being stretched or damaged, thereby extending the service life of the power cord.

[0033] When this embodiment is working, the limit plate 10 moves downward and contacts the anti-sway plate 153 and squeezes the inclined surface of the anti-sway plate 153. The anti-sway plate 153 is squeezed by the limit plate 10 and moves in the direction close to the radiator body 5. The anti-sway plate 153 moves in the direction close to the radiator body 5 to pull the No. 2 spring. The No. 2 spring is pulled by the anti-sway plate 153 and deforms and accumulates force. At the same time, the anti-sway plate 153 moves in the direction close to the radiator body 5 and contacts the anti-sway groove 154 to limit the radiator body 5. When the limit plate 10 moves upward, the limit plate 10 moves upward and breaks away from the contact with the anti-sway plate 153. After the anti-sway plate 153 breaks away from the contact with the limit plate 10, the anti-sway plate 153 moves to the right under the elastic force of the No. 2 spring. The anti-sway plate 153 moves to the right to reset and drives the anti-sway rod 152 to move. The anti-sway rod 152 moves and contacts the deceleration plate 157 and squeezes the deceleration plate 157. The deceleration plate 157 rotates due to the squeezing of the anti-sway rod 152. The rotation of the deceleration plate 157 drives the deceleration rod 156 to rotate. The rotation of the deceleration rod 156 squeezes the clockwork spring 2. The clockwork spring 2 has a large elastic coefficient and can only be deformed slowly when squeezed by the deceleration rod 156. The clockwork spring 2 slowly deforms, causing the deceleration rod 156 and the deceleration plate 157 to rotate slowly. The slow rotation of the deceleration plate 157 causes the anti-sway rod 152 to move and reset slowly. The anti-sway rod 152 can only move and reset slowly, causing the anti-sway plate 153 to reset slowly to release the limit on the radiator body 5.

[0034] The anti-sway plate 153 moves toward the direction close to the radiator body 5, driving the L-shaped plate 158 to move. The L-shaped plate 158 moves to contact with the connecting plate 161 and squeezes the connecting plate 161. The connecting plate 161 is squeezed by the L-shaped plate 158 and moves toward the direction close to the fixed plate 162. The connecting plate 161 moves toward the direction close to the fixed plate 162 to squeeze the No. 3 spring. The No. 3 spring is squeezed by the connecting plate 161 to produce deformation and accumulate force. At the same time, the connecting plate 161 moves toward the direction close to the fixed plate 162 and contacts the power line. The contact point between the power cord and the mounting frame 4 is tightened. If the power cord of the radiator body 5 is pulled by external force, the power cord is pulled to the right by the external force. The power cord moves to the right and contacts and squeezes the gear 164. The gear 164 rotates due to the pulling of the power cord. The gear 164 rotates and squeezes the rack 165. The rack 165 is squeezed by the gear 164 and moves toward the placement frame 151 and tightens the power cord for the second time, thereby preventing the power cord from being damaged due to excessive pulling.
