[0023] See also Figure 1 , Figure 2 and Figure 3 The heat conducting component 3 includes heat conducting fins 31, which are respectively embedded in the left and right sides of the fixing frame 8. A groove 33 is provided on the side of the heat conducting fin 31 away from the fixing frame 8. The heat dissipation fan 32 can be installed by using the groove 33, so that the heat dissipation fan 32 can stably blow air to the surface of the heat conducting fin 31 to dissipate heat. The heat dissipation fan 32 is fixedly installed in the inner cavity of the groove 33;

[0024] See also Figure 3 and Figure 4 The pressing assembly 7 includes a compression spring 71. By using the compression spring 71, a downward force can be applied to the heat-conducting pressure plate 73, so that the bottom of the heat-conducting pressure plate 73 can be closely attached to the top of the driver body 6, thereby achieving a stable pressing effect. The compression spring 71 is fixedly welded to the four corners of the bottom of the fixing frame 8. The bottom of the compression spring 71 is fixedly connected to the heat-conducting pressure plate 73, and the center of the top of the heat-conducting pressure plate 73 is fixedly connected to the heat-conducting plate 72. The top of the heat-conducting plate 72 passes through the fixing frame 8 and is in sliding contact with the connection therewith.

[0025] See also Figure 3 and Figure 5The limit assembly 5 includes a return spring 51. By using the return spring 51, the limit baffle 53 can be rebounded and reset when it is pressed down, which saves the time of manual operation. At the same time, it can apply an upward elastic force to the limit baffle 53 to prevent the limit baffle 53 from shaking randomly under normal conditions. The return spring 51 is fixedly installed at the bottom of the inner cavity of the installation groove 10, and the top of the return spring 51 is fixedly connected to the limit baffle 53;

[0026] See also Figure 5 The top of the middle end of the front side of the limit baffle 53 is fixedly connected with a push-pull plate 52. By using the push-pull plate 52, the limit baffle 53 can be easily moved. The front side of the push-pull plate 52 penetrates the front side of the installation base plate 1 and slides in contact with it. The front side of the installation base plate 1 is provided with a through hole for the push-pull plate 52 to slide.

[0027] See also Figure 4 The top of the limit plate 9 is fixedly connected to the bottom of the fixing frame 8, and a rubber pad 11 is fixedly installed on the front surface of the limit plate 9.

[0028] See also Figure 1 , Figure 2 and Figure 3 The four corners of the top of the mounting base plate 1 are penetrated with mounting holes 4. By using the mounting holes 4, the mounting base plate 1 can be conveniently installed in a specified position, which is convenient for users to operate it. Sliding grooves 2 are opened on the left and right sides of the top of the mounting base plate 1, and sliding blocks are fixedly connected to the left and right sides of the bottom of the driver body 6. The bottom of the sliding block extends to the inner cavity of the sliding groove 2 and slides in contact with its inner wall.

[0029] When in use, the mounting base plate 1 is installed in the desired position through the mounting hole 4, and then the push-pull plate 52 is pressed downward to drive the limit baffle 53 to move downward until the top of the limit baffle 53 is flush with the top of the mounting base plate 1, at this time, the return spring 51 is in a compressed state, and then the driver body 6 is placed on the top of the mounting base plate 1, so that the sliding block at the bottom thereof slides into the inner cavity of the sliding groove 2. In the process of the driver body 6 sliding backward, the two sides of the driver body 6 are respectively in contact with the heat-conducting fins 31, and the top of the driver body 6 is in contact with the bottom of the heat-conducting pressure plate 73, and pressure is applied to the heat-conducting pressure plate 73 by the compression spring 71, so that the bottom of the heat-conducting pressure plate 73 is tightly attached to the driver body 6, and the heat-conducting plate 72 conducts the heat from the top of the heat-conducting pressure plate 73 to achieve efficient heat dissipation effect, until the rear side of the driver body 6 is in close contact with the front side of the rubber pad 11, at this time, the push-pull plate 52 is released, the return spring 51 is reset, and the limit baffle 53 is bounced up, thereby shielding the front side of the driver body 6 to achieve the installation effect.
