2. The gold finger type fan frame according to claim 1 , wherein the first frame body is provided with a first recess corresponding to the board body and a second recess corresponding to the gold finger block, the first recess being in communication with the second recess; the side of the first frame body is provided with a third recess corresponding to the outlet body, the first recess is internally provided with positioning columns in a symmetric manner, and the board body is provided with positioning openings corresponding to the positioning columns; and a recess inner wall of the third recess is provided with a first clamping recess connected to the rear plastic housing in a clamping manner.

3. The gold finger type fan frame according to claim 1 , wherein the connection block comprises a front plastic housing, symmetrically arranged terminals embedded in the front plastic housing, and a connection plate connected to an end, far away from the front plastic housing, of each terminal, the front plastic housing comprising a first housing body, fourth recesses which are symmetrically provided in the first housing body and correspond to sides of the terminals, and a fifth recess which is provided in a side, far away from the terminals, of the first housing body and is located between the fourth recesses, the gold finger block being embedded in the fifth recess correspondingly, and two sides of a surface, close to the terminals, of the first housing body being provided with first clamping blocks.

4. The gold finger type fan frame according to claim 3 , wherein the rear plastic housing comprises a second housing body, second clamping blocks arranged on two sides of the second housing body and connected to the third recess in a clamped manner, and second clamping recesses provided on an inner side of the second housing body and connected to the first clamping blocks in a clamping manner.

5. The gold finger type fan frame according to claim 3 , wherein the side of the terminal is provided with a barbed block.

6. A double-layer connection structure of a gold finger type fan frame, comprising a second frame body detachably assembled to a first frame body, a second circuit board embedded on the second frame body and spaced from a first circuit board by 3.5 mm-6 mm, and an outlet body embedded on a side of the second frame body and detachably connected to the second circuit board, wherein the second circuit board comprises a board body, a gold finger block arranged at a side of the board body and inserted into the outlet body, the outlet body comprises a connection block connected to the gold finger block, a rear plastic housing connected to the connection block, and wires embedded in the rear plastic housing and electrically connected to the connection block, four corners at a lower end of the first frame body are provided with connection clamping recesses in a rectangular array manner, and an upper end of the second frame body are provided with connection clamping blocks corresponding to the connection clamping recesses.

7. The double-layer connection structure of a gold finger type fan frame according to claim 6 , wherein the second frame body is provided with a first recess corresponding to the board body and a second recess corresponding to the gold finger block, the first recess being in communication with the second recess; the side of the second frame body is provided with a third recess corresponding to the outlet body, the first recess is internally provided with positioning columns in a symmetric manner, and the board body is provided with positioning openings corresponding to the positioning columns; and a recess inner wall of the third recess is provided with a first clamping recess connected to the rear plastic housing in a clamping manner.

8. The double-layer connection structure of a gold finger type fan frame according to claim 6 , wherein the connection block comprises front plastic housings, symmetrically arranged terminals embedded in the front plastic housing, and a connection plate connected to an end, far away from the front plastic housing, of each terminal, wherein each front plastic housing comprises a first housing body, fourth recesses which are symmetrically provided in the first housing body and correspond to sides of the terminals, and a fifth recess which is provided in a side, far away from the terminals, of the first housing body and is located between the fourth recesses, the gold finger block being embedded in the fifth recess correspondingly, and two sides of a surface, close to the terminals, of the first housing body being provided with first clamping blocks; the two front plastic housings are arranged symmetrically up and down with respect to the rear plastic housing, and the two connection plates are arranged corresponding to the front plastic housings respectively.

9. The double-layer connection structure of a gold finger type fan frame according to claim 6 , wherein the wires comprise wire A and wire B which are electrically connected to a connection plate, the wire A is vertically arranged, a joint of the wire B and the first connection plate is obliquely arranged, and an end, far away from the joint, of the wire B is arranged parallel to the wire A.
