A circuit board is composed of an integrated circuit, a quartz resonator, a fine-tuning capacitor and a printed circuit board. During the production process of the circuit board, a large number of positioning holes and other holes need to be drilled on the board. During the drilling process, it is generally necessary to set a pad under the circuit board to support the circuit board and avoid deformation of the circuit board and affect the drilling accuracy.

When used for a long time, the positioning holes into which the positioning pins are inserted are easily worn, thereby affecting the positioning accuracy, so that the pads need to be replaced frequently. The existing pads are mostly integrated designs, which require overall replacement, resulting in increased costs and poor practicality. To this end, we provide a pad for drilling circuit boards to solve this problem. Utility Model Content

[0023] The lower end of the base plate 1 is symmetrically connected to the side plates 3, and a fixing mechanism 4 is installed between the side plates 3. The fixing mechanism 4 includes a mounting plate 41, an electric push rod 42, a connecting plate 43, a first tooth plate 44, a connecting shaft 45, a gear 46, a second tooth plate 47 and a clamping plate 48. The mounting plate 41 is installed on the outside of the two side plates 3, and the electric push rod 42 is installed on the outside of the mounting plate 41. The output end of the electric push rod 42 passes through the mounting plate 41 and is connected to the connecting plate 43. One side of the connecting plate 43 is connected to the first tooth plate 44. The upper end of the first tooth plate 44 meshes with the gear 46. The corresponding side of the side plate 3 is rotated together to connect the connecting shaft. 45, the connecting shaft 45 is sleeved with the gear 46, the upper end of the gear 46 meshes with the second tooth plate 47, the upper ends of the second tooth plate 47 and the first tooth plate 44 are both connected with a clamping plate 48, the outer side of the second tooth plate 47 is symmetrically connected with a slider 49, and the corresponding side between the side plates 3 is provided with a slide groove 5 slidably connected therewith, the clamping plate 48 is an L-shaped plate, the height of the clamping plate 48 at the upper end of the second tooth plate 47 is less than the height of the clamping plate 48 at the upper end of the first tooth plate 44, and the upper end surfaces of the two clamping plates 48 are located on the same horizontal line, and the output of the electric push rod 42 pushes the connecting plate 43 and the first tooth plate 44 on one side thereof to move left and right, Thus, the first toothed plate 44 drives the gear 46 and the connecting shaft 45 of its inner cavity to rotate, and the gear 46 drives the second toothed plate 47 meshed at its upper end to move left and right, and the second toothed plate 47 stably slides in the slide groove 5 on the outer side of the side plate 3 through the slider 49, which effectively improves the movement stability, and the first toothed plate 44 and the second toothed plate 47 move synchronously in the same or opposite directions, and then when the entire pad mechanism 2 is installed on the inner side of the base plate 1, the first toothed plate 44 and the second toothed plate 47 move in the same direction, and then the first toothed plate 44 and the second toothed plate 47 both drive the L-shaped plate-shaped clamping plate 4 8 moves toward the auxiliary pad 22 and clamps the two auxiliary pads 22, thereby effectively clamping and fixing the pad mechanism 2, and the height horizontal lines of the clamping plates 48 are the same, which effectively improves the aesthetics and clamping stability.

[0024] Working principle: through the first clamping block 25 on one side of an auxiliary pad 22 and the second clamping slot 27 on the outer side of a main pad 21, and the first clamping slot 24 on one side of another auxiliary pad 22 is clamped with the second clamping block 26 on the outer side of another main pad 21, and several main pads 21 are mutually clamped through the second clamping slots 27 and second clamping blocks 26 on both sides, which is convenient for effective assembly to form an integral pad mechanism 2, and convenient for supporting when drilling holes in the circuit board, and the main pad 21 is slidably connected to the limiting groove 6 on the inner side of the base plate 1 through the limiting block 28, which effectively limits the main pad 21, and effectively increases the stability of the pad mechanism 2. When the pad mechanism 2 is installed, the connecting plate 43 and the first tooth plate 44 on one side thereof are moved by the output of the electric push rod 42. Thus, the first tooth plate 44 drives the gear 46 to rotate, and the gear 46 drives the second tooth plate 47 meshing at its upper end to move, and the first tooth plate 44 and the second tooth plate 47 move in the same direction, and then the first tooth plate 44 and the second tooth plate 47 both drive the L-shaped plate-shaped clamping plate 48 to move toward the auxiliary pad 22, and clamp the two auxiliary pads 22, thereby effectively clamping and fixing the pad mechanism 2. When the positioning hole 23 at the upper end of the auxiliary pad 22 is worn after long-term use or the main pad 21 needs to be replaced, the first tooth plate 44 and the second tooth plate 47 move in opposite directions, and then the clamping plate 48 moves away from the auxiliary pad 22, thereby facilitating the disassembly and replacement of the auxiliary pad 22 and the main pad 21, which is convenient for use, effectively reduces costs, and improves the use effect and practicality.
