DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

A first slide groove 5 and a second slide groove 6 are provided on the fixed platform 1. The plurality of clamping blocks 2, the first slide groove 5 and the second slide groove 6 are rectangular when viewed from above. The fixed platform 1 is also provided with a plurality of first mounting grooves 8 which are perpendicular to the first slide groove 5, and the plurality of first mounting grooves 8 have different lengths. The fixed platform 1 is also provided with a plurality of second mounting grooves 9 which are perpendicular to the second slide groove 6, and the plurality of second mounting grooves 9 have different lengths. Sliding plates 7 are provided in the first slide groove 5 and the second slide groove 6, and a receiving groove 12 is provided on the end side of the sliding plate 7. A first elastic member 4 is fixedly installed in the receiving groove 12 by bolts, and a clamping block 3 is fixedly connected to the end of the first elastic member 4 away from the receiving groove 12.

[0019] The two sides of the PCB board that are perpendicular to each other are fixed by the clamping block 2, and then the PCB board is clamped by two clamping blocks 3. When the sizes of the PCB boards are different, the first elastic member 4 is squeezed by sliding the clamping block 3, so that the first elastic member 4 and the clamping block 3 are stored in the first slide groove 5 or the second slide groove 6, and the clamping block 3 and the sliding plate 7 are pushed so that the clamping block 3 is in the first installation groove 8 or the second installation groove 9 corresponding to the PCB, and the clamping block 3 is released. Under the action of the first elastic member 4, the clamping block 3 fixes the PCB board on the fixed platform 1.

[0020] refer to Figure 2 and Figure 3 As shown: the end side of the clamping block 2 is provided with an inclined surface 10 for fixing the PCB board, the clamping block 3 is provided with a clamping groove 14 for clamping the PCB board, the clamping groove 14 is provided with an inclined clamping surface, the clamping block 3 is provided with a threaded hole perpendicular to the fixed platform 1, and a screw 11 is spirally connected in the threaded hole.

[0021] When fixing the PCB board, the inclined surface 10 of the clamping block 2 and the clamping groove 14 on the clamping block 3 press the PCB board onto the end surface of the fixed platform 1, so that the PCB board fits with the fixed platform 1. After the PCB board is fixed, the screw 11 is rotated so that the screw 11 contacts the installation groove, thereby fixing the clamping block 3 to prevent the PCB board from sliding.

[0024] Working principle:

[0025] The two sides of the PCB board are fixed perpendicular to each other by the clamping block 2, and then the PCB board is clamped by two clamping blocks 3. When the sizes of the PCB boards are different, the first elastic member 4 is squeezed by the sliding clamping block 3, and the second elastic member 18 is squeezed by the sliding clamping block 3 through the limiting rod 16, so that the sliding block, the limiting rod 16 and the sliding plate 7 are completely contracted together, and the clamping block 3 and the sliding plate 7 are pushed to slide in the first and second sliding grooves 6, so that the clamping block 3 is in the first and second installation grooves 9 corresponding to the PCB, and the clamping block 3 is released. The clamping block 3 fixes the PCB board under the action of the first elastic member 4 On the fixed table 1, when the clamping block 3 is away from the first slide groove 5 or the second slide groove 6, the limiting rod 16 is pushed to slide to the first mounting groove 8 or the second mounting groove 9 under the elastic force of the second elastic member 18, so that the limiting block 17 on the limiting rod 16 corresponds to the first and second mounting grooves 9, thereby limiting the sliding plate 7 and preventing the sliding plate 7 from sliding along the first and second slide grooves 6. After the PCB board is fixed, the screw 11 is rotated so that the screw 11 contacts the mounting groove, thereby fixing the clamping block 3 and preventing the PCB board from sliding, thereby making the device suitable for PCB boards of different sizes.
