[0026] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0027] Reference Figures 1 to 6The utility model proposes a circuit board clamping device, including a mounting handle 1, a clamping device 2 and a control device 3. One end of the mounting handle 1 is connected to a first bite member 11, and a connecting plate 12 is arranged on the mounting handle 1; the clamping device 2 includes a support block 21 and an abutment block 22, the support block 21 is fixed to the mounting handle 1, the abutment block 22 is rotatably connected to the connecting plate 12 and abuts against a part of the support block 21, a first spring 23 is arranged between the abutment block 22 and the non-abutting part of the support block 21, one end of the abutment block 22 is connected to a second bite member 24, and the second spring 23 is arranged between the abutment block 22 and the non-abutting part of the support block 21. The two engaging members 24 are partially abutted against the first engaging member 11; the control device 3 includes a movable handle 31 and a limit block 32, one end of the movable handle 31 has two connecting ports 33, one connecting port 33 is rotatably connected to the abutting block 22, one end of the limit block 32 is rotatably connected to the other connecting port 33 of the movable handle 31, and the other end is rotatably connected to the support block 21. Rotating the movable handle 31 can make the limit block 32 enter between the abutting parts of the support block 21 and the abutting block 22, so that the abutting block 22 compresses the first spring 23 to make the first and second engaging members partially abut.

[0028] It can be understood that the mounting handle 1 can be used to connect with external equipment. For example, the mounting handles 1 of multiple circuit board clamping devices can be connected to a rod, on which a row of circuit boards can be clamped for electroplating. The mounting handle 1 is also provided with a connecting plate 12 for connecting with other components; the clamping device 2 is a device for providing a bite force, including a support block 21 and an abutment block 22. The support block 21 is connected to the handle rod of the mounting handle 1, and the abutment block 22 is connected to the connecting plate 12, and the abutment block 22 can rotate around the connecting plate 12. The upper parts of the abutment block 22 and the support block 21 can be abutted together, and there is a gap between the lower parts of the two. A first spring 23 is provided in the gap, and the two ends of the first spring 23 respectively abut the support block 21 and the abutment block 22, so as to provide a thrust to abut. The lower half of the block 22 rotates outward around the connecting plate 12, so that the upper half of the abutting block 22 rotates inward around the connecting plate 12 to abut against the supporting block 21. There are two engaging parts, one connected to the mounting handle 1 and the other connected to the abutting block 22. The two can engage with each other, and the circuit board is clamped in the engaging part of the two; the control device 3 includes a movable handle 31 and a limit block 32, one end of the movable handle 31 is connected to the limit block 32 and the abutting block 22 at the same time, and the movable handle 31 can rotate around the abutting block 22, and the limit block 32 can also rotate around the movable handle 31. The limit block 32 is also connected to the supporting block 21 and the connecting part can also rotate freely. Through the above arrangement, the limit block 32 can enter or leave the abutting part between the supporting block 21 and the abutting block 22 by rotating the movable handle 31.

[0029] When the limit block 32 does not enter between the abutting part of the supporting block 21 and the abutting block 22, the first spring 23 pushes the lower half of the abutting block 22 outward around the connecting plate 12, so that the upper half of the abutting block 22 moves inward around the connecting plate 12 and abuts against the supporting block 21, and the two bite parts are loosened at this time; when the movable handle 31 is rotated to make the limit block 32 enter between the abutting part of the supporting block 21 and the abutting block 22, the upper half of the abutting block 22 is pushed outward around the connecting plate 12 by the limit block 32, and the lower half of the abutting block 22 moves inward around the connecting plate 12 and compresses the first spring 23, and the two bite parts bite each other to clamp the circuit board.

[0030] Reference Figures 1 to 4 In one embodiment of the present application, one end of the support block 21 is connected to the handle rod of the mounting handle 1, and the other end extends to the connection between the mounting handle 1 and the first engaging member 11 and is attached to the mounting handle 1. The support block 21 has a bending portion 25, and the limit block 32 is rotatably connected to the bending portion 25.

[0031] It can be understood that one end of the support block 21 is connected to the handle rod of the mounting handle 1, and the other end extends to the end of the mounting handle 1 and fits with the mounting handle 1. The first spring 23 is located at this end of the support block 21. The support block 21 has a bending portion 25, so that the entire support block 21 forms a shape similar to the number "7". The bending portion 25 is the part that abuts against the abutment block 22. At the same time, the limit block 32 is also connected to the bending portion 25, which facilitates the rotation of the movable handle 31 to rotate the limit block 32 to between the parts where the bending portion 25 and the abutment block 22 abut against each other.

[0032] Reference Figures 1 to 4 In one embodiment of the present application, the abutment block 22 includes a mounting arm 26 and an abutment arm 27, the mounting arm 26 is rotatably connected to the connecting plate 12, the second bite member 24 is connected to one end of the mounting wall, and the first spring 23 is arranged between the mounting arm 26 and the support block 21; the abutment arm 27 is connected to the mounting arm 26, and an angle is formed between the two, the abutment arm 27 abuts against the bending portion 25, and the movable handle 31 is rotatably connected to the abutment arm 27.

[0033] It can be understood that the mounting arm 26 and the abutment arm 27 form an angle, so that the abutment block 22 forms a bent structure at the connection position between the two. The mounting arm 26 is located at the bottom, and is used to connect with the connecting plate 12 on the mounting handle 1, and the mounting arm 26 can rotate around the connecting plate 12. The first spring 23 abuts on the mounting arm 26, and the bite piece is also connected to the mounting arm 26; the abutment arm 27 is the part that abuts against the bending portion 25. When the first spring 23 pushes the mounting arm 26 outward around the connecting plate 12, the abutment arm 27 will move inward around the connecting plate 12 and abut against the bending portion 25. The movable handle 31 is also rotatably connected to the abutment arm 27. By rotating the movable handle 31, the limit block 32 can be rotated to between the bending portion 25 and the abutment arm 27.

[0034] Reference Figures 1 to 4 In one embodiment of the present application, the mounting handle 1 is provided with a spring rod 13 , which passes through the support block 21 and extends outward, and a stopper 16 is provided at the free end of the spring rod 13 , and a second spring 17 is provided between the stopper 16 and the support block 21 .

[0035] It can be understood that the spring rod 13 is arranged at the connection part between the mounting handle 1 and the support block 21 and passes through the support block 21, so that the support block 21 is fixed on the mounting handle 1 so that it will not slide up and down along the mounting handle 1. At the same time, the support block 21 can move to a certain extent along the spring rod 13. A stopper 16 is provided at the end of the spring rod 13. A second spring 17 is also sleeved on the spring rod 13. One end of the second spring 17 abuts on the stopper 16, and the other end abuts on the support block 21. The second spring 17 can provide a thrust to make the support block 21 close to the mounting handle 1. When the movable handle 31 is rotated to make the limit When the positioning block 32 rotates to between the bending portion 25 and the abutment arm 27, the support block 21 will move a small distance along the spring rod 13, compressing the second spring 17. The thrust of the second spring 17 on the support block 21 increases, thereby increasing the thrust of the support block 21 on the limit block 32. At this time, since the first spring 23 is also compressed, the force pushing the installation arm 26 will increase, and the force of the abutment arm 27 pushing the limit block 32 will also increase. In this way, the two ends of the limit block 32 are pushed in opposite directions, which can make the limit block 32 more firmly located between the bending portion 25 and the abutment arm 27 and not easy to slip out.

[0036] Reference Figures 1 to 6 In one embodiment of the present application, the circuit board clamping device also includes a clamping plate 4, two through holes 41 are formed at both ends of the clamping plate 4, two screw holes 14 are formed on the mounting handle 1 corresponding to the two through holes 41, a locking rod 18 is inserted between the screw hole 14 and the through hole 41, and a through hole 41 has a notch 42, so that the clamping plate 4 can be rotated to allow the locking rod 18 to enter / escape from the through hole 41 through the notch 42.

[0037] It can be understood that through the above-mentioned arrangement, the clamping plate 4 and the mounting handle 1 can be conveniently fixed to the external device. For example, when the mounting handle 1 is to be fixed to a rod, the rod can be clamped between the mounting handle 1 and the clamping plate 4 through the clamping plate 4. In this example, a screw is selected as the locking rod 18, and the adjusting screw can control the distance between the clamping plate 4 and the mounting handle 1, so as to facilitate the adjustment of the tightness of the installation. A through hole 41 of the clamping plate 4 has a notch 42, and the screw can enter / escape from the through hole 41 through the notch 42. When the mounting handle 1 needs to be removed, the clamping plate 4 only needs to be rotated to make the screw escape from the through hole 41, and the mounting handle 1 can be removed from the external device without removing the screw, which is more convenient.

[0038] Reference Figure 5 In one embodiment of the present application, a serrated engagement opening 15 is provided at the abutting portion of the first and second engagement members.

[0039] It can be understood that the serrated bite 15 has the following advantages: increased grip, the serrated design can improve the grip of the bite piece, and the serrated shape can better bite the surface of the circuit board to prevent the circuit board from slipping; suitable for irregular surfaces, if the surface of the circuit board is uneven or irregular, the serrated bite 15 can better adapt to the shape of the surface and ensure closer contact; improved stability, the design of the serrated bite 15 can reduce the contact area between the bite 15 and the circuit board, increase the pressure, and help improve the stability of the clamping device.

[0040] The technical solution of the utility model is to set a clamping device 2 including a supporting block 21 and an abutting block 22 in a circuit board clamping device, a spring is set between the supporting block 21 and the abutting block 22 so that the two can abut against each other, and then a movable handle 31 connected to the abutting block 22 is set, and a limit block 32 is also provided on the movable handle 31. By rotating the movable handle 31, the limit block 32 is allowed to enter between the abutting parts of the supporting block 21 and the abutting block 22, so that the abutting block 22 compresses the spring to make the bite parts bite each other, so that the circuit board can be clamped or removed more conveniently, and the clamping of the circuit board is more stable without the risk of loosening.
