The two ends of the double-headed screw rod 31 pass through the two lower limit plates 21 respectively and are threadedly connected to the two lower limit plates 21.

[0031] When in use, the double-headed screw 31 is rotated, and the double-headed screw 31 drives the two lower limit plates 21 to slide synchronously in opposite directions until the two lower limit plates 21 are adjusted to a predetermined position. The operation is convenient, the adjustment is precise, and the fixation is stable.

[0032] To facilitate the rotation of the double-ended screw 31, please refer to Figure 1 In a preferred embodiment, a handle 32 is fixedly connected to the upper end of the double-ended screw rod 31 .

[0033] When in use, the handle 32 is held to rotate the double-ended screw 31, thereby reducing the possibility of slipping.

[0034] To adjust the height of the upper limit plate 41, please refer to Figure 1 In a preferred embodiment, the second adjustment component 5 includes a screw rod 51 rotatably connected to the top of the lower limit plate 21, and a screw barrel 52 is fixedly connected to the bottom of the upper limit plate 41. The screw rod 51 and the screw barrel 52 both extend along the height direction of the bottom limit plate 11, and the screw rod 51 is coaxially threaded in the screw barrel 52.

[0035] During use, when adjusting the height of the upper limit plate 41, the screw rod 51 is rotated, and the screw rod 51 drives the screw barrel 52 to rise and fall, and the screw barrel 52 drives the upper limit plate 41 to rise and fall. Not only is the operation convenient, but the screw rod 51 and the screw barrel 52 are both located between the upper limit plate 41 and the lower limit plate 21, and will not hinder the placement of the circuit board.

Thereby, the synchronous adjustment of the distance between the two lower limit plates 21 and the height of the two upper limit plates 41 is realized, and the operation is more convenient.

[0042] In order to make the circuit board easier to enter the limit groove 12, please refer to Figure 2 In a preferred embodiment, the bottom limit plate 11, the upper limit plate 41 and the lower limit plate 21 are all provided with corresponding limit grooves 12 for accommodating the circuit board, and the openings of the limit grooves 12 are provided with guide surfaces 13.

[0043] During use, when the circuit board is placed in the limiting groove 12 , the guide surface 13 plays a guiding role, making it easier for the circuit board to enter the limiting groove 12 , thus saving the time of aligning the circuit board with the limiting groove 12 .

[0044] To reduce the possibility of circuit board damage, please refer to Figure 2In a preferred embodiment, a buffer sleeve 7 is fixedly connected to the limiting groove 12, and the material of the buffer sleeve 7 is rubber.

[0045] During use, when the circuit board is placed in the limiting sleeve, the buffer sleeve 7 plays a buffering role, thereby reducing the possibility of damage to the circuit board.

[0046] In order to facilitate the installation and removal of the buffer sleeve 7, please refer to Figure 2 In a preferred embodiment, a guide strip 71 is provided on the side of the buffer sleeve 7 close to the limiting groove 12, and the guide strip 71 is radially extended from the side close to the buffer sleeve 7 to the side away from the buffer sleeve 7, and a guide groove 72 for accommodating the guide strip 71 is provided on the limiting groove 12.

[0047] When in use, when installing the buffer sleeve 7, align the guide strip 71 on the buffer sleeve 7 with the guide groove and slide it along the guide groove. The guide strip 71 is radial, which reduces the possibility of the guide strip 71 coming out of the guide groove. When removing the buffer sleeve 7, just slide the guide strip 71 out of the guide groove. The disassembly and assembly are convenient, and when the buffer sleeve 7 is aged and deformed, it is convenient to replace the buffer sleeve 7.
