Since the first elastic telescopic component and the second elastic telescopic component are arranged in groups and horizontally distributed, the present application can adapt to the contour of both irregular circuit boards and common rectangular circuit boards without the need for customized or adjusted clamps. Moreover, the clamping force can be dispersed by the present application to avoid damage to the circuit board and ensure clamping stability. The more first elastic telescopic components and the more second elastic telescopic components in a group, the better the effect.
[0018] Example 2 The difference between this embodiment and Embodiment 1 is that, as Figure 1 , Figure 2 and Figure 3 As shown, the propulsion mechanism includes: Telescopic motor 1; Telescopic motor 1 is fixedly mounted on mounting plate 2; Push plate 3; Push plate 3 and baffle 5 are arranged parallel to each other. The first side of push plate 3 is perpendicularly fixed to the end face of the push rod of telescopic motor 1. The first elastic telescopic component is arranged on the second side of push plate 3.
[0019] Example 3 The difference between this embodiment and Embodiment 2 is that, as Figure 1 and Figure 3As shown, the mounting plate 2 is also provided with two parallel concave slide rails 4 that are perpendicular to the push plate 3. Both ends of the push plate 3 are provided with rectangular notches at the bottom. One concave slide rail 4 is set in one rectangular notch. Each rectangular notch is provided with a rolling mechanism on its top surface. The mounting plate 2 is slidably mounted on the two concave slide rails 4 through the rolling mechanism. One end of the concave slide rail 4 is fixedly connected to the first side of the baffle 5. The first elastic telescopic component and the second elastic telescopic component are both set between the two concave slide rails 4.
[0020] In this embodiment, the concave slide rail 4 can reduce the longitudinal load on the telescopic motor 1 and extend its service life.
[0021] Example 4 The difference between this embodiment and embodiment 3 is that, as Figure 3 As shown, a rolling mechanism includes: U-shaped mounting base 9; The U-shaped mounting base 9 is fixedly mounted on the top surface of a rectangular notch with its opening facing downwards; Mounting shaft 10; both ends of mounting shaft 10 are fixedly connected to the two inner side walls of U-shaped mounting base 9 respectively; Bearing 11; The inner ring of bearing 11 is fixedly mounted on the mounting shaft 10, and the outer ring of bearing 11 is in rolling contact with the inner bottom surface of the concave slide rail 4.
[0022] Example 5 The difference between this embodiment and Embodiment 2 is that, as Figure 1 , Figure 2 and Figure 3 As shown, a first elastic telescopic component includes: First mounting blind hole; The first mounting blind hole is provided on the second side of push plate 3; A first compression spring 8; the first end of the first compression spring 8 is fixedly connected to the bottom of the first mounting blind hole; First push block 7; the first end of the first push block 7 is disposed in the first mounting blind hole and fixedly connected to the second end of the first compression spring 8, and the second end of the first push block 7 is disposed outside the first mounting blind hole.

The second ends of a first push block 7 and a second push block 6 are arranged opposite each other, and the bottom surfaces of all first push blocks 7 and second push blocks 6 are on the same horizontal plane.
[0024] In this embodiment, when the first push block 7 or the second push block 6 makes pressure contact with one side of the circuit board, the first compression spring 8 or the second compression spring can be compressed accordingly to avoid the first push block 7 making hard contact with the circuit board and causing damage to the circuit board. At the same time, the group of the first push block 7 and the second push block 6 can ensure that every part on both sides of the circuit board is subjected to pressure contact force. This design solves the pain points of traditional fixtures being "difficult to adapt and easy to damage", and can also reduce costs and improve efficiency through improved versatility.

The inclined surfaces ensure that the resultant force of the circuit board during compression is directed downwards, preventing it from bouncing back up.
