Spring five is sleeved on the outer surface of the telescopic rod, connected to the lower surface of the connecting plate at the top, and connected to the upper surface of the spring base four at the bottom. Its main technical effects are: it realizes the cutting of fixed-size samples of fiber reinforced composite preforms, improves the repetition rate of the sample size, and the entire process is mechanically controlled to avoid the influence of human factors. When the load is applied, a certain pressure is transmitted to the surface of the fabric sample through the spring, which reduces the deformation of the sample caused by the complex cutting process, and greatly improves the efficiency, repeatability and accuracy of the later tests.

A pasting tool for a fiber-reinforced material tensile spline reinforcement sheet, comprising a supporting block 1, and also comprising a first connecting rod 2, a second connecting rod 3, a first limit block 4 and a second limit block 5. The number of the supporting blocks 1 is several and there are two groups. A first through hole 11 is opened on the outer wall of one side of the supporting block 1, and a second through hole 12 is opened on the outer wall of the adjacent side of the supporting block 1. The number of the first connecting rods 2 is two, and the two first connecting rods 2 are respectively connected to the first through holes 11 of two of the supporting blocks 1. The number of the second connecting rods 3 is two, and the two second connecting rods 3 are respectively connected to the two groups of supporting blocks 1. The first limit block 4 is threadedly connected to both ends of the first connecting rod 2, and the second limit block 5 is threadedly connected to both ends of the second connecting rod 3.

[0024] Specifically, Figure 1 and Figure 4 As shown, there are several supporting blocks 1, and the several supporting blocks 1 are divided into two groups. The number of the first connecting rods 2 and the second connecting rods 3 are both two, one of the first connecting rods 2 is connected to the first through hole 11 of one group of supporting blocks 1, and the other first connecting rod 2 is connected to the first through hole 11 of the other group of supporting blocks 1, and the two second connecting rods 3 are respectively connected to the second through holes 12 of the two groups of supporting blocks 1, so that the first connecting rods 2, the two groups of supporting blocks 1, and the second connecting rods 3 form a rectangular structure, and the width of different specimens can be adapted by adjusting the number of one group of supporting blocks 1, and the length of different specimens can be adapted by adjusting the spacing between the two groups of supporting blocks 1. The first limit blocks 4 are threadedly connected to both ends of the first connecting rod 2, and the first limit blocks 4 are connected to the first connecting rod 2. To limit the position of the supporting block 1 on the first connecting rod 2 and prevent the supporting block 1 from moving on the first connecting rod 2, a first through hole 11 is opened on the outer wall on one side of the supporting block 1, and the first connecting rod 2 is connected to the inside of the first through hole 11, and a second through hole 12 is opened on the outer wall on the adjacent side of the supporting block 1, and the second connecting rod 3 is connected to the second through hole 12. Preferably, the first through hole 11 and the second through hole 12 are staggered and vertically arranged to ensure that the first connecting rod 2 and the second connecting rod 3 can both be connected to the supporting block 1, and second limit blocks 5 are threadedly connected at both ends of the second connecting rod 3. The second limit blocks 5 can limit the movement of the supporting block 1 connected to the second connecting rod 3, and by adjusting the spacing between the two groups of supporting blocks 1, samples of different lengths can be adapted and made.

[0025] In the utility model, two groups of supporting blocks 1 are connected by a second connecting rod 3 and a second limiting block 5. The spacing between the two groups of supporting blocks 1 can be adjusted by the second limiting block 5, so as to adapt to the lengths of different samples. Each group of supporting blocks 1 is connected by a first connecting rod 2 and a first limiting block 4, so as to adapt to the widths of different samples.
