A U-shaped guard plate 3 is fixed to the top surface of the U-shaped base 1, and a support frame 2 is fixed to the top surface of the U-shaped base 1 corresponding to the U-shaped guard plate 3, and a hydraulic cylinder 4 is fixedly installed in the middle of the top surface of the support frame 2, and two symmetrically distributed limit rods 9 are fixed to one side of the U-shaped guard plate 3, and the outer surfaces of the two limit rods 9 are slidably connected with sliders 13, and a movable plate 6 matching the U-shaped guard plate 3 is fixed to one side of the two sliders 13, and a clamping mechanism is provided on one side of the two sliders 13 corresponding to the U-shaped guard plate 3.

[0022] Further Figure 2 and Figure 4 As shown, it is worth explaining in detail that the positioning mechanism includes two mounting blocks 21 fixed to the surface of the movable seat 5, and a plurality of limiting holes 11 are evenly opened on the surfaces of the two fixed rods 10. The limiting holes 11 corresponding to the top surfaces of the two mounting blocks 21 on one side are plugged with U-shaped plug rods 12, and the U-shaped plug rods 12 all pass through the limiting holes 11, thereby limiting the movable seat 5.

[0023] Further Figure 2 and Figure 3As shown, it is worth explaining in detail that the clamping mechanism includes an elastic connecting rod 14 fixed to the surface of the slider 13, and the side of the elastic connecting rod 14 is fixed with an arc-shaped protrusion 15 that matches the top surface of the U-shaped guard plate 3. When the slider 13 moves to the end of the limiting rod 9 along with the movable plate 6, the arc-shaped protrusion 15 is squeezed and clamped on the top surface of the U-shaped guard plate 3, thereby facilitating the limiting of the movable plate 6.

[0024] This scheme has the following working process: when encountering bamboo boards with quality problems, the bamboo boards may be stressed and cracked, and the broken bamboo board debris is easy to splash, which can easily cause certain injuries to the testers. At the same time, the test range of the test device is relatively limited, which affects the test efficiency. By adjusting the distance between the two movable seats 5 according to the length of the bamboo board, the movable seat 5 is pulled to slide on the two fixed rods 10. After adjustment, the U-shaped plug rod 12 is inserted into the mounting block 21, and the bottom end of the U-shaped plug rod 12 passes through the limiting hole 11, thereby limiting the movable seat 5, and then the two ends of the bamboo board are fixed. Place it in the placement hole 17, rotate the threaded rod 20, so that the pressure plate 18 limits the bamboo board, and then start the hydraulic cylinder 4, so that the telescopic end of the hydraulic cylinder 4 squeezes the bamboo board, and protects it through the U-shaped guard plate 3 and the movable plate 6 to prevent the poor quality bamboo board from cracking and splashing to injure the tester; the movable plate 6 moves up and opens, and the slider 13 slides on the limiting rod 9 with the movable plate 6. After the movable plate 6 is opened, the arc-shaped protrusion 15 on the elastic connecting rod 14 squeezes the top surface of the U-shaped guard plate 3 and is stuck on the U-shaped guard plate 3, thereby limiting the movable plate 6, which makes it convenient for the tester to fix the bamboo board.

The U-shaped guard plate 3 and the movable plate 6 are used for protection to prevent the poor quality bamboo boards from cracking and splashing to injure the testers, thereby improving the safety of the test. The setting of the clamping mechanism facilitates the limiting of the movable plate 6 when it is opened.

[0026] Further Figure 3 and Figure 4 As shown, it is worth explaining in detail that a grip rod 16 is fixed to the side of the elastic connecting rod 14 away from the U-shaped guard plate 3. When the movable plate 6 needs to be closed, the elastic connecting rod 14 is pulled to bend by the grip rod 16, so that the arc-shaped protrusion 15 is separated from the top surface of the U-shaped guard plate 3; two moving rods 19 are fixed to the top surface of the pressure plate 18, and the two moving rods 19 movably penetrate the movable seat 5. When the threaded rod 20 drives the pressure plate 18 to move, the two moving rods 19 limit the pressure plate 18, thereby maintaining the stability of the pressure plate 18 when it is adjusted up and down.

[0027] Further Figure 1 , Figure 2 and Figure 4 As shown, it is worth explaining in detail that an observation window 7 is fixed on one side of the movable plate 6. After the movable plate 6 is closed, the observation window 7 is used to observe the process of the bamboo board test; a grip ring 8 is fixed on the lower end of one side of the movable plate 6, and the grip ring 8 facilitates the movement of the movable plate 6 and improves the convenience of operation for the staff; a rotating block is fixed on the top of the threaded rod 20, and the rotating block facilitates the rotation of the threaded rod 20.

[0028] The hydraulic cylinder 4 can be purchased on the market. The hydraulic cylinder 4 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
