A slider 5 is slidably sleeved on the guide rod 4. Symmetrically arranged connecting plates 7 are installed on the slider 5. The limiting plate 8 is arranged between the two connecting plates 7. The guide rod 4 guides the slider 5, enabling the slider 5 to stably pull the connecting plate 7 when moving.

[0023] An expansion rod 6 connected to the slider 5 is fixedly installed in the support 2. The two guide rods 4 are horizontally arranged correspondingly. A positioning bolt corresponding to the connecting plate 7 is threadedly connected to the slider 5. The limiting plate 8 and the connecting plate 7 extend to the outside of the support 2. The limiting plate 8 is an arc-shaped or U-shaped structure adapted to the wood component. The expansion rod 6 drives the slider 5 to slide on the guide rod 4. The slider 5 drives the connecting plate 7 and the limiting plate 8 to move, and the two limiting plates 8 limit the wood component from both sides.

[0024] Two motors 3 are fixedly installed on the sleeve 1. The output end of the motor 3 is fixedly connected to a bidirectional lead screw 9. Two matching nuts 10 are slidably sleeved on the bidirectional lead screw 9. A clamping seat 11 is arranged in the sleeve 1. A connecting rod 12 is connected between the clamping seat 11 and the nut 10. The bidirectional lead screw 9 is horizontally arranged on both sides of the sleeve 1.

[0025] A guiding long hole for guiding the connecting rod 12 is opened on the sleeve 1. The guiding long hole guides the connecting rod 12 and also limits the moving direction of the nut 10. The two ends of the connecting rod 12 are pin-connected to the clamping seat 11 and the nut 10 respectively. A support rod 13 is placed in the clamping seat 11. An arc-shaped or mouth-shaped structure adapted to the wood component, a clamping plate 14 for limiting the wood component, is integrally connected to the support rod 13. The clamping plate 14 and the support rod 13 extend to the outside of the clamping seat 11. A fixing bolt corresponding to the support rod 13 is threadedly connected to the clamping seat 11.

[0026] By selecting the specifications of the limiting plate 8 and the clamping plate 14, the limiting plate 8 and the clamping plate 14 can clamp and limit the cylindrical or cuboid wood components after selection, not only ensuring the stability of the wood component in the sleeve 1, but also enabling the sleeve 1 to protect wood components of different specifications, so as to realize anti-cracking protection for the wood components.

[0027] It should be noted that the specific model specifications of the telescopic rod 6 and the motor 3 need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0028] The functional principle of the present utility model can be described through the following operation modes:
