[0022] The end 1, the end 1 is divided into two, namely the fixed end 10 and the movable end 100 respectively. The clamping surface is between the two ends 1. One side of the movable end 100 away from the fixed end 10 is connected with a support rod 3. The outside of the support rod 3 is slidably connected with a power box 4. The lower parts of the fixed end 10 and the power box 4 are both connected with locking wheels 2. Through the cooperation of the drive inside the power box 4 and the support rod 3, the support rod 3 can be driven to displace inside the power box 4, so that the support rod 3 can push the movable end 100 to move, and the wood between the two ends 1 can be clamped.

[0023] The upper part of the power box 4 is rotatably connected with a driving handle 5. The inside of the power box 4 is limited and obliquely slidably connected with a driving push member 6. The driving handle 5 is drivingly connected with the driving push member 6. Through the rotation of the driving handle 5, the driving push member 6 will slide obliquely inside the power box 4. At the same time, because the driving push member 6 slides obliquely and the support rod 3 is attached to the inside of the driving push member 6, the driving push member 6 will push the support rod 3 to move, so as to complete the clamping action between the two ends 1.

[0024] A limit seat 11 is provided at the position where the fixed end 1 is connected to the locking wheel 2. A threaded sleeve 21 is provided at the position where the locking wheel 2 is connected to the end 1.

[0025] One end of the inner side of the support rod 3 is connected with a blocking block 31, which can prevent the power box 4 from being pushed outwards during use.

[0026] The inner side of the power box 4 includes a cover shell 41 and a transmission seat 42, which drives the pushing member 6 to slide and displace inside the transmission seat 42. And symmetrically and obliquely installed inclined sliding rings 43 are arranged inside the transmission seat 42. By driving the installation of the sliding rods 62 connected to both sides of the pushing member 6 and the inclined sliding rings 43, when the pushing member 6 is displaced, it can be in an oblique sliding state, so as to ensure that there is enough friction between the pushing member 6 and the support rod 3, so as to complete the displacement of the support rod 3.

[0027] Usage process:

[0028] Rotate the lock wheel 2 of the device, remove the fixed end 10 and the lock wheel 2 below the power box 4, and then place both the fixed end 10 and the power box 4 on the table. Let the limiting seats 11 on the bottom surfaces of the fixed end 10 and the power box 4 be inserted into the holes on the table. Then, rotate and connect the lock wheel 2 inside the limiting seats 11 below the fixed end 10 and the power box 4 under the table, and the fixed installation can be completed.

[0029] At this time, insert the support rod 3 into the inner side of the power box 4. The movable end 100 connected to the support rod 3 will form a fixture with the fixed end 10. Place the wood between them, push the support rod 3 to make the two ends 1 abut against the wood, and rotate the driving handle 5 to complete the fixation of the wood. The operation is simple, the installation is fast, and the clamping strength is high and it is convenient to use.
