When the rubber block is worn, it can be easily replaced.

[0016] Preferably, one end of the clamping block is fixedly connected to a pulling block, and the cross section of the pulling block is semicircular.

[0017] The effect achieved by the above components is that by providing the pulling block, the contact area of ​​one end of the card block can be increased, making it easier to manually hold and pull it.

When the U-shaped frame, the first threaded rod 5 and the abutment block 6 are used to clamp the channel steel, the hexagonal hole block 32 on the rubber block 31 is first manually inserted into the slot 33 on the abutment block 6, and then the block 35 is held and inserted from the slot 34 so that it is inserted into the inner wall of the hexagonal hole block 32, so that the rubber block 31 can be fixed on one side of the abutment block 6, increasing the friction force on one side of the abutment block 6, and it is not easy to slide when the abutment block 6 abuts on the channel steel, and the abutment is more stable.
