[0002] The woodworking clamp is an essential tool for woodworking. It has a simple structure and is easy to use, making it a good helper in woodworking.

[0003] The existing common woodworking clamps are positioned by squeezing long screws, have a simple structure and are inexpensive to purchase. However, after long-term use, the fixed feet under the long screws will be deformed or even break and fall off the long screws. The fixed feet are relatively wide to prevent the thinner long screws from crushing the wooden boards. However, after the fixed feet are damaged, the staff needs to place paper sheets or the like under the long screws as a buffer. When installing the woodworking clamps, the staff needs to screw the long screws with one hand and hold the woodworking clamp body with the other hand, so the operation of placing the buffers is more troublesome.

An operating rod 3 is slidably connected at the top end of the long screw rod 2. A No. 1 thread 14 is provided at one end of the operating rod 3. A No. 1 screw sleeve 4 is screwed on the No. 1 thread 14. When disassembling, the No. 2 thread 15 is screwed counterclockwise. The screw sleeve 9 can be used to remove the fixed foot 8, and the fixed foot 8 can be installed by screwing the No. 2 screw sleeve 9 clockwise. By arranging a No. 2 thread 15 under the long screw rod 2 and arranging a No. 2 screw sleeve 9 on the fixed foot 8 to screw with the No. 2 thread 15, the fixed foot 8 on the woodworking clamp can be screwed and disassembled, so that it is convenient to replace the fixed foot 8 when it is damaged, which is convenient for use. In addition, by arranging the buffer sleeve 5, a protective effect is played, which can prevent the user's hands from being injured, thereby improving practicality.

[0023] In this embodiment, if Figure 1 and Figure 2 As shown, the end of the operating rod 3 away from the No. 1 threaded sleeve 4 is sleeved with a buffer sleeve 5, and the buffer sleeve 5 is made of silicone material and has a soft texture to prevent the user from hurting the hand when bending the operating rod 3.
