[0030] Refer to Figure 1 , an embodiment of the present utility model provides a woodworking clamp, which includes a fixed rod 1. A screw rod 2 is provided on the fixed rod 1, and a clamping seat 21 is provided at one end of the screw rod 2. A movable seat 3 capable of sliding is provided on the fixed rod 1. The movable seat 3 is fixed on the fixed rod 1 by a locking screw 31. By quickly sliding the movable seat 3, the distance between the movable seat 3 and the clamping seat 21 is adjusted, and then the wooden block is clamped by fine-tuning through the screw rod 2. Compared with adjusting by rotating the screw rod, the sliding adjustment has a faster speed and higher adjustment efficiency.

[0031] Refer to Figure 1 , specifically, the fixed rod 1 is an L-shaped rod, including a long rod and a short rod. The screw rod 2 and the movable seat 3 are respectively arranged on the two rods of the fixed rod 1. The screw rod 2 is arranged on the short rod, and the movable seat 3 is arranged on the long rod, which has a larger adjustment range.

[0032] Refer to Figure 1 、 Figure 4 and Figure 5 , in an alternative embodiment, the screw rod 2 penetrates through the fixed rod 1, and a locking handle 22 is provided at the other end of the screw rod 2, which is convenient for adjusting the rotation of the screw rod 2 by hand-twisting the handle. A smooth section 23 is provided on the screw rod 2. The clamping seat 21 includes a metal seat 211 movably sleeved on the smooth section 23 and a rubber pad 212 provided on the metal seat 211, which protects the board and prevents pits on the board after clamping. The opening of the metal seat 211 is larger than the diameter of the smooth section 23. Only the opening needs to be slightly larger than the diameter of the smooth section 23, and the length of the smooth section 23 is also slightly larger than the length of the opening. When the metal seat 211 is sleeved on the smooth section 23, the metal seat 211 can be finely adjusted in spatial position, not only by the up and down adjustment of the screw rod 2, but also more conducive to fixing on a board with an uneven surface. The metal seat 211 is a hollow seat, and the rubber pad 212 is fixed by glue. When the metal seat 211 is sleeved on the smooth section 23, an iron sheet can be welded at the end of the smooth section 23 to prevent the metal seat 211 from falling off, or a threaded section can be directly provided at the bottom of the smooth section 23, and a nut can be screwed on the threaded section to prevent the metal seat 211 from falling.

[0033] Refer to Figure 1 and Figure 3 In an alternative embodiment, the moving seat 3 is a square seat, preferably a rectangular one. An opening is provided on the moving seat 3 for the fixing rod 1 to pass through, so as to quickly adjust the distance between the moving seat 3 and the clamping seat 21. A fixing hole 32 is provided on the moving seat 3 so that the locking screw 31 can fix the moving seat 3 on the fixing rod 1. As Figure 3 shown, it is a schematic structural diagram of the cooperation between the moving seat 3 and the fixing rod 1 after removing the locking screw 31. After the locking screw 31 is inserted into the fixing hole 32, the moving seat 3 is locked.

[0034] Refer to Figure 3 In an alternative embodiment, a plurality of scale lines 11 are provided on the rod of the fixing rod 1 where the moving seat 3 is provided. A fixing groove 12 is provided below each scale line 11, and the fixing groove 12 cooperates with the locking screw 31 to fix the moving seat 3. Preferably, there are 5 scale lines, which are marked 2, 4, 6, 8, 10 from top to bottom in sequence, and a fixing groove 12 is also provided below each scale line 11. When the locking screw 31 fixes the moving seat 3 through the fixing groove 12, the uppermost part of the moving seat 3 is flush with the scale line 11. The user can select different fixing grooves 12 according to different plates to prevent damage to the fixing rod 1, and the fixing effect is better through the fixing groove. Then, fine adjustment is carried out through the screw rod 2, and the fine adjustment length of the screw rod 2 can be selected according to the actual situation. A schematic structural diagram of the fixed plate is as Figure 2 shown.

[0035] A fixing groove 12 is added to the topmost scale for fixing thinner wood. Embodiment Two

[0036] On the basis of Embodiment One, in order to deal with the clamping of some special-shaped plates or the simultaneous processing (fixing or simultaneous cutting) of two plates, the following improvements are made:

[0037] Refer to Figure 6 In an alternative embodiment, a second L-shaped rod 4 is provided on the rod of the fixing rod 1 where the moving seat 3 is provided. The long rod of the second L-shaped rod 4 is connected to the long rod of the fixing rod 1, and the long rod of the fixing rod 1 serves as the fixing base for the plate. The scale lines 11 and the fixing grooves 12 of the fixing rod 1 can be adjusted according to the actual situation. A second screw rod 5 is provided on the rod of the second L-shaped rod 4 away from the fixing rod 1, and a second clamping seat 6 is provided on the second screw rod 5. The wood is placed between the long rod of the fixing rod 1 and the second clamping seat 6. A schematic structural diagram of the clamped state is as Figure 7 shown.

[0038] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
