technical field

The utility model relates to a clamping tool, in particular to an improved quick clamp which can be used for clamping and positioning on a work table for carpentry or other purposes.

Background technique

Because the clamps are generally inserted into the work table to clamp the workpiece for processing, there are many kinds of appearance types, which are too numerous to enumerate. However, the structure is generally adopted as shown in Figure 1 to achieve the possible Tightly positioned in the aperture on the worktable, as shown in Figure 1, an insertion rod 1 is provided on the fixture, and the insertion rod 1 is directly inserted into the preset aperture 3 on the worktable 2 in an inclined manner place, so that the side surface of the plunger 1 can touch the upper and lower sides 31 and 32 of the aperture 3 on the work surface 2, and then cooperate with components such as nuts 33 and gaskets 34 to come from the bottom of the plunger 1 The end screw is fixed to the bottom end surface of the work surface 2. This kind of tight positioning and fixing method has the following shortcomings in use:

First, in use, because the hole 3 where the side surface of the plunger 1 touches the wooden work surface 2 is the junction of the upper and lower points 31, 32, so after tightening with the nut 33, It is easy to sag or break the side end 31 as shown in FIG. 2 . In this way, a gap 35 will be generated, and the plunger 1 will fluctuate during the processing operation, which will affect the processing of the workpiece 8. quality.

Second, in terms of the structural design of the fixture, the insertion rod 1 must be inserted through the preset aperture 3 on the work surface 2, and then tightened by the nut 33 to fix it, so the work in use The table top 2 must be limited to the work table 2 that has the aperture 3 that completely penetrates the bottom. There is another kind of fixture structure as shown in Figure 3, although this fixture is provided with a sleeve 84 that can expand outwards at its bottom end, when inserting in the preset aperture on the work surface, can solve above-listed problem. However, it still has other deficiencies in use, which are explained as follows:

Second, when it is inserted into the preset aperture on the worktable, the knob 83 is completely rotated by hand to expand the sleeve 84 outward, so it is very laborious and inconvenient.

Third, when adjusting the sliding seat 85 up and down in use, as shown in Figure 4, one end of the sliding seat 85 must be lifted and tilted so that the two rod bodies 86, 87 in the sliding seat 85 are in contact with the screw rod 80 to make it Positioning, this mode of use is easy to cause sliding seat 85 to produce sliding seat 85 due to fluctuating during work or accidentally bumping into sliding seat 85, and the function of complete fastening cannot be achieved.

Fourth, when the workpiece is to be clamped in use, the knob 88 must be rotated by hand to make the clamping seat 89 gradually downward, which is very time-consuming and slow in operation.

The 5th, the bottom end of its clamp seat 89 is flat and linear design, when running into the workpiece that profile is arc shape, just is not easy to clamp.
