As shown in Fig. 1, the clamp tool of the present invention comprises a stationary support member 2 having a stationary jaw 1, a movable support member 4 having a movable jaw 3, a slide bar 5, and a movable handle 6 Wherein the sliding bar 5 is threaded into and attached to the stationary support 2 and the actuation plate 8 equipped with a traction plate 8 for adjusting the sliding bar 5, the movable support 4 Mounted in one end of the slide bar 5, and the stationary jaw 1 and the movable jaw 3 are oriented opposite each other. The stationary support 2 comprises a stationary shank 9 extending towards the end opposite the stationary jaw 1 and a pivot point 10 for engagement, the actuation shank 6 and the stationary shank 9 being oriented opposite one another, The actuating handle 6 includes an actuating point 11 for pushing the actuating plates 8, a first supporting point 12 is away from the actuating point 11 and a second supporting point 13 is adjacent to the actuating point 11, the A support point 12 is coupled to the stationary support 2 by a spring element 14, the second support point 13 and the pivot point 10 for engagement being oriented opposite each other.

In order to minimize damage to the surface of a workpiece, the stationary clip 1 and the touch points of the movable jaw 3 having the fastened workpiece can be made of an elastic material such as rubber. In order to ensure strength and rigidity, the slide bar 5 may be provided by a metal material, and the stationary support member 2, the movable support member 4, and the actuating handle 6 may be made of plastic.

The clamp tool can have different functions depending on the different distances from the first support point 12 or the second support point 13 to the actuation point 11.

As shown in Fig. 2, there is no workpiece clamped by the stationary support 2 and the movable support 4 in the unloading mode. When the stationary shank 9 is fastened with the actuating shank 6, the actuating shank 6 moves about the axis of the first support point 12, while the second support point 13 is dismantled from the pivot point 10 for engagement under the effect of the spring element 14. from. The actuating lever 6 is used as a lever. Since the first supporting point 12 is relatively far from the actuating point 11, the force applying arm L1 (i.e., the fastening point and the first supporting point 12) when the actuating handle is fastened is The ratio between the distance) and the resistance arm L2 (i.e., the distance between the actuation point 11 and the first support point 12) is relatively small. The actuation plate 8 displaces the slide bar 5 to the right over a relatively large distance D1 each time the actuation handle 6 is fastened. Actuating point 11 acquires a relatively weak pushing force that causes the sliding bar actuated by the actuating plate to advance rapidly to the right. Fastening in the unloading mode is less laborious and is especially useful for operators who cannot assist with another hand.

As shown in FIG. 3, the stationary support 2 and the movable support 4 are held and are intended to further clamp the workpiece 35. When the stationary shank 9 and the actuating shank 6 are fastened, the spring element 14 is deformed under the pressure of the fastening force. The pivot point for engagement is engaged by the second support point 13 and the actuation handle 6 is moved about the axis of the second support point 13. Similarly, with the actuating lever 6 as a lever, since the second supporting point 13 is relatively close to the actuating point 11, the force applying arm L3 (ie, the clasping point and the first when the actuating lever 6 is fastened) The ratio of the distance between the two support points 13 to the resistance arm L4 (i.e., the distance between the actuation point 11 and the second support point 13) is relatively large. Whenever the actuation handle 6 is fastened, the actuation plate 8 displaces the slide bar 5 to the right over a relatively small distance D2 (D2 < D1). The actuation point 11 acquires a relatively strong urging force that causes the slide bar 5 actuated by the actuation plate 8 to slowly advance to the right.

In fact, the operating conditions of the first support point 12 and the second support point 13 are automatically offset during the process of holding the stationary support 2 and the movable support 4 and intending to further clamp the workpiece 35.

In order to further improve and assist the above-described technical embodiments, the present invention also includes the following additional technical features that can be selectively applied depending on the desired function: the spring element 14 that connects the first support point 12 to the stationary support 2 is a A torsion spring is mounted in the stationary support 2 by a pivot point 15 and the two ends of the torsion spring are attached to the first support point 12 and the stationary support 2, respectively. In this configuration, the torsion spring is mounted in the stationary jaw 1 to make the construction compact and easy to assemble. In order to mount the torsion spring, a first cavity 16 is introduced into the stationary jaw 1. The first support point 12 and the torsion spring are mounted in the first cavity 16 and are covered by a first cover plate 17 that is screwed to the stationary jaw 1.

The pivot point 10 and the second support point 13 for joining are arc-shaped. This feature limits the movement about the axis of the second support point 13 in the pivot point 10 for engagement. This feature also causes the second support point 13 to return to the preset position after it has been detached from the pivot point 10 for engagement.

The actuating handle 6 includes an aperture 18 that is threaded into and attached to the aperture 18; there is a locking spring element 19 acting on the traction plates 7 that acts on the actuation plate 8 The upper one retracts the spring element 20; the traction plates 7 and the actuating plates 8 surround the sliding bar 5, and the locking spring element 19 and the return spring element 20 surround the coil spring of the sliding bar 5. In this configuration, the traction plate 7, the actuation plate 8, the lock spring member 19, and the return spring member 20 are held to the operating state by the slide bar 5. A second cavity 21 is introduced into the stationary support 2. The traction plate 7, the actuation plate 8, the locking spring element 19 and the return spring element 20 are mounted in the second cavity 21 by a second cover 22 that is screwed to the stationary support 2 cover. Connecting the second cavity and the first cavity causes a first support point of the actuation handle to extend to the stationary clamp.

The positioning grooves 23A, 23B are mounted in both end portions of the sliding bar 5, and the movable supporting member 4 includes a movable block 24 surrounding the sliding bar 5, the movable clamping jaw 3 being supported by a pivot pin 25. Connected to the movable block 24 such that the movable jaw 3 can move about an axis of the pivot pin 25 on the movable block 24 over a range of angles, and a lock is mounted on the movable jaw 3 a pin 26, a spring element 27 (more specifically, a torsion spring) connecting the movable jaw 3 and the movable block 24 is inserted into the locking pin 26 into a corresponding positioning groove, so that the entire movable support member 4 is locked to the slide bar, and the spring element 27 applied to the movable jaw 3 has the same orientation as the force applied to the movable jaw in the pressure mode. A small cover 34 is attached to the movable block 24 such that the spring element 27 can be mounted only by opening the small cover 34. Therefore, the entire movable support member can be removed from one end of the slide bar, and the sliding member 26 can be mounted on the sliding groove by sliding the movable jaw 3 against the elasticity of the spring member 27 to be mounted on the sliding groove. Inside the other end of the stick. In the configuration as shown in Figures 1 to 3, the movable support member 4 is mounted in the left end portion of the slide bar 5, which is suitable for being clamped by the stationary support member 2 and the movable support member 4 Clamp a workpiece. In the configuration as shown in Fig. 4, the movable support member 4 is mounted in the right end portion of the slide bar 5, which is suitable for supporting a workpiece by the stationary support member 2 and the movable support member 4. In particular, since the elasticity of the spring member 27 applied to the movable jaw 3 has the same direction as the force applied to the movable jaw in the pressure mode, the clamping force is stronger, and the locking pin 26 It is better to stay in the positioning groove of the sliding bar, which ensures a stable connection between the movable support 4 and the sliding bar 5. Pick up. For ease of removal and installation, the movable block 24 includes an aperture point 28 and the movable support 24 includes a compression point 29 that extends to one of the aperture points 28. The movable support member 4 can overcome the elasticity of the spring member 27 by pressing the compression point 29 to rotate the movable jaw 3 such that the locking pin 26 is dropped away from the positioning groove of the push or pull rod to be removed. A similar operation is applied to mount the movable support whereby the locking pin 26 is rotated an angle such that the movable block surrounds the slide bar and the locking pin is inserted into the positioning groove of the slide bar.

The positioning pins 30A, 30B are mounted on both ends of the sliding bar 5 corresponding to the positioning grooves, which guide the movable supporting member 4 so that when the movable supporting member 4 is mounted on the sliding bar, the locking pin It is perfectly oriented opposite the positioning groove.

The stationary support 2 is coupled to a release handle 31 opposite the stationary shank 9, and the release handle 31 includes a release point 32 for urging the traction plates 7. The unloading can be caused by merely fastening the stationary shank 9 and the release handle 31 such that the release point 32 pushes the traction plates 7 to detach from the sliding bar 5. Further, the release handle 31 is mounted between the stationary shank 9 and the actuating shank 6 and is coupled to the stationary support 2 by a pivot pin 33 which forms a compact configuration and which is easy to handle. Furthermore, the labor-saving effect can be achieved due to the full use of the lever.

The construction as shown in Figures 1 to 4 is a first embodiment of a clamp tool according to the invention. The stationary shank 9 and the actuating shank 6 are fastened for clamping a workpiece. Before the workpiece is clamped by the stationary support 2 and the movable support 4 and as shown in Fig. 2, the actuation handle 6 is moved about the axis of the first support point 12, each time the stationary handle is fastened Actuating plate 8 when moving the handle to make sliding bar 5 Shift to the right over a larger distance D1. When the actuating lever 6 is released, the actuating plate 8 is returned to the preset position by the return spring element 20. The fastening of the stationary shank and the actuating shank is repeated until the workpiece 35 is clamped by the stationary support 2 and the movable support 4, as shown in Fig. 3. The actuating shank 6 moves about the axis of the second support member 13 each time the stationary shank and the actuating shank are fastened. Whenever the stationary shank and the actuating shank are fastened, the sliding bar 5 is displaced by a small distance D2 by the actuating plate 8 to obtain a larger clamping force. When it is required to unload the workpiece from the clamp, the release can be caused by merely fastening the stationary handle 9 and the release handle 31 such that the release point 32 pushes the traction plates 7 to be detached from the sliding bar 5, and thus the sliding bar The lock is raised. The slide bar may move to the left or right such that the movable support 4 can be adjusted to an appropriate position. As shown in Fig. 4, for the workpiece to be supported by the stationary support 2 and the movable support 4, the operating system is similar to that shown in Figs. 2 and 3, and thus is not repeated here.

According to Figures 5 through 7, a second embodiment of a clamp tool of the present invention includes another lever 40 in the form of a lever 40 for adding a clamping force. The lever can be made of metal, but other materials are also possible. When using this second embodiment of the tool, an object is first firmly clamped with the strength of the individual force using the lever in the open position (see Figure 5), after which the lever is as crowded as possible as desired by the individual The pressure, for example halfway through (see Figure 6), or all the way to the end (see Figure 7), is also possible in the middle position to increase the clamping force as much as possible. When the lever 40 is pressed against the rest of the clamp tool and the lever is rotated about a rotational axis 41, it is located between two other parts of the tool (eg, between a clamp and a support that supports the clamp) One of the levers (not shown) is opposite to each other Slightly flexing, pressing other parts, etc., results in an increase in the clamping force in the pressure mode.

A second embodiment of a clamp tool generally includes at least one release handle 31. It is used to at least partially release a sliding bar 5 from a mechanism. However, no special features are required in accordance with the present application (ie, except for or more than at least one substantially stationary jaw 1, at least one movable jaw 3, at least one sliding rod 5, at least one movable handle 6 and at least one substantially stationary) The handle 9) is present on a second embodiment of a clamp tool. In other words, the lever 40 for increasing a clamping force can be present on the most basic clamping tool according to the invention and in the first embodiment of the most complex clamping tool according to the invention and all variations therebetween.

According to the present invention, when the tool is used, the positions of the support objects of the so-called stationary support 2 and the so-called stationary clamp 1 are substantially constant, respectively, and thus the terms "stationary support 2" and "stationary clamp" are respectively employed. 1". The position of the movable support 4 relative to the stationary support 2 and the position of the so-called movable clamp 3 relative to the stationary clamp 1 are respectively offset by the movement of the slide bar 5, and thus the term "movable support" is used respectively. 4" and "Removable Clip 3".

The present invention has the advantage that one advantage is achieved by the two support points mounted in the actuating handle. In the unloading mode, the movement of the actuating shank is to enable the axis about the first support point, whereby the actuating point of the actuating shank results in a quick result due to the proper lever relationship whenever the actuating shank is fastened. Large feed pressure for displacement. In the pressure mode, the movement of the actuating shank is enabled around the axis of the second support point, whereby the actuating point of the actuating shank acquires a stronger one due to the proper lever relationship whenever the actuating shank is fastened. Clamp force.

Another advantage is achieved by a positioning groove mounted in the two ends of the push or pull bar. The movable clamp is connected to the movable block by a pivot pin, and there is a locking pin inserted into the positioning groove by a spring element, which enables the movable support to be conveniently Pushing or pulling the rod to remove and/or the movable support can be mounted to the push or pull rod. The clamp tool can achieve both the clamp and the support functions by mounting the movable support member in either of the two ends of the slide bar. Moreover, in the pressure mode, the locking pin is forcibly inserted into the positioning groove by the clamping force, which promotes a stable connection between the movable support and the sliding bar and thus has a strong enough clip Clamping force.

Yet another advantage is achieved by adding a release handle. Unloading can be caused by only fastening the stationary handle and the release handle. In particular, the release handle is mounted between the stationary shank and the actuating shank, which forms a compact structure and makes it easy to handle. Furthermore, the labor-saving effect can be achieved due to the full use of the lever.

Yet another advantage is achieved by adding another device in the form of a lever for increasing a clamping force.
