All other embodiments, based on the embodiments herein, which would be apparent to one of ordinary skill in the art without making any inventive effort, are intended to be within the scope of the present application. In addition, the technical solutions of the embodiments may be combined with each other, but it is necessary to base that the technical solutions can be realized by those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be regarded as not exist and not within the protection scope of the present application.

Please refer to fig. 1-4, which illustrate embodiments of the present application: a horizontally adjustable platen mechanism is shown which is primarily used on power tool products such as cutting machines, miter saws and the like.

The horizontally adjustable pressing plate mechanism comprises a pressing plate 1 and a driving mechanism 5 for driving the pressing plate to move along the direction of a first axis S1, wherein the direction of the first axis S1 is approximately perpendicular to the extending direction of a backup plate 2 of the electric tool. The platen 1 is provided with a horizontal chute 11 extending in the direction of a second axis S2, wherein the second axis S2 is substantially perpendicular to the first axis S1.

The pressing plate further comprises a first locking piece 31 and a second locking piece 32 which are respectively arranged on two lateral surfaces of the pressing plate, the first locking piece 31 and the second locking piece 32 form a sliding part 3 for supporting the pressing plate 1, the pressing plate 1 can slide along a second axis S2 relative to the sliding part 3, and therefore the relative positions of the sliding part 3 and the pressing plate 2 on the second axis S2 can be adjusted, and accordingly pressing of different objects can be matched.

More specifically, the first locking piece 31 and the second locking piece 32 are kept locked by a locking piece 33, and the locking piece 33 is selected as a fastening screw in this embodiment. When the clamp plate 1 is used, the first locking piece 31 and the second locking piece 32 can be kept fastened, and when the clamp plate 1 needs to be adjusted, the fastening screw is properly loosened, so that the clamp plate 1 can move relative to the sliding part 3; alternatively, the first locking piece 31 and the second locking piece 32 can also maintain a certain locking force, and meanwhile, the relative movement of the pressing plate 1 is not affected, so that adjustment is realized.

In some embodiments, to support and fix the sliding portion 3, a pin 4 is further included, where the pin 4 sequentially passes through the first locking piece 31, the horizontal sliding groove 11, and the second locking piece 32, and an end of the pin 4 contacts the power tool backup plate 2 during use, for example, is fixedly connected to the power tool backup plate 2. Specifically, an insertion hole 21 is provided in the backup plate 2, and the end of the pin 4 is inserted into the insertion hole 21 to keep the position of the sliding portion 3 in the second axis S2 substantially fixed.

In some embodiments, to facilitate positioning of the sliding portion 3, a recess 12 surrounding the horizontal sliding slot 11 is formed on an outer edge of the horizontal sliding slot, and the recess 12 is used for placing the first locking piece 31 or the second locking piece 32.

In the present embodiment, the driving mechanism 5 mainly includes a fixing seat 51 and an adjusting screw 52; the first end of the adjusting screw 52 is provided with a knob 521, the second end is fixedly connected to the pressing plate 1, and in particular in the embodiment, the second end is fastened to the pressing plate 1 by a screw 522; the adjusting screw rod 52 is screwed on the fixing seat 51, and the pressing plate 1 is driven to move along the direction of the first axis S1 by rotating the adjusting screw rod 52.

As a further improved embodiment of the driving mechanism, the driving mechanism 5 further includes a quick-adjusting button 53, a pressing block 54 and a spring (not shown) which are disposed on the fixing base 51; the compression block 54 is provided with threads matched with the adjusting screw rod 52; the spring is used for driving the compression block 54 to be in threaded fit with the adjusting screw rod 52; the quick adjustment button 53 is used to drive the pressing block 54 to overcome the force of the spring, so that the pressing block 54 is disengaged from the adjusting screw 52. The quick-adjusting button 53 is pivotally connected to the fixed base 51 via a pivot 55, and the pressing block 54 moves longitudinally in the fixed base 51. During operation, in a normal state, the compression block 54 is always in threaded fit with the adjusting screw rod 52, and at the moment, the adjusting screw rod 52 is rotated to slowly drive the pressing plate 1 to move, so that the adjustment is relatively stable; when the distance between the pressing plate 1 and the backing plate 2 is longer, the quick adjustment button 53 can be pressed downwards, the pressing block 54 is driven to be separated from the fit with the adjusting screw rod 52 by the quick adjustment button 53, and at the moment, the quick displacement of the pressing plate 1 can be realized by only pulling or pushing the adjusting screw rod 52 along the direction of the first axis S1.

Thus, various embodiments of the present application have been described in detail. In order to avoid obscuring the concepts of the present application, some details known in the art are not described. How to implement the solutions disclosed herein will be fully apparent to those skilled in the art from the above description.
