The processing mechanisms adopted in the embodiment are all handheld movable devices, and are not provided with fixing mechanisms, so that the field processing is facilitated.

Specifically, as shown in fig. 1, which shows a specific structure of the clamp when the clamp is opened, it can be seen that the whole clamp includes a fixed frame 1 as a main body component, two slide rail frames 5 are provided on the fixed frame 1, and each slide rail frame 5 is correspondingly provided with a clamping member capable of sliding on the slide rail frame 5.

The fixing frame 1 is a plate structure, the lower part of which is a flat surface and is directly contacted with a target object. And the upper part of the hollow groove is provided with a plurality of hollow grooves, so that the whole mass is reduced on the premise of ensuring certain structural strength.

Two auxiliary lug structures protruding outwards are arranged on one side of the fixed frame 1, and an avoidance groove 10 for a processing part of the processing mechanism to pass through is formed between the two auxiliary lugs.

The upper surface of the fixed mount 1 is further provided with two mounting seats 8 for mounting the guide rail 7, and the processing mechanism is sleeved on the guide rail 7 and can slide along the guide rail 7. That is to say, one end of the guide rail 7 is fixed in the mounting seat 8, and an expanded end for limiting the processing mechanism to slide out is arranged at the other end of the guide rail 7, and the expanded end and the guide rail 7 are detachably connected through a bolt. The machining mechanism is provided with a sliding structure connected with the guide rail 7, the sliding structure is sleeved with the guide rail 7 to limit the machining mechanism, and the sliding structure is also detachably connected with the machining mechanism.

The existing clamps are all fixed structures fixed on a fixed surface, and the target object is placed on the clamp to adjust the clamping piece, and is supported by a structure similar to the fixed frame 1 in the embodiment. However, since the processing mechanism connected in this embodiment is a handheld structure, and the fixing frame 1 is connected to the processing mechanism for limiting, the whole clamp covers the target object from above, and then the clamping member is moved to perform clamping operation.

In particular, in the present embodiment, the guide rail 7 has an arc-shaped strip structure, and the entire jig is used as a reference object, and when the processing mechanism is moved, the moving track thereof is arc-shaped, so that the moving track of the working member passing through the escape groove 10 on the target object is also arc-shaped. The processing mechanism can meet the same processing requirements, such as curved surface processing of circular pipes or arc-shaped pieces, or arc-shaped hole or arc-shaped groove processing of homogeneous raw materials.

The operation principle is as follows:

firstly, the clamping pieces on the two sides of the fixing frame 1 are loosened to move towards the two sides, and then the processing mechanism is stretched to the position farthest away from the clamp. The processing machine is then lifted so that the holder 1 is positioned directly above the object placed on the floor. Then the fixing frame 1 is pressed against the target object, and then the clamping pieces on the two sides are operated to move towards the middle. At this time, the clamping piece on one side can be moved to abut against the target object and operated to be arranged on the clamping piece for locking, and then the clamping piece on the other side is moved towards the middle until the target object abuts against and then is locked. At this time, the operator can move the processing mechanism to process the target object, lift the processing mechanism after processing, and release the two locking mechanisms 4, thereby completing the single processing.

It should be noted that, in the present embodiment, different technical terms are used for the two clamping members, which are only used for distinguishing and displaying, so that the whole clamping structure can be more intuitively understood. Those skilled in the art should recognize that in the solution of using multiple clamping members, the multiple clamping members can use the same size material, and the different or the same clamping member structure is a simple variant of this embodiment by arranging the clamping members in different directions to achieve a better clamping effect.

The fixed frame 1 is provided with a rectangular mounting groove 6; the slide rail frame 5 is of a rod-shaped structure, and one end part of the slide rail frame is arranged in the mounting groove 6 and is detachably connected with the fixed frame 1. Each clamping piece is correspondingly provided with an independent slide rail frame 5, the two slide rail frames 5 are arranged in parallel, and the extending direction of the slide rail frames 5 is parallel to the clamping surface of the fixing frame 1. The fixed frame 1 is provided with an avoiding groove 10 for a processing part of the processing mechanism to penetrate into the clamping space.

In fig. 6, 7, 9 and 10, the structure of the clamping member is shown from all directions separately, the clamping member in this embodiment includes a clamping plate 11 structure with a side surface shaped like an L, a stop block 12 and a guide seat 13 are arranged on the upper surface of the clamping plate 11, the stop block 12 and the guide seat 13 are arranged on the same straight line, the guide seat 13 is sleeved on the slide rail frame 5, and the stop block 12 is used for limiting the clamping member from excessively moving towards the middle of the fixing frame 1. When the clamping member moves towards the fixing frame 1, the stopping block 12 is finally stopped against the inner wall surface of the mounting groove 6.

The guide seat 13 shown in the figure is provided with a rectangular hole, and the slide rail frame 5 is a rod-shaped structure with a rectangular cross section, so that the clamping piece can be limited to do linear reciprocating motion only through the rectangular rod piece structure.

And the clamping plate 11 has a certain width and thus a large clamping surface area. The top plane of the clamping plate 11 is parallel to the sliding direction thereof, and the included angle between the clamping surface and the surface provided with the stop block 12 is smaller than 90 degrees, so that in the state of fig. 1, a wedge-shaped structure is formed between the first clamping piece 2 and the second clamping piece 3, so that the clamping device is applicable to wood processing of different shapes, including cylindrical and other polygonal structures.
