The utility model discloses a rotary adjusting cutter which comprises a blade assembly, adjusting seat assemblies are fixedly arranged on the two sides of the blade assembly, an adjusting cover assembly is arranged on the outer side of each adjusting seat assembly in a threaded connection mode, a locking assembly is installed in each adjusting cover assembly, and each adjusting seat assembly comprises a first adjusting seat component. The adjusting cover assembly is screwed to the outer sides of the first adjusting seat component and the second adjusting seat component by rotating the adjusting cover assembly, and along with screwing of the adjusting cover assembly, the arc-shaped adjusting inserting plate can be gradually squeezed into the small gap positions of the outer sides of the first arc-shaped elastic locking block and the second arc-shaped elastic locking block; an arc-shaped elastic locking block I and an arc-shaped elastic locking block II are extruded to deform inwards, so that a locking anti-skid thread I and a locking anti-skid thread II are attached to the rotating shaft, and the cutter rotating shafts with different diameters can be locked; and then a plurality of sets of press-fit locking bolts are rotated, so that locking press-fit pieces at one ends of the press-fit locking bolts press the two sets of metal locking washers to tightly press the metal locking washers on the two sides of the adjusting seat assembly, further fastening and locking can be achieved, and use is more convenient.

The utility model discloses a compression locking device based on connecting rod operation, and relates to the field of cabinet body locking devices. The compression lock catch device based on connecting rod operation comprises a fixing base, a direction block and a buckle tongue, the direction block and the buckle tongue are arranged in the fixing base, the fixing base is provided with a first logic groove, a second logic groove and a third logic groove which are through, the direction block is arranged in the fixing base in a sliding mode, and the buckle tongue is hinged to the direction block. And the buckling tongue is driven by planar motion of the direction block to realize composite motion of first vertical motion and then horizontal motion through the second logic groove and the third logic groove. According to the compression lock catch device based on the connecting rod operation, it needs to be guaranteed that the buckle tongue vertically moves to a certain height and then transversely moves in the unlocking operation process, it needs to be guaranteed that the buckle tongue transversely moves to a certain position and then vertically moves in the locking operation process, and therefore in the actual operation process, unlocking is easy, and the locking effect is good. The locking operation is simple and convenient; and the sealing effect of the cabinet door is ensured.

A joinery article comprising a first joinery member (10), a second joinery member (20) and a third joinery member (30) which are mutually locked by a mechanical locking device comprising a dowel (31), an insertion recess (32) configured to receive the dowel (31) to inhibit displacement of the first joinery member (10) in a first direction relative to the second joinery member (20), a compressible locking element (40), a locking recess (50) configured to receive the compressible locking element (40) to inhibit displacement of the first joinery member (10) in a second direction relative to the second joinery member (20), and a locking mechanism configured to inhibit rotational displacement of the first joinery member (10) relative to the second joinery member (20).

This invention provides a self-locking steel clamp structure for a construction platform and its usage method. The structure includes a pier column, with a self-locking steel clamp on the outside of the pier column to support the construction platform. The self-locking steel clamp includes a hollow shell with openings at both ends for the pier column to pass through. An upper compression locking mechanism and a lower compression locking mechanism are arranged opposite each other within the hollow shell. The upper compression locking mechanism is fixed to the inner top wall of the hollow shell, while the lower compression locking mechanism is movably mounted on the inner bottom wall of the hollow shell. The pier column is clamped tightly by the mutual compression of the upper and lower compression locking mechanisms. Self-locking is achieved through the interaction between the upper and lower compression locking mechanisms. Furthermore, the greater the force on the upper platform, the greater the force between the locking mechanisms, further clamping the pier column and achieving self-locking without relying on other mechanical structures.
