[0042] As shown in Figure 1 、 Figure 7 and Figure 9 , the twist head columnar body 450 is provided with a gasket installation groove 451, and a round nut stop gasket 461 is installed in the gasket installation groove 451, wherein the gasket installation groove 451 is located above the limiting fastener 46, and the limiting fastener 46 is a round nut.

[0043] As shown in Figure 1 、 Figure 4As shown, the twist head special-shaped end 452 has a cuboid locking portion 4520. As shown in Figure 6 and Figure 7 As shown, when the twist head special-shaped end 452 is in the locked position, the cuboid locking portion 4520 is arranged above the rectangular locking hole 12 of the locked pair of workpieces to be staggered with the rectangular locking hole 12, so as to be unable to be detached from the rectangular locking hole 12; as shown in Figure 8 and Figure 9 When the twist head special-shaped end 452 is in the unlocked position, the cuboid locking portion 4520 is opposite to the rectangular locking hole 12 of the locked pair of workpieces, so as to be able to be detached from the rectangular locking hole 12.

[0044] As shown in Figures 1 to 4 In the present embodiment, the center support column 432 of the floating plate 43 is configured as a rectangular column body capable of penetrating the rectangular locking hole 12 of the locked pair of workpieces, and when the twist head special-shaped end 452 is in the locked position, the cuboid locking portion 4520 of the twist head special-shaped end 452 is crosswise crossed with the center support column 432 in the form of the rectangular column body, so as to be staggered by 90°; when the twist head special-shaped end 452 is in the unlocked position, the cuboid locking portion 4520 thereof is aligned with the center support column 432 in the form of the rectangular column body. Through the structural arrangement, the twist head special-shaped end 452 can be supported on the center support column 432 of the floating plate 43 in both the locked position and the unlocked position.

[0045] It should be noted that, Figure 5 One application scenario of the detachable twist lock of the present embodiment is shown, which is applied to the cross beam leg 1 and the leg support 2 of the wind power blade mold joint root automatic polishing machine 100, and is used for auxiliary connection of the cross beam leg 1 and the leg support 2 in addition to the quick clamp 3 for quickly connecting the cross beam leg 1 and the leg support 2. As shown in Figures 5 to 9 The bottom of the cross beam leg 1 has a bottom plate 10 with an upper rectangular through hole, and the top of the leg support 2 has a top plate 20 with a lower rectangular through hole, the upper rectangular through hole and the lower rectangular through hole are arranged opposite to each other to form a rectangular through hole, the bottom plate 10 and the top plate 20 are a locked pair of workpieces, and the rectangular through hole constitutes the rectangular locking hole 12 of the locked pair of workpieces. As shown in Figure 6 and Figure 8As shown, the detachable twist lock 4 is installed on the top plate 20 of the outrigger bracket 2. Specifically, the floating plate 43 of the detachable twist lock 4 is installed on the top plate 20 of the outrigger bracket 2 from below via fastening bolts (not shown). In the locked position, the central support column 432 of the floating plate 43 passes through the rectangular through hole, i.e., the rectangular lock hole 12, and the twist head shaped end 452 supported on it is located above the bottom plate 10 of the crossbeam leg 1 and spans the rectangular lock hole 12, thereby locking the crossbeam leg 1 and the outrigger bracket 2 together. In the unlocked position, the twist head shaped end 452... The shaped end 452 is aligned with the rectangular lock hole 12, so that the shaped end 452 no longer interferes with the base plate 20 of the crossbeam leg 2, thereby unlocking the lock on the crossbeam leg 1 and the leg bracket 2. In other words, under this condition, the crossbeam leg 1 can move upward to disengage from the lock on the leg bracket 2, or the floating plate 43 of the detachable twist lock 4 can be removed from the top plate 20 of the leg bracket 2. Then the entire detachable twist lock 4 can disengage downward from the rectangular through hole 12, thereby unlocking the lock on the crossbeam leg 1 and the leg bracket 2.

[0046] like Figure 1 As shown, in this embodiment, the toggle head cylindrical body 450 has a round nut mounting portion 456 below the washer mounting groove 451. The outer circumferential surface of the round nut mounting portion 456 is provided with an external thread to cooperate with the limiting fastener 46. Furthermore, the toggle head cylindrical body 450 has a handle bearing portion 457 below the round nut mounting portion 456. The diameter of the handle bearing portion 457 is smaller than the diameter of the round nut mounting portion 456, so that the limiting fastener 46 can pass smoothly through the handle bearing portion 457 and be tightened onto the round nut mounting portion 456.

[0047] For example Figure 1 As shown, in this embodiment, the handle 47 has a handle mounting portion 470 with both sides being flat at one end. The handle bearing portion 457 of the toggle head cylindrical body 450 is provided with a longitudinally extending handle operating slot 4570 corresponding to the handle mounting portion 470. The handle mounting portion 470 of the handle 47 is mounted on the toggle head cylindrical body 450 within the handle operating slot 4570 via a connecting bolt (not shown, but it passes through the bolt hole 475 on the handle 47 and the bolt hole 458 on the toggle head 45). Thus, the handle 47 can drive the toggle head 45 to rotate, and its handle mounting portion 470 can pivot around the connecting bolt within the handle operating slot 4570, thereby allowing the handle 47 to pivot around the connecting bolt to move out of or into the handle limiting space 415 on the fixing plate 41.

[0048] like Figure 7 and Figure 9As shown, in the present embodiment, the floating plate 43 is adapted to be detachably fixed on the bottom surface of the lower one of the pair of workpieces being locked, and in particular, the floating plate 43 is adapted to be detachably mounted on the top plate 20 of the leg support 2 via fastening bolts (not shown) through the threaded holes 431 (see Figure 4 ) thereon.

[0049] Further as shown Figure 1 In the present embodiment, the pair of support columns 412 of the fixed plate 41 are spaced apart and provided with a pair of column center holes 4120 therethrough, the fixing bolt 42 connecting the fixed plate 41 and the floating plate 43 together is a hexagonal cup head shoulder bolt, and the floating plate 43 is correspondingly provided with a pair of bolt fixing holes 434, the fixing bolt 42 fastening in the bolt fixing holes 434 from the bottom of the fixed plate 41 through the column center holes 4120.

[0050] Further as shown Figure 1 In the present embodiment, the fixed plate 41 is provided with a second center through hole 410 corresponding to the first center through hole 430, the second center through hole 410 is arranged to pass through the head of the column body 450, and the second center through hole 410 is located between the pair of support columns 412. The arrangement of the second center through hole 410 makes the installation of the head 45 more convenient.
