To form a stable rotational connection of the rotating block 71 and the transverse fixing bracket 5 by means of the rotating ring 711.
The rotating block 71 is provided with an X-direction clamping groove 712, the X-direction clamping groove 712 is a stepped groove or a dovetail groove, and the upper end of the pressing plate 73 is adapted to and slidingly connected with the X-direction clamping groove 712. The clamping connection to the upper end of the pressing plate 73 is formed through the X-direction clamping groove 712, so that the pressing plate 73 is ensured not to be separated from the rotating block 71.
In the embodiment of the present application, a hexagonal hole 741 into which a hexagonal wrench is inserted is formed in the head of the screw 74, and the screw 74 is rotated by the hexagonal wrench in such a manner that the hexagonal wrench is inserted into the hexagonal hole 741.
As a parallel scheme of the embodiment of the application, the pressing assembly 7 can also adopt a chuck, wherein the chuck is commonly provided with a three-jaw chuck, a four-jaw chuck and the like, and the force application on the wall of the rod hole 111 is realized through the jaws of the chuck. However, in this way, the pawl may not enter the rod hole 111 because of the limited diameter of the rod hole 111, which may affect the use effect.
The rotation driving assembly 8 includes a second motor 81 mounted at an end of the transverse fixing plate 51 and a driving gear 82 connected to an output end of the second motor 81 through a gear box transmission, the driving gear 82 is rotatably connected to the transverse fixing plate 51 through a rotation shaft, and external teeth (not shown) adapted to and engaged with the driving gear 82 are fixed at an outer side of the rotation block 71.
So as to drive the driving gear 82 to rotate through the second motor 81, thereby driving the rotating block 71 to rotate.
A bevel gear set is disposed within the gear box, wherein one bevel gear is fixedly connected coaxially with the shaft of the drive gear 82.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
