The area of the accommodating space 12 is larger than the swept area of the handle chuck 231 during rotation, and the normal line of the section of the accommodating space 12 coincides with or is parallel to the rotation axis of the handle chuck 233, so that the handle chuck 231 can rotate in the accommodating space 12 by a predetermined angle, and the condition that the handle chuck 231 interferes with the side wall of the accommodating space 12 cannot occur.
Referring to fig. 5, 6 and 7, in this embodiment, the lower connecting member 230 is formed with a first cylindrical cavity 233 with an upward opening, the upper connecting member 220 is formed with a second cylindrical cavity 221 with an upward opening, the rotary self-locking device 240 includes a locking disc 241 and at least two guiding rods 242, each guiding rod 242 has one end fixed to the bottom of the first cylindrical cavity 233 and the other end flush with the lower end surface of the upper connecting member 220, the guiding rods 242 are symmetrically distributed along the central axis of the first cylindrical cavity 233, the locking disc 241 is slidably connected to the guiding rods 242, an elastic member 243 is sleeved on the guiding rod 242 between the lower surface of the locking disc 241 and the bottom surface of the first cylindrical cavity 233, the elastic member 243 is used for abutting against the locking disc 241 and making the upper surface of the locking disc 241 flush with the lower end surface of the upper connecting member 220, an engaging device 250 is arranged between the upper surface of the locking disc 241 and the lower end surface of the upper connecting member 220, the rotational self-locking device 240 further comprises a pressing member 244 for driving the locking disc 241 to move downwards, the pressing member 244 being disposed in the second cylindrical cavity 221.
With the above technical solution, by providing at least two guide rods 242, the locking disk 241 can be limited in the first cylindrical cavity 233, and can only move up and down in the first cylindrical cavity 233 along the guide rods 242, and cannot rotate horizontally. The top end of the guide bar 242 is flush with the bottom surface of the upper link 220, whereby the locking disk 241 can be completely confined between the upper link 220 and the lower link 230 and the locking disk 241 is prevented from being removed from the guide bar 242. By providing the elastic member 243 on the guide rod 242, in an initial state, two ends of the elastic member 243 respectively abut against the bottom surface of the first cylindrical cavity 233 and the lower surface of the locking disc 241, and further, under the elastic force of the elastic member 243, the upper surface of the locking disc 241 is flush with the lower surface of the upper connecting member 220, so that the engaging device 250 causes the upper connecting member 220 and the locking disc 241 to be engaged and locked with each other, and the locking disc 241 is connected with the lower connecting member 230 through the guide rod 242, so that the upper connecting member 220 and the lower connecting member 230 cannot horizontally rotate. When the lower connecting member 230 needs to rotate, the pressing member 244 is pressed to drive the locking disc 241 to move downwards along the guide rod 242, so that the locking disc 241 is separated from the upper connecting member 220, the lower connecting member 230 can be rotated, and the lower connecting member 230 drives the handle chuck 231 to rotate in the rotating process.

By adopting the technical scheme, the locking disc 241 is separated from the upper connecting piece 220 by pressing the pressing piece 244, and when the lower connecting piece 230 rotates, two groups of the convex parts 251 are horizontally and symmetrically arranged, the concave parts 252 are arranged in four groups, and two adjacent groups form an included angle of 90 degrees, so that the lower connecting piece 230 rotates 90 degrees, the lower connecting piece 230 drives the locking disc 241 to rotate 90 degrees, and the pressing piece 244 is loosened at the moment, so that the concave parts 252 on the locking disc 241 are matched with the convex parts 251 on the upper connecting piece 220, therefore, the handle chuck 231 can rotate 90 degrees under the rotation of the lower connecting piece 230, and the handle chuck 231 is inserted into the mounting hole 11 and then rotates 90 degrees in the accommodating space 12 of the mounting plate 1, and finally the locking of the handle chuck 231 and the mounting plate 1 is realized. When the handle 2 needs to be disassembled, the lower connecting piece 230 is rotated in the opposite direction by 90 degrees only by pressing the pressing piece 244, so that the handle chuck 231 can be driven to rotate in the opposite direction by 90 degrees, and the handle chuck 231 is separated from the mounting hole 11, thereby realizing the disassembly of the handle 2 and the mounting plate 1.
As a second embodiment, four sets of concave portions 252 are provided on the lower end surface of the upper connecting member 220, and the convex portions 251 are symmetrically distributed around the central axis of the second cylindrical cavity 221, two sets of convex portions 251 are provided on the upper surface of the locking disk 241, and the concave portions 252 are symmetrically distributed around the central axis of the locking disk 241.
