The mounting seat 20 is provided with a notch 201. The notch 201 can be in a long arc shape. The shape of the boss 11 is adapted to the shape of the notch 201. The boss 11 can be placed from the head end of the notch 201 and can be moved with the accessory 10 to various positions within the extension range of the notch 201. A limiting assembly 30 is connected to the rear end of the notch 201. The limiting assembly 30 is provided with a locking piece 31. An installation gap 301 is formed between the trigger locking piece 31 and the mounting seat 20 along the axial direction of the accessory 10. The installation gap 301 is placed within the range of the notch 201 and is provided for the boss 11 to extend therein. The locking piece 31 is used to limit the accessory 10 from being separated from the triggering piece of the mounting seat 20. The pressure plate 40 has a pressing portion 41. The pressing portion 41 is threadedly assembled on the mounting seat 20. The pressing portion 41 is used to drive the locking piece 31 to move along the axial direction of the accessory 10 so that the locking piece 31 and the boss 11 are pressed against or separated from each other.

[0040] By setting the mounting base 20, the limiting assembly 30 and the pressure plate 40 to cooperate with each other, the accessory 10 with the boss 11 can be installed. The mounting base 20 is provided with a recess 201 for the boss of the accessory to be placed. The user can move the accessory 10 so that the boss 11 can move within the extension range of the recess 201 to the installation gap 301 formed by the locking piece 31 and the mounting base 20. The user does not need to continuously support the accessory 10. The trigger member of the locking piece 31 can limit the boss 11 from being separated from the recess 201, so that the user can continue to assemble the pressure plate 40. Only one person is required to complete the installation of accessories 10 of different sizes, and the assembly between the accessory 10 and the connecting device is more convenient.

[0041] During the process of assembling the pressure plate 40 on the mounting base 20, the pressing portion 41 can also drive the locking piece 31 to move along the axial direction of the accessory 10 toward the direction adjacent to the boss 11 while rotating, so that the locking piece 31 presses against the boss 11, thereby limiting the movement of the boss 11, so that the accessory 10 is firmly installed on the connecting device.

[0042] During the process of removing the pressure plate 40 from the mounting seat 20, the pressing portion 41 can also drive the locking piece 31 to move along the axial direction of the accessory 10 in a direction away from the boss 11 while rotating, so as to separate the locking piece 31 from the boss 11, thereby facilitating the removal of the boss 11 from the recess 201 after leaving the mounting gap 301, and making the disassembly between the accessory 10 and the connecting device more convenient.

[0043] In one embodiment, please refer to Figures 2 to 4 The mounting seat 20 includes a shell 21 and a cover 22. A first opening 202 is formed in the middle of the shell 21. The first opening 202 is circular. Along the axial direction of the accessory 10, an extension portion 211 is provided on a portion of the inner circumferential wall of the shell 21 away from the pressure plate 40 at the first opening 202. A threaded portion 212 is provided on another portion of the inner circumferential wall of the shell 21 adjacent to the pressure plate 40 at the first opening 202. The recess 201 is opened in the extension portion 211. The cover 22 is connected to a side of the extension portion 211 away from the threaded portion 212. The cover 22 is used to prevent the accessory 10 from detaching from the mounting seat 20 after passing through the first opening 202 as a whole along the axial direction.

[0044] In application, the cover 22 includes a limit plate 221 and a positioning cover 222. The limit plate 221 is bolted to the outer shell 21.

The limit plate 221, the positioning cover 222 and the extension portion 211 together enclose a mounting groove, which is connected to the recess 201. The mounting groove is for the end of the accessory 10 to be inserted. After the pressure plate 40 is connected to the mounting seat 20, the accessory 10 can be limited from detaching from the mounting groove along the axial direction away from the mounting seat 20, thereby fixing the accessory 10 to the connecting device.

[0045] In application, the extension portion 211 and the threaded portion 212 are both annular and concentrically arranged. The extension portion 211 is closer to the center of the outer shell 21 than the threaded portion 212. One of the adjacent two sides of the pressing portion 41 is parallel to the extension portion 211. The other side of the adjacent two sides of the pressing portion 41 is provided with an external thread, and the threaded portion 212 is provided with an internal thread that matches the external thread, so that the pressing portion 41 can be threadedly assembled on the threaded portion 212 of the mounting seat 20.

[0046] Specifically, during the process of assembling the pressing portion 41 with the threaded portion 212, the pressing portion 41 rotates around the accessory 10 and moves axially along the accessory 10, so that the pressing portion 41 contacts the locking piece 31, and the pressing portion 41 exerts an extrusion effect on the locking piece 31, or the pressing portion 41 is separated from the locking piece 31, and the extrusion effect of the pressing portion 41 on the locking piece 31 disappears.

[0047] In application, there are multiple recesses 201 , and the multiple recesses 201 are arranged at intervals. Each recess 201 is provided with a limiting component 30 , so that it can be suitable for an accessory 10 provided with multiple bosses 11 .

[0048] Specifically, the number of the recesses 201 is not less than the number of the bosses 11 of the accessory 10 , and each boss 11 can be installed in a different recess 201 , respectively, to enhance the locking effect of the connection device on the accessory 10 and reduce the shaking of the accessory 10 .

[0049] In one embodiment, please refer to Figures 2 to 4 The locking member 31 includes a bending portion 311, a connecting portion 312 and a first movable portion. The bending portion 311 includes a first plate body and a second plate body that are vertically connected. The first plate body and the extending portion 211 are arranged parallel to each other to form an installation gap 301. The pressing portion 41 can drive the first plate body to move so that the first plate body exerts an extrusion effect on the boss 11. The second plate body is vertically connected to the connecting portion 312. Along the axial direction of the accessory 10, the first movable portion is installed on the side of the connecting portion 312 away from the bending portion 311.

The first cylinder 314 is sleeved in the second chamber. The opposite ends of the first elastic member 313 are respectively in contact with the bottom wall of the first chamber and the bottom wall of the second chamber.

[0051] During application, when the bending portion 311 is in the initial position, the size of the installation gap 301 is not less than the height of the boss 11. After the pressing portion 41 drives the bending portion 311 to move, the size of the installation gap 301 gradually decreases until the bending portion 311 is pressed against the boss 11. After the squeezing effect of the pressing portion 41 on the bending portion 311 disappears, the bending portion 311 is restored to the initial position under the elastic restoring force of the first elastic member 313, and the boss 11 can be moved out of the installation gap 301, so that the accessory 10 can be easily disassembled.

[0052] In one embodiment, please refer to Figures 2 to 4 The limiting assembly 30 is also provided with a trigger member 32, which includes a sliding portion 321, a trigger portion 322 and a second movable portion.
