In the present embodiment, the accommodating portion 15 is a stepped through hole formed in the casing 10.

The fixing mechanism 30 includes a holding member 31, a locking member 32, a lock lever 33, a positioning member 34, a first elastic member 35, a rotating shaft 36 and a second elastic member 37.

The holding member 31 includes a body 312 , an engaging portion 313 , and a connecting portion 315 . The engaging portion 313 and the connecting portion 315 are respectively disposed at two sides of one end of the body 312. The connecting portion 315 is fixed to the attachment 20 by screws (not shown). In the embodiment, the engaging portion 313 is a lug extending from the body 312, and the engaging hole 3132 is defined in the lug.

The locking member 32 includes a holding portion 321 , two connecting portions 323 and a base 325 . The holding portion 321 is substantially U-shaped and is formed with a first receiving groove 3211. A through hole 3212 communicating with the first receiving groove 3211 is respectively formed on opposite sides of the holding portion 321 . Each of the connecting portions 323 is substantially triangular, and the two sides thereof are respectively connected to the holding portion 321 and the base 325, and the two connecting portions 323 and the holding portion 321 and the base 325 form a second receiving groove 3233. A shaft hole 3231 is defined in each of the connecting portions 323. A boss 3251 is formed at the bottom of the base 325, and is just received in the receiving portion 15 of the housing 10.

The lock lever 33 includes a rod portion 331 and a resisting portion 334 provided at one end of the rod portion 331. An annular card slot 3312 is formed in the middle of the rod portion 331. The abutting portion 334 is substantially conical.

In this embodiment, the positioning member 34 is a snap spring, the first elastic member 35 is a cylindrical compression spring, and the second elastic member 37 is a torsion spring.

When the fixing mechanism 30 is assembled, the second elastic member 37 is received in the second receiving groove 3233 of the locking member 32. The base 325 of the locking member 32 is received in the receiving portion 15 of the housing 10 . The rotating shaft 36 passes through the shaft hole 161 of the rotating joint portion 16 of the casing 10, the shaft hole 3231 of the locking member 32, and the second elastic member 37. The first elastic member 35 is received in the first receiving groove 3211 of the locking member 32. The rod portion 331 of the lock lever 33 passes through the through hole 3212 of the locking member 32 and the first elastic member 35. The positioning member 34 is locked in the slot 3312 of the locking lever 33, so that the first elastic member 35 is abutted between the positioning member 34 and the side wall of the first receiving slot 3211 of the locking member 32.

The circuit board 40 is disposed on the housing 10 and is located at one end of the accessory device 20. A connector 41 electrically connected to the attachment 20 is provided on the circuit board 40.

Referring to FIG. 2 to FIG. 4 simultaneously, when the attachment 20 is installed, the attachment 20 is placed between the first positioning flange 11 and the second positioning flange 13 of the housing 10. The accessory device 20 is slid along the first positioning flange 11 and the second positioning flange 13 toward one end of the fixing mechanism 30, so that the abutting portion 334 of the locking bar 33 and the engaging portion 313 of the holding member 31 are abutted. The lever portion 331 of the lock lever 33 slides toward the base 325 of the latching member 32, so that the positioning member 34 compresses the first elastic member 35 until the resisting portion 334 of the lock lever 33 is received in the latching portion 313 of the latching member 31. In the hole 3132, the attachment 20 is fixed to the housing 10.

Referring to FIG. 2, FIG. 5 and FIG. 6, when the attachment 20 is removed, the attachment 20 is dragged along the first positioning flange 11 and the second positioning flange 13 toward one end away from the fixing mechanism 30 to make the locking component. 32 is rotated by the lock lever 33, and the second elastic member 37 is elastically deformed. When the connecting portion 323 of the locking member 32 abuts against the inclined portion 151 of the receiving portion 15 of the housing 10, the attachment device 20 is continuously dragged to engage the abutting portion 334 of the locking lever 33 from the holding member 31. The engaging hole 3132 of the portion 313 is disengaged. The abutting portion 334 of the lock lever 33 abuts against the engaging portion 313 of the latching member 31. The lever portion 331 of the lock lever 33 slides toward the base 325 of the latching member 32, so that the positioning member 34 compresses the first elastic member 35. Until the abutting portion 334 of the lock lever 33 is separated from the engaging portion 313 of the retaining member 31, the first elastic member 35 and the second elastic member 37 are restored and deformed, and the attachment 20 can be directly detached from the housing 10.

The fixing mechanism 30 of the present invention locks or separates the lock lever 33 and the retaining member 31 by the deformation and recovery of the first elastic member 35, thereby facilitating the attachment or detachment of the attachment device 20.

Further, the locking member 32 of the fixing mechanism 30 is rotatable relative to the housing 10, and the second elastic member 37 provides an elastic restoring force to the locking member 32, so that the locking rod 33 is inclined at an angle with respect to the holding member 31. After that, it can be automatically reset, so that the lock lever 33 is more conveniently held or separated from the retaining member 31, thereby making it easier to attach or detach the attachment device 20.

It can be understood that the first elastic member 35 is not limited to a cylindrical compression spring, and may be other elastic members. For example, the first elastic member 35 may also be a tension spring. In this case, the first elastic member 35 is disposed at the first position. The receiving groove 3211 is adjacent to the side wall of the abutting portion 334 of the lock lever 33 and the positioning member 34. The second elastic member 37 is not limited to the torsion spring, and may be other elastic members. For example, the second elastic member 37 is disposed between the base 325 of the locking member 32 and the bottom wall of the first receiving groove 3211 of the housing 10. compressed spring. The locking member 32 can also be slidably disposed on the housing 10, and the second elastic member 37 can be omitted at this time.
