Claim:
A locking assembly, for locking a first workpiece and a second workpiece, comprising: a locking member comprising a neck portion having a first end and a second end, a head portion connected to the first end of the neck portion, and a locking portion connected to the second end of the neck portion for locking with the first workpiece, wherein an outer diameter of the locking portion is larger than that of the neck portion; and a sleeve defining a through hole therein for holding and guiding the locking member, the through hole comprising a first part, a second part, and a third part communicating with the first part and the second part in that order, wherein the sleeve comprises a restricting portion extending out from an inner surface of the through hole between the second part and the third part, the locking portion is threaded and the restricting portion defines an inner screw threading thereon corresponding to the threading of the locking portion, such that when the locking portion of the locking member screwedly passes through the restricting portion of the sleeve, and finally the inner screw threading of the restricting portion blocks the locking portion from sliding out of the sleeve along a direction from the locking portion towards the head portion; and the head portion is received in the first part of the through hole, the sleeve defines a latching slot in an outer surface of the sleeve adjoining the first part, for latching with the second workpiece.
