The inner perimeter 21 of the hand guard sleeve 2 comprises a first inner perimeter 211 and a second inner perimeter 212 protruding out of the first inner perimeter 211 in order to allow a stepped height drop portion 22 to form between one end of the first inner perimeter 211 and one end of the second inner perimeter 212.
Accordingly, each one of the first guiding members 23 is a guiding slot (i.e.: the first guiding member 23 of the guiding slot type) formed at the second inner perimeter 212, and each one of the second guiding member 26 is a rib (i.e.: the second guiding member 26 of the rib type) protruding out of the outer perimeter 25. Furthermore, the stepped height drop portion 22 includes a notch 221 indented toward the axial direction A and corresponding to one of the first guiding members 23.
The gun barrel 3 is inserted into a location corresponding to the inner insertion portion 2a. The outer perimeter 31 of the gun barrel 3 adjacent to an inner end 301 thereof includes a plurality of first corresponding guiding members 33 circumferentially formed thereon, and each one of the first corresponding guiding members 33 is slidably attached to each one of the first guiding members 23 correspondingly. Preferably, the first guiding member 23 and the first corresponding guiding member 33 are configured to include three members respectively in order to achieve the effect of fool-proof.
In this embodiment, each one of the first corresponding guiding members 33 of the gun barrel 3 is described in detail based on the examples provided in the following: each one of the first corresponding guiding members 33 is a plurality of ribs (i.e.: the first corresponding guiding member 33 of the rib type) protruded out of the outer perimeter 31 of the gun barrel 3 in order to allow each one of the first corresponding guiding members 33 of the rib type to be slidably attached to each one of the first guiding members 23 of the guiding slot type correspondingly.
In addition, each one of the ribs slides from an open end (corresponding to one end 201 of the hand guard sleeve 2) of the guiding slot to reach a close end (corresponding to another end 202 of the hand guard sleeve 2) of the guiding slot along the axial direction A. In this embodiment, the example in which the outer perimeter 31 of the gun barrel 3 includes a blocking portion 32 protruded therefrom is used for illustration such that it allows the blocking portion 32 of the gun barrel 3 can be blocked at the stepped height drop portion 22 correspondingly in order to achieve the effect of precise positioning on the axial direction A. Furthermore, with the cooperation of the guidance, similar to a guiding track, between the first corresponding guiding member 33 and the first guiding member 23, the effect of precision positioning rotational angle can be achieved.
Preferably, the blocking portion 32 includes a restricting member 321 formed corresponding to a location of one of the first corresponding guiding members 33 and toward the axial direction A. In addition, the restricting member 321 corresponds to the aforementioned notch 221 in order to allow the restricting member 321 to be inserted into a location corresponding to the notch 221 via a press-fit method such that there is no loose space in order to prevent the gun barrel 3 from rotating relative to the hand guard sleeve 2 and to achieve a greater assembly precision.
