The sliding bracket (4) has a front end, a rear end, a front hook (23), a pair of rear hooks (24), a support panel (25), an extension tab (26) and a latch (27). The front hook (23) is made on the front end of the sliding bracket (4), it hooks the shoulder (20) on the casing (16) of the core assembly (3). The rear hooks (24) are made at the rear end of the sliding bracket (4). The support panel (25) is made on the sliding bracket (4) and abuts against the rear end of the casing (16) of the core assembly (3). An extension tab (26) is made on the support panel (25) of the sliding bracket (4), which extends in the opposite direction from this panel. On the extension tab (26), a latch (27) is made.

The mechanism for pushing and pulling back (5) is mounted on a sliding bracket (4), it selectively drives the core assembly for installation forward or backward and has a shaft (28), cylinder (29) and bias

element. The shaft (28) is made hollow and tubular, mounted for sliding and rotation around the extension tab (26) on the sliding bracket (4) and includes a front end, a rear end, an annular flange and a plurality of protrusions (31). An annular flange is made on the shaft (28), which extends radially from this shaft near the front end of the shaft (28) and has a rear end and many keys. The dowels extend back from the rear end of the annular flange and are divided into two sets of alternating dowels. The projections (31) are made on the annular flange, which extend radially from the annular flange on the shaft (28), correspond to alternating keys of the same set, and each protrusion (31) has a rear end with an inclined surface. The cylinder (29) is made hollow and tubular, mounted to slide and rotate around the shaft (28), abuts against the annular flange, engaged and held by the latch (27) on the extension tab (26) and includes the front end, rear end (32), many keyways and many centering protrusions (33). The rear end (32) of the cylinder (29) is engaged and held by the latch (27) to prevent the mechanism (5) from sliding out and pulling back out of the sliding bracket (4). The keyways are made at the front end of the cylinder (29) and selectively engage with the keys on the shaft (28), respectively. The centering protrusions (33) are made on the cylinder (29) and radially extend from this cylinder, while they are respectively placed between adjacent keyways grooves. The biasing element may be a spring (30), which is fixed around the extension tab (26) and installed between the support panel (25) on the sliding bracket (4) and the front end of the shaft (28).

The rear cover (6) is longitudinal, mounted on the front cover (2) and has a front end, a rear end, a camera, a lower locking hook (34), a pair of guide grooves (35), a mounting hole, many ribs (36), many grooves (37), strip (38) and clamp (39). The camera is made in the back cover (6) and has a front inner wall (40), as shown in Fig.5. The lower locking hook (34) is made on the front end of the rear cover (6) and pinched in the locking groove (12) in the lower part of the front cover (2). Guide grooves (35) are made in the front end of the rear cover (6), communicated with the camera, and with them with the possibility of sliding

rear hooks (24) on the sliding bracket (4) respectively. The mounting hole is made longitudinal in the back cover (6), the cylinder (29) and the shaft (28) enter it with the possibility of sliding, the hole has an inner surface. The ribs (36) are made on the inner surface of the mounting hole and radially extend from this inner surface, with each rib (36) having a front end with an inclined surface corresponding to the inclined surface on each protrusion (31) on the shaft (28). Grooves (37) are made in the inner surface of the mounting hole respectively between adjacent ribs (36), and centering protrusions (33) on the cylinder (29) respectively slide into them so that the cylinder (29) cannot rotate in the mounting hole . The grooves (37) are divided into two sets of alternating grooves (37). Each of the alternating grooves (37) of one set has a block (41) made in the groove (37). In cases where alternating grooves (37) with pads (41) engage respectively with protrusions (31) on the shaft (28), pads (41) respectively exert pressure on the protrusions (31) to hold the sliding bracket (4) and the core assembly (3) in the forward position relative to the front cover (2) to extend the head (19) of the core assembly (3) from the front cover (2), as shown in FIG. 6. In cases where alternating grooves (37) without pads (41) respectively engage with the protrusions (31), the head moves back into the front cover (2). A strip (38) is made at the front end of the rear cover (6), extending forward from this front end, the strip (38) is slidably mounted in one of the guide recesses (13) in the front cover (2) and has a retractable foot (42) and side locking hook (43). The retractable foot (42) is made on the strip (38) and has a distal end. The lateral locking hook (43) is made at the remote end and pinched in the locking hole (14) on the front cover (2). The clip (39) is made on the back cover (6) and can be riveted to the breast pocket of the shirt.

The rear cap (7) is mounted on the rear end of the rear cover (6).

The spring (8) is installed in the chamber in the lower cover between the front inner wall (40) and the rear hooks (24) on the sliding bracket (4) and is attached using the rear hooks (24).

As shown in FIGS. 5 and 6, the user pushes the convex portion on the core assembly (3) forward and compresses the spring (8) between the rear hooks (24) of the sliding bracket (4) and the inner wall (40) of the back cover (6) for extending the head (19) through the front hole (10) in the front cover (2). The sliding bracket (4) is driven by the assembly core (3) to move forward, and the protrusions (31) on the shaft (28) move forward from the alternating grooves (37) without pads (41) in the mounting hole. At the same time, the dowels on the shaft (28) respectively fully engage with the keyways in the cylinder (29), causing the shaft (28) to rotate slightly so that the protrusions (31) respectively coincide with the alternating ribs (36). In cases where the user releases the core assembly (3), the core assembly (3) moves slightly backward due to the restoring force of the spring (8) between the sliding bracket (4) and the back cover (6). At the same time, the inclined surfaces of the protrusions (31) on the shaft (28) slide respectively along the inclined surfaces of the ribs (36) in the back cover (6), thereby promoting further rotation of the shaft (28). Then, the protrusions (31) on the shaft (28), respectively, engage with alternating grooves (37) with blocks (41), and are accordingly blocked by blocks (41), which does not allow them to make a completely sliding movement into alternating grooves (37). As a result, the core assembly (3) and the sliding bracket (4) cannot move backward, and the head continues to be held outside the front cover (2). In cases where the user again pushes the assembly core (3) forward and then releases the core assembly (3), the protrusions (31) respectively fully extend into the alternating grooves (37) without pads (41) due to the restoring force of the spring ( 8) between the sliding bracket (4) and the back cover (6). The sliding bracket (4) and the core assembly (3) slide backwards to retract the heads (19) into the front cover (2). Retracting the heads (19) in the front cover (2) prevents dust from settling on the correction tape on the head (19).

The user can push the button (44) or push the convex part of the core assembly (3) to push the head (19) out of the front cover (2). In cases where the user presses the button (44) again

or pushes the convex part, the head (19) moves back into the front cover, which prevents the accumulation of dust on the correction tape on the head. As a result, the use of the device for feeding the correction tape becomes convenient and efficient.
