Fig. 14 is a schematic view of fig. 13 in another state, when the limiting means 5 is withdrawn from the second inlet 413.

Referring to fig. 12 to 14 in combination with fig. 8 and 9, the limiting device 5 includes a limiting member 51 and a resetting member 52.

The limiting member 51 is slidably connected to the guide base 4. Specifically, the guide base 4 is provided with a sliding groove 42 communicating with the telescopic opening 43, and the stopper 51 is slidably provided in the sliding groove 42. Under the pressing of the guide block 32, the limiting member 51 can slide along the sliding groove 42 to a side away from the first inlet 412 and exit from the area of the second inlet 413.

The reset member 52 is disposed on the guide seat 4 and abuts against the limiting member 51, so as to drive the limiting member 51 to extend into the second inlet 413 through the telescopic opening 43. When the guide block 32 leaves or completely enters the guide groove 41, the reset piece 52 can drive the limit piece 51 to reset, and the limit piece slidably extends into and stops at the area of the second inlet 413.

In some embodiments, the return element 52 is a compression spring disposed within the sliding groove 42. One end of the pressure spring is abutted against the guide seat 4, and the other end of the pressure spring is abutted against the limiting piece 51. The tension of the compression spring can force the limiting member 51 to slide along the sliding groove 42 and extend into the expansion opening 43, as shown in fig. 13.

When the stopper 51 is pressed to slide out of the area of the second inlet 413, the pressing spring is compressed and deformed, and the state shown in fig. 14 is obtained. Therefore, when the guide block 32 completely enters the guide groove 41, the compressed spring is released, and the compressed spring can drive the limiting member 51 to slide and reset, and then extend into the second inlet 413 area along the sliding groove 42 again and stop, as shown in fig. 13.

When the compression spring is installed in the sliding groove 42, one end of the compression spring can be sleeved on the sleeve column 514, and the other end of the compression spring can be inserted into the sleeve 44.

When the limiting member 51 is extruded and slides out of the second inlet 413 region, the sleeve column 514 can drive the compression spring to be compressed and deformed, and both the sleeve column 514 and the compression spring are accommodated in the sleeve 44, so that the stability of the compression spring structure can be effectively ensured, and the overall expansion stroke and the required space length of the limiting device 5 can be reduced.

Referring to fig. 12 to 14, a tongue 511 is convexly disposed on a side wall of the limiting member 51 facing the expansion opening 43. When the reset piece 52 slides, the insertion tongue 511 can slide and extend into the second inlet 413.

In some embodiments, the limiting member 51 is provided with a limiting portion 512 protruding upward, and a stepped groove 513 is formed between the limiting portion 512 and the insertion tongue 511. When the tongue 511 extends into the second inlet 413 through the telescopic opening 43, the limiting part 512 can abut against the edge of the telescopic opening 43, as shown in fig. 13, the stepped groove 513 abuts against the edge of the telescopic opening 43, and the limiting part 512 can stop the limiting part 51 to prevent the limiting part from further entering the second inlet 413.

The limiting portion 512 is formed on the peripheral wall of the limiting member 51 in a protruding manner, and may be on the top, the bottom, the front side wall or the rear side wall of the limiting member 51.

Referring to fig. 9, 11 and 12, in some embodiments, the front side surface of the tongue 511 is provided with an inclined surface 5111, and the inclined surface 5111 gradually extends obliquely toward the rear side of the guide groove 41 in a direction gradually away from the expansion opening 43. When the guide block 32 presses the insertion tongue 511 at the second entrance 413, the guide block 32 can be engaged with the inclined surface 5111 of the insertion tongue 511, so that the insertion tongue 511 smoothly slides along the limiting member 51, and then exits from the second entrance 413 along the sliding groove 42.

Referring to fig. 6, 9 and 12, in some embodiments, the rear side of the tongue 511 is concavely provided with a smooth curved surface 5112. When the tongue 511 extends into the area of the second entrance 413, the smooth curved surface 5112 limits the guide block 32, so that the guide block 32 can move along the smooth curved surface 5112 and leave the guide groove 41 from the area of the first entrance 412.

In some embodiments, the smooth curved surface 5112 of the tongue 511 is concavely provided with a groove structure, and during the process of the guide block 32 leaving the guide groove 41, the guide block 32 can abut against the groove structure, which does not force the tongue 511 to exit the second entrance 413 along the sliding groove 42, but can move along the smooth curved surface 5112 and leave the guide groove 41 from the area of the first entrance 412, so that the tongue 511 can stably stop at the area of the second entrance 413. In addition, the reset element 52 can also provide a certain supporting force for the limiting element 51, so that the latch 511 can be stably stopped in the area of the second inlet 413.
