It can be understood that the sliding seat 311 and the connection plate 313 are arranged at an included angle, and the sliding seat 311 and the connection plate 313 can be selected as an integrally formed structure, so that the connection strength of the sliding seat 311 and the connection plate 313 can be improved, and the processing technology can be simplified. In the present embodiment, the sliding seat 311 is perpendicular to the connecting plate 313.

In the present embodiment, the direction in which the pressure maintaining assembly 32 moves forward or backward relative to the base 1 is the direction in which the pressure maintaining assembly 32 approaches or moves away from the first slide rail 111 on the base 1.

It is understood that the second slope surface 3141 may be directly disposed on the surface of the connection plate 313, which may simplify the structure of the connection plate 313.

It is understood that the thickness of the first guide block 312 is gradually increased in one direction of the first slide rail 211, thereby forming an inclination or slope. The thickness of the second guide block 314 is gradually increased in one direction of the first slide rail 211 to form an inclination or slope. Of course, in other embodiments, only a portion of the surfaces of the first and second guide blocks 312 and 314 may be tapered, i.e., both ends of the taper may be flat, where the flat surfaces at both ends of the taper have a height difference.

In order to facilitate the first roller 3221 of the first roller shaft 322 and the second roller 3241 of the second roller shaft 324 to simultaneously abut against the first slope surface 3121 and the second slope surface 3141 of the sliding table assembly 31, the first roller shaft 322 and the second roller shaft 324 are located on the same side of the fixing plate 321.

By slidably connecting the fixing block 323 with the base 1, the fixing block 323 can slide relative to the base 1 when the second roller 3241 slides along the second slope 3141; meanwhile, when the first roller 3221 slides along the first inclined surface 3121, the fixed block 323 generates a certain displacement with respect to the base 1 in a direction perpendicular to the base 1.

In one embodiment, as shown in fig. 1 and 2, the connection plate 313 is provided with an avoiding hole 3131 corresponding to the first roller shaft 322, and a first roller 3221 is disposed at an end of the first roller shaft 322 passing through the avoiding hole.

It can be understood that the fixing plate 321 is provided with a sliding chute corresponding to the second sliding rail 112, so that the second sliding rail 112 is limited in the sliding chute of the fixing plate 321, and is in sliding fit with the inner wall of the sliding chute, and when the second sliding rail 112 is used for guiding the sliding of the fixing plate 321, for example, the second sliding rail 112 can be used for realizing stable positioning assembly of the fixing plate 321, and the sliding stability of the fixing plate 321 is improved.

It can be understood that the second slide rail 112 is perpendicular to the first slide rail 111, so that the moving direction of the fixing plate 321 is different from the moving direction of the slide seat 311, thereby reducing the assembly space, and facilitating the cooperation between the first slope surface 3121 and the second slope surface 3141 of the sliding table assembly 31 and the first roller 3221 and the second roller 3241 of the pressure maintaining assembly 32.
