A spring is arranged on the main sleeve of the guide spring column, and the two ends of the spring respectively contact with the bottom end surface of the guide column and the end plate of the guide spring column. The seat body is slidably connected with a lifting drive plug-in, and the lifting drive plug-in can slide through the jack and the through hole. The inner end of the lifting drive plug-in is provided with a lifting drive inclined surface and an insertion part connected to the bottom end of the lifting drive inclined surface. The lifting drive inclined surface is used to contact the hole wall of the lifting drive hole; when the bottom surface of the zero patch contacts the bottom wall of the cavity, the part of the lifting drive hole connected with the through hole can be inserted by the insertion part.

As the lifting drive plug-in is gradually inserted inwardly, the lifting drive inclined surface contacts the hole wall of the lifting drive hole. Under the action of the lifting drive inclined surface, the guide column and the zero-sticking block are raised, and the guide spring column compresses the spring until the zero-sticking block contacts the bottom surface of the product and supports the product with zero-sticking, thereby positioning the product. When it is necessary to release the product, the lifting drive plug-in only needs to be pulled outward from the lifting drive hole, and the guide spring column, the guide column and the zero-sticking block are automatically lowered and reset under the action of the spring rebound force, so as to facilitate the next zero-sticking support. The utility model has the advantages of simple structure, low cost and convenient operation.

The bottom end of the guide column 9 can protrude into the lifting activity hole 5. The main body of the guide spring column 12 is covered with a spring 13, and the two ends of the spring 13 respectively contact the bottom end surface of the guide column 9 and the end plate of the guide spring column 12. The seat body 1 is slidably connected with a lifting drive plug-in 14, and the lifting drive plug-in 14 can slide through the jack 7 and the through hole 8. The inner end of the lifting drive plug-in 14 is provided with a lifting drive inclined surface 15 and an insertion portion 16 connected to the bottom end of the lifting drive inclined surface 15. The lifting drive inclined surface 15 is used to contact the hole wall of the lifting drive hole 10; when the bottom surface of the zero patch 11 contacts the bottom wall of the cavity 3, the part of the lifting drive hole 10 connected to the through hole 8 can be inserted by the insertion portion 16.

[0020] In actual application, when the lifting drive plug-in 14 is separated from the lifting drive hole 10, the spring 13 is in an extended state. Under the elastic force of the spring 13, the guide spring column 12, together with the guide column 9 and the zero patch 11, descends until the zero patch 11 is accommodated in the cavity 3 and contacts the bottom wall of the cavity 3. At this time, after the product 22 is placed in the product profiling cavity 2, the lifting drive plug-in 14 is inserted (inserted inwardly) in the direction close to the lifting drive hole 10, so that the insertion portion 16 of the lifting drive plug-in 14 is first inserted into the part of the gap connecting the lifting drive hole 10 and the through hole 8. As the lifting drive plug-in 14 is gradually inserted inwardly, the lifting drive inclined surface 15 contacts the hole wall of the lifting drive hole 10. Under the action of the lifting drive inclined surface 15, the guide column 9 and the zero patch 11 rise, and the guide spring column 12 compresses the spring 13 until the zero patch 11 contacts the bottom surface of the product 22 and supports the product 22 with zero patch, thereby supporting and positioning the product 22.

In addition, the lifting drive inclined surface 15 can drive the lifting displacement of the zero-sticking block 11 according to the actual situation to meet the different tolerance positioning requirements of the product 22.

[0021] The utility model has a simple structure, low cost and convenient operation. The lifting driving inclined plane 15 can drive the lifting displacement of the zero patch block 11 according to actual conditions to meet the different tolerance positioning requirements of the product 22.

[0022] In this embodiment, a sliding sleeve 17 is embedded in the socket 7, and the lifting drive plug-in 14 slides through the sliding sleeve 17. When the lifting drive plug-in 14 is driven to reciprocate (when the lifting drive plug-in 14 is pushed or pulled), the sliding sleeve 17 guides the lifting drive plug-in 14, thereby improving the moving stability of the lifting drive plug-in 14.

[0023] In this embodiment, a limiting column 18 is provided in the sliding sleeve 17, and a sliding limiting groove 19 is recessed in the side wall of the lifting drive plug-in 14, and the limiting column 18 is inserted into the sliding limiting groove 19. When the lifting drive plug-in 14 is pushed or pulled, the limiting column 18 moves in the sliding limiting groove 19, which, on the one hand, further improves the moving stability of the lifting drive plug-in 14, and on the other hand, the sliding limiting groove 19 limits the translation amount of the lifting drive plug-in 14 to prevent the lifting drive plug-in 14 from being separated from the sliding sleeve 17.

[0024] In this embodiment, a pull ring 20 is provided at the outer end of the lifting drive plug-in 14 . The design of the pull ring 20 facilitates the operator to push and pull the lifting drive plug-in 14 .

[0025] In this embodiment, the top end of the guide spring column 12 is threadedly connected to the guide column 9; this structural design not only makes the connection between the guide spring column 12 and the guide column 9 firm, but also makes the disassembly and maintenance of the spring 13, the guide spring column 12 and the guide column 9 convenient.

[0026] In this embodiment, the inserting portion 16 is provided with an arc guide surface 21. The provision of the arc guide surface 21 facilitates the inserting portion 16 to be inserted into the portion of the gap connecting the lifting drive hole 10 and the via hole 8, and reduces friction resistance.

[0027] All technical features in this embodiment can be freely combined according to actual needs.

[0028] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
