Regarding the technical means and the structure used by the present invention to achieve the objectives, I would like to cooperate with the embodiments shown in FIGS. 1 to 9 for a detailed description as follows: As shown in FIGS. 1 to 4, the embodiments The gripper structure includes a cylindrical body 10 which is provided with a valve stem 11. The bottom of the valve stem 11 is pivotally provided with a clamping jaw 20 relative to the bottom side of the cylindrical body 10. When the valve stem 11 is in a cylindrical shape When the body 10 moves up and down, the clamping jaws 20 can be synchronously folded and unfolded; the ends of the clamping jaws 20 are pivotally connected to a clamping member 30 by a shaft 21, so that the clamping member 30 The shaft 21 can be rotated upward or downward as a fulcrum. A clamping surface 31 is provided on the inner side of the clamping member 30, and the clamping surface 31 also has an anti-slip effect.

According to the above, the preferred embodiment is that the clamping member 30 is made of a material with anti-skid effect (such as rubber and silicone).

According to the above, as shown in FIGS. 3 and 4, the preferred embodiment is that the clamping surface 31 of the clamping member 30 is curved.

With the above structure, since the clamping member 30 uses the shaft 12 as a fulcrum, the clamping member 30 can freely deflect upward or downward, and when the clamping jaw 20 of the present invention starts to close and the clamping member 30 collides When the product is touched, the clamping member 30 can start to deflect according to the arc of the surface of the product that is touched (as shown in FIG. 5), and at the same time, the clamping jaw 20 continues to close and apply pressure. The clamping surface 31 can be abutted and clamped on the surface of the product (as shown in Figure 6), and because the clamping surface 31 of the clamping member 30 has an anti-slip effect, when the gripper of the present invention rises and moves During the process, the goods will not fall off, to ensure that players and buyers can get the goods.

Since the clamping surface 31 provided by the clamping member 30 of the present invention has an anti-slip effect, the present invention can be applied to gripping containers, beverage cans, beverage bottles, etc.; when the end of the clamping jaw 20 of the present invention is provided When the holding member 30 touches the beverage can 40, the holding surface 31 of the holding member 30 can deflect against the body of the beverage can 40 (as shown in FIG. 6); and when the present invention holds a smaller diameter When the beverage can 40A, the clamping member 30 can deflect the shaft 21 by a larger angle, so that the clamping surface 31 of the clamping member 30 can deflect against the body of the smaller diameter beverage can 40A (as shown in FIG. 7 Shown).

When the present invention clamps a beverage bottle 50 with an arc, the clamping member 30 provided at the end of the clamping claw 20 can deflect its clamping angle according to the curvature of the bottle body, so that the clamping surface 31 of the clamping member 30 can also abut At the body of beverage bottle 50 (as shown in Figure 8), you can smoothly grip this kind of curved beverage bottle; and if the neck of beverage bottle 50A is relatively long (such as marbles, beer, etc.) … Etc.), or due to factors such as the shape of the bottle body, so that the clamping member 30 cannot abut the bottle body or bottleneck of the beverage bottle 50A, the clamping member 30 will deflect with the shaft 21 as the fulcrum. When the holding member 30 leans against the bottle body, as the gripper rises, the clamping member 30 can be deflected by the curve of the clamping jaw 20 following the curve of the bottle body of the beverage bottle 50, and then when the top of the holding member 30 touches the bottle cap At 51, since the outer diameter of the bottle cap 51 is larger than the outer diameter of the bottle body, the top end of the clamping member 30 can abut against the lower edge of the bottle cap 51 (as shown in FIG. 9). The beverage bottle 50A is clamped and positioned, and can be raised and moved for players and buyers to obtain the beverage bottle 50A.

Therefore, as can be seen from the above, the present invention has the following advantages:

(1) Since the clamping member 30 of the present invention is pivotally coupled to the end of the clamping jaw 20 by using the shaft 21, it can rotate with the shaft 21 as a fulcrum, so that the clamping member 30 can follow the curve of the body of the container The curve is turned so that it can lean against the bottle body, which can provide a holding container and be dropped.

(2) Since the clamping member 30 of the present invention is provided with a slip-preventing surface 31, when the gripped container bottle (can) is relatively smooth, the container, bottle, and jar can also be used by the slip-preventing effect of the slip-preventing surface 31. It will not slip off and drop. In addition to ensuring that players and buyers can get the goods, it can also maintain the integrity of the product packaging.

(3) Since the clamping member 30 of the present invention is pivotally coupled to the end of the clamping jaw 20 by the shaft 21, it can be rotated by the shaft 21 as a fulcrum, which can not only be used to grab containers, bottles and cans with different outer diameters It can also be used to grab containers, bottles, and cans with different curves and arcs. Therefore, the present invention can indeed increase the practicality and range of use of the gripper.
