Among them, the frame body 30 may be specifically configured as two frames. The bottom end of the connector is fixedly provided with a beam 200, and the frame body 30 is two frames which are arranged on the beam 200 with adjustable distance, extend downwards from the beam 200 and bend towards the direction for clamping the vessel. The elastomer is installed between two frames, can make the centre gripping unit follow the shape and attach on the household utensils surface, improves centre gripping laminating degree, improves centre gripping stability and security promptly.

In the specific mechanism, a plurality of tension springs 311 arranged in parallel are connected between two side frames of the same clamping unit, and the tension springs 311 arranged in parallel form an elastic body together. As shown in fig. 1 and 6, the frame extends downwards from the top of the frame and is bent towards the vessel clamping direction to form an arc shape, when the clamping device operates, the elastic body can be attached to the vessel from bottom to top along with the shape, correspondingly positions and clamps the vessel, and improves the clamping stability; in addition, a plurality of hook holes 301 are arranged on the frame at intervals, correspondingly, tension springs 311 with the same number are arranged, the tension springs 311 are all hooked on the frame through the hook holes 301, and the tension springs 311 are coated with plastic layers 312 outside the tension springs 311, so that friction between the elastic body and the vessel can be improved, and clamping stability and safety are improved.

It should be noted that, as a preferred embodiment, the shape of the elastic body is as shown in fig. 1 and fig. 4, and the elastic body may be a strip or a plate, and it can clamp the vessel with the two clamping units and adhere to the surface of the vessel with the shape. Of course, the preferred embodiments of the elongated or plate-shaped elastic body described above can achieve good clamping effects. The rubber tube can be sleeved by the spring to form an elastic body, and the rubber tube can also be suitable for manufacturing an integral elastic body by using rubber or a rubber plate. Is mounted on the frame 30.

As shown in fig. 1 and 3, the connector includes a first connecting rod 21 and a second connecting rod 22 respectively disposed on the two clamping units, the first connecting rod 21 is fixedly connected to the left end of the operating unit 1, and the second connecting rod 22 is hinged to the right end of the operating unit 1; a driving rod 222 which is positioned below the operation unit 1 and can be hooked and held by fingers is fixedly arranged on the second connecting rod 22; the two clamping units can be closed by the finger hook to drive the driving rod 222 to approach the operation unit 1 and drive the second connecting rod 22 to rotate. In order to improve the grip feeling of the fingers, as a preferred embodiment, as shown in fig. 2 and 3, the grasping side 101 of the operation unit 1 is provided with a circular arc chamfer, the finger grip side 102 is provided with a receiving groove 100 for receiving the driving rod 222 therein; the finger-grip side 102 may be configured with wave-shaped protrusions 103 on one side.

Specifically, as shown in fig. 1 and 2, a spreading spring 105 is disposed between the second connecting rod 22 and the operating unit 1 for driving the second connecting rod 22 to rotate in a direction away from the first connecting rod 21. Wherein, the spreading spring 105 can use a torsion spring and is sleeved on the hinge shaft 104 between the second connecting rod 22 and the operation unit 1, so that the two clamping units can be kept in an open state in a non-operation state, and the subsequent use is facilitated.

In addition, the two side frames of the same clamping unit are arranged on the cross beam 200 in a manner that the distance between the two side frames is adjustable. As shown in fig. 5 and 7, the cross beam 200 is provided with a sliding groove 201, and the frame is provided with a sliding block 320 capable of sliding in the sliding groove 201; a locking member 202 is disposed between the frame and the connecting body to lock the frame in the sliding position. When the frame is adjusted to the required position, the frame can be locked, the frame is prevented from sliding again, and the stability of the clamping unit is improved.

Based on the design idea of adjustable space between two frames, as shown in fig. 5 and 7, in this embodiment, a rack 322 located above the cross beam 200, and a kneading widening rod 323 and a kneading narrowing rod 324 configured on the rack 322 are fixedly arranged on the frame; the bottom of the connecting body is sleeved with a rotatable central gear 321, a rack 322 is meshed with the central gear 321, a kneading widening rod 323 is positioned at one end of the rack 322 far away from the frame, and a kneading narrowing rod 324 is arranged near the middle of the rack 322. When the pinching narrowing bars 324 on the two frames of the same clamping unit are pinched, the two pinching narrowing bars 324 move close to the connecting body, and the two racks 322 move inwards synchronously due to the pinching of the central gear 321, so as to drive the two frames to close. The above is the narrowing and narrowing process of the two frames. In addition, the rack 322 is over the connecting body in length, and when the kneading widening bar 323 at the end part is kneaded, the two racks 322 move outward synchronously, thereby driving the two frames to be far away. The above is a two-frame widening process. The locking member 202 may be a locking nut screwed on the connecting body and capable of locking the central gear 321, so as to lock the position of the frame and ensure the stability of the clamping unit.

When the utensil gripper in this embodiment is used, the operating unit 1 is gripped by the palm, the gripping units are opened by the spreading spring 105, the driving rod 222 is gripped by the finger hook, the driving rod 222 is received in the receiving slot 100, the two gripping units approach each other and grip the utensil until the elastic body clings to the surface of the utensil, and then the utensil moving operation is completed. On the contrary, when the vessel is moved, the fingers are released, the driving rod 222 is ejected out of the containing groove 100 under the action of the unfolding spring 105, and the two clamping units are restored to the unfolded state.

The vessel holder described in this embodiment can achieve the purpose of adjusting the holding range by arranging the frame pitch on the cross beam 200 in an adjustable manner, thereby improving the practicability of the vessel holder. In addition, the elastic body can enable the clamping unit to be attached to the surface of the vessel along with the shape, so that the clamping attaching degree is improved, namely the clamping stability and the clamping safety are improved.
