When the article hooking mechanism hooks an article, the article pushes down the linkage elastic sheet 4, namely, the linkage elastic sheet 4 is in a pressed state and then is separated from the fixed sheet 21 downwards, the anti-falling device 2 descends under the action of gravity, when the movable sheet 22 descends to a position separated from the sliding channel 11, the first elastic piece 28 props up the movable sheet 22, the movable sheet 22 cooperates with the hook 3 to limit the article, and the article is prevented from being separated from the hook 3. Thus, errors can be reduced in an operating environment with low visibility, and damage to fragile products can be avoided.

As shown in fig. 3, the article hooking mechanism further includes a second elastic member 5, and the second elastic member 5 is abutted between the central shaft 23 and the central shaft 23 for supporting the central shaft 23 upward. In this way, the second elastic member 5 can provide an elastic force for returning the anti-falling device 2 upward. Specifically, the second elastic element 5 includes a return spring, the return spring is sleeved on the central shaft 23, a protruding portion 27 for abutting against the upper end of the return spring is arranged on the central shaft 23, and the protruding portion 27 may be a protruding ring with a diameter larger than that of the return spring, or may be a protruding block arranged on one side of the central shaft 23 and used for abutting against the upper end of the return spring. The inner wall of the movable channel of the holding rod 1 can be provided with a limiting part for limiting the lower end of the reset spring. So configured, when the central shaft 23 is displaced downwardly, the projection 27 will compress the return spring downwardly, which compresses against the projection 27 to exert an upward force on the central shaft 23, which force is greater than the downward force on the central shaft 23, such that the central shaft 23 automatically returns upwardly.

As shown in fig. 3 and 5, the moving block 25 includes a manipulating part 251 and a connecting part 252, the manipulating part 251 being located at the outer side of the grip lever 1 and having a width larger than that of the bar-shaped hole 12, the connecting part 252 passing through the bar-shaped hole 12 and connecting the central shaft 23 and the manipulating part 251. By this arrangement, the central shaft 23 can be reset upward by pushing the operating part 251 upward in the event of failure of automatic recovery, and the use requirement can be satisfied more flexibly in operation. The connection portion 252 may be detachably engaged with the central shaft 23, for example, by screwing or plugging.

As shown in fig. 1 and 3, the top wall of the grip lever 1 has an opening (not shown), the central shaft 23 is exposed upward from the opening, and a stop member 26 is provided at the top end of the central shaft 23, and the width of the stop member 26 is larger than the aperture of the opening. The stopper 26 serves to restrict the central shaft 23 from descending. It will be appreciated that the stop 26 and the operator 251 may both be provided or only one of them may be provided.

As shown in fig. 3 and 6, an inclined surface is provided at the lower end of the grip lever 1 at a side close to the connecting end 41 of the link elastic piece 4. The angle between the inclined surface and the length direction of the holding rod 1 is preferably 45 degrees. The lower end of the grip lever 1 is provided with an inclined surface to provide a sufficient swing space for the movable piece 22. The opening angle of the movable piece 22 with respect to the fixed piece 21 is preferably 90 degrees.

As shown in fig. 3, a reinforcing rib 31 is arranged between the holding rod 1 and the hook 3, the reinforcing rib 31 comprises a first connecting section and a second connecting section, the first connecting section is connected with one side of the holding rod 1, which is away from the inclined surface, and the second connecting section is connected with the wall surface of the hook 3, which is away from the opening of the hook 3. The reinforcing ribs 31 are arranged to be beneficial to increasing the connection strength between the holding rod 1 and the hook 3, enhancing the stability of the hook 3 and avoiding the occurrence of the condition of breakage or bending deformation of the hook 3 caused by hanging a heavy object.

As shown in fig. 1, 3 and 4, the cross section of the hook 3 and the cross section of the linkage elastic piece 4 are arc-shaped. The height of the tail end of the hook 3 is higher than or equal to the height of the hinge position of the movable plate 22 and the fixed plate. So arranged, the articles are easy to be placed and are separated from the hooks 3. The cross-section arc of the hook 3 is preferably 5/8 of an arc, i.e. the angle corresponding to the cross-section arc is 225 degrees. The connecting end 41 of the linkage elastic sheet 4 is connected with the wall surface of the hook 3 facing the fixed sheet 21, and the height of the connecting end 41 of the linkage elastic sheet 4 is lower than the height of the hinge position of the movable sheet 22 and the fixed sheet. By the arrangement, the article can be ensured to move a certain distance along the hook 3 and then touch the linkage elastic sheet 4, so that the article is further ensured not to fall off when being hooked.

The principle of use of the article hooking mechanism in this embodiment is as follows:

as shown in fig. 1 and 3, when the article hooking mechanism is in a normal state, i.e. the linkage elastic sheet 4 is in a non-pressed state, the movable end 42 of the linkage elastic sheet 4 abuts against the fixing sheet 21, at this time, the movable sheet 22 and the fixing sheet 21 are at least partially located in the movable channel, and the movable sheet 22 is in a closed state under the restriction of the movable channel.

As shown in fig. 5 and 6, when the hook 3 hooks an article, the article pushes down the linkage elastic sheet 4, that is, the linkage elastic sheet 4 is in a pressed state and then is separated from the fixing sheet 21 downward, and the anti-falling device 2 descends under the action of gravity. When the movable piece 22 descends to a position separating from the sliding channel 11, the elastic force of the first elastic piece 28 stretches the movable piece 22, the movable piece 22 swings upwards, namely the movable piece 22 is switched to an open state, the movable piece 22 cooperates with the hook 3 to limit articles, and the articles are prevented from separating from the end part of the hook 3. Thus, errors can be reduced in an operation environment with lower visibility, and damage to fragile products can be avoided, for example, the sample is safer and firmer when the sample is fished in a liquid nitrogen deep low-temperature environment. When the article transferring operation is finished, the linkage device can automatically reset upwards under the auxiliary action of the second elastic piece, and if the automatic reset fails, a user can also manually intervene in the reset, such as pushing the moving block 25 or the stopping piece 26 upwards, so that the central shaft 23 moves upwards relative to the holding rod 1. In this way, the use requirements can be met in an operation more flexibly.

Finally, it should be noted that: the foregoing description is only a preferred embodiment of the present utility model, and the present utility model is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present utility model has been described in detail with reference to the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
