The arc block 74 can be moved to be disposed in the sliding area 73. The arc block 74 has a semicircular shape and is made of a frictional material, such as rubber. The maximum diameter of the semicircular area of the circular arc block 74 is greater than the maximum diameter of the semicircular structure of the anchor type locking block 72.

In an embodiment of the present invention, as shown in FIGS. 1 and 2, the balance weight 80 is connected to the side of the lifting member 40 opposite to the gripping pawl 60. The balance weight 80 is used to balance the weight generated by the combination of the connecting beam 50 and the holding and taking claw 60, so as to prevent the connecting post 30 from being affected by the weight of the connecting beam 50 and the holding and taking claw 60 and tilting toward one side of the holding and taking claw 60.

In one embodiment of the present invention, the holding and taking device 1 is provided with a wireless module (not shown), whereby the holding and taking device 1 can be controlled by a remote computer (not shown) to enable the holding and taking device 1 Move along the track set 90 to the front of the specific outer box 300, and rotate the bottom rotating table 11 and the top rotating table 12, or move the lifting member 40 and the connecting beam 50, so that the gripping claw 60 is aligned with the specific inner side The hole 420 of the drawer 400. However, the wireless module and the remote computer control are conventional technologies, and they are not the focus of this case, so I won't repeat them.

As shown in Figures 1 to 4, in an embodiment of the present invention, when the user wants to use the holding device 1 to take out the specific inner drawer 400 from the specific outer box 300, the user can manipulate the remote computer To control the holding and taking device 1 to move along the track group 90 to the front of the specific outer box 300, and to rotate the bottom rotating table 11 and the top rotating table 12, and then to move the lifting member 40 and the connecting beam 50 to make the holding and taking claw 60 Align the hole 420 of the specific inner drawer 400. Then, the user can remotely manipulate the gripping claw 60 to move on the connecting beam 50 along a first moving direction A until the four gripping ends 62 respectively extend into the four holes 420.

Next, as shown in FIG. 5, when the gripping pawl 60 moves along a first moving direction A, the four gripping ends 62 will enter the four holes 420 respectively; and the gripping end 62 will enter along the first moving direction A. During the process of the hole 420, since the conical hole of the hole 420 has a slope, the horizontal movement of the holding end 62 will push the slope of the hole 420 and drive the inner drawer body 410 to fit the slope of the conical hole of the extraction hole 20 as a whole, and Raise upward along the ascending direction M. For example, in the dashed portion of the gripping claw 60 in FIG. 5, when the gripping end 62 has not been inserted into the hole 420, the entire inner drawer body 410 has not yet risen along the ascending direction M along the slope of the conical hole of the hole 420; However, when the holding end 620 moves along the first moving direction A and completely enters the extraction hole 20, the inner drawer body 410 as a whole rises along the ascending direction M along the slope of the conical hole of the extraction hole 20, so that the inner side The height of the drawer body 410 rises to be higher than the outer box stopper 320; in this way, the outer box stopper 320 cannot stop the raised inner drawer 400. It should be noted that, in order to clearly illustrate the process of the gripping claw 60 raising the inner drawer 400 in FIG. 5, the fastener 70 is not shown in FIG. 5.

As shown in Figures 7 and 8, when the gripping pawl 60 continues to move along the first moving direction A, the anchor-type locking block 72 will move until it touches the inclined surface 431; at this time, if the gripping pawl 60 moves along the When the first moving direction A continues to move, the anchor-type clamping block 72 will rise along the inclined surface 431 and drive the pivoting portion 71 to rotate. Finally, the anchor-type clamping block 72 will rise higher than the inclined surface 431.

Next, as shown in FIG. 9, if the gripping pawl 60 continues to move along the first moving direction A, the anchor-type clamping block 72 will cross the inclined surface 431 and sink into the handle 430. As a result, the anchor of the clamping member 70 The anchor type hook structure of the type locking block 72 can fasten the handle 430, and the four holding and taking ends 62 of the holding and taking claw 60 are also combined with the four holes 420, respectively. At this time, the user can manipulate the gripping pawl 60 to move along the second moving direction B on the connecting beam 50 to move the inner drawer 400 from the outside through the combination of the gripping pawl 60, the fastener 70 and the inner drawer 400 The box 300 is taken out, and the holding and picking device 1 is controlled to move to a specific location along the track group 90 for the user to obtain the inner drawer 400 and the contents therein.

In addition, as shown in Figures 2 and 4, if the user wants to use the holding and taking device 1 to put the inner drawer 400 into a specific outer box 300, the user can manipulate the remote computer to control the holding and taking device 1 to hold and take the inner drawer. 400 moves along the track group 90 to the front of the specific outer box 300, and rotates the bottom rotating table 11 and the top rotating table 12, and then moves the lifting member 40 and the connecting beam 50 so that the gripping pawl 60 can hold the inner drawer 400 , Align the specific outer box 300, and push the inner drawer 400 into the outer box 300.

Next, as shown in FIGS. 9 and 10, after the inner drawer 400 is completely pushed into the outer box 300, the user must release the clamp between the fastener 70 and the inner drawer 400 to allow the holding device 1 and the inner drawer 400 separation. Therefore, the user can control the gripping pawl 60 of the gripping device 1 to move along the first moving direction A, so that the arc block 74 moves until it touches the inclined surface 431 and rises along the inclined surface 431, and drives the pivoting portion 71 to rotate . The pivoting portion 71 that rotates will cause the anchor-type clamping block 72 to rise, thereby releasing the clamping between the anchor-type clamping block 72 and the handle 430.

Next, as shown in FIG. 11, when the arc block 74 touches the inclined surface 431, and the anchor-type clamping block 72 rises and the clamping between the handle 430 is released, if the gripping pawl 60 moves along the second moving direction The movement of B will drive the pivoting portion 71 and the anchor-type fixing block 72 to move along the second moving direction B, and the arc block 74 will still stay on the inclined surface 431 by its own frictional force. That is to say, the position of the arc block 74 will not change, but the pivoting portion 71 and the anchor type securing block 72 will be far from the handle 430 relative to the arc block 74; in addition, since the semicircular area of the arc block 74 is the largest The diameter is larger than the maximum diameter of the semi-circular structure of the anchor-type clamping block 72, so the semi-circular area of the arc block 74 that remains stationary can stably support the pivoting portion 71 and the anchor-type clamping block 72, as a result When the anchor-type securing block 72 is away from the handle 430, the anchor-type securing block 72 will not be stuck to the handle 430.

Finally, as shown in FIGS. 6 and 12, after the anchor-type fixing block 72 and the handle 430 are separated, the gripping pawl 60 can continue to move along the second moving direction B, and the gripping end 62 is allowed to move along the second movement direction. The direction B exits the hole 420. Since the conical hole of the hole 420 has a slope, the horizontal movement of the holding end 62 will drive the inner drawer main body 410 to fit the slope of the conical hole of the extraction hole 20 as a whole, and to lower down in the descending direction N to be lower than the outer box Halt block 320. In this way, the inner drawer 400 is completely inserted into the outer box 300, and the outer box stopper 320 can stop the inner drawer 400 to prevent the inner drawer 400 from being shaken and falling out of the outer box 300. It should be noted that, in order to clearly illustrate the process of lowering the inner drawer 400 by the holding and taking claw 60 in FIG. 6, the fastener 70 is not shown in FIG. 6.

With the design of the holding and taking device 1 of the present invention, the user can take out the inner drawer from the outer box or put it into the outer box by remote operation, and can also move the inner drawer to a specific location along the track, so that the user can easily To obtain the items in the inner drawer at a specific location, the user can save the labor cost and time of manually moving to the outer box to take out the inner drawer, so as to achieve the effect of automatic operation.

It should be noted that the above are only examples, and are not limited to the examples. For example, those that do not deviate from the basic structure of the present invention should be the scope of the rights claimed by this patent, and the scope of the patent application shall prevail.
