[0037] The finger mechanism 200 comprises a mounting frame 210, a piston cylinder 220, a connecting rod assembly 230 and a knuckle assembly 240, wherein the mounting frame 210 is detachably connected to the finger plate 100 through a screw rod 300. Since the piston cylinder 220, the connecting rod assembly 230 and the knuckle assembly 240 are mounted on the mounting frame 210, when the mounting frame 210 is fixed on or separated from the finger plate 100, the piston cylinder 220, the connecting rod assembly 230 and the knuckle assembly 240 can be simultaneously fixed on or separated from the finger plate 100.

[0038] In the embodiment, the mounting frame 210 comprises a main body 211 and a mounting block 212 rotatably connected, and a matching block 213 detachably connected to the main body 211. The main body 211 is provided with a through hole 2111 for rotatably connecting the mounting block 212, a mounting plate 2112 for detachably mounting the piston cylinder 220, a mounting hole 2113 for detachably mounting the matching block 213, a first arc-shaped plate 2114 for rotatably cooperating with the clamping seat 120, a first connecting shaft 2115 and a second connecting shaft 2116 for respectively rotatably connecting the connecting rod assembly 230 and the knuckle assembly 240. In other embodiments of the utility model, the mounting frame 210 can only comprise the main body 211 and the mounting block 212, at this time, the mounting hole 2113 can not be provided on the main body 211.

[0039] It can be understood that the inner wall of the through hole 2111 is provided with a step 2117, and the inner wall of the through hole 2111 is rotatably connected to the mounting block 212 through the step 2117. That is, the through hole 2111 is slidably connected to the mounting block 212, so that the main body 211 can rotate relative to the mounting block 212, and at the same time, the mounting block 212 cannot move downward under the limiting action of the step 2117. The two mounting plates 2112 are oppositely arranged on both sides of the main body 211, and the opposite sides of the two mounting plates 2112 are respectively provided with a connecting block 2118, and the piston cylinder 220 is detachably inserted into the connecting block 2118, so that the piston cylinder 220 can be accommodated in the accommodation cavity between the two mounting plates 2112. The first arc-shaped plate 2114 is provided with a concave surface 2119, and any groove in the concave surface 2119 can be matched with the limiting block 124 during the rotation of the first arc-shaped plate 2114.

The outer wall of one end of the mounting block 212 is also concave to form a notch 2123, so that the one end of the mounting block 212 forms a non-circular structure which is matched with the shape of the card slot 122, thereby enabling the mounting block 212 to be inserted and fixed on the card seat 120 and unable to rotate under force. The second connecting hole 2121 of the mounting block 212 is formed with a protrusion 2124 which can be detachably abutted against the screw rod 300, so as to lock or release the screw rod 300.

[0041] The matching block 213 can be inserted and matched on the mounting hole 2113, so that the matching block 213 is detachably connected to the main body 211. The matching block 213 is provided with a second arc-shaped plate 2131 which is rotatably matched with the card seat 120, and the second arc-shaped plate 2131 can be enclosed with the first arc-shaped plate 2114 to form a mounting groove for accommodating the card seat 120, thereby preventing the card seat 120 from being exposed and affecting the appearance. Meanwhile, the mounting groove can also protect the card seat 120 from being damaged by external force to a certain extent. Moreover, the arrangement of the matching block 213 can reduce the difficulty of injection molding of the mounting frame 210 and save production cost. It can be understood that the second arc-shaped plate 2131 is also provided with a concave surface 2119 corresponding to the other limiting block 124, so as to also play a role in rotational positioning. In other embodiments of the present application, if the card seat 120 is provided with only one movable plate 123, the second arc-shaped plate 2131 can not be provided with the concave surface 2119, or the mounting frame 210 can not be provided with the matching block 213.

[0042] The piston cylinder 220 includes a piston rod 221 and a U-shaped buckle 222, wherein the piston rod 221 can perform reciprocating extension and contraction under the drive of hydraulic pressure (or air pressure). The U-shaped buckle 222 is arranged at the end of the piston cylinder 222, and the U-shaped buckle is detachably inserted on the connecting block 2118, for detachably fixing and connecting the piston cylinder 220 between the two mounting plates 2112.

[0043] The connecting rod assembly 230 is rotatably connected to the main body 211 through the first connecting shaft 2115, and the knuckle assembly 240 is rotatably connected to the main body 211 through the second connecting shaft 2116.

[0045] It can be understood that when the piston cylinder 220 is started, the piston rod 221 performs a telescopic motion. If the piston rod 221 extends out of the piston cylinder 220, it will drive the first knuckle 241 to rotate on the second connecting shaft 2116, at this time, the first link 231 and the second link 242 are connected and rotated to drive the second knuckle 242 to rotate on the first knuckle 241, and the third knuckle 243 to rotate on the second knuckle 242, thereby performing the bending action of the finger. If the piston rod 221 extends into the piston cylinder 220, it will drive the first knuckle 241 to rotate in the opposite direction on the second connecting shaft 2116, at this time, the first link 231 and the second link 242 are connected and rotated to drive the second knuckle 242 to rotate in the opposite direction on the first knuckle 241, and the third knuckle 243 to rotate in the opposite direction on the second knuckle 242, thereby performing the straightening action of the finger.

Specifically, the end of the screwing rod 300 provided with the clamping block 320 can pass through the first connecting hole 110 and the second connecting hole 2121, and then the screwing rod 300 is rotated, so that the clamping block 320 is rotated to abut the protrusions 2124, so as to clamp the screwing rod 300 on the hole wall of the second connecting hole 2121, and then the connecting block 212 can be fastened on the finger plate 100, so as to achieve the purpose of fixing and connecting the finger mechanism 200 to the finger plate 100. If the screwing rod 300 is reversed, the clamping block 330 is separated from the protrusions 2124 in the second connecting hole 2121, and then the screwing rod 300 is pulled out, the finger mechanism 200 can be separated from the finger plate 100 by pulling the finger mechanism 200. The above-mentioned arrangement can quickly realize the disassembly and assembly between the finger mechanism 200 and the finger plate 100, and the disassembly and assembly process is simple and convenient. In other embodiments of the utility model, the screwing rod 300 can be provided with an outer screw, and the inner wall of the first connecting hole 110 and the second connecting hole 2121 is provided with an inner screw matched with the outer screw, and by aligning the screwing rod 300 with the first connecting hole 110 and the second connecting hole 2121, and then rotating the screwing rod 300, the screwing rod 300 can be rotated to fasten or loosen the connecting block 212 on the finger plate 100.
