The sliding rail 31 is a linear sliding rail and is arranged along the side edge of the rotating disc 1; the two clamping jaws 34 are respectively arranged on the two sliding blocks 32 so as to be capable of opening or clamping the penicillin bottles along the sliding rails 31; one end of the spring 33 is connected with one clamping jaw 34, and the other end of the spring is positioned on the side of the other clamping jaw 34 and fixedly connected with the rotating disc 1, so that the two clamping jaws 34 automatically maintain a clamping state. The spring 33 and the sliding rail 31 in each self-resetting paw are respectively positioned on two opposite sides of the rotating disc 1, and the position of the spring 33 is reasonably designed, so that the self-resetting paw is favorable for disassembly and replacement.
Further, each self-resetting claw further comprises a ratchet wheel 35, the ratchet wheels 35 are respectively connected with the two clamping jaws 34 to form a crank block mechanism, the linear motion of the two clamping jaws 34 along the sliding rail 31 can be converted into the rotary motion of the ratchet wheels 35, and tooth parts of the ratchet wheels 35 are clamping fit parts.

Specifically, as shown in fig. 10-12, two arc-shaped connecting rods 36 are arranged between the ratchet 35 and the two clamping jaws 34, one end of each connecting rod 36 is hinged with the corresponding clamping jaw 34, and the other end of each connecting rod is hinged with the ratchet 35 on the side of the other clamping jaw 34; the two connecting rods 36 are arranged symmetrically with respect to the center of the hinge point of the ratchet 35. The two connecting rods 36 are arranged opposite to each other; the connecting line between the two connecting rods 36 and the hinging point O, P of the corresponding clamping jaw 34 is consistent with the movement direction of the clamping jaw 34, and the connecting line between the two connecting rods 36 and the hinging point M, N of the ratchet wheel 35 is obliquely arranged, so that the structure is convenient and labor-saving to operate.
As shown in fig. 2-4, the thrust member 4 is rotatably disposed on the mounting base 6 through a hinge point, the clamping portion on the thrust member 4 is a pawl 41 for matching with the ratchet 35, the thrust member 4 is further provided with an abutting portion 42 for matching with the locking component 2, and the abutting portion 42 is a straight rod connected with the pawl 41 for sliding along the inner contour of the locking component 2.

The principle of how the ratchet mechanism and the two clamping jaws cooperate to realize synchronous sliding and different state switching in the present embodiment will be described with reference to two mutually-converted motion states of fig. 12 and 13. In this embodiment, the ratchet 35 only allows unidirectional counterclockwise rotation under the clamping engagement of the pawl 41, for the jaw assembly not contacting with the protrusion 22, when the jaw assembly is affected by external force in the process of rotating along with the rotating disc 1, and the two jaws 34 have a tendency to open to both sides, the connecting rod 36 correspondingly connected with the left jaw 34 has a tendency to move left, the hinging point M on the corresponding ratchet 35 has a tendency to move left, the connecting rod 36 connected with the right jaw 34 has a tendency to move right, the hinging point N on the corresponding ratchet 35 has a tendency to move right, the ratchet 35 has a torque that moves clockwise, but under the limit of the pawl 41, the ratchet 35 mechanism limits the opening movement of the two jaws 34, so as to lock the clamping state; if there is no detent 14 limit, the opening process is the one shown in fig. 12 to 13. Similarly, when the two jaws 34 have a tendency to fold inwardly, the ratchet 35 has a torque to move counterclockwise, and referring to the variation of fig. 13 to 13, the ratchet 35 allows a counterclockwise rotational movement even under the click of the click 41, thereby folding inwardly or increasing the clamping force for clamping the penicillin bottle.
As a specific embodiment, as shown in fig. 14, the clamping and conveying device is provided with two mounting bases 6, the two mounting bases 6 are arranged on the same rotary table 7, the two mounting bases 6 and the rotary table 7 are in an integrated structure, the rotary table 7 is arranged on a fixed base 8, the rotary table 7 performs circular motion relative to the fixed base 8, and the fixed base 8 is used for being arranged on a frame of a workbench.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
