[0026] See also Figure 1 A coupler structure of a specific embodiment of the utility model is used to connect a screw-in structure 3 and a first connecting member 4. The coupler structure includes a first coupling block 1 and a second coupling block 2, and the first coupling block 1 and the second coupling block 2 are arranged in pairs at the connecting end of the screw-in structure 3 and the first connecting member 4, and the first coupling block 1 and the second coupling block 2 are locked via a fixed point. After locking, the first coupling block 1 and the second coupling block 2 can tightly hold the screw-in structure 3 and the first connecting member 4 to limit relative rotation between the two. At the same time, after the screw-in structure 3 and the first connecting member 4 are coupled via the coupler structure, the central axis of the screw-in structure 3 and the first connecting member 4 coincide with each other to ensure the coaxiality of the two after connection.

[0027] Specifically, see Figures 2 to 3 An embedding groove 6 is provided inside the opposite sides of the first coupling block 1 and the second coupling block 2, and the screw-in structure 3 and the connecting end of the first connecting member 4 are embedded in the embedding groove 6 at the same time. After the embedding is completed, the two are fixedly connected together by the locking member 5 to play a locking role for both at the same time. In order to enable the connecting ends of the screw-in structure 3 and the first connecting member 4 to be tightly connected after locking, axial end bevels 7 are provided at two ends of the connecting ends of the screw-in structure 3 and the first connecting member 4 that are far away from each other, and a matching bevel 61 is provided in the embedding groove 6. When the connecting ends of the screw-in structure 3 and the first connecting member 4 are both embedded in the embedding groove 6, the axial end bevels 7 provided on the screw-in structure 3 and the first connecting member 4 can abut against the matching bevel 61, that is, the screw-in structure 3 and the first connecting member 4 are matched at a non-horizontal angle, and the matching angle between the axial end bevels 7 and the matching bevel 61 respectively provided on the two is 1°~89°, so as to realize the mutual cooperation between the screw-in structure 3 and the first connecting member 4 in the embedding groove 6, thereby ensuring that the screw-in structure 3 and the first connecting member 4 can be stably connected and fixed.

[0028] More specifically, when the screw-in structure 3 is docked with the first connecting member 4, a first slot 81 is opened at the connecting end of the screw-in structure 3, and then a second slot 82 is opened at the connecting end of the first connecting member 4, and the first slot 81 and the second slot 82 are both semicircular. When the two are docked with each other, the first slot 81 and the second slot 82 are opposite to each other to form a locking hole 8, and the locking member 5 for locking the first coupling block 1 and the second coupling block 2 can be embedded in the locking hole 8, so as to simultaneously lock the first coupling block 1, the second coupling block 2, the first connecting member 4 and the screw-in structure 3.

[0029] The first coupling block 1 and the second coupling block 2 are both provided with fixing slots 9, and the fixing slots 9 are arranged corresponding to the locking holes 8, that is, the fixing slots 9 can be connected with the locking holes 8 formed by the screw-in structure 3 and the first connecting member 4. When the first coupling block 1 and the second coupling block 2 need to be locked, the first coupling block 1 and the second coupling block 2 can be connected with the screw-in structure 3 and the first connecting member 4 by passing the locking member 5 through the locking hole 8 and the fixing slots 9. In addition, the fixing slots 9 provided on the first coupling block 1 and the second coupling block 2 are set as threaded holes, and the locking member 5 can be a fixing bolt, which is screwed into the threaded holes provided on the first coupling block 1 and the second coupling block 2 in sequence, so that the two are fixedly connected.

[0030] In addition, a positioning hole 10 is provided on the first coupling block 1 and the second coupling block 2. The positioning hole 10 is arranged along the axial direction of the first connecting member 4 or the screw-in structure 3, and is on the same axis as the fixing slot 9 provided on the first coupling block 1 and the second coupling block 2. The positioning member is suitable for being embedded in the positioning hole 10, and the positioning hole 10 is also arranged as a threaded hole. After the positioning member is screwed into the positioning hole 10, the end of the positioning member does not contact the outer surface of the screw-in structure 3 and the first connecting member 4.

[0031] When the first coupling block 1 and the second coupling block 2 are connected to the screw-in structure 3 and the first connecting member 4 by the locking member 5, a gap 11 is formed between the first coupling block 1 and the second coupling block 2 after the connection is completed, and the gap 11 formed is arranged along the axial direction of the first connecting member 4 and the screw-in structure 3. Through the setting of the gap 11, when the embedding groove 6 opened on the inner wall of the first coupling block 1 and the second coupling block 2 is opposite to the screw-in structure 3 and the connecting end of the first connecting member 4, the first coupling block 1 and the second coupling block 2 can be as close to each other as possible to ensure that the matching bevel 61 opened in the embedding groove 6 can be in close contact with the axial end bevel 7 opened at the connecting end of the screw-in structure 3 and the first connecting member 4, and when the first coupling block 1 and the second coupling block 2 are locked, the gap between the two can be effectively compensated by the axial end bevel 7 and the matching bevel 61, so that the self-locking force corresponding to the locking torque can be applied at the same time, thereby ensuring that the first coupling block 1 and the second coupling block 2 can be tightly connected to the screw-in structure 3 and the first connecting member 4.

[0032] A continuous metering device in a specific implementation of the utility model adopts the coupler structure described in any of the above embodiments of the utility model. The continuous metering device includes a screw and a plunger push rod. The coupler structure can couple the screw and the plunger push rod so that the central axis of the screw and the plunger push rod coincide with each other, thereby ensuring the coaxiality of the two after the connection. At the same time, the plunger push rod and the screw will not rotate relative to each other after the coupling of the coupler structure, and the connection between the screw and the plunger push rod is tighter.
