[0016] Advantages of the present utility model:
[0017] On the one hand, the present utility model provides a locking mechanism. By providing a mounting member, a locking member, and an actuating member slidably connected to the locking member, and at the same time providing an elastic member to connect the actuating member and the mounting member. In addition, in the present application, an oblong hole having an included angle with both the first direction and the second direction is provided on one of the locking member and the actuating member, and a limiting pin slidably connected to the oblong hole is provided on the other. Through the above settings, when unlocking is required, the operator only needs to use one hand to pull the actuating member in a direction away from the elastic member. During the movement of the actuating member, it overcomes the pulling force of the elastic member. By the cooperation of the limiting pin and the oblong hole, while the actuating member moves in a direction away from the elastic member, it can drive the locking member to move in a direction away from the mounting member, so that the locking member can slide out of the limiting hole on the tooling rack to unlock; when relocking is required, the operator only needs to release the hand pulling the actuating member. Under the pulling force of the elastic member, the actuating member moves in a direction close to the elastic member. By the cooperation of the limiting pin and the oblong hole, while the actuating member moves in a direction close to the elastic member, it can drive the locking member to move in a direction close to the mounting member, so that the locking member can be reinserted into the limiting hole on the tooling rack to achieve locking. During the above unlocking and relocking processes, the operator only needs to use one hand to complete the control of the locking mechanism, which is convenient to operate. At the same time, the locking member can automatically slide out of or be inserted into the limiting hole without manual extra pulling or inserting actions, reducing the operation steps and improving the work efficiency.
[0018] On the other hand, the present utility model provides a flipping tooling. The flipping tooling has all the features of the above locking mechanism, and its beneficial effects are the same as those of the above locking mechanism, which will not be elaborated here. In addition, by using the above locking mechanism, the flipping tooling can freely adjust the angle of the workpiece fixing member according to the actual processing requirements, so that the workpiece fixing member can be in different working positions. When machining different angular positions of the same workpiece, there is no need to disassemble the workpiece and then place the workpiece on another workpiece fixing member, reducing the operation steps in the machining process and improving the machining efficiency.

It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0029] Figure 1 Schematically shows the structure of a flipping tooling. It can be understood that Figure 1 the structure of the flipping tooling shown in Figure 1 does not constitute a limitation on the actual structure of the flipping tooling, and the flipping tooling may include more components than
[0030] such as Figure 1As shown in the figure, the flipping tooling includes a tooling rack 9, a flipping shaft 10, a workpiece fixing member 12, and a locking mechanism 100. The flipping shaft 10 is rotatably connected to the tooling rack 9. The locking mechanism 100 includes a mounting member 1 and a locking member 3. The workpiece fixing member 12 and the mounting member 1 of the locking mechanism 100 are both fixedly arranged on the flipping shaft 10. A limiting hole 921 is formed on the tooling rack 9, and the locking member 3 of the locking mechanism 100 can be inserted into the limiting hole 921. The tooling rack 9 has a bottom plate 91 and two support plates 92, and both ends of the flipping shaft 10 are rotatably connected to the two support plates 92 respectively. As Figure 2 shown, at least two limiting holes 921 are formed on the support plate 92, and the locking member 3 of the locking mechanism 100 can be alternatively inserted into the limiting holes 921. In this way, when the flipping tooling is flipped to a working position corresponding to different limiting holes 921, the locking mechanism 100 can lock the working position of the flipping tooling.
[0031] The structure of the above flipping tooling will be specifically described below.
[0032] Combined with Figure 1 and Figure 2 shown, the bottom plate 91 of the above tooling rack 9 and the two support plates 92 are both plate-shaped, and the cross-sectional shapes of the bottom plate 91 and the support plates 92 are, for example, rectangular. The two support plates 92 are respectively arranged on opposite sides of the bottom plate 91, and the above flipping shaft 10 can be rotatably connected to the two support plates 92 simultaneously.
[0033] The above flipping shaft 10 has a rod-shaped structure. The cross-sectional shape of the shaft body 101 (the middle part of the flipping shaft 10) of the flipping shaft 10 is, for example, rectangular or circular, and the cross-sectional shape of the connecting end 102 (the end of the flipping shaft 10) of the flipping shaft 10 is, for example, circular, where the cross-sectional direction is perpendicular to the axis of the shaft body 101. The two connecting ends 102 of the flipping shaft 10 are respectively rotatably connected to the corresponding support plates 92, and the shaft body 101 of the flipping shaft 10 is located between the two support plates 92. The way of rotatably connecting the connecting end 102 and the support plate 92 here is, for example: a through hole is formed on the support plate 92, the connecting end 102 is inserted into the through hole, and the center line of the through hole is coaxially arranged with the axis of the connecting end 102; a bearing is arranged between the outer surface of the connecting end 102 and the inner side wall of the through hole, so that the connecting end 102 can be rotatably connected to the support plate 92.
[0034] As Figure 1 shown, the workpiece fixing member 12 is arranged on the flipping shaft 10. Specifically, the workpiece fixing member 12 has a plate-shaped structure, and the shape of the workpiece fixing member 12 can be set according to the actual application scenario, for example, rectangular, oval, or "convex" shaped. The workpiece fixing member 12 is arranged on the shaft body 101 of the flipping shaft 10. The connection way between the workpiece fixing member 12 and the shaft body 101 is, for example, welding, connection by bolts, or connection by other connecting members.
[0035] The mounting member 1 of the locking mechanism 100 is also arranged on the turning shaft 10. Specifically, as Figure 1 , Figure 2 shown, the mounting member 1 is arranged on the connecting end 102 of the turning shaft 10. The mounting member 1 is arranged on the side of the support plate 92 away from the workpiece fixing member 12. The connection mode between the mounting member 1 and the connecting end 102 is, for example: through holes or blind holes are formed in the mounting member 1, and the opening direction of the through holes or blind holes faces the support plate 92, and the connecting end 102 passes through the support plate 92 and is inserted into the through holes or blind holes in the mounting member 1. When the opening shape of the through hole or blind hole is circular, the connecting end 102 and the through hole or blind hole are connected together by interference fit or welding; when the opening shape of the through hole or blind hole is non-circular (such as rectangular or triangular), the cross-sectional shape of the part of the connecting end 102 inserted into the through hole or blind hole can be set to be the same as the opening shape of the through hole or blind hole (here the cross-sectional direction is perpendicular to the axis of the connecting end 102), so that the connecting end 102 and the through hole or blind hole can be directly connected together by plugging, or can also be connected together by interference fit or welding.
[0036] As Figure 2 shown, at least two limiting holes 921 are formed in the above-mentioned support plate 92, and the locking member 3 of the locking mechanism 100 can be selectively inserted into the limiting holes 921. Specifically, at least two limiting holes 921 are formed in the side wall of the support plate 92 away from the workpiece fixing member 12. On the side of the support plate 92 away from the workpiece fixing member 12, the distance between the axis of the limiting hole 921 and the axis of the turning shaft 10 is a fixed value. In other words, on the side of the support plate 92 away from the workpiece fixing member 12, taking the position of the axis of the turning shaft 10 as the center of a circle and taking a fixed value as the radius to draw a reference circle on this side, the axes of the limiting holes 921 all fall on the circumference of this reference circle. The above-mentioned fixed value is: the numerical value of the shortest distance between the centroid of the locking member 3 of the locking mechanism 100 and the axis of the through hole or blind hole on the mounting member 1.
[0037] In the above solution of directly forming the limiting hole 921 in the support plate 92, the processing steps are few and the processing is simple. Of course, other solutions can also be used to set the limiting hole 921 in the support plate 92. For example, a groove is first formed in the support plate 92, and then a mounting block with the limiting hole 921 formed therein is arranged in the groove. The mounting block and the groove are detachably connected (for example, connected by bolts or pins). In this way, when the inner side wall of the limiting hole 921 is worn after multiple fits with the locking member 3, resulting in a reduction in the limiting accuracy, the entire mounting block can be removed from the support plate 92, and a non-worn mounting block with the limiting hole 921 can be re-arranged in the groove of the support plate 92, which is convenient for maintenance and repair and reduces the material cost during maintenance.
[0038] For a turnover tooling provided by the present utility model, when it is necessary to fix the working position of the workpiece fixing member 12, the angle of the workpiece fixing member 12 arranged on the turnover shaft 10 can be adjusted by rotating the turnover shaft 10 first, so that the workpiece fixing member 12 is in a suitable working position. Subsequently, the locking member 3 in the locking mechanism 100 is inserted into the limiting hole 921 corresponding to this working position on the support plate 92 to lock the working position of the workpiece fixing member 12; when it is necessary to change the working position of the workpiece fixing member 12, the locking mechanism 100 can be controlled first to make the locking member 3 of the locking mechanism 100 slide out of the limiting hole 921 on the support plate 92 to unlock the working position of the workpiece fixing member 12. Then, taking the axis of the turnover shaft 10 as the rotation axis, the locking mechanism 100 is rotated to drive the turnover shaft 10 to rotate, thereby changing the angle of the workpiece fixing member 12, so that the workpiece fixing member 12 is turned to another working position. Finally, the working position of the workpiece fixing member 12 is locked by using the locking mechanism 100. Through the above settings, the turnover tooling can freely adjust the angle of the workpiece fixing member 12 according to actual processing requirements, so that the workpiece fixing member 12 can be in different working positions. When machining different angular positions of the same workpiece, there is no need to disassemble the workpiece and then place the workpiece on another workpiece fixing member 12, which reduces the operation steps and improves the processing efficiency.
[0039] As can be seen from the above description, in the above turnover tooling, the locking mechanism 100 is the key mechanism for locking or unlocking the working position of the workpiece fixing member 12. Next, the specific structure of the locking mechanism 100 will be described in detail.
[0040] As Figure 3 shown, the above locking mechanism 100 includes a mounting member 1, a locking member 3, an actuating member 4, and an elastic member 5. Combining Figure 2 、 Figure 3, the locking member 3 is slidably connected to the mounting member along the first direction X1 and has a locking position and an unlocking position. When the locking member 3 is in the locking position, it can be inserted into the limiting hole 921 on the tooling rack 9. When the locking member is in the unlocking position, the locking member is separated from the limiting hole. It can be understood that the locking member 3 can pass through the mounting member 1 and then can be inserted into the limiting hole 921 on the above-mentioned tooling rack 9 to achieve the locking action. The way for the locking member 3 to pass through the mounting member 1 is, for example: a first through hole 11 adapted to the locking member 3 is provided on the mounting member 1, and the locking member 3 can pass through the first through hole 11. The actuating member 4 is slidably connected to the mounting member 1 along the second direction X2. An elastic member 5 is provided between the actuating member 4 and the mounting member 1. The elastic member 5 can always make the locking member 3 tend to move towards the locking position. As Figure 4 shown, a kidney-shaped hole 41 is provided on one of the locking member 3 and the actuating member 4, and a limiting pin 31 is provided along the third direction X3 on the other; the limiting pin 31 is slidably connected to the kidney-shaped hole 41, and the kidney-shaped hole 41 is arranged at an angle with both the first direction X1 and the second direction X2; combined with Figure 2 , Figure 4 , Figure 5 , it can be understood that when the actuating member 4 moves, it can make the locking member 3 slide out of or into the limiting hole 921, that is, when the actuating member 4 moves in the second direction X2, it can drive the locking member 3 to move in the first direction X1.
[0041] A locking mechanism 100 provided by the utility model includes an installation member 1, a locking member 3, an operating member 4 slidably connected to the locking member 3, and an elastic member 5 connecting the operating member 4 to the installation member 1. In addition, in this application, an oblong hole 41 having an included angle with both the first direction X1 and the second direction X2 is provided on one of the locking member 3 and the operating member 4, and a limit pin 31 slidably connected to the oblong hole 41 is provided on the other. Through the above settings, when unlocking is required, the operator only needs to use one hand to pull the operating member 4 in a direction away from the elastic member 5. During the movement of the operating member 4, the pulling force of the elastic member 5 is overcome. By the cooperation of the limit pin 31 and the oblong hole, while the operating member 4 moves in a direction away from the elastic member 5, it can drive the locking member 3 to move in a direction away from the installation member 1, so that the locking member 3 can slide out of the limit hole 921 on the tooling rack 9 to unlock; when relocking is required, the operator only needs to release the hand pulling the operating member 4. Under the pulling force of the elastic member 5, the operating member 4 moves in a direction close to the elastic member 5. By the cooperation of the limit pin 31 and the oblong hole, while the operating member 4 moves in a direction close to the elastic member 5, it can drive the locking member 3 to move in a direction close to the installation member 1, so that the locking member 3 can be reinserted into the limit hole 921 on the tooling rack 9 to achieve locking. During the above unlocking and relocking processes, the operator only needs to use one hand to control the locking mechanism 100, which is convenient to operate. At the same time, the locking member 3 can automatically slide out of or be inserted into the limit hole 921 without manual extra pulling or inserting actions, reducing the operation steps and improving the work efficiency.
[0042] Specifically, as Figure 3 shown, the installation member 1 has a plate-like structure or a rod-like structure, and a first through hole 11 is provided on the installation member 1. The cross-sectional shape of the installation member 1 is, for example, rectangular, circular, or oval, and the cross-sectional direction is perpendicular to the axis of the installation member 1 here.
[0043] The above locking mechanism 100 further includes a limit block 2. The limit block 2 has a cubic structure and is fixedly provided on the installation member 1. The connection manner between the limit block 2 and the installation member 1 is, for example, bolt connection or welding here.
[0044] The locking member 3 is slidably connected to the limiting block 2 along the first direction X1, and the limiting block 2 can limit the movement of the locking member 3 in the second direction X2. The first direction X1 is parallel to the center line of the first through hole 11, and the second direction X2 is perpendicular to the first direction X1. The way the locking member 3 is slidably connected to the limiting block 2 here is, for example: a locking chute (such as a dovetail chute or a T-shaped chute) is provided on the side wall of the locking member 3 close to the limiting block 2, the locking chute extends along the first direction X1, and a limiting slider is correspondingly provided on the side wall of the limiting block 2 close to the locking member 3. The locking member 3 and the limiting block 2 are slidably connected through the cooperation of the locking chute and the limiting slider. Of course, according to actual needs, a limiting chute can also be provided on the limiting block 2, and a corresponding locking slider can be provided on the locking member 3, and no more description will be given here.
[0045] In some embodiments, as Figure 3 shown, the number of the above-mentioned limiting blocks 2 is two, and the two limiting blocks 2 are respectively arranged on both sides of the locking member 3 along the second direction X2, and are both slidably connected to the locking member 3. Specifically, chutes or sliders are respectively provided on the two side walls of the locking member 3 close to the two limiting blocks 2, and sliders or chutes are correspondingly provided on the side wall of each limiting block 2 close to the locking member 3. The locking member 3 and the two limiting blocks 2 are slidably connected through the cooperation of the chutes and the sliders. By providing two limiting blocks 2 slidably connected to the locking member 3, the connection between the locking member 3 and the limiting block 2 can be made more firm, and the sliding process of the locking member 3 along the first direction X1 can be made more stable. It can be understood that since the limiting blocks 2 are provided on both sides of the locking member 3, the locking member 3 and the two limiting blocks 2 can also be slidably connected by only contacting. The sliding connection is achieved by only contacting, and the structure is simple, which is convenient for processing, installation, and maintenance.
[0046] As Figure 4 shown, the above-mentioned actuating member 4 is connected to the mounting member 1 through an elastic member 5, and the actuating member 4 is slidably connected to the locking member 3 along the second direction X2. The locking member 3 can be a whole cubic structure or a structure composed of multiple components. Combining Figure 2 、 Figure 4 , when the locking member 3 is composed of multiple components, the locking member 3 includes a sliding portion 32 slidably connected to the limiting block 2 and a plug pin 33 that can be inserted into the limiting hole 921; a chute 321 is provided in the sliding portion 32 along the second direction X2, and the actuating member 4 is slidably connected in the chute 321; a kidney-shaped hole 41 is provided on one of the sliding portion 32 and the actuating member 4, and a limiting pin 31 is provided on the other along the third direction X3, where the third direction X3 is perpendicular to the first direction X1 and the second direction X2 respectively.
[0047] Specifically, as Figure 3As shown, the above-mentioned moving member 4 has a long strip plate structure or a rod structure. The elastic member 5 is, for example, a spring or a flat rubber band. One end of the elastic member 5 is connected to one end of the moving member 4 to form a first connection portion 51, and the other end of the elastic member 5 is connected to one end of the mounting member 1. When the operator pulls the moving member 4 in a direction away from the elastic member 5 to change the position of the moving member 4, the elastic member 5 deforms; when the operator stops pulling the moving member 4 and releases the moving member 4, the elastic member 5 resets, and the moving member 4 can move in the direction where the elastic member 5 is located until the moving member 4 resets.
[0048] Combined with Figure 2 、 Figure 3 As shown, the sliding portion 32 of the locking member 3 has a cubic structure, and the bolt 33 also has a cubic structure or a cylindrical structure. The bolt 33 is provided on a side wall of the sliding portion 32 close to the above-mentioned mounting member 1. The centroid of the bolt 33 is located on the axis of the limiting hole 921 on the above-mentioned support frame, and the opening shape of the limiting hole 921 is adapted to the shape of the bolt 33, so that the bolt 33 can be smoothly inserted into the limiting hole 921. A sliding groove 321 is formed on the sliding portion 32, and the extending direction of the sliding groove 321 is parallel to the second direction X2. The moving member 4 can be slidably connected to the sliding groove 321. It is not difficult to understand that in order to slidably connect the moving member 4 with the sliding groove 321 on the sliding portion 32, corresponding through holes are also formed on the limiting block 2, so that the moving member 4 can pass through the limiting block 2 to achieve a sliding connection with the sliding groove 321 on the sliding portion 32. After the moving member 4 passes through the limiting block 2, the cooperation between the moving member 4 and the sliding groove 321 on the sliding portion 32 can limit the movement of the locking member 3 in the third direction X3.
[0049] As Figure 4 、 Figure 5 shown, a waist-shaped hole 41 is provided on the moving member 4. The waist-shaped hole 41 is arranged at an angle with both the first direction X1 and the second direction X2. A limiting pin 31 is arranged on the sliding portion 32 along the third direction X3. The limiting pin 31 is slidably connected to the waist-shaped hole 41. The movement of the moving member 4 can cause the locking member 3 to slide out of the limiting hole 921. Specifically, the waist-shaped hole 41 is obliquely arranged on the moving member 4. The waist-shaped hole 41 has a first end 411 close to the above-mentioned bolt 33 and a second end 412 far from the above-mentioned bolt 33. And the distance between the first end 411 of the waist-shaped hole 41 and the above-mentioned first connection portion 51 is greater than the distance between the second end 412 of the waist-shaped hole 41 and the above-mentioned first connection portion 51. When the moving member 4 is in a static state (not pulled), the limiting pin 31 passes through the first end 411 of the waist-shaped hole 41 along the third direction X3.
[0050] Combined with Figure 2 、 Figure 4, when the operator pulls the actuating member 4 in a direction away from the elastic member 5, the waist-shaped hole 41 on the actuating member 4 will move synchronously in a direction away from the elastic member 5, and the limit pin 31 slidably connected to the waist-shaped hole 41 slides from the first end 411 to the second end 412 of the waist-shaped hole 41. Since the waist-shaped hole 41 is inclined, during the process of the waist-shaped hole 41 moving away from the elastic member 5, the force exerted on the limit pin 31 by the inner side wall of the waist-shaped hole 41 can be decomposed into a force pointing away from the elastic member 5 and a force pointing away from the mounting member 1. At this time, since both the locking member 3 and the limit pin 31 provided on the locking member 3 are restricted by the limiting block 2 and cannot move in the direction away from the elastic member 5 (in the second direction X2), but the locking member 3 is not restricted in the first direction X1, so the locking member 3 can move away from the mounting member 1 under the action of the force pointing away from the mounting member 1, and then the bolt 33 of the locking member 3 automatically slides out of the limit hole 921. Combined with Figure 2 , Figure 5 , after the operator stops pulling the actuating member 4 and releases the actuating member 4, under the pulling force of the elastic member 5, the actuating member 4 moves in a direction close to the elastic member 5, and the limit pin 31 slidably connected to the waist-shaped hole 41 slides from the second end 412 to the first end 411 of the waist-shaped hole 41. Similarly, since the waist-shaped hole 41 is inclined, during the process of the waist-shaped hole 41 moving close to the elastic member 5, the force exerted on the limit pin 31 by the inner side wall of the waist-shaped hole 41 can be decomposed into a force pointing close to the elastic member 5 and a force pointing close to the mounting member 1. At this time, since both the locking member 3 and the limit pin 31 provided on the locking member 3 are restricted by the limiting block 2 and cannot move in the direction close to the elastic member 5 (in the second direction X2), but the locking member 3 is not restricted in the first direction X1, so the locking member 3 can move close to the mounting member 1 under the action of the force pointing close to the mounting member 1, and then the bolt 33 of the locking member 3 automatically inserts into the limit hole 921.
[0051] Of course, according to actual needs, the positions of the waist-shaped hole 41 and the limit pin 31 can also be interchanged, that is, a waist-shaped hole 41 is provided on the sliding portion 32 of the locking member 3, and a limit pin 31 is provided on the actuating member 4. However, the basic concept of using the reverse movement of the actuating member 4 away from or close to the elastic member 5 to drive the locking member 3 to move away from or close to the mounting member 1, and then drive the bolt 33 to slide out of or insert into the limit hole 921 is the same as above, and will not be described in detail here.
[0052] In some embodiments, such as Figure 2As shown, the locking mechanism 100 further includes a movable handle 6, which is disposed on the actuating member 4, for example, the movable handle 6 is disposed at one end of the actuating member 4 away from the elastic member 5. Specifically, the movable handle 6 is a rod-shaped structure, and the cross-sectional shape of the movable handle 6 is, for example, rectangular, circular or elliptical, etc., where the cross-sectional direction is perpendicular to the axis of the movable handle 6. One end of the movable handle 6 is connected to one end of the actuating member 4 away from the elastic member 5, and the other end of the movable handle 6 is away from the mounting member 1, and the movable handle 6 and the actuating member 4 are located on the same side of the mounting member 1. There is an angle between the axis of the movable handle 6 and the second direction X2, and the angle of the angle is, for example, 90°. When the movable handle 6 moves in the second direction X2, it can drive the actuating member 4 to move in the second direction X2.
[0053] In the above-mentioned locking mechanism 100, by providing a movable handle 6 at the end of the actuating member 4 away from the elastic member 5, after the operator's operating hand grasps the movable handle 6, the operator can lift the arm to pull the movable handle 6, thereby driving the actuating member 4 to move, providing a gripping position for the operator, enabling the operator to exert force better, and preventing the actuating member 4 from slipping out of the operator's hand when the operator pulls the actuating member 4, thereby improving the practicality of the locking mechanism 100.
[0054] In some embodiments, Figure 3 As shown, the locking mechanism 100 further includes a fixed handle 7, which is fixedly connected to the mounting member 1, and the fixed handle 7 and the movable handle 6 are located on the same side of the mounting member 1. Specifically, the fixed handle 7 is a rod-shaped structure, and the cross-sectional shape of the fixed handle 7 is, for example, rectangular, circular or elliptical, etc., where the cross-sectional direction is perpendicular to the axis of the fixed handle 7. One end of the fixed handle 7 is connected to one end of the mounting member 1. It is not difficult to understand that the fixed handle 7, the movable handle 6 and other components of the locking mechanism 100 described above are all installed on the same side of the mounting member 1. The axis of the fixed handle 7 is, for example, arranged parallel to the axis of the movable handle 6. In addition, in the second direction X2, the movable handle 6 is located between the fixed handle 7 and the first connecting portion 51.
[0055] In the above locking mechanism 100, by providing a fixed handle 7 on the mounting member 1, when the operator operates the locking mechanism 100, the operator can first place the palm of the operator's hand against the fixed handle 7, bend the thumb to hold the fixed handle 7, and then bend the remaining four fingers to pull the movable handle 6, thereby driving the action member 4 to move. In the above operation process, the operator only needs to use the fingers of the operator's hand to exert force to drive the action member 4 to move, without using the arm to exert force, the operation is simple and labor-saving, and the practicality of the locking mechanism 100 is further improved.
[0056] In addition, to ensure that when the operator pulls the movable handle 6 to drive the moving member 4 to move, the moving member 4 can smoothly drive the locking member 3 to achieve the unlocking function, there is a gap between the movable handle 6 and the fixed handle 7 in the second direction X2, and the size of this gap is greater than or equal to the length of the above-mentioned kidney-shaped hole 41 in the second direction X2. Through the above settings, it is possible to avoid interference between the movable handle 6 and the fixed handle 7, and further avoid the locking member 3 being unable to completely slide out of the limiting hole 921, ensuring that the unlocking function of the locking mechanism 100 can be realized normally.
[0057] In some embodiments, such as Figure 3 , Figure 4 , Figure 5 shown, an avoidance groove 71 is formed on one side of the fixed handle 7 close to the movable handle 6, and at least a part of the movable handle 6 can extend into the avoidance groove 71. Specifically, an avoidance groove 71 is formed on the fixed handle 7, and the opening direction of the avoidance groove 71 points to the direction where the movable handle 6 is located. In the second direction X2, the contour of the positive projection of the movable handle 6 is located within the contour of the positive projection of the avoidance groove 71, so that at least a part of the movable handle 6 can extend into the avoidance groove 71. At the same time, the depth dimension of the avoidance groove 71 in the second direction X2 is greater than or equal to the length of the above-mentioned kidney-shaped hole 41 in the second direction X2. Through the above settings, it is also possible to avoid interference between the movable handle 6 and the fixed handle 7, and further avoid the locking member 3 being unable to completely slide out of the limiting hole 921, ensuring that the unlocking function of the locking mechanism 100 can be realized normally; at the same time, it can also shorten the shortest distance between the axis of the movable handle 6 and the axis of the fixed handle 7, facilitating the operator to bend the four fingers to pull the movable handle 6, further improving the practicability of the locking mechanism 100.
[0058] In some embodiments, such as Figure 3 shown, the above-mentioned locking mechanism 100 further includes a fixed block 8 provided on the mounting member 1. The fixed block 8 is connected to the elastic member 5, and the elastic member 5 and the moving member 4 are arranged between the fixed block 8 and the fixed handle 7. In the second direction X2, the elastic force direction of the elastic member 5 and the moving direction of the moving member 4 are on the same straight line. Specifically, the fixed block 8 has a block structure or a rod structure, etc. The fixed block 8 is, for example, vertically connected to the mounting member 1. One end of the fixed block 8 is connected to one end of the mounting member 1 close to the first connecting portion 51, and the other end of the fixed block 8 is connected to the end of the elastic member 5 far from the first connecting portion 51 to form a second connecting portion 52. In the second direction X2, the first connecting portion 51 and the second connecting portion 52 are on the same straight line, and at the same time, the second connecting portion 52 and the moving member 4 are also on the same straight line. The elastic member 5 is arranged between the fixed block 8 and the moving member 4, and the moving member 4 is arranged between the elastic member 5 and the fixed handle 7. In other words, both the elastic member 5 and the moving member 4 are arranged between the fixed block 8 and the fixed handle 7.
[0059] In the above locking mechanism 100, by providing a fixing block 8 on the mounting member 1 and connecting the fixing block 8 to the elastic member 5, it is ensured that when the operator pulls the operating member 4, the pulling force applied to the operating member 4 and the reverse pulling force generated by the elastic member 5 are on the same line in the second direction X2, avoiding an oblique pulling force on the operating member 4. Furthermore, this prevents additional friction between the operating member 4 and the limiting block 2 and the locking member 3 under the action of the oblique pulling force, ensuring the smoothness when the operator pulls the operating member 4.
[0060] It can be understood that when the operator wants to change the working position of the flipping tooling with the above locking mechanism 100, the specific operation process is as follows: First, the operator's operating hand holds the fixed handle 7 and the movable handle 6 of the locking mechanism 100, and by bending the fingers to pull the movable handle 6, the operating member 4 is driven to move, and then the locking member 3 is driven to slide out of the limiting hole 921 of the tooling rack 9, realizing the unlocking of the working position of the workpiece fixing member 12 of the flipping tooling. Then, the operator's operating hand remains in the holding state, rotates the entire locking mechanism 100, and then drives the workpiece fixing member 12 to flip through the rotating shaft 10 of the tooling, changing the angle (i.e., the working position) of the workpiece fixing member 12. When the angle of the workpiece fixing member 12 is adjusted to the appropriate position, stop rotating the locking mechanism 100. At this time, the operator's operating hand releases the movable handle 6, and the movable handle 6 and the operating member 4 are reset, and then drive the locking member 3 to insert into the limiting hole 921, realizing the locking of the working position of the workpiece fixing member 12.

For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present invention.
