The smaller the tooth pitch, the more precise the transmission of the rack and pinion structure. However, in this process, the gear teeth of the gear and the teeth of the rack are more likely to be worn and a gap occurs, thus resulting in the situation that the continuous pressure adjustment cannot be well achieved and the transmission mechanism fails.

Based on this, the embodiments of the present application avoid some of the problems noted above by improving the transmission mode. The pressure regulating device and the cutting device provided in the embodiments of the present application will be described below with reference to the relevant descriptions of some embodiments.

The moving member 300 is drivingly connected to the drive assembly 210 and slidably connected to the guide member 220 to reciprocate linearly along the first direction F1 driven by the drive assembly 210 . The drive assembly 210 includes a transmission member 211 having a centerline of rotation L1 (refer to FIGS. 8 and 9 shown later) and an output shaft 212 eccentrically disposed on the transmission member 211 . The moving member 300 is provided with a limit slot 310 , and the output shaft The 212 can extend into the limiting groove 310 and abut against the inner wall of the limiting groove 310 , so as to convert the rotational motion of the transmission member 211 into the linear motion of the moving member 300 . In some embodiments, please refer to FIG. 1 , the pressure regulating device 10 further includes a device body 110 and a casing 120 . The aforementioned pressure regulating mechanism 200 is installed on the device body 110 between the casing 120 and the device body 110 . The detachable connection allows the moving part 300 and the pressure regulating mechanism 200 to be accommodated in the space formed between the casing 120 and the device body 110, so that not only a good appearance can be obtained, but also the pressure regulating mechanism 200 and the movement of the pressure regulating mechanism 200 can be protected. 300 pieces. Of course, in other embodiments, referring to FIG. 5 shown later, a accommodating space for the pressure regulating mechanism 200 may also be formed in the moving member 300 to form a structure in which the moving member 300 is covered outside the pressure regulating mechanism 200 .

"Eccentrically disposed on the output shaft 212 of the transmission member 211" means that the rotation center of the output shaft 212 is different from the rotation center of the transmission member 211 and has a certain distance. It can be understood that, for the case where the rotation angle of the transmission member 211 is the same, the greater the distance caused by the eccentricity, the greater the rotation stroke of the output shaft 212, and the relative displacement between the output shaft 212 and the limiting groove 310 is also greater. The larger it will be, under this action, the moving member 300 follows the guide member 220 . The distance can be adjusted according to the stroke of the moving member 300 and the driving precision required for actual use, which is not specifically limited in this embodiment of the present application.

In some embodiments, the output shaft 212 and the transmission member 211 may be a one-piece structure or a split structure. When the output shaft 212 and the transmission member 211 are set as a split structure, the output shaft 212 and the transmission member 211 can be either fixedly connected or rotatably connected to achieve different degrees of flexibility. For example, when the output shaft 212 is rotatably connected to one side of the transmission member 211, different driving power sources can be configured between the output shaft 212 and the transmission member 211. In this way, by configuring different rotational speeds, more precise flexible control process.

That is to say, the relative movement of the output shaft 212 and the limit slot 310 is generated by the socket piece 213 , and the direct contact between the socket piece 213 and the inner wall of the limit slot 310 can not only reduce the output shaft 212 and the inner wall of the limit slot 310 The wear and tear generated between them can also facilitate the replacement of the socket part 213 and reduce the cost. Specifically, in some embodiments, the friction coefficient of the socket member 213 is smaller than the friction coefficient of the inner wall of the limiting groove 310 . In this way, it is convenient for the relative movement between the output shaft 212 and the limiting groove 310 to be more stable and smooth during the conversion process, so that the processing tool 20 can have a more stable processing process.

One end of the elastic member 230 is connected to the connecting member 214 . Alternatively, the connecting member 214 may be provided in the form of a connecting rod. The length of the connecting member 214 and the offset angle of the connecting member 214 relative to the center line L1 of rotation of the transmission member 211 can be set according to the usage requirements. In order to better realize pressure regulation, in some embodiments, please refer to FIG. 8 and FIG. 9 , the extension direction of the vertical line between the center axis of the output shaft 212 and the rotation center line L1 of the transmission member 211 is the second direction F2. The connecting member 214 has a first end connected with the peripheral edge of the transmission member 211, and a second end opposite to the first end. One end of the elastic member 230 is connected to the second end. The direction in which the first end points to the second end is the third direction F3, and the third direction F3 and the second direction F2 are parallel to each other. For example, as shown in FIG. 8 and FIG. 9 , the situation where the center of rotation of the transmission member 211 , the axis of the output shaft 212 and the third direction F3 are substantially located in the same plane is illustrated. The elastic force of the elastic member 230 on the connecting member 214 and the force of the output shaft 212 on the moving member 300 are located on the same side of the transmission member 211 , so that the motion conversion process can be flexibly adjusted more deeply.

Please continue to refer to FIG. 4 to FIG. 6 , in some embodiments, the transmission member 211 is a gear plate. The driving assembly 210 further includes a driving member (not shown), a first gear 215 drivingly connected with the driving member, and a gear set 216 engaged between the first gear 215 and the transmission member 211 . In this way, the transmission ratio of the transmission member 211 can be adjusted through the gear transmission process. Taking FIG. 4 to FIG. 6 as an example, it is illustrated that the gear set 216 is provided with two second gears, the two second gears are arranged on the same transmission shaft, and one of the two second gears is The first gear 215 is engaged, and the other one is engaged with the transmission member 211, so that the moving process of the moving member 300 can be adjusted more accurately. The number of the second gears may be selected and set according to the actual usage, which is not specifically limited in this embodiment of the present application.

In order to further combine the moving process of the linear motion of the moving member 300 to regulate the pressure of the overall device, please refer to FIG. 8 and FIG. 9 , in some embodiments, the transmission member 211 is an incomplete gear. Optionally, the central axis of the output shaft 212 and the rotation center line L1 of the transmission member 211 are parallel to each other, and a plane passing through the central axis of the output shaft 212 and the rotation center line L1 of the transmission member 211 is defined as the reference plane P. The gear teeth are located on both sides of the reference plane P and are symmetrical with respect to the reference plane P. As shown in FIG. That is to say, since a part of the edge of the transmission member 211 is provided with gear teeth, and a part is not provided with gear teeth, when the output shaft 212 and the limiting groove 310 move relatively, the process can at least include the following situations: (1) The second gear 216 meshes with the transmission member 211, the transmission member 211 drives the output shaft 212 to move, and the clockwise or counterclockwise rotation of the transmission member 211 will cause the elastic member 230 to generate a stretching elastic force between the transmission member 211 and the moving member 300. (2) The second gear 216 does not mesh with the transmission member 211, and there is no driving force acting on the transmission member 211. Since the moving member 300 has moved at this time, the elastic member 230 still has elasticity between the transmission member 211 and the moving member 300. Under the action of this elastic force, the movement of the moving member 300 will be rebounded and reset; (3) In the above-mentioned (2) situation and the basis for setting the output shaft 212 to be rotatable on the transmission member 211 In the above, the process of rebounding of the moving member 300 due to the elastic force can be adjusted more flexibly by the power of driving the output shaft 212 or the rotatability of the output shaft 212 . Thereby, a more precise pressure regulation process is achieved.
