DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0024] Example 1

[0025] See also Figure 1 As shown, this embodiment provides an elastic grinding pestle, which includes: a buffer mechanism 100, the buffer mechanism 100 includes a nest 110, a buffer member 120 and a push rod 130, the buffer member 120 and the push rod 130 are both arranged inside the nest 110, wherein the buffer member 120 is connected between the inner wall of the nest 110 and the push rod 130, one end of the push rod 130 is connected to the buffer member 120, and the other end is passed through the outside of the nest 110; an angle adjustment mechanism 200, the angle adjustment mechanism 200 includes an assembly frame 210 and a connecting component 220, the assembly frame 210 is connected to the push rod 130, the connecting component 220 is connected to the assembly frame 210, and flips around the rotation center line 1001; a grinding member 300, the grinding member 300 is connected to the connecting component 220, and its grinding angle is adjusted by the connecting component 220.

[0026] The elastic grinding pestle described in this embodiment can relatively squeeze the buffer member 120 during the grinding process through the relatively movable push rod 130 and the nest 110, thereby achieving an squeezing and buffering effect on the grinding member 300, and further achieving a two-way protection effect on the mortar and the grinding member 300. During this process, the angle adjustment mechanism 200 can drive the grinding member 300 to perform adaptive angle adjustment during the grinding process, which can not only improve the application range of the grinding member 300 and improve the interaction between it and the mortar, but also expand its operating range, so that it has higher grinding efficiency and better grinding effect. Compared with conventional grinding equipment, this application has significant advantages such as easy operation, wide application range, sufficient grinding and long service life, and has broad application prospects in this industry.

[0027] See also Figure 1 As shown, the buffer mechanism 100 in this embodiment can be connected to an external grinding drive device to achieve the automatic grinding effect of the elastic grinding pestle. Specifically, this embodiment also includes a connecting rod 400, one end of which is connected to the buffer mechanism 100 and the other end is connected to the external grinding drive device. Furthermore, the buffer mechanism 100 is used to provide buffering protection between the grinding element 300 and the mortar during the actual grinding process. The angle adjustment mechanism 200 can adjust the operating angle of the grinding element 300 according to the size and shape of the actual mortar, making it compatible with different mortars, thereby expanding the use range of the elastic grinding pestle.

[0028] See also Figure 1 and Figure 2As shown, the nest 110 in this embodiment is preferably a cylindrical element with a hollow interior, which includes a top sealing plate, side walls and a baffle. The baffle is provided with a through hole for the push rod 130 to pass through. Furthermore, the baffle is arranged on the side of the nest 110 facing the angle adjustment mechanism 200. It has a sealing and protective function while also having a stopping and limiting function for the push rod 130.

[0029] Furthermore, the push rod 130 in this embodiment is preferably a rod-shaped element with a diameter smaller than the through hole, thereby serving as both a mounting platform for the angle adjustment mechanism 200 and a key element for enabling the elastic grinding pestle to have an elastic buffering effect. Specifically, during the actual grinding process, the grinding member 300 will exert pressure on the push rod 130, thereby causing it to squeeze the buffer member 120 and to undergo relative displacement with the nest 110, thereby achieving the purpose of alleviating impact pressure. Specifically, the buffer member 120 in this embodiment is preferably a compression spring. In other embodiments, the buffer member 120 can also be set to an elastic rubber, a spring or other element with an elastic recovery effect according to actual use requirements, and the present invention does not impose specific restrictions on this.

[0030] See also Figure 2 As shown, in this embodiment, to prevent the push rod 130 from disengaging from the nest 110 on one side of the baffle, the buffer mechanism 100 further includes a stopper 140. The stopper 140 is disposed on the periphery of the push rod 130 and abuts against the inner wall of the nest 110. In the direction of movement of the push rod 130, the projected area of the stopper 140 is greater than the projected area of the through hole. Based on this, the baffle can ensure that one end of the push rod 130 is always slidably disposed within the nest 110 through the stopper 140, thereby improving the safety and stability of the elastic grinding pestle during use. Specifically, this embodiment includes two stoppers 140, both of which are integrally disposed between the push rod 130.

[0031] See also Figure 1 As shown, in order to provide a mounting and connection platform for the grinding member 300, an assembly frame 210 is provided in this embodiment. The assembly frame 210 includes a main body 211 and two connecting arms 212. The main body 211 is connected to the push rod 130. The connecting arms 212 extend from the edge of the main body 211 toward the grinding member 300. The connecting assembly 220 is connected to the connecting arms 212 and has an inverted "U"-shaped cross-section. This protects the grinding member 300 while increasing the deflection range of the grinding member 300. In other embodiments, the assembly frame 210 can also be configured as other structures, and the present invention does not impose specific limitations on this.

[0032] See also Figure 3As shown, the connecting assembly 220 includes an adjustment frame 221 and a fixed frame 222. The adjustment frame 221 and the fixed frame 222 together define a connecting groove, into which the grinding member 300 is connected. Furthermore, when the adjustment frame 221 and the fixed frame 222 are connected, the connecting groove matches the dimensions of the grinding member 300. Furthermore, in this embodiment, the adjustment frame 221 serves as the primary structure for adjusting the angle of the grinding member 300 and is provided with a locking member that extends through and connects to the assembly frame 210. Specifically, the locking member in this embodiment is configured as a bird's beak or plum blossom-shaped bolt, which is convenient for the operator to adjust. When the locking member is in a locked state, the relative position between the adjustment frame 221 and the assembly frame 210 is fixed. At this time, the operating angle of the grinding member 300 can be fixed to achieve a stable grinding effect; when the locking member is in an unlocked state, the relative position between the adjustment frame 221 and the assembly frame 210 can be adjusted. At this time, the actual angle of the grinding member 300 can be flexibly adjusted according to the actual shape and size of the mortar.

[0033] See also Figure 3 As shown, the adjustment frame 221 in this embodiment includes a fixed portion 2212 and two symmetrically arranged rotating portions 2211. The two rotating portions 2211 are arranged on either side of the fixed portion 2212 and are respectively rotatably connected to the assembly frame 210. The fixed portion 2212 and the fixed frame 222 are detachably connected, wherein a locking member is provided on the rotating portion 2211. Specifically, the fixed frame 222 and the adjustment frame 221 are detachably connected via bolts. The corresponding positions of the bolts on the fixed frame 222 can be made of stainless steel to improve the connection stability. Furthermore, the rotation centerline in this embodiment runs through the centers of the two rotating portions.

[0034] The grinding member 300 in this embodiment includes a rod 310 and a grinding head 320 connected to each other, wherein the rod 310 is connected to the connecting assembly 220, and the grinding head 320 is positioned toward the mortar. The diameter of the rod 310 matches the connecting groove, and the grinding head 320 is in direct contact with the material to be ground.

Furthermore, it also includes a frame 600, which is provided with a support plate 610, an extension rod 620, and an adjustment rod 630. The mortar is disposed on the support plate 610. The extension rod 620 is connected between the support plate 610 and the adjustment rod 630, and the extension rod 620 extends along the height direction of the frame 600. One end of the adjustment rod 630 is rotatably connected to the extension rod 620, and the other end is connected to the push-rotating driver 500. Based on the above structure, the electric grinder in this embodiment can automatically grind after adjusting to the target angle, thereby achieving a high-quality and efficient processing process.

[0037] In summary, the elastic grinding pestle and electric grinder described in the present invention, through the relatively movable push rod 130 and the nest 110, relatively squeeze the buffer member 120 during the grinding process, thereby achieving an extrusion and buffering effect on the grinding member 300, and then achieving a two-way protection effect on the mortar and the grinding member 300. During this process, the angle adjustment mechanism 200 can drive the grinding member 300 to perform adaptive angle adjustment during the grinding process, which can not only improve the scope of application of the grinding member 300 and improve the interaction between it and the mortar, but also expand its operating range, so that it has higher grinding efficiency and better grinding effect. Compared with conventional grinding equipment, this application has significant advantages such as easy operation, wide scope of application, sufficient grinding and long service life, and has broad application prospects in this industry.
