For example, the first cutter 13 cuts the food into pieces, and the second cutter 15 cuts the food into strips.

Specifically, in some embodiments, the tool holder 11 may include a body 111, a receiving member 113 extending from the body 111, and a loading member 115. The housing member 113 and the loading piece 115 are mounted on the main body 111. The body 111 is provided with a receiving notch 1111, and the receiving member 113 extends from an edge (peripheral edge) of the receiving notch 1111 in a direction away from the mount 115.

The loading piece 115 is mounted on the body 111 and is located at the edge of the accommodating notch 1111, and the loading piece 115 is opposite to the first end 1135 of the accommodating member 113. The first cutter 13 is mounted to the loader 115. The second cutter 15 is mounted to the first end 1135 of the housing member 113 and is spaced apart from the first cutter 13, and the first cutter 13 and the second cutter 15 are each configured to cut food on the tray structure 60, and the cutting patterns of the first cutter 13 and the second cutter 15 are different. In one example, the first cutter 13 may be mounted on the loading member 115 by welding, riveting, gluing, or the like in a non-detachable manner, so that the stability of the mounting of the first cutter 13 can be ensured, and the first cutter is not easily detached when cutting food. In another example, the first tool 13 may also be removably mounted to the carrier 115 by screws, snaps, or the like, whereby removal of the first tool 13 for grinding or replacement may be facilitated when the first tool 13 becomes dull. Also, in one example, the second cutter 15 may be mounted to the first end 1135 of the receiving member 113 by welding, riveting, gluing, or the like, so that the stability of the mounting of the second cutter 15 may be secured, and the second cutter may not be easily detached when cutting food. In another example, the second tool 15 may be removably mounted to the first end 1135 of the housing member 113 by screws, snaps, or the like, whereby the second tool 15 may be dulled and the second tool 15 may be easily removed for grinding or replacement.

Specifically, the plurality of protruding portions 515 are provided on the outer surface of the spiral portion 513 at intervals, and extend in a direction away from the axial center portion 511. In one embodiment, the height between the plurality of bosses 515 is the same, so that the raising or lowering of the lift plate 631 is more stable when the lift plate 631 collides with a different boss 515. In another embodiment, the height between the plurality of protrusions 515 is different, for example, the height between the plurality of protrusions 515 is gradually increased or gradually decreased in the extending direction of the spiral part 513, and the arrangement of the plurality of protrusions 515 of different heights can increase the adjustment range of the height of the elevating plate 631 to be raised or lowered in the first direction (Z1/Z2), that is, increase the adjustment range of the food cutting thickness to some extent.

In one embodiment, the tray support 613 is non-removably fixedly coupled to the lifting assembly 63, so that the tray support 613 is prevented from being biased to affect the cutting efficiency after being subjected to pressure applied by food or other devices. In another embodiment, the tray support 613 is detachably connected to the lifting assembly 63, and the tray support 613 can move in the first direction (Z1/Z2) together with the lifting assembly 63, thereby enabling easy detachment when the tray support 613 is damaged due to long-term use or requires maintenance.

Referring to fig. 2 and 5, the embodiment of the application is only illustrated by taking the rotating structure 20 as the cam structure 50. In some embodiments, knob structure 70 may include a rotating member 71. The rotating member 71 is disposed outside the tool holder 11 and connected to the connecting end 21, and the cam structure 50 rotates relative to the tool holder 11 when the rotating member 71 rotates relative to the tool holder 11.

Specifically, in the case where the rotating member 71 is driven to rotate relative to the tool holder 11, the connecting end 21 can also rotate relative to the tool holder 11, thereby rotating the cam shaft 51 of the cam structure 50 relative to the tool holder 11. At this time, the contact position of the cam shaft 51 with the elevating assembly 63 is changed, so that the elevating assembly 63 and the tray assembly 61 are elevated or lowered together in the first direction (Z1/Z2). In some embodiments, where the connecting end 21 is a boss, the connecting end 21 can extend into the rotary member 71 such that the cam structure 50 rotates relative to the tool holder 11 upon rotation of the rotary member 71.

Referring to fig. 7 and 8, in some embodiments, the rotating member 71 may include a first groove 710, and a side of the rotating member 71 facing the tool holder 11 is recessed away from the tool holder 11 to form the first groove 710, and the connecting end 21 extends into the first groove 710. The connection length of the knob structure 70 and the connection end 21 is the length of the connection end 21 extending into the first groove 710.

Specifically, in some embodiments, in the case where the rotating member 71 is driven by an external force to move along the connecting end 21 in a direction away from the tool holder 11, that is, in the case where the rotating member 71 is pulled outward relative to the tool holder 11, the connecting end 21 can be separated from the first groove 710; under the condition that the rotating member 71 is not driven by external force, the connecting end 21 can extend into the first groove 710, and the connecting end 21 can be matched with the first groove 710, at this time, the cam structure 50 is stationary relative to the tool holder 11.

Referring to fig. 2 and 5, in some embodiments, the food cutting machine 100 may further include a connecting structure 90, wherein the connecting structure 90 is disposed through the rotating member 71 and the rotating structure 20, and the rotating member 71 can move relative to the connecting structure 90. Specifically, the rotary member 71 is movable along the connecting structure 90 relative to the tool holder 11, so that the knob structure 70 can be selectively engaged with or disengaged from the limit structure 80. Wherein, when the knob structure 70 is separated from the limit structure 80 and the connection end 21 is separated from the first groove 710, the rotating member 71 can rotate relative to the tool holder 11, so as to drive the connection end 21 to rotate together relative to the tool holder 11; in the case that the connecting end 21 rotates relative to the holder 11, the connecting structure 90 rotates together with the connecting end 21 relative to the holder 11. The connecting structure 90 is arranged, so that the rotating piece 71 can be stably arranged on the outer side of the tool apron 11, the stable matching of the knob structure 70 and the limiting structure 80 is ensured, and the working stability of the food cutting machine 100 is further improved; on the other hand, the moving direction of the rotating member 71 relative to the tool post 11 during pulling out can be limited, so that the problem that the knob structure 70 and the limiting structure 80 cannot be matched due to the position deviation of the rotating member 71 after being pulled out is avoided, and the normal operation of the food cutting machine 100 is ensured.

With continued reference to fig. 2 and 5, in some embodiments, the connecting structure 90 includes a blocking member 91, a connecting member 93, and a locking member 95. The blocking member 91 is disposed at an end of the rotary member 71 remote from the holder 11. The link 93 penetrates the stopper 91, the rotating member 71, and the rotating structure 20, and the rotating member 71 can move along the link 93. The locking member 95 is disposed at an end of the connecting member 93 opposite to the blocking member 91, and the locking member 95 is used for fixing the connecting structure 90 and the rotating structure 20.

In one embodiment, the blocking member 91 and the locking member 95 may be detachably connected to the connecting member 93 by a threaded connection, a snap connection, or the like. In another embodiment, the blocking member 91 may be non-detachably connected to the connecting member 93 by welding, gluing, or the like, so that the blocking member 91 is prevented from falling off when the rotating member 71 moves along the connecting member 93, thereby ensuring the normal operation of the food cutter 100. The locking member 95 can be connected with the connecting member 93 in a non-detachable manner by welding, gluing or the like, so that the stability of the connection between the connecting member 93 and the cam structure 50 can be improved, and the cam structure 50 can rotate along with the rotating member 71 relative to the tool holder 11 under the condition that the rotating member 71 rotates relative to the tool holder 11. In yet another embodiment, the blocking member 91, the connecting member 93 and the locking member 95 may be integrally formed, so that the assembling of the connecting structure 90 and the knob structure 70 can be facilitated, and the assembling efficiency of the food cutting machine 100 can be improved.

In some embodiments, the blocking member 91 is disposed outside the rotating member 71, and compared with the blocking member 91 disposed inside the rotating member 71, the rotating member 71 in this embodiment can be pulled out by a longer distance from the tool holder 11, so that the knob structure 70 and the limiting structure 80 can be prevented from being disengaged, and the knob structure 70 can be further guaranteed to rotate relative to the tool holder 11. In other embodiments, the blocking member 91 is at least partially disposed inside the rotating member 71, so that on one hand, the blocking member 91 can be prevented from interfering with other structures of the food cutter 100, and normal operation of the food cutter 100 is ensured; on the other hand, the appearance effect of the food cutter 100 can be enhanced.

Referring to fig. 8, in some embodiments, the rotating structure may further include a spring 73. At least part of the elastic member 73 is located in the rotating member 71, and the rotating member 71 can be pulled outwards relative to the tool holder 11 at the connecting end 21; the elastic member 73 provides an elastic restoring force in the case that the rotating member 71 is pulled outward against the tool holder 11.

Specifically, one end of the elastic member 73 is connected to the stopper 91, and the other end is connected to the rotation member 71. In the case that the rotating member 71 is not pulled outward, the rotating member 71 can be kept engaged with the limiting structure 80 by the elastic force of the elastic member 73, and at this time, the connecting end 21 extends into the first groove 710, thereby limiting the rotation of the rotating member 71 relative to the tool holder 11. In the case that the rotating member 71 is pulled outwards relative to the tool holder 11, the knob structure 70 is separated from the limiting structure 80, and the connecting end 21 is disengaged from the first groove 710, at this time, the elastic member 73 is compressed, so that an elastic restoring force can be provided, and when the rotating member 71 is not pulled outwards, the elastic restoring force is used to make the knob structure 70 engage with the limiting structure 80.

Referring to fig. 2 and 5, in some embodiments, the limiting structure 80 may be a plurality of limiting holes 81 formed on the tool holder 11. The rotating member 71 includes an abutting portion 711 and a holding portion 713, the abutting portion 711 abuts against the tool holder 11, and the holding portion 713 extends from the abutting portion 711 toward a side away from the tool holder 11 for holding by a user. The abutment 711 has a limiting projection 7111 on a side facing the holder 11, the limiting projection 7111 being engaged with any one of the limiting holes 81, and when the rotary member 71 is pulled outwardly relative to the holder 11, the rotary member 71 can be rotated to engage with a different one of the limiting holes 81, so that the rotary member 71 is limited to a different angular position. Wherein, the length of the knob structure 70 and the limit structure 80 are matched to limit the length of the protrusion 7111.

Specifically, in some embodiments, the limiting structure 80 is a plurality of limiting holes 81 formed on a sidewall 1131 of the tool holder 11. When the rotating member 71 is pulled outward against the side wall 1131, the rotating member 71 moves along the connecting member 93 in a direction away from the side wall 1131, and the restricting projection 7111 is separated from the restricting hole 81, so that the rotating member 71 can rotate to engage with different restricting holes 81, and the rotating member 71 is restricted at different angular positions. In some embodiments, the surface of the holding portion 713 may be provided with anti-slip lines to increase the friction of the holding, which is convenient for the operator to hold.

Wherein, in some embodiments, each limiting hole 81 may correspond to a boss 515 of one cam shaft 51, i.e., each limiting hole 81 corresponds to one thickness adjustment gear, for example, the number of limiting holes 81 may be nine, corresponding to nine gears, and an operator may rotate the cam member using the rotating member 71 to select different thickness adjustment gears.

In some embodiments, the stop 91 may include a stop 911 and an extension 913, the extension 913 extending from the stop 911 in the direction of the tool holder 11. The rotating member 71 may further include a second groove 715 and a third groove 717. The side of the rotating member 71 facing away from the tool holder 11 is recessed toward the tool holder 11 to form a second groove 715, at least a portion of the blocking portion 911 is located in the second groove 715, and the knob structure 70 moves along the connecting end 21 by a distance that the bottom 7151 of the second groove moves to a distance that abuts against the blocking portion 911. The bottom 7151 of the second groove is recessed toward the tool holder 11 to form a third groove 717, a portion of the extension rod 913 is located in the second groove 715, and another portion of the extension rod 913 is disposed through the third groove 717 and abuts against the connecting end 21, and an inner dimension of the third groove 717 is smaller than an inner dimension of the second groove 715.

Specifically, in some embodiments, the blocking portion 911 may be disposed outside the second groove 715, or the blocking member 91 may be at least partially disposed inside the second groove 715. The outer dimension of the blocking member 91 is smaller than or equal to the inner dimension of the second groove 715, so that the rotating member 71 can move relative to the connecting structure 90, and the blocking problem between the blocking member 91 and the rotating member 71 is avoided. In addition, the outer dimension of the blocking member 91 is larger than the inner dimension of the third groove 717, so as to limit the pulling distance of the rotating member 71 relative to the tool post 11, prevent the rotating member 71 from falling off, and further ensure the normal operation of the food cutting machine 100.

Referring to fig. 2, 5 and 8, in some embodiments, the distance that the knob structure 70 moves along the connecting end 21 is smaller than the connecting length of the knob structure 70 and the connecting end 21, and is greater than the mating length of the knob structure 70 and the limiting structure 80, i.e. the distance that the rotating member 71 pulls outward along the connecting end 21 relative to the tool holder 11, is required to be smaller than the length that the connecting end 21 extends into the first recess 710, and is greater than the length of the limiting protrusion 7111. In other words, when the rotary member 71 is pulled outward against the holder 11, the restriction protrusion 7111 is separated from the restriction hole 81 while the connection end 21 remains engaged with the first groove 710 in the case where the blocking portion 911 collides with the bottom portion 7151 of the second groove. Therefore, when the operator pulls the rotary member 71 outward relative to the tool holder 11, the rotary member 71 is not easily separated, and the normal operation of the food cutter 100 can be ensured.
