[0004] The utility model aims at overcoming the problems of the existing de -tithy ware without locking function, forming a security risk and being inconvenient to store, and provides a de -tithy ware, which can be locked in the closed state in the non -use state, can improve the safety factor, save storage space, and improve the convenience of storage.
[0005] To achieve the above object, the utility model adopts the technical scheme that:
[0006] A de -tithy ware, including first clamping body, second clamping body, pin shaft, the first clamping body with the second clamping body is rotated and is connected through the pin shaft, still including locking structure, the locking structure is installed in the first clamping body and / or second clamping body.
[0007] The de -tithy ware of the utility model can realize the de -tithy function by clamping the root part of vegetables and fruits through the first clamping body end and the second clamping body end, the first clamping body and the second clamping body connected by the pin shaft can adjust the distance between the two clamping bodies, and then facilitate the de -tithy after exerting force on the root, compared with the de -tithy ware of the prior art, the de -tithy ware of the utility model adds the locking function when the de -tithy ware is in the closed state, and the locking function is realized by the locking structure, when locking, the first clamping body and the second clamping body cannot be opened, so that the first clamping body and the second clamping body can be maintained in the locking state when closing, when unlocking, the first clamping body can be freely opened or closed with the second chuck, and the locking structure can also realize the locking and unlocking functions of the first clamping body and the second clamping body by other ways.
[0008] Further, the locking structure comprises a locking sheet and a torsion spring, the torsion spring is sleeved on the pin shaft, two ends of the torsion spring are respectively in abutment with opposite inner sides of the first clamping body and the second clamping body, the locking sheet is located between the first clamping body and the second clamping body, a movable hole is provided through the locking sheet, the pin shaft is located in the movable hole and protrudes from both ends of the locking sheet, and the locking sheet can move back and forth relative to the pin shaft; in the locked state, the torsion spring is compressed, the locking sheet is located at a first position and forms rotation limiting for the first clamping body and the second clamping body, and the first clamping body and the second clamping body remain closed; in the unlocked state, the locking sheet is located at a second position, and the torsion spring can push the first clamping body and the second clamping body to open outward. The cooperation of the locking sheet and the torsion spring can realize the locking or unlocking of the first clamping body and the second clamping body; specifically, the torsion spring is arranged on the pin shaft, when the enucleator is in the closed state, i.e., the first clamping body and the second clamping body are closed, the torsion spring is in a forced compression state, if at this time, the locking sheet is located at the first position, because the first clamping body and the second clamping body are limited by the locking sheet, there is no rotation space, so at this time, the enucleator is locked, and the first clamping body and the second clamping body remain closed; if at this time, the locking sheet is located at the second position, the rotation end of the first clamping body and the second clamping body is avoided, and the first clamping body and the second clamping body have a rotation space, then under the driving of the elastic restoring force of the torsion spring, the first clamping body and the second clamping body move in the direction away from each other, the enucleator is opened, and normal enucleation operation can be performed. Because the position of the pin shaft is always fixed, the enucleator moves the movable hole relative to the pin shaft by pushing the locking sheet, so as to change the position of the locking sheet relative to the pin shaft, so that the end of the first clamping body and the second clamping body connected in rotation is limited or has a rotation space, and the enucleator can be flexibly switched between the locked state and the unlocked state. In the non-use state, the enucleator is locked in the closed state, which can improve the safety factor, save storage space, and improve the convenience of storage.
[0009] Further, the lock piece comprises a locking portion and an unlocking portion connected with each other, the outer diameter of the locking portion is larger than that of the unlocking portion, the movable hole is located on the locking portion and / or the unlocking portion, and the movable hole comprises a locking hole and an unlocking hole connected with each other; when the lock piece is located at the first position, the pin shaft is located in the locking hole, and the locking portion is located at the end of the first clamping body and the second clamping body connected in rotation; when the lock piece is located at the second position, the pin shaft is located in the unlocking hole, and the unlocking portion is located at the end of the first clamping body and the second clamping body connected in rotation. By setting the outer diameters of the locking portion and the unlocking portion, when the locking portion of the lock piece is located at the end of the first clamping body and the second clamping body connected in rotation, the rotation of the first clamping body and the second clamping body is limited, and the closed locking state of the first clamping body and the second clamping body is maintained; when the unlocking portion of the lock piece is located at the end of the first clamping body and the second clamping body connected in rotation, the rotation of the first clamping body and the second clamping body is not limited, and the enucleator can be normally opened and closed. The setting of the locking hole and the unlocking hole can make the lock piece move relative to the pin shaft, and then change the position of the lock piece. The lock piece is made of flexible material, which can be slightly elastic. Preferably, the outer diameter of the pin shaft is slightly larger than that of the locking hole and the unlocking hole, so that the pin shaft and the locking hole or the unlocking hole are in interference fit, which can prevent the enucleator from changing between the locking state and the unlocking state due to accidental touch.
[0010] Further, the unlocking portion is in arc structure. The outer diameter of the arc-shaped unlocking portion changes from large to small, which can not only provide a space for the rotation of the first clamping body and the second clamping body, but also enable the first clamping body and the second clamping body to rotate around the arc-shaped structure when they rotate relative to each other, and limit the rotation angle of the two clamping bodies to a certain extent, so that the first clamping body and the second clamping body can be opened relative to each other, but not interfere with each other.
[0011] Further, the movable hole further comprises a limiting hole, one end of the limiting hole is communicated with the locking hole, and the other end of the limiting hole is communicated with the unlocking hole; the diameter of the limiting hole is smaller than that of the locking hole, and the diameter of the limiting hole is also smaller than that of the unlocking hole. The outer diameter of the pin shaft can be slightly smaller than that of the locking hole and the unlocking hole, but larger than that of the limiting hole. The pin shaft and the locking hole or the unlocking hole are in clearance fit, and the limiting hole is used for movement limiting; the limiting hole serves as a connection transition between the locking hole and the unlocking hole, so that the enucleator will not change state due to accidental touch when it is in the locking state or the unlocking state, thereby affecting normal use and improving safety.
[0012] Further, the lock piece further penetrates an avoiding hole, and the avoiding hole is located beside the movable hole. The avoiding hole can facilitate the movement of the lock piece relative to the pin shaft to switch the enucleator between the locking state and the unlocking state.
[0013] Further, the two avoiding holes are respectively located on two sides of the movable hole. The avoiding hole is obtained by hollowing out the lock piece. The lock piece can be switched between the first position and the second position through the avoiding hole.
[0014] Further, the lock piece further comprises a first pushing part and a second pushing part. The first pushing part is located at one end of the locking part away from the unlocking part. The second pushing part is arranged on the unlocking part. The movable hole is located on the locking part. The first pushing part is arranged to facilitate the movement of the lock piece from the second position to the first position, so as to switch the pedicle detacher from the unlocking state to the locking state. The second pushing part is arranged to facilitate the movement of the lock piece from the first position to the second position, so as to facilitate the switching of the pedicle detacher from the locking state to the unlocking state. Since the locking part has a larger outer diameter, the locking part has more internal space, which can facilitate the arrangement of the movable hole in the locking part.
[0015] Further, the lock piece further comprises a first pushing part and a second pushing part. The first pushing part, the locking part, the unlocking part, and the second pushing part are sequentially connected. The movable hole is located on the locking part. The first pushing part is an extension of the locking part away from the unlocking part. The second pushing part is an extension of the unlocking part away from the locking part. The first pushing part and the second pushing part are arranged to facilitate the movement of the lock piece.
[0016] Further, the first pushing part and / or the second pushing part are provided with anti-slip lines. The anti-slip lines can improve the anti-slip effect and facilitate the movement of the lock piece.
[0017] Further, the outer diameter of the pin shaft in the first direction is greater than the outer diameter of the pin shaft in the second direction. The hole diameter of the locking hole and the hole diameter of the unlocking hole are both greater than the outer diameter of the pin shaft in the first direction. The hole diameter of the limiting hole is smaller than the outer diameter of the pin shaft in the first direction and greater than the outer diameter of the pin shaft in the second direction. By setting the outer diameter of the pin shaft, when the lock piece is made of a rigid material and cannot be deformed, the direction of the pin shaft can be changed by rotating the pin shaft, so that the pin shaft can pass through the limiting hole from the unlocking hole to the locking hole, or the pin shaft can pass through the limiting hole from the locking hole to the unlocking hole. In fact, the pin shaft can only rotate, but its position does not change. Therefore, the change of the above-mentioned pin shaft in the locking hole or the unlocking hole is actually the change of the position of the lock piece. Only by rotating the pin shaft, the lock piece can be moved, so as to switch the pedicle detacher between the locking state and the unlocking state.
[0018] Further, the locking structure is respectively in sliding connection with the first clamping body and the second clamping body. By locking the first clamping body and the second clamping body through the locking structure, the first clamping body and the second clamping body can be maintained in the locking state when being closed; when being unlocked, the locking structure can be separated from the first clamping body and / or the second clamping body, so as to release the rotation limiting between the first clamping body and the second clamping body, thereby achieving the unlocking effect.
[0019] Further, the first clamping body or the second clamping body is provided with a limiting block for preventing the locking structure from being separated. Preferably, the limiting block is two, which are respectively arranged at the upper and lower limit positions of the sliding of the locking structure on the first clamping body, so that the locking structure is always connected with the first clamping body when being slid relative to the first clamping body, thereby avoiding being separated from the first clamping body; when being locked, the locking structure is in sliding connection with the second clamping body; when being unlocked, the locking structure is separated from the second clamping body, so as to release the rotation limiting between the first clamping body and the second clamping body. The first clamping body and the second clamping body are not limited in particular, and can refer to any side of the pedicle removal device.
[0020] Further, the locking structure is in rotation connection with the first clamping body and in movable buckling connection with the second clamping body. By arranging the locking structure on the first clamping body and making it in rotation connection with the first clamping body, when being locked, the locking structure is buckled with the second clamping body, so as to achieve the rotation limiting of the first clamping body and the second clamping body; when being unlocked, the locking structure is separated from the second clamping body, so as to release the rotation limiting between the first clamping body and the second clamping body. The first clamping body and the second clamping body are not limited in particular, and can refer to any side of the pedicle removal device.

[0042] The de-titling device of the present application can realize the de-titling function by clamping the root part of the vegetables and fruits with the first clamp body 1 end and the second clamp body 2 end and then pulling out; the first clamp body 1 and the second clamp body 2 rotatably connected by the pin shaft 3 can facilitate the adjustment of the distance between the two clamp bodies, and then facilitate the de-titling after the application of force to the root; compared with the de-titling device of the prior art, the de-titling device of the present application adds the function of locking when the de-titling device is in the closed state, which is realized by the locking structure 7, the locking structure 7 can be a switch arranged at the end of the rotatable connection of the first clamp body 1 and / or the second clamp body 2, when locked, the first clamp body 1 and the second clamp body 2 cannot be opened, so the first clamp body 1 and the second clamp body 2 can be maintained in the locked state when closed; when unlocked, the first clamp body 1 can be freely opened or closed with the second clamp head; the locking structure 7 can also realize the locking and unlocking functions of the first clamp body 1 and the second clamp body 2 through other ways.
[0043] As an improvement of the embodiment, the first clamping body 1 comprises a first handle 11 and a first blade 12, and the second clamping body 2 comprises a second handle 21 and a second blade 22, the first handle 11 and the second handle 21 are rotationally connected through the pin shaft 3, the first blade 12 is arranged at the end of the first handle 11 away from the pin shaft 3, and the second blade 22 is arranged at the end of the second handle 21 away from the pin shaft 3; the first blade 12 and the second blade 22 are close to or away from each other by moving the first handle 11 and the second handle 21 towards or away from each other, thereby realizing the clamping and loosening functions of the de-tither; the de-tither cooperates the first blade 12 and the second blade 22 to act on the root of the vegetable or fruit to perform the de-tither operation.
[0044] Specifically, the locking structure 7 comprises a locking plate 4 and a torsion spring 5, the torsion spring 5 is sleeved on the pin shaft 3, the two ends of the torsion spring 5 are respectively abutted against the opposite inner sides of the first clamping body 1 and the second clamping body 2, the locking plate 4 is located between the first clamping body 1 and the second clamping body 2, the locking plate 4 is provided with a movable hole penetrating therethrough, the pin shaft 3 is located in the movable hole and protrudes out of the locking plate 4 at both ends, and the locking plate 4 can move back and forth relative to the pin shaft 3; in the locked state, the torsion spring 5 is compressed, the locking plate 4 is located at the first position and forms a rotation limiting position for the first clamping body 1 and the second clamping body 2, and the first clamping body 1 and the second clamping body 2 remain closed; in the unlocked state, the locking plate 4 is located at the second position, and the torsion spring 5 can push the first clamping body 1 and the second clamping body 2 to open outward.
[0045] The cooperation of the locking plate 4 and the torsion spring 5 can realize the locking or unlocking of the first clamping body 1 and the second clamping body 2; specifically, the torsion spring 5 is arranged on the pin shaft 3, when the de-tither is in the closed state, i.e., the first clamping body 1 and the second clamping body 2 are closed, the torsion spring 5 is in a forced compression state, if at this time, the locking plate 4 is located at the first position, since the first clamping body 1 and the second clamping body 2 are limited by the locking plate 4, they do not have a rotation space, therefore, the de-tither is locked, and the first clamping body 1 and the second clamping body 2 remain closed; if at this time, the locking plate 4 is located at the second position, forming a clearance for the rotating end of the first clamping body 1 and the second clamping body 2, the first clamping body 1 and the second clamping body 2 have a rotatable space, then under the driving of the elastic restoring force of the torsion spring 5, the first clamping body 1 and the second clamping body 2 move in the direction away from each other, the de-tither is opened, and normal de-tither operation can be performed. Since the position of the pin shaft 3 is always fixed and unchanged, by pushing the locking plate 4, the movable hole moves relative to the pin shaft 3 to change the position of the locking plate 4 relative to the pin shaft 3, the end of the first clamping body 1 and the second clamping body 2 rotationally connected can be limited or have a rotation space, thereby realizing the flexible switching of the de-tither between the locked state and the unlocked state. In the non-use state, the de-tither is locked in the closed state, which can not only improve the safety factor, but also save the storage space and improve the convenience of storage.
[0046] Specifically, the locking piece 4 comprises a locking portion 41 and an unlocking portion 42 connected with each other, the outer diameter of the locking portion 41 is larger than that of the unlocking portion 42, the movable hole is located in the locking portion 41 and / or the unlocking portion 42, and the movable hole comprises a locking hole 61 and an unlocking hole 63 connected with each other; when the locking piece 4 is located at the first position, the pin shaft 3 is located in the locking hole 61, and the locking portion 41 is located at the end of the first clamping body 1 and the second clamping body 2 connected in rotation; when the locking piece 4 is located at the second position, the pin shaft 3 is located in the unlocking hole 63, and the unlocking portion 42 is located at the end of the first clamping body 1 and the second clamping body 2 connected in rotation.
[0047] By setting the outer diameters of the locking portion 41 and the unlocking portion 42, when the locking portion 41 of the locking piece 4 is located at the end of the first clamping body 1 and the second clamping body 2 connected in rotation, the rotation of the first clamping body 1 and the second clamping body 2 is limited, and the closed locking state of the first clamping body 1 and the second clamping body 2 is maintained; when the unlocking portion 42 of the locking piece 4 is located at the end of the first clamping body 1 and the second clamping body 2 connected in rotation, the rotation of the first clamping body 1 and the second clamping body 2 is released, and the forceps can be normally opened and closed. The setting of the locking hole 61 and the unlocking hole 63 can make the locking piece 4 move relative to the pin shaft 3, and then change the position of the locking piece 4. The locking piece 4 is made of flexible material, which can be an elastomer with slight deformation ability. Preferably, the outer diameter of the pin shaft 3 is slightly larger than that of the locking hole 61 and the unlocking hole 63, so that the pin shaft 3 and the locking hole 61 or the unlocking hole 63 are in interference fit, which can prevent the forceps from changing between the locked state and the unlocked state in the case of accidental touch.
[0048] Preferably, the unlocking portion 42 is in arc structure. The outer diameter of the unlocking portion 42 in arc structure changes from large to small, which can not only provide a space for the rotation of the first clamping body 1 and the second clamping body 2, but also can make the first clamping body 1 and the second clamping body 2 abut and rotate around the arc structure when they rotate relative to each other, and can limit the rotation angle of the two clamping bodies to a certain extent, so that the first clamping body 1 and the second clamping body 2 can be opened relative to each other, but not interfere with each other.
[0049] The movable hole further comprises a limiting hole 62, one end of the limiting hole 62 is communicated with the locking hole 61, and the other end is communicated with the unlocking hole 63; the diameter of the limiting hole 62 is smaller than that of the locking hole 61, and the diameter of the limiting hole 62 is also smaller than that of the unlocking hole 63. The outer diameter of the pin shaft 3 can be slightly smaller than that of the locking hole 61 and the unlocking hole 63, but larger than that of the limiting hole 62, the pin shaft 3 and the locking hole 61 or the unlocking hole 63 are in clearance fit, and the limiting hole 62 is used for movement limiting; the limiting hole 62 serves as a connection transition between the locking hole 61 and the unlocking hole 63, so that the forceps will not change state due to accidental touch when it is in the locked state or the unlocked state, which can affect the normal use and improve the safety.
[0050] As an improved scheme of the embodiment, the locking piece 4 is further provided with an avoiding hole 64 located beside the movable hole. The avoiding hole 64 can facilitate the movement of the locking piece 4 relative to the pin shaft 3 between the locking hole 61 and the unlocking hole 63 to meet the switching of the de-tither between the locking state and the unlocking state.
[0051] Further, the avoiding hole 64 is two, and the two avoiding holes 64 are located on the two sides of the movable hole. The avoiding hole 64 is obtained by hollowing out the locking piece 4. Through the setting of the avoiding hole 64, the locking piece 4 can be switched between the first position and the second position.
[0052] As an improved scheme of the embodiment, the locking piece 4 further comprises a first pushing part 43 and a second pushing part 44. The first pushing part 43 is located at one end of the locking part 41 away from the unlocking part 42, and the second pushing part 44 is arranged on the unlocking part 42. The movable hole is located in the locking part 41. The first pushing part 43 is arranged to facilitate the movement of the locking piece 4 from the second position to the first position, so as to switch the de-tither from the unlocking state to the locking state. The second pushing part 44 is arranged to facilitate the movement of the locking piece 4 from the first position to the second position, so as to facilitate the switching of the de-tither from the locking state to the unlocking state. Since the outer diameter of the locking part 41 is larger, the locking part 41 has more internal space, and the movable hole can be arranged in the locking part 41. The second pushing part 44 is recessed on the unlocking part 42, and is limited by the edge of the recess. When acting on the second pushing part 44, the locking piece 4 can be moved from the first position to the second position more easily.
[0053] Further, the first pushing part 43 and the second pushing part 44 are both provided with an indication mark. The indication mark is used to indicate the moving direction of the locking piece 4. Preferably, the indication mark on the first pushing part 43 is a triangular arrow pointing towards the unlocking part 42, and the indication mark on the second pushing part 44 is a triangular arrow pointing towards the locking part 41. The two indication marks are oppositely arranged.
[0054] Preferably, the first pushing part 43 and / or the second pushing part 44 are both provided with anti-skid lines. The anti-skid lines can improve the anti-skid effect and facilitate the movement of the locking piece 4.
[0055] Embodiment 2
[0056] The embodiment is an embodiment 2 of a de-tither. The embodiment is similar to the embodiment 1, and the difference lies in that the locking piece 4 further comprises a first pushing part 43 and a second pushing part 44. The first pushing part 43, the locking part 41, the unlocking part 42 and the second pushing part 44 are sequentially connected. The movable hole is located in the locking part 41. The first pushing part 43 is an extension of the locking part 41 away from the unlocking part 42, and the second pushing part 44 is an extension of the unlocking part 42 away from the locking part 41. The setting of the first pushing part 43 and the second pushing part 44 can facilitate the movement of the locking piece 4.
[0057] Embodiment 3
[0058] This embodiment is an embodiment 3 of the de-titling device, which is similar to embodiment 1, and the difference is that, as shown in Figure 6 The outer diameter of the pin shaft 3 in the first direction is greater than that in the second direction, the hole diameter of the locking hole 61 and the hole diameter of the unlocking hole 63 are both greater than the outer diameter of the pin shaft 3 in the first direction, and the hole diameter of the limiting hole 62 is smaller than the outer diameter of the pin shaft 3 in the first direction and greater than the outer diameter of the pin shaft 3 in the second direction.
[0059] By setting the outer diameter of the pin shaft 3, when the locking piece 4 is made of a rigid material and cannot be deformed, the direction of the pin shaft 3 can be changed by rotating the pin shaft 3, and then the pin shaft 3 can enter the locking hole 61 from the unlocking hole 63 through the limiting hole 62, or the pin shaft 3 can enter the unlocking hole 63 from the locking hole 61 through the limiting hole 62. In fact, the pin shaft 3 can only rotate, but its position does not change, as shown in Figure 7 and Figure 8 Therefore, the change of the above-mentioned pin shaft 3 in the locking hole 61 or the unlocking hole 63 is actually the change of the position of the locking piece 4. Only by rotating the pin shaft 3 can the locking piece 4 be pushed to move, and then the de-titling device can be switched between the locking state and the unlocking state.
[0060] As an improved scheme of this embodiment, the pin shaft 3 protrudes from the first clamping body 1 and the second clamping body 2 at both ends, and the pin shaft 3 is provided with a force receiving part, which is preferably a protrusion or a groove. The setting of the force receiving part can facilitate the artificial rotation of the pin shaft 3, so that the pin shaft 3 can be flexibly switched between the horizontal state in the first direction and the horizontal state in the second direction, in order to facilitate the locking and unlocking of the locking piece 4.
[0061] Embodiment 4
[0062] As shown in Figure 9 and Figure 10 This embodiment is an embodiment 4 of the de-titling device, which is similar to embodiment 1, and the difference is that the locking structure 7 is in sliding connection with the first clamping body 1 and the second clamping body 2. Specifically, the locking structure 7 is located on the opposite inner side of the first clamping body 1 and the second clamping body 2. By locking the first clamping body 1 and the second clamping body 2 with the locking structure 7, the first clamping body 1 and the second clamping body 2 can be maintained in the locking state when they are closed. When unlocking is needed, the locking structure 7 can be separated from the first clamping body 1 and / or the second clamping body 2 to release the rotation limiting between the first clamping body 1 and the second clamping body 2, thereby achieving the unlocking effect.
[0063] Further, the first clamp body 1 or the second clamp body 2 is provided with a limiting block for preventing the locking structure 7 from disengaging. Preferably, the limiting block is two, which are respectively arranged at the upper and lower limit positions of the locking structure 7 sliding on the first clamp body 1, so that when the locking structure 7 slides relative to the first clamp body 1, the connection with the first clamp body 1 is always maintained, avoiding sliding out of disengagement from the first clamp body 1; and when locked, the locking structure 7 is in sliding connection with the second clamp body 2, and when unlocked, the locking structure 7 is disengaged from the second clamp body 2, so as to release the rotation limiting between the first clamp body 1 and the second clamp body 2. The first clamp body 1 and the second clamp body 2 are not specifically limited, and can refer to any side of the pedicle detacher.
[0064] Embodiment 5
[0065] As Figure 11 and Figure 12 Embodiment 5 of the pedicle detacher of the present embodiment is shown, which is similar to Embodiment 1, and the difference is that the locking structure 7 is in rotational connection with the first clamp body 1 and in active buckling connection with the second clamp body 2. Specifically, the locking structure 7 is located at the opposite inner side of the first clamp body 1 and the second clamp body 2, by arranging the locking structure 7 on the first clamp body 1 and making it in rotational connection with the first clamp body 1, when locked, the locking structure 7 is buckled with the second clamp body 2, so as to realize the rotation limiting of the first clamp body 1 and the second clamp body 2; when unlocked, the locking structure 7 is disengaged from the second clamp body 2, so as to release the rotation limiting between the first clamp body 1 and the second clamp body 2. The first clamp body 1 and the second clamp body 2 are not specifically limited, and can refer to any side of the pedicle detacher.
