Description

Technical Field

[0001] The utility model relates to the technical field of cutting tools, in particular to a Dalbergia rosea cutting puncher. Background Art

[0002] Dalbergia is a deciduous tree of the genus Dalbergia in the Fabaceae family. There are two ways of propagation of Dalbergia: seed propagation and vegetative propagation. Vegetative propagation mainly includes cuttings, grafting and other methods.

[0003] The cutting propagation of Dalbergia odorifera is generally carried out in spring or autumn, when the temperature is suitable and the air humidity is high, which is conducive to the rooting of the cuttings. The cutting medium requires looseness, air permeability and good water retention. Generally, river sand, perlite, peat soil, etc. can be selected as the cutting medium.

[0004] Before cutting, it is necessary to punch holes in the cutting substrate to facilitate the insertion of cuttings. Common handheld hole punchers consist of a handle and a hole-forming part, which are fixedly connected, such as a portable soil hole punch disclosed in Chinese patent publication number "CN205284448U".

[0005] However, the fixed hole-forming components are limited in the hole diameter shaping during punching and cannot meet the actual punching requirements for cuttings with different stem diameters. Based on this, in order to further optimize the applicability of existing punchers, we propose a Dalbergia rosea cutting puncher. Utility Model Content

[0006] The utility model aims to solve the shortcomings of the prior art that the cutting requirements of cuttings with different rod diameters cannot be met during actual punching, and a Dalbergia rosea cutting puncher is proposed.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] Design a Dalbergia rosea cutting puncher, comprising:

[0009] The handle body has a gripping portion and a connecting portion;

[0010] The insertion plug is provided with a locking portion, a hole forming portion and a spike portion in sequence from top to bottom;

[0011] A connecting rod is fixed at the bottom of the connecting part, a hole matching the connecting rod is opened on the end surface of the locking part, and a locking component is arranged between the connecting rod and the hole.

[0012] Further, the locking assembly includes a driving rod inserted in the connecting portion and having a bottom portion passing through the connecting rod;

[0013] An inner shrink ring groove is provided on the outer side of the driving rod, a limiting bead is arranged in the inner shrink ring groove, and an avoidance hole for the limiting bead to pass through is provided on the end surface of the connecting rod.

[0014] Furthermore, a spring is fixedly connected between the driving rod and the connecting portion, and one end of the driving rod passes through and extends to the outside of the holding portion.

[0015] Furthermore, a limiting hole is provided in the hole position of the locking portion, and a portion of the limiting bead protruding from the outside of the connecting rod is clamped in the limiting hole.

[0016] Furthermore, an anti-fool-proofing protrusion is arranged on the outer side of the connecting rod along its axial direction, and an anti-fool-proofing socket matched with the anti-fool-proofing protrusion is arranged in the hole.

[0017] Furthermore, a scale mark is provided on the outer side of the hole forming portion along its axial direction, and the scale mark is used to indicate the hole forming depth.

[0018] The utility model proposes a Dalbergia cutting puncher, which has the beneficial effect that: in the utility model, the handle body and the cutting plug are designed with a detachable structure, and the cutting plug can be set with multiple specifications of different outer diameters according to needs. In this way, in the actual punching process, the corresponding cutting plug specifications can be selected according to the different diameters of the Dalbergia rods to be cut, which effectively improves the convenience and applicability of the Dalbergia cutting operation. Secondly, scale marks are also provided on the outside of the cutting plug to realize intuitive observation of the cutting depth during cutting, so as to facilitate real-time regulation of the insertion depth. The overall structure is simple, which improves the convenience of the punching operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-3 An embodiment of the utility model discloses a Dalbergia cutting puncher, which is used to solve the problem that the traditional puncher has a single hole size when cutting Dalbergia, and is difficult to adapt to Dalbergia with different stem diameters. Specifically, the puncher includes a handle body 1, and the handle body 1 has a gripping portion 11 and a connecting portion 12. Specifically, the connecting portion 12 in this embodiment is vertically connected to the middle of the gripping portion 11, and forms a T-shaped structure as a whole;

[0025] And the insertion plug 2, which is sequentially arranged from top to bottom as a locking portion 21, a hole-forming portion 22 and a spike portion 23, wherein the hole-forming portion 22 is a cylindrical structure. It should be noted that the insertion plug 2 described in this embodiment can be set in a variety of models, and the difference between the models is that the outer diameters of the hole-forming portion 22 and the spike portion 23 are different. Since the locking portion 21 needs to be subsequently docked, a standard part can be used. By adopting a design of a plurality of hole-forming portions 22 with different outer diameters, a punching operation with a variety of apertures can be realized, so as to meet the adaptation of the punching for different rod diameters when Dalbergia cuttings are cut to improve the stability of the cuttings;

[0026] A connecting rod 13 is fixed at the bottom of the connecting portion 12 , a hole 24 matching the connecting rod 13 is formed on the end surface of the locking portion 21 , and a locking assembly 3 is arranged between the connecting rod 13 and the hole 24 .

[0027] In some embodiments, the locking assembly 3 of the present invention includes a driving rod 31 inserted into the connecting portion 12 and having its bottom passing through the connecting rod 13;

[0028] An inner shrink ring groove 32 is provided on the outer side of the driving rod 31, and a limiting bead 33 is arranged in the inner shrink ring groove 32. An avoidance hole for the limiting bead 33 to pass through is provided on the end face of the connecting rod 13. It should be noted that the diameter of the avoidance hole described in this embodiment should be smaller than the diameter of the limiting bead 33 to prevent the limiting bead 33 from falling from the inside of the avoidance hole.

[0029] Furthermore, in order to achieve convenient control of the driving rod 31, a spring 34 is fixedly connected between the driving rod 31 and the connecting portion 12, and one end of the driving rod 31 passes through and extends to the outside of the holding portion 11. That is to say, during operation, the entire driving rod 31 can be driven to move by pressing the end of the driving rod 31 located on the holding portion 11. The design of the spring 34 allows the position of the driving rod 31 to be reset by the spring 34 after pressing, which is convenient for subsequent reciprocating operations.

[0030] Of course, in order to achieve the snap-fitting adaptation with the above-mentioned limiting beads 33, a limiting hole 25 is also opened in the hole position 24 of the locking portion 21 in this embodiment, and the part of the limiting bead 33 protruding from the outside of the connecting rod 13 is snap-fitted into the limiting hole 25. Preferably, the limiting beads 33 described in this embodiment are set to two, and of course, the limiting holes 25 are also set to two.

[0031] Specifically, when drilling holes for rosewood of different rod diameters, if the outer diameter of the hole-forming portion 22 of the current insertion plug-in 2 does not meet the requirements, the end of the driving rod 31 is pressed, and when the driving rod 31 moves in, the limiting bead 33 is attached to the outer wall of the driving rod 31 until the limiting bead 33 moves to the inner shrinkage groove 32 of the driving rod 31. The limiting bead 33 can move to the axis of the inner driving rod 31 due to the space provided by the inner shrinkage groove 32. At this time, the limiting bead 33 is separated from the limiting hole 25 in the hole position 24, and the entire insertion plug-in 2 can be removed to replace the insertion plug-in 2 with a suitable outer diameter. Similarly, when replacing, first connect the locking portion 21 of the new insertion plug-in 2 with the connecting rod 13, and reset the driving rod 31 to drive the limiting bead 33 to move outward until the limiting bead 33 is connected to the limiting hole 25 of the new insertion plug-in 2.

[0032] On the basis of the above-mentioned embodiment, in order to realize the fool-proof connection between the connecting rod 13 and the locking part 21, in this embodiment, an fool-proof protrusion 14 is further arranged along the axial direction on the outer side of the connecting rod 13, and an fool-proof socket 26 matched with the fool-proof protrusion 14 is arranged in the hole 24. That is to say, in this embodiment, through the plug-in adaptation effect of the fool-proof protrusion 14 and the fool-proof socket 26, the circumferential position of the connecting rod 13 and the locking part 21 can be accurately connected, so as to ensure the stability of the clamping of the limit bead 33 in subsequent actions.

[0033] In addition, in order to realize intuitive observation of the depth of cuttings during cuttings, in this embodiment, a scale mark 27 is further provided on the outer side of the hole-forming portion 22 along its axial direction. The scale mark 27 is used to indicate the hole-forming depth. That is, when the user holds the handle body 1 to drive the cutting insert 2 to apply pressure downward on the inserting bed to form a hole, the insertion depth can be intuitively observed according to the scale mark 27, so as to facilitate real-time regulation of the insertion depth.

[0034] In summary, in the utility model, the handle body 1 and the insertion plug 2 are designed with a detachable structure, and the insertion plug 2 can be set with multiple specifications of different outer diameters according to needs. In this way, in the actual drilling process, the corresponding specifications of the insertion plug 2 can be selected according to the different rod diameters of the Dalbergia to be inserted, which effectively improves the convenience and applicability of the Dalbergia insertion operation. Secondly, a scale mark 27 is also provided on the outside of the insertion plug 2 to realize intuitive observation of the insertion depth during cutting, so as to facilitate real-time regulation of the insertion depth. The overall structure is simple, which improves the convenience of the drilling operation.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
