[0031] The following refers to Figures 1 to 4 Describe the drafting tool according to an embodiment of the present invention.

[0032] As Figures 1 to 4 shown, the draft tool according to an embodiment of the present invention includes a base 100, a handle 200, a clamping pliers assembly, a pedal 400 and a clamping drive structure. The lower end of the handle 200 is fixedly connected to the base 100. The clamping pliers assembly includes a first clamping portion 310 and a second clamping portion 320 which are distributed oppositely. The first clamping portion 310 is fixedly arranged at the lower end of the handle 200. The upper end of the second clamping portion 320 is hinged to the base 100 through a clamping arm rotating shaft 902. The front end of the pedal 400 is pivotally connected to the base 100 through a pedal rotating shaft 902. The clamping drive structure includes a connecting component, a sliding member arranged on the connecting component, and a sliding groove 321 arranged in the middle of the second clamping portion 320 and slidably matched with the sliding member. The connecting component is detachably installed at the front end of the pedal 400. When the pedal 400 rotates relative to the base 100, it can drive the sliding member to slide in the sliding groove 321 to drive the first clamping portion 310 and the second clamping portion 320 to approach or separate from each other, so as to clamp weeds. When the connecting component is detached from the front end of the pedal 400, the second clamping portion 320 can rotate around the clamping arm rotating shaft 902 to open the first clamping portion 310 and the second clamping portion 320, so as to facilitate cleaning the first clamping portion 310 and the second clamping portion 320.

[0033] As Figure 1 、 Figure 3 shown, in some embodiments of the present invention, the sliding groove 321 slopes obliquely downward from back to front. When the pedal 400 rotates upward, it can drive the sliding member to move downward. The sliding member cooperates with the sliding groove 321 to drive the second clamping portion 320 to rotate towards the direction close to the first clamping portion 310, so as to realize clamping of weeds.

[0034] Specifically, as Figure 3 shown, when the draft tool is in use, it is inserted into the soil from top to bottom. The pedal 400 can be used to step on the resistance to insert the first clamping portion 310 and the second clamping portion 320 into the soil. After the first clamping portion 310 and the second clamping portion 320 are inserted to the required depth, the handle 200 rotates backward, and at the same time drives the base 100 to rotate clockwise. At this time, the pedal 400 is substantially stationary under the blocking force of the ground. The pedal 400 rotates counterclockwise (upward) relative to the base 100, thereby driving the sliding member to move downward. Through the sliding groove 321 which slopes obliquely downward from back to front, the second clamping portion 320 is pushed to move towards the first clamping portion 310, so as to clamp the weeds. Finally, the weeds are uprooted by rotating the handle 200.

[0035] In some embodiments of the present invention, the sliding member is a sliding shaft 510. Of course, in the specific implementation process, the sliding member can also be a slider, etc., which will not be elaborated here.

[0036] As Figure 4As shown, in some embodiments of the present invention, fork arms 410 are respectively arranged to extend forward on both sides of the front end of the pedal 400. The connecting components are two connectors 520 respectively detachably installed on the fork arms 410. Both ends of the sliding shaft 510 are respectively connected to the two connectors 520 correspondingly, thereby forming a stable clamping drive structure.

[0037] Specifically, the two fork arms 410 at the front end of the pedal 400 are respectively located on both sides of the base 100 and are detachably connected to the two connectors 520, so that the pedal 400 can apply forces to both ends of the sliding shaft 510 and can stably push the sliding shaft 510 to move.

[0038] As Figure 4 shown, in some embodiments of the present invention, the second clamping part 320 includes two clamping arms, and the two clamping arms are respectively provided with sliding grooves 321 to achieve a better clamping effect.

[0039] As Figure 4 shown, in some embodiments of the present invention, the connector 520 is detachably installed on the fork arm 410 through an insertion structure, and the disassembly and assembly are convenient and fast.

[0040] Of course, in the specific implementation process, the connector 520 can also be detachably installed on the fork arm 410 through a buckle structure or a threaded connection mechanism, which will not be elaborated here.

[0041] As Figure 2 、 Figure 4 shown, in some embodiments of the present invention, the pedal 400 is pivotally connected to the base 100 through a pedal rotating shaft 901. The fork arm 410 is provided with a recess 411 that can allow the connector 520 to be inserted from front to back. The connector 520 is provided with a clamping groove 521 that can be clamped on the shaft body of the pedal rotating shaft 901, thereby improving the installation stability of the connector 520 and the fork arm 410.

[0042] Specifically, when the drafting tool is in use, both the first clamping part 310 and the second clamping part 320 are inserted into the soil. During drafting, the second clamping part 320 is subjected to a force in the counterclockwise direction (roughly backward) by the soil, generating a backward force on the inserted connector 520, so that the connector 520 is tightly inserted into the recess 411 and is not likely to fall off, and the mechanism has high stability.

[0043] As Figure 4 shown, in some embodiments of the present invention, the clamping groove 521 is a U-shaped structure with an opening facing backward. The front end of the clamping groove 521 is an arc-shaped groove 521a corresponding to the shaft body of the pedal rotating shaft 901. The central angle corresponding to the arc-shaped groove 521a is greater than 180°, that is, the arc of the arc-shaped groove 521a is greater than a semicircle, so that the arc-shaped groove 521a can buckle the shaft body of the pedal rotating shaft 901 and make the connector 520 not likely to fall off.

[0044] As Figure 4 shown, in some embodiments of the present invention, the card slot 521 has a flared structure from front to back to facilitate the card slot 521 to be snapped onto the shaft body of the pedal rotating shaft 901.

[0045] In some embodiments of the present invention, the pedal 400 is made of plastic and the connecting member 520 is made of metal to improve the structural strength of the clamping drive structure. After the connecting member 520 is inserted into the recess 411 from front to back, the side wall of the recess 411 can generate a pushing force on the connecting member 520, so that the card slot 521 remains buckled on the shaft body of the pedal rotating shaft 901, improving the stability of the installation of the connecting member 520. When it needs to be removed, a relatively large external force can be applied to the connecting member 520 outward to overcome the elastic force of the side wall of the recess 411, and then the connecting member 520 can be pulled out.

[0046] As Figure 1 、 Figure 2 、 Figure 4 shown, in some embodiments of the present invention, the pedal rotating shaft 901 has a shaft nail structure and the connecting member 520 has a plate structure. When the card slot 521 of the connecting member 520 is snapped onto the shaft body of the pedal rotating shaft 901, the connecting member 520 is squeezed between the head of the pedal rotating shaft 901 and the fork arm 410, thereby improving the stability of the installation of the connecting member 520.

[0047] As Figure 4 shown, in some embodiments of the present invention, the fork arm 410 has a curved structure, so that the recess 411 has a curved structure in the front-back direction. The connecting member 520 has a plate structure and bends along with the recess 411 when the connecting member 520 is inserted into the recess 411. By using the deformation of the connecting member 520, the connecting member 520 and the recess 411 are tightly fitted, thereby improving the stability of the connection.

[0048] Specifically, in the projection along the up-down direction, the middle part of the fork arm 410 bends with a small curvature inward (towards the center of the base 100), and the recess 411 bends accordingly, so that the connecting member 520 inserted into the recess 411 deforms, and thus a tight fit is formed by using the deformation force.

[0049] In some embodiments of the present invention, a sliding guiding structure (not shown in the figure), such as a guide rail and a guide groove, is provided between the side surface of the connecting member 520 and the side wall of the recess 411, so that the fit between the connecting member 520 and the recess 411 is more compact, and the connecting member 520 can deform along with the recess 411 to achieve a better tight fit effect.

[0050] As Figure 2 、 Figure 4As shown, in some embodiments of the present invention, a U-shaped groove 412 capable of receiving the sliding shaft 510 is provided at the front end of the fork arm 410, so that the force of the pedal 400 can better act on the sliding shaft 510, facilitating the driving of the sliding shaft 510 to slide in the sliding groove 321.

[0051] As Figure 4 shown, in some embodiments of the present invention, the connecting member 520 is provided with a concave fastening position 522 capable of being fastened to the front end of the fork arm 410, so that the connecting member 520 is more closely attached to the fork arm 410, improving the stability of the installation.

[0052] As Figure 4 shown, in some embodiments of the present invention, the first clamping portion 310 is a concave structure opening towards the second clamping portion 320 to facilitate the clamping of weeds.

[0053] As Figures 2 to 4 shown, in some embodiments of the present invention, the drafting device is configured with a cleaning shovel 610 capable of sliding at the first clamping portion 310. The cleaning shovel 610 is matched with the first clamping portion 310 to facilitate the removal of foreign matters such as soil accumulated inside the first clamping portion 310.

[0054] As Figure 3 、 Figure 4 shown, in some embodiments of the present invention, the handle 200 is a pipe fitting. An active member 620 is slidably disposed inside the handle 200. The cleaning shovel 610 is disposed at the end of the active member 620. A sliding grip 630 connected to the active member 620 is slidably disposed outside the handle 200. By driving the sliding grip 630 to slide along the axial direction of the handle 200, the cleaning shovel 610 can be driven by the active member 620 to move up and down to clean the foreign matters such as soil accumulated inside the first clamping portion 310.

[0055] As Figure 3 、 Figure 4 shown, in some embodiments of the present invention, a compression spring 640 capable of driving the active member 620 to move upward is disposed inside the handle 200, so as to facilitate the reset of the cleaning shovel 610 to a higher position, avoiding affecting the normal insertion of the first clamping portion 310 into the soil.

[0056] Specifically, a limiting head 650 is disposed inside the handle 200. The lower end of the compression spring 640 abuts against the limiting head 650, and the upper end of the compression spring 640 abuts against the upper part of the active member 620, thereby generating an upward elastic thrust on the active member 620.

[0057] Of course, the present invention is not limited to the above embodiments. Those skilled in the art can make equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent deformations or substitutions are all included within the scope defined by the claims of this application.
