Example (b): an agricultural device with a digging and supporting function, as shown in fig. 1 and fig. 2, comprises a digging shovel 1, a hand lever 11 fixedly connected with the digging shovel 1, and a pedal 12 arranged at the end part of the digging shovel 1, wherein the hand lever 11 is sleeved with a sliding part 13, and the side wall of the sliding part 13 is movably connected with a supporting frame 15 through a bolt 14; the top end of the hand lever 11 is provided with a limiting column 16 for limiting the sliding part 13 to fall off, and the outer diameter of the hand lever 11 is smaller than that of the limiting column 16. When the device is used for excavating crops or objects buried underground, the digging shovel 1 is directly vertically stepped by feet along the edge of the plant below the ground to reach the crops or the objects at a certain distance below the root of the plant, the hand lever 11 is swung to a certain extent, the digging shovel 1 continues to deeply penetrate the plant to play a role in cutting, at the moment, the supporting frame 15 is put down through the sliding piece 13, the sliding piece 13 slides to an action point along the hand lever 11, the lever principle is utilized, then the head of the hand lever 11 is moved to take out the crops, the purposes of saving time and labor and easing excavation are achieved, and the excavating efficiency is improved.

As shown in fig. 1 and 2, the supporting frame 15 includes supporting rods 17 symmetrically disposed at two sides of the sliding member 13, and further includes a bottom rod 18 fixedly connected to end portions of the two supporting rods 17; the supporting frame 15 is in an isosceles triangle structure. The support frame 15 of isosceles triangle structure, the width with ground contact is enough, also is convenient for being connected of support frame 15 and slider 13 more, also makes things convenient for accomodating of support frame 15 simultaneously, if adopt quadrangle or other structures's support frame 15, then will accomodate inconvenient or the many problems of materials.

As shown in fig. 1, 2 and 5, the top end of the limiting column 16 is provided with a fixing seat 21 connected by a spring 19. By utilizing the spring 19 and the fixed seat 21, when the support frame 15 is not required to be supported, the support frame 15 can be moved to the top end of the hand lever 11 through the sliding part 13 and then fixed on the fixed seat 21 through the contraction spring 19, so that daily storage and management are facilitated.

As shown in fig. 1 and 5, a clamping groove 22 is disposed at the top end of the fixing seat 21, and a clamping strip 23 clamped with the clamping groove 22 is disposed on the inner wall of the bottom rod 18. The connection between the fixed seat 21 and the supporting frame 15 is more stable.

As shown in fig. 1, 2 and 5, the bottom bar 18 is rotatably connected with a balance bar 24; the middle part of the bottom end of the bottom rod 18 is provided with a through hole 25 and a rotating shaft 26 which is in plug-in fit with the through hole 25, two opposite side walls of the bottom rod 18 are symmetrically provided with slots 27 for plug-in connection with the balance rod 24 along the center thereof, the rotating shaft 26 sequentially penetrates through the through hole 25 and the balance rod 24 and then is fixedly connected with the inner wall of the slot 27, and the balance rod 24 is rotatably connected with the rotating shaft 26. When the support frame 15 is supported on the ground, the supporting point supported on the ground is increased, so that the support frame 15 is prevented from toppling over and cannot play a supporting role, and meanwhile, when the balance bar 24 is not needed, the balance bar can be accommodated in the slot 27.

As shown in fig. 1, 3 and 6, four sliding strips 28 are uniformly arranged on the outer wall of the hand lever 11 along the circumferential direction of the hand lever, and the four sliding strips 28 are spirally arranged along the axial direction of the hand lever 11; the slider 13 is provided with a slide hole 29 into which the hand lever 11 is inserted. The connecting between the hand lever 11 and the sliding part 13 is convenient, the sliding strip 28 enables the sliding part 13 and the hand lever 11 to form a rotating fit, even if the sliding part 13 slides on the hand lever 11, the sliding part 13 must rotate along the circumferential direction of the sliding part, so that the sliding part 13 is prevented from moving on the hand lever 11 at will in the supporting process of the supporting frame 15, the supporting point of the hand lever 11 is changed, and the purposes of labor saving and convenient operation cannot be achieved; the function of the sliding strip 28 is similar to that of the screw thread, and all the sliding strips are used for limiting the sliding piece 13 to move freely on the hand lever 11, and the device uses four sliding strips 28 which are similar to the screw thread, so that the sliding hole 29 is not easy to damage the structure of the sliding strips 28 when being abutted against the outer wall of the hand lever 11, meanwhile, the four sliding strips 28 are convenient to contact with the hand of a user, the comfort degree is higher than that of the screw thread, and the sliding efficiency is improved compared with that of the screw thread on the two aspects.

As shown in fig. 3 and 4, the slider 13 is made of a roller; the slide hole 29 is arranged in the middle of the inner ring of the roller and the bolt 14 is arranged on the outer wall of the outer ring of the roller. By using the roller, when the slider 13 moves on the handle bar 11, the inner ring of the roller rotates, while the outer ring can not rotate, even if the support frame 15 does not rotate along with the inner ring of the roller when the slider 13 moves, so that when the position of the slider 13 is adjusted, the support frame 15 can be held by hand to move up and down, and the operation is convenient.

As shown in fig. 4, the sliding member 13 is made of at least one set of rollers, and the sliding holes 29 of the rollers are rotatably engaged with the handle bar 11. The rollers of one set make the sliding part 13 contact with the hand lever 11, so that the acting force applied on the rollers is reduced, and the rollers are prevented from being damaged.

As shown in fig. 1, 3, 4 and 6, the distance between adjacent slides 28 is not less than 5 cm. The sliding efficiency of the sliding piece 13 is improved, the structure of the sliding strip 28 is not easy to damage, and the comfort of the hand of the user is improved.

As shown in fig. 1, 2, 3 and 6, an arc-shaped slot 31 is provided between adjacent sliding strips 28, and four inner walls of the sliding hole 29 are all protruded inwards to form an arc-shaped block 32 which is in sliding fit with the arc-shaped slot 31. The sliding hole 29 is better matched with the hand lever 11 in a sliding way, so that the sliding friction force is reduced, and the sliding strip 28 and the sliding hole 29 are prevented from being damaged in the collision process.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
