[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] The utility model provides Figure 1-5 The crop tuber digging tool shown in the figure comprises a shovel body 1, a screw rod 2 is fixedly installed on the top of the shovel body 1, a pedal 3 located on the top of the shovel body 1 is movably sleeved on the screw rod 2, rake nails 4 are fixedly installed at both ends of the bottom of the pedal 3 and on both sides of the shovel body 1, and the bottom end of each rake nail 4 is a pointed cone, a connecting rod 6 is threadedly connected to the screw rod 2, a screw groove 7 is opened at the bottom end of the connecting rod 6, the screw groove 7 at the bottom end of the connecting rod 6 is threadedly sleeved on the screw rod 2, and the connecting rod 6 is fixedly installed at both ends of the bottom of the pedal 3 and on both sides of the shovel body 1. The bottom end is against the top of the pedal 3, and an outer tube 9 is movably sleeved on the outside of the connecting rod 6. Three groups of semicircular groove-shaped limiting grooves 12 are evenly opened on both sides of the outer wall of the connecting rod 6. Ball grooves 13 are opened at the bottom ends of both sides of the outer tube 9. Movable limiting balls 14 are arranged in the two ball grooves 13. The side walls of the two limiting balls 14 can be engaged in the limiting grooves 12 on both sides of the outer wall of the connecting rod 6. A threaded ring 15 located at the ball groove 13 is threadedly sleeved on the bottom end of the outer wall of the outer tube 9.

[0023] In order to facilitate the fixing of the outer tube 9 at different positions on the connecting rod 6, such as Figure 5 As shown, the diameters of the openings at both ends of the ball groove 13 are smaller than the diameter of the limiting ball 14. When one side of the limiting ball 14 contacts the inner wall of the threaded ring 15, the other side of the limiting ball 14 extends out of the ball groove 13 and is engaged in the corresponding limiting groove 12. The limiting ball 14 can move in the ball groove 13 to disengage from the limiting groove 12, and the threaded ring 15 is screwed to make it located at the ball groove 13. In this way, under the blocking effect of the threaded ring 15, the limiting ball 14 can no longer move in the ball groove 13, so that one end of the limiting ball 14 can be stably engaged in the limiting groove 12 of the side wall of the connecting rod 6, so that the position of the outer tube 9 can be fixed at a certain position on the connecting rod 6. When the position of the outer tube 9 needs to be adjusted, it is only necessary to screw the threaded ring 15 to make it leave the position of the ball groove 13. At this time, the limiting ball 14 will fall off the limiting groove 12 of the outer wall of the connecting rod 6 under external force, so that the position of the outer tube 9 can be adjusted.

[0024] In order to assemble the shovel body 1 and the connecting rod 6 in different ways, Figure 3As shown, a screw hole 8 penetrating the screw groove 7 is provided at the bottom end of the side wall of the connecting rod 6, and the screw hole 8 and the screw groove 7 are perpendicular to each other. The screw hole 8 at the bottom end of the side wall of the connecting rod 6 can be threadedly sleeved on the screw rod 2 at the top of the shovel body 1. When the screw rod 2 is threadedly inserted into the screw groove 7 at the bottom end of the connecting rod 6, the shovel body 1 and the connecting rod 6 are in a vertical state. This assembly method is convenient for the user to dig with his feet while standing. When the screw rod 2 is threadedly inserted into the screw hole 8 at the bottom end of the connecting rod 6, the shovel body 1 and the connecting rod 6 are in a perpendicular state. This assembly method is convenient for the user to dig while squatting.

[0025] In order to prevent the pedal 3 from rotating at any angle after installation, Figure 3 and Figure 4 As shown, both ends of the top of the shovel body 1 are provided with slots 16, and the bottom of the pedal 3 and both sides of the through opening 5 are provided with blocks 17, and the two blocks 17 at the bottom of the pedal 3 can be engaged in the two slots 16 at the top of the shovel body 1. Under the mutual engagement of the blocks 17 and the slots 16, the pedal 3 can be stably attached to the top of the shovel body 1 under the squeezing action of the bottom end of the connecting rod 6, so that the user can perform excavation work by stepping on the pedal 3 during the excavation process.

[0026] In order to increase the stability of the connection between the outer tube 9 and the connecting rod 6, as shown in FIG. Figure 3 As shown, a rod groove 10 is provided at the top of the connecting rod 6, and a reinforcing rod 11 is fixedly installed on the top of the inner wall of the outer tube 9. The bottom end of the reinforcing rod 11 is flush with the bottom end of the outer tube 9, and the reinforcing rod 11 is movably inserted into the rod groove 10 at the top of the connecting rod 6.

[0027] Finally, in order to protect the user's hands during the excavation process, such as Figure 1 and Figure 2 As shown, a rubber sleeve 18 is fixedly sleeved on the top of the outer tube 9. The rubber sleeve 18 can prevent the user's hands from being scratched and can greatly increase the friction between the user's hands and the outer tube 9, thereby preventing the tool from slipping out of the hand.

[0028] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
