Furthermore, the inner rod comprises a main body part and a piston part, the lower end of the outer tube extends along the radial direction to form a baffle ring, and the piston part is sleeved in the outer tube; the main body part is fixedly connected with the piston part and penetrates through the outer pipe from the inner cavity of the baffle ring.

Further, the main body part is in threaded connection with the piston part.

Furthermore, the lower end of the main body part is fixedly connected with a connecting rod, and the connecting rod is perpendicular to the main body part.

Furthermore, two ground nails arranged on opposite sides of the connecting rod are fixedly connected to two ends of the connecting rod.

Furthermore, the lantern ring includes ring body and screw rod, and screw rod one end is along radially the rigid coupling on the ring body outer wall, and screw rod and outer tube upper end threaded connection.

Furthermore, the shovel head is made of iron, a permanent magnet is embedded on the connecting rod, and the permanent magnet and the shovel head are mutually adsorbed.

Compared with the prior art, the shovel provided by the invention has the following advantages:

(1) the spade uses the bottom of the lantern ring as a fulcrum and the long handle as a lever to form a labor-saving lever, so that the spade can conveniently shovel soil; the flexibility and the rotation of the supporting rod and the clearance in the sleeve ring ensure the freedom degree of the long handle, and the limitation of the supporting rod on the movement of the long handle is reduced.

(2) According to the connecting rod, the permanent magnet and the shovel head are mutually adsorbed, and when the connecting rod is not used, the connecting rod is adsorbed on the back of the shovel head, so that the connecting rod is convenient to transport.

Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

A shovel, as shown in figure 1, comprises a shovel head 1, a long handle 2 and a supporting rod 3. An iron shovel head 1 is fixedly connected with one end of a long handle 2.

The support bar 3 includes a main bar 31, a collar 32 and a ground nail 33.

As shown in fig. 2, the main lever 31 includes an inner lever 311 and an outer lever 312. The inner rod 311 includes a body 3111 and a piston 3112, a stopper 313 is formed at the lower end of the outer tube 312 in a radially extending manner, and the piston 3112 is sleeved in the outer tube 312; body portion 3111 is threadably coupled to piston portion 3112 and extends through outer tube 312 from the interior of retainer 313. So that the outer tube 312 slides and rotates along the inner rod 311.

Main body portion 3111 has a lower end fixedly connected to link 34, link 34 is disposed perpendicular to main body portion 3111, and the lower end of main body portion 3111 is fixedly connected to the middle of link 34. And two ground nails 33 are arranged opposite to each other and vertically fixed at two ends of the connecting rod 34 respectively.

Collar 32 includes a ring 321 and a threaded rod 322. One end of the screw rod 322 is fixed on the outer wall of the ring body 321 along the radial direction, and the screw rod 322 is connected with the upper end of the outer tube 312 by screw thread, thereby fixing the lantern ring 32 on the upper end of the main rod 31. The ring body 321 is sleeved outside the long handle 2, and a gap for the long handle 2 to freely move relative to the support rod 3 is formed between the inner wall of the ring body 321 and the long handle 2.

In addition, in order to facilitate the movement of the support rod 3, a magnet as a permanent magnet is embedded in the link 34, so that the permanent magnet and the blade 1 are attracted to each other.

The working principle is that the stepping connecting rod 34 inserts the short ground nail 33 into the ground, then the shovel head 1 steps into the ground, and the shovel head 1 is lifted with soil by taking the bottom of the lantern ring 32 as a fulcrum and the long handle 2 as a lever; further, the blade 1 may be rotated about the inner rod 311 to move the blade 1 to another position.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
