[0022] The general garden shovel on the market has a relatively simple structure and is not very comprehensive in functions. When other operations are required, other tools are needed, which is not very convenient for gardeners to use, thereby reducing work efficiency, failing to meet people's needs, and bringing inconvenience to people's lives.

[0023] Therefore, the present invention provides a multifunctional garden shovel, which can effectively improve the above problems.

[0024] The multifunctional garden shovel according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0025] Reference Figures 1 to 7 As shown, a multifunctional garden shovel according to an embodiment of the present invention includes an operating handle 100 , a shovel head 200 , and a locking mechanism 300 .

[0026] The operating handle 100 is a portion for a user to hold, and is in the shape of a long rod as a whole.

[0027] The shovel head 200 includes a main body 210 and a connecting portion 220 fixedly connected to one end of the main body 210. The main body 210 is in the shape of a thin plate and is used to be inserted into the soil for gardening work such as shoveling, loosening, and digging. The connecting portion 220 is an intermediate structure for connecting the main body 210 with other components. The connecting portion 220 and the main body 210 can be welded into a whole, or connected by fasteners such as rivets and bolts; the connecting portion 220 is rotatable around a first axis and is arranged at one end in the length direction of the operating handle 100. Two locking holes 221 are provided on the connecting portion 220. The locking holes 221 pass through the connecting portion 220 along the extension direction of the first axis. The two locking holes 221 are arranged at intervals on the same circle around the first axis, and the two locking holes 221 are perpendicular to the vertical line connecting the first axis, and the extension direction of the first axis is perpendicular to the length direction of the operating handle 100.

[0028] The locking mechanism 300 includes a locking portion 310 and an elastic portion 320. The locking portion 310 is slidably installed on the operating handle 100 along a direction parallel to the first axis. The elastic portion 320 is arranged between the operating handle 100 and the locking portion 310, and is used to apply an elastic force to the locking portion 310 so that the locking portion 310 can be partially inserted into the locking hole 221, thereby limiting the rotation of the connecting portion 220 relative to the operating handle 100 and locking the connecting portion 220 to the operating handle 100; obviously, to release the lock of the connecting portion 220, it is only necessary to apply a reaction force greater than the elastic force of the elastic portion 320 to the locking portion 310, so that the locking portion 310 is disengaged from the locking hole 221, which is very convenient to operate.

[0029] The connecting portion 220 has at least a first state and a second state during the rotation process. In the first state, Figure 1As shown, the body 210 is arranged parallel to the operating handle 100, and the locking portion 310 is inserted into one of the locking holes 221. In the second state, the body 210 is arranged perpendicular to the operating handle 100, and the locking portion 310 is inserted into the other locking hole 221. That is, in the first state and the second state, as shown Figure 2 As shown, the locking portions 310 can be inserted into the locking holes 221 at corresponding positions to lock the fixed connecting portion 220 relative to the operating handle 100 , thereby locking the fixed body 210 relative to the operating handle 100 .

[0030] Obviously, when the connecting part 220 is in the first state, the main body 210 is distributed parallel to the operating handle 100. At this time, the multifunctional garden shovel as a whole can be regarded as a shovel, which can perform shoveling, loosening and other shoveling operations. When the connecting part 220 is in the second state, the main body 210 is distributed perpendicular to the operating handle 100. At this time, the multifunctional garden shovel as a whole can be regarded as a hoe, which can perform the functions of a hoe such as digging and weeding.

[0031] The multifunctional garden shovel with the above-mentioned structure can switch between the shovel form and the hoe form by simply switching the connecting part 220 between the first state and the second state. The functions of two tools are realized by one tool. The user does not need to carry multiple tools at the same time to meet various usage needs, thereby effectively improving work efficiency. In addition, by providing a locking part 310 that can be elastically movable to cooperate with the locking hole 221, when the state needs to be switched, it is only necessary to apply a reaction force greater than the elastic force of the elastic part 320 to the locking part 310 so that the locking part 310 is disengaged from the locking hole 221 to unlock. No special tools are required to unlock, and the locking part 310 can automatically reset after the external force is removed. The operation is very convenient and can further improve work efficiency.

[0032] Reference Figure 3 、 Figure 4 and Figure 7As shown, in some embodiments of the present invention, the operating handle 100 is provided with a mounting portion 110 , and the locking portion 310 includes a locking rod 311 and an abutting portion 312 . When the cam 312 is in the unlocking state, the locking lever 311 is locked and the locking lever 312 is locked in the unlocking state. The above structure is not only simple in structure and low in cost, but also stable and reliable in structure, and does not take up too much space.

[0033] Reference Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the mounting portion 110 includes a guide cylinder 111 and an end cap 112. The guide cylinder 111 is provided on the side wall of the operating handle 100 away from the connecting portion 220, and the guide cylinder 111 is distributed along the extension direction of the first axis; the end cap 112 is detachably connected to the end of the guide cylinder 111 away from the connecting portion 220, and a through hole is provided on the end cap 112 that passes through along the extension direction of the first axis; wherein the abutment portion 312 and the compression spring are both located in the guide cylinder 111, and the outer contour of the abutment portion 312 is adapted to the inner contour of the guide cylinder 111, so that The sliding of the locking rod 311 provides guidance, and the two ends of the compression spring respectively abut against the abutment portion 312 and the end cover 112 to apply elastic pressure to the locking rod 311. The locking rod 311 passes through the through hole of the end cover 112 to extend to the outside of the end cover 112, providing a suitable position for the user to apply force to the locking rod 311, and then pull out the locking rod 311; obviously, a hole for the locking rod 311 to pass through is provided on the operating handle 100 to avoid the locking rod 311.

[0034] By adopting the above-mentioned structure, the compression spring can be placed inside the guide cylinder 111 to reduce the contact between the compression spring and the external environment, effectively reduce the erosion of the compression spring by the external environment, and improve its service life; in addition, when the connecting portion 220 is in the first state, such as Figure 1 As shown, the multifunctional garden shovel is in the shape of a shovel as a whole. In this state, the guide cylinder 111 can also provide a stepping position for the user to facilitate the insertion of the main body 210 of the shovel head 200 into the soil, killing two birds with one stone.

[0035] Based on the above embodiment, refer to Figure 5 As shown, it is conceivable that an external thread can be provided on the outer peripheral wall of the guide cylinder 111, and an internal thread can be provided on the inner side of the end cover 112, so that the end cover 112 is threadedly connected to the guide cylinder 111 to facilitate disassembly and assembly, thereby improving maintenance efficiency.

[0036] Reference Figure 3 、 Figure 4 and Figure 7 As shown, in some embodiments of the present invention, the locking portion 310 also includes a manual portion, which includes a threaded barrel 313 and a pull plate 314. The locking rod 311 is provided with an external thread, and the inner wall of the threaded barrel 313 is provided with an internal thread and is threadedly installed on the locking rod 311. The threaded barrel 313 is located on the side of the end cover 112 away from the guide barrel 111, and the pull plate 314 is fixed to the end of the threaded barrel 313 away from the end cover 112 and protrudes from the outer peripheral wall of the threaded barrel 313. Along the extension direction of the first axis, there is a gap between the pull plate 314 and the end cover 112, so that when the locking rod 311 needs to be disengaged from the locking hole 221, the user can place his fingers in the gap between the pull plate 314 and the end cover 112, and pull the locking rod 311 by pulling the pull plate 314, which is very convenient to operate.

[0037] It is conceivable that the threaded barrel 313 and the pull plate 314 can be integrally formed or connected by welding.

[0038] Reference Figure 1 、 Figures 3 to 5 As shown, in some embodiments of the present invention, the operating handle 100 includes a fixed handle 120, an adjusting screw 130, and a handle 140. The fixed handle 120 is provided with a threaded mounting hole 121 extending along its length; the adjusting screw 130 is threadedly mounted in the threaded mounting hole 121 and partially extends out of the threaded mounting hole 121; the handle 140 is fixedly connected to the end of the adjusting screw 130 away from the fixed handle 120. By rotating the handle 140, the adjusting screw 130 can be moved relative to the fixed handle 120 along the length of the fixed handle 120, thereby adjusting the overall length of the operating handle 100 to meet different usage requirements and provide high flexibility; wherein, the shovel head 200 is connected to the end of the fixed handle 120 away from the adjusting screw 130.

[0039] Based on the above embodiments, it can be imagined that in order to avoid easy relative rotation between the adjusting screw 130 and the fixed handle 120 when the length adjustment is not required, the adjusting screw 130 and the threaded mounting hole 121 can be connected by a self-locking thread (such as a serrated thread or a trapezoidal thread), and the thread itself has high friction or mechanical interference to prevent loosening.

[0040] Reference Figure 4As shown, in some embodiments of the present invention, the operating handle 100 also includes a reinforcing sleeve 150, which is fixedly connected to the handle 140 and sleeved on the fixed handle 120. The adjusting screw 130 is located on the inner side of the reinforcing sleeve 150. By providing the reinforcing sleeve 150, on the one hand, the overall structural strength of the operating handle 100 can be improved through the cooperation between the reinforcing sleeve 150 and the fixed handle 120, and the bending and deformation of the adjusting screw 130 can be avoided. On the other hand, by providing the reinforcing sleeve 150, it can be convenient for users to hold it. On the other hand, the adjusting screw 130 is built into the reinforcing sleeve 150, and the overall structure is also more beautiful.

[0041] It is conceivable that both the adjusting screw 130 and the reinforcing sleeve 150 can be welded and fixed to the handle 140 . During manufacturing, the adjusting screw 130 and the handle 140 are welded first, and then the reinforcing sleeve 150 is welded to the handle 140 .

[0042] Reference Figure 4 and Figure 5 As shown, in some embodiments of the present invention, the end of the adjusting screw 130 away from the handle 140 is conical, and the end of the reinforcing sleeve 150 away from the handle 140 is flush with the end of the adjusting screw 130 away from the handle 140. The end of the reinforcing sleeve 150 away from the handle 140 is provided with a plurality of drilling teeth 151 arranged along its circumference. In this way, when the ground is hard, the adjusting screw 130 and the reinforcing sleeve 150 can be unscrewed from the fixed handle 120 together, and then the conical end of the adjusting screw 130 is placed downward against the ground. Then, the handle 140 is rotated, and the tip of the adjusting screw 130 and the drilling teeth 151 of the reinforcing sleeve 150 are used to drill into the ground, thereby loosening the soil and allowing soil sampling. Obviously, after use, the soil in the reinforcing sleeve 150 needs to be cleaned out.

[0043] Based on the above embodiments, in some specific embodiments, such as Figure 3 As shown, an anti-slip sleeve 152 is provided on the reinforcing sleeve 150. The anti-slip sleeve 152 can be made of rubber material. When in use, the operator can hold the anti-slip sleeve 152 to prevent the reinforcing sleeve 150 from slipping out of the hand due to sweating of the palm, thereby improving safety during use.

[0044] Reference Figure 1 、 Figure 3 and Figure 6As shown, in some embodiments of the present invention, the operating handle 100 includes a mounting frame 160, and along the extension direction of the first axis, the mounting frame 160 is respectively provided with mounting plates 161 on opposite sides of the connecting portion 220, that is, the two mounting plates 161 are respectively located on opposite sides of the connecting portion 220 along the extension direction of the first axis; a rotating shaft 162 is provided between the two mounting plates 161 to rotate the mounting connecting portion 220, and the center line of the rotating shaft 162 is the first axis; wherein, the connecting portion 220 is respectively fitted with the opposite sides of the two mounting plates 161, so that the two mounting plates 161 provide a certain limit for the connecting portion 220, effectively preventing the connecting portion 220 from twisting and improving the structural stability; in this embodiment, the locking mechanism 300 is provided on the mounting plate 161.

[0045] In some specific embodiments, the mounting bracket 160 is fixedly connected to an end of the fixing handle 120 away from the adjusting screw 130 , and the two can be connected and fixed by welding.

[0046] In some specific embodiments, such as Figure 3 and Figure 4 As shown, the guide cylinder 111 of the mounting portion 110 is fixed to the side wall of the mounting plate 161 facing away from the connecting portion 220, and the two are integrally structured. Obviously, the mounting plate 161 is provided with a hole for the locking rod 311 to pass through. In a further embodiment, both mounting portions 110 are provided with mounting portions 110 and are respectively equipped with a locking mechanism 300. The locking rods 311 of the two locking mechanisms 300 are aligned along the extension direction of the first axis. That is, the locking rods 311 of the two locking mechanisms 300 can be simultaneously inserted into the same locking hole 221, thereby improving the locking effect.

[0047] Reference Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, in some embodiments of the present invention, the mounting frame 160 is provided with a positioning block 163 between the two mounting plates 161, and the connecting portion 220 is in the first state, as shown in FIG. Figure 7 As shown, the connecting portion 220 abuts against the positioning block 163. By abutting the positioning block 163 with the connecting portion 220, the locking portion 310 can be quickly aligned with the locking hole 221, thereby improving work efficiency. In the second state, the connecting portion 220 is Figure 2 and Figure 5 As shown, the connecting portion 220 abuts against the side of the mounting plate 161 . Similarly, the connecting portion 220 can be quickly positioned to achieve rapid alignment of the locking portion 310 and the locking hole 221 , thereby improving work efficiency.

[0048] It is understandable that in order to reduce the overall material consumption of the connecting portion 220, in some embodiments, such as Figure 3As shown, the connecting portion 220 includes a connecting rod 222 and an arc-shaped extension rod 223. The connecting rod 222 is used to be fixedly connected to the main body 210 and to be rotatably connected to the rotating shaft 162. The arc-shaped extension rod 223 is arc-shaped, welded and fixed on the connecting rod 222, and extends along the circumferential direction of the rotating shaft 162. One locking hole 221 is set on the connecting rod 222, and the other locking hole 221 is set on the arc-shaped extension rod 223.
