Technical Field

[0001] The utility model relates to the technical field of tools, and more specifically, to a handle and a multi-functional shovel with the handle. Background Art

[0002] From the perspective of the usage conditions of multi-purpose shovels, it is necessary to meet the requirements of convenient carrying and convenient use. In terms of the convenient carrying performance, the multi-purpose shovels on the market are generally fixed and disassembled by screwing a threaded pipe, so as to realize disassembly for storage and carrying. Although the convenient carrying is achieved, the connection structure of the threaded pipe is very easy to loosen. After loosening occurs during use, it needs to be tightened again before it can be used again, causing inconvenience to users. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the problem that the handle structure with threaded connection in the prior art is easy to loosen, and provide a handle which can not only meet the functions of being easy to disassemble and carry, but also has an anti-loosening function to avoid loosening and detachment during use.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A handle includes a first pipe section and a second pipe section both of which are hollow. The first pipe section is threadedly connected to the second pipe section. A first limiting portion is provided at an end of the first pipe section close to the connection with the second pipe section. A button is rotatably connected to the second pipe section. A second limiting portion is provided on the button. An elastic member is installed at the bottom of the button, and the elastic member is detachably connected to the second pipe section. When the elastic member is in the original state, the first limiting portion and the second limiting portion are clamped and limited. When the button is pressed to rotate relative to the second pipe section, the elastic member is compressed by force, and the first limiting portion is disengaged from the second limiting portion. When the button is released, the elastic member applies a restoring force to the button to reset it.

[0006] The utility model realizes the detachable of the handle by threadedly connecting the first pipe section and the second pipe section, so as to facilitate the storage and carrying of the handle. The anti-loosening structure is formed by clamping the first limiting portion and the second limiting portion, and the button acts as a switch of the anti-loosening structure. When the button is pressed, the elastic member is compressed to create a clearance space for the button. The end of the button located at the elastic member swings downward, and the end of the button located at the second limiting portion swings upward, so that the second limiting portion is disengaged from the first limiting portion. At this time, the first pipe section and the second pipe section can be rotated relative to each other, so as to achieve the purpose of disassembling and separating the first pipe section and the second pipe section.

[0007] Disassembly principle of the handle: First, press the button. At this time, the end of the button located at the second limiting part swings upward and disengages from the first limiting part. Further, rotate the second pipe section, and the first pipe section can be separated from the second pipe section; Assembly principle of the handle: Rotate the second pipe section relative to the first pipe section. When the second limiting part of the second pipe section approaches the end of the first pipe section, the end of the first pipe section will push open the end of the button, so that the end of the second limiting part swings upward. Further, rotate the second pipe section. The button is subjected to the restoring force of the elastic member, and the end of the button close to the second limiting part has a tendency to swing downward. When the second limiting part is aligned with the first limiting part, the button swings downward, and the second limiting part is engaged with the first limiting part. At this time, the first pipe section and the second pipe section are locked, achieving the function of preventing the threaded pipe from loosening.

[0008] Further, an installation hole is provided on the side of the second pipe section. The first limiting part is located below the installation hole. The button is installed at the installation hole and is rotatably connected to the second pipe section through a rotating shaft. The second limiting part is located above the first limiting part. The installation hole is used for the installation of the button, and after the button is installed, the installation hole has the function of avoiding interference and making room, which is convenient for the button to swing up and down relative to the rotating shaft. Preferably, an inclined position is provided at the end of the second limiting part. The inclined position serves as a guiding structure, which is convenient for the end of the button to be pushed open when the second pipe section moves relative to the first pipe section, so that the second limiting part can smoothly enter the first limiting part to achieve the engagement function.

[0009] Further, one end of the elastic member is threadedly connected to the second pipe section through a screw, and the other end is located below the installation hole and is cantilevered. The elastic member is used to provide a restoring force for the button after being pressed by the button, so that the engagement limit between the second limiting part and the first limiting part can be maintained after the button is released. The cantilevered elastic member can cooperate with the up and down swing of the button to achieve the avoidance of the button.

[0010] Further, a sealing ring is also installed at the end of the second pipe section connected to the first pipe section. The sealing ring is sleeved outside the first pipe section and is located inside the second pipe section. The setting of the sealing ring provides a damping feeling during the rotation connection and cooperation process of the first pipe section and the second pipe section.

[0011] Further, the first limiting part is a through hole or a groove, and the second limiting part is an inverted hook-shaped protrusion. The anti-loosening of the first pipe section and the second pipe section is realized by the engagement limit between the second limiting part and the first limiting part.

[0012] Further, anti-slip patterns are provided on the outer surface of the button, and the anti-slip patterns are located at the end away from the second limiting part. The anti-slip patterns can increase the contact area to improve the anti-slip effect. Within the knowledge range of those skilled in the art, the anti-slip patterns can also be replaced by a number of protrusions or grooves.

[0013] Further, a third limiting portion is provided at the connection between the first pipe section and the second pipe section, and a fourth limiting portion is provided at the connection between the second pipe section and the first pipe section. The third limiting portion and the fourth limiting portion are in abutting connection for limiting. Preferably, the third limiting portion is a protrusion and the fourth limiting portion is a groove; or the third limiting portion is a groove and the fourth limiting portion is a protrusion. While the first pipe section and the second pipe section are threadedly connected, the protrusion and the groove are used in cooperation to achieve more precise positioning and fitting between the first pipe section and the second pipe section.

[0014] The present utility model also provides a multifunctional shovel, which includes a shovel head provided with a plurality of functional portions and a handle as described above. The shovel head is rotatably connected to the handle. The multifunctional shovel is a shovel that can achieve multiple functions. The multiple functional portions include a tip guiding portion, a shovel groove portion, and a shovel tooth portion. The tip guiding portion is provided at the end of the shovel head, the shovel groove portion is provided in the middle of the shovel head, and the shovel tooth portion is provided at the side of the shovel head; different functions of the shovel can be achieved; the handle facilitates grasping during the use of the shovel. Within the knowledge scope of those skilled in the art, the above-mentioned handle with detachable and anti-loosening functions can also be applied to other tools, such as hoes, ploughs, etc., as a handle.

[0015] Further, it further includes a connecting piece and a pin shaft. The connecting piece is detachably installed on the shovel head, and the handle is rotatably connected to the connecting piece through the pin shaft. The connecting piece is used to connect the handle and the shovel head, and the pin shaft is used to achieve the rotational connection between the handle and the connecting piece.

[0016] Further, a plurality of fifth limiting portions are sequentially provided on the connecting piece in the circumferential direction around the pin shaft, and a sixth limiting portion is provided at the end of the handle. The sixth limiting portion can be snap-connected and limited with the fifth limiting portion. Preferably, the fifth limiting portions can be a plurality of arc-shaped grooves, and the sixth limiting portion can be a protrusion. By rotating the handle along the pin shaft, the relative angle between the handle and the shovel head can be adjusted. Then, the relative position between the handle and the shovel head can be maintained without change after the relative angle between the handle and the shovel head is adjusted by using the snap connection and limitation between the sixth limiting portion and the fifth limiting portion. For the adjustment of the relative angle between the shovel head and the handle, the use of the multifunctional shovel can be further expanded to switch between states such as digging and planing.

[0017] The beneficial effects of the present utility model are as follows:

A second limiting portion 5 is provided on the button 4. An elastic member 6 is installed at the bottom of the button 4. The elastic member 6 is detachably connected to the second pipe section 2. When the elastic member 6 is in its original state, the first limiting portion 3 and the second limiting portion 5 are snap-connected for limiting. When the button 4 is pressed to rotate relative to the second pipe section 2, the elastic member 6 is compressed by force, and the first limiting portion 3 disengages from the second limiting portion 5. When the button is released, the elastic member 6 applies a restoring force to the button 4 to reset it.

[0032] The present utility model realizes the detachable connection of the handle 102 through the threaded connection between the first pipe section 1 and the second pipe section 2, facilitating the storage and carrying of the handle 102. The first limiting portion 3 and the second limiting portion 5 are snap-connected to form an anti-loosening structure, and the button 4 functions as a switch for the anti-loosening structure.
