Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figure 1-6 As shown, a garden shovel for municipal gardening includes a support rod 1, an adjustment box 2, a shovel head 3 and a handle 4: the support rod 1 is set as a cavity structure, the outer wall of the bottom end of the support rod 1 is provided with an adjustment box 2, the shovel head 3 is provided below the adjustment box 2, the handle 4 is provided above the support rod 1, a portable replacement mechanism 5 is provided below the adjustment box 2, an adjustment control mechanism 6 is provided above the portable replacement mechanism 5, an anti-slip control mechanism 7 is provided above the adjustment control mechanism 6, and the portable replacement mechanism 5 includes a mounting tube 51, a threaded groove 52 and A threaded column 53 and a mounting tube 51 are arranged on the outer wall of the bottom end of the adjusting box 2. The bottom end of the mounting tube 51 is arranged as an open structure, and a threaded groove 52 is arranged on the inner wall of the side of the mounting tube 51. A threaded column 53 is installed on the internal thread of the threaded groove 52. The outer wall of the bottom end of the threaded column 53 is connected to the shovel head 3. When the shovel head 3 needs to be repaired or replaced, it is only necessary to rotate the shovel head 3 until the threaded column 53 is completely separated from the mounting tube 51. When installing, it is only necessary to adjust the threaded column 53 to a suitable position and then screw it into the inside of the threaded groove 52.

[0025] The adjustment control mechanism 6 includes an adjustment button 61 and a limit worm 62. The adjustment button 61 is rotatably mounted on the side outer wall of the adjustment box 2. The adjustment button 61 is connected to one end of the limit worm 62. The other end of the limit worm 62 is rotatably mounted on the side inner wall of the adjustment box 2. The side of the limit worm 62 is connected to a limit worm wheel 63. The limit worm wheel 63 is arranged on the outside of the limit shaft 64. The bottom outer wall of the limit shaft 64 is rotatably mounted on the bottom inner wall of the adjustment box 2. The top outer wall of the limit shaft 64 The wall is connected to the outer wall of the bottom end of the reciprocating screw rod 65, and a supporting chassis 66 is arranged on the outside of the reciprocating screw rod 65, and the supporting chassis 66 is slidably installed inside the supporting rod 1. The outer walls on both sides of the supporting chassis 66 are symmetrically provided with limit blocks, and the inner walls on both sides of the supporting rod 1 are symmetrically provided with limit grooves, and the limit blocks and the limit grooves are slidably installed. The top outer wall of the supporting chassis 66 is provided with a cavity column 67, and the cavity column 67 is slidably installed with the side inner wall of the supporting rod 1, and the top of the cavity column 67 The outer wall is connected to the handle 4; when the height of the garden shovel needs to be adjusted, the adjusting knob 61 needs to be turned clockwise to increase the height. When the adjusting knob 61 is turned, the limiting worm 62 will be automatically driven to rotate, and then the limiting worm wheel 63 will be driven to rotate. Then, the limiting worm wheel 63 will automatically drive the limiting shaft 64 to rotate, and then the reciprocating screw rod 65 will be driven to rotate. When the reciprocating screw rod 65 is rotated, it will automatically drive the supporting chassis 66 to move. Here, due to the setting of the limiting blocks provided on both sides of the supporting chassis 66 and the limiting grooves on the inner wall of the supporting rod 1 being slidably connected, the reciprocating screw rod 65 will only drive the supporting chassis 66 to realize the vertical reverse sliding trajectory movement when rotating, and then the movement of the supporting chassis 66 will automatically drive the cavity column 67 to lift. When the cavity column 67 is lifted, it will automatically drive the shovel head 3 to move upward, thereby achieving the setting of extending the overall height of the garden shovel. When the height reaches the required position, stop turning the adjusting knob 61. When lowering, just turn the adjusting knob 61 counterclockwise. The principle is the same as above.

[0026] When the handle 4 is in a state of being moved, the locking rim 72 is tightened and the locking rim 73 is tightened to the locking rim 74 so that the handle 4 can move upwards and downwards, thereby effectively preventing the handle 4 from sliding out of the way and thus preventing the handle 4 from sliding out.

[0027] When the utility model is in use, when the shovel head 3 needs to be repaired or replaced, at this time, it is only necessary to rotate the shovel head 3 until the threaded column 53 is completely separated from the installation tube 51. When installing, it is only necessary to adjust the threaded column 53 to a suitable position and then screw it into the inside of the threaded groove 52; when it is necessary to adjust the height of the garden shovel, it is necessary to rotate the adjusting knob 61 clockwise when raising it. When the adjusting knob 61 is rotated, it will automatically drive the limiting worm 62 to rotate and then drive the limiting worm wheel 63 to rotate. Subsequently, the limiting worm wheel 63 rotates and automatically drives the limiting shaft 64 to rotate and then drives the reciprocating screw rod 65 to rotate. When the reciprocating screw rod 65 rotates, it will automatically drive the supporting chassis 66 to move. Here, due to the setting of the limiting blocks on both sides of the supporting chassis 66 being slidably connected with the limiting grooves on the inner wall of the support rod 1, the reciprocating screw rod 65 will only drive the supporting chassis 6 when rotating. 6 realizes vertical reverse sliding track movement, and then the movement of the supporting chassis 66 will automatically drive the cavity column 67 to lift. When the cavity column 67 is lifted, it will automatically drive the shovel head 3 to move upward, thereby achieving the setting of extending the overall height of the garden shovel. When the height reaches the required position, stop turning the adjustment knob 61. When lowering, just turn the adjustment knob 61 counterclockwise. The principle is the same as above; the anti-skid pad 71 here is set to a sweat-absorbing material. When the anti-skid pad 71 needs to be replaced, at this time, you only need to pull the mounting cover 73 from the side of the handle 4 to the horizontal side. At this time, the anti-skid pad 71 is changed from a locked state to an active state, and then the anti-skid pad 71 is taken down from the outer wall of the handle 4. When installing, you first need to clip the anti-skid pad 71 to the outer wall of the handle 4, and then adjust the contact snap ring 72 to a suitable position and snap it into the inside of the contact snap groove 74 to complete the installation.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
