By setting the second guide rod 516, the moving block 514 is guided, facilitating the vertical movement of the moving block 514 and the sealing plate 515. By setting the sealing plate 515, the groove 513 can be sealed. The sealing plate 515 impacts the gear column 54 to move, driving the electric pickaxe shovel 3 to move, and then performing a crushing operation on the concrete.

[0063] Embodiment 3 further optimizes the electric pickaxe with an angle positioning function provided in Embodiment 1 or 2. Specifically, as Figure 4 and Figure 9 shown, a toothed groove 518 is provided on the right side of the moving plate 49. The toothed groove 518 is used in cooperation with the gear column 54. A second connecting rope 519 is connected to the surface of the moving block 514. The side of the second connecting rope 519 away from the moving block 514 penetrates the moving plate 49 and is connected to the middle section rod of the segmented independently controlled electric telescopic rod 48. The right section rod of the segmented independently controlled electric telescopic rod 48 is connected to the moving plate 49. The left side of the moving plate 49 is connected with a support roller through a support block. The second connecting rope 519 is used in cooperation with the support roller. The left side of the segmented independently controlled electric telescopic rod 48 is connected with a motor 520. The left side of the motor 520 is connected to the electric pickaxe body 1 through a support block.

[0064] Through the toothed groove 518, it can be meshed with the gear column 54. By driving the moving plate 49 to rotate through the motor 520 and the segmented independently controlled electric telescopic rod 48, and by clamping the drill rod with the moving plate 49, the drill rod is driven to rotate, and a drilling operation can be performed on the concrete, improving the applicability of the electric pickaxe.

[0065] The usage process of the electric pickaxe with an angle positioning function provided by the present invention is as follows:

[0066] S1. Knocking: By controlling the middle section rod of the segmented independently controlled electric telescopic rod 48 to extend, the moving plate 49 is driven to move. The moving plate 49 drives the sealing plate 515 to move. The sealing plate 515 pushes the gear column 54 to move. The gear column 54 drives the electric pickaxe shovel 3 to move horizontally. The gear column 54 synchronously drives the second limiting ring 512, the toothed ring 56, the support pipe 50, and the round plate 51 to move. The round plate 51 compresses the second spring 52. The electric pickaxe shovel 3 knocks and crushes the concrete. When the moving plate 49 returns to its original position, the second spring 52 pushes the round plate 51 back to its original position, and then drives the electric pickaxe shovel 3 back to its original position, repeating the cycle;

[0067] S2. Dust suction: During the rightward movement of the moving plate 49, the air on the right side is compressed, the pressure on the right side of the moving plate 49 increases, causing the one-way air outlet valve 427 to open and discharging the air on the right side of the moving plate 49. When the moving plate 49 moves leftward, the pressure in the right-side space decreases, causing the one-way air inlet valve 426 to open, and the air in the inner cavity of the dust collection box 425 is sucked into the inner cavity of the horizontal pipe 40. The dust collection box 425 absorbs dust, and the dust floating in the air during the construction process successively passes through the dust suction holes, the second circular pipe 423, the second hose 424, the dust collection box 425, and the collection mesh frame 429, and the dust is blocked and collected in the inner cavity of the collection mesh frame 429;

[0068] S3. Dust suppression: By controlling the contraction of the middle section rod of the segmented independently controlled electric telescopic rod 48 to drive the movement of the moving plate 49, the moving plate 49 pushes the connecting plate 43 to move, the connecting plate 43 compresses the telescopic pipe 42, the pressure in the inner cavity of the telescopic pipe 42 increases, causing the one-way liquid outlet valve 44 to open, and the liquid in the inner cavity of the telescopic pipe 42 successively passes through the one-way liquid outlet valve 44, the first hose 45, the first circular pipe 46, and the nozzle 47, and finally sprays out to contact the dust for dust suppression operation. Moving the first circular pipe 46 drives the nozzle 47 and the cross plate 421 to move to adjust the position of the nozzle 47. The rotating locking bolt 422 is threadedly connected to the U-shaped sleeve 420, so that the locking bolt 422 abuts against the cross plate 421 to fix the cross plate 421;

[0069] S4. Disassembly: By operating, the moving plate 49 is pushed to move the gear column 54 and the circular plate 51 rightward, the circular plate 51 pushes the support pipe 50 and the movable pipe 59 rightward. When the movable pipe 59 contacts the movable ring 53 and stops moving rightward, the support pipe 50 continues to move rightward, causing the movable pipe 59 to pull the first connecting rope 58 to move, the first connecting rope 58 pulls the gear ring 56 to move, so that the gear ring 56 is separated from the gear column 54, the gear ring 56 drives the second limiting ring 512 to move, so that the two second limiting rings 512 are separated from the gear column 54, and moving the electric pick shovel 3 rightward drives the gear column 54 to move rightward, so that the gear column 54 is separated from the support pipe 50, and the electric pick shovel 3 is disassembled. Different specifications of electric pick shovels 3 can be replaced for use according to needs, and the drill rod can be replaced. The gear column 54 on the left side of the drill rod is meshed with the gear ring 56 for positioning and installation of the drill rod;

[0070] S5. Drilling: By controlling the elongation of the right section rod of the segmented independently controlled electric telescopic rod 48, the moving plate 49 pulls the second connecting rope 519 to move. The second connecting rope 519 pulls the moving block 514 and the sealing plate 515 to move, separating the two sealing plates 515 and exposing the tooth grooves 518. By controlling the elongation of the middle section rod of the segmented independently controlled electric telescopic rod 48, the moving plate 49 is driven to move to the right, causing the gear column 54 on the left side of the drill rod to be engaged with the tooth grooves 518. By controlling the operation of the motor 520 to drive the segmented independently controlled electric telescopic rod 48 to rotate, the segmented independently controlled electric telescopic rod 48 drives the moving plate 49, the gear column 54 and the drill rod to rotate, performing a drilling operation on the concrete, or can also drive other tools to rotate and adjust the rotation angle of the tool to facilitate the crushing of the concrete;

[0071] S6. The operator holds the handle 2 to operate the electric pick. During the operation, the electric pick body 1 drives the handle 2 to vibrate, causing the short rod 414 to drive the movable plate 415 to squeeze the liquid collecting bag 411. The liquid in the inner cavity of the liquid collecting bag 411 enters the inner cavity of the telescopic tube 42 through the connecting tube 412. The flow of the liquid cushions and dampens the movable plate 415, and the damping spring 416 cushions and dampens the movable plate 415, thereby cushioning and dampening the user's hand.
