The slider 3325 is disposed at an opening of the side wall 3324 and is movable in a direction parallel to the side wall 3324, for example. In this embodiment, limit switch 3326 is moved in a direction perpendicular to side wall 3324 to rotationally limit trigger 340. When limit switch 3326 is pressed into the interior of sidewall 3324, trigger 340 is secured and trigger 340 is disabled. The slide 3325 moves in a direction parallel to the side walls 3324 to control the direction of rotation of the earth auger.

Referring to fig. 7, fig. 7 is a schematic view of a trigger structure according to an embodiment of the present application. In one embodiment of the present application, the trigger 340 may include a receiver 341, a stop 342, a push arm 343, a pivot 344, a spring return 3441, a rotating arm 345, and a trigger head 346.

The supporting portion 341 is used to contact with the operator, and when the operator presses the supporting portion 341, the push arm 343 and the rotating arm rotate about the pivot 344. Spring return element 3441 is now in a compressed state such that trigger head 346 is moved a distance to facilitate the conduction of the switch. When the limit switch 3326 is pushed into the interior of the side wall 3324, the limit switch 3326 contacts the limit portion 342 and limits the movement of the limit portion 342 around the pivot 344. At this point the trigger 340 is fixed and the trigger 340 is not operational.

Referring to fig. 8, fig. 8 is a cross-sectional view of a handle structure according to an embodiment of the present application.

When limit switch 3326 is pressed into the interior of sidewall 3324, trigger 340 is secured and trigger 340 is disabled. When the limit switch 3326 is ejected to the outside of the side wall 3324, the receiving portion 341 of the trigger 340 is pressed. The push arm 343 and the rotary arm 345 of the trigger 340 rotate about the pivot 344, at which time the trigger head 346 moves a distance and contacts the first contact blade 351 of the activation switch 350. The first contact 351 activates the start switch 350, thereby bringing the earth auger into operation. At this time, the spring return member 3441 is elastically deformed, and the start switch 350 controls the operation of the motor assembly 400. When the start switch 350 directly transmits a start signal to the motor assembly 400, the start switch 350 directly controls the motor assembly 400 to operate. When the start switch 350 sends a start signal to the control module 600, and the control module 600 controls the motor module 400 to operate, the start switch 350 indirectly controls the motor module 400 to operate. When the retainer 341 is released, the trigger 340 is reset by the spring reset element 3441.

Referring to fig. 8, in an embodiment of the present application, the sliding block 3325 moves in a direction parallel to the side wall 3324 in the sliding rail 33251 to control the rotation direction of the earth auger. The sliding block 3325 is slidably mounted on the sliding rail 33251, and the reversing switch 360 is matched with the sliding block 3325. In this embodiment, the reversing switch 360 may be located above the sliding direction of the slider 3325. When the user pushes the slider 3325 to slide along the sliding rail 33251, the slider 3325 abuts against the second contact piece 361 of the reversing switch 360 and triggers the reversing switch 360 to work through the second contact piece 361. At this time, the reversing switch 360 sends a reversing signal to the motor assembly 400 to control the motor assembly 400 to rotate forward or reverse. The second handle 332 guides the hand of the operator to be in a gripping state by the cooperation of the start switch 350 and the change-over switch 360 and the position of the two on the handle housing 3321, so that the operator can cope with abrupt large moment changes at any time, and the thumb of the trigger bearing portion 341 is easily separated.

Referring to fig. 11, fig. 11 is a schematic diagram of a control component in an embodiment of the present application. In an embodiment of the present application, control assembly 600 may include a controller 610 and a gyro sensor 620. In this embodiment, the transmission assembly 500 is disposed on the connection base 200, and the motor assembly 400 is connected to the transmission assembly 500.

The monitoring parameter value of the ground auger can be changed by adjusting the control button 1501 according to the type, the texture, the operation condition and the like of the ground, so that the ground auger is convenient to adapt to the safety monitoring and early warning of complex terrains and under different operation conditions. In some embodiments of the present application, different monitoring mode status of the earth boring machine may be displayed by a single indicator light 1502, or may be displayed by illuminating the number of indicator lights

In summary, the present application proposes an earth auger, which monitors a dangerous state in real time when foreign matters such as roots or stones are about to be unbalanced or blocked during the earth auger boring, and transmits dangerous information to an operator and controls emergency stop. Therefore, accidents can be effectively prevented, and the operation safety is improved.
