Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, 2 and 3, the present invention discloses a handle assembly 100, which includes a stationary handle 10, a movable handle 20 mounted on the stationary handle 10, a micro switch 30, a trigger 40 engaged with the micro switch 30, and a first elastic element 50.
Referring to fig. 1, 2, 3 and 4, the stationary handle 10 includes a first housing 11 and a second housing 12 coupled to the first housing 11. The first housing 11 and the second housing 12 jointly enclose to form an accommodating cavity 13 for accommodating the micro switch 30, the trigger 40 and the first elastic element 50. The static handle 10 is further provided with a mounting groove 14 communicated with the accommodating cavity 13. The movable handle 20 is movably mounted in the mounting groove 14 and is configured to: the movable handle 20 is partially located in the accommodating cavity 13 and partially located outside the accommodating cavity 13. The movable handle 20 can move relatively to the stationary handle 10. The microswitch 30 is fixedly arranged on the static handle 10. The trigger 40 is configured to cooperate with the microswitch 30 to trigger the microswitch 30. The first elastic element 50 is disposed between the trigger 40 and the movable handle 20. When the movable handle 20 is pressed and the movable handle 20 moves towards the stationary handle 10, the movable handle 20 applies an acting force to the first elastic element 50, so that the trigger 40 moves under the action of the first elastic element 50 and abuts against the microswitch 30, and the microswitch 30 is triggered. Because the movable handle 20 indirectly pushes the trigger 40 to move and abut against the microswitch 30 through the first elastic element 50, when the force applied by the user to the movable handle 20 is larger, the redundant acting force can be absorbed by the first elastic element 50, so that the trigger 40 is effectively ensured not to over-press the microswitch 30, the microswitch 30 is protected, and the service life of the microswitch 30 is prolonged.
Specifically, referring to fig. 6, 7 and 3, the trigger 40 is pivotally mounted on the first housing 11 through a first pivot 401. The trigger 40 includes an arm 41 and a holding portion 42. The first pivot 401 is disposed at an end of the arm 41 away from the holding portion 42. The arm 41 is further provided with a second pivot 402 and a receiving groove 411. The first pivot 401 and the second pivot 402 are located on the same side of the arm 41. In this embodiment, the first pivot 401 and the second pivot 402 are integrated with the trigger 40, but in other embodiments, the first pivot 401 and the second pivot 402 may be separated from the trigger 40, that is: the first pivot 401, the second pivot 402 and the trigger 40 are independent parts. The accommodating groove 411 is used for accommodating the first elastic element 50. A smooth guiding surface 421 is disposed on a side of the abutting portion 42 facing the micro switch 30 to reduce resistance force applied when the abutting portion 42 abuts the micro switch 30. The first elastic element 50 is a spring piece and is pivotally mounted on the second pivot 402. The first elastic element 50 includes a first contact portion 51 cooperating with the trigger 40 and a second contact portion 52 cooperating with the movable handle 20. When the movable handle 20 is pushed to trigger the microswitch 30, the first contact part 51 abuts against the trigger 40, and the second contact part 52 abuts against the movable handle 20. When the movable handle 20 is released, namely: when the movable handle 20 is in the initial state, there is a gap between the first contact portion 51 and the trigger 40. The arrangement is to ensure that the first elastic element 50 is in a free state, and no elastic force is applied to the trigger 40, so as to ensure that the trigger 40 is in an unstressed free state, and thus the micro switch 30 is not triggered by mistake. Of course, it is understood that in other embodiments, it may be configured as follows: when the movable handle 20 is in the initial state, there is no gap between the first contact portion 51 and the trigger 40. In this way, when the movable handle 20 is in the initial state, the first contact portion 51 elastically abuts against the trigger 40, and at this time, the acting force applied by the first contact portion 51 to the trigger 40 is smaller than the acting force applied by the micro switch 30 to the trigger 40, and the micro switch 30 is not triggered; when the movable handle 20 is pressed, the first contact portion 51 exerts a larger force on the trigger 40 than the micro switch 30 exerts on the trigger 40, and the micro switch 30 is triggered. Although the first elastic element 50 is pivotally mounted on the trigger 40 in the present embodiment, in other embodiments, the trigger 40 may be configured as: the first housing 11 is pivotally mounted or fixedly mounted on the movable handle 20.
Further, referring to fig. 2, 3 and 5, the mounting groove 14 and the movable handle 20 are C-shaped and symmetrical about a first axis of symmetry AA. The micro switch 30 and the first pivot 401 are respectively located at two sides of the first symmetry axis AA, and the first pivot 401 and the second pivot 402 are located at the same side of the first symmetry axis AA. The second contact portion 52 has an included angle α with the first axis of symmetry AA. When the first elastic element 50 is in a free state, the included angle α is between 70 degrees and 110 degrees. The arrangement is such that when a user applies a force in any one of the directions a, B, C shown in fig. 1, the microswitch 30 can be caused to be triggered. Specifically, referring to fig. 8, when a user applies a force in a direction a, the movable handle 20 moves to the left and moves towards the stationary handle 10 in the direction a, and the movable handle 20 rotates around the left end as an axis, so that the movable handle 20 rotates counterclockwise; the top of the movable handle 20 abuts against the first elastic element 50, so that the first elastic element 50 is elastically deformed, thereby triggering the microswitch 30. Referring to fig. 9, when a user applies a force in a direction B, the movable handle 20 moves towards the stationary handle 10 in the direction B, and at this time, the left side of the movable handle 20 abuts against the left second elastic element 60, and the right side abuts against the right second elastic element 60, so that the left and right second elastic elements 60 are elastically deformed; the top of the movable handle 20 abuts against the first elastic element 50, so that the first elastic element 50 is elastically deformed, thereby triggering the microswitch 30. Referring to fig. 10, when a user applies a force in a direction C, the movable handle 20 moves to the right and moves toward the stationary handle 10 in the direction C, and the movable handle 20 rotates around a right end as an axis, so that the movable handle 20 rotates clockwise; the top of the movable handle 20 abuts against the first elastic element 50, so that the first elastic element 50 is elastically deformed, thereby triggering the microswitch 30.
In this embodiment, the trigger 40 is pivotally mounted on the first housing 11, but in other embodiments, the trigger 40 may also be pivotally mounted on the movable handle 20. When the trigger 40 is pivotally mounted on the movable handle 20, the first elastic element 50 may be configured to be mounted on the trigger 40, or may be configured to be mounted on the movable handle 20.
Referring to fig. 3 and 4, preferably, the handle assembly 100 is further provided with a second elastic element 60 mounted on the stationary handle 10 and located in the receiving cavity 13. The second elastic element 60 is provided with a holding portion 61, a positioning groove 62 and an elastic abutting end 63. The first housing 11 is provided with a holding groove 111 cooperating with the holding part 61 and a positioning column 112 cooperating with the positioning groove 62, so that the second elastic element 60 is fixed on the first housing 11 by cooperation of the holding part 61 and the holding groove 111 and cooperation of the positioning groove 62 and the positioning column 112. The elastic abutting end 63 elastically abuts against the movable handle 20. When the movable handle 20 is pressed, the second elastic element 60 is elastically deformed by the movable handle 20; when the movable handle 20 is released, the movable handle 20 is restored by the second elastic member 60.
Compared with the prior art, the handle assembly 100 of the present invention triggers the micro switch 30 through the trigger 40, and absorbs the excessive acting force through the first elastic element 50, so as to effectively ensure that the trigger 40 does not over-press the micro switch 30, thereby protecting the micro switch 30 and prolonging the service life of the micro switch 30.
Referring to fig. 11, the present invention further discloses a pruning machine 200, which includes an operating rod 201, a pruning mechanism 202 installed at one end of the operating rod 201, a battery pack 203 installed at the other end, and the handle assembly 100 installed on the operating rod 201.
Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the present invention.
