In this document, "schematic" means "serving as an example, instance, or illustration," and any illustrations, embodiments described herein as "schematic" should not be construed as a more preferred or advantageous solution.

For simplicity of the drawing, only the parts relevant to the present application are schematically shown in each drawing, and they do not represent the actual structure thereof as a product. In addition, for simplicity and ease of understanding, components having the same structure or function in some of the figures are shown only schematically or only one or more of them are labeled.

Referring to fig. 3, the present application provides an elastic locking member 30, wherein the elastic locking member 30 includes a locking portion 31 and an elastic body portion 32, wherein the locking portion 31 is configured to be inserted into a tooth slot of a gear 21 of a mower, and the elastic body portion 32 is capable of being elastically deformed to allow the locking portion 31 to withdraw from the tooth slot or insert into the tooth slot when the gear 21 rotates.

Based on the above-mentioned technical solution, when the connecting portion 33 is connected to the housing 10 of the mower, the elastic column portion 32 allows the locking portion 31 to move under elastic deformation, so that when the gear 21 rotates, the elastic body portion 32 is forced to elastically deform to allow the locking portion 31 to withdraw from the tooth slot or insert into the tooth slot. Thus, the gear 21 can be releasably locked, and with the rotation of the gear 21, the tooth grooves and tooth tops of the gear 21 collide with the locking parts 31 alternately, so that a click sound can be generated, and the click sound can remind the user that the gear 21 is rotating.

Wherein, the connecting part 33 of the elastic locking piece 30 can be detachably connected with the housing 10 of the mower, so that when the locking part 31 is severely worn, the elastic locking piece 30 can be replaced with a new one.

Referring to fig. 1 and 2, the present application further provides a mower including the elastic locking member 30, and the structure of the elastic locking member 30 and the connection and cooperation of the elastic locking member 30 and the mower will be described below according to the specific application of the elastic locking member 30 to the mower.

Specifically, the mower comprises a cutting mechanism, a shell 10, a lifting mechanism 20 and an elastic clamping piece 30, wherein the lifting mechanism 20 comprises a gear 21, and the gear 21 rotates when the lifting mechanism 20 drives the cutting mechanism to ascend or descend relative to the shell 10; the elastic locking member 30 includes a locking portion 31 and an elastic body portion 32 connected to the locking portion 31, the locking portion 31 can be inserted into a tooth slot of the gear 21, the elastic body portion 32 can be elastically deformed to allow the locking portion 31 to withdraw from the tooth slot or insert into the tooth slot when the gear 21 rotates, and the elastic locking member 30 is detachably mounted on the housing 10.

Based on the above technical solution, on one hand, when the lifting mechanism 20 does not drive the cutting mechanism to ascend or descend, the gear 21 keeps still relative to the housing 10, the locking piece 30 is inserted into the tooth slot of the gear 21, the locking piece 30 can lock the gear 21, preventing the gear 21 from rotating randomly, and playing a role in stabilizing the position of the gear 21; during the process that the lifting mechanism 20 operates to drive the cutting mechanism to ascend or descend relative to the shell 10, the gear 21 rotates, so that the clamping part 31 is pushed in the rotating direction, the elastic clamping piece 30 is forced to elastically deform, the clamping part 31 is allowed to withdraw from the tooth grooves, meanwhile, the clamping part 31 still can be abutted to the gear 21 under the elastic thrust of the elastic main body part 32, and along with the rotation of the gear 21, the tooth grooves and tooth tops of the gear 21 are alternately and correspondingly collided with the clamping part 31, so that a 'pyridazine' sound can be emitted, and the user can be reminded that the lifting mechanism 20 is in the ascending or descending process; in other words, the locking portion 31 intermittently collides with different tooth tops, and the sound of the collision can alert the user that the elevating mechanism 20 is operating. On the other hand, since the friction collision between the locking portion 31 and the gear 21 is easy to occur, and the abrasion is serious, so that the situation that the locking portion 31 is difficult to collide with the tooth top effectively occurs, therefore, the elastic locking piece 30 is detachably mounted on the housing 10, and when the abrasion of the locking portion 31 is serious, a new elastic locking piece 30 can be replaced, so that the locking portion 31 can always collide with the tooth top in the process of lifting or lowering the cutting mechanism driven by the lifting mechanism 20 relative to the housing 10, and the purpose of reminding a user that the cutting mechanism is in the lifting or lowering process is achieved.

The locking portion 31 may be tapered, and a tapered tip portion extends into the tooth slot.

In addition, the lifting mechanism 30 may further include a driving portion and a rotating shaft 22, the gear 21 is coaxially and fixedly installed on the rotating shaft 22, and the driving portion is installed at one end of the rotating shaft 22 to drive the rotating shaft 22 to rotate, so that the rotating shaft 22 can drive the gear 21 to rotate synchronously. The driving part may be an electric structure, such as a motor, or may be a manual knob. The gear 21 may be connected to the cutting mechanism by other transmission structures to drive the cutting mechanism up or down. The transmission between the gear wheel 21 and the cutting mechanism is a conventional technical means readily available to the person skilled in the art, and is not described in detail herein nor shown in the figures. The cutting mechanism may take a variety of forms and is not shown in the figures.

In one possible embodiment, referring to fig. 1 and 2, the elastic latching member 30 further includes a connection portion 33, and the elastic body portion 32 is connected between the connection portion 33 and the latching portion 31, and the connection portion 33 is detachably connected to the housing 10. Based on this technical scheme, after the connecting portion 33 is connected to the housing 10, the relative position between the connecting portion 33 and the gear is unchanged, and when the gear 21 rotates, the gear applies a pushing force to the locking portion 31 to force the elastic body portion 32 to deform, so as to drive the locking portion 31 to move, and allow the locking portion 31 to withdraw from the tooth slot. The locking portion 31 can provide stable resistance to the gear 21 in the clockwise and counterclockwise directions under the supporting action of the elastic body portion 32 when the gear 21 is stationary and not rotating, so as to facilitate the gear 21 to be kept in a stable position.

Specifically, along the radial direction of the gear 21, the extending direction of the elastic body portion 32 may be the same as the radial direction of the gear 21, the elastic body portion 32 has opposite front and rear ends in the extending direction, the locking portion 31 and the connecting portion 33 are respectively connected to the front and rear ends of the elastic body portion 32, and the connecting portion 33 is detachably connected to the housing 10. The connecting portion 33, the elastic body portion 32 and the locking portion 31 are distributed along the radial direction of the gear 21, so that the same and stable resistance force can be provided to the gear 21 in the clockwise and counterclockwise directions, which is advantageous in maintaining the gear 21 in a stable position.

There are various connection manners of the connection portion 33 and the housing 10, and in one embodiment, the connection portion 33 includes a clamping structure, and the housing 10 includes a clamping groove 11, and the clamping structure is adapted to the clamping groove 11.

Thus, the elastic body 32 passes through the escape opening 12, and one end is connected to the column in the engagement groove 11, and the other end is connected to the engagement portion 31. Since the first direction is substantially perpendicular to the upper surface of the housing 10 and the axial direction of the gear 21 is also substantially perpendicular to the upper surface of the housing, when the elastic body portion 32 is deformed by the thrust force exerted by the gear 21, the thrust force exerted by the column in the engagement groove 11 is substantially perpendicular to the first direction, so that the engagement groove 11 can be stably fitted. When the elastic locking member 30 needs to be replaced, the column body can be pulled out of the locking groove 11 along the first direction.

The cylinder can be a cylinder, and the clamping groove 11 is a circular groove correspondingly, so that the cylinder can be more conveniently inserted into the clamping groove 11.

In one example, referring to fig. 5, the protruding ribs 13 are provided on the inner wall surface of the clamping groove 11, and the protruding ribs 13 extend in the first direction. By providing the ribs 13 extending in the first direction, the friction between the cylinder and the engaging groove 11 can be increased, so that the cylinder is stably engaged in the engaging groove 11.

In one example, referring to fig. 4 and 5, the notch of the clamping groove 11 is provided with a first chamfer structure and/or the end of the cylinder is provided with a second chamfer structure. In this way, the cylinder can be conveniently inserted into the clamping groove 11 along the first direction under the guiding action of the first chamfer structure and/or the second chamfer structure.

In one possible implementation, with long-term use of the mower, the clamping structure may be pulled out of the clamping groove 11 along the first direction under the action of long-term vibration of the mower, in order to prevent the clamping structure from being pulled out of the clamping groove 11 along the first direction, a stop member may be mounted on the housing 10, and the stop member covers the notch of the clamping groove 11, so that the clamping structure may be prevented from being pulled out of the clamping groove 11.

In one example, the stop may be a decorative cover of the mower. The decorative cover may take a variety of forms, not shown in the figures of this application. That is, the decorative cover is mounted on the housing 10, and prevents the column from coming out of the clamping groove 11 along the first direction while beautifying the appearance, thereby ensuring the clamping stability of the connecting portion 33 and the housing 10.

In one possible embodiment, the elastic body portion 32 includes a main plate 321 and two side plates 322, the two side plates 322 are all perpendicularly connected to the rear surface of the main plate 321, the two side plates 322 are spaced apart, the locking portion 31 is connected to the front surface of the main plate 321 and located between the two side plates 322, and the rear ends of the two side plates 322 are both provided with connecting portions 33; when the gear 21 rotates, the main plate 321 can elastically deform to allow the locking portion 31 to withdraw from the tooth groove. Under the condition of adopting the technical scheme, the elastic main body part 32 is arranged on the shell 10 through the two connecting parts 33, has good structural stability, can provide stable support for the clamping part 31, so that the clamping part 31 can stably clamp the gear 21 when the lifting mechanism 30 is not used, and plays a role in stopping the gear 21. Wherein the extending direction of the side plate 322 may coincide with the radial direction of the gear 21.

In one embodiment, the elastic stopper 30 further includes an auxiliary support portion connected to the elastic body portion 32 or the stopper portion 31. The auxiliary supporting part can provide supporting force to keep the position of the locking part 31 stable, increase the difficulty of elastic deformation of the elastic column part 32, and further facilitate the locking part 31 to be kept at a stable position, so that the locking part 31 can stably lock the gear 21, and play a role in stopping the gear 21.

In one example, referring to fig. 1, 3 and 5, the housing 10 includes a stop surface 14 parallel to the main plate 321, the stop surface being located on the rear side of the main plate 321; the auxiliary supporting part comprises two inclined connecting plates 341 and two sliding plates 342, wherein the two inclined connecting plates 341 and the two sliding plates 342 are positioned between the two side plates 322, the front ends of the inclined connecting plates 341 are connected with the rear surface of the main plate 321, the rear ends of the inclined connecting plates 341 are connected with the sliding plates 342, the two inclined connecting plates 341 are symmetrical about the clamping part 31, and the distance between the front ends of the two inclined connecting plates 341 is smaller than the distance between the rear ends; the slide 342 is parallel to and in contact with the stop surface 14 while the gear 21 remains stationary relative to the housing 10; when the gear 21 rotates, the oblique connecting plate 341 is stressed to elastically deform relative to the main plate 321, and the sliding plate 342 slides towards the side plate along the stop surface 14.
