[0003] The throttle adjustment assembly includes: a throttle adjustment lever, a throttle adjustment handle, a throttle cable connection part, and a throttle locking assembly. The throttle locking assembly includes: a throttle limit card plate fixedly connected to the push rod, and a plurality of throttle limit grooves are evenly spaced along the circumferential direction on the end surface of the throttle limit card plate; a throttle limit protrusion is provided at the end of the throttle adjustment lever opposite to the throttle adjustment handle, and the middle part of the throttle adjustment lever is rotatably connected to the throttle limit card plate through a first mounting shaft.
[0004] The above-mentioned product allows the user to push / pull the throttle adjustment handle to rotate the throttle adjustment lever, so that the throttle limit protrusion slides out of one throttle limit groove and snaps into another throttle limit groove, thereby adjusting and locking the engine speed. However, the limiting effect of the throttle limit protrusion and the throttle limit groove is not good. When the throttle adjustment lever is subjected to external force, it is easy for the limit protrusion to slide out of the throttle limit groove, thereby rotating the throttle cable connection part, causing the engine throttle size to change, so that the lawn mower cannot achieve the expected weeding effect.

[0008] By adopting the above technical solution, when the two driving members are not used to drive the first slider and the second slider to move, the first pawl is meshed with the first ratchet wheel, and the second pawl is meshed with the second ratchet wheel under the action of the two elastic members. Therefore, except for using the driving member to move the first slider and the second slider and release the cooperation between the first pawl and the first ratchet wheel, and the second pawl and the second ratchet wheel, other external forces are difficult to cause the installation shaft and the throttle cable rod to rotate under force, so that the throttle output is stable when the lawn mower is working, and the weeding effect is stable when the lawn mower is working. When the throttle of the engine needs to be increased, the first slider is moved toward the installation shaft by using the driving part to release the cooperation between the first pawl and the first ratchet wheel, and then the throttle adjustment rod is pushed clockwise to drive the throttle cable rod to rotate clockwise through the connecting column to increase the engine speed of the lawn mower. When the throttle of the engine needs to be reduced, the second slider is moved toward the installation shaft by using the driving part to release the cooperation between the second pawl and the second ratchet wheel, and then the throttle adjustment rod is pushed counterclockwise to drive the throttle cable rod to rotate counterclockwise through the connecting column to reduce the engine speed of the lawn mower.
[0009] Preferably, the elastic member is a spring, and two springs are respectively located on both sides of the installation shaft, and the ends of the two springs that are far away from each other respectively abut against the first slider and the second slider, and the ends of the two springs that are close to each other both abut against the installation shaft.

At this time, the side of the first inclined groove close to the mounting shaft is located on the movement path of the first lever. Therefore, when the first lever rotates, the first inclined surface will push the first slider to move close to the mounting shaft, thereby releasing the cooperation between the first pawl and the first ratchet wheel and causing the force of the spring that contacts the first slider to be compressed, so that the throttle adjustment rod, the connecting column, the mounting shaft, and the guide rail can rotate clockwise, and the throttle cable rod is driven to rotate clockwise through the connecting column, thereby increasing the engine speed of the lawn mower, achieving the effect of increasing the engine throttle. After the engine throttle is adjusted to the appropriate power, the operator no longer pushes the throttle adjustment rod, and the spring that contacts the first slider rebounds, causing the first pawl to move toward the first ratchet wheel, and finally causing the first pawl to mesh with the first ratchet wheel, completing the locking of the throttle size. When the throttle of the engine needs to be reduced, the throttle adjustment lever is pushed counterclockwise, and the first lever and the second lever will also move counterclockwise. The side of the second inclined groove close to the mounting shaft is located on the movement path of the second lever. Therefore, when the second lever rotates, the second inclined surface will push the second slider to move close to the mounting shaft, thereby releasing the cooperation between the second pawl and the second ratchet wheel and causing the force of the spring that contacts the second slider to be compressed, so that the throttle adjustment lever, the connecting column, the mounting shaft, and the guide rail can rotate counterclockwise, and the throttle cable rod is driven to rotate clockwise through the connecting column, thereby reducing the engine speed of the lawn mower. After the engine throttle is adjusted to the appropriate power, the operator no longer pushes the throttle adjustment lever, and the spring that contacts the second slider rebounds, causing the second pawl to move toward the second ratchet wheel, and finally causing the second pawl to mesh with the second ratchet wheel, completing the locking of the throttle size.

The first mounting seat 13, the second ratchet 17, and the cover 25 are connected by four bolts threadedly connected to the threaded holes 81 of the three connecting blocks 8 on the same side.
[0056] The steps for adjusting the throttle size of the lawn mower in this application are as follows:
[0057] When it is necessary to increase the throttle of the engine, the throttle adjustment rod 14 is pushed clockwise, and the first lever 71 and the second lever 72 will also move clockwise. At this time, the side of the first inclined slot 42 close to the mounting shaft 2 is located on the movement path of the first lever 71. Therefore, when the first lever 71 rotates, the first inclined surface will push the first slider 4 to move close to the mounting shaft 2, thereby releasing the cooperation between the first pawl 41 and the first ratchet 16 and causing the spring 61 that contacts the first slider 4 to be compressed, so that the throttle adjustment rod 14, the connecting column 22, the mounting shaft 2, and the guide rail 3 can rotate clockwise, and drive the throttle cable rod 15 to rotate clockwise through the connecting column 22, so that the throttle cable increases the engine speed of the lawn mower, thereby achieving the effect of increasing the engine throttle. After the engine throttle is adjusted to a suitable power, the operator no longer pushes the throttle adjustment rod 14, and the spring 61 that contacts the first slider 4 rebounds, causing the first pawl 41 to move toward the first ratchet 16, and finally causing the first pawl 41 to mesh with the first ratchet 16, completing the locking of the throttle.
[0058] When it is necessary to reduce the throttle of the engine, the throttle adjusting rod 14 is pushed counterclockwise, and the first lever 71 and the second lever 72 will also move counterclockwise. The side of the second inclined slot 52 close to the mounting shaft 2 is located on the movement path of the second lever 72. Therefore, when the second lever 72 rotates, the second inclined surface will push the second slider 5 to move close to the mounting shaft 2, thereby releasing the cooperation between the second pawl 51 and the second ratchet 17 and causing the spring 61 that contacts the second slider 5 to be compressed, so that the throttle adjusting rod 14, the connecting column 22, the mounting shaft 2, and the guide rail 3 can rotate counterclockwise, and drive the throttle cable rod 15 to rotate clockwise through the connecting column 22 and pull the throttle cable to reduce the engine speed of the lawn mower. After the engine throttle is adjusted to a suitable power, the operator no longer pushes the throttle adjusting rod 14, and the spring 61 that contacts the second slider 5 rebounds to cause the second pawl 51 to move toward the second ratchet 17, and finally causes the second pawl 51 to mesh with the second ratchet 17 to complete the throttle locking.
