[0031] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0032] Example 1: A lawn mower throttle positioning device, see Figures 1 to 3;

[0033] It includes a sleeve handle 1, an unlocking key 2, a throttle key 3, a connecting arm 5 and a limit handle 4;

[0034] The sleeve handle 1 is used to connect the throttle trigger of the lawn mower; the throttle trigger of the lawn mower corresponds to the throttle button 3, and the throttle button 3 is pressed into the sleeve handle 1 to contact the throttle trigger of the lawn mower and start the lawn mower; the unlocking button 2 is arranged at the top of the sleeve handle 1; wherein the unlocking button 2 is rotatably connected to the inner cavity wall of the top of the sleeve handle 1 through a rotating shaft; the throttle button 3 is arranged at the bottom of the sleeve handle 1; wherein the throttle button 3 is rotatably connected to the inner cavity wall of the bottom of the sleeve handle 1 through a rotating shaft; one end of the connecting arm 5 is connected to the rotating shaft of the throttle button 3 The other end of the connecting arm 5 abuts against the block 202 on the inner side of the unlocking key 2; the other end of the connecting arm 5 abuts against the block 202 at the inner side of the unlocking key 2 in an arc shape, making the opening smoother; the inner end of the unlocking key 2 is provided with a protruding hook 201, and the top connecting side of the throttle key 3 is provided with a clamping block 301, which clamps and cooperates with the protruding hook 201; one end of the limiting handle 4 is connected to the outer end of the rotating shaft of the throttle key 3; the other end of the connecting arm 5 is provided with anti-skid grooves 401 on both sides, so that the anti-skid grooves 401 are not easily slipped when pushed by fingers. The outer opening of the anti-skid groove 401 is in an eight-shaped shape, and the outer opening wall of the anti-skid groove 401 is curved, making it easier for the flesh of the finger to fit in and preventing discomfort after insertion.

[0035] The utility model is provided with a sleeve handle 1, an unlocking key 2, a throttle key 3, a connecting arm 5 and a limiting handle 4. The limiting handle 4 is pushed to push the unlocking key 2 away, so that the throttle key 3 is embedded in the sleeve handle 1 and contacts the throttle trigger of the lawn mower to start the lawn mower, and the throttle key 3 is kept embedded, thereby solving the problem that the throttle of the lawn mower needs to be pressed continuously, which is quite troublesome.

[0036] Example 2: A lawn mower throttle positioning device, see Figure 4 ;

[0037] An arc-shaped strip 203 is provided on the top inner end of the unlocking button 2 , and an arc-shaped slideway 101 is provided on the inner top wall of one end of the sleeve handle 1 , and the top of the arc-shaped strip 203 is in sliding engagement with the arc-shaped slideway 101 .

[0038] The present invention provides the arc strip 203 and the arc slide 101 , so that when the unlocking key 2 is pressed, the rotation of the unlocking key 2 drives the top of the arc strip 203 to slide along the arc slide 101 , so that the rotation of the unlocking key 2 remains stable.

[0039] Working Principle: When using the device of the present invention, push the stop handle 4. One end of the stop handle 4 drives the connecting arm 5 and the throttle button 3 to rotate together. The other end of the connecting arm 5 pushes away the abutment 202, allowing the unlock button 2 to rotate and embed into the sleeve handle 1. The rotation of the unlock button 2 drives the top of the curved bar 203 to slide along the curved slide 101, causing the inner end of the unlock button 2 to rotate upward, separating the abutment 301 from the protruding hook 201, allowing the throttle button 3 to be smoothly pressed into the sleeve handle 1. Once the stop handle 4 is fully pushed, the outer end of the protruding hook 201 abuts against the inner side of the top of the throttle button 3, forcing the throttle button 3 into the sleeve handle 1. Once the throttle button 3 is embedded in the sleeve handle 1, it contacts the throttle trigger of the lawn mower, starting the lawn mower and maintaining the throttle button 3 in the embedded state. To stop the mower, press the unlock button 2, causing the protruding hook 201 to tilt up, pushing the stop handle 4 back to reset the position.

[0040] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
