[0002] A lawn mower, also known as a grass cutter, is a mechanical device used for trimming and cleaning lawns, grasslands, and other vegetation. It can significantly improve the efficiency of lawn maintenance, effectively remove weeds and overgrown vegetation in the lawn, and reduce the manual labor workload.

[0003] However, when the personnel in this field actually use it, it is found that the blades of most existing lawn mowers are extremely inconvenient to install, so it takes a long time to replace them. Moreover, most of the handles are not convenient for length adjustment, which will cause certain discomfort when used by users of different heights and is not convenient for trimming some positions where it is not convenient to stand. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a lawn mower convenient for adjustment, which has the advantages of convenient replacement and installation of blades and convenient length adjustment.

[0006] Preferably, the installation mechanism includes an installation block, the installation block is fixedly connected to the output end of the motor, a clamping groove is opened inside the installation block, a clamping block is clamped inside the clamping groove, a blade is fixedly connected to the outside of the clamping block, two corresponding fixing bolts are inserted into the installation block, and the fixing bolts penetrate the clamping block and are externally threadedly connected with fixing nuts.

[0007] Preferably, a fixing screw is inserted into the installation block, and the fixing screw is threadedly connected into the clamping block.

[0008] Preferably, the shapes of the clamping groove and the clamping block are both set to be convex, and the clamping block is wedged in the clamping groove.

[0009] Preferably, the adjusting mechanism includes a screw rod, the screw rod is fixedly connected to the outside of the fixed shell, a sleeve is sleeved on the outside of the screw rod, a first handle is fixedly sleeved on the outside of the sleeve, a second handle is fixedly connected to the top of the sleeve, a threaded ring is threadedly connected to the outside of the screw rod, a slider is fixedly connected to the outside of the threaded ring, a chute is opened at one end of the sleeve, and the threaded ring is slidably connected in the chute through the slider.

[0010] Preferably, two correspondingly distributed limiting grooves are opened in the sleeve, limiting blocks are fixedly connected to both sides of the screw rod, and the limiting blocks are slidably connected in the limiting grooves.

[0011] Preferably, a turning handle is fixedly connected to the outside of the threaded ring, and the turning handle is made of stainless steel.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. By inserting the clamping block fixedly connected to the outside of the blade into the clamping groove, since both the clamping block and the clamping groove are set to be convex, it will be more tightly and stably fixed during insertion. Then, insert the fixing screw into the mounting block, and then thread it into the clamping block to complete the preliminary fixing and limiting. Then, insert two fixing bolts into the mounting block and penetrate the clamping block, and then thread the fixing nut onto the outside of the fixing bolt to complete the secondary fixing. Through this structure, the blade can be quickly replaced, which is more convenient for users.

[0014] 2. By rotating the turning handle, the fixedly connected threaded ring is then driven to rotate. At this time, the slider fixedly connected to the outside of the threaded ring slides in the chute, making the rotation smoother. Then, it drives the screw rod connected by threads to move outwards. When the screw rod moves, the limiting blocks fixedly connected to both sides slide in the limiting grooves, making the movement smoother and more stable. At this time, the length has been adjusted. Rotating in the reverse direction can shorten it. When adjusted to a longer length, it can conveniently trim some positions where it is inconvenient for the staff to stand, making the trimming work more convenient and effectively improving the comfort of the staff.
