[0002] A lawn mower is a mechanical device used to cut long grass on a lawn or meadow. It usually consists of a rotating blade or cutting system, driven by electricity or an internal combustion engine, which enables it to cut grass quickly and efficiently.

[0003] Most lawn mowers are equipped with a handle to operate and control the direction and speed of the mower. The handle is usually designed to be comfortable and practical, allowing the user to easily hold and control the operation of the mower. Through the handle, the user can push or guide the mower to move along the area to be mowed, and can also control the speed and direction of the mower to ensure that the lawn is mowed evenly. Therefore, the handle is an important part of the mower and is very critical for the user.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1: This embodiment is intended to solve the problem that the handle is usually installed on the upper side of the connecting rod of the lawn mower by multiple bolts, but whether it is installed or removed, it is necessary to use a wrench to install and remove the bolts before the handle can be installed and removed, which is inconvenient. Please refer to Figure 1-Figure 4 A garden mechanical quick-release structure includes a handle body 110 and a connecting rod 111 installed on the bottom side of the handle body 110. A connecting pipe 112 is integrally connected to the bottom side of the handle body 110. The connecting pipe 112 is plugged into the connecting rod 111. A fixing assembly 120 fixed to the connecting pipe 112 is installed inside the connecting rod 111. A connecting ring 113 for pushing the fixing assembly 120 is installed outside the connecting rod 111. An external thread section 130 is provided on the side of the connecting rod 111. An internal thread section 131 is provided inside the connecting ring 113. The connecting rod 111 is threadedly connected to the connecting ring 113. A support rod 114 is installed inside the connecting rod 111.

[0023] When the connecting tube 112 is inserted into the connecting rod 111, the supporting rod 114 is inserted into the connecting tube 112, and a connecting groove 140 is installed on the side of the connecting rod 111. The fixing assembly 120 includes a fixing rod 121 movably installed inside the connecting groove 140, and a first groove 122 opened on the side of the connecting groove 140, and a pushing spring 123 installed inside the first groove 122. A connecting block 124 is symmetrically installed on the side of the fixing rod 121. The connecting block 124 is slidably arranged on the side of the first groove 122, and the end of the pushing spring 123 is connected to the connecting block 124.

[0024] A round hole 150 is formed on the surface of the connecting tube 112 for the fixing rod 121 to pass through, and a snap-fit ​​groove 151 is formed on the side of the supporting rod 114 . When the connecting tube 112 and the connecting rod 111 are plugged in, the round hole 150 and the snap-fit ​​groove 151 are at the same level.

[0025] When the external thread section 130 is connected to the internal thread section 131 , the connecting ring 113 pushes the fixing rod 121 to move, so that the fixing rod 121 passes through the circular hole 150 and reaches the inside of the engaging groove 151 , thereby fixing the connecting rod 111 and the connecting tube 112 through the displacement of the fixing rod 121 .

[0026] In this embodiment: when in use, the connecting rod 111 and the connecting tube 112 are plugged together and the connecting ring 113 is rotated at the same time, so that the external thread section 130 and the internal thread section 131 on the inner wall of the connecting ring 113 are docked. Therefore, during the docking process of the external thread section 130 and the internal thread section 131, the inner wall of the connecting ring 113 contacts the fixing rod 121, so that the fixing rod 121 is docked into the inside of the engaging groove 151, thereby fixing the connecting rod 111 and the connecting tube 112. This solution has a simple structure and is easy to operate. The connecting rod 111 and the connecting tube 112 are fixed by rotating the connecting ring 113. At the same time, the connecting rod 111 and the connecting tube 112 are unfixed during the rotation of the connecting ring 113, thereby facilitating disassembly.

[0027] Embodiment 2: This embodiment is intended to promote the solution of the problem of further strengthening the fixation of the connecting rod and the connecting tube to make the handle body more stable. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 4 A gas storage tank 160 is symmetrically provided inside the support rod 114, and the gas storage tank 160 is communicated with the engaging groove 151. A first piston block 161 and a second piston block 162 are respectively inserted and slidably fitted at both ends of the gas storage tank 160. A protrusion 163 is symmetrically installed inside the gas storage tank 160, a first spring 164 is installed between the protrusion 163 and the first piston block 161, and a second spring 165 is installed between the second piston block 162 and the gas storage tank 160.

[0028] The inner wall of the connecting pipe 112 is provided with a docking groove 170 that engages with the end of the second piston block 162. The bottom side of the first piston block 161 is set as an inclined surface. When the fixing rod 121 reaches the inside of the engaging groove 151, the fixing rod 121 pushes the first piston block 161, so that the gas inside the gas storage tank 160 pushes the second piston block 162, so that the end of the second piston block 162 engages with the docking groove 170.

[0029] In this embodiment: in the process of getting the fixed rod 121 to dock with the inside of the engaging groove 151, the fixed rod 121 contacts the first piston block 161, so that the first piston block 161 slides inside the gas storage tank 160, so that the first piston block 161 uses gas to push the second piston block 162 during the sliding process, so that the end of the second piston block 162 is inserted into the docking groove 170, thereby strengthening the connection between the connecting rod 111 and the connecting tube 112. This solution has a simple structure and is easy to operate. Through the cooperation of the fixed rod 121, the first piston block 161 and the gas storage tank 160, the insertion of the connecting rod 111 and the connecting tube 112 is further strengthened.
