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.

[0016] Example 1

[0017] See also Figure 1 and Figure 2 , which is the first embodiment of the utility model, and this embodiment provides a technical solution: a gasoline engine wire pull disc, comprising a pull disc cover 1 and a pull seat 2 arranged on the left side of the pull disc cover 1, a T-shaped handle 3 is fixed to the top of the pull seat 2, a support plate 4 is also fixed to the surface of the pull disc cover 1 relative to the top of the T-shaped handle 3, and a limiting structure is provided between the T-shaped handle 3 and the support plate 4;

[0018] The limiting structure includes an inner groove 51, a spring 52, an inner slide seat 53, a side groove 54, a side slide plate 55 and a limiting clamping rod 56. The inner groove 51 is arranged inside the T-shaped handle 3, and the side groove 54 is arranged to one side of the inner groove 51. The inner slide seat 53 is movably installed in the inner groove 51 through the spring 52. A side slide plate 55 is welded and fixed to one side of the inner slide seat 53, and the side slide plate 55 is slidably located in the side groove 54. The limiting clamping rod 56 is welded and fixed to the top of the side slide plate 55. A limiting clamping hole 57 corresponding to the limiting clamping rod 56 is arranged on the surface of the support plate 4. The top end of the limiting clamping rod 56 penetrates into the limiting clamping hole 57, which can play a role in stabilizing the limiting position of the T-shaped handle 3. Even if the T-shaped handle 3 is accidentally touched or released by an external object in the later stage, the T-shaped handle 3 can be prevented from being accidentally touched or released by an external object in the later stage. Even if the T-shaped handle 3 is accidentally entangled by external objects, it will not be accidentally pulled under the limiting action of the limiting clamping rod 56, thereby ensuring the stability of the entire gasoline engine wire pull disc. A pressing block 58 is fixed to the top of the inner sliding seat 53, and the top of the pressing block 58 penetrates to the top of the T-shaped handle 3. If the operator wants to pull the T-shaped handle 3 to start the gasoline engine in the later stage, he only needs to hold the T-shaped handle 3 and press the pressing block 58 with his fingers, so that the inner sliding seat 53 moves downward to compress the spring 52, and the side slide plate 55 moves downward with the limiting clamping rod 56, and finally the top of the limiting clamping rod 56 moves out of the limiting clamping hole 57, so that the limit on the T-shaped handle 3 can be released, and the T-shaped handle 3 can be pulled normally at this time.

[0019] Among them, a cylindrical bottom groove is opened on the bottom surface of the inner slide seat 53, and the top end of the spring 52 is inserted into the cylindrical bottom groove to achieve stable installation of the spring 52 and prevent the spring 52 from shifting during subsequent use. The bottom end of the spring 52 is fixed to the bottom inner wall of the inner groove 51 to further ensure the installation stability of the spring 52.

[0020] Among them, the top inner wall of the inner groove 51 is provided with a top hole A which is connected to the top surface of the T-shaped handle 3, and the top hole A corresponds to the pressing block 58, so that the pressing block 58 can pass through smoothly. The top inner wall of the side groove 54 is provided with a top hole B which is connected to the top surface of the T-shaped handle 3, and the top hole B corresponds to the limiting rod 56, so that the limiting rod 56 can pass through smoothly.

[0021] Example 2

[0022] See also Figures 1 to 3 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that a sealing structure can be provided to prevent foreign objects from accidentally entering the limit card hole 57.

[0023] Specifically, the limiting structure also includes a sealing structure, which is arranged on the top of the support plate 4. The sealing structure includes a sealing gasket 59 rotatably installed on the top surface of the support plate 4, and the sealing gasket 59 covers the limiting card hole 57 to prevent foreign objects from accidentally entering the limiting card hole 57. The bottom surface of the sealing gasket 59 is provided with an integrated circular protrusion 591, both of which are made of rubber material and will undergo elastic deformation when squeezed. The circular protrusion 591 is embedded in the limiting card hole 57 to limit the sealing gasket 59 and prevent the sealing gasket 59 from spinning. If the sealing gasket 59 is to be rotated and removed later, it only needs to be pushed forcefully to make the circular protrusion 591 elastically deformed by being squeezed and finally squeezed out of the limiting card hole 57, and the sealing gasket 59 can be smoothly rotated and removed from the top of the limiting card hole 57, thereby facilitating the inspection, maintenance or cleaning of the limiting card hole 57.
