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

[0022] See also Figure 1-Figure 5 The utility model provides a technical solution: an armature structure, including a casing, a mounting shell fixedly connected to the inner side of the casing near one end, a positioning shaft slidably connected to the inside of the mounting shell, an end of the positioning shaft away from the mounting shell is fixedly connected to the armature body, a positioning groove is provided on the outside of the positioning shaft, the positioning groove is arranged in a "J" shape, a positioning block is slidably connected to the inside of the positioning groove, the positioning block is fixedly connected to the outside of the rotating sleeve, a pushing assembly is provided at the end of the positioning shaft away from the armature body, the pushing assembly includes a spring, the spring is fixedly connected to one side of the mounting shell near the positioning shaft, and the spring is fixedly connected to the pushing block at one end near the positioning shaft.

[0023] During operation, first insert the armature body and the locating shaft into the casing, then insert the locating shaft along one end of the mounting shell, and let the locating block outside the locating shaft slide along the locating groove. When the locating block reaches the farthest point of the locating groove, release the locating shaft, and let the spring push the pushing block inside the mounting shell, so that the locating shaft enters the "J"-shaped position of the locating groove for fixation, achieving the effect of fast fixation without loosening due to shaking, solving the problem of loosening of the locating shaft caused by only using bolt connection, and improving the stability of the locating shaft fixation.

[0024] The outside of the pushing block is rotatably connected to a rotating sleeve, and the rotating sleeve abuts against the end of the positioning shaft away from the armature body. A positioning assembly is provided on the side of the pushing block away from the rotating sleeve. The positioning assembly includes a screw, which is rotatably connected to the side of the pushing block away from the rotating sleeve. The outside of the screw is rotatably connected to the inside of the mounting shell away from the position of the pushing block. The end of the screw away from the pushing block is fixedly connected to the rotating block, and the rotating block is hexagonally arranged.

[0025] When working, the rotating block rotates first, allowing the screw to rotate inside the mounting shell, thereby allowing the screw to push the pushing block and the rotating sleeve to rotate at one end of the positioning shaft. The rotating sleeve rotates outside the pushing block to prevent the pushing block from rotating together when the positioning shaft is rotated, resulting in an unstable connection between the pushing block and the spring, thereby abutting the positioning shaft to prevent the positioning shaft from detaching from the mounting shell, achieving the effect of positioning the positioning shaft, solving the problem of poor fixing effect of a single spring structure, and improving the stability of the installed positioning shaft.

[0026] The armature body is fixedly connected to a driving rod at one end away from the positioning shaft, and a mounting cover is rotatably connected to the outside of the driving rod. The mounting cover abuts against the end of the casing away from the mounting shell, and a fixing bolt is rotatably connected to the side of the mounting cover away from the casing. The fixing bolt passes through the mounting cover and is rotatably connected to one end of the casing. There are four groups of fixing bolts arranged in a circular array, and a mounting bracket is fixedly connected to the outside of the casing. There are two groups of mounting brackets arranged symmetrically.

[0027] During operation, the rotational force of the armature body can be output through the driving rod, and the driving rod will rotate inside the mounting cover. The mounting cover is fixed at one end of the casing to ensure the stability of the driving rod operation, and the fixing bolt can firmly fix the mounting cover to one end of the casing. When in use, the casing can be installed and fixed by relying on the mounting bracket. The above method realizes quick disassembly and installation, and the installation positioning shaft is more stable. It solves the problem of loosening of the armature body due to high-speed rotation caused by the bolt bracket method, and improves the stability of the fixing bolt during operation.

[0028] When working or in use, first insert the armature body and the locating shaft into the casing, then insert the locating shaft along one end of the mounting shell, let the locating block outside the locating shaft slide along the locating groove, when the locating block reaches the farthest point of the locating groove, release the locating shaft, let the spring push the push block inside the mounting shell, so that the locating shaft enters the "J"-shaped position of the locating groove for fixation, achieving the effect of fast fixation without loosening due to shaking, solving the problem of loosening of the locating shaft caused by only using bolt connection, and improving the stability of the locating shaft fixation, first rotate the rotating block, let the screw rotate inside the mounting shell, so that the screw pushes the push block and the rotating sleeve to rotate at one end of the locating shaft, and the rotating sleeve rotates outside the push block, which can prevent the push block from rotating when the positioning shaft is rotated. This causes the problem of unstable connection between the pushing block and the spring, thereby abutting the positioning shaft, preventing the positioning shaft from detaching from the inside of the mounting shell, achieving the effect of positioning the positioning shaft, solving the problem of poor fixing effect of a single spring structure, and improving the stability of the installation of the positioning shaft. The rotational force of the armature body can be output through the driving rod, and the driving rod will rotate inside the mounting cover. The mounting cover is fixed to one end of the casing to ensure the stability of the driving rod operation, and the fixing bolt can firmly fix the mounting cover at one end of the casing. When in use, the casing can be installed and fixed by relying on the mounting frame. The above method can achieve quick disassembly and installation, and the installation of the positioning shaft is more stable. The problem of loosening of the armature body due to high-speed rotation caused by the bolt bracket method is solved, and the stability of the fixing bolt during operation is improved.
