[0027] By installing convenient assembly tool 3 on the device, when using the device, several parts can be assembled by convenient assembly tool 3, and the fixing work of bolts and other tools can be avoided, and the work of fixed locking can be completed manually and conveniently.

[0028] Assembly main part component 1 includes main body 101, the periphery outside of main body 101 is connected with protective silica gel 102, and the rear side of main body 101 is installed with assembly partition plate 103, the middle of assembly partition plate 103 is provided with assembly hole 104, main body 101 is the core support structure of clutch, and the assembly cavity 1012 in the inside is used for installing centrifugal block 1013 and damping spring 1014. Protective silica gel 102 plays a damping and protection role, and assembly partition plate 103 and assembly hole 104 are used for fixing and limiting other components.

[0029] Assembly edge clamp component 2 includes edge clamp plate 201, a week of edge clamp plate 201 is provided with fixed screw hole 202 and limiting assembly hole 203, fixed screw hole 202 and limiting assembly hole 203 are distributed in intersection mode, and edge clamp plate 201 is connected with convenient assembly tool 3 through fixed screw hole 202 and limiting assembly hole 203, to ensure the stability and reliability of clutch when rotating at high speed.

[0030] The limiting cavity 306 is arranged inside the limiting protrusion 307.

[0031] The main body 101 comprises an assembling ring 1011, one side of the assembling ring 1011 is provided with an assembling cavity 1012, the inside of the assembling cavity 1012 is limitedly installed with a limiting block 1013, a damping spring 1014 is installed between the two limiting blocks 1013, and the middle of the limiting block 1013 penetrates through the limiting column 302.

[0032] One side of the limiting block 1013 is provided with a limiting installation hole 10131, and the top and bottom of the limiting installation hole 10131 are connected with silica gel pads 10132.

[0033] When in use, firstly, the front side of the assembly main body assembly 1 is installed with the assembly edge clamp assembly 2, and at the same time, the fixing installation work is carried out through the convenient assembly tool 3, that is, the overall installation work can be completed, and the installation through the convenient assembly tool 3 can be more convenient, avoiding the traditional fixing of the bolt by means of tools, so as to realize the part plate assembly work. When installing the limiting position, firstly, the assembly main body assembly 1 and the assembly edge clamp assembly 2 are combined, and the assembly hole 104 of the main body 101 corresponds to the limiting installation hole 10131, so that the limiting protrusion 307 can be extruded to the inside of the limiting base 303 until it is attached. By means of pressing the supporting spring 305 inside, the telescopic rod 304 is retracted in the temporal part of the limiting cavity 306, so that the limiting protrusion 307 and the limiting base 303 pass through the hole position, and in the process of passing through, different position rotation adjustments can be carried out according to different penetration directions, and the limiting column 302 is under the action of the limiting plate 301, and timely limiting does not affect the working effect of the limiting fixation. Through the above, the limiting fixation working effect can be realized. When the clutch is at rest or low-speed rotation, the centrifugal block or limiting block 1013 is kept in the state of inward retraction under the action of the damping spring 1014, at this time, the centrifugal block is not in contact with the transmission component such as the outer ring or the friction surface, and the clutch is in the separated state, and the power cannot be transmitted. When the clutch speed gradually increases, the centrifugal force increases. When the speed reaches a certain set value, the centrifugal force overcomes the elastic force of the damping spring 1014, so that the centrifugal block 1013 moves outward and contacts the transmission component and generates friction. At this time, the clutch enters the engagement state, the power is transmitted to the transmission component through the centrifugal block, and the power output is realized. The main body 101 is the core support structure of the clutch, and the assembly cavity 1012 inside the main body 101 is used for installing the centrifugal block 1013 and the damping spring 1014. The protective silica gel 102 plays a damping and protection role. The assembly partition plate 103 and the assembly hole 104 are used for fixing and limiting other components. The edge clamp plate 201 is connected with the convenient assembly tool 3 through the fixing screw hole 202 and the limiting assembly hole 203, so as to ensure the stability and reliability of the clutch during high-speed rotation. The limiting block 1013 is a key component of the clutch, which contacts the transmission component when moving outward to realize power transmission. The damping spring 1014 is used for controlling the movement of the centrifugal block, ensuring that it remains in the separated state at low speed and can be stably engaged at high speed. During the starting stage, when the clutch starts to rotate, the speed is low, the centrifugal force is not enough to overcome the elastic force of the damping spring 1014, the centrifugal block 1013 remains in the state of inward retraction, the clutch is in the separated state, and the power is not transmitted. Then, with the increase of the speed, the centrifugal force gradually increases.When the rotating speed reaches the set value, the centrifugal force overcomes the elastic force of the damping spring 1014, the centrifugal block 1013 moves outward, contacts with the transmission component and generates friction force, the clutch enters the engagement state, and the power starts to be transmitted.
