A handle 217 is movably installed through the inside of the connecting groove 221 and away from the support plate 203. One end of the handle 217 is snap-fitted inside the rotating shaft 202.

[0025] As Figures 4 to 7As shown, in another embodiment of the present utility model, an auxiliary groove 205 is provided inside the placement groove 201 and on the side far from the sliding groove 206. One end of the rotating shaft 202 away from the handle 217 is installed with a rotating block 204, and the rotating block 204 is movably installed inside the auxiliary groove 205. One end of the handle 217 located inside the connection groove 221 is installed with a conical block 208, and the conical block 208 is movably installed inside the connection groove 221. A spring 218 is sleeved and installed on the outer side of the rod body of the handle 217 between the conical block 208 and the connection groove 221. One end of the conical block 208 away from the handle 217 is installed with an extension rod 209, and the extension rod 209 is movably installed inside the connection groove 221 and the rotating shaft 202. On the side of the slider 207 away from the rotating shaft 202, a number of limiting holes 220 are arranged in a circumferential array with the handle 217 as the center. One end of the handle 217 away from the conical block 208 and close to the slider 207 is installed with a limiting rod 219, and the limiting rod 219 is snap-fitted inside the limiting hole 220. Inside the rotating shaft 202 near one end of the slider 207, a groove 210 is provided. The extension rod 209 is snap-fitted inside the groove 210. One end of the extension rod 209 located inside the groove 210 is installed with a limiting plate 211, and the limiting plate 211 is movably installed inside the groove 210. Guide rods 212 are respectively installed at the upper and lower ends inside the groove 210, and the rod bodies of the guide rods 212 respectively pass through and are movably installed inside the limiting plate 211. At the upper end inside the slider 207, a limiting groove 215 is provided. A positioning rod 213 is movably installed through the inside of the limiting groove 215. The lower end of the positioning rod 213 is movably installed through the inside of the connection groove 221, and the lower end of the positioning rod 213 is in contact with the rod bodies of the conical block 208 and the extension rod 209. At the upper end of the rod body of the positioning rod 213 located inside the limiting groove 215, a pressing plate 216 is installed, and the pressing plate 216 is movably installed inside the limiting groove 215. A number of positioning holes 214 are provided at the upper end inside the sliding groove 206. The upper end of the positioning rod 213 is movably installed inside the sliding groove 206 and is snap-fitted inside the positioning holes 214.

[0026] When the user needs to adjust the angle of the chassis body 1, the user first pulls the handle 217 outwards, so that the handle 217 drives the conical block 208 and the extension rod 209 to move towards one side, causing the handle 217 to drive the limiting rod 219 to separate from the limiting hole 220. Then the handle 217 drives the conical block 208 to squeeze the spring 218. Then, as the conical block 208 moves, the pressing plate 216 will drive the positioning rod 213 to slide down along the surface of the conical block 208, so that the positioning rod 213 disengages from the inside of the positioning hole 214. Then the user can control the handle 217 to rotate, and then the handle 217 can drive the extension rod 209 to drive the rotating shaft 202 and the support plate 203 to adjust the angle through the engagement between the limiting plate 211 and the guiding rod 212. At the same time, the user can also drive the slider 207 and the rotating shaft 202 to move along the sliding groove 206 and the placement groove 201 through the handle 217 to adjust the position of the support plate 203. Then, after the position and angle of the support plate 203 are adjusted, the user can release the handle 217, and the spring 218 will push the conical block 208 to reset. Then, as the conical block 208 moves, the handle 217 will drive the limiting rod 219 to insert into the corresponding limiting hole 220 to realize the positioning of the handle 217. Then the conical block 208 will push the positioning rod 213 through the angle on its surface, so that the positioning rod 213 inserts into the corresponding positioning hole 214 to realize the positioning of the slider 207 and the support plate 203, and realize the positioning work of the angle and position of the support plate 203, which is more simple and convenient;

[0027] The limiting plate 211 and the guiding rod 212 are used to assist the extension rod 209 in moving, and at the same time, it is also convenient for the extension rod 209 to stably drive the rotating shaft 202 and the support plate 203 to adjust the angle, improving the overall stability;

[0028] The rotating block 204 and the auxiliary groove 205 are used to limit the position of the rotating shaft 202 to prevent the rotating shaft 202 from tilting, and at the same time, they are also used to assist the rotating shaft 202 in rotating and position adjustment, improving the stability of the rotating shaft 202 during rotation and movement.

[0029] The working principle of this kind of keyboard chassis support and elevation structure:

[0030] When in use, first, when the user needs to adjust the angle of the chassis body 1, the user first pulls the handle 217 outwards, causing the handle 217 to drive the conical block 208 and the extension rod 209 to move towards one side, so that the handle 217 drives the limit rod 219 to separate from the limit hole 220. Then, the handle 217 drives the conical block 208 to compress the spring 218. Then, as the conical block 208 moves, the pressing plate 216 drives the positioning rod 213 to slide down along the surface of the conical block 208, causing the positioning rod 213 to disengage from the inside of the positioning hole 214. Then, the user can control the handle 217 to rotate, and then the handle 217 can drive the extension rod 209 to drive the rotating shaft 202 and the support plate 203 to adjust the angle through the engagement between the limit plate 211 and the guide rod 212. At the same time, the user can also drive the slider 207 and the rotating shaft 202 to move along the sliding groove 206 and the placement groove 201 by the handle 217 to adjust the position of the support plate 203. Then, after the position and angle of the support plate 203 are adjusted, the user can release the handle 217, allowing the spring 218 to push the conical block 208 to reset. Then, as the conical block 208 moves, the handle 217 drives the limit rod 219 to insert into the corresponding limit hole 220 to achieve the positioning of the handle 217. Then, the conical block 208 pushes the positioning rod 213 through the angle on its surface, causing the positioning rod 213 to insert into the corresponding positioning hole 214 to achieve the positioning of the slider 207 and the support plate 203, and realize the positioning work of the angle and position of the support plate 203.

[0031] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is impossible to enumerate all the implementation manners here. Any obvious changes or variations derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
