[0031] 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.

[0032] Reference Figure 1-3The utility model provides an embodiment: an intelligent mechanical arm that is easy to install, including a mechanical arm body 1, a base 2 is arranged at the bottom of the mechanical arm body 1, a transmission gear ring 3 is sleeved on the bottom of the surface of the mechanical arm body 1, a placement plate 4 is fixedly connected to the bottom of the mechanical arm body 1, and the placement plate 4 can place the mechanical arm body 1 inside the placement opening 7 to prevent the mechanical arm body 1 from shaking, and a center rod 5 is fixedly connected to the top of the placement plate 4, and a semi-toothed card plate 6 is sleeved on the surface of the center rod 5. The semi-toothed card plate 6 can rotate to the inside of the stable opening 8 after the surface of the center rod 5 is rotated, and is limited by the base 2, so that the mechanical arm body 1 is quickly connected to the base 2, and the semi-toothed card plate 6 is meshed with the surface of the transmission gear ring 3, and a placement opening 7 is opened on the inner wall of the base 2, and a stable opening 8 is opened on the inner wall of the placement opening 7. The placement opening 7 can limit the placement plate 4 at the bottom of the mechanical arm body 1, and stabilize The mouth 8 can clamp the semi-toothed clamping plate 6 inside the base 2, so that the base 2 and the mechanical arm body 1 are stably connected. A clamping assembly is provided on the top of the placement plate 4, and the clamping assembly includes a clamping block 9, which is located on the outer side of the transmission gear ring 3, and the outer side of the clamping block 9 is fixedly connected to the limiting rod 10. The top of the placement plate 4 is fixedly connected with a stabilizing plate 11, and the outer side of the limiting rod 10 penetrates to the outer side of the stabilizing plate 11. The surface of the limiting rod 10 is sleeved with a tightening spring piece 12, and the front side of the tightening spring piece 12 is fixedly connected to the back side of the clamping block 9, and the back side of the tightening spring piece 12 is fixedly connected to the front side of the stabilizing plate 11. Driven by the tightening spring piece 12, the clamping block 9 makes the limiting rod 10 pulled by the clamping block 9 to slide inside the stabilizing plate 11, so that the clamping block 9 is clamped on the surface of the transmission gear ring 3 to prevent the transmission gear ring 3 from rotating, thereby achieving the effect of facilitating the connection between the base 2 and the mechanical arm body 1.

[0033] Reference Figure 2-4 The inner wall of the transmission gear ring 3 is fixedly connected with a pulling spring piece 16, the inner side of the pulling spring piece 16 is fixedly connected to the surface of the mechanical arm body 1, and the inner sliding connection of the pulling spring piece 16 is a fixing rod 17, and the fixing rod 17 is fixedly connected to the inner wall of the transmission gear ring 3 at one end close to the transmission gear ring 3. The pulling spring piece 16 continues to pull the transmission gear ring 3 after the transmission gear ring 3 rotates under the limit of the fixing rod 17, so that the transmission gear ring 3 is continuously pulled, and when the base 2 and the mechanical arm body 1 need to be disassembled after the clamping block 9 is detached from the transmission gear ring 3, the transmission gear ring 3 is quickly reset after being pulled by the pulling spring piece 16, and then rotated to rotate the half-tooth clamping plate 6, so that the half-tooth clamping plate 6 is moved out from the inside of the stable opening 8 after rotating on the surface of the center rod 5, thereby achieving the effect of quickly disassembling the base 2 and the mechanical arm body 1.

[0034] Reference Figure 2-4The top of the transmission gear ring 3 is slidably connected with a stabilizing rod 14, and the bottom of the stabilizing rod 14 is fixedly connected to the top of the placing plate 4. One end of the stabilizing rod 14 and the other end of the placing plate 4 slide inside the transmission gear ring 3 to prevent the transmission gear ring 3 from shaking up and down, so that the transmission gear ring 3 can be used in a stable rotation. The top of the stabilizing plate 11 is slidably connected with a pulling plate 13, and the bottom of the pulling plate 13 is fixedly connected to the top of the clamping block 9. The pulling plate 13 can facilitate the user to pull the clamping block 9, so that the clamping block 9 is quickly pulled and then separated from the surface of the transmission gear ring 3, thereby facilitating the user to release the limit of the clamping assembly and the transmission gear ring 3. The inner wall of the stable port 8 is fixedly connected with a friction pad 15, and the shape of the friction pad 15 is arc-shaped. On the one hand, the friction pad 15 increases the friction between the semi-toothed clamping plate 6 and the stable port 8, and on the other hand, it is not easy to produce collision and noise after the semi-toothed clamping plate 6 is connected to the stable port 8.

[0035] Working principle: When in use, the user first places the placement plate 4 at the bottom of the base 2 into the placement opening 7 at the top of the robotic arm body 1, and then rotates the transmission gear ring 3 so that the transmission gear ring 3 drives the half-toothed card plate 6 to rotate on the surface of the center rod 5 through the meshing transmission with the half-toothed card plate 6, so that the half-toothed card plate 6 is rotated and stuck in the inside of the stable opening 8 and contacts with the friction pad 15, thereby achieving the effect of facilitating the connection between the base 2 and the robotic arm body 1, and the clamping block 9 drives the limit rod 10 to slide inside the stable plate 11 under the pressure of the clamping spring piece 12, so that the clamping block 9 slides on the top of the placement plate 4 and is stuck on the surface of the transmission gear ring 3 to prevent the transmission gear ring 3 and the half-toothed card plate 6 from rotating, thereby stably connecting the robotic arm body 1 and the base 2.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
