In this embodiment, as shown in fig. 1,2, and 5-7, the second protection plate 23 is stabilized on the protection shell 21 by the spring buckles 211 disposed up and down on two sides, when the force for pulling the connection assembly 3 is large, the second protection plate 23 presses the spring buckles 211 into the protection shell 21, so that the second protection plate 23 can rotate to complete the separation between the connector 331 and the metal buckle 41, the second transmission line 321 is in a threaded shape, the connecting spring 322 is disposed in the middle of the threaded ring, the top of the second transmission line 321 is connected with the first transmission line 311, and the bottom of the second transmission line 321 is connected with the connector 331.
According to the technical scheme provided by the invention, the wearing component is arranged, when a user needs to perform man-machine interaction with the monitoring equipment and rotate the forearm to cause the buckle belt to incline at an angle, the adjusting part can firmly clamp the metal buckle on the electrode body, so that the electrode body can be stably adhered to the skin, the situation that the electrode body is separated from the skin when the forearm rotates or stretches is avoided, and the monitoring equipment can acquire surface electromyographic signals more stably.
Through setting up protection component, when the user is carrying out the unexpected circumstances such as forearm swing amplitude is great and the like and is being pulled first transmission line in carrying out man-machine interaction, can be automatic disconnect the connection between coupling assembling and the electrode body, realized the protection to electrode body and coupling assembling junction, avoided the damage of the junction between transmission line and the electrode body when pulling by force.
Through setting up the adjustment part of wearing the subassembly, when using, no matter what posture is put out to user's forearm, adjustment part always makes protection subassembly and electrode body keep in same position, makes stable the connection between coupling assembling and the electrode body, has realized in the in-process of using, no matter how complicated the action of man-machine interaction, this device always normal use.
