[0026] Specifically, in the above-mentioned specific embodiment, after the transverse fixed block 101 is fixed, the transverse linear bearing 103 can slide stably on the transverse moving guide rail 102, thereby driving the transverse sliding block 105 to slide stably horizontally, and connected with the longitudinal moving mechanism 2 through the rotating bearing 104, thereby ensuring the stability of the rotating support shaft 201 during rotation, and finally achieving the stable horizontal movement of the electric screwdriver body 304, and further improving the stability during movement through the auxiliary sliding block 4.
[0027] Reference Figure 3 A longitudinal moving mechanism 2 is fixedly arranged at the lower end of the rotating bearing 104, and the longitudinal moving mechanism 2 includes a rotating support shaft 201, a fixed rotating block 204 is fixedly arranged at the upper end of the rotating support shaft 201 bearing, a longitudinal linear bearing 205 is provided at the middle of the rotating support shaft 201 bearing, a balancer 202 is fixedly arranged on one side of the fixed rotating block 204, a mounting slot 206 is provided at the front end of the longitudinal linear bearing 205, a fixed adjustment plate 302 is fixedly arranged inside the mounting slot 206, a lifting hook 203 is fixedly connected to the lower end of the balancer 202, and the lifting hook 203 is fixedly connected to one side of the longitudinal linear bearing 205;
[0028] Specifically, in the above-mentioned specific embodiment, the swinging moving mechanism 3 can be fixed on the longitudinal moving mechanism 2, so that the swinging moving mechanism 3 can be driven to move longitudinally stably during the stable movement of the longitudinal moving mechanism 2, and the horizontal position of the fixed rotating block 204 is fixed, which can drive the balancer 202 to be fixed at a specified height, and the pulling force of the balancer 202 can lift the electric screwdriver body 304 inside the swinging moving mechanism 3 to prevent the electric screwdriver from falling when the person releases the electric screwdriver, and finally realize the stable longitudinal movement of the electric screwdriver body 304.
[0029] Reference Figure 4The front end of the fixed rotating block 204 is provided with a swinging moving mechanism 3, which includes a fixed adjusting plate 302 and an electric screwdriver body 304. A support frame 301 is fixedly provided on one side of the front end of the fixed adjusting plate 302. A longitudinal frame 303 is rotatably provided inside the support frame 301. A fixed clamp 305 is fixedly provided on one side of the longitudinal frame 303. The electric screwdriver body 304 is clamped and provided inside the fixed clamp 305.
[0030] Specifically, in the above-mentioned specific embodiment, the electric screwdriver body 304 can be connected to the swinging movement mechanism 3, and can be swung and moved by swinging the longitudinal frame 303, thereby increasing the movable direction of the electric screwdriver body 304 when the staff holds it.
[0031] Ultimately, the staff can hold the electric screwdriver body 304 to control the direction and position, specifically by limiting the displacement with the lateral moving mechanism 1, the longitudinal moving mechanism 2 and the swinging moving mechanism 3, and further improving the stability during movement through the auxiliary sliding block 4, so that the staff can operate the electric screwdriver body 304 without being subjected to the vibration of the electric screwdriver caused by the locking torque, and at the same time, the staff will not be unable to hold the electric screwdriver for a long time due to the vibration of the electric screwdriver.
[0032] Working principle: When using the power-assisting arm mechanism, first install the electric screwdriver body 304 into the inside of the fixed clamp 305, and then the staff can hold the electric screwdriver body 304 to control the direction and position. The electric screwdriver body 304 is limited in displacement by the lateral moving mechanism 1, the longitudinal moving mechanism 2 and the swinging moving mechanism 3. When the electric screwdriver body 304 moves laterally, it slides on the lateral moving guide rail 102 through the lateral linear bearing 103, and is limited by the auxiliary sliding block 4 and the lateral linear guide rail 5 to ensure that the lateral movement is a linear displacement. When the electric screwdriver body 304 moves longitudinally, the longitudinal linear bearing 205 ensures that the longitudinal movement is a linear displacement. At the same time, the pulling force of the balancer 202 can lift the electric screwdriver body 304 to prevent it from falling when the staff releases the electric screwdriver body 304. When the electric screwdriver body 304 swings and moves, the rotating bearing 104 ensures the rotation stability of the rotating support shaft 201, thereby achieving stable swing displacement.
