Use cylindrical protrusions for conduction. After the output end has been tightened, when you continue to exert force on the input end, the belt 9 will slide with the input pulley 4 or output pulley 5 and produce obvious vibration. Feeling the shock, thereby stopping the application of force, can effectively prevent the thread from slipping or breaking due to excessive force, and can also effectively reduce the wear of the device. The torque required to conduct the slippage can be changed by adjusting the length of the belt 9, thereby limiting the maximum torque generated by the device.

As shown in FIG. 3 , preferably, a pedal 13 is provided on the same side of the box body 1 as the output rod 3 away from the top cover 12 . When using the tool, the user depresses the pedal 13 with his or her feet to prevent the device from vacating when the rocking bar 6 is pulled upwards.

As shown in FIG. 3 , preferably, the box body 1 is telescopically provided with a stabilizer 15 at the end away from the tool box 11 , and the stabilizer 15 is located on both sides adjacent to the output rod 3 . When in use, pulling out the stabilizer 15 can prevent the device from swaying or even toppling when in use, and when not in use, the stabilizer 15 can be pushed back into the box for easy storage.

As shown in Fig. 3-4, preferably, the two sides of the box body 1 are provided with the stabilizer 15 to be provided with chute 16, and the chute 16 is movably provided with a support frame 17, and the end of the support frame 17 away from the chute 16 is rotatably connected to a stable On the frame 15, fixed teeth 18 are arranged in the chute 16. The support frame 17 is set to prevent the deformation of the stabilizer 15 due to excessive strength. The support frame 17 can be fully accommodated in the chute 16 when not in use, and the stabilizer 15 is pulled away. Since one end of the support frame 17 is connected to the stabilizer 15, the support frame 17 will tilt, and the end away from the stabilizer 15 will descend along the chute 16. At this time, the end face will form a ratchet-like structure with the fixed teeth 18 to prevent the support frame 17 from being displaced when it is subjected to an upward force, thereby playing a supporting role. When stabilizing the frame 15, push the support frame 17 toward the opening direction of the chute 16 to complete the storage.

As shown in Figure 5, preferably, a telescopic sleeve 21 is provided at the joint between the rocker 6 and the input rod 2, and the telescopic sleeve 21 enables the rocker 6 to expand and contract along the axial direction of the input rod 2, and the box body 1 is arranged on the side close to the rocker 6 There are 19 storage slots. When not in use, the rocking rod 6 can be stored in the storage groove 19 to avoid free rotation of the rocking rod 6 when moving and transporting, and the cardan shaft 7 can also be fixed while the rocking rod 6 is fixed.

As shown in Figure 6, preferably, the cardan shaft 7 includes a main shaft body 710 and a movable sleeve 720 covered outside the main shaft body 710; the main shaft body 710 includes several joint elements, and each joint element includes a transmission shaft fork 711, One end of the transmission shaft fork 711 is rotatably connected to two opposite shaft heads of the cross shaft 712, and the two adjacent shaft heads of the cross shaft 712 and the transmission shaft fork 711 are rotatably connected to the driven shaft fork 713. The end of the moving shaft fork 713 away from the cross shaft 712 is connected to the transmission shaft fork 711 on the adjacent joint element through the telescoping ring 714 . The transmission shaft fork 711 and the driven shaft fork 713 of each joint element are both rotatably connected to the cross shaft 712. When there is an angular displacement between the two shafts, the shaft fork rotates around their respective fixed axes, thereby causing the cross shaft to move in space. As a whole, the transmission shaft fork 711 and the driven shaft fork 713 are rotated in the same direction. Working under the condition that there is an included angle between the input and output shafts, the angular velocity of the two shafts is not equal, which will cause vibration and displacement of the output shaft and the transmission parts connected to it. Therefore, there is a joint between the joint elements. The telescoping ring 714 allows small displacements between adjacent joint elements to reduce wear.

As shown in FIG. 3 , preferably, a fixing knob 81 is pierced on the sleeve 8 . There is a strong magnet in the sleeve 8 itself, and in addition, screwdriver bits or nut barrels of different specifications can be squeezed on the inner wall of the sleeve 8 by rotating the fixing knob 81 for further fixing.
