DETAILED DESCRIPTION

[0024] The utility model provides Figure 1-5 A protective one-way jumping head torque device is shown, comprising:

[0025] The main body 1 has a connecting arm 11 fixedly mounted on the outer surface of one end of the main body 1, and is connected to the device connecting shaft through the connecting arm 11;

[0026] An input shaft 2, which is arranged inside the main body 1, with a connecting pipe 21 fixedly mounted on one end of the input shaft 2, and a block assembly provided on the outer surface of the input shaft 2, through which the input shaft 2 performs unidirectional transmission on the main body 1;

[0027] The collar 3 is sleeved on one end of the outer surface of the input shaft 2, and the collar 3 is rotatably connected to the input shaft 2. A limit assembly is provided on the outer surface of the collar 3, and the collar 3 is limited and locked by the limit assembly.

[0028] In a preferred embodiment, Figure 2 As shown, a rotating shaft 12 is provided inside the main body 1, and limit pins 14 are inserted into the two sides of the interior of the main body 1, and one end of the limit pin 14 is inserted into the groove of the rotating shaft 12. The rotating shaft 12 is rotatably connected to the main body 1, and the other end of the input shaft 2 is fixedly connected to the rotating shaft 12. During the rotation of the rotating shaft 12, the rotating shaft 12 can be limited by the limit pin 14.

[0029] In a preferred embodiment, Figure 2-3As shown, the block assembly includes a mounting groove 24 provided inside the input shaft 2 and a second block 23 provided around the mounting groove 24. The inner walls of the main body 1 and the collar 3 are provided with a slot 13 around them. One end of the second block 23 is inserted into the slot 13 to complete the one-way transmission connection between the input shaft 2 and the main body 1. When the driving device drives the input shaft 2 to rotate forward, the first block 22 will drive the main body 1 to rotate, thereby further driving the connecting shaft of the device to rotate. When the input shaft 2 rotates reversely, the second block 23 will be pressed inward.

[0030] like Figure 4 As shown, a first clamping block 22 is arranged around the inside of the input shaft 2 on one side of the second clamping block 23, a sliding column 27 is fixedly installed at one end of the first clamping block 22, and the first clamping block 22 is fixedly connected to the second clamping block 23 through the sliding column 27, a sliding groove 25 is opened on the inner wall of the mounting groove 24, and the sliding column 27 is slidingly connected to the input shaft 2 through the sliding groove 25, and a first return spring 26 is arranged at the bottom end of the first clamping block 22 inside the input shaft 2, and the first clamping block 22 will press the second clamping block 23 on one side into the input shaft 2 along the sliding groove 25 through the sliding column 27, thereby releasing the transmission connection between the input shaft 2 and the main body 1, avoiding damage to the equipment caused by incorrect operation during maintenance, and increasing the safety of use.

[0031] Furthermore, the limit assembly includes a pin 31 inserted into the top of the collar 3, a limit block 33 is fixedly installed at the bottom end of the pin 31, a limit block 33 matching the limit groove 34 is provided on the outer surface of the input shaft 2, and a second return spring 32 is sleeved on the outer surface of the pin 31 located above the limit block 33. The pin 31 is pulled upward to drive the limit block 33 at the bottom to disengage from the limit groove 34, thereby releasing the limit on the collar 3, and then the collar 3 is rotated forward. During the movement of the limit block, the second return spring 32 will be squeezed.

[0032] Working principle of this utility model:

[0033] Refer to the instruction manual Figure 1-5When in use, the connecting arm 11 is connected to the connecting shaft of the device, and the connecting pipe 21 is connected to the driving device of the device. When the driving device drives the input shaft 2 to rotate forward, the first clamping block 22 will drive the main body 1 to rotate, thereby further driving the connecting shaft of the device to rotate. When the input shaft 2 rotates reversely, the second clamping block 23 will be pressed inwardly, squeezing the first return spring 26 inside, and the main body 1 cannot be driven to continue rotating, thereby achieving the effect of one-way conveying rotation. When the device fails, the latch 31 can be pulled upward first to drive the limit block 33 at the bottom to disengage from the limit groove 34, release the limit on the collar 3, and then rotate the collar 3 forward to press the first clamping block 22 on the inside inwardly. The first clamping block 22 will press the second clamping block 23 on one side into the input shaft 2 along the slide groove 25 through the slide column 27, thereby releasing the transmission connection between the input shaft 2 and the main body 1, avoiding damage to the equipment caused by incorrect operation during maintenance, and increasing the safety of use.
