[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in the embodiment of the present application is to effectively solve the technical problem that when the current BT tool handle disassembly bracket is disassembled from the BT tool handle, it is necessary to frequently use a wrench to disengage and engage the wrench and the BT tool handle before the BT tool handle can be disassembled, which increases the fatigue of the staff when disassembling the BT tool handle. The overall idea is as follows: A universal placement and disassembly bracket for BT tool handles, comprising a bracket body 11, an oil fixing ring 12 is fixedly installed on the top of the bracket body 11, and a rotating mechanism is arranged inside the fixing ring 12, and the rotating mechanism includes a first piston rod 15, a first pawl 16, a second piston rod 17, a second pawl 18, a first ratchet 19 and a second ratchet 22, the first piston rod 15 is slidably installed inside the fixing ring 12, the first pawl 16 is fixedly installed on the end of the first piston rod 15 away from the fixing ring 12, the second piston rod 17 is slidably installed inside the fixing ring 12, and the second pawl 18 is fixedly installed At the end of the second piston rod 17 away from the fixing ring 12, the first ratchet 19 is meshed with the side wall of the first pawl 16, and the second ratchet 22 is meshed with the side wall of the second pawl 18. When the BT tool handle is inserted into the mounting ring 24, the wrench is rotated clockwise. When the wrench applies a clockwise rotational force to the BT tool handle, the second pawl 18 clamps the second ratchet 22 to ensure that the second ratchet 22 does not rotate. The bracket body 11 will hinder the clockwise rotation of the wrench. At this time, the wrench is rotated counterclockwise, and the BT tool handle drives the mounting ring 24 and the second fixing rod 23 to rotate counterclockwise, and the second fixing rod 23 drives the second ratchet 22 to rotate counterclockwise. When the second ratchet 22 rotates counterclockwise, the second pawl 18 is squeezed and expanded from the middle to the surrounding area by force, and the second piston rod 17 is compressed by force, so that the second ratchet 22 can easily rotate counterclockwise, reducing the number of times the wrench is engaged with the BT tool handle, thereby achieving the function of reducing the fatigue of the staff.

[0027] The first bolt 13 is installed with the internal thread of the fixing ring 12, the second bolt 14 is installed with the internal thread of the fixing ring 12, the first fixing rod 21 is fixedly installed on the top of the first ratchet 19, the second fixing rod 23 is fixedly installed on the top of the second ratchet 22, the first fixing rod 21 and the second fixing rod 23 are fixedly installed with the mounting ring 24 on the top, the mounting ring 24 is fixedly installed with a clamping block 25, the top of the mounting ring 24 is rotatably installed with a damping rod 26, the top of the damping rod 26 is fixedly installed with a clamping plate 27, the mounting ring 24 is provided with a slide groove 28, the slide groove 28 is slidably installed with a slide bar 29, and the slide bar A cylinder 31 is fixedly installed on the side wall 29, and a fixing block 32 is fixedly installed on the top of the cylinder 31. When the sizes of the BT tool handle and the mounting ring 24 are different, the cylinder 31 is inserted into the mounting ring 24, and the slide bar 29 slides along the inner wall of the slide groove 28. The cylinder 31 will be clamped on the top of the mounting ring 24, and the damping rod 26 is rotated counterclockwise. The damping rod 26 drives the clamping plate 27 to rotate counterclockwise into the square groove 33, and the cylinder 31 is fixed inside the mounting ring 24, so that the bracket can disassemble BT tool handles of other sizes, thereby enabling the bracket to disassemble BT tool handles of different sizes.

[0028] A square groove 33 is provided inside the fixing block 32 , and the clamping plate 27 is slidably installed inside the fixing block 32 , thereby increasing the stability of the bracket when in use.

[0029] In view of the problems existing in the prior art, the utility model provides a universal placement and disassembly bracket for BT tool handles. When the BT tool handle is inserted into the mounting ring 24, the wrench is rotated clockwise. When the wrench applies a clockwise rotational force to the BT tool handle, the second pawl 18 clamps the second ratchet 22 to ensure that the second ratchet 22 does not rotate. The bracket body 11 will hinder the clockwise rotation of the wrench. At this time, the wrench is rotated counterclockwise, and the BT tool handle drives the mounting ring 24 and the second fixing rod 23 to rotate counterclockwise. The second fixing rod 23 drives the second ratchet 22 to rotate counterclockwise. When the second ratchet 22 rotates counterclockwise, the second pawl 18 is forced to expand from the middle to the surroundings, and the second piston rod 17 is compressed by force, so that the second ratchet 22 can rotate counterclockwise easily, reducing the number of times the wrench is engaged with the BT tool handle, thereby achieving the function of reducing the fatigue of the staff. When the sizes of the BT tool handle and the mounting ring 24 are different, the cylinder 31 is inserted into the mounting ring 24, and the slide bar 29 slides along the inner wall of the slide groove 28. The cylinder 31 will be engaged on the top of the mounting ring 24, and the damping rod 26 is rotated counterclockwise. The damping rod 26 drives the clamping plate 27 to rotate counterclockwise into the square groove 33, and the cylinder 31 is fixed inside the mounting ring 24, so that the bracket can disassemble BT tool handles of other sizes, thereby enabling the bracket to disassemble BT tool handles of different sizes.

[0030] Working principle:

[0031] The first step is to place the BT tool handle inside the mounting ring 24, clamp the BT tool handle with the clamping block 25, use a wrench to clamp the BT tool handle, then rotate the second bolt 14 to leave the inside of the fixing ring 12, rotate the wrench clockwise, and apply rotational force to the BT tool handle with the handle. The second pawl 18 clamps the second ratchet 22, so that the second ratchet 22 cannot rotate clockwise, and then rotate the wrench counterclockwise. The wrench drives the BT tool handle to rotate counterclockwise, and the BT tool handle drives the clamping block 25 to rotate counterclockwise. The clamping block 25 drives the mounting ring 24 to rotate counterclockwise. The mounting ring 24 drives the second fixing rod 23 to rotate counterclockwise, and the second fixing rod 23 drives the second ratchet 22 to rotate counterclockwise. When the second ratchet 22 rotates counterclockwise, the second pawl 18 is forced to expand from the middle to the surrounding areas, and the second piston rod 17 is compressed, so that the second ratchet 22 can easily rotate counterclockwise, reducing the number of times the wrench and the BT tool handle are engaged, thereby achieving the function of reducing the fatigue of the staff.

[0032] In the second step, when the sizes of the BT shank and the mounting ring 24 are different, insert the cylinder 31 into the mounting ring 24, and the slide bar 29 slides along the inner wall of the slide groove 28. The cylinder 31 will be clamped on the top of the mounting ring 24, and the damping rod 26 will be rotated counterclockwise. The damping rod 26 drives the clamping plate 27 to rotate counterclockwise into the square groove 33, and the cylinder 31 is fixed inside the mounting ring 24, so that the bracket can disassemble BT shanks of other sizes, thereby enabling the bracket to disassemble BT shanks of different sizes.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description.
