Examples

The present embodiment provides a disassembly tool, as shown in fig. 1 to 3, comprising a sleeve 100, a coupling wrench 200 and a ferrule 300; the sleeve 100 is provided with a shaft hole 110 along the axial direction thereof, a first end (the left end of the sleeve 100 shown in fig. 1) of the side wall of the sleeve 100 is provided with a side opening 120 along the axial direction thereof, the shaft hole 110 is communicated with the side opening 120, and the end part of the shaft hole 110 communicated with the side opening 120 is used for being inserted into the torque wrench 400; the connection wrench 200 is inserted into the shaft hole 110 through the side opening 120 and is inserted into a portion of the shaft hole 110, and one end of the connection wrench 200 can protrude out of the second end of the socket 100 (shown as the right end of the socket 100 in fig. 1); a ferrule 300 is coupled to the first end of the sleeve 100 for axially securing the connection wrench 200.

In the disassembling tool provided by this embodiment, the sleeve 100 is provided with the shaft hole 110 and the side hole 120 which are communicated with each other, and because the side hole 120 is axially arranged along the first end of the side wall of the sleeve 100, the connection wrench 200 is inserted into the shaft hole through the side hole 120 and is inserted into the shaft hole 110, and the connection wrench 200 protruding out of the second end of the sleeve 100 can be used for disassembling components such as bolts; further, a ferrule 300 is connected to the first end of the sleeve 100 for axially securing the connection wrench 200 so that the sleeve 100, the connection wrench 200, and the ferrule 300 can be connected together.

As can be seen from the foregoing, when the connection wrench 200 is in operation, wherein the connection wrench 200 is inserted into the portion of the shaft hole 110, and the ferrule 300 can axially fix the connection wrench 200, the above arrangement enables no relative rotation between the sleeve 100 and the connection wrench 200, so that the torque generated by the force applied to the connection wrench 200 can be reduced, and the bending of the connection wrench 200 during operation can be reduced.

In addition, the end of the shaft hole 110 corresponding to the first end of the sleeve 100 is used for being plugged with a torque wrench, and the disassembling tool can be used in cooperation with the torque wrench, so that an operator can disassemble parts such as bolts conveniently. In addition, the disassembling tool comprises the sleeve 100, the connection wrench 200 and the ferrule 300, and has the advantages of fewer parts, relatively simple structure, relatively small volume and weight and convenient carrying for operators.

In this embodiment, the ferrule 300 is removably coupled to the first end of the sleeve 100.

Specifically, the ferrule 300 is inserted into the first end of the sleeve 100.

In this embodiment, the cross-sectional shape of the shaft hole 110 along the axial direction thereof may be the same, for example, the cross-sectional shape of the shaft hole 110 is a hexagon (not shown in the drawings), and in this structure, the cross-sectional shape of the portion of the torque wrench for insertion is also a hexagon. The structure is suitable for disassembling the inner hexagon bolt or the inner hexagon screw.

When the cross section of the shaft hole 110 is in a shape of a straight line, the cross section of the part of the torque wrench for plugging is also in a shape of a straight line, and the structure is suitable for disassembling an internal straight bolt or an internal straight screw.

When the cross section of the shaft hole 110 is in a quincunx shape, the cross section of the part of the torque wrench for plugging is also in a quincunx shape, and the structure is suitable for disassembling an internal quincunx bolt or an internal quincunx screw.

In addition to the above arrangement, in the present embodiment, the shaft hole 110 includes a first hole portion and a second hole portion; the first hole portion is used for inserting the connection wrench 200, and the shape of the first hole portion is matched with the shape of the connection wrench 200; the second hole portion is located at the first end of the socket 100 and is used for plugging with a torque wrench.

In some embodiments, the first bore portion has a hexagonal cross-sectional shape (not shown in the drawings) for mating with an allen wrench (the connection wrench 200 is an allen wrench); the cross-sectional shape of the second hole portion may also be polygonal, such as hexagonal. The structure is suitable for disassembling the inner hexagon bolt or the inner hexagon screw.

In this embodiment, the cross-sectional shape of the second hole portion is a quadrangle.

Illustratively, when the cross-sectional shape of the first hole portion of the shaft hole 110 is a line, the cross-sectional shape of the second hole portion is a polygon, such as a quadrangle; the structure is suitable for disassembling the inner straight bolt or the inner straight screw. When the cross-sectional shape of the shaft hole 110 is "quincunx", the cross-sectional shape of the second hole portion is polygonal, such as quadrilateral; the structure is suitable for disassembling the inner plum bolt or the inner plum screw.

Referring to fig. 2, the socket 100 has a round bar shape, and the length of the socket 100 is less than that of the connection wrench 200, so that the end of the connection wrench 200 away from the ferrule 300 after the connection wrench 200 is installed can protrude from the shaft hole 110 of the socket 100.

With reference to fig. 1 and 4, the ferrule 300 has a circular bore, a portion of the bore wall of the circular bore extending radially inward thereof forming a boss 310; the ferrule 300 is sleeved on the first end of the sleeve 100 through a circular hole, and the boss 310 is inserted into the side hole 120.

Further, the size of the ferrule 300 along the axial direction thereof is smaller than the size of the side opening 120 along the axial direction thereof, so as to ensure that the ferrule 300 can be completely sleeved on the sleeve 100 after the connection wrench 200 is installed.

Optionally, the sum of the dimension of the ferrule 300 in its axial direction and the maximum diameter of the connection wrench 200 is equal to the dimension of the side aperture 120 in its axial direction.
