In, due to the internal diameter of pullover be it is uncontrollable, this just needs to carry the pullover of plurality of specifications at work, require every time from
It is looked in tool box, to the new hand that bolt is not known, often will appear and tear bolt needs open and look for repeatedly, can just find just
True pullover, it is greatly inconvenient that this comes to work belt；To solve the above problems, developing a kind of easy to use, wide adaptation range
Combined wrench pullover is necessary.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of easy to use, adaptation range
Wide Combined wrench pullover.
Purpose of the utility model is realized as follows: a kind of Combined wrench pullover, including pullover, the pullover include
Connector and change pullover, the connector are located at the top of pullover, and the end face of the connector is provided with rectangular connecting hole, institute
The locking hole that is provided centrally with of a side of connecting hole is stated, the lower part of the pullover is provided with change pullover, the change pullover
End face is provided with fixed hexagon ring, and round slide opening, the circle slide opening are provided on the inside of each angle of the fixed hexagon ring
It is inside provided with rocker piece, the rocker piece includes circular pin and class corner block, and the circular pin is located in round slide opening, the class
Two sides of corner block are in contact with two sides of fixed hexagon ring, pass through between the class corner block and fixed hexagon ring
Compressed spring is attached, the compressed spring be fixed on by way of soldering or riveting class corner block and fixed hexagon ring it
Between.
Further, the inscribed circle diameter of the fixed hexagon ring is 17.2mm.
Further, the inscribed circle diameter of the rocker piece is 14.2mm.
Further, the material of the rocker piece uses 40Cr, and the hardness after high-frequency quenching is 55-60HRC.
Further, the height of the class corner block is 10mm.
Further, the material of the compressed spring uses 60Si2Mn.
By adopting the above-described technical solution, the beneficial effects of the utility model are:
(1) reduced when in use by the rocker piece of setting so that the utility model is suitable for the bolt of plurality of specifications
The number of pullover replacement, improves the efficiency of work；
(2) by the compressed spring of setting, so that rocker piece when encountering compared with king-bolt, can be compressed into round slide opening
It is interior, to not influence the normal use of pullover, after the completion of use, by compressed spring, rocker piece is enable to reset, thus not
Subsequent normal use is influenced, meanwhile, by the way that being slightly larger than for the inscribed circle setting of the inscribed circle and rocker piece of hexagon ring will be fixed
Normal bolt head specification, so that bolt head more smoothly can be protruded into or be extracted.

Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solution of the utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of Combined wrench pullover, including pullover 1, the pullover 1 include connection
First 11 are located at the top of pullover 1 with change pullover 12, the connector 11, and the end face of the connector 11 is provided with rectangular connection
Hole 1101, a side of the connecting hole 1101 are provided centrally with locking hole 1102 so that pullover 1 can with ratchet spanner or
Torque spanner is used in combination, and the lower part of the pullover 1, which is provided with, becomes pullover 12, and the end face for becoming pullover 12 is provided with fixation
Hexagon ring 1201 is provided with round slide opening 1202, the circle slide opening on the inside of each angle of the fixed hexagon ring 1201
Rocker piece 2 is provided in 1202, the rocker piece 2 includes circular pin 21 and class corner block 22, and the circular pin 21 is located at circle
In slide opening 1202, the deep equality of the length of the circular pin 21 and round slide opening 1202, two sides of the class corner block 22
Side is in contact with two sides of fixed hexagon ring 1201, passes through compression between the class corner block 22 and fixed hexagon ring 1201
Spring 3 is attached, and the compressed spring 3 is fixed on class corner block 22 and fixed hexagon ring by way of soldering or riveting
Between 1201, so that rocker piece 2 when encountering bolt, can be protruded into round slide opening 1202 by compressed spring 3.
The inscribed circle diameter of the fixed hexagon ring 1201 is 17.2mm.
The inscribed circle diameter of the rocker piece 2 is 14.2mm.
The material of the rocker piece 2 uses 40Cr, and the hardness after high-frequency quenching is 55-60HRC, guarantees rocker piece 2
Intensity and wearability improve the service life of rocker piece 2.
The height of the class corner block 22 is 10mm.
The material of the compressed spring 3 uses 60Si2Mn.
When the utility model is used, firstly, pullover 1 is mounted on torque spanner or ratchet wrench by locking hole 1102
On hand；Then, when encountering the bolt that bolt head is 17mm, since the inscribed circle diameter of fixed hexagon ring 1201 is 17.2mm,
Greater than the 17mm of bolt head, bolt head can be smoothly entered inside pullover 1, when bolt head enters 1 inside of pullover, bolt head
Top surface is contacted with rocker piece 2, so that rocker piece 2 is moved down along round slide opening 1202, so that pullover 1 is suitable for bolt
Head is the bolt of 17mm；Finally, rocker piece 2 resets under the action of compressed spring 3 after the completion of the use, when encountering bolt head
For 14mm bolt when, bolt is torn in the space that the inscribed circle diameter that can be directly combined by rocker piece 2 is 14.2mm open
