Referring to fig. 1 to 3, the embodiment of the present invention discloses a special wrench for a mandrel, including a handle 100 and a mandrel sleeve 200 located at the end of the handle 100, a first sleeving part 210 and a second sleeving part 220 communicated with the first sleeving part 210 are provided in the mandrel sleeve 200, the end of the mandrel enters into the second sleeving part 220 after passing through the first sleeving part 210, the first sleeving part 210 is in a cylindrical shape, and the circumferential inner wall of the second sleeving part 220 has a first limiting surface 221 for limiting the rotation of the mandrel relative to the mandrel sleeve 200.

The special spanner for the core rod is sleeved on the core rod through a core rod sleeve 200 to operate the core rod, a first limiting surface 221 in a second sleeve part 201 can rotate the core rod to be limited, a worker holds a handle 100 to rotate the core rod sleeve 200, the core rod can be driven to rotate or move the core rod, the core rod cannot slip in the core rod transfer process, the core rod sleeve 200 can be remotely controlled through the handle 100, the worker can be far away from the core rod, the high-temperature influence on the core rod is avoided, the scalding accident is reduced, the transfer of the core rod is controlled through the handle 100, a certain distance exists between the hand of the operator and the core rod sleeve 200, and according to the lever principle, the operator can easily save labor when operating the core rod.

In the above, the first limiting surface 221 is a straight surface, and the inner wall of the second sleeving and connecting part 220 has four surfaces, which are two symmetrical straight surfaces and two symmetrical arc surfaces, respectively, and the two straight surfaces contact with the end of the mandrel to limit the rotation of the mandrel.

For convenience of use, the end of the mandrel is prevented from not being inserted into the second sleeving part 220, a chamfer structure 211 is arranged at the joint of the first sleeving part 210 and the second sleeving part 220, and under the action of the chamfer structure 211, the end of the mandrel can be guided to be inserted into the second sleeving part 220, so that the end of the mandrel is prevented from being blocked during insertion.

When facing the plug of different specifications, use the special spanner of different specifications, but so use convenience inadequately to can increase the manufacturing cost of special spanner, refer to fig. 1, fig. 2 and fig. 4, in the utility model discloses a further embodiment, handle 100 tip is equipped with adapter sleeve 110, plug sleeve 200 detachable installs on adapter sleeve 110, so, plug sleeve 200 can be pulled down from handle 100 and replace, when handling the plug of different sizes, can use the plug sleeve 200 of different specifications, high durability and convenient use, the production quantity of handle 100 is less than the production quantity of plug sleeve 200 when manufacturing, can save special spanner's manufacturing cost.

Specifically, the mandrel sleeve 200 includes a sleeve portion 201 and a mounting portion 202 connected to each other, the first sleeving portion 210 and the second sleeving portion 220 are located in the sleeve portion 201, the mandrel sleeve 200 is mounted on the connecting sleeve 110 through the mounting portion 202, when the mandrel is moved by using the special wrench, the end portion of the mandrel is inserted into the sleeve portion 201, and the mounting portion 202 is only responsible for the connecting sleeve 110 and connected to the connecting sleeve 110, so that the sizes of the mounting portions 202 of the mandrel sleeves 200 of different specifications can be consistent, the size of the connecting sleeve 110 can be kept constant, and the production and manufacturing of the special wrench are facilitated.

Referring to fig. 2 and 4, based on the above embodiment, in another embodiment of the present invention, the connection sleeve 110 is provided with a mounting hole 120 which runs through from front to back and has the same shape as the mounting portion 202, the mounting portion 202 is in insertion fit with the mounting hole 120, the inner wall of the mounting hole 120 is provided with a second limiting surface 121 which can limit the rotation of the mounting portion 202 relative to the connection sleeve 110, the mandrel sleeve 200 is mounted on the handle 100 in an insertion fit manner, the installation is convenient and the use is easy, and under the action of the second limiting surface 121, the mandrel sleeve 200 cannot rotate relative to the connection sleeve 110, so that the handle 100 can be used to remotely control the movement of the mandrel.

The second limiting surface 121 is a straight surface, and the mounting portion 202 also has a straight surface capable of being matched with the second limiting surface 121, so as to limit the rotation of the mounting portion 202 in the mounting hole 120, the cross-sectional shape of the mounting portion 202 may be various shapes such as a quadrangle, a triangle, a trapezoid, etc., or may be formed by a plurality of arc edges, and if so, the second limiting surface 121 is an arc surface.

In order to prevent the mounting portion 202 from falling off from the connecting sleeve 110 during operation, the length of the mounting portion 202 is set to be greater than the depth of the mounting hole 120, so that the mounting portion 202 can penetrate through the mounting hole 120 for a certain distance after the mandrel sleeve 200 is mounted on the handle 100, the mandrel sleeve 200 needs to move for a certain distance along the axial direction of the mounting hole 120 to be dismounted from the handle 100, and when the handle 100 is used specially, the mandrel sleeve 200 is not easy to separate from the handle 100, and therefore the use of a worker is not affected.

Referring to fig. 4 and 5, further, in another embodiment of the present invention, the handle 100 includes a grip portion 130 and an extension portion 140 connected to each other, the mandrel sleeve 200 is mounted on the extension portion 140, the upper end of the extension portion 140 is provided with a threaded shaft 141, and the extension portion 140 is threadedly engaged with the grip portion 130 through the threaded shaft 141.

When the special spanner is used, a worker holds the holding part 130, the extension part 140 is used for connecting the mandrel sleeve 200, the palm of the user can be far away from the mandrel, and the safety in the operation process is improved; the extension 140 and the grip 130 are detachably connected, and when the mandrel is moved using the handle 100 after the extension 140 and the grip 130 are screwed, the mandrel is moved or rotated in the radial direction of the mandrel, and the handle 100 does not rotate in the longitudinal direction thereof during the process, so that the extension 140 and the grip 130 are not separated from each other during the operation, and the extension 140 having different lengths is selected as needed, which is highly applicable.

In this way, when the operation is performed, the operation with a low error rate and high safety is realized by selecting the appropriate operating distance and then selecting the mandrel sleeve 200 fitted to the mandrel.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification which does not depart from the functional and structural principles of the present invention is intended to be included within the scope of the claims.
