In some working environments of electric and motor products, it is easy to become a conductor. It is fearful of leakage, which is harmful to the human body. Secondly, it has developed an insulated wrench. (4) The early insulating wrench, such as the Taiwan Announcement No. 4〇43〇6, invented the spear. The case only covered an insulating layer on the outer surface of the wrench. The structure is very simple, but it can eliminate the possibility of electrically conducting the human body, so it is safe and careless. And easy to use. * h• With the continuous advancement of technology, the traditional wrench derives the power of torque output. The torque value of such a torque wrench often needs to be adjusted. If the outer surface is still covered with an insulating layer, although the safety is not taken care of, the function of adjusting the torque is lost, so the structure of the insulating layer and the torque wrench are incompatible. In view of this, the inventors have in-depth discussion of the problems of the prior art, and actively pursued solutions to the experience of R&D and manufacturing of related industries for many years, and finally succeeded in developing an insulation structure suitable for a torque wrench to improve the use. The problem of the invention. 201213064 [Summary of the Invention] The main purpose of Xi'an is to use the multi-cut method to retain the part of the insulating layer and to cover the surface of the torque wrench together, so that the electrical barrier can not be transmitted to the human body. It has the function of adjusting the torque value. In order to achieve the above object, the improvement of the insulation structure of the torque wrench of the present invention is to assemble a torque mechanism in a torque wrench, and has an adjustment relationship with an adjustment button locked at the end of the torque wrench, and the torque wrench = table partial package An insulating layer is covered, and an insulating tube is placed on the uncoated portion. / The absolute, the tube ends of the tube and the insulation layer have a concave-convex fit relationship ^ The other - the official end is opposite to the adjustment button, so that the insulation tube and the insulation layer form - the body ' does not rotate around the torque wrench, which is good for holding Force. More importantly, the torque wrench removes the insulation tube, and the tool is adjusted to the value of the torque = and then the insulation tube is reinstalled. The output value of the residual torque can be saved early and the assembly is quick and convenient, and the insulation can be maintained. Security effect. As for the concavo-convex junction, the recessed portion is recessed at the end of the insulating layer facing the insulating tube, and the insulating tube protrudes from the tube wall by a convex portion, which can be in the recess of the relative position. Wherein, the insulating layer is formed adjacent to the concave portion and the outer insulating portion is formed, and the insulating tube is formed with an inner sleeve portion on the tube wall, and the inner surface thereof is convex. [^ φ adult body] may cover the periphery of the insulating layer to be in contact with the expanded portion. The flared portion faces the accommodating groove at the insulating tube, and the groove houses the inner sleeve portion of the insulating tube. In addition, the insulating tube is provided with a transparent window on the tube body for the user to view the torque value output by the torque wrench. 201213064 f The technology, means and functions of the present invention will be described in detail below with reference to the drawings, and it is believed that the above objects, structures and features of the present invention can be obtained from To understanding. [Embodiment] Hereinafter, related embodiments will be described in detail based on the drawings. Please refer to the 1st to 3rd drawings. 'The torque wrench 10 is partially covered with a surface, the edge I 20 is exposed to the insulation | 20 is locked at the end of the adjustment button, and • I is not covered with the insulating layer 2G torque wrench 1G Insulating tube 4〇. In the figure, the torque wrench 10 is a polygonal insertion portion 13' protruding from an insulating-inverted turning button 12' mounted above an annular casing 11, and a hollow support portion 14 is connected to the periphery of the casing 11, and is supported. A torque machine is assembled in the section 14 to be 5 〇. When the turning button 12 is turned, the insertion portion 13 is determined to work in one direction and reversely in the idling; if the slanting button 12' is pressed, the insertion portion 13 can be released from the ferrule (not shown). • The input member of the 1st torque mechanism 50 is a ratchet column 5 that is exposed at the end of the support portion 14 and is locked with the adjustment knob 3〇, and is provided in association with a scale plate 52. When the adjustment knob is turned, the torque value output from the torque column 50 is adjusted by the ratchet column/1 to cause the scale plate 52 to move synchronously along the longitudinal direction of the support portion 14. The insulating layer 20 encloses the outside of the casing u, slightly extending in the direction of the insertion portion, but does not interfere with the operation of the direction change 12, while covering the partial length of the support portion 14 and facing the end of the insulating tube at the insulating layer 2〇 The portion is immersed in the two recesses 21, and the outer expansion portion 22 and the accommodating groove 23 in the form of a 201213064 shape are formed adjacent to the recess portion 21. The receiving groove 23 is recessed into the end surface of the expanded tube 22 toward the insulating tube 40. One of the two tube ends of the insulating tube 40 is formed with two convex portions 42 and an inner sleeve portion 43 on the tube wall 41. These convex portions 42 protrude from the inner surface of the inner sleeve portion, and are inserted into the concave portion 21 at the relative position of the insulating layer 20, while allowing the inner portion The sleeve portion 43 is deeply received by the groove 23 to cover the insulating layer 2, and is sleeved. The periphery of the crucible 43 overlaps with the outer expansion portion 22. The other end of the insulating tube 4 is abutted against the adjusting knob 30, so that the insulating tube 4〇 and the insulating layer 2 are formed in a concave-convex manner to form a body which does not rotate around the supporting portion 14, which facilitates the holding force of the torque wrench 10. The torque value outputted by the torque wrench 10 can be viewed through the window 44 at a position of the tube relative to the scale plate 52. Thus, as long as the insulating tube 40 of the torque wrench 10 is gripped, the electrical resistance can be prevented from being transmitted to the human body, and then the adjustment button 30 is rotated to change the magnitude of the torque, thereby pulling the torque wrench 10 with the insertion portion 13 to work in one direction and reversely idling. For the positive value of the palpitations, just remove the adjustment knob and pull out the insulating tube 40'. Until the calibration is completed, replace the adjustment knob 30 and the insulating tube 40 in sequence. The process is very simple. The above detailed description is only illustrative of the invention and is not intended to limit the invention. Various changes, modifications, and applications derived from the above-described embodiments are within the scope of the invention.
