New description: [New technical field] This creation involves the protective insulation technology of tools, especially a ratcheting torque tool that can be waterproof and insulated. [Prior Art] A wide variety of common loosening and locking tools, mostly wrenches and screwdrivers. As far as the starter is concerned, whether it is the initial stage of the unscrewing stage or the end of the locking stage, the torque value is often output by personal experience, but it is easy to exceed the load that the workpiece can bear, resulting in the collapse of the screw. In order to reduce the chance of chipping, tool makers have developed a torque tripping mechanism. As the name implies, if the torque transmitted by the screwdriver exceeds the preset torque value, the torque will be interrupted and the output will be interrupted to avoid unnecessary damage. For example, Taiwan's invention No. 101112479 has revealed one of many torsion jumping mechanisms. However, these screwdrivers with a torque tripping mechanism contain metal-made components and are prone to electric shock and casualties when working in the electrical field. Therefore, how to reduce the incidence of electric shock for the torque driver disclosed in the application No. 101112479 of Taiwan Invention has become an urgent problem to be solved in this creation. [New content] In view of this, the creator has in-depth discussion of the problems of the prior art. With many years of experience in R&D and manufacturing of related industries, he actively sought 3 M441552 to find a solution, and finally successfully developed a ratchet that can be waterproof and insulated. Twist the screwdriver to improve the problem of the habit. The main purpose of this creation is to construct an isolated protective cover around the torque driver, which can reduce the incidence of electric shock and provide insulation safety even when the electrical equipment performs locking or unscrewing operations. Due to the above object, the present invention provides a waterproof and insulated ratchet torque driver, comprising: a non-conductive grip member having a receiving compartment recessed at the front end of the grip member; a large diameter portion and a small diameter portion communicating with each other, the front end of the grip member is connected by the cover body, so that the large diameter portion covers the outer periphery of the front end of the grip member; and a torque tripping mechanism is arranged in the cover body and the grip holding chamber An insulating rod, the insulating rod and the torsion jumping mechanism have a transmission relationship, and extend a certain length outward through the small diameter portion of the cover body; a 0-shaped ring, an 0-shaped ring is arranged in the large-diameter portion of the cover body and holds Between the front ends of the pieces, another 〇-shaped ring is interposed between the small diameter portion of the cover body and the insulating rod. · The insulating rod is selected from one of the following structures: “Yangchun type”, a main shaft having a transmission relationship with one end of the torsion jumping mechanism, a multi-angle groove formed at the other end of the main shaft, and an insulating sleeve, the insulating sleeve Wrap the outside of the spindle. "Essence type" A main shaft, one end of which has a transmission relationship with the torsion jumping mechanism, 4 M441552 main shaft is formed with a small diameter insertion section at the other end; a front shaft has a sleeve groove at one end thereof, which is forced to the insertion section, front A multi-angle groove is recessed at the other end of the shaft; and an insulating sleeve encloses the outer surface of the combination of the main shaft and the front axle. In this way, from the insulating sleeve to the insulating cover, with the non-conductive grip, the isolated protective cover is constructed on the periphery of the torque driver, which can reduce the occurrence of electric shock even when the electrical device performs locking or unscrewing work. # rate, with insulation safety features. Hereinafter, the purpose, structure and characteristics of the related embodiments will be described in detail based on the drawings, and it is believed that the techniques, means and effects adopted by the present invention can be understood in detail. [Embodiment] Please refer to Figures 1 and 2 for the specific structure of the torque driver 10. The torsion driver 10 has a gripping member 12, and the front end 14 of the gripping member 12 is joined to a joint member 20, and the tail portion 22 is not separated, so that the connecting member 20 rotates in the same direction as the gripping member 12. The head portion 24 of the connector member 20 is recessed into a receiving chamber 26, and a cover 40 that is locked to the head portion 24 forms a receiving space sufficient for collecting a torque tripping mechanism 30. The torsion tripping mechanism 30 includes two engaging members 32, wherein one of the engaging members 32 is in rolling contact with the cover 40 via a set of bearings 34, and a spring 36 is sandwiched between the other engaging member 32 and the deep wall of the receiving compartment 26. The force required for the two engaging members 32 to maintain the engaged state is provided. As for the detailed structure and characteristics of the torsion jumping mechanism 30, it belongs to the claim of the invention patent No. 101112 4 7 9 patent, and is not the core of the creative technique 5 M441552, and will not be described here. The cover 40 is made of an insulating material and has large and small diameter portions 42, 44 communicating with each other inside. The large-diameter portion 42 accommodates the head portion 24 of the connecting member 20, and has a covering function of a partial periphery of the front end 14 of the grip member 12, and a ring-shaped ring 46 is disposed between the large-diameter portion 42 and the front end portion 14. The small diameter portion 44 is disposed outside the insulating rod 50, and another ring-shaped ring 46 is disposed between the small-diameter portion 44 and the insulating rod 50. These cymbal rings 46 are stretched and elastic, and are bound to the outer surface of the grip member 12 and the insulating rod 50 to prevent external dust or liquid from entering the torsion jumping mechanism 30, and have the effects of preventing water and dust. In the present embodiment, the insulating rod 50 is composed of a main shaft 52, a front shaft 60 and an insulating sleeve 70. The main shaft 52 end of the figure is integrally formed with the engaging member 32 away from the grip member 12, and a ring groove 54 is recessed near the torsion jumping mechanism 30, and the concave and convex fits a fitting portion 72 which is raised on the inner surface of the insulating sleeve 70 to prevent The insulating sleeve 70 is separated along the length of the main shaft 52. A small diameter insertion section 56 is formed at the other end of the main shaft 52. The diameter is self-tightened and recessed in the sleeve groove 62 of the front axle 60, so that the front axle 60 does not rotate relative to the main shaft 52, but can move in the same direction as the main pumping 52. To transmit the torque of the grip member 12. The front shaft 60 is different from the end surface of the main shaft 52 by a polygonal groove 64. The groove receives a workpiece of a shape corresponding to the drawing (not shown), such as a screwdriver head, a connecting rod or a sleeve, and performs the loosening and locking operation. . Of course, the polygonal groove 64 is configured to fit the concave-convex portion of the workpiece, and can also be applied to the portion of the front shaft 60 that is coupled to the insertion portion 56. The insulating sleeve 70 is made of an insulating material and encloses the outer surface of the combined body of the main shaft 52 and the front axle 60. A small groove 74 is formed in the small diameter of the insulating sleeve 70 into the cover 40 of the cover 40 to accommodate easy separation. position. 0-ring 46 will not be light :..., in a torque driver;:= not low incidence of electric shock, full characteristics when insulated.
