Description of the new type: The technical field of the new type] ‘More specifically, it refers to the type of locking nut used with the collet related to the accessories of the drilling tool set. [Previous technology] The general lock nut 1 and the flexible collet 2 are unbearable. 'The lock nut i has a shaft hole 1 & and: two threads le are formed around the upper section of the inner ring surface lb, the The internal thread ^ can be matched with the outer shank (not shown) of the arbor (not shown), — convex = = ”_ 彡 成 有 —horizontal support — and _ directional clip 2 penetrates inside-connection hole 2 and most Longitudinal groove-phase of the joint 2a; with cool = 15 20 characteristics, in addition, the near-bottom part of the collet 2 has an outer diameter, neck & 2e, and-horizontal abutment surface 2d and copper section ^ Connection; When assembling, first place the collet 2 in the lock nut 丨 the shaft hole of the collet 2 is the same as the neck 2c of the clip 2 and the convex nut i: = it is in abutting shape with the catching surface k, and then, When the lock nut 亥 = 1c is screwed with the external thread of the tool bar, and the upper part of the collet 2 is in the middle, 'the lock nut 1 may be tightened when the lock nut 1 is continuously tightened. The purpose of clamping tools is achieved, but in the case of both the tapered hole of the tool bar and the lock nut! D ^ The lock nut 丨 not tightening the process towel will make the abutment 2d Bird face le Ground friction, * After repeated disassembly -4- M270871, it is easy to cause wear on the contact surface. When the abutment surface 2d of collet 2 is worn, in order to avoid errors after assembly, it is not appropriate to cooperate with other It is necessary to replace the lock nut with a new collet, but this will increase the cost. 5 In view of this, the creator of this case has carefully considered and has been engaged in the development and manufacturing of related industries for many years. Experience has resulted in this creation. [New content] The main purpose of this creation is to provide a lock nut that can avoid abrasion of collets with 10 sets. In order to achieve the above purpose, this creation A locking nut is provided for use with a tool collet, and includes: a body having a shaft hole and an inner ring surface, a thread section provided on the inner ring surface, and a ring-shaped groove A recess is formed from the inner annular surface in a radial direction; a bushing is embedded in the 15 slot, and the bushing has a perforation for the collet to pass through. [Embodiment] Hereinafter, the comparison of this creation is enumerated. Best embodiment The following diagrams are explained in detail below. Among them, the first picture is a schematic diagram of the use of a general elastic collet and a lock nut. The second picture is an illustration of a lock nut component in a preferred embodiment of the present invention. Sectional view of the elastic collet. The third and third figures are sectional views of the locking nut and elastic collet of this creation. -5- M270871 The fourth figure is a partial enlarged view of the second figure. The fifth figure is the locking nut of this creation. A cross-sectional view of the assembly of the cap and the elastic collet. Please refer to the second to fifth figures. This creation—the preferred embodiment of the lock 5 screw cap is used to lift the elasticity of the knife with a face knife to form a solid knife (not shown). The tube loss 20 is used in combination with 'the collet 20 has a neck section with a reduced outer diameter' and an abutment surface 24 connected to the neck section 22, and the lock nut 10 is composed of a body 12 and a spacer 14 The body 12 has a shaft hole 121 and an inner ring surface 122, and a threaded section 1023 is provided at the upper position of the inner ring surface 122. The threaded section 123 can be externally threaded with the tool bar (not shown in the figure). (Shown) screwing, because the arbor is not the improvement target of this creation, not described in detail here, a ring-shaped slot 124 The inner ring surface 122 is formed in a radial depression, and the latching groove 124 is located below the threaded section 123. In addition, the main body 12 is formed with a ring stop 125 on the top edge of the latching groove 124 and a latching groove at I5. The bottom edge of 124 has a horizontal blocking surface 126. It is further noted that the hole diameter of the body 12 at the threaded section 123 is larger than the hole diameter of the card slot 124, and the hole diameter of the card slot 124 is greater than the hole diameter of the stop 125. The backing ring 14 is made of an abrasion-resistant material, and its thickness is about the same as that of the slot 124, and the outer diameter of the backing ring 14 is slightly smaller than the hole diameter of the body 12 at the slot 20. The backing ring 14 The middle part has a tooth hole I43 ′ penetrating the top surface 141 and the bottom surface I42, and the outer peripheral surface close to the top edge part has a convex protrusion 144 integrally made as a microprojection. The outer diameter of the liner 14 on the convex protrusion 144 is larger than that of the body 12. The hole diameter of the retaining wall 125 is smaller than the hole diameter of the 124 slot of the main body 12, as shown in Figure 4. The convex wall M4 has an inclined guide surface, so when assembling, • 6 · M270871 only needs to apply a large external force. The backing ring 14 can be embedded in the slot 124 so that the bottom surface 142 and the stop surface 126 of the backing ring 14 are attached, and the projection 144 is limited by the backing 125, which can prevent the backing ring 14 from facing each other. The main body 12 ′ is detached: As shown in FIG. 4, the spacer 14 is disposed in the main body 12 5 in a freely movable manner. Second, as shown in Figure 5, when the locking nut 1G of this creation passes through the perforation 143 at the 20W section of the elastic cylinder center, the inner edge of the collar 14 and the collet 20 neck section 22 form an engagement, At this time, the abutment surface 24 of the collet 20 and the top surface of the lining ring 14 are in contact; when the body U is screwed with the external thread of the tool bar by its thread section 123, `` because the outer diameter of the ring 14 is smaller than the body 12 The hole protection at the slot 124 makes the body 12 in the pin ground, and the lining ring 14 * will not cause wear to the collet 20 relatively as the body 12 rotates. Therefore, this creation has progress and practicality in similar products, and there is no identical item in this creation before the application. Seen in the publication or on the 15th, ‘this creation already has the elements of a creation patent, and it is submitted according to law. Yun Wei, the above is only the creation of this creation-the best feasible embodiment, so 'all examples of this copy _ instruction manual and towel material _ are equivalent, Q structure changes, should be included in the scope of this creation's patent Inside. 20 -7- M270871 [Brief description of the diagram] The picture of a younger brother is a picture of a boat. * The schematic diagram of the collet used with the lock nut.
