Description

M258826 IV. Creation Instructions (1) [Technical Field of New Type] This new type is related to a wrench, especially a high precision, fast manufacturing speed, low cost, and can increase the size and thickness of the wrench without the need for secondary mold manufacturing. Improved wrench structure. [Prior art] For the known wrench structure, please refer to the "Multipurpose Quick Wrench Pliers" of the Republic of China Patent Bulletin No. 3 8 8 3 1 4 which consists of a movable pliers block, a lever and

It consists of an elastic element. The pole of the plate is inserted into the clamping slot of the movable sweet block. The pivot hole of the pivot block is provided with a receiving slot for receiving the elastic element. The elastic element is fixedly inserted. The insertion end is inserted into the jack of the pivot block, and the movable extension end is inserted into the groove wall limit groove of the movable pliers block; the conventional wrench structure, the movable pliers block and the lever are

,…--..... v 脰 Wind I has a larger thickness, it is difficult to cut deeper and clearer teeth. After long-term use, it is prone to wear and tear. The wrench is made by forging, so it has the problem of poor manufacturing accuracy. & No lx is thinner, and cut out the groove in the movable pliers block :::: The knife lever is cut and pivotally connected to the lever. This structure can be set and easily generated when the force is applied to rotate the screw. Fracture and deformation, and more cutting by the lever | 'Due to the large forces, the lever is thinner, the structure is weaker and more holey. When the size and thickness of the bullet are installed, a second mold is required for manufacturing ， 贝 ， 'and the desire to increase [new content] Wen Yue added the cost of manufacturing. The main purpose of the new model is to solve the above-mentioned shortcomings and avoid them.

Page 5 M258826 Fourth, the existence of the creation description (2) 'This book is made fast to reach a pressure space between the pliers body parts, and the end surface is provided with a screw so that the screw can be pressed; to extend in the assembly space The body presses the spring. Because the above assembly is cut out and the assembly is empty; the structural strength is also not required after cutting. This new type with different sizes and thicknesses is provided and manufactured for the stated purpose. 'The system consists of two assembly spaces, a jaw system consisting of several first-to-back pressure air and an elastic parallel contact elements. It is strong, and there is no room to improve the structure of a wrench with a wrench, so that the accuracy of the wrench is low. The structure improvement of the new wrench includes: a symmetrically structured first plate, a second jaw for pivoting, and a second plate with the pliers, and the teeth of the first plate. The jaw body has a matching second interdental tooth and is clamped by the above-mentioned first and second tooth parts. One end of the jaw body is fixed to the jaw body, and the other is to the rhyme body, so that the jaw body rotates relative to the jaw body and generates elasticity The restoring force is used to make the jaw high, ~ the turning part, the turning degree of the body when the turn is turned, and the lack of improvement. The stamping method is used to make the desired shape. For example, if the system is made by forging, the new cutting process requires better precision and speed, and the above-mentioned teeth are deeper after finishing. The problem arises, $ 'accommodates the elastic element, so increasing the structure of the mold can increase the number of pieces to increase: =: factory: 1 and:;: strong, if you want to change the size of the wrench The thickness requires two: under

[Embodiment] The detailed description and technical contents of the new model are as follows: Now, please refer to the diagram to take the diagram symmetrically, and the two first rods 20 assembly air system and the 30th support group. "1 2", which is the appearance of the new model and the eight classics such as f *. The new model includes:-clamp body 1, which is composed of two structural plates 11 to form an assembly space 丨 丨 3; hunting Therefore, the first plate 11 and the second plate 21 are composed of two second plates 21 having the same structure, and are used to form a turning space between the jaws and "3" and the forceps m. 12, and two marks: one piece, one piece, one piece, the front end of the assembly portion 112 is equal, and a plurality of second rods are used to set up a plate 11 and a support plate 4 in the empty space of the group 11 3 Among them, the end portion U 2 of the first plate 11 and the end face of the supporting plate 4 have several first teeth 114, 41, and the second plate 21 of the jaw 2 has / matches the first teeth 11 4, 4 1 The second tooth portion 2 11 is used to place the screw (not shown) in the pressure space 1 2 and use the first and second tooth portions 丨 丨 4, 2 丨 丨 to clamp Turn, screw And an elastic element 3, which has a fixing portion 31 that can be straddled over the handle portion 1 1 1 of the two first plate members 1 1 and penetrates the handle portion through a third rod member 4 and the fixing portion 31 is fixedly installed, and extends from the fixing portion 3 丨 to the assembly space 丨 3 and contacts the top stop portion 32 of the jaw body 2. In addition, a tooth member 5 is provided on both sides of the second plate member 21 of the jaw body 2 and also has the same second tooth portion 51 as the above. A second plate is penetrated through the fourth rod member 50.

M258826 Fourth, the creation instructions (4) pieces 21 and 5, to fix the tooth 5 to the second plate. To assist in holding the screw, and finally a handle sleeve 10 is set on the handle of the first plate 丨 丨 丨 i for a user to hold more comfortably, and because of the handle 丨 丨 丨 and The first plate is at an angle, making the handle sleeve 10 difficult to fall off. Please refer to "Figures 3-1, 3-2", which is a schematic diagram of the operation of the new model. As shown in the figure, the jaw body 2 is centered on the first rod 20 and rotated relative to the forceps body 1 to The turning pressure space 12 is opened to lose the screw (not shown in the figure). At this time, the jaw body 2 will press the top stop portion 32 of the elastic element 3 to make it elastic.

The restoring force pushes against the jaw body 2 to return the jaw body 2 to its original position to close the turning pressure space 12. Refer to "Figure 4", which is a schematic diagram of another embodiment of the present invention. As shown in the figure, the structure is substantially the same as the above. The jaw body 2 is pivoted to the installation space 113 'in another direction. Those who constitute another form of use. In addition, when it is desired to change the size and thickness of the wrench, the angle of the assembling portion 112 extending outwardly from the first plate 丨 丨 can be increased, thereby increasing the size of the assembly space by 1 u, and adding a supporting plate 4 and the number of teeth 5 are clamped by the first plate 11 of the pliers body 1 to increase the size and thickness of the wrench.

To sum up, it is only the preferred embodiment of the present invention, X, and it is not used to limit the implementation scope of t. That is to say, all equivalent changes and modifications based on the scope of the patent application for the new model shall be the technical scope of the new model. Lu
