Description

1221800 发明, description of the invention: The present invention relates to a small tool, including a long body, which is provided as a handle and is provided with at least a receiving portion for a functional element that can be turned out. The force of the anti-elastic element rotates out of the body around a pivot bearing. Such a small tool is, for example, a folding knife, which includes two opposite shells, and between the shells, there are also a plurality of functional parts that can be turned out, such as a blade, a cork screw, a drill, a drill, etc. The impeachment force is supported by turning in or out of sadness. Such small folding knives are known to have different implementations. There are many functional parts that can be pivoted by rivet bolts. The functional surfaces are set as blades, can openers, nail nail cutters, corkscrew, etc. In addition, it is also known to fold # 7 with extremely different tools as functional parts, for example-different sizes of -shaped and Phillips screwdrivers or different size internal and external hexagon wrenches. Such functional parts are arranged between thin plates that are parallel to each other, and are connected to each other by rivet bolts, and the outer thin plates are each covered by a casing. The housing constitutes the appearance of the folding knife on the one hand, and determines the ergonomics and grip of the folding knife on the other. It is also known to provide a push-in channel on the housing, such as a toothpick, a tweezer, or a cleaning needle for a car glass cleaning device nozzle. Folding knives with different functions can also be used in combination with writing instruments. The assembly of such a folding knife is very tedious, so the cost is relatively high. Conventional small tools, especially folding knives, usually have functional elements that can be turned out sideways. The lateral parts protrude beyond the contour of the housing, and can be moved by fingertips. The functional element is pivotally fixed by a spring, so that there is a supporting force in the carrying or storing position of the turning-in and the functional position of the turning-out. The supporting force is

O: \ 68 \ 68662.DOC sexual files are generated, but cannot be controlled. Therefore, the functional element may be returned without endurance during use. In addition, springs can become fatigued over time and are extremely disadvantageous. Another pivotal function of the I-pivoting function μ is that the functional element usually revolves around an axis and can only tolerate a certain degree of torque. And is familiar with the function of small tools: cannot be operated with one hand. Some special folding knife blades can be opened with one hand by loosening a shell / spring, but usually cannot be closed with one hand. Other functional elements can be inserted into and withdrawn from the gap of the casing or body. Small tools are usually and generally: features that are rarely aimed at a particular single purpose because their cost is too high. The object of the present invention is therefore to provide a small tool which has better control of the shear force when carrying or standing, the fatigue of the elastic element will not have an adverse effect, the manufacturing cost is low, and the operation is easy. This object is achieved as follows: the elastic element abuts the base of the functional element, and at least the two are provided with mutually protruding protrusions and depressions. According to the present invention, the functional element is provided as a rotatable member which is resistant to the force of a spring and can be placed in a carrying position folded into the body and folded out of the body to stand up and turn. The spring-on the one hand, provides-support :: to prevent inadvertent folding out, and on the other hand--force in the folded out functional position to prevent inadvertent folding. The base of the functional element can be moved in a conventional manner against a shrapnel. Suggested function at the base of the component. "One to two years old bumps and Shen, Niu, Niu at least 5 and another bumps, another element is provided with a sinker, the bump is embedded in the sinker when the final position is reduced. This can improve the support force. : It is provided with a protrusion, which sinks into the sinker's subsidence when it is folded out. Here, the sinker is preferably provided at one end of the impeachment guide track. Advantageous

O: \ 68 \ 68662.DOC 1221800 is provided with a protrusion at the base of the carrying position and functional position, which can be embedded in the corresponding depression of the elastic yellow. In this way, the support force can be restrained and set by the size of the protrusions and subsidences, so that even if the spring is fatigued, sufficient support force for the functional elements can be ensured. Therefore, the functional element can be prevented from being inadvertently folded back during use. The base portion can be exchanged with the protrusions and depressions on the spring element. The free end of the spring element can also be embedded in a groove-shaped deep depression, so that the support force for preventing the functional element from being unintentionally folded back during use is particularly high. Randomly operating the folding knife may cause the folding knife to be accidentally turned back and cut the fingers holding the body. The invention further proposes that the function element that can be turned out can be elastically pressed into the body at the position where it is turned into the body ', which can also be adapted to the design of the protrusions and depressions. The invention has low manufacturing cost and simple operation, and can be operated with one hand in particular. The design of the bumps and depressions between the functional element and the spring improves the safety in use and improves the functionality, as it can be avoided from accidentally turning back during use. To improve the economy, the present invention further proposes to further improve the spring. The conventional bomb I needs to be on the thin plate relative to the supporting building. Here, the protrusion is only provided with a protrusion at an appropriate position. The protrusion can be supported relative to the protrusion of the adjacent spring. Support point. For other advantages and features of the present invention, refer to the description of the following drawings: Figure IX is an embodiment of the configuration of the protrusions and depressions between the blade base and the spring. Fig. 2 shows another embodiment of the configuration of the protrusions and subsidences between the blade base and the impeachment. Figure i shows an embodiment of a functional element W set as a knife saw configuration 2. The knife mine

O: \ 68 \ 68662.DOC 1221800 Configuration 2 can be revolved-the pivot bearing 3 is turned out from a body not shown to the functional position: the dragging part is set at the base part 4 of the functional element 1, and as shown in the figure, Looking at the function and the line, the center and longitudinal lines of the functional part can be turned out, and the pivot bearing 3 is eccentrically provided. This is conducive to withstanding torque. The spring 5 showing only the end has an end 6 provided with a convex portion and a sunken portion. In the functional end position, the protrusion is embedded in one of the grooves of the base 4, and a corresponding protrusion on the base is embedded in the recessed portion of the spring 5. In this way, the supporting force and the force required for positioning are controlled. The spring travels along the movement track 9 with its free end and snaps the projection 8 of the base 4 to increase the support force when turning into the state. Figure 2 shows the control and improvement of the support force of the pivotable functional element. The base 30 of the blade 27 and the corresponding end of the spring 28 which can be pivoted about the shaft 29 can be seen in FIG. When the functional element 24 is in the position shown in Fig. I, the blade 27 with its stationary braking portion 31 abuts against the spring 28 stationary braking portion 32. In the embodiment shown, the protrusions 33 of the blade base 30 are embedded in the spring recesses 34. So depending on the size of the protrusion 33 and the spring: in the blade carrying position, that is, the turning position, an appropriate supporting force is generated. Angle 35, for example at 22. To 37. Between 'determines the force required to move the protrusion 33 away from the sinker 34. The angle% of the subsided portion 34 needs to be properly matched, for example, at 20. To 35. between. Applying force to the blade to overcome the supporting force causes the protrusion B to be moved away from Shen 1¾ # 34 # ′ The outermost movement path 37 of the blade base slides over the static braking portion 32. This sliding guide allows the blade 27 to be smoothly ejected toward the bullet. Finally, the base of the blade, designated 38 in the embodiment, protrudes into the depression 39 of the other edge of the spring. The height of the braking portion 42 defines the position of the blade that is turned out. Here, the blade base 30 is raised, 38 degrees, and the lazy spring 28 is sunk. The angle 41 is also matched with each other, for example, both are about 6G. . In this way, an appropriate supporting force for supporting the blade 27 in the turned-out position is obtained, so that the blade does not
