Description

  The present invention relates to a general-purpose dovetail sliding unit, and in particular, a general-purpose that adjusts the position of an attached precision instrument by fitting a part having a dovetail and a part having an dovetail and sliding the handle by operating a handle. The present invention relates to a dovetail sliding unit.

  Precision devices such as electrical devices such as CCD cameras and sensors, optical devices such as lenses and microscopes, and illumination devices such as LEDs must be adjusted for positioning and focusing. Further, there may be a case where the position is further finely adjusted after the attachment.

  These precision instruments are installed and adjusted on a machine element generally called a “stage”. The dovetail sliding unit is a kind of this “stage”. FIG. 10 shows a general configuration of the dovetail sliding unit. In the dovetail sliding unit 100, a sliding unit 104 having a trapezoidal dovetail 101 is movably fitted to a fixed unit 105 having a trapezoidal dovetail groove 102. The fixing unit 105 is fixed to a base (not shown) through a base 103 having a fixing hole 106. The sliding unit 104 is connected to a precision device (not shown) via a bolt (not shown) inserted into the precision device mounting hole 107. The sliding unit 104 moves in the direction of the arrow in the figure by rotating the handle 109. The amount of movement is measured by a pair of scales 108. This is because a drive mechanism using a feed screw (not shown) or a rack and pinion (not shown) is incorporated in the dovetail sliding unit 100. By these driving mechanisms, the rotation of the handle 109 is converted into the movement of the sliding unit 104 in the horizontal direction. Thus, the dovetail sliding unit 100 is a stage having a sliding mechanism in one direction.

  The dovetail sliding unit 100 using the feed screw type drive mechanism moves about 4.2 mm by one rotation of the handle, has high load resistance, and is suitable for fine adjustment. On the other hand, the dovetail sliding unit 100 using the rack and pinion type drive mechanism is suitable for a case where the handle moves about 18 mm by one rotation of the handle and needs a quick and large movement. Further, the dovetail sliding unit 100 is generally subjected to position adjustment in two stages, that is, coarse adjustment by the handle 109 and fine adjustment by screws.

  The dovetail sliding unit 100 is required to be versatile in order to meet the various uses described above. The dovetail sliding unit 100 is a highly versatile stage with respect to a single slide function by adapting such a simple external shape and bolt mounting position to meet this requirement. Also, there are types for basic operations such as horizontal direction (X axis, Y axis) sliding and height direction (Z axis) sliding, and special application types such as column mounting and CCD camera mounting. On the other hand, a dovetail sliding unit 100 having a sliding mechanism in two directions (X, Y) or three directions (X, Y, Z) at the same time is required by combining these types for basic operation and special applications. There is a case. In order to meet this requirement, a multi-function dovetail slide unit in which two or three or more dovetail slide units 100 are connected is conventionally used.

  In FIG. 11, the structure of one Example of a multi-function dovetail slide unit is shown. In this multifunctional dovetail sliding unit 200, an upper unit 202 that slides in the left-right direction in the figure (the direction of the arrow in the figure) and a lower unit 203 that slides in the vertical direction in the figure have an adhesive surface 206. Therefore, it is joined by the fastener 201 and an adhesive. FIG. 11 shows a state in which the sliding unit 204 of the upper unit 202 is slid to the left side of the drawing. The fixing unit 205 of the upper unit 202 is provided with a hole for the fastener 201, and the sliding unit of the lower unit 203 is provided with a fastening hole 207 for the fastener 201. The fastener 201 is a one-side bolt in terms of the mechanism of the dovetail sliding unit 100, and is a screw-in type fastener 201 that does not use a nut and a washer, unlike a normal bolt. For this reason, in order to prevent the screws of the fastener 201 from loosening or coming off due to vibration or impact generated from the precision device to be attached, an adhesive is injected into the fastening hole 207 when the fastener 201 is attached. Is fixed.

  In the case of this multifunctional dovetail sliding unit 200, the fasteners 201 to be joined are joined in a state where any dovetail sliding unit 100 of the dovetail sliding units 100 to be joined is slid. That is, in the case shown in FIG. 11, the fastener 201 is inserted from the sliding unit 204 side facing the fixed unit 205 of the lower unit 203. Therefore, when the fastener 201 is inserted, the sliding unit 204 of the lower unit 203 must be slid until the fastening hole 207 appears.

  Further, the dovetail sliding unit 100 is required to have a high degree of accuracy for positioning and focusing, and at the same time, a smooth and quick sliding performance is required. The fitting part between the dovetail groove 102 and the dovetail 101 shown in FIG. 10 which is a precision part requiring high accuracy is assembled by surface contact or scrutiny technology using craftsmanship. Therefore, it is difficult for the user to disassemble and reassemble these multifunctional dovetail sliding units 200 into a single dovetail sliding unit 100. That is, accuracy cannot be secured even if the adhesive injected into the fastening holes 207 of the plurality of dovetail sliding units 100 is peeled off and joined again. Further, the attachment position of the fastener 201 is provided at a position where it cannot be removed unless the dovetail sliding unit 100 is slid due to its mechanical limitations. Accordingly, the fastener 201 must be attached and detached by operating a precision part (a fitting portion between the dovetail groove 102 and the dovetail 101), and a user who does not have a craftsman's surface contact or rubbing technique is highly skilled. It is difficult to do this with accuracy.

JP 2003-42154 A

  The dovetail sliding unit is required to be versatile as described above. However, in the multi-function dovetail slide unit in which the fastener of the dovetail slide unit is joined by an adhesive, it is difficult for the user to peel it off and assemble, and the combination of joined functions is limited and changed. Can not. That is, the dovetail sliding unit has versatility with a single function, but loses its versatility due to multi-function. In addition, for example, the multifunction dovetail sliding unit has a problem that the direction of the handle is fixed and the usability is poor. For this reason, there is a possibility that the user peels off the adhesive that fixes the multifunctional dovetail sliding unit by itself, and the accuracy after assembly is lowered, and the user cannot use it.

  In addition, the dovetail sliding unit is required to have a high degree of accuracy as described above. However, when the dovetail slide unit is used as a multifunctional dovetail slide unit, the use of one slide mechanism may cause a problem that the other slide mechanism is subjected to vibration and the accuracy of the position cannot be ensured. In particular, depending on the usage conditions of precision equipment, there may be a problem that an impact occurs and the fastener is unscrewed or damaged.

  Further, by combining a plurality of dovetail sliding units, each dovetail sliding unit receives a complex eccentric load as described later. Accordingly, the dynamic vibration generated by the operation of one slide mechanism may cause a problem that the other slide mechanism is subjected to dynamic eccentric bending, and the fastener is loosened or fatigued.

  Further, by combining a plurality of dovetail sliding units, each dovetail sliding unit receives a horizontal load in two directions as will be described later. Therefore, the dynamic vibration generated by the operation of one slide mechanism may cause a problem that the other slide mechanism receives a dynamic horizontal shearing force, and the fastener is loosened or twisted.

  The purpose of the present application is to provide a universal dovetail sliding unit that solves such problems and ensures versatility and accuracy when the dovetail slide unit is used as a multifunctional dovetail slide unit. .

  In order to achieve the above object, the general-purpose dovetail sliding unit according to the present invention is a position of a precision instrument attached by fitting a part having a dovetail and a part having an dovetail and sliding the handle by operating a handle. A plurality of dovetail slide units for adjusting, a plurality of dovetail slide units each having a different function, a connecting part having a fastening hole and connecting the plurality of dovetail slide units, and a dovetail slide And a fastener for detachably fixing the unit and the connecting part, and a buffer material fixed inside the fastening hole is provided in a gap between the fastening hole of the connecting part and the fastener. .

  In the general-purpose dovetail sliding unit, the fastener has a head portion and a screw portion, and the fastening hole of the connecting part houses the head portion of the fastener, and includes a side surface and a bearing surface that supports the fastener. It is preferable that the head storage unit is provided and the cushioning material is provided in the head storage unit.

  Moreover, it is preferable that a buffer material is provided in the side surface and bearing surface of a head accommodating part as for a general purpose dovetail groove sliding unit.

  Further, the general-purpose dovetail sliding unit has a fastening hole provided in the connecting component, a hole obtained by cutting the edge plate surface of the fastening member into a U-shape, and a hole from the opening side of the U-shaped hole. It is preferable that it is the cylindrical hole formed by the components inserted in.

  In the general-purpose dovetail sliding unit, the buffer material is preferably a viscoelastic material.

  Moreover, as for a general purpose dovetail groove sliding unit, it is preferable that a viscoelastic material is provided in the surface of a connection component.

  Further, in the general-purpose dovetail sliding unit, it is preferable that the connecting component is composed of a plurality of stacked components, and a viscoelastic material is provided between the components.

  With the above configuration, the general-purpose dovetail sliding unit can be detachable with a fastener using a connecting part. This is because the conventional multi-function dovetail sliding unit joins the dovetail sliding units with a fastener and fixes the fastener to the fastening hole using an adhesive. By providing a cushioning material fixed inside the fastening hole in the gap between the fastening hole of the connecting part and the fastener, the user can fit the precision part of the dovetail sliding unit (the fit between the dovetail and the dovetail). The dovetail sliding unit can be assembled freely without touching the part). For example, the direction of the handle can be easily changed. That is, when the dovetail sliding unit is used as a general-purpose unit, its versatility can be ensured.

  Further, the buffer material provided in the gap between the fastening hole of the connecting part of the general-purpose dovetail sliding unit and the fastener may be a viscoelastic material, and can absorb vibrations generated in the attached precision device. That is, vibration generated in precision equipment, particularly impact energy, is absorbed and attenuated as thermal energy by the viscoelastic material. Thereby, when the dovetail sliding unit is used as a general-purpose unit, it is possible to ensure the accuracy.

  As described above, according to the general-purpose dovetail slide unit according to the present invention, the dovetail slide unit can be used as the general-purpose dovetail slide unit while ensuring the versatility and accuracy.

  Embodiments according to the present invention will be described below in detail with reference to the drawings.

  FIG. 1 shows a schematic configuration of one embodiment of a general-purpose dovetail sliding unit according to the present invention. FIG. 1A is a plan view of a general-purpose dovetail sliding unit 1 that slides in the XY directions shown in the figure, and FIG. 1B is a side view seen from the AA direction. 1 (c) is a side view seen from the BB direction. The general-purpose dovetail sliding unit 1 includes an upper unit 2 that slides in the X direction, a lower unit 3 that slides in the Y direction, and a connecting component 6 that connects the upper unit 2 and the lower unit 3.

  The upper unit 2 and the lower unit 3 are dovetail sliding units 100 each having a single function. The sliding unit 4 and the fixed unit 5 are fitted to each other, and the sliding unit 4 handles the fixed unit 5. Slide by 9 turns. The connecting part 6 is provided with four upper unit fastening holes 7 for connecting to the upper unit 2 at four locations. The connecting component 6 is provided with four lower unit fastening holes 8 for connecting to the lower unit 3. A hexagon socket head bolt 12 (see FIG. 2), which is a fastener, is inserted into these fastening holes 7 and 8 and screwed.

  As shown in FIG. 1A, by providing the connecting component 6, the user can attach each hexagon socket head bolt 12 without sliding the sliding unit 4. First, the connecting part 6 is set on the upper part of the lower unit 3, and the hexagon socket head cap screw 12 is inserted and fixed into the lower unit fastening hole 8 from the upper side of the connecting part 6. Next, the lower unit 3 to which the connecting component 6 is attached is turned upside down, and the upper unit 2 is set from above. At this time, the upper unit fastening hole 7 of the connecting component 6 is exposed to the outside. Accordingly, the hexagon socket head cap bolt 12 can be easily fixed from above the connecting component 6. For example, when the user changes the direction of the handle 9 of the upper unit 2 or the direction of the handle 9 of the lower unit 3 to the opposite direction, the general-purpose dovetail sliding unit is operated by the operation reverse to the above-described operation. 1 can be disassembled and reassembled. Also in these operations, disassembly and assembly are possible without sliding the sliding unit 4 of the dovetail sliding unit 100.

  In FIG. 2, the enlarged plan view and sectional drawing of one Embodiment of the connection component 6 which concern on this invention are shown. FIG. 2A is a plan view of the connecting component 6, FIG. 2B is an AA cross-sectional view thereof, and FIG. 2C is a BB cross-sectional view thereof. The connecting component 6 connects the upper unit 2 and the lower unit 3 with hexagon socket head cap bolts 12. The hexagon socket head cap screw 12 includes a head portion 15 and a screw portion 19. The connecting part 6 is provided with an upper unit fastening hole 7 so that the hexagon socket head bolt 12 is inserted from the opposite direction to the upper unit 2. The connecting component 6 is provided with a lower unit fastening hole 8 so that the hexagon socket head cap screw 12 is inserted from the opposite direction to the lower unit 3. That is, the fastening holes 7 and 8 are provided so that the heads 15 of the hexagon socket head cap bolts 12 are provided in the connecting component 6. This means that the upper and lower dovetail sliding units 100 need only have female screws for the hexagon socket head cap bolts 12 cut. Moreover, the function of the connection between the upper unit 2 and the lower unit 3 means that the connecting part 6 is integrated. As a result, the heads 15 of the hexagon socket head cap bolts 12 are all stored in the fastening holes 7 and 8 provided in the connecting component 6.

  FIG. 3 shows an enlarged cross-sectional view of the upper unit fastening hole 7 of the connecting component 6 and the hexagon socket head cap bolt 12 inserted into the upper unit fastening hole 7. The fastening hole 7 for the upper unit of the connecting part 6 is smaller than the cylindrical portion 17 having a larger diameter for accommodating the head portion 15 of the hexagon socket head bolt 12 and the screw portion 19 of the hexagon socket head bolt 12. And a cylindrical portion 27 having a diameter. In the upper unit fastening hole 7, a viscoelastic material 10 attached to the inner surface of the cylindrical portion 17 and a viscoelastic material 20 attached to the bottom surface 18 which is a bearing surface are fixed. That is, the film-like viscoelastic material 10 is formed into a cylindrical shape with an adhesive applied to the outside thereof, and is attached to the inner surface of the columnar portion 17 of the upper unit fastening hole 7. Further, the film-like viscoelastic material 20 is applied to the bottom surface 18 which is a bearing surface of the cylindrical portion 17 with an adhesive applied to the lower surface. After the viscoelastic materials 10 and 20 are attached, the hexagon socket head cap bolt 12 is inserted into the upper unit fastening hole 7 and screwed into the screw hole provided in the fixed unit 5 of the upper unit 2. When the hexagon socket head bolt 12 is screwed in, the viscoelastic materials 10 and 20 receive a compressive force on the surface thereof, and come into close contact with the connecting part 6 and the head portion 15 of the hexagon socket head bolt 12. The above configuration is the same for the lower unit fastening holes 8 of the connecting component 6.

  The viscoelastic materials 10 and 20 are polymer materials that have a mechanical behavior that has both fluid-like viscosity and spring-like elasticity, and chloroprene rubber, silicone rubber, or the like is used. The viscoelastic materials 10 and 20 are also called high damping rubber, and the material itself has damping performance. That is, when stress is applied to the viscoelastic materials 10 and 20, energy of vibration and impact is absorbed by the non-linear behavior accompanying the load history, and mainly converted into thermal energy. In particular, when the sheet-like viscoelastic materials 10 and 20 receive a shearing force in the plane thereof, they cause shear deformation and energy absorption, thereby attenuating stress generated by vibration or impact.

  The general-purpose dovetail sliding unit 1 is attached to a precision instrument and is affected by vibrations and impacts generated from the precision instrument. FIG. 4 shows the stress generated in the hexagon socket head cap bolt 12 due to vibration or impact generated from a precision device (not shown) attached to the upper part of the general-purpose dovetail sliding unit 1. Here, the lower unit 3 of the general-purpose dovetail sliding unit 1 is omitted for explanation. For the sake of explanation, the sliding unit 4 of the upper unit 2 is illustrated as being slid to the left in the figure. Vibrations and impacts generated when using precision instruments can be broken down into a vertical force P1, a horizontal force P2, and a force P3 in a direction perpendicular to FIG. Among these, the lower unit 3 receives a bending moment M with respect to the force P1 in the vertical direction. Of the left and right hexagon socket head bolts 12, the hexagon socket head bolt 12b attached to the upper unit fastening hole 7b receives the tensile force F2 and resists the bending moment M. Further, a shearing force S is generated in the left and right hexagon socket head cap bolts 12 by the force P2 in the left-right direction and the force P3 in the direction orthogonal to FIG.

  As shown in FIG. 3, the hexagon socket head bolt 12 b resists the tensile force F <b> 2 generated in the lower unit 3 at the bearing surface with the bottom surface 18, and a tension T is generated. At this time, a viscoelastic material 20 is attached to the bottom surface 18 and is compressed and deformed by the tension T. Accordingly, the hexagon socket head cap bolt 12b is displaced in the vertical direction by this amount of compressive deformation. Due to this deviation, shear deformation occurs in the viscoelastic material 10 provided around the head 15 of the hexagon socket head bolt 12b, and energy is absorbed.

  On the other hand, the hexagon socket head cap bolt 12b tends to move in the left-right direction against the force P2 in the left-right direction and the shearing force S generated by the force P3 in the direction orthogonal to FIG. At this time, the viscoelastic material 10 is affixed to the side surface of the cylindrical portion 17 and is compressed and deformed by the movement of the hexagon socket head bolt 12b. Accordingly, the hexagon socket head bolt 12b is displaced in the left-right direction by this amount of compressive deformation. Due to this deviation, shear deformation occurs in the viscoelastic material 20 provided at the bottom 15 of the hexagon socket head cap bolt 12b, and energy is absorbed.

  Due to these viscoelastic materials 10 and 20, vibrations and impacts generated when using precision instruments are instantly absorbed and attenuated, and are hardly transmitted to the connecting component 6. Further, since the lower unit fastening hole 8 for connecting the connecting component 6 and the lower unit 3 has a similar mechanism, vibrations and impact forces generated when using precision instruments are further attenuated to lower the lower unit 3. Is transmitted to. That is, these energy absorption mechanisms are a kind of damping structure that controls vibration. In addition, these energy absorbing mechanisms absorb energy when a lower base (not shown) in which the general-purpose dovetail sliding unit 1 is installed generates vibrations or shocks due to earthquake motion or the like.

  In the dovetail sliding unit 100 constituting the conventional multi-function dovetail sliding unit 200, a hexagon socket is used in order to prevent the screws of the hexagon socket head cap screw 12 from being loosened or pulled out due to vibrations or impacts generated from the precision equipment to be mounted. An adhesive was injected when attaching the attached bolt 12 to fix the hexagon socket head bolt 12. However, in the general-purpose dovetail sliding unit 1 according to the present invention, the connecting component 6 is provided, and the connecting function is integrated into the connecting component 6. Furthermore, viscoelastic materials 10 and 20 are provided in the respective fastening holes 7 and 8 in the connecting part 6 to absorb and attenuate energy of vibrations and impacts generated from precision instruments. Therefore, the force due to vibration or impact applied to the hexagon socket head cap bolt 12 is greatly relieved, and the possibility of loosening or coming off of the screw is reduced.

  As described above, the general-purpose dovetail sliding unit 1 can be provided by providing the viscoelastic materials 10 and 20 instead of fixing the hexagon socket head cap bolt 12 with the conventional adhesive. That is, the viscoelastic materials 10 and 20 are fixed to the connecting part 6 but are not fixed to the hexagon socket head cap bolt 12. Therefore, the hexagon socket head cap screw 12 is detachable and can be freely assembled and disassembled by the user. Moreover, since the function about joining of the upper unit 2 and the lower unit 3 is concentrated on the connection part 6, the upper unit 2 and the lower unit 3 do not impair the function as a single unit. Furthermore, the adhesive used for the conventional multi-function dovetail sliding unit 200 had to be repaired by cutting off the adhesive due to impact when the bonding function deteriorated due to aging. However, in the general-purpose dovetail sliding unit 1 according to the present invention, the connecting component 6 can be easily replaced even when the joining function is deteriorated due to aging.

  In FIG. 5, other embodiment of the connection component 6 of the general purpose dovetail sliding unit 1 is shown. FIG. 5A is a plan view of the connecting component 16, FIG. 5B is an AA cross-sectional view thereof, and FIG. 5C is a BB cross-sectional view thereof. In the present embodiment, two connecting parts 16 a and 16 b having substantially the same size are overlapped with each other and the viscoelastic material 30 is provided in the gap between the connecting parts 16. In the present embodiment, the viscoelastic material 30 is affixed to the entire surface of the connecting parts 16 a and 16 b, but may be provided only around the hexagon socket head bolt 12. In this embodiment, the viscoelastic material 30 is bonded to both the connecting parts 16a and 16b. However, the viscoelastic material 30 may be bonded to only one of the connecting parts 16a and 16b, or may not be bonded to any of the connecting parts 16a and 16b. The position may be held by a frictional force with the connecting component 6.

  This viscoelastic material 30 shears and absorbs energy with respect to the shearing force S generated by the left-right force P2 and the force P3 orthogonal to FIG. 4, and attenuates vibration and impact. Further, separately from the viscoelastic material 30, the viscoelastic material 10 may be fixed to the inner surface of the cylindrical portion 17 of the fastening holes 7 and 8. In this case, the viscoelastic material 10 resists the bending moment M as described above.

  In this embodiment, the connecting component 16 is divided into two connecting components 16a and 16b. In this case, the diameter of the fastening holes 7 and 8 for the hexagon socket head cap bolt 12 provided on one side of the connecting component 16 is for the head 15 of the hexagon socket head cap bolt 12, and the hexagon socket head cap provided on the other side of the connecting component 16 is used. The diameter of the fastening holes 7 and 8 for the bolt 12 can be used for the threaded portion 19 of the hexagon socket head bolt 12. Or the reverse may be sufficient. Thereby, the process of the connection component 16 becomes only a normal simple drilling process, and a process is simplified.

  Further, the energy absorbing mechanism by the viscoelastic material 30 is used even when vibrations or shocks due to earthquake motion or the like occur on the lower base (not shown) where the general-purpose dovetail sliding unit 1 is installed. Absorb energy. That is, this energy absorption mechanism can take a larger shear surface in the viscoelastic material 30 and is therefore effective as a seismic isolation structure that does not transmit vibration from the base to the upper mechanism.

  In FIG. 6, other embodiment of the connection component of the general purpose dovetail sliding unit 1 is shown. 6A is a partial plan view of the connecting component 26, FIG. 6B is a cross-sectional view thereof taken along the line AA, and FIG. 6C is a plan view of the fastening member 22. FIG. In the present embodiment, the fastening holes 7 and 8 provided in the connecting component 26 are U-shaped fastening holes 21 in which the edge plate surface of the fastening member 26 is cut into a U-shape. The bottom surface 18 which is a bearing surface under the U-shaped fastening hole 21 is also U-shaped. The hexagon socket head cap bolt 12 can be attached along the bottom surface 18 at any position on the left and right in the figure. Therefore, even if the pitch of the bolt holes of the lower unit 3 is different, it can be adjusted and attached.

  When the viscoelastic body 40 is attached to the U-shaped fastening hole 21, the U-shaped fastening hole 21 is attached to the U-shaped portion and the bottom surface 18. Then, after the hexagon socket head bolt 12 is inserted, the tightening member 22 is inserted from the opening side of the U-shaped fastening hole 21. Further, the fastening member 22 is fastened to the connecting part 26 by the fastening bolt 23. A tightening bolt hole 24 for the tightening bolt 23 is formed in the connecting part 26. Thereby, the head 15 of the hexagon socket head cap bolt 12 is fastened by the viscoelastic material 40 from both sides, and a compressive force is generated in the viscoelastic material 40.

  FIG. 7 shows an embodiment of the general-purpose dovetail sliding unit 1 using the U-shaped fastening hole 21. FIG. 7A is a plan view of the general-purpose dovetail groove sliding unit 1, FIG. 7B is a sectional view taken along the line AA, and FIG. 7C is a sectional view taken along the line BB. is there.

A U-shaped fastening hole 21 is provided in the connecting component 26, and the hexagon socket head cap bolt 12 is inserted to be connected to the upper unit 2 of the dovetail sliding unit 100. The above-described tightening member 22 is inserted into the hexagon socket head bolt 12 inserted into the U-shaped fastening hole 21. Although not shown in the drawings, the connecting parts 26 are provided with viscoelastic materials 40 as shown in FIG.

As described above, the general-purpose dovetail sliding unit 1 can be combined with the single dovetail sliding unit 100 using the connecting component 36. Further, for example, by disassembling the connecting part 36, the dovetail sliding unit 100 can be attached to the back surface thereof. Furthermore, it is also possible to connect another dovetail sliding unit 100 that slides in an orthogonal direction to the dovetail sliding unit 100 via the connecting component 6. Although not shown, the connecting parts 36 are also provided with viscoelastic materials 10 and 20 as shown in FIG.

FIG. 9A is a side view of the general-purpose dovetail sliding unit 1, and FIG. 9B is an AA side view thereof. This general-purpose dovetail slide unit 1 is obtained by attaching a dovetail slide unit 100 to a mounting portion 32 of a known rotary handle 31 via a connecting part 46.
