Description

Technical Field

[0001] This application relates to the field of hardware tools technology, and in particular to a clamp. Background Technology

[0002] In mechanical manufacturing, fixtures are needed for various applications such as mold making, fitting, inspection, repair, and assembly to facilitate operations. Among the many types of fixtures available on the market, one type includes a ruler, a movable chuck mounted on the ruler, and a fixed chuck. When in use, operating the movable chuck moves the two chucks closer together along the ruler, allowing them to clamp and secure objects of different sizes and types for easier processing. However, in some scenarios, fixtures are needed to lift or reverse the gripping of objects, requiring the movable chuck to be moved further apart along the ruler.

[0003] In existing technologies, to enable the same clamp to be used in multiple application scenarios, the fixed clamp is usually reversed and mounted on the other end of the ruler, thus giving the clamp two different working modes. Specifically, when the fixed clamp and the movable clamp face each other, the clamp can be used to hold an object; when the fixed clamp and the movable clamp face opposite directions, the clamp can be used to lift the object.

[0004] Therefore, it is necessary to improve the existing fixture to facilitate switching between the two modes of the fixture for different application scenarios. Utility Model Content

[0005] Therefore, it is necessary to provide a clamp that can solve the problem that existing clamps are not convenient for users to operate to lock the clamp onto or unlock it from the ruler.

[0006] According to one aspect of this application, a clamp is provided, including a ruler and a fixing clamp that can be passed through the ruler, the fixing clamp comprising:

[0007] A clamping body, which is inserted through the ruler rod;

[0008] A locking assembly is disposed on the clamping body and includes a locking member and an operating member movably connected to the locking member;

[0009] The locking member has a locked state and an unlocked state, and the operating member can move between a first position and a second position;

[0010] When the operating component is in the first position, the locking component is in a locked state, and the fixing clamp can be fixedly installed on the ruler rod; when the operating component is in the second position, the locking component is in an unlocked state, and the fixing clamp can be detached from the ruler rod.

[0011] In some preferred embodiments, the locking assembly further includes a first elastic element disposed on the locking member, the first elastic element automatically holding the locking member in a locked state.

[0012] In some preferred embodiments, the locking member includes a connector and a locking pin connected to the connector, the first elastic member is located between the connector and the clamping body, and the connector drives the locking pin to move.

[0013] In some preferred embodiments, the ruler has a first end and a second end disposed opposite to each other, and both the first end and the second end are provided with locking holes; when the fixing clamp is installed on the ruler in the forward direction, the locking pin is located in the locking hole of the first end; when the fixing clamp is installed on the ruler in the reverse direction, the locking pin is located in the locking hole of the second end.

[0014] In some preferred embodiments, the locking assembly further includes a second elastic element located between the operating member and the clamping body, the second elastic element automatically holding the operating member in a first position.

[0015] In some preferred embodiments, the operating member can also move between a first position and a third position, with the first position located between the second position and the third position; when the operating member is in the third position, the locking member is in an unlocked state, and the fixing clamp can be detached from the ruler.

[0016] In some preferred embodiments, the actuating element is slidably movable relative to the clamping body between the first position and the second position, and / or between the first position and the third position.

[0017] In some preferred embodiments, when the fixing clamp is mounted upright on the ruler rod, the operating direction of the operating member moving from the first position to the second position is the same as the disassembly direction of the fixing clamp being removed from the ruler rod; when the fixing clamp is mounted in reverse on the ruler rod, the operating direction of the operating member moving from the first position to the third position is the same as the disassembly direction of the fixing clamp being removed from the ruler rod.

[0018] In some preferred embodiments, the operating direction of the operating member is perpendicular to the disassembly direction of the fixing clamp.

[0019] In some preferred embodiments, the locking member has an inclined surface at one end near the operating member and / or the operating member has an inclined surface on the side near the locking member, and the locking member and the operating member are connected by the inclined surface.

[0020] The aforementioned clamp, by setting a locking component on the clamping body of the fixed clamp, allows the user to easily lock the fixed clamp onto or unlock it from the ruler rod, and then quickly disassemble the fixed clamp and reverse it to the other end of the ruler rod. This allows for easy switching between the two usage modes of the clamp to apply to different application scenarios. Attached Figure Description

[0042] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0043] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0044] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0045] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0046] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0047] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0048] This application provides a clamp 10, which includes a fixed chuck 200 for clamping and fixing an object or lifting the object, thereby enabling convenient switching between two usage modes of the clamp 10 to be applied to different application scenarios.

[0049] The structure of the clamp 10 in this application will be described below. The embodiments of this application are only used as examples and do not limit the technical scope of this application.

[0050] Example 1:

[0051] See Figure 1 , Figure 1 A schematic diagram of the clamp 10 in one embodiment of this application is shown. The clamp 10 provided in one embodiment of this application includes a ruler 100, a fixed clamp 200, and a movable clamp 300. Both the fixed clamp 200 and the movable clamp 300 are mounted on the ruler 100. The movable clamp 300 has a handle 301. When the user operates the handle 301, the ruler 100 can move the fixed clamp 200 relative to the movable clamp 300, thereby controlling the movable clamp 300 and the fixed clamp 200 to move closer or further apart, for clamping or lifting objects. Figure 2 As shown, the ruler 100 has a first end 100a and a second end 100b arranged opposite to each other. The fixed clamp 200 can be selectively fixedly installed at either the first end 100a or the second end 100b. Specifically, both the fixed clamp 200 and the movable clamp 300 have a clamping surface 201. When the fixed clamp 200 is installed at the first end 100a of the ruler 100, the clamping surface 201 of the fixed clamp 200 is opposite to the clamping surface 201 of the movable clamp 300. The user can operate the handle 301 of the movable clamp 300 to bring the two clamps closer to each other. When the fixed clamp 200 is installed in reverse at the second end 100b of the ruler 100 (i.e., the fixed clamp 200 is installed backwards), the clamping surface 201 of the fixed clamp 200 is opposite to the clamping surface 201 of the movable clamp 300. The user can operate the handle 301 of the movable clamp 300 to move the two clamps away from each other.

[0052] like Figure 1-10As shown, the fixed clamp 200 includes a clamping body 210 and a locking assembly disposed on the clamping body 210. The clamping body 210 passes through the ruler rod 100 and is fixedly mounted on the ruler rod 100 by the locking assembly. The locking assembly includes a locking member 220 and an operating member 230, with the operating member 230 movably connected to the locking member 220. The locking member 220 has a locked state and an unlocked state, and the operating member 230 can move between a first position and a second position. When the operating member 230 is in the first position, the locking member 220 is in the locked state, and the fixed clamp 200 can be fixedly mounted on the ruler rod 100; when the operating member 230 is in the second position, the locking member 220 is in the unlocked state, and the fixed clamp 200 can be detached from the ruler rod 100.

[0053] It should be noted that, as Figure 3 and Figure 4 As shown, the clamping body 210 has a mounting surface 202 perpendicular to the clamping surface 201. The operating member 230 can move between a first position and a second position along a direction parallel to the mounting surface 202 and parallel to the extension direction of the ruler 100 (X+ and X- directions shown in the figure). The direction of movement of the operating member 230 from the first position to the second position is the operating direction. In this embodiment, when the fixed clamp 200 is installed in the forward direction at the first end 100a of the ruler 100, the operating direction is the X- direction, and when the fixed clamp 200 is installed in the reverse direction at the second end 100b of the ruler 100, the operating direction is the X+ direction. The locking member 220 can move in a direction parallel to the clamping surface 201 (Y+ and Y- directions shown in the figure), thereby switching the locking member 220 between a locked state and an unlocked state. The direction of movement of the locking member 220 from the unlocked state to the locked state is the locking direction, and the direction of movement of the locking member 220 from the locked state to the unlocked state is the unlocking direction. In this embodiment, when the fixed clamp 200 is installed in the forward and reverse directions at the first end 100a and the second end 100b of the ruler 100, the locking direction is the Y+ direction and the unlocking direction is the Y- direction. The direction in which the fixing clamp 200 is removed from the ruler rod 100 is the removal direction, and the direction in which the fixing clamp 200 is installed and fixed on the ruler rod 100 is the insertion direction. In this embodiment, when the fixing clamp 200 is installed in the forward direction at the first end 100a of the ruler rod 100, the removal direction is the X- direction and the insertion direction is the X+ direction. When the fixing clamp 200 is installed in the reverse direction at the second end 100b of the ruler rod 100, the removal direction is the X+ direction and the insertion direction is the X- direction.

[0054] See Figure 3 , Figure 5 and Figure 6The clamping body 210 includes a clamping frame 211 and a cover plate 212. The cover plate 212 has a mounting surface 202. The clamping frame 211 has a mounting groove 2111 on one side perpendicular to the mounting surface 202. The cover plate 212 is connected to the clamping frame 211 and closes the mounting groove 2111. Figure 2 As shown, the clamping frame 211 has positioning holes 2112 at its four corners outside the mounting groove 2111. The cover plate 212 has multiple connecting posts 2121 on the side facing the mounting groove 2111, each corresponding to a positioning hole 2112. The connecting posts 2121 are inserted into the positioning holes 2112 with an interference fit, so that the cover plate 212 is fixedly connected to the clamping frame 211 and closes the mounting groove 2111. Of course, the connection method between the cover plate 212 and the clamping frame 211 is not limited to this. They can also be connected to each other by fasteners or by adhesive, etc., which is not limited here. In this embodiment, a portion of the locking member 220 is located within the mounting groove 2111, and another portion passes through the cover plate 212 and is exposed outside the mounting groove 2111. The side of the cover plate 212 facing away from the mounting groove 2111 forms a mounting surface 202. The operating member 230 is slidably attached to the mounting surface 202 and slidably connected to the portion of the locking member 220 exposed outside the mounting groove 2111, thereby allowing the operating member 230 to control the movement of the locking member 220 to unlock.

[0055] like Figure 5 As shown, the cover plate 212 is also provided with a guide groove 2123, which extends along the extension direction of the ruler 100 (i.e., the X+ and X- directions shown in the figure). The operating member 230 has a corresponding guide block 232 on the side facing the cover plate 212. The guide block 232 is slidably confined within the guide groove 2123, thereby enabling the operating member 230 to move along the X+ and X- directions and preventing the operating member 230 from deviating from its movement path during movement. More preferably, based on this, as... Figure 3 As shown, the end of the guide block 232 is provided with a buckle 2321. The buckle 2321 passes through the guide groove 2123 and abuts against the side of the cover plate 212 opposite to the operating member 230, so that the operating member 230 is connected to the cover plate 212 while moving, which can prevent the operating member 230 from falling off the cover plate 212.

[0056] The operating component 230 and the locking component 220 are two separate parts, movably connected, with the operating component 230 controlling the locking component 220 to unlock. Specifically, the clamping surface 201 of the fixed chuck 200 is fixedly disposed on the clamping body 210, and the locking component 220 and the operating component 230 are movably disposed on the clamping body 210, both of which can move relative to the clamping body 210.

[0057] Furthermore, such as Figure 5As shown, the locking assembly also includes a first elastic element 240, which is located between the locking member 220 and the clamping body 210. The first elastic element 240 automatically holds the locking member 220 in a locked state. The locking member 220 includes a connector 221 and a locking pin 222. The connector 221 is used to contact the operating member 230, and the locking pin 222 is used to lock or unlock the clamping body 210 and the ruler 100 together. The locking pin 222 is fixedly installed on the connector 221, so that when the operating member 230 acts on the connector 221, the connector 221 can drive the locking pin 222 to move. The connector 221 is elastically connected to the clamping body 210 through the first elastic element 240. The first elastic element 240 is used to provide an elastic force to keep the locking member 220 in a locked state, so that the locking member 220 can automatically return to the locked state after changing from the locked state to the unlocked state without manual reset. In some embodiments, the first elastic element 240 may also be disposed between the connector 221 and the locking pin 222, with the locking pin 222 and the connector 221 elastically connected via the first elastic element 240. Further, to enhance the rebound force of the operating member 230, the locking assembly also includes a second elastic element 250, located between the operating member 230 and the clamping body 210, which can further hold the operating member 230 in the first position.

[0058] The connector 221 includes a protrusion 2211, the body of which is located within the mounting groove 2111. A limiting hole 2122 is provided on the cover plate 212. The end of the protrusion 2211 near the operating member 230 can pass through the limiting hole 2122 to be positioned within the cover plate 212, thus allowing the end of the protrusion 2211 near the operating member 230 to protrude from the mounting groove 2111. The operating member 230 has a protrusion 231 corresponding to the protrusion 2211 on the side facing the cover plate 212. The protrusion 2211 and the protrusion 231 can interact, thereby allowing the operating member 230 to control the unlocking of the locking member 220. Figure 5 As shown, in this embodiment, there are two protruding pillars 2211, which are spaced apart; correspondingly, there are also two protrusions 231, which are spaced apart, so that the operating member 230 can maintain balance when moving and avoid tilting the connecting member 221. It is understood that the number of protruding pillars 2211 and protrusions 231 is not limited and can be any number, which is not limited here. The connecting member 221 also has through holes 2212 penetrating through opposite sides of the connecting member 221, and the ruler 100 passes through the through holes 2212; in this embodiment, two protruding pillars 2211 are arranged on both sides of the through holes 2212, and a crossbar is fixedly arranged between the two protruding pillars 2211.

[0059] Furthermore, such as Figure 5 , 7As shown in Figure 8, both the locking member 220 near the operating member 230 and the operating member 230 near the locking member 220 are provided with inclined surfaces, and the locking member 220 and the operating member 230 are connected by the inclined surfaces. Specifically, the protrusion 2211 of the locking member 220 near the operating member 230 has a first inclined surface 220a, and the protrusion 231 of the operating member 230 also has a second inclined surface 230a. When the second inclined surface 230a of the operating member 230 interacts with the first inclined surface 220a of the protrusion 2211, the horizontal sliding of the operating member 230 relative to the mounting surface 202 can be converted into the vertical movement of the locking member 220 relative to the mounting surface 202. In some embodiments, the first inclined surface 220a can be formed only at the end of the protrusion 2211 near the operating member 230, or the second inclined surface 230a can be formed on the side of the protrusion 231 near the connector 221, which can also realize the steering function between the operating member 230 and the locking member 220. Specifically, in this embodiment, the connector 221 has a first inclined surface 220a on the side near the clamping surface 201 of the fixed clamp 200 in the X+ and X- directions, and the operating member 230 has a second inclined surface 230a on the side near the first inclined surface 220a in the Y- direction. The second inclined surface 230a of the operating member 230 can push the first inclined surface 220a of the locking member 220 to move in the unlocking direction, thereby moving the locking member 220 to the unlocking position.

[0060] like Figure 6 As shown, the locking pin 222 is disposed on the wall of the through hole 2212 (i.e., on the crossbar of the connector 221), and the connector 221 can drive the locking pin 222 to move together; when the operating member 230 drives the protrusion 2211 to move, it also drives the locking pin 222 to move at the same time. Locking holes 101 are provided at both opposite ends of the ruler 100, and the locking holes 101 correspond to the locking pin 222. The fixed chuck 200 can be selectively fixedly installed with any locking hole 101, thereby realizing the forward and reverse installation of the fixed chuck 200.

[0061] Specifically, such as Figure 9 , 10As shown, the locking pin 222 can be inserted into the locking hole 101 to lock the clamping body 210 onto the ruler 100, and the locking member 220 is in a locked state; or the locking pin 222 can be disengaged from the locking hole 101 to unlock the clamping body 210 and the ruler 100. When the locking pin 222 is inserted into the locking hole 101 at the first end 100a of the ruler 100, the clamping surface 201 of the fixed clamp 200 can clamp the object together with the clamping surface 201 of the movable clamp 300; when the locking pin 222 is inserted into the locking hole 101 near the second end 100b of the ruler 100, the fixed clamp 200 is reversed on the ruler 100, and the clamping surface 201 of the fixed clamp 200 can lift the object together with the clamping surface 201 of the movable clamp 300. Thus, when the operating member 230 pushes the locking member 220 to move in the unlocking direction, the connecting member 221 can drive the locking pin 222 to move together, so that the locking pin 222 is located outside the locking hole 101 of the ruler 100; and when the locking member 220 as a whole needs to be reset to the locked position, the connecting member 221 can drive the locking pin 222 to move together, so that the locking pin 222 is re-inserted into the locking hole 101. At the same time, in order to facilitate the installation and fixation of the clamp 200 on the ruler 100, bevels (unlabeled) are provided on both sides of the locking pin 222 along its own radial direction. When the fixed chuck 200 and the movable chuck 300 are installed facing each other, the inclined surface on one side of the locking pin 222 presses against the ruler 100, compressing the first elastic element 240 until the locking pin 222 extends into the locking hole 101, at which point the first elastic element 240 rebounds. When the fixed chuck 200 and the movable chuck 300 are installed in opposite directions, the inclined surface on the other side of the locking pin 222 (not labeled) presses against the ruler 100, compressing the first elastic element 240 until the locking pin 222 extends into the locking hole 101, at which point the first elastic element 240 rebounds. It should be noted that when the locking pin 222 extends into the locking hole 101, the locking pin 222 abuts against the direct surface of the locking hole 101, thus preventing the locking pin 222 from disengaging from the locking hole 101 without the action of the operating element 230.

[0062] When the fixed chuck 200 and the movable chuck 300 are installed in the forward orientation:

[0063] First, align the clamping surface 201 of the fixed chuck 200 with the clamping surface 201 of the movable chuck 300, and insert the fixed chuck 200 into the ruler 100 along the insertion direction. Then, the locking pin 222 of the fixed chuck 200 abuts against the first end 100a of the ruler 100, the first elastic element 240 is compressed, and the locking pin 222 elastically abuts against the ruler 100. Finally, continue moving the fixed chuck 200 in the insertion direction until the locking pin 222 automatically falls into the locking hole 101 of the first end 100a of the ruler 100 under the action of the first elastic element 240, thereby quickly and conveniently completing the installation and fixing of the fixed chuck 200.

[0064] When the fixed chuck 200 and the movable chuck 300 are installed in reverse:

[0065] First, with the clamping surface 201 of the fixed chuck 200 facing away from the clamping surface 201 of the movable chuck 300, the fixed chuck 200 is inserted into the ruler 100 in the reverse direction. Then, the locking pin 222 of the fixed chuck 200 abuts against the second end 100b of the ruler 100, the first elastic element 240 is compressed, and the locking pin 222 elastically abuts against the ruler 100. Finally, the fixed chuck 200 is moved further in the insertion direction until the locking pin 222 automatically falls into the locking hole 101 of the second end 100b of the ruler 100 under the action of the first elastic element 240, thus quickly and conveniently completing the reverse installation and fixing of the fixed chuck 200.

[0066] When the fixed clamp 200 is unlocked from the ruler 100:

[0067] First, the operating member 230 is moved in the operating direction, and the second inclined surface 230a of the operating member 230 presses against the first inclined surface 220a of the locking member 220. Then, the first elastic member 240 is compressed, causing the locking member 220 to move in the unlocking direction until the locking pin 222 disengages from the locking hole 101 of the ruler 100. Finally, the fixed clamp 200 is slid in the disassembly direction. When the locking pin 222 elastically abuts against the ruler 100, the operating member 230 is released and the fixed clamp 200 is slid further until the fixed clamp 200 separates from the ruler 100, thus quickly and conveniently disassembling the fixed clamp 200.

[0068] Example 2:

[0069] like Figure 11-13 A schematic diagram of the clamp 10 in another embodiment of this application is shown. The clamp 10 in this embodiment differs from the clamp 10 in Embodiment 1 in that the operating direction of the operating member 230 of the fixing chuck 200 in this embodiment is different from the operating direction of the operating member 230 in Embodiment 1. The operating direction of the operating member 230 is perpendicular to the disassembly direction of the fixing chuck 200. Specifically, as shown... Figure 12 and Figure 13As shown, the operating member 230 can move between a first position and a second position along a direction parallel to the mounting surface 202 and perpendicular to the extension direction of the ruler 100 (the Z+ and Z- directions shown in the figure). The direction of movement of the operating member 230 from the first position to the second position is the operating direction (i.e., the Z+ direction shown in the figure). In this embodiment, the connecting member 221 has a first inclined surface 220a on the side of the fixed clamp 200 away from the clamping surface 201 in the Z direction, and the operating member 230 has a second inclined surface 230a on the side of the operating member 230 close to the first inclined surface 220a. The second inclined surface 230a of the operating member 230 can push the first inclined surface 220a of the locking member 220 to move towards the unlocking direction, thereby moving the locking member 220 to the unlocking position. In some embodiments, the connector 221 has a first inclined surface 220a on the side of the fixed clamp 200 near the clamping surface 201 in the Z direction, and the operating member 230 has a second inclined surface 230a on the side of the operating member 230 near the first inclined surface 220a; the second inclined surface 230a of the operating member 230 can push the first inclined surface 220a of the locking member 220 to move toward the unlocking direction, thereby moving the locking member 220 to the unlocking position.

[0070] It can be seen that, regardless of whether the fixed chuck 200 is installed upright or in reverse, the operating direction of the operating member 230 is always perpendicular to the disassembly direction of the fixed chuck 200. Compared to Embodiment 1, where the operating direction of the operating member 230 is opposite to the disassembly direction of the fixed chuck 200 when the fixed chuck 200 is installed in reverse, the change in the operating direction of the operating member 220 in this embodiment is more conducive to the quick and convenient disassembly of the fixed chuck 200.

[0071] Example 3:

[0072] like Figure 14-21 A schematic diagram of the fixture 10 in another embodiment of this application is shown. The difference between the fixture 10 in this embodiment and the fixture 10 in embodiment 1 is that the operating direction of the operating member 230 of the fixing chuck 200 in this embodiment is two and selectable. Specifically, as shown... Figure 15-17As shown, the operating member 230 can also move between a first position and a third position, with the first position located between the second and third positions. When the operating member 230 is in the third position, the locking member 220 is also in an unlocked state, and the fixing clamp 200 can be detached from the ruler 100. That is, the operating member 230 can move between the first and second positions, and between the first and third positions, along a direction parallel to the mounting surface 202 (X+ and X- directions shown in the figure). The direction of movement of the operating member 230 from the first position to the second position (X+ direction shown in the figure) is the operating direction, and the direction of movement of the operating member 230 from the first position to the third position (X- direction shown in the figure) is also the operating direction. In this embodiment, the connecting member 221 includes two protrusions 2211, which are spaced apart; the operating member 230 includes two protrusions 231, which are spaced apart. The two protrusions 2211 of the connector 221 are provided with two first inclined surfaces 220a on their sides in the X+ and X- directions, respectively. The two protrusions 231 of the operating member 230 are provided with second inclined surfaces 230a on their sides near the corresponding first inclined surfaces 220a. The second inclined surfaces 230a of the operating member 230 can push the first inclined surfaces 220a of the locking member 220 to move in the unlocking direction, thereby moving the locking member 220 to the unlocked position. Further, in this embodiment, in order to enhance the rebound force of the operating member 230 in both directions, the locking assembly also includes two second elastic members 250. Each second elastic member 250 is located between the operating member 230 and the clamping body 210. The two second elastic members 250 can further hold the operating member 230 in the first position.

[0073] With this setting, such as Figure 18-21 As shown, when the fixed chuck 200 and the movable chuck 300 are installed facing each other, the operating member 230 moves along the operating direction (i.e., the X-direction shown in the figure) to move from the first position to the second position, the locking member 220 unlocks, and at the same time pushes the fixed chuck 200 to move along the disassembly direction (i.e., the X-direction shown in the figure). At this time, the operating direction of the operating member 230 is the same as the disassembly direction of the fixed chuck 200. While using the operating member 230, the fixed chuck 200 can be pushed to move, thereby facilitating the disassembly of the fixed chuck 200. When the fixed chuck 200 and the movable chuck 300 are installed in opposite directions, the operating member 230 moves along the operating direction (i.e., the X+ direction shown in the figure) to move from the first position to the third position, the locking member 220 unlocks, and at the same time pushes the fixed chuck 200 to move along the disassembly direction (i.e., the X+ direction shown in the figure). At this time, the operating direction of the operating member 230 is the same as the disassembly direction of the fixed chuck 200. While using the operating member 230, the fixed chuck 200 can be pushed to move, thereby facilitating the disassembly of the fixed chuck 200.

[0074] It can be seen that, regardless of whether the fixed chuck 200 is installed forward or backward, since the operating direction of the operating component 230 is selectable, the operating direction of the operating component 230 can always be the same as the disassembly direction of the fixed chuck 200, which makes it easier to quickly and conveniently disassemble the fixed chuck 200.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
