Description

Technical Field

[0001] This invention relates to a tool, and more particularly to an innovative structural form of a lever-type tool for rotating and actuating screws or similar items. Prior Technology

[0002] A conventional lever tool is used to connect an operator and a target object, the target object being a screw or similar item, or a sleeve for engaging and actuating the rotation of a bolt or nut. The lever tool is disposed on the operator, and by operating the operator to rotate, the target object can be actuated to rotate via the lever tool.

[0003] The rod-type tool includes a main rod and a steel ball. The main rod forms a working rod segment and a connecting rod segment along the axial direction. A braking part is formed at the end of the working rod segment away from the connecting rod segment. The braking part is used to insert or otherwise detachably connect the object to the main rod, thereby causing the main rod to rotate the object. The radial outer periphery of the connecting rod segment is mainly composed of a first plane, a second plane, and four third planes connected obliquely. The first plane and the second plane are opposite to each other along the diameter direction of the connecting rod segment.

[0004] A portion of the steel ball is embedded in the connector segment, while the other portion of the steel ball protrudes from the connector segment through the first plane.

[0005] The plug-in rod section is used to insert the actuator, which provides the user with operation and improves the ease of controlling the main rod to rotate the controlled object.

[0006] The operator includes a grip portion forming a socket that extends from the interior of the grip portion to one end of the grip portion. The grip portion has six obliquely connected walls that surround the radial center of the socket, such that the radial shape of the socket matches the hexagonal shape of the plug-in rod segment.

[0007] When the rod-shaped tool is installed on the manipulator, the plug-in rod segment moves axially to insert into the plug hole. The first plane, the second plane and each of the third planes are respectively opposite to one of the hole walls in the radial direction of the main rod, and the steel ball abuts against one of the hole walls, while the second plane abuts against the other hole wall.

[0008] Hold and operate the operator to rotate. The gripping part pulls the main rod to rotate, thereby pulling the object to rotate through the pulling part. The resistance of the object acts on the main rod. Since the steel ball abuts against one of the hole walls to form a point contact, and the second plane abuts against the other hole wall to form a planar contact, the plug-in rod section can easily slide relative to the gripping part.

[0009] The lever-shaped tool can also be mounted on another type of manipulator, which has three jaws, each of which is spaced apart along the circumference of a virtual circular line. Each jaw can move closer to or away from the center of the circular line along the diameter of the circle.

[0010] When the rod-shaped tool is set in the other type of manipulator, the plug-in rod segment is placed between each of the jaws, and then the other type of manipulator is operated to move each of the jaws toward the plug-in rod segment, and each of the jaws chooses to abut against the second plane or any of the third planes, thereby clamping the rod-shaped tool.

[0011] The steel ball design ensures that when the connector segment enters between the grippers, the first plane must avoid being opposite to any of the grippers. Otherwise, the steel ball will abut against any of the grippers, causing the axis of the connector segment to deviate from the center of the circular line. The other two grippers will not be able to tightly abut against either of the third planes. When the other actuator rotates the main rod in subsequent operations, the connector segment will easily detach from the grippers. Summary of the Invention

[0012] The main objective of this invention is to provide a lever-type tool that aims to solve the technical problem of developing a new type of lever-type tool with more ideal practicality for rotating and braking screws or similar items.

[0013] Based on the aforementioned objectives, the main technical feature of this invention in solving the problem lies in the rod-shaped tool, which includes:

[0014] A main rod, comprising a working rod segment and a connecting rod segment along its axial direction, wherein the working rod segment forms a braking part, constituting one end of the main rod along its axial direction, the braking part being used to brake the rotation of a controlled object; the connecting rod segment constituting the other end of the main rod along its axial direction, the radial outer periphery of the connecting rod segment being primarily composed of six outer surfaces; and

[0015] A supporting element is provided on the plug-in rod segment, a portion of which is embedded in the plug-in rod segment, and the other portion of which protrudes from the plug-in rod segment through two selected adjacent outer surfaces.

[0016] The main effect and advantage of this invention is that when the plug-in rod segment is inserted into the socket of an operator, the supporting element abuts against two adjacent walls of the operator. The plug-in rod segment is located at a first corner between two adjacent outer surfaces, corresponding to a second corner of the operator formed by the oblique adjacency of the other two walls. When the operator is rotated, it is not easy for relative sliding to occur between the plug-in rod segment and the operator.

[0017] Another effect and advantage of the present invention is that when the plug-in rod segment is inserted into another manipulator with three grippers, each of the grippers can choose to abut against any one of the outer surfaces, thereby clamping the plug-in rod segment.

[0019] The figures illustrate embodiments of the rod-shaped tool of the present invention, but these embodiments are for illustrative purposes only and are not limited to this structure in the patent application.

[0020] As shown in Figures 1 and 2, the first embodiment of the rod-type tool includes a main rod 10 and a supporting element 20. The main rod 10 forms a working rod segment 11 and a plug-in rod segment 12 along the axial direction. The working rod segment 11 forms a braking part 13, which constitutes one end of the main rod 10 along the axial direction. The braking part 13 is used to brake the rotation of a controlled object (not shown in the figure). The plug-in rod segment 12 constitutes the other end of the main rod 10 along the axial direction. The radial outer periphery of the plug-in rod segment 12 is mainly composed of six outer surfaces 14.

[0021] The actuating part 13 is selected as a rod-shaped structure with a hexagonal radial cross section. Accordingly, when the object being processed is a sleeve that can be used to fit a nut or bolt head, the actuating part 13 can be inserted into the object being processed, thereby locking or removing the nut or bolt by rotating the object being processed. The actuating part 13 can also be replaced with a slotted or cross-shaped structure. When the object being processed is a screw with a slotted or cross-shaped groove on the head, the actuating part 13 is used to embed the head of the screw, thereby locking or removing the screw by rotating the object being processed. The actuating part 13 can also be replaced with other types of structures. Such structural replacements of the actuating part 13 are those that can be easily conceived by those skilled in the art based on ordinary knowledge.

[0022] The radial outer periphery of the plug-in rod segment 12 is mainly formed by the outer surfaces 14 arranged obliquely in sequence, with each outer surface 14 circumferentially surrounding the radial center of the plug-in rod segment 12.

[0023] The abutting element 20 is disposed on the plug-in rod segment 12, a portion of the abutting element 20 is embedded in the plug-in rod segment 12, and the other portion of the abutting element 20 protrudes from the plug-in rod segment 12 through two selected adjacent outer surfaces 14.

[0024] Specifically, the supporting element 20 is made of steel balls. In conjunction with the selection of the supporting element 20 as being made of steel balls, it is preferable that the outer diameter of the supporting element 20 is slightly smaller than the width of the outer surface 14.

[0025] As shown in Figures 3 to 5, Embodiment 1 can be used in a first type of operator 50, which includes a gripping part 51, wherein the gripping part 51 forms a socket 52, the socket 52 extends from the interior of the gripping part 51 to one end of the gripping part 51, and the gripping part 51 forms six wall surfaces 53 that are obliquely connected and surround the radial center of the socket 52, so that the radial shape of the socket 52 matches the plug-in rod segment 12.

[0026] To facilitate insertion of the plug segment 12 into the socket 52, the plug segment 12 and the socket 52 are typically dimensionally tolerant. When the plug segment 12 is inserted into the socket 52, the abutment element 20 abuts against two adjacent wall surfaces 53, thereby guiding the plug segment 12 to abut against two adjacent outer surfaces 14 opposite to its lateral side in the diametrical direction relative to the other end of the abutment element 20, such that the plug segment 12 is located at a first corner 15 between the outer surfaces 14. The gripping part 51 is formed by two adjacent walls 53 at an oblique angle to a second corner 54. When the operator 50 is rotated, the gripping part 51 pulls the object to rotate through the main rod 10. Since the abutting element 20 cooperates with the two adjacent outer surfaces 14 to abut the gripping part 51 at both ends of the diameter direction of the insertion rod section 12, when the resistance of the object is transmitted to the insertion rod section 12 and the abutting element 20, it is not easy for relative sliding to form between the insertion rod section 12 and the gripping part 51.

[0027] As shown in Figures 6 and 7, in Embodiment 1, a second type of manipulator 60 can be optionally installed. The manipulator 60 has three grippers 62, which are spaced apart and can move closer to or further away from the radial center of the manipulator 60.

[0028] In Embodiment 1, when the manipulator 60 is set, the plug-in rod segment 12 enters between each of the grippers 62. The manipulator 60 is operated so that each of the grippers 62 moves toward the plug-in rod segment 12, and each of the grippers 62 selects to abut against any one of the outer surfaces 14, thereby clamping the plug-in rod segment 12.

[0029] When each of the grippers 62 moves toward the radial center of the plug-in rod segment 12 and abuts against the plug-in rod segment 12, the spatial relative configuration of the abutting element 20 with respect to the plug-in rod segment 12 ensures that the abutting element 20 will not contact any of the grippers 62, the axis of the plug-in rod segment 12 will not deviate from the center between the grippers 62, and each of the grippers 62 can tightly abut against any of the outer surfaces 14, thereby effectively clamping and positioning the plug-in rod segment 12. When the operator 60 is operated to cause the main rod 10 to rotate, the plug-in rod segment 12 is not easily disengaged from the grippers 62.

[0030] Referring again to Figures 1 and 2, the plug-in rod segment 12 is configured to form a chamber 16, which extends radially outward from the plug-in rod segment 12. The plug-in rod segment 12 forms a bearing surface 17 located in the chamber 16. The supporting element 20 is disposed in the chamber 16, and a pushing element 30 is disposed in the chamber 16. The pushing element 30 elastically pushes against the supporting element 20 and the bearing surface 17. The pushing element 30 is configured using a spring.

[0031] In the first embodiment, when the manipulator 50 is installed, during the initial stage of the insertion rod segment 12 being axially inserted into the socket 52, the supporting element 20 can move inward toward the insertion rod segment 12 as appropriate. When the insertion rod segment 12 is further inserted into the socket 52, the pushing element 30 pulls the supporting element 20 to move and support the gripping part 51. The force exerted by the pushing element 30 on the supporting element 20 helps the supporting element 20 maintain its supporting effect on the gripping part 51. When the manipulator 50 is operated or moved to change the posture of the main rod 10 in space, the insertion rod segment 12 is not easy to slide out of the socket 52 in the opposite direction. The change in the posture of the main rod 10 in space includes, but is not limited to, the state in which the insertion rod segment 12 is higher than the working rod segment 11 in space.

[0032] The main rod 10 may optionally have a neck section 18 located between the working rod section 11 and the plug rod section 12, and the outer diameter of the neck section 18 is smaller than that of the working rod section 11 and the plug rod section 12.

[0033] Figures 8 to 10 show the state of the third type of operator 70 in Embodiment 1. The operator 70 forms a socket 72 and a mounting groove 75. The socket 72 extends to one end of the operator 70. The operator 70 forms six wall surfaces 73 that are obliquely connected and surround the radial center of the socket 72, so that the radial shape of the socket 72 matches the plug-in rod segment 12. The mounting groove 75 extends to one side of the wall surface 73 that communicates with the socket 72. A stop bead 76 is provided in the mounting groove 75. A part of the stop bead 76 enters the socket 52, and the other part of the stop bead 76 is located in the mounting groove 75 and is elastically resisted by an elastic element 77. Accordingly, the stop bead 76 can be completely retracted into the mounting groove 75.

[0034] In the first embodiment, when the plug-in rod segment 12 is inserted into the socket 72 along the axial direction, the abutment element 20 is positioned between two adjacent wall surfaces 73 in the radial direction of the socket 72. The abutment element 20 is misaligned with the stop bead 76 in the circumferential direction surrounding the radial center of the socket 72. Therefore, even if the operator fails to notice the abutment element 20 and the stop bead 76 while inserting the plug-in rod segment 12 into the socket 72, the abutment element 20 will not be misaligned with the stop bead 76. During the axial movement of the plug rod segment 12 along the socket 72, the abutment element 20 will not be blocked by the stop bead 76. Then, when the neck segment 18 and the stop bead 76 are radially opposite each other along the socket 72, the elastic element 77 causes the stop bead 76 to abut against the radial outer periphery of the neck segment 18. The stop bead 76 restricts the plug rod segment 12, making it difficult for the plug rod segment 12 to arbitrarily exit the socket 72.

[0035] As shown in Figures 11 and 12, the main difference between Embodiment 2 and Embodiment 1 is that the supporting element 20 is a structure formed by molding an elastic material, and the supporting element 20 is fixedly connected to the plug-in rod segment 12. Specific examples of the elastic material include, but are not limited to, rubber. Furthermore, Embodiment 2 does not form the chamber 16 of Embodiment 1, nor does it have the pushing element 30 of Embodiment 1.

[0036] When the second embodiment is installed on the operator 50, the abutment element 20 utilizes the elasticity of its material to elastically abut against the two adjacent wall surfaces 53.

[0037] In Embodiment 2, the chamber 16 may be further formed in the same manner as in Embodiment 1, and the pushing element 30 of Embodiment 1 may be selected. The configuration is not shown in the drawings, but is based on alternative embodiments that can be easily conceived from Embodiments 1 and 2.
