DETAILED DESCRIPTION

[0025] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of an F-type wrench of the utility model in conjunction with the accompanying drawings.

[0026] For convenience, the direction along which the interference rod extends is called "axial", "axial direction" or similar terms, the direction perpendicular to the "axial" is called "radial" or similar terms, the direction in which the handwheel rotates clockwise is called "first direction" or similar terms, and the direction in which the handwheel rotates counterclockwise is called "second direction" or similar terms.

[0027] like Figure 1 As shown, a hand wheel 10 commonly used in industrial production includes a circular wheel disc 101, and a plurality of cross beams 102 extending from the center of the wheel disc 101 to the wheel disc 101. In this embodiment, the cross beams 102 are arranged in three pieces, and the three cross beams 102 are evenly arranged along the circumference of the wheel disc 101. In this arrangement, the three cross beams 102 can divide the wheel disc 101 into three equal parts. These structures of the hand wheel 10 are well known to those skilled in the art.

[0028] like Figure 2 As shown, an embodiment of the utility model provides an F-type wrench 100, comprising a disassembly mechanism 1 for rotating and disassembling a spiral fastener (not shown in the figure), and a clamping mechanism 2 connected to the disassembly mechanism 1 for clamping a hand wheel 10. In this way, the wrench 100 has the function of screwing the spiral fastener and the function of clamping the hand wheel 10 so that the hand wheel 10 cannot move.

[0029] In one embodiment, Figure 2As shown, the disassembly mechanism 1 includes a sleeve 11 for sleeved on the outer periphery of the spiral fastener, and a locking member 12 is arranged perpendicular to the axis of the sleeve 11. The sleeve 11 is arranged in any shape that is convenient for sleeved on the outer periphery of the spiral fastener. In this embodiment, the sleeve 11 is arranged in a circular ring structure. In this way, the annular space formed by the sleeve 11 can be used to accommodate the spiral fastener.

[0030] At the same time, the sleeve 11 is provided with a through hole (not shown in the figure) penetrating the sleeve wall, and the locking member 12 is arranged in the through hole and can move radially along the through hole. In this arrangement, the effective size of the annular space of the sleeve 11 can be adjusted by adjusting the radial position of the locking member 12 in the sleeve 11. In this way, the effective size of the locking member 12 in the sleeve 11 can be adjusted according to the different sizes of the force-bearing part of the spiral fastener. As a result, the disassembly mechanism 1 can be applied to spiral fasteners with different sizes of force-bearing parts, thereby increasing the applicability of the disassembly mechanism 1.

[0031] In one embodiment, the through hole is configured as a threaded hole, and the locking member 12 is configured as a threaded rod that matches the threaded hole. In this configuration, the locking member 12 can be screwed to adjust the effective size of the locking member 12 in the sleeve 11. When screwed into place, the threads that match the threaded hole and the threaded rod can engage with each other, so that the sleeve 11 and the locking member 12 cannot move relative to each other. In this way, the sleeve 11 can be stably sleeved on the outer periphery of the spiral fastener and connected to the spiral fastener.

[0032] According to a preferred embodiment of the present invention, Figure 2 As shown, the disassembly mechanism 1 further includes a force application rod 13 disposed on the sleeve 11 and extending outward. In this embodiment, the force application rod 13 is disposed along an axis perpendicular to the sleeve 11. In this way, when the sleeve 11 is rotated, the force application rod 13 can be used as a power arm to provide a force fulcrum, thereby driving the sleeve 11 to move in a labor-saving manner.

[0033] In this arrangement, when in use, the sleeve 11 is sleeved on the outside of the spiral fastener, and the locking piece 12 on the sleeve 11 is adjusted so that the locking piece 12 abuts against the spiral fastener inside the sleeve 11, thereby forming a relatively fixed connection between the spiral fastener and the sleeve 11.

[0034] Then, the force application rod 13 is rotated. At this time, the force application rod 13 can drive the sleeve 11 to rotate, thereby driving the spiral fastener located in the sleeve 11 to rotate synchronously. In this way, the spiral fastener can be screwed in or out.

[0035] According to a preferred embodiment of the present invention, Figure 2 As shown, the inner wall of the sleeve 11 is configured as a polygonal structure that is convenient for limiting the position of the spiral fastener. In this embodiment, the inner wall of the sleeve 11 is configured as a hexagonal structure. In this way, when the sleeve 11 is sleeved on the spiral fastener, the inner wall of the sleeve 11 can form a surface contact with the spiral rod, thereby increasing the friction between the spiral fastener and the sleeve 11, and preventing the spiral fastener from moving in the sleeve 11. As a result, the sleeve 11 can be further stably sleeved on the spiral fastener.

[0036] According to a preferred embodiment of the present invention, Figure 2 As shown, a screwing portion 14 for applying a force to the locking member 12 is fixedly provided at the free end of the locking member 12. The screwing portion 14 is configured to be any structure that is convenient for holding. In this embodiment, the screwing portion 14 is configured to be a sheet-like structure.

[0037] In this arrangement, when it is necessary to adjust the effective size of the locking member 12 in the sleeve 11, the staff can hold the screwing portion 14 and rotate it. During this process, the screwing portion 14 can drive the locking member 12 to move radially. In this way, the effective size of the locking member 12 in the sleeve 11 can be adjusted in a labor-saving manner.

[0038] In this arrangement, when in use, the sleeve 11 is sleeved on the outer circumference of the spiral fastener, and the screwing portion 14 is rotated, and the screwing portion 14 can drive the locking member 12 on the sleeve 11 to move toward the inside of the sleeve 11 until the end of the locking member 12 and the spiral fastener abut against each other. Thus, the spiral fastener and the sleeve 11 are relatively fixed.

[0039] Then, the force-applying rod 13 on the sleeve 11 is rotated. At this time, the force-applying rod 13 can drive the sleeve 11 to move synchronously. In this process, the spiral fastener in the sleeve 11 will move with the sleeve 11, so that the spiral fastener can be screwed in or out.

[0040] In one embodiment, Figure 2 As shown, the locking mechanism 2 includes an interference rod 21, a first end of which is connected to the disassembly mechanism 1, and a second end of which is provided with a contact with the crossbeam 102 along a first direction.

[0041] The first engaging assembly 22 is further provided with a second engaging assembly 23 on the interference rod 21 , and the second engaging assembly 23 is used to abut against another crossbeam 102 along a second direction opposite to the first direction.

[0042] In this way, the first clamping assembly 22 and the second clamping assembly 23 can respectively abut against the hand wheel 10 in opposite directions, so that the hand wheel 10 can be limited in opposite directions by the first clamping assembly 22 and the second clamping assembly 23. In this arrangement, a relatively fixed structure can be formed between the hand wheel 10, the first clamping assembly 22, and the second clamping assembly 23. Therefore, when the interference rod 21 connected to the first clamping assembly 22 and the second clamping assembly 23 is fixed, the circumferential movement of the hand wheel 10 can be limited.

[0043] In this arrangement, when the hand wheel 10 needs to be engaged so that the hand wheel 10 cannot move, the first engaging assembly 21 and the second engaging assembly 23 are respectively abutted against the two cross beams 102. At the same time, the interference rod 21 is arranged on the device connected to the hand wheel 10 so that interference occurs between the interference rod 21 and the device. In this way, the circumferential movement of the hand wheel 10 can be restricted.

[0044] In one embodiment, Figure 2 As shown, the first engaging assembly 22 includes an abutment portion 221 disposed on the interference rod 21 and extending in a direction perpendicular to the axis of the interference rod 21. In this arrangement, the abutment portion 221 can be used to abut against the crossbeam 102, thereby limiting the position of the hand wheel 10.

[0045] According to a preferred embodiment of the present invention, Figure 2 As shown, the first engaging assembly 22 further includes a bending portion 222 disposed between the interference rod 21 and the abutting portion 221, and the bending portion 222 is used to connect the abutting portion 221 and the interference rod 21 into one body. In this embodiment, the bending portion 222 is disposed tilted upward. Thus, an angle "ɑ" can be formed between the abutting portion 221 and the bending portion 222.

[0046] In this arrangement, the wheel disc 101 can be arranged within the angle "ɑ". In this process, the crossbeam 102 on the wheel disc 101 will abut against the bending portion 222, so that the hand wheel 10 can be limited in the circumferential direction. In this way, the hand wheel 10 can be stably arranged on the first engaging assembly 22.

[0047] In one embodiment, Figure 2 As shown, the second engaging assembly 23 includes a connecting portion 231 disposed around the interference rod 21 and capable of moving along the axis of the interference rod 21 , and a clamping block 232 disposed on the connecting portion 231 and extending outward, wherein the clamping block 232 is used to abut against the crossbeam 102 .

[0048] Among them, Figure 3As shown, the block 232 includes a first connection block 2321 disposed on the connection portion 231 and extending outward, and a second connection block 2322 disposed at the free end of the first connection block 2321 and extending perpendicularly to the first connection block 2321. The first connection block 2321 and the second connection block 2322 together form an "L" shape. In this arrangement, the first connection block 2321 can be disposed on the wheel disc 101, and the second connection block 2322 and the crossbeam 102 abut against each other. Thus, the hand wheel 10 is limited.

[0049] In one embodiment, Figure 2 As shown, the second engaging assembly 23 further includes a fixing member 233 disposed on the connecting portion 231, and the fixing member 233 is used to selectively fix the connecting portion 231 to the interference rod 21. In this embodiment, a fixing hole (not shown in the figure) is disposed on the connecting portion 231, and the fixing member 233 is configured as a fixing rod that can move radially along the fixing hole.

[0050] According to a preferred embodiment of the utility model, the fixing hole and the fixing rod are respectively provided with matching threads. In this way, the fixing rod can move along the fixing hole to fix the connecting portion 231 on the interference rod 21 or to disengage the connecting portion 231 from the interference rod 21. Thus, the connecting portion 231, the clamping block 232 and the interference rod 21 can be relatively fixed together in a selective manner. In this setting mode, the position of the second clamping assembly 23 on the interference rod 21 can be adjusted according to the different outer diameters of the wheel 101.

[0051] In one embodiment, Figure 2 As shown, on the interference rod 21, the limiting platforms 24 are fixedly arranged on both sides of the second engaging assembly 23, and the limiting platforms 24 are arranged around the outer circumference of the interference rod 21. In this way, a movement range of the second engaging assembly 23 can be formed between the limiting platforms 24. Therefore, it can be used to prevent the second engaging assembly 23 from continuously moving along the axis of the interference rod 21, thereby preventing the second connecting member 23 from being separated from the interference rod 21.

[0052] According to a preferred embodiment of the present invention, Figure 2 As shown, the first end of the interference rod 21 extends outward to form a hollow connecting tube 211, and the force rod 13 is telescopically sleeved in the connecting tube 211. In this arrangement, the axial length of the force rod 13 can be extended, so that when the disassembly mechanism 1 is used to screw the spiral fastener, the force arm of the force can be increased, so that the screwing of the spiral fastener can be completed in a more labor-saving manner.

[0053] At the same time, under this arrangement, the axial length of the interference rod 21 can also be increased. In this way, when the engagement mechanism 2 is used to engage the hand wheel 10, the force rod 13 can interfere with the device connected to the hand wheel 10. Thus, the applicability of the wrench 100 is increased.

[0054] The operation of the F-type wrench 100 according to the present invention is as follows.

[0055] The connecting tube 211 connected to the interference rod 21 is sleeved on the force rod 13, so that the disassembly mechanism 1 and the engagement mechanism 2 are connected into an integrated structure.

[0056] When the spiral fastener needs to be screwed, the sleeve 11 is placed on the outer circumference of the spiral fastener, and the screwing portion 14 is rotated. At this time, the screwing portion 14 can drive the locking member 12 on the sleeve 11 to move toward the inside of the sleeve 11 until the end of the locking member 12 and the spiral fastener abut against each other. In this way, the spiral fastener can be stably set in the sleeve 11.

[0057] Then, the engaging mechanism 2 connected to the disassembly mechanism 1 is rotated. At this time, the engaging mechanism 2 can drive the sleeve 11 to move synchronously. In this process, the spiral fastener located in the sleeve 11 will rotate together with the sleeve 11, so that the spiral fastener is screwed in or out.

[0058] When it is necessary to engage the handwheel 10 so that it cannot move, the second engaging component 23 is adjusted to a position on the interference rod 21 according to the outer diameter of the wheel 101, so that the distance between the first engaging component 22 and the second engaging component 23 matches the outer diameter of the wheel 101, and the first engaging component 22 and the second engaging component 23 are respectively abutted against the handwheel 10.

[0059] In this process, the wheel disc 102 is located in the angle "ɑ" formed between the abutting portion 221 and the bending portion 222, and the bending portion 222 and the cross beam 102 of the hand wheel 10 are abutted against each other. At the same time, the first connecting block 2321 can be placed on the wheel disc 101, and the second connecting block 2322 and another cross beam 102 are abutted against each other, so that the hand wheel 10 is subjected to the forces in opposite directions applied by the first clamping assembly 22 and the second clamping assembly 23 respectively.

[0060] Then, the disassembly mechanism 1 extending along the interference rod 21 is arranged on a device connected to the hand wheel 10 so that interference occurs between the disassembly mechanism 1 and the device. Thus, the hand wheel 10 can be engaged so that the hand wheel 10 cannot move.

[0061] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
