Description

Multifunctional torque wrench

Technical Field

The present invention relates to a torque wrench, and more particularly to a portable multifunctional torque wrench.

Background

As shown in fig. 1, a conventional torque wrench 1 for bicycle maintenance comprises a handle 2 and a hexagonal wrench 3, wherein the hexagonal wrench 3 is disposed at one end of the handle 2 to form the torque wrench 1 in a T-shape, and a socket head 4 is disposed at the other end of the hexagonal wrench 3 to enable the socket head 4 to drive a socket such as a screw or a screwdriver head (not shown) by turning the handle 2 to turn the hexagonal wrench 3. The torque wrench 1 further comprises a needle bar 5 and a dial 6, when the hexagonal wrench 3 is twisted by a user pulling the handle 2, the needle bar 5 is displaced relative to the dial 6 to point to the corresponding scale on the dial 6, so as to obtain the torque value applied to the fastener by the socket 4. Because the bicycle frame (especially the carbon fiber frame) with high unit price has the torque limitation of the safe screw lock, the effect of protecting the carbon fiber frame of the bicycle can be achieved by utilizing the existing torque wrench 1, and the bicycle frame with high unit price is prevented from being cracked due to overhigh torque of the screw lock.

Although the conventional torque wrench 1 can display the torque value of the locking screw of the bicycle by the needle bar 5 corresponding to the scale on the dial 6, the conventional torque wrench 1 is limited in its structural design and thus provides only a single function as described above to the consumers. Since there is no additional function, for the general consumers of the bicycle, the conventional torque wrench 1 is not favored, and how to provide a multifunctional torque wrench is widely favored by the consumers of the bicycle, which is the key point to be solved by the present invention.

The multi-functional torque wrench as claimed in claim 6, wherein the shaft has a protruding section protruding in a radial direction and a recessed evasion section corresponding to the protruding section, the body has a pivot hole at the coupling portion for the shaft to pass through, and has a plurality of concave limit grooves corresponding to the protruding section, the limit grooves are used for the protruding section to be clamped and positioned when the body and the wrenching member are at the first position and the second position, respectively, and when the shaft slides in the axial direction, the evasion section faces the limit grooves to separate the clamping of the body and the wrenching member, so that the body can swing into or out of the receiving groove corresponding to the wrenching member.

8. The multi-function torque wrench as claimed in claim 7, wherein the body is a hexagonal rod, the engaging portion is formed by bending the body at one end thereof and forming the pivot hole, and the plurality of limiting grooves are formed at the engaging portion inside the pivot hole.

9. The multi-function torque wrench as claimed in claim 7, wherein the shaft is formed by joining a first shaft section and a second shaft section, one of the first shaft section and the second shaft section has a concave portion at one end and the other has a convex portion at one end, the concave portion and the convex portion are shaped and arranged in a concavo-convex manner, and the first shaft section and the second shaft section are joined by the concave portion and the convex portion in a concavo-convex manner.

10. The multi-function torque wrench as claimed in claim 9, wherein the wrench member has a first collar and a second collar disposed at opposite sides of the receiving slot, the first collar and the second collar are disposed through two ends of the shaft in the receiving slot, the shaft has a radially protruding stop portion at the first shaft section in the first collar, and the restoring elastic member is supported by two ends of the first collar against the stop portion and the wrench member.

11. The multi-functional torque wrench as claimed in claim 1, wherein the indicating device has an external member, the body has an adjusting seat rotatably disposed on the external member and adjacent to the engaging portion, one end of the indicating needle is pivotally connected to the adjusting seat, the adjusting seat is capable of being rotated and then positioned relative to the body, and the indicating end is adjusted at the position indicated by the indicating portion.

12. The multi-function torque wrench as claimed in claim 11, wherein the wrench member has a receiving slot, and the indicator is supported by a resilient piece in the receiving slot to press the indicating end against the indicating portion.

13. The multi-functional torque wrench of claim 12, wherein one end of the resilient plate is connected to the indicator and tilted out, and the other end of the resilient plate abuts against the extending portion to prop the indicator.

14. The multi-functional torque wrench of claim 12, wherein one end of the resilient plate is connected to the extension portion and tilted out, and the other end of the resilient plate abuts against the indicator and supports the indicator.
