Description

Technical Field

[0001] This utility model belongs to the field of mechanical tools, and specifically relates to a vector bidirectional socket wrench. Background Technology

[0002] Currently, the main tools for tightening and loosening bolts are adjustable wrenches or socket wrenches. Adjustable wrenches are limited by the working space, and cannot be used in small, confined spaces. Socket wrenches, on the other hand, can only be used for one type of bolt, and different bolts require multiple sockets. The equipment is also bulky, increasing storage space and making it inconvenient to carry. Furthermore, each bolt needs to be compared one by one, which seriously affects work efficiency. Summary of the Invention

[0003] The technical problem this invention aims to solve is to provide a vector bidirectional socket wrench. This invention allows for easy adaptation to different sizes of bolts or nuts simply by turning the handle, eliminating the need for frequent socket changes and reducing operating costs. Furthermore, it allows for the selection of clamping blocks of various shapes, expanding its application scenarios and meeting diverse work needs.

[0013] Preferably, the circular through hole corresponds to the position of the hexagonal frame enclosed by the six clamping blocks.

[0014] Preferably, the outer edge of the control ring has a positioning groove, which corresponds to the position of the positioning hole, and the positioning groove is fixed in position by a positioning pin.

[0015] Preferably, the control ring has an internal hexagonal hole in the middle for detachable connection with the handle;

[0016] The handle features a ratchet design, with the rotation direction of the ratchet switched via a toggle knob mounted on the top of the handle. The end of the handle is a grip with an anti-slip outer sheath.

[0017] Preferably, the fastening block and the fastening pin are rotatably connected, with the fastening pin installed at the fastening hole, and the fastening pin and the fastening block cooperate to fasten the control ring.

[0018] The present invention can achieve the following beneficial effects:

[0019] This utility model adopts a split design, with the base and handle separate, making it convenient to carry and store, and flexibly adaptable to operations in confined spaces. The control ring, clamping block, and base work together, with the control ring's guide groove guiding the movement of the clamping block, which always maintains a hexagonal shape to tightly fit hexagonal bolts or nuts, ensuring a secure fastening effect.

Detailed Implementation

[0034] Preferred solutions include Figures 1 to 10 As shown, a vector bidirectional socket wrench includes a base 1, a control ring 2, a handle 3, a circular through hole 4, a torque cylinder 5, a side wall 6, a positioning hole 7, a fastening hole 8, a clamping block 9, a circular hole 10, a cylinder 11, an internal hexagonal hole 12, a guide groove 13, a positioning groove 14, a hexagonal column 15, a switching knob 16, a handle 17, a fastening block 18, and a fastening pin 19. When the circular through hole 4 of the vector bidirectional socket wrench is aligned with the target hexagonal bolt, and the handle is turned, the clamping block inside the vector bidirectional socket wrench will tightly nest around the head of the hexagonal bolt. The fastening pin 19 may have external threads. Rotating the fastening pin 19 can adjust the position of the fastening block 18, thereby locking the control ring. Turning the handle again will tighten or loosen the bolt.

[0035] The main components of this utility model are a base 1, a control ring 2, and a handle 3, and their structure and function are as follows:

[0036] 1. Control ring 2. The control ring 2 is circular in design. There is an internal hexagonal hole 12 in the center of the control ring 2. There is a positioning groove 14 on the outer edge of the control ring 2. The positioning groove 14 is mainly fixed in position by the positioning pin of the positioning hole 7 on the side wall of the base 1.

[0037] 2. Clamping block 9. Clamping block 9 is an irregular trapezoidal structure with a round hole 10 at one corner and a cylinder 11 at the other corner. The cylinder 11 is installed in the guide groove 13 of the control ring 2.

[0038] 3. Handle 3 is connected to the internal hexagonal hole 12 of the control ring 2 and is a detachable design. Handle 3 is a ratchet design, and the rotation direction of the ratchet is switched by the switching knob 16 installed on the upper part. The tail of handle 3 is a grip handle with an outer anti-slip design.

[0039] The base 1 is provided with 6 torque cylinders 5 for mounting 6 clamping blocks 9; there are 2 positioning holes 7 on the side wall of the base 1 through which positioning pins are inserted into the positioning grooves 14 of the control ring 2; there is 1 fastening hole 8 on the side wall of the base 1 through which the control ring 2 is fastened by fastening block 18.

[0040] The clamping block 9, driven by the control ring 2, can achieve regular movement while maintaining its hexagonal shape. The nested clamping block 9 is an irregular trapezoidal structure with a round hole 10 at one corner and a cylinder 11 at the other corner. The cylinder 11 is installed in the guide groove 13 of the control ring 2. The control ring 2 is circular, with an internal hexagonal hole 12 at its center and a positioning groove 14 along its outer edge. The positioning groove 14 is mainly fixed in position by the positioning pin in the positioning hole 7 on the side wall 6 of the base 1. A fastening hole 8 is also opened on the side wall of the base 1. The fastening pin 19 passes through the fastening hole 8 and connects to the fastening block 18. The fastening block 18 is mainly used to fasten the control ring 2 and prevent the clamping parts from loosening. Twisting the handle 3 can change the combined shape of the clamping block 9. The guide groove 13 of the control ring 2 can guide the movement trajectory of the clamping block 9 below. The direction and slope of the guide groove 13 can change the movement speed of the clamping block.

[0041] The control ring 2 is circular and nested inside the base 1. The control ring 2 guides the movement of the clamping block 9 through the guide groove 13.

[0042] The clamping block 9 is a rotating component that connects the base 1 and the control ring 2. By rotating the handle 3 at different angles, the workpiece can be correctly positioned.

[0043] Handle 3 is detachable and has a ratchet mechanism at the top.

[0044] The working principle of this device is as follows:

[0045] Align the hexagonal bolt head or hexagonal nut with the handle and turn it to adjust the size of the bolt or nut. Tighten or loosen the bolt or nut by locking the control ring.

[0046] This device adopts a split design, consisting of a base 1 and a handle 3. The base 1 contains a control ring 2, a clamping block 9, and a fastening pin 19. The handle is a ratchet design, which is suitable for working in limited spaces. Other shapes of clamping blocks can also be selected to adapt to different applications.
