Description

Ratchet wrench with adjustable drive head angle

The invention relates to the structure of a ratchet wrench, in particular to a ratchet wrench which can adjust the angle of the driving head and can be applied to various construction environments.

According to the ever-changing technology, the design of various appliances is becoming more and more sophisticated. For example, in the automotive industry or precision industry, the assembly relationship between components and components is becoming more and more complicated, which causes some components to be constrained after assembly. Due to the limitations of its structure, the gap or angle between the two is limited. While the conventional ratchet wrench can provide the function of quickly turning the workpiece, the conventional ratchet wrench structure is a parallel working object, which can only rotate between parallel angles, which may result in limited construction space or workpiece locking angle. In the workplace, the work of disassembling or locking the workpiece (bolt) cannot be completed smoothly.

In view of this, how to solve the above problem is the primary problem to be solved by the present invention. Therefore, the inventor of the present invention finally has the invention after continuous hard thinking and trial work.

The main object of the present invention is to provide a ratchet wrench capable of adjusting the angle of the driving head, which has the function of adjusting the angle of the driving head and being applicable to various construction environments.

For the foregoing purposes, the present invention provides a ratchet wrench that can adjust the angle of the drive head, including:
a body having a head end and a cavity at the head end;
a ratchet wheel is disposed in the pocket and has a connecting portion at a center position of the ratchet;
a driving head having a driving end for driving the workpiece, and the driving head is formed at one end of the driving end to form a connecting end corresponding to the connecting portion, and the driving head is pivoted by the connecting end thereof At the connection portion of the ratchet, the driving head can perform a yaw operation with respect to the ratchet.

Wherein, the connecting portion has a polygonal slot, and the connecting end of the driving head has a polygonal shape matching the shape of the connecting portion, and the driving end has a polygonal column shape for the socket tool.

The driving head is provided with an axial through hole and is provided for a control rod. The control rod has a slot on one side of the control rod, and a through hole is formed at a position of the driving end relative to the step slot. A steel ball is disposed in the hole, and the steel ball is partially pushed by the slot of the control rod and partially exposed outside the through hole of the driving end, and a pressing member is disposed at the top of the connecting end of the driving head, and the pressing member has one end thereof Abutting against the control rod, the other end is extended outwardly and exposed outside the ratchet wheel, and an elastic member is disposed in the axial through hole, and one end of the elastic member is elastically abutted on the control rod, so that the control rod is constantly maintained at The steel ball is pushed by the top of the class slot and partially exposed outside the through hole of the driving end.

Of course, the present invention may be different in some of the components, or the arrangement of the components, but the selected embodiments are described in detail in the present specification.

Please refer to FIGS. 1 to 2 , which are a ratchet wrench with an adjustable drive head angle, which is mainly composed of a body 11 , a ratchet 21 and a drive head 31 , wherein:

The body 11 has a head end 12 and a handle 13 extending in the opposite direction of the head end 12, and the head end 12 of the body 11 defines a receiving slot 121 communicating with the external space.

The ratchet 21 is received in the receiving slot 121 and covered by a blocking piece 24 to prevent the ratchet wheel 21 from coming out of the receiving slot 121. The outer peripheral surface of the ratchet wheel 21 is composed of a plurality of ratchet teeth and has a ratchet portion 22 A connecting portion 23 is formed at a center of the ratchet 21. In the embodiment, the connecting portion 23 is formed by a polygonal slot.

The driving head 31 has a driving end 32 for driving the workpiece, and a driving end 32 of the driving end 31 opposite to the driving end 32 is formed with a connecting end 33 corresponding to the connecting portion 23, and the driving head 31 is provided. The connecting end 33 is pivotally connected to the connecting portion 23 of the ratchet 21, so that the driving head 31 can perform a yaw motion with respect to the ratchet 21. In the embodiment, the driving end 32 is in the shape of a quadrangular prism for the socket sleeve or the screwdriver head (not shown), and the set of the connecting end 33 is matched with the shape of the connecting portion 23. Multi-angled ball.

In addition, an axial through hole 34 is disposed in the driving head 31 and is disposed through a control rod 41. The control rod 41 is recessed with a class slot 42 on a side of the shaft facing the driving end 32, and the driving head is disposed on the driving head A through hole 35 is defined in the position of the driving end 32 relative to the step groove 42. The through hole 35 accommodates a steel ball 36 which can be pushed by the class slot 42 of the control rod 41 to be partially exposed to the driving. A pressing member 43 is disposed on the top of the connecting end 33 of the driving head 32. The pressing member 43 abuts the control rod 41 at one end thereof, and the other end extends outwardly to expose the ratchet wheel. 21, and an elastic member 44 is disposed in the axial through hole 34, and one end of the elastic member 44 is elastically abutted on the control rod 41, so that the control rod 41 is constantly held by pushing the steel ball 36 with its class groove 42. A portion is exposed at a position outside the through hole 35 of the driving end 32.

In the actual use of the present invention, as shown in FIG. 3, the driving head 31 is pivotally disposed in the connecting portion 23 of the ratchet 21 by the driving end 31 to constitute a The 360-degree adjustable universal structure allows the driving head 31 to pivot relative to the ratchet 21 to adjust the angle of the driving head 31. When the user turns the body 11, the driving head 31 is assembled 33. Between the connecting portion 23 of the ratchet 21 and the polygonal structure of the ratchet 21, the interlocking state is formed, and the purpose of smoothly driving the workpiece can be completed.

Then, referring to FIG. 4, when the user presses the pressing member 43 downward, the elastic member 44 is synchronously compressed and the control rod 41 is driven to move downward. At this time, the class slot 42 of the control rod 41 is no longer Pushing the steel ball 36 so that the steel ball 36 can fall into the groove 42 and retract into the through hole 35, thereby forming a quick release structure for tools such as a sleeve or a screwdriver ( The driving end 32 of the driving head 31 can be installed or removed. When the user stops applying force to the pressing member 43, the control rod 41 is affected by the restoring force of the elastic member 44. Again, the lever 41 is displaced to the position where the steel ball 36 is pushed up by the class slot 42, and thereby a positioning of a tool such as a sleeve or a screwdriver head mounted on the driving end 32 of the driving head 31 is generated. efficacy.

The disclosure of the above-described embodiments is intended to be illustrative of the invention, and is not intended to limit the invention.

In view of the foregoing, the present invention has been made in considerable advancement and practicality, and it will be apparent to those skilled in the art that the present invention is capable of achieving the foregoing objectives and is in accordance with the provisions of the Patent Law. Therefore, the inventor of this case filed an application in accordance with the law.
