Description

Hand tool with turnable grip

The present invention relates to hand tools, and in particular to a hand tool with a turnable handle.

Generally, hand tools are mostly used in fixed directions, such as straight screwdrivers or turning screwdrivers with specific angles such as 90-degree bends. In addition, this kind of fixed-angle hand tool can only be used in a certain direction. If it is used in situations where steering is required or space is limited, the type of hand tool used must be changed, causing inconvenience in use.

Furthermore, there are hand tools with turnable grips currently on the market. The grips are provided with two handles that can rotate relative to each other, and the two handles are driven to rotate at an angle by pushing the push button. However, when using such a hand tool with a turnable grip, users often accidentally touch or push the push button during the holding operation, causing the grip to turn unexpectedly, resulting in instability in use. causing safety concerns.

In view of this, the inventor of the present invention has devoted himself to research on the above-mentioned existing technology and cooperated with the application of academic theory to try his best to solve the above-mentioned problems, which has become the goal of improvement by the inventor of the present invention.

One object of the present invention is to provide a hand tool with a turnable handle, which prevents the user from touching the first and second handle turns during the holding operation, thereby improving stability and safety in use.

In order to achieve the above object, the present invention is a hand tool with a turnable handle, which includes a first handle, a second handle, a rotary latch group, a locking group and a spring. The first handle includes a first body and a first groove, and the first body has a first beveled surface at one end. The second handle is movably coupled to the first handle. The second handle includes a second body and a second groove. The second body has a second beveled surface at one end corresponding to the first beveled surface. The rotary latch group includes a rotating block and a latch block. The rotary block is disposed in the first groove, and the latch block is disposed in the second accommodating groove. The locking group includes a stud and a nut. The stud is passed through the locking block and the rotating block. One end of the stud is fixed in the first groove, and the other end is locked with a nut and is inserted in the second groove. The spring is placed outside the stud and elastically contacts the rotating block; wherein, the locking block and the rotating block can lock each other when the spring is compressed, and can be separated from each other when the spring is stretched. The first handle or the second handle The rotating block is driven away from the blocking block under external force. The first handle and the rotating block rotate relative to the second handle with the stud as the rotation center, and after rotating at a certain angle, the rotating block and the blocking block are locked with each other. , thereby positioning the first handle and the second handle.

Compared with the conventional ones, the hand tool with a turnable handle of the present invention is provided with beveled surfaces on the first and second handles respectively, and the rotary latch group is arranged between the first and second handles. , in addition, the stud is passed through the rotary catch group, and the spring is set outside the stud and elastically contacts the rotary catch group. Accordingly, the external force pulls the rotary catch group to lock each other, thereby positioning the first handle and The second handle eliminates the need for a traditional push button to allow the handle to rotate at an angle, thereby preventing the user from accidentally touching or pushing the push button during the holding operation and causing the handle to turn, thereby increasing stability and safety during use.
