Description

Hand tool with reversing function

The present invention relates to a hand tool, and particularly relates to a hand tool that can switch working directions and has a reversing function.

There are many hand tool sets on the market for users to choose from, such as screwdriver sets or socket sets. Such hand tool sets usually include a tool body and a plurality of tool heads of different specifications. Take the screwdriver set as an example, the tool body Contains a holding part and a set part, the holding part is used for the user to hold, the set part is used to install the tool bit, so that the user can choose the suitable tool bit to install according to the type and size of the workpiece To the fitting part, this type of hand tool set has the advantages of low cost and high versatility. However, for the tool body of this type of tool set, the gripping part and the sleeve part are usually fixed to each other and cannot be relatively pivoted, or the relative pivoting angle is too large or the available angles are relatively sparse, which is not conducive to the narrow space. Place to use.

In addition, in order to improve work efficiency, hand tools with a ratchet mechanism are provided on the market. The ratchet mechanism is a one-way intermittent rotation mechanism composed of a ratchet wheel and a pawl. When the hand tool rotates in a first direction, the pawl is inserted into the ratchet wheel. The two teeth drive the ratchet to rotate. When the hand tool rotates in a second direction opposite to the first direction, the pawl slides over the teeth of the ratchet without driving the ratchet, thereby making the ratchet One-way intermittent rotation. However, the pawl and the teeth of the ratchet wheel are only in open single-sided contact, and therefore, they often jump or collapse, resulting in insufficient torque. Therefore, there is still a need for hand tools equipped with other unidirectional intermittent rotation mechanisms on the market.

The purpose of the present invention is to provide a hand tool to solve the above-mentioned problems.

According to one embodiment of the present invention, a hand tool with a reversing function is provided, which includes a holding part, a connecting part and a sleeve part. The connecting part includes a connecting seat, a control part and a positioning gear. The connecting seat is connected with the holding part, and the connecting seat is formed with an opening. The control member includes a control body, a first elastic arm and a gear meshing part. The control body is clamped to the opening. The first elastic arm is connected to the control body and is adjacent to a hole wall of the opening. The first elastic arm includes A convex part, which is used to abut against the hole wall of the opening. The gear meshing part is connected with the first elastic arm and is bent relative to the first elastic arm. The positioning gear is pivotally connected to the connecting seat, and the positioning gear is configured to mesh with the gear meshing part. The sleeve part includes a pivot seat, which is pivotally connected to the connecting seat and connected with the positioning gear in the same motion. When the control member is not pushed by an external force, the first elastic arm drive gear meshing part meshes with the positioning gear. When the control member is pushed by an external force, the convex part abuts against the hole wall of the opening to displace the first elastic arm , Thereby driving the gear meshing part to disengage from the positioning gear.

According to another embodiment of the present invention, a hand tool with a reversing function is provided, which includes a steering switch sleeve. The steering switching sleeve includes a rotating drum, an accommodating drum, a sleeve tube, a first meshing part, an elastic member, a movable gear and an annular fixed piece. The accommodating cylinder is arranged in the rotating cylinder, and the accommodating cylinder includes a first limiting part. One end of the sleeve is arranged in the accommodating cylinder. The first engaging portion surrounds the sleeve. The elastic piece is arranged in the accommodating cylinder. The movable gear is movably arranged in the accommodating cylinder and abuts against the elastic member. The movable gear includes a second meshing portion and a movable flange. The second meshing portion is configured to mesh with the first The movable flange includes a movable top and a first movable flange surface, and the first movable flange surface is connected with the movable top. The annular fixing piece is fixedly arranged in the accommodating cylinder. The annular fixing piece includes a fixing flange. The fixing flange includes a fixing top and a first fixing flange surface. The first fixing flange surface is connected with the fixing top. When the movable gear is located at a first position relative to the accommodating cylinder, the fixed top and the movable top abut, the movable gear is pressed against the elastic member so that the elastic member accumulates an elastic force, and the second meshing part is separated from the first meshing part. When the movable gear is located at a second position relative to the accommodating cylinder, the movable gear abuts against the first limiting portion, and the elastic member releases the elastic force to push against the movable gear, so that the first movable flange surface and the first fixed flange surface abut against , And the second engaging portion is engaged with the first engaging portion.

The hand tool of the present invention can control the meshing state of the gear meshing part and the positioning gear by changing the force state of the control member, and adjust the relative angle of the whole set of the joint part and the grip part, thereby adjusting the work of the hand tool The direction, in addition, the angle that can be selected for this type of engagement is relatively fine, which is conducive to use in places with small spaces.

The hand tool of the present invention can control the meshing state of the first meshing part and the second meshing part by adjusting the position of the movable gear relative to the accommodating cylinder, which is beneficial to give the hand tool the function of unidirectional intermittent rotation, and can avoid The phenomenon of tripping and tooth collapse can provide relatively large torque.
