Abstract

A driving tool includes a housing, a follower assembly, a driving assembly, a pressing handle, and a toothed rod. The follower assembly is arranged at an end of the housing and includes a follower element. The follower element has an annular follower toothed portion and is rotatably disposed in the housing. The driving assembly includes a first driving element, a second driving element, and an one-way rotation structure. The first driving element and the second driving element have annular first driving toothed portion and second driving toothed portion respectively. The first driving element and the second driving element are rotatably disposed on the housing coaxially. The driving element is connected to the second driving element via the one-way rotation structure. When the first driving element rotates along a first direction, the first driving element drives the second driving element to rotate via the one-way rotation structure. When the first driving element rotates reversely, the one-way rotation structure prevents the second driving element from being rotated by the first driving element. The pressing handle includes a driving toothed element engaged with the first driving toothed portion so as to drive the first driving element to rotate along the first direction or reversely by the movement of the pressing handle. The toothed rod is arranged in the housing and has a first transmission toothed portion and a second transmission toothed portion at two ends. The first transmission toothed portion is engaged with the follower toothed portion so that the toothed rod is able to drive the follower element to rotate. The second transmission toothed portion is engaged with the second driving toothed portion so that the second driving element is able to drive the toothed rod to rotate.

Description

Drive tool

The invention relates to a driving tool.

Generally speaking, the two ends of the driving tool are connected to the workpiece to be driven and the user can pull the drive to rotate the workpiece to be driven, however, the traditional driving tool is extremely labor-intensive, and must be pulled up and reconnected after pulling The next time it is pulled, it cannot be driven continuously, which is extremely inconvenient.

In this regard, as described in the patent TW I627028, a continuously-driving driving tool appeared, which uses the connection of the pressure lever and the gear to indirectly drive the workpiece to be driven to rotate. However, when the workpiece to be driven is too tight, the force may be transmitted back to the gear. The gear is damaged, and when the gear is damaged, there is no other means to drive it, and the pressure handle is easy to accidentally touch, which is not only dangerous, but also reduces its service life.

Therefore, how to improve the efficiency and durability of continuous driving, and take into account the second driving method, is the direction in which the driving tool should be improved.

The main purpose of the present invention is to provide a driving tool, which can make the driving operation extremely labor-saving and efficient, and has two modes of fast driving and general driving to perform the operation.

The first driving member is connected to the second driving member by the unidirectional rotating structure. When the first driving member rotates in a first direction, it can be synchronized by the unidirectional rotating structure Driving the second driving member to rotate, when the first driving member rotates in a second direction opposite to the first direction, the unidirectional rotation structure prevents the second driving member from being synchronously driven and rotated by the first driving member The pressing lever includes a driving tooth row, the driving tooth row meshes with the first driving tooth portion of the first driving member and can drive the first driving member toward the first direction or the first by the movement of the pressing lever Two directions of rotation; the toothed rod is provided in the housing between the driven area and the driving area, and opposite ends of the toothed rod are respectively provided with a ring-shaped first transmission tooth portion and a second transmission tooth portion , The first transmission tooth portion meshes with the driven tooth portion of the at least one follower member so that the gear bar can drive the at least one driven member to rotate, and the second drive tooth portion and the second drive member of the second drive The meshing of the teeth enables the second driving member to drive the gear bar to rotate.

In other words, the reinforcing member 70 includes a ring portion and a frame portion. The ring portion is sleeved on the end of the first portion 101. The frame portion extends with the vertical direction as the axis and extends away from the second portion 102. At one end of the first part 101, the first driving member 31, the second driving member 32, the tooth row member 42 and other elements are surrounded by the frame part. With the reinforcing member 70, the transmission power is not concentrated only on The middle section of the casing 10 can be dispersed to the rear end of the casing 10 to prevent the casing 10 from being damaged.

In use, when the user continues to press the handle 40 repeatedly, the gear member 42, the first driving member 31, the second driving member 32, and the rack bar 50 can indirectly drive the driven member 21 to rotate Then, the working head 22 is driven to rotate through the first detent block 23 to achieve the effect of continuously driving the workpiece. Due to the unidirectional rotation structure, although the driving tooth row 421 has been in mesh with the first driving tooth portion 311, only A single direction will drive the second driving member 32 to rotate. In addition, if you want to change the driving direction of the working head 22, you can switch the driving direction through the rotating part 222; in addition, the second detent block 26 also provides Another driving means, that is to say, even without using the handle 40, turning the housing 10 back and forth can drive the working head 22,

In addition, when the driving tool is not used, the pressing lever 40 can be pressed into the casing 10, and then the positioning member 60 can be slid to insert the positioning portion 61 into the positioning hole 411 of the pressing lever 40. The handle 40 cannot be pivoted outward, and the effect of storing the handle 40 and avoiding accidental pressure can be achieved. To reuse it, only the positioning member 60 needs to be slid away, so that the positioning portion 61 is separated from the positioning hole 411 of the handle 40. The lever 40 will be pivoted outward to the usable position by the elastic force of the tension spring 412.

In summary, the driving tool provided by the present invention can continuously drive the working head to rotate with a simple repeated pressing operation, which is labor-saving and convenient, and has another driving means and can also be driven by a general manual pulling method. In addition, the pressing handle It can be stored to avoid accidental touch and dust, which is very effective for improvement.
