Description

Pneumatic tool structure improvement (3)

This creation provides a pneumatic tool, especially a structural improvement of a pneumatic tool that is simple in structure and suitable for left and right hand operation, and can be operated with one hand and comfortable to hold and easy to switch (3).

According to the pneumatic tool, it is a very important tool for the construction of today or for the locking and disassembly of screws and bolts. However, under the ever-changing improvement, the pneumatic tool can switch its rotation direction to achieve the lock or loose. Purpose, however, the switching direction of the conventional pneumatic tool is mainly in three ways. One is to use the direction switching valve body/knob to switch. This structure is simple, but it needs to be held by one hand when switching the knob. The tool rotates the knob with the other hand at the same time, so it is very inconvenient to stop the operation process and switch between the two hands at the same time. The other is that the pressing button can be used to achieve the switching direction, but this design structure The production process is more complicated, resulting in higher costs.

The third type is to switch the valve body to the opposite sides of the valve in the direction of the rear of the machine. No matter whether the left or right hand user pushes one of the levers up and down with the finger, the direction of the tool rotation can be switched. The opposite two levers act as a seesaw, and when the one side is pulled downward, the other side lever is rotated downward from the bottom, and vice versa. However, when the lever is actually pulled, the palm or face of the left or right hand user will be seriously disturbed or even unable to hold. In order to reduce such interference, there are also ways to shorten the two relative levers, but this will definitely cause difficulty in the movement.

Therefore, how to solve the above problems and shortcomings in the past, that is, the creators of the creation and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.

Therefore, the creators of this creation, in view of the above-mentioned deficiencies, are collecting relevant information, and through multi-party evaluation and consideration, and through years of experience in the industry, through continuous trial and modification, the design of this structure is simple and convenient to switch. And it can be improved by any one-handed operation and switching direction of the pneumatic tool structure (3) new patents.

The main purpose of this creation is to make breakthroughs in the problems of simple structure but inconvenient switching or convenient switching but complicated structure for the conventional pneumatic tools, and to achieve practical and progressive convenience of simple structure switching.

In order to achieve the above purpose, the present invention creates a pneumatic tool structure improvement (3), which comprises a control device for arranging a ram which is supported by the trigger machine, and the control device comprises: a direction switching lever and a direction switching valve body, a direction switching lever The central portion defines a sliding portion that is sleeved on the ejector pin, and the direction switching rod is disposed through the direction switching valve body, and the two ends of the direction switching rod respectively form a plurality of resisting portions, and the resisting portion extends out of the direction switching valve In addition to the body, the abutting portion can resist the outer side wall of the direction switching valve, and the direction switching rod is adjacent to the sliding portion to define a limiting portion for resisting the wall surface of the through hole, and the through hole is defined by the direction switching valve At the side of the body, the direction switching valve system is sleeved on the jack, and the direction switching valve system defines and houses and limits the through hole of the direction switching lever position, and the direction switching valve system is connected to switch the adjusting component of the pneumatic tool steering. When the user replaces the operation between the right and left hands, it is only necessary to use the pressing direction switching lever to the other end, that is, the left-hand finger or the right-hand finger can be used for steering switching to speed up the manipulation. The control device can further include a speed adjustment knob for adjusting the air intake amount of the pneumatic tool, and the speed control knob is sleeved on the ejector pin and located between the direction switching valve body and the trigger machine, and the speed control knob is The indication area of the display speed is defined, thereby facilitating the adjustment of the steering and the rotation speed, and achieving the practical progress of simple structure and convenient switching.

In order to achieve the above objectives and effects, the technical means and structure adopted by the present invention are described in detail in the preferred embodiment of the present creation, and the features and functions are as follows.
