INSTRUCTIONS: [Technology of the invention] The present invention relates to a pneumatic nailing device, and in particular to a configuration technique of a pneumatic nail gun provided with a movable cylinder, a sliding sleeve and a positioning valve. [Prior Art] A pneumatic nailing device, which is a type of pneumatic hand tool that uses a piston rod to fire a piston rod to a pressurized air, has been widely used for carpentry nailing operations. "In the prior art, the body of the gun is smashed, most of which have a fixed cylinder, and the piston can be pressed in the gas red, and the user can press the trigger to make the high-pressure air enter the gas. To drive the piston to move down the nail quickly. And the periphery of the gas rainbow has a plenum (or a return air chamber), which can accumulate the high-pressure air introduced through the air holes in the cylinder wall when the piston moves down, and drives the piston to move up after the piston moves down to the bottom position. Reset. However, the effect of hoarding high-pressure air in the plenum is not ideal, because the plenum can only introduce high-pressure air during the downward movement of the piston and move it over the piston (the latter can no longer receive high-pressure air continuously, so that it can drive the piston The thrust of the up-and-reset reset is extremely limited, and the problem of poor stability when the piston is moved up and reset, especially in the process of continuous stapling, is easy to move up due to the piston = slower or unstable, * affected The rate and the success of the continuous firing of the nail can overcome this problem. In the prior art, it has been found that the deliberately increase the space of the set = to increase the high-pressure air inventory in the gas-collecting chamber, but the effect is still not satisfactory. The taste of the present invention has been previously proposed by the inventor of the invention patent No. 095124436. The case has been described in the gun body configuration - movable cylinder and a sliding sleeve 6 200824857 valve, which can stably switch the lower piston and the upper piston. The high-pressure air circuit at the time of resetting, in particular, enables the high-pressure air to be continuously introduced into a gas chamber that can drive the piston up and reset, so that the gas chamber can be continuously maintained when the piston is moved up and reset. The constant pressure high-pressure air is more rapid and stable to promote the piston up-shift reset, so as to overcome the problem that the above-mentioned plenum (or return air chamber) hoards a limited high-pressure air, which may cause poor stability when the piston is moved up and reset. The structural configuration of the above-mentioned application No. 095124436 still has room for improvement, in particular, a plurality of top layers are provided on the movable cylinder. The hole positions of the valve hole and the middle valve hole, and the sliding sleeve valve must be disposed.

" Another object of the present invention is to use the high pressure air to drive the sliding valve up and down to reset In addition to the use of the spring push slide valve to move down the reset design, in order to reduce the number of components, and save production costs. In order to achieve the above objectives, the body of the present invention forms a high pressure air for a certain constant pressure The main air chamber, and a trigger is set on the body, and a movable cylinder is set in the body. A piston for the nail is arranged in the cylinder, and a movable sliding sleeve valve is arranged on the periphery of the cylinder, and a bottom of the sliding sleeve valve is formed. The bottom gas valve partitions the interior of the gun body into a first gas between the top of the head valve and the inner wall of the gun. 200824857 to a second one between the bottom end of the head valve and the inner wall of the body: the valve and the body The third air chamber between the inner walls, and - the outer part of the sliding sleeve valve: the inner wall ^ the fourth air chamber, and each gas _ main _ ^ 围 and rob according to the above-mentioned plunging body configuration environment, the present invention Forming a plurality of top floors connected to the third air chamber:; layer: =, r_r: r: > courtesy, when the trigger is pressed, the high pressure air in the first air chamber, the high pressure air in the chamber is driven upwards The positioning valve opens the gas passage of the first high second hole to guide the second air chamber and the third air chamber Day ^ hold, enter the popular red inside to drive the piston to move the nail; and, in the outgassing chamber s pressure: the layer valve hole vents the third air chamber high pressure air pressure drop, the fourth push ^ drive the sliding sleeve valve up, open the bottom layer The gas valve and the guide bow U are only inserted into the bottom of the cylinder to drive the piston to move up and down quickly. The invention can simplify the valve hole position on the gas red in the basic requirement of driving the piston to move up and down quickly, so it has the simplified gun ", the complexity and the saving of the cylinder processing cost. The utility. In addition to the above, the outer wall of the top layer of the sliding sleeve valve of the present invention may also form an outer surface, a step surface, a plurality of air sealing gaskets disposed on the step surface and the lower end of the sliding sleeve valve soil A, and between the plurality of air sealing gaskets The inner wall of the gun is provided with a pressure-reducing hole leading to the outer Lt, which acts to reduce the pressure on the step surface to offset the high-pressure air, accumulation and thrust. Accordingly, the present invention can be driven by high-pressure air, and can be moved up and down, so that the spring-loading of the sliding sleeve and the spring arrangement can be eliminated. 200824857 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 The main air chamber 13 of the group, (4), = has the grip portion 12 formed in the grip portion 12 - Fig. 2 -,::, 'supply and maintain a certain constant pressure of high pressure air (with the machine Η 1 1 is provided - Pulling the button for the user to buckle or release - the trigger 阙ΐ4ι implanted in the main air chamber 13 to drive the Goryeo air firing nail member (shown in Figures 3 and 4); 昉, Α: moving The cylinder 2 is disposed in the above-mentioned grab body 1 and is moved up by the driving of the compressed air 14 (1) as shown in FIG. 3, and is driven by the high-pressure air to move downward when the plate 4 is released.
