The handle 19 can be grasped and the surface set start stop controls can control the operation of the driver.

The handshake 27 is incremented.

The booster grip 27 limits the rotation of the surface on the left side of the booster housing 1 and the surface of the booster grip has an interference fit with two and/or more metering rods 28 for assisting in positioning the angle and/or distance.

The force-increasing handle 27 can be held by two hands, can be better stressed when a hole is drilled at the top, and meanwhile, the force-increasing handle 27 can rotate and is not fixed, and is in a limiting sleeved state on the surface of the force-increasing handle, and as can be seen by combining with the figure 15, the force-increasing handle can rotate at a certain angle, so that the force application of the two hands is facilitated;

the measuring rods 28 on the surfaces of the enhanced handles can measure the drilling depth, and the measuring rods 28 are attached to the wall body under the matching of the lengths of the measuring rods, so that the support in an inclined state can be kept, and the stability is improved.

Specifically, as shown in fig. 4 and 5: the method comprises the following steps:

inner circulation fan 21.

The inner circulation fan blade 21 is positioned at the right side of the firing assembly 5 and is fixedly arranged at the left end of the rotor 13.

The air outlet 26 of the reinforced shell 1 on the arc-shaped side wall of the internal circulation fan 21 is provided with a plurality of air outlets 26, and the air inlet 25 of the reinforced shell 1 on the speed increasing assembly 8 is provided.

The internal circulation fan blades 21 can keep the directional flow of air flow, external air flow enters through the air inlet 25 and can directly cool the position of the electric brush assembly 9, then the air flow passes through the driver, carries heat and enters the internal circulation fan blades 21, and then is discharged through the air outlet 26, and the internal temperature is effectively controlled.

Specifically, as shown in fig. 15 and 16: the method comprises the following steps:

a mating nail 11.

The matched nail 11 is placed at one end of the excitation kit 10 and is nailed into the wall after being triggered.

FIG. 15 is a schematic view of the firing assembly 5 and associated staples 11 in an installed position, as can be seen in use.

The firing assembly 5 comprises a clamping sleeve 101 which is connected with the clamping seat 16 in a matched mode, a firing hammer 102 is arranged on the inner wall of the clamping sleeve 101 in a limiting and reciprocating sliding mode, a fitting head 103 which is in a concave disc shape is arranged on one side of the clamping sleeve 101, and a plurality of slow flow holes 104 used for air to flow in and out are formed in the surface of the clamping sleeve 101.

The effect of the slow flow hole 104 needs to be known, the slow flow hole 104 can effectively prolong the service life of the excitation kit 10, and it can be seen from fig. 16 that the space of the inner wall of the ferrule 101 is similar to a step shape, when the percussion hammer 102 impacts the matched nail 11, the percussion hammer 102 actually moves to the step junction inside the ferrule 101 at this time, and at this time, the percussion hammer 102 and the inner wall of the ferrule 101 are in a fit state, so that the gas is discharged through the slow flow hole 104, the gas flow rate is limited, so that the percussion hammer 102 can buffer, and the percussion hammer 102 is prevented from rigidly impacting the inner wall of the ferrule 101.

The matched nail 11 comprises a firing seat 113 which is in interference fit with the end of the cutting sleeve 101, a nail head 111 is arranged on one side of the firing seat 113, and a positioning plate 112 which is in fit contact with the fitting head 103 to calibrate the center is arranged at one end of the nail head 111.

Through setting up spacer 112, spacer 112 we adopt the material of plastics, can carry out the direction calibration with laminating head 103, simultaneously behind pin head 111 percussion because the windage effect down, spacer 112 can separate with it.
