At present, all be to bear hitting power with plastic casing on the market gas staple gun, wherein the endoporus of plastic casing bottom cooperates the location with the cylindrical of cylinder bottom, and the bottom of cylinder is to be positioned on the step of plastic casing, because the not machinability of plastic casing and the distortion after the plastic shaping and change in size all can cause the axial line disalignment of cylinder axial line and plastic casing, and can cause cylinder to change in axial size, and make the installation of cylinder and ailhead seat also axial deviation can occur.In addition, the cylinder head of all gas staple guns all is to be connected with pre-buried screw on the plastic casing top in the market, causes like this skew of cylinder head and cylinder occurrence positions.The high temperature that causes owing to igniting, burning, blast in the use procedure of whole gas staple gun can make its plastic casing occur softening and expand, and has caused this product that change in size in use all can occur, or length variations.And more seriously: each igniting blast all can make plastic casing axially impact, and the trend of drawing crack is arranged.Behind the general nailing tens0000 times, this plastic casing will break.
The utility model content
The purpose of this utility model just provides that a kind of can to cancel plastic casing stressed, improves service precision and the gas staple gun in service life.
To achieve these goals, by the following technical solutions: a kind of gas staple gun, the adiabatic outer cover that comprises cylinder block and cylinder block outside, it is characterized in that: be provided with plural connection boss on the circumference external diameter of described cylinder block, have the passage that air-flow passes through between the connection boss, connect boss and link to each other the bar-shaped trough that wherein has air-flow to pass through on the terminal pad by bolt with terminal pad, one end of joint pin is connected on the terminal pad, and the other end links to each other with the cylinder head that is positioned at cylinder block top.
Wherein has the location annulus on the outer rim of terminal pad, the bottom of cylinder block has hangnail, the adiabatic outer cover of cylinder block outside is divided into heat insulation upper shield and two parts of heat insulation lower shield, the lower diameter of heat insulation lower shield is less than upper diameter, wherein the upper end of heat insulation upper shield is sandwiched between cylinder head cover and the cylinder head, the lower end is installed on the one side of the location annulus of terminal pad, and heat insulation lower shield upper end is installed on the another side of the location annulus of terminal pad, and heat insulation lower shield lower end is blocked by hangnail.
Be provided with the retainer of the half opening that holds joint pin on the inwall of described heat insulation upper shield.
Described heat insulation upper shield armrest has a side chamber that gas cylinder and the lever of calming the anger are installed, this chamber and heat insulation upper shield are a monolithic construction, because the retainer of half opening makes its this chamber can well guarantee the position of gas cylinder with the firm connection of joint pin and cylinder head, terminal pad.
Have end play between the upper end of described heat insulation upper shield and cylinder head cover and the cylinder head, have radial clearance between the outer wall of heat insulation lower shield lower end and cylinder block.
This utility model project organization is compact, easy, and accurate positioning between the parts, positioning accuracy are high, and the antifatigue impulsive force is strong, can prolong the service life of product, cuts down finished cost.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further.
Extremely shown in Figure 6 such as Fig. 1, a kind of gas staple gun, the adiabatic outer cover that comprises cylinder block 5 and cylinder block outside, be provided with plural connection boss 5-1 on the circumference external diameter of described cylinder block 5, have the passage that air-flow passes through between the connection boss 5-1, connect boss and link to each other the bar-shaped trough 4-1 that wherein has air-flow to pass through on the terminal pad by bolt with terminal pad 4, one end of joint pin 8 is connected on the terminal pad 4, and the other end links to each other with the cylinder head 2 that is positioned at cylinder block top.Wherein has location annulus 4-2 on the outer rim of terminal pad, the bottom of cylinder block has hangnail, the adiabatic outer cover of cylinder block outside is divided into heat insulation upper shield 3 and 6 two parts of heat insulation lower shield, the lower diameter of heat insulation lower shield is less than upper diameter, wherein the upper end of heat insulation upper shield is sandwiched between cylinder head cover 1 and the cylinder head 2, the lower end is installed on the one side of the location annulus of terminal pad, and heat insulation lower shield upper end is installed on the another side of the location annulus of terminal pad, and heat insulation lower shield lower end is blocked by hangnail.Heat insulation upper shield armrest has a side chamber 3-2 that gas cylinder and the lever of calming the anger are installed, this chamber and heat insulation upper shield are a monolithic construction, because the retainer of half opening makes its this chamber can well guarantee the position of gas cylinder with the firm connection of joint pin and cylinder head, terminal pad.
