Referring to FIG. 3 to FIG. 5 and referring to FIG. 2 at the same time, the body 1〇 has a first segment 11 and a second segment 12, and the second segment u and the second segment 12 form a gap, and the body 10 further includes There is a hollow portion 13 for axially sliding the piston 2, the first portion 11 is provided with a flange lu at the opening, and a plurality of screw holes 112 and a plurality of bolt holes 113 are formed in the flange 111, and the flange is flanged. A side wall 114 is protruded from the outer periphery of hi. The second section 12 defines an air inlet hole 121 for connecting to the end of the body 1 for connection with the high-pressure air intake pipe, and the second section 12 defines a connection with the hollow portion 13. The air passage 122, and the second section 12 of the body 1 defines a connecting groove 123 communicating with the air inlet 122 in the radial direction of the body 1 , and the connecting groove 123 is provided for a control valve 14 , the control valve 14 has an open position and a closed position for controlling the connection of the inlet port 22, and the control valve 14 is provided with an elastic member 141 in the connecting groove 123 for the control valve 14 to be maintained in the closed position. The piston 20 is fitted with a hollow portion of the body 1 , and the piston 2 has a head 21 . When the piston 20 is pushed by the high pressure air input from the body 1 7 -200940273 *, the piston 20 will protrude. Outside the body 10, the head portion 21 defines a recess 22 along the end portion of the piston 2, and the recess 22 is provided with a U-shaped abutting member 23. The sleeve member 23 is sleeved on the recess 22, wherein the abutting member 23 is smooth and resistant. In the present embodiment, the abutment member 23 is embodied as an iron ring. The head portion of the piston 2 is different from the abutting member 23, and a limiting portion 24 is protruded from one end of the abutting member 23, and the limiting portion 24 is disposed in a spaced shape, and has a ring at the side of the limiting portion 24 different from the abutting member 23 The groove 25 and the ring groove 25 are mounted to prevent the high pressure air pressure from being leaked. The piston 20 has a first position and a second position in the body 1〇, so that the piston 20 can be Move between the first position and the current position. The cover 30 is annularly coupled to the inner wall surface of the hollow portion 13 of the body 1 . The cover 30 has a convex portion 31 and can abut against the flange 111 around the outer periphery of the body 1. The convex portion 31 cooperates. The bolt hole 113 of the flange ln is provided with a plurality of positioning cards • the bolt 32, wherein the positioning clip 32 can be bolted into the bolt hole 113, and the convex portion 31 cooperates with the screw hole 112 of the flange in to set the screw hole 33 for the screw The screw locks the fixed body 10 and the cover 30, and the cover 3 is provided with a plurality of receiving grooves © 35 ' on the inner ring and the receiving groove 35 is opened to the outside of the cover 30. The outer diameter of the limiting portion 24 of the piston 2 is larger than the inner diameter of the cover 3〇, so that the piston 2〇 can only protrude from the body 10 to the limiting portion 24 to the cover 30, and the limiting piston 20 can only be CENTRAL 4 13 moves 'and prevents the piston 2 〇 from being pushed by the high pressure air to pull out. Body 10. The expansion rod 40 is made of embossed pounds, and the expansion rod 4 〇 has a frame end 41, which is freely known, wherein the head of the piston can push the expansion rods 40 outwardly, and the expansion rods 40 can be borrowed. A buckle 42 is inserted through the pivoting end 41 of each of the expansion rods 40 to pivotally connect with the expansion rod, and the buckle ring connects the f expansion #40, and the free end 43 of the expansion rod 4Q can be closed by the cover 30. The outer side of the accommodating groove 35 extends to the outside of the cover 30. The 扩张 俾 allows the expansion rod 40 to be firmly coupled to the cover 3 〇, and the expansion 柃 40 can be generated in the space of the accommodating groove 35. Pivot. When the piston 2 is in the first position, the expansion rod 40 is in a contracted state, and when the piston 20 is in the second position, the expansion function 40 is in an expanded state (as shown in FIG. 8). In the first position, the control valve is in the first position. 14 is in the closed position to close the intake port 122, the piston 2 is located at the bottom of the body ίο, in the second position, the control valve m is in the open position to open the inlet 122. 'High pressure air enters the push-up expansion rod 4〇 External expansion. The cover 30 is also sleeved with an elastic shrink sleeve 5〇, and the shrink sleeve 50 is sleeved on the outer periphery of each of the expansion rods 4〇, so that the expansion rods 4G are inward by the elastic force of the sleeves under normal conditions. Convergence, convenient for dust jacket 6 〇 set. Please refer to FIG. 6 to FIG. 7 , which are cross-sectional views taken along line 6-6 and 7-7 of FIG. 5 of the present invention, showing a structure in which the body 10 and the cover 30 are positioned and fixed to each other, and the assembly is first performed. The positioning clip 32 of the cover 3 is aligned with the bolt hole 113 of the body 10, and the screw 34 is screwed with the screw holes 112, 33 of the body 1 and the cover 30. Referring to FIG. 8 , it is a use state diagram of the present invention. When the control valve 14 is pressed, the air inlet 122 of the body is in an open state, so that the piston 2 〇 pushes the expansion rods 40 outwardly, and the piston is expanded. The abutting portion 24 abuts against the cover 30 to prevent the piston 20 from coming out, wherein the abutting member 23 of the piston 2 is for contacting and rubbing the expansion rods 40, and the abutting member 23 can prevent the expansion rod 4 from directly contacting, The piston 20 is frictioned to prevent the piston 20 from expanding due to long-term wear and recession of the 200940273 material rod 4Q. Referring to FIG. 9 and FIG. 10, it is an action state diagram of the automobile dustproof cover disassembly and assembly tool of the present invention. The law is 9n # λ* . „ ^ / When the tongue plug 20 is in the first position, the dust jacket 60 sets first. Into the 'shrinkage> of the expansion rod 40, and then connect high-pressure air, to be controlled by the 214 lead air to move the piston 2q (as shown in the figure) to the second gland f to push the expansion rod 40 to expand In the state of the state, the expansion rod 40 is outwardly expanded 60. Then, the disassembly tool of the present invention is moved to install the dustproof sleeve 6 or the dust jacket 6 is removed. The above description can be summarized as follows: 1. The "automobile dust cover disassembly and assembly" of the present invention, wherein the buckle can quickly install each sea H branch, and it is required that the lion Z can be solidly expanded; ^ ' _a_ has a good ring Pulling the force to make the expansion rods force the average 'is a very progressive design. This month's 7 car dust cover disassembly tool, in which the piston is recessed with a metal ring sleeve, can effectively prevent the expansion rod from wearing the piston, and avoid the piston protrusion depression affecting the expansion degree of the expansion rod. The present invention is intended to be only a preferred embodiment of the present invention, and is not intended to limit the scope of the embodiments of the present invention. Changes in imaginary modifications should still fall within the scope of the invention patent. '...
