[0024] See also Figure 1 to Figure 3 ,in Figure 1 This is a front view of the first embodiment of the utility model. Figure 2 The utility model Figure 1 The cross-sectional view along the AA line. Figure 3 The utility model Figure 2 A partial enlarged view of point B in the middle.

[0025] The utility model provides a tool assembly structure for machining small inclined holes in a valve body, comprising a tool body 101, a clamping column 102 and a fastening mechanism, wherein the fastening mechanism comprises two screw rods 105, a fastening plate 106, a mounting seat 107 and a protective cover 114. The above-mentioned scheme solves the technical problem that the two screw rods 105 in the above-mentioned structure cannot rotate at the same time, thereby making the disassembly and assembly of the tool more troublesome.

[0026] According to this specific embodiment, the handle of the tool body 101 is semicircular, and a tool sleeve 103 is provided at one end of the clamping column 102. The tool sleeve 103 has a semicircular groove 104. The tool body 101 is slidably connected to the tool sleeve 103 and is located in the semicircular groove 104. The setting of the tool sleeve 103 can facilitate the replacement of different types of tool bodies 101, thereby improving practicality.

[0027] A limiting ring 108 is provided below the screw rod 105, and a knob 109 is provided above one of the screw rods 105, a gear 110 is provided in the middle of the screw rod 105, a limiting groove 111 is provided in the fastening plate 106, a receiving groove 112 is provided in the mounting seat 107, and two thread grooves 113 are provided on the outer side of the tool sleeve 103, the two screw rods 105 are respectively rotatably connected with the fastening plate 106 and are located in the fastening plate 106, and the limiting ring 108 is located in the limiting groove 111, the two screw rods 105 are also respectively threadedly connected with the tool sleeve 103 and are located in the corresponding thread groove 113, and the two gears 11 0 are meshed with each other and are located in the accommodating groove 112, the fastening plate 106 and the tool body 101 are mutually supported and are located on the tool body 101 and are also located in the semicircular groove 104, the mounting seat 107 is fixedly connected to the tool sleeve 103 and is located on the outside of the tool sleeve 103, and the gear 110 is arranged on the screw rod 105, and then the two gears 110 are meshed, so that the two screw rods 105 can be ensured to rotate at the same time, and under the action of the thread groove 113, the two screw rods 105 can push the fastening plate 106 at the same time, thereby making the disassembly and assembly process of the tool body 101 very simple and convenient.

[0028] Secondly, the protective cover 114 is bonded to the mounting seat 107 and is located above the mounting seat 107. The protective cover 114 can be used to protect the gear 110 and improve the aesthetics.

[0029] Again, an anti-skid pad 115 is disposed on the end surface of the fastening plate 106 . The provision of the anti-skid pad 115 can increase the friction force on the tool body 101 .

[0030] When the tool body 101 is disassembled by using the utility model, the knob 109 is rotated clockwise to make the knob 109 drive one of the screw rods 105 to rotate, and the other screw rod 105 is linked under the action of the gear 110. At this time, the two screw rods 105 move upward under the action of the thread groove 113 and the limit ring 108, and drive the fastening plate 106 away from the tool body 101. At this time, the tool body 101 can be taken out. When the tool body 101 needs to be assembled, it is only necessary to rotate the knob 109 counterclockwise to make the two screw rods 105 push the fastening plate 106 to move toward the direction of the tool body 101, and finally abut against the tool body 101, thereby improving the stability of the tool body 101. In this way, the technical problem that the two screw rods 105 in the above structure cannot rotate at the same time, thereby making the disassembly and assembly of the tool more troublesome, is solved.
