[0020] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-Figure 3 As shown, the utility model proposes a new type of fixture, which includes a first component 100, a second component 200, a first fixing member 300 and a fastener 400. The first component 100 is provided with a first hole 101 and a plurality of second holes 102 connected to the first hole 101. The second component 200 can be movably embedded in the first hole 101. The first fixing member 300 can be movably installed in the second hole 102 and connected to the second component 200. The movement of the second component 200 in the first hole 101 can drive the first fixing member 300 to extend or retract into the second hole 102. The fastener 400 is installed on the first component 100 to cooperate with the first fixing member 300 to fix the tool.

[0022] Specifically, in this embodiment, the clamped tool takes a pre-milling tool as an example. The first component 100 and the second component 200 adopt a tubular structure to adapt to the inner diameter hole of the pre-milling tool. Multiple second holes 102 are evenly arranged on the first component 100 and are all connected to the first hole 101 and the second component 200 in the first hole 101. When the pre-milling tool is sleeved on the first component 100, by driving the second component 200 to move in the first hole 101, the first fixing member 300 extends out of the second hole 102 to conflict with the inner diameter of the pre-milling tool, thereby achieving the clamping of the pre-milling tool. It should be noted that the distance that the first fixing member 300 extends out of the second hole 102 is to achieve adaptation to pre-milling tools with different inner diameters, thereby improving versatility, and only by controlling the movement of the second component 200 in the first hole 101, the first fixing member 300 can be driven to extend or retract into the second hole 102, thereby achieving quick disassembly and assembly of the pre-milling tool.

[0023] Furthermore, the second component 200 includes a second fixing member 201, a movable shaft 202 and an elastic member 203. The movable shaft 202 is installed in the first hole 101 through the second fixing member 201. The elastic member 203 is installed in the first hole 101. The two ends of the elastic member 203 are respectively connected to the bottom of the first hole 101 and the movable shaft 202.

[0024] Specifically, in this embodiment, the second fixing member 201 is a bolt structure, the movable shaft 202 is provided with a through hole and an inner cavity, and the elastic member 203 is a coil spring structure, as shown in the attached Figure 2 As shown, the elastic member 203 is placed in the inner cavity of the movable shaft 202, and when the movable shaft 202 is installed in the first hole 101, the elastic member 203 conflicts with the bottom of the first hole 101. A threaded hole is provided at the bottom of the first hole 101, and the second fixing member 201 penetrates the through hole and the inner cavity of the movable shaft 202, and cooperates with the threaded hole to restrict the second component 200 in the first hole 101. It should be explained here that the second fixing member 201 is directly penetrated into the through hole of the movable shaft 202 and has no direct connection relationship. The movable shaft 202 can still move in the first hole 101, but the setting of the elastic member 203 further restricts the movable shaft 202, so that the movement of the movable shaft 202 in the first hole 101 is controlled by the cooperation of the second fixing member 201 and the elastic member 203.

[0025] Furthermore, an inclined surface 2021 is provided on the outer wall of the movable shaft 202 , and the first fixing member 300 contacts the inclined surface 2021 and moves along the direction of the inclined surface 2021 to extend or retract into the second hole 102 .

[0026] Specifically, the second fixing member 201 is continuously tightened and drives the movable shaft 202 close to the bottom of the first hole 101. At this time, the high point of the inclined surface 2021 conflicts with the first fixing member 300, so that the first fixing member 300 extends a larger distance from the second hole 102. On the contrary, the second fixing member 201 is loosened. Due to the action of the elastic member 203, the movable shaft 202 continues to move away from the bottom of the first hole 101, so that the first fixing member 300 moves from the high point of the inclined surface 2021 to the low point. At this time, the first fixing member 300 extends a smaller distance from the second hole 102 or even retracts into the second hole 102, thereby realizing rapid disassembly and assembly of tools with different inner diameters. It should be noted that since multiple first fixing members 300 are driven to extend or retract into the second hole 102 by multiple inclined surfaces 2021 on the movable shaft 202, the assembled tools can be maintained on the central axis of the new fixture.

[0027] Furthermore, the first fixing member 300 includes a ball, specifically a tungsten steel ball. Other structures in the novel fixture, such as the first component 100 and the second component 200, are all made of high-hardness materials.

[0028] Furthermore, the novel fixture further includes a plurality of limiting members 500 , which are respectively fixed to the plurality of second holes 102 to limit the first fixing member 300 from extending out of the second hole 102 .

[0029] Specifically, the limiting member 500 in this embodiment adopts a screw structure, and limits the movable distance of the first fixing member 300 in the second hole 102 through the screw head on the screw.

[0030] Furthermore, a stop block 103 is provided on the first end of the first component 100, and the fastener 400 is threadedly engaged with the second end of the first component 100. Through the threaded engagement, the fastener 400 approaches the stop block 103 and cooperates with the stop block 103 to clamp the tool.

[0031] The fastener 400 includes a fastening ring 401 and a gasket 402. The fastening ring 401 is threadedly engaged with the second end of the first component 100 (not shown in the figure). The gasket 402 is sleeved on the second component 200 and placed between the block and the fastening ring 401. The fastening ring 401 is threadedly engaged with the second end of the first component 100 to push the gasket 402 closer to or away from the block.

[0032] See attached Figure 2, multiple first fixing members 300 are in contact with the inner diameter hole of the tool to achieve clamping of the tool. At this time, the tool cannot be clamped more firmly here. Therefore, the tool is clamped therein by cooperating with the block 103 and the fastener 400 to enhance the stability of the clamping. In this embodiment, the fastener 400 includes a fastening ring 401 and a gasket 402. Since the fastening ring 401 is threadedly engaged with the second end of the first component 100, the thread engagement here will cause the contact surface of the fastening ring 401 to be in an inclined state. If the fastening ring 401 is directly used to contact the tool, it is easy to cause the tool to be unable to be concentric with the new fixture, thereby affecting the accuracy. Therefore, a gasket 402 structure is added. The gasket 402 serves as a medium for the fastening ring 401 to contact the tool, and the gasket 402 has no connection relationship such as thread engagement. Therefore, the contact surface of the gasket 402 can be guaranteed to be parallel to the tool, ensuring that the tool remains concentric with the new fixture after clamping.

Any similarity or similarity with the methods, structures, etc. of the present invention, or any technical deduction or substitution based on the concept of the present invention, shall be deemed to be within the scope of protection of the present invention.
