[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0037] Example 1: A Japanese-style cutter head with uniform cutter arrangement, see [link to example]. Figures 1 to 4 It includes a Japanese-style cutter head body 1 and a tool holder 2; the Japanese-style cutter head body 1 is arranged at the cutter head holder of the drilling equipment; several tool holders 2 are sequentially pushed into the Japanese-style cutter head body 1; wherein, the two ends of the base of the tool holder 2 are respectively positioned and engaged with several positioning structures 3 arranged on both sides of the Japanese-style cutter head body 1.

[0038] The positioning structure 3 includes a connecting plate 301 and an abutment spring 303. The connecting plate 301 is correspondingly arranged at the through groove 101 opened on the top side of the Japanese-style cutter head body 1. The two ends of the connecting plate 301 are fixedly connected to the top side of the Japanese-style cutter head body 1 by screws 302. The abutment spring 303 is arranged inside the connecting plate 301. The abutment spring 303 passes through the through groove 101 and abuts against the slot 201 opened on the side of the base of the cutter holder 2.

[0039] This utility model, by setting up a connecting plate 301, an abutment spring 303, and a slot 201, has the advantage that after the tool holder 2 is pushed into the Japanese-style tool turret body 1, the tool holder 2 is positioned by the abutment spring 303 and the slot 201. This solves the problem that the tool holder 2 on the tool turret is not stable after being pushed in, and once it deviates, it affects the use of the tool head.

[0040] Specifically, the bottom side of the base of the tool holder 2 is provided with an arc-shaped groove, and the bottom side of the Japanese-style cutting disc body 1 is provided with several arc-shaped protrusions. The protrusions slide in conjunction with the arc-shaped groove, and the tool holder 2 is stably pushed into the Japanese-style cutting disc body 1.

[0041] Furthermore, the abutment spring 303 has an arc-shaped structure design, and the arched end of the abutment spring 303 abuts and engages with the slot 201. The arc-shaped abutment spring 303 is smoothly compressed during the process of being pushed into the tool holder 2.

[0042] Furthermore, limit structures 4 are arranged at both ends of the Japanese-style cutter head body 1;

[0043] The limiting structure 4 includes a fixing strip 401 and a stop strip 402; the fixing strip 401 is fixed to the bottom side of the Japanese-style cutter head body 1; the stop strip 402 is arranged above the fixing strip 401; there are two telescopic rod bodies 403 symmetrically arranged between the stop strip 402 and the fixing strip 401, the two ends of the telescopic rod bodies 403 are fixedly connected to the stop strip 402 and the fixing strip 401 respectively, and a spring 404 is sleeved on the telescopic rod bodies 403, the two ends of the spring 404 are fixedly connected to the stop strip 402 and the fixing strip 401 respectively, and the elastic coefficient of the spring 404 is selected and used by the technical personnel in this field according to the actual situation; the stop strip 402 is matched with the bottom limiting mechanism of the cutter holder 2.

[0044] This utility model, by setting a fixing strip 401, a stop strip 402, a telescopic rod body 403 and a spring 404, has the advantage that after the tool holder 2 is installed on the Japanese-style cutter head body 1, the stop strip 402 limits the tool holder 2, and the tool holder 2 remains stable on the Japanese-style cutter head body 1 and does not fall off.

[0045] It is worth noting that a pressure plate 405 is fixed on the outside of the stop bar 402, and pressing the pressure plate 405 facilitates the downward movement of the stop bar 402.

[0046] Working principle: Using the device of this utility model, the Japanese-style cutter head body 1 is arranged at the cutter head holder of the drilling equipment. On the mounting side of the Japanese-style cutter head body 1, pressing the pressure plate 405 downward causes the stop bar 402 to move downward, the telescopic rod body 403 to shorten, and the spring 404 to compress. The cutter holder 2 is pushed into the Japanese-style cutter head body 1 in sequence. The arc-shaped groove moves along the raised bar. When the side end of the cutter holder 2 passes the abutment spring 303, it squeezes the arc-shaped abutment spring 303. The arc-shaped abutment spring 303 enters the through groove 101. After the cutter holder 2 passes, the abutment spring 303 pops out until the cutter holder 2 moves to the corresponding position. The arched end of the arc-shaped abutment spring 303 engages with the corresponding through groove 101 to abut and position the cutter holder 2. After the cutter holder 2 is fully installed, the pressure plate 405 is released. Under the action of the spring 404, the stop bar 402 moves upward until the stop bar 402 is limited to the bottom of the cutter holder 2.

[0047] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
