Description of the new type: [Technical field to which the new type belongs] This creation belongs to the technical field of woodworking machinery, especially a woodworking tool. [Prior technology] Among the woodworking machinery, the tools used to cut the surface of the wood are as shown in Figures 3 and 4 (that is, the first and second figures of the new patent case No. 398402 "Good for woodworking flat knives") The following is referred to as Case No. 1). There are several spiral steps (41) on the periphery of the cylindrical body (40), and several sipes (42) are equidistantly arranged on the rib steps (41). The bottom of the sipe (42) is provided with an orthodontic screw hole (43), and another bolt (4 4) with two sections rotating in different directions, a inflammation block (4 5), and a blade (46) are provided. The clamping block (45) has a reverse tooth screw hole (451) which is opposite to the normal tooth screw hole (43) of the sipe (42). The two sections of the screw loose (4 4) are screwed to the knife respectively. The teeth of the orthodontic screw (43) of the groove (4 2) and the reverse of the tooth screw (451) of the clamping block (45), and then the blade (46) is clamped between the clamping block (45) and the sipe (42). —Between the peripheral walls' When the rotating screw inspection (4 4) moves the clamping block (4 5) toward the side of the bottom of the slot (42), the blade (46) can be tightened by the slope of the block. However, 'because the end face of the bolt (44) has a hexagon socket and when it locates the clamping block (4 5), the end face of the bolt (4 4) may also be buried in the anti-thread screw hole of the clamping block " 5) ( 4 5 丄) When cutting internally, although the sawdust will be thrown out under the rotation of the tool, the sawdust will still accumulate. M268166 Hexagonal recess # in the bolt (4 4) and the anti-screed screw hole (4 5 1) 'Therefore, when replacing the blade (4 6), the wood chips must be removed before the hex wrench can be inserted into the groove of the bolt (4 4), but the wood chips will accumulate in the anti-thread screw holes (4 5 1 In the root of the screw, it is quite difficult to clean it. 'If it is not cleaned, the screw (4 4) will be stuck and cannot be loosened'. Therefore, the existing inflammation block (4 5) design causes the blade to be replaced (4 6 ) Quite inconvenient. Also, the inflammation block (4 5) is mated with the sipe (4 2) on one side to fully push the blade (4 6). However, in this way, the cooperation of the two inclined surfaces must be extremely accurate, otherwise Unable to loosen the blade (4 6) 'Instead, it increases the difficulty and cost of processing. Also, another industry operator proposed an announcement No. 5 4 2 0 8 8 "Tool structure for oblique loading and unloading blades" (hereinafter referred to as Reference Case 2), which consists of a cutter, a force block, a locking ring, and a double-headed The threaded bolt is composed of many components, and still has the risk of wood chips accumulating in the hexagonal hole of the bolt and the internal thread of the lock ring. ’It is necessary to improve the clamping block of existing woodworking tools. [New content] In order to improve the above defects, the main purpose of this creation is to provide a woodworking tool positioning device with chip removal effect. Based on the above purpose, the main technical means of this creation is to have a columnar body. There are several u-shaped sipes that open outward on the periphery of the body. A cutter and a clamping block are arranged in the sipe. The cutter is clamped in the clamp. Between the block and one of the side walls of the sipe, and the bottom of the chute and the sipe are provided with internal screw holes with opposite rotation directions M268166, for a two-threaded locking bolt to fix the chuck to the sipe "Inside", the two opposite sides of the sipe are respectively set as a bevel and a pushing surface. The inclined surface is gradually inclined from the bottom of the sipe to the outside, and the tool is attached to the inclined surface; the clamping block faces the side of the tool It is set as a tight slope corresponding to the slope of the sipe, and the other side is set as a pressing surface facing the sipe, and the clamping block is far from the bottom of the groove of the sipe. The side is provided with an adjacent slope. The chip guide concave arc surface 'and a top surface which is in contact with the chip guide concave arc surface and is adjacent to the pressing surface. The top surface is in contact with the chip guide concave arc. The end is set to be higher, and within the clamping block. The screw hole runs through the top surface. After the implementation of the above technical means, since the surface of the clamping block adjacent to the tool is set as a chip guide concave arc, and the top surface and the chip guide concave arc are bent at an angle, when cutting wood, the wood chips will follow the chip guide concave arc. The surface is discharged so as not to accumulate on the reverse screw hole on the side of the top surface and the end face of the lock bolt. Therefore, when the tool is to be changed, the sawdust can be quickly cleaned, the lock bolt and the clamping block can be loosened, and the tool can be changed. [Embodiment] Since the spiral woodworking tool is similar to the aforementioned existing products, this creation only aims at improving the positioning device of the tool, and to clearly show the structure, the following creation only shows the situation of woodworking tools Alas, He Xian Chen Ming,:. As shown in the first figure, the cutting tool still includes a columnar body (10) 'There are a number of ribs inclined in a spiral line around the surface of the body (10)', and the ribs (ii) The upper space is provided with a sipe ('in: groove (12) ... a tool (20), the tool (20) is clamped and positioned by a tool positioning device (30). M268166 Please also refer to the second figure It is shown that the sipe (1 2) has a groove bottom (1 2 0), and an inclined surface (1 2 1) and a pushing surface (1 2 2) located on two opposite sides of the groove bottom (1 2 0). The inclined surface (1 2 1) is gradually inclined from the bottom of the groove (1 2 0) for the cutter (2 0) to be attached to the inclined surface (121), and the shape between the inclined surface (121) and the bottom of the groove (12) And forming an oblique angle (1 2 5) for the surface of the cutter (20) and the inclined periphery to abut against the oblique surface (1 2 1) and the oblique angle (3 2) It includes an arc-shaped groove (2 3) provided in the middle section of the abutting surface (1 2 2), and an clamping block (2 3) axially from the surface of the rib (1 1) toward the groove arc-shaped groove.

The bolt (3 2) can push the clamping block (3 丄) toward the end of the groove (12) of the sipe (12), and then press the inclined surface (31) of the clamping block (3 workers). )will The cutter (20) is pushed against the inclined surface (121) of the cutter groove (12). At the same time, the two pushing contact surfaces (122) of the sipe (12) and the two pressing contact surfaces (3 夹) of the clamping block (3 1) are kept in contact, so that the pressing slope (3 1 0) forms two ends. In the state of being pressed by force, the cutter (20) is clamped more firmly between the clamping block (31) and the inclined surface (ι 1) of the cutter groove (12). It can be clearly seen from the second figure that because the clamp block (3 1) faces outward, the surface M268166 has the concave guide surface (313) of the chip guide adjacent to the tool (20). The second guide: concave guide surface (3 1 3) _Near the top surface (3 χ 4) that end and become the same, so when cutting wood, under the high-speed rotation of the Io tool body (1 〇), the genus will follow the concave arc surface of the chip (3 1 3) is ejected, and as for Luo to 1 in the reverse screw hole (3 1 5) of the lost block (3 1) and the angle groove (322) of the lock 2). When the tool is to be changed (2 o'clock), the lock bolt (32) can be quickly unscrewed, and the clamping block (3) can be released to achieve the purpose of quick tool change (2 0).
