[0023] Below, the invention is further described in conjunction with the accompanying drawings and specific embodiments: Embodiment 1:

[0024] See also Figure 1-3 According to a cemented carbide tool length control device of an embodiment of the utility model, a through groove 2 for clamping the tool is provided on one side of the sleeve 1, a roller 3 for pressing the tool is provided in the through groove 2, and a pattern for increasing friction is provided on the outer wall of the roller 3, an adjusting component 4 is connected to one side of the roller 3, and a moving component 5 is connected to the other side of the roller 3.

[0025] According to the above scheme of the utility model, the alloy tool can be loaded into the through slot 2 provided in the sleeve 1, and then the turntable 41 is rotated to drive the roller 3 to rotate, and the roller 3 drives the gear 52 to rotate through the torque unit 54, so that the gear 52 rolls down along the tooth groove 53, so that the roller 3 moves down and squeezes the alloy tool, and after the roller 3 contacts the alloy tool, pressure is applied to the alloy tool, and as the turntable 41 continues to rotate, the gear 52 will continue to move down with the roller 3, and the alloy tool will block the roller 3 from moving down, so when the torque is large, After the spring 543 provides support force to the ball 542, the ball 542 will be pressed into the spring groove 10 by the groove of the gear 52, so that the ball 542 is separated from the gear 52, so that the roller 3 rotates while the gear 52 does not rotate, so that the alloy tool is pushed to move in the through groove 2 by the rotation of the roller 3, and the length of the alloy tool is adjusted, which effectively improves the installation efficiency of the alloy tool. The pattern provided on the outer wall of the roller 3 can increase the friction between the roller 3 and the alloy tool during contact, so that the alloy tool can be pushed to move more easily when the roller 3 rotates. Embodiment 2:

[0026] See also Figure 1-2 The adjusting component 4 includes a turntable 41, a slider 42 and a slide groove 43. A slide groove 43 is provided on the outer wall of the casing 1 on one side close to the roller 3. The slider 42 is slidably connected in the slide groove 43. A rotating shaft is rotatably connected in the slider 42. One end of the rotating shaft located in the through groove 2 is fixedly connected to the roller 3. The end of the rotating shaft located at the crooked end of the casing 1 is connected to the turntable 41. The two side walls of the slider 42 in contact with the slide groove 43 are both protruding to form a baffle 6. The two inner side walls of the slide groove 43 are both provided with a track groove 7 that matches the baffle 6. The outer wall of the turntable 41 is equidistantly provided with a plurality of gear levers 8 formed by protrusions, and the outer walls of the gear levers 8 are all covered with a silicone sleeve 9.

[0027] Through the above-mentioned scheme of the utility model, by providing multiple gear levers 8 on the outer wall of the turntable 41, the turntable 41 can be better leveraged when rotating, making the rotation of the turntable 41 easier, and the silicone sleeve 9 is sleeved on the outer wall of the gear lever 8, which can reduce the pressure between the hand and the gear lever 8, thereby improving the comfort when rotating the turntable 41. When the turntable 41 rotates and drives the roller 3 to move downward, the slider 42 will move downward in the slide groove 43. By providing the baffles 6 on both sides of the slider 42 and the track groove 7 slotted in the slide groove 43, the sliding stability of the slider 42 can be improved, and the moving path of the slider 42 in the slide groove 43 can be restricted, which will inevitably cause the slider 42 to tilt and cause the roller 3 to be unable to contact the alloy tool normally. Embodiment three:

[0028] See also Figure 2-3 The moving assembly 5 includes a moving block 51, a gear 52, a tooth groove 53 and a torque unit 54. The inner wall of the through slot 2 away from the slide slot 43 is provided with a tooth groove 53, and the moving block 51 is slidably connected in the tooth groove 53. The moving block 51 is rotatably connected with a gear 52 meshing with the tooth groove 53. The side of the gear 52 close to the roller 3 is connected to the roller 3 through the torsion unit 54. The torsion unit 54 includes a connecting shaft 541, a ball 542 and a spring 543. One end of the connecting shaft 541 is fixedly connected to the roller 3, and the other end of the connecting shaft 541 is rotatably connected to the gear 52. A plurality of spring grooves 10 formed by concave inwards are provided on the side of the connecting shaft 541 close to the gear 52, and the spring grooves 10 are all slidably connected with balls 542. A spring 543 is fixedly connected between the balls 542 and the spring grooves 10, and a slot matching the balls 542 is provided on one side of the gear 52.

[0029] Through the above scheme of the utility model, the gear 52 is meshed with the tooth groove 53, so that when the gear 52 rotates, it will move along the tooth groove 53, thereby driving the roller 3 to move up or down, so that the tool holder can quickly clamp the alloy tool. After the roller 3 clamps the alloy tool, as the turntable 41 continues to rotate, the torsion between the connecting shaft 541 and the gear 52 increases. When the torsion is greater than the supporting force applied by the spring 543 to the ball 542, the ball 542 is pressed into the spring groove 10 to separate the roller 3 from the gear 52, so that the roller 3 idles, and then the alloy tool is pushed to move in the through groove 2 by the rotation of the roller 3, so that the tool length is adjusted, and the moving block 51 (see Figure 4 ), by moving the block 51 in contact with the inner wall of one side of the tooth groove 53, the gear 52 will not deviate during the movement, ensuring that the gear 52 can stably mesh with the tooth groove 53.

[0030] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0031] In actual application, the alloy tool is inserted into the through groove 2, and then the turntable 41 is rotated to make the roller 3 approach and squeeze the alloy tool. As the turntable 41 continues to rotate, the roller 3 will rotate while the gear 52 will not rotate, so that the roller 3 rotates to push the alloy tool to move, thereby achieving the adjustment of the length of the alloy tool. At the same time, the roller 3 can also maintain the pressure applied to the alloy tool to fix the alloy tool.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
