Detailed Description

The first embodiment of the application is as follows:

referring to fig. 1, fig. 1 is a schematic structural diagram of an alloy reamer according to a first embodiment of the utility model.

The utility model provides an alloy reamer, which comprises a spiral blade 101, a cutter handle 102 and a stabilizing mechanism 103, wherein the stabilizing mechanism 103 comprises a base 104, a stabilizing cylinder 105, two clamping plates 106, two guide plates 107, two connecting assemblies 108 and a friction pad 112; the connection assembly 108 includes a connection rod 109, a return spring 110, and balls 111. The problem that the conventional reamer is easy to roll down from the tabletop to cause damage when not in use is solved through the scheme, and it can be understood that the scheme can be used in a scene when the reamer is not in use and can also be used for solving the problem that the stability of the base 104 on the tabletop is poor.

For this embodiment, the spiral blade 101 is fixedly connected to the handle 102, and is located on one side of the handle 102, the stabilizing cylinder 105 is rotatably connected to the base 104, and is located on one side of the base 104, the two clamping plates 106 are respectively slidably connected to the stabilizing cylinder 105, and are respectively located on two sides of the handle 102, the two guide plates 107 are respectively fixedly connected to the base 104, and are respectively located on one side close to the stabilizing cylinder 105, the two connecting assemblies 108 are respectively fixedly connected to the two clamping plates 106, and each pass through the stabilizing cylinder 105 to contact with the guide plates 107. The spiral blade 101 is a spiral blade, chip flutes are arranged between the spiral blades, and cutting angles are arranged at the ends of the spiral blades. The spiral cutting edge 101 is connected to machining equipment through the cutter handle 102 to cut metal, the base 104 is placed on a table top, when the spiral cutting edge 101 is not used, the cutter handle 102 is taken down from the machining equipment and then placed between the two clamping plates 106 in the stabilizing cylinder 105, the stabilizing cylinder 105 is rotated, the stabilizing cylinder 105 is enabled to rotate on the base 104, the two connecting assemblies 108 are driven to rotate, the two connecting assemblies 108 are enabled to push the two clamping plates 106 to clamp two sides of the cutter handle 102 under the guidance of the guide plate 107, the cutter handle 102 and the spiral cutting edge 101 are fixed, and the problem that an existing reamer is easy to roll down from the table top to cause damage when not used is solved.

The connecting rod 109 is slidably connected with the stabilizing cylinder 105, penetrates through the stabilizing cylinder 105, and the return spring 110 is fixedly connected with the clamping plate 106, is fixedly connected with the stabilizing cylinder 105, and is located around the connecting rod 109. The connecting rod 109 connects the clamping plate 106 to the stabilizing cylinder 105, the guide plate 107 has an arc plate with a fixed distance from the stabilizing cylinder 105 and a sloping plate with a gradually increasing distance from the end point of the arc plate to the stabilizing cylinder 105, when the clamping plate 106 does not clamp the tool handle 102, the stabilizing cylinder 105 is rotated, so that the connecting rod 109 on the stabilizing cylinder 105 slides from the end point of the arc plate to the sloping plate, at this time, the movable space of the connecting rod 109 is enlarged, and the restoring spring 110 pulls the clamping plate 106 to move to a side far away from the tool handle 102, so that the tool handle 102 is released.

Next, the balls 111 are disposed in the connecting rod 109.

Meanwhile, the friction pad 112 is fixedly connected with the base 104 and is located at a side away from the stabilizing cylinder 105. The friction pad 112 increases the friction between the base 104 and the table top so that the base 104 does not follow the rotation when the stabilizing cylinder 105 is rotated, increasing the stability of the base 104 on the table top.
