[0004] The utility model intends to provide a kind of scion cutting device, to solve the problem that existing cutting device cannot flexibly adjust the cutting angle.
[0005] In order to achieve the above purpose, the utility model provides the following technical scheme:
[0006] The utility model provides basic technical scheme: a kind of scion cutting device, including base, the base rotationally connected with first knob and cutting platform, the cutting platform slidingly connected with cutting frame, the cutting frame is fixedly connected with cutting blade, the base is equipped with recess, the recess rotationally connected with bidirectional screw rod, the bidirectional screw rod one side is through the base and is connected with the first knob fixedly, the bidirectional screw rod both sides are all screw-connected with clamping block, the base is fixedly connected with support frame, the support frame rotationally connected with second knob and screw column, the screw column one side is through the support frame and is connected with the second knob fixedly, the support frame slidingly connected with support rod, the support rod is screw-connected with the screw column, the support rod rotationally connected with connecting rod, the connecting rod other side is rotationally connected with the cutting platform.
[0007] The principle of the basic technical solution is: when the first knob is rotated, the bidirectional threaded rod fixedly connected with the first knob is rotated, since the threads on the two sides of the bidirectional threaded rod are opposite in rotation direction and the two sides are both threadedly connected with the clamping blocks, the rotation of the bidirectional threaded rod will make the two clamping blocks move in the opposite or opposite directions in the groove based on the thread transmission principle, so as to realize the clamping and loosening of the shoot; when the second knob is rotated, the threaded column fixedly connected with the second knob will rotate. Since the support rod is threadedly connected with the threaded column and is slidingly connected with the support frame, when the threaded column is rotated, the support rod will move along the threaded column under the action of thread transmission, and in the moving process of the support rod, the connecting rod rotatingly connected with the support rod will move, and the other end of the connecting rod drives the cutting platform to rotate around the base, so as to adjust the angle of the cutting platform; when the cutting frame is slid, since the cutting frame is slidingly connected with the cutting platform, the cutting frame will move on the cutting platform. At the same time, the cutting blade fixed on the cutting frame will also move, so as to cut the clamped shoot.
[0008] The beneficial effects of the basic technical solution are: in terms of operation, the first knob is rotated to drive the bidirectional threaded rod to make the clamping blocks quickly clamp and loosen the shoot, the second knob is rotated to drive the threaded column to adjust the angle of the cutting platform, and the cutting frame is slid to flexibly control the cutting blade, so that the overall operation is simple and efficient, and the working difficulty of the operator is reduced; in terms of structural stability, the cooperation of the bidirectional threaded rod with the clamping blocks, the support frame with the support rod and the like ensures the stable clamping of the shoot, the accurate angle adjustment and the smooth cutting process, and improves the cutting quality and reliability. In terms of universality, the bidirectional threaded rod driving the clamping blocks can adapt to shoots of different thicknesses, and the multi-angle adjustable cutting platform can meet different cutting requirements, so that the application range of the device is expanded.
[0009] Preferably, first support frames are symmetrically fixedly connected on the two sides of the cutting platform, and guide grooves are arranged on the first support frames.
[0010] Through the above arrangement, the first support frames and the guide grooves are symmetrically arranged on the two sides of the cutting platform, and the cutting frame is connected with the matching guide rods, so that the cutting frame can be effectively guided to slide stably, the deviation or shaking of the cutting frame in the moving process is prevented, the cutting process is stable, and the precision and quality of the shoot cutting are improved.
[0011] Preferably, second support frames are symmetrically fixedly connected on the two sides of the cutting platform, springs are fixedly connected in the second support frames, movable blocks are fixedly connected on the other sides of the springs, and the movable blocks are fixedly connected with the guide rods.
[0012] Through the above setting, when the cutting frame drives the cutting blade to complete the cutting of the cutting piece, the spring elastic potential energy can be relied on to realize automatic rebound reset, so as to prepare for the next cutting operation, and the continuity and efficiency of the cutting operation are greatly improved.
[0013] Preferably, the first knob and the base are rotatably connected through a bearing, and the second knob and the support frame are rotatably connected through a bearing.
[0014] Through the above setting, the bearing is used for rotatable connection between the first knob and the base and between the second knob and the support frame, so that the rotating friction force can be greatly reduced, the knob can rotate more smoothly, the operation is more labor-saving, the service life of the components can be prolonged, the stable operation of the device can be ensured, and the overall operation experience is improved.
[0015] Preferably, the clamping block is in a T shape, and the bottom width of the clamping block is slightly smaller than the width of the groove.
[0016] Through the above setting, when the bidirectional threaded rod rotates, the clamping block can be prevented from rotating, so that the two clamping blocks only move linearly along the groove in opposite directions or in the same direction, and the stability and accuracy of the cutting piece clamping operation are ensured.
[0017] Preferably, anti-skid lines are arranged on the first knob and the second knob.
[0018] Through the above setting, the friction force between the hand and the knob contact surface is increased, the slipping during operation is avoided, the knob can be rotated more labor-saving and stably, especially in a wet and slippery environment or during long-time operation, the holding comfort and control accuracy can be effectively improved, and the smoothness of clamping and angle adjustment is ensured.
