Description

Technical Field

[0001] The utility model belongs to the technical field of slicing machines, and particularly refers to a chuck of a slicing machine with a triggering mechanism. Background Art

[0002] The retraction operation of a slicing machine usually uses a mechanical handwheel or circuit board control. Usually, because its retraction is rather cumbersome, time-consuming and laborious, it increases the working intensity of operators and reduces the work efficiency of personnel. When facing a large number of sample tissues, operators are prone to forget the retraction operation, resulting in a serious collision between the sample chuck and the tool holder. As a result, there may be adverse consequences such as sample damage, tool holder damage, reduction of slicing machine accuracy, and safety hazards such as debris splashing caused by blade breakage due to forgetting to retract.

[0003] Therefore, how to automatically retract the blade safely and efficiently has become a problem that needs to be solved urgently. Content of the Utility Model

[0004] The purpose of the utility model is to provide a chuck of a slicing machine with a triggering mechanism that has a stable structure, is safe and efficient, and can automatically retract the blade while replacing the wax block.

[0005] The purpose of the utility model is achieved as follows: A chuck of a slicing machine with a triggering mechanism, comprising:

[0006] A chuck body, having an installation hole at the top, and the surface of the chuck body has an anti-slip portion;

[0007] A fixed clamping block, fixed on the chuck body;

[0008] A movable clamping block, rotatably installed on the chuck body, the movable clamping block and the fixed clamping block cooperate with each other to clamp the embedding frame, and the movable clamping block is used for the open working position and the locked working position;

[0009] A return spring, one end connected to the chuck body, and the other end connected to the movable clamping block, for making the movable clamping block in the locked working position;

[0010] A control handle, one end fixed to the movable clamping block, for pushing the movable clamping block to switch from the locked working position to the open working position, and the other end passes through the installation hole;

[0011] A trigger button, installed on the side wall of the fixed clamping block, and the trigger button abuts against the control handle.

[0012] Preferably, an installation groove is provided on the side wall of the fixed clamping block, and the trigger button is arranged in the installation groove.

[0013] Preferably, an epoxy board is designed between the trigger button and the installation groove.

[0014] Preferably, a limit post is inserted through the movable clamping block, and the limit post is rotatably arranged in openings formed on both sides of the chuck body.

[0015] The prominent and beneficial technical effects of the present utility model compared with the prior art are as follows: The chuck of the microtome with a trigger mechanism of the present utility model aims at the technical problem that each time when changing the wax block, manual retraction of the knife is required, otherwise the knife will collide and damage the blade and the tissue wax block, resulting in medical accidents, and researches an automatic knife retraction function. By adding a contact travel switch between the fixed clamping block and the control handle and adopting one-step control, it is convenient for quickly replacing samples of the same specification, enabling the sample chuck to automatically retract to the most suitable position set in the previous sectioning. When the user replaces the wax block, the trigger button on the fixed clamping block is triggered, and the knife automatically retracts to the previous knife alignment position. When replacing wax blocks of the same specification, secondary knife alignment is not required, which is not only safe but also can improve the sectioning efficiency, and at the same time avoid major accidents of damaging samples during sectioning caused by failure to manually retract the knife; the anti-slip part on the surface of the chuck body can effectively increase the stability of the wax block and improve the sectioning quality.

[0016] Currently, the device returns to the memory position (suitable position) through induction triggering. This technology uses one power source to complete two or more different actions, which not only reduces the manufacturing cost but also simplifies the operation process and improves safety.

[0023] The following further describes the present utility model with specific embodiments.

[0024] Embodiment 1: As Figures 1-3 shown, a chuck of a microtome with a trigger mechanism includes:

[0025] a chuck body 1 with an installation hole 6 at the top, and an anti-slip part 11 on the surface of the chuck body 1;

[0026] The fixed clamping block 2 is fixed on the chuck body 1;

[0027] The movable clamping block 3 is rotatably installed on the chuck body 1. The movable clamping block 3 cooperates with the fixed clamping block 2 to clamp the embedding frame. The movable clamping block 3 is used for the open working position and the locked working position;

[0028] The return tension spring has one end connected to the chuck body 1 and the other end connected to the movable clamping block 3, and is used to make the movable clamping block 3 in the locked working position;

[0029] The control handle 4 has one end fixed to the movable clamping block 3 and is used to push the movable clamping block 3 to switch from the locked working position to the open working position, and the other end is inserted into the mounting hole 6;

[0030] The trigger button 5 is installed on the side wall of the fixed clamping block 2, and the trigger button 5 abuts against the control handle 4.

[0031] For the technical problem that the slicer chuck with a trigger mechanism in this technical solution requires manual retraction of the tool each time when changing the wax block, otherwise it will hit the tool and damage the blade and the tissue wax block, causing a medical accident, an automatic tool retraction function is developed. When the user changes the wax block, the trigger button 5 on the fixed clamping block 2 is triggered, and the tool is automatically retracted to the previous tool setting position. When changing wax blocks of the same specification, there is no need for secondary tool setting, which is not only safe but also can improve the slicing efficiency.

[0032] The trigger button 5 is arranged on one side of the fixed clamping block 2. When the user changes the wax block, the control handle 4 needs to be moved. The control handle 4 leaves the trigger switch trigger signal, and the signal is transmitted to the control board, and the control board controls the motor to achieve safe and efficient tool retraction.

[0033] Providing an anti-slip portion 11 on the surface of the chuck body 1 can effectively prevent the wax block from shaking during the operation of the slicer. A frictional force can be generated between the anti-slip portion 11 and the wax block, so that the control handle 4 does not need to be made very tight, facilitating the operator to load and unload the wax block.

[0034] Preferably, an installation groove 7 is provided on the side wall of the fixed clamping block 2, and the trigger button 5 is arranged in the installation groove 7.

[0035] Preferably, an epoxy board 8 is designed between the trigger button 5 and the installation groove 7.

[0036] Preferably, a limit post 9 is inserted into the movable clamping block 3, and the limit post 9 is rotatably arranged in the openings 10 provided on both sides of the chuck body 1.

[0037] Such as Figure 4As shown in the figure, Embodiment 2: This embodiment is basically the same as Embodiment 1, and the difference lies in that a trigger button 5 adapted to the control handle 4 is provided on one side of the chuck body 1. When the control handle 4 swings left and right, it can touch the trigger button 5 to achieve simultaneous automatic tool withdrawal and wax block loading and unloading.

[0038] As Figure 5 shown in the figure, Embodiment 3: This embodiment is basically the same as Embodiment 1, and the difference lies in that a travel switch 40 is provided on the chuck body 1. The travel switch 40 is triggered when the control handle 4 moves a certain distance to achieve simultaneous automatic tool withdrawal and wax block loading and unloading.

[0039] As Figure 6 shown in the figure, Embodiment 4: This embodiment is basically the same as Embodiment 1, and the difference lies in that a photoelectric switch 50 is provided on the chuck body 1. The photoelectric switch 50 is set to be triggered when the set condition is no longer met due to a change in the position of the control handle 4 during movement to achieve simultaneous automatic tool withdrawal and wax block loading and unloading.

[0040] The above embodiments are only preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
